RELATED APPLICATIONS This application claims the benefit of and is a continuation of U.S. patent application Ser. No. 13/419,038, filed on Mar. 13, 2012, and entitled, “Ballistic and Impact Protective Military Helmet Assembly”, which claims the benefit of U.S. Provisional Application 61/452,462, filed Mar. 14, 2011, each of which is incorporated herein in its entirety.
REFERENCE TO GOVERNMENT FUNDING This invention was made with Government support under Contract No. W911QY-10-C-0121, awarded by the U.S. Army Material Command, a division of the United States Department of Defense. The Government has certain rights in this invention.
TECHNICAL FIELD OF THE INVENTION The present invention relates to helmet assemblies having multiple components such as face shields, mandibles, or mouth guards and accessories.
BACKGROUND OF THE INVENTION A number of protective and military helmets are known, such as the helmet known as the Advanced Combat Helmet (ACH), which was a successor to the Personnel Armor System Ground Troops (PASGT) such as shown in US Patent Des. 242,088. Further, military and law-enforcement helmets with face shields are known such as disclosed in U.S. Pat. Nos. 5,901,369 and 4,536,892. These face shields provide pivot arrangements on opposite lateral sides of the face shield to allow the face shield to be pivoted upward away from the user's face when the face shield is not deployed. The face shield is held in a deployed position in front of the user's face by locking of the pivot arrangements.
The present inventors recognize a need for a helmet with increased coverage, improved ballistic performance, improved impact performance, and improved freedom of movement. The inventors recognize a need for a helmet that has a closer conformity with the user's head and is lighter with improved equipment compatibility. The inventors further recognize a need for a redesign communication system to fit within their revised helmet having a closer conformity with a user's head.
The present inventors have recognized that it would be desirable to provide a helmet assembly with an improved attachment system for attaching a face shield, a mandible, goggles, heads-up displays, GPS units, batteries, communication systems, and other accessories.
The present inventors also recognize that it would be desirable to provide an attachment system that was quickly and easily installed onto, or removed from, a helmet. The present inventors recognize a need for the lower edge of the helmet to carry power and/or data over one or more conduits.
The present inventors recognize a need for a helmet with anchor mounts formed in the helmet shell and thereby eliminate the need for through holes that are generally found in certain prior art helmets for mounting accessories.
Some prior art helmet strap systems have as many as five buckles or points of adjustment for adjusting the various straps used to secure the helmet to a user's head. The inventors recognized a need to eliminate the several buckle strap adjustments of the prior helmet strap systems. The present inventors recognize a need for improved helmet retention system that reduces complexity and one in which a user may operate with only one hand.
The present inventors further recognize a need for a face guard or mandible that provides access to a user's mouth. Further, the present inventors recognize a need for a mandible that is removable with one hand by a centrally located release mechanism.
SUMMARY OF THE INVENTION An exemplary embodiment of the invention provides a helmet assembly including a front mount configured to attached to the front of the helmet above a brim of the helmet, a mandible for protecting a portion of the user's face, an accessory-mounting rim portion, such as a “halo”, attached along the lower edge of the helmet for securing the mandible to a helmet and providing power and data conduits, and attachment location for other accessories.
In one embodiment, the helmet assembly includes a face shield and the front mount provides a center top mounting arrangement that operatively connects a center top location of the face shield to a center front mount on the helmet. The face shield can be raised and lowered about a pivot axis provided in the mounting arrangement between a tilted up, non-use position and a lowered, deployed position.
In one embodiment, the front mount includes left and right bracket portions that extend laterally across a portion of the front of the helmet adjacent to the brim. The bracket portions have edge lips on sides of the bracket portion for retaining an accessory. The edge lips can be upper and lower edge lips that extend vertically toward each other. Each bracket portion has a rearward extending lateral accessory engagement portion for attachment of accessories, such as an LED.
In one embodiment, the helmet assembly has a helmet that includes a right and left ear coverage areas, an upper portion, a stiffening ridge, a rear portion, and a bottom edge. The rear coverage areas are connected to the upper portion on opposite lateral sides. The rear portion is connected to the upper portion at the rear of the helmet shell. The stiffening ridge joins the each ear coverage area with the upper portion. The stiffening ridge also joins the rear portion with the upper portion.
The stiffening ridge offsets the upper portion from the left ear coverage area, the right ear coverage area, and the rear portion. The offset between the upper portion and rear portion is less than the offset between the upper portion and each of the ear coverage areas. The helmet can comprise at least two steps along the lower edge. The lower most portion of the rear portion is below the lower most portions of the ear coverage areas to provide increase head and neck protection in the rear. The helmet shell comprises an upper brim edge and the stiffening ridge bridges between the upper brim edge and the ear coverage areas at a front of the helmet. The stiffening ridge extends from the brim edge on a first side of the helmet continuously around the helmet to the brim edge on a second side of the helmet.
The helmet can have a center anchor, opposite lateral front anchors, and a rear anchor. Each anchor is formed on the outside surface of the helmet shell, therefore all helmet through-holes are eliminated. The center anchor and the rear anchor can be centered on the front-to-back midplane of the helmet.
The accessory-mounting rim portion, such as a halo, has at least two steps as shown from a side view that match the two steps of the lower helmet edge. Therefore, the accessory-mounting rim portion has a form the matches the continuous edge of the helmet along its circumference around the helmet.
In one embodiment, the accessory-mounting rim portion comprises a hook receiver and a locking pin recess for securing the mandible to the accessory-mounting rim portion. The hook receiver is located ahead of the locking pin recess. The accessory-mounting rim portion has a strike plate adjacent to the locking pin recess for buffering or absorbing contact between a pin of the mandible and the accessory-mounting rim portion before the pin engages the recess.
In one embodiment, the accessory-mounting rim portion comprises a power conduit, a computer data conduit, or both. The accessory-mounting rim portion may have a rear port for receiving a cable connection where the cable connection may be capable of carrying power or data or both.
In one embodiment, the helmet assembly has a battery configured to attach to the rear of the accessory-mounting rim portion and extend upward along the rear of the helmet. The battery may be in communication with the conduits of the accessory-mounting rim portion for powering accessories attached to the helmet.
In one embodiment, the helmet assembly has a GPS holder attached to the rear anchor.
In one embodiment, the mandible comprises right and left cheek protecting portions connected at the front by a mouth protecting portion and the mouth protecting portion has a front cover that is openable by a pivotal connection with the mouth protecting portion. The cover has a closed position for protecting a user, an open position for permitting access to a user's mouth, and a release position that actuates a release mechanism for releasing the mandible from connection to the lower edge accessory-mounting rim portion.
A mounting mechanism of the mandible has a hook and a sliding pin at the rear of each of the left and right cheek protecting portions. The hook is configured to pivotally engage a hook receiver such as a hook engaging element, a hole or a bar on the accessory-mounting rim portion and the pin is configured to engage a locking pin recess on the accessory-mounting rim portion. This arrangement provides a pivotal one hand attachment and detachment of the mandible from the accessory-mounting rim portion.
In one embodiment, the helmet assembly includes a heads-up display releasably securable to the bracket portion of the front mount. The heads-up-display may have a retractable display screen that is positioned inside the visor. The heads-up display may receive power and data from the conduit(s) of the accessory-mounting rim portion.
In one embodiment, the helmet assembly has a communications system with a pair of ear cups in signal communication with the accessory-mounting rim portion. The ear cups have a speaker and padding for providing a predefined level of ear protection from external sound sources. The ear cups have a reduced depth to be configured to fit between the conformal helmet shell and a user.
In one embodiment, the helmet assembly has a helmet retention system for securing the helmet to a user's head. The helmet retention system is adjustable by one hand. The retention system has a front chin contact strap for crossing the front of a user's chin, a lower chin contact strap for extending under a user's chin, a first reel rotatable to tighten or loosen the front chin contact strap, a second reel rotatable to tighten or loosen the lower chin contact strap. A first reeling strap connects the ends of the lower chin contact strap to the first reel, and a second reeling strap connects the ends of the front chin contact strap to the second reel. The first and second reels may be located on the accessory-mounting rim portion at the rear of the accessory-mounting rim portion.
In one embodiment, the helmet assembly has a goggle clip receiver mount attached to the rear of the accessory-mounting rim portion. A pair of goggle clips are connectable with securing straps of a goggle and the goggle clips are releasably securable within the goggle clip receivers to secure goggle straps around to the rear of the helmet. The goggle clip receiver mount may include a battery that is signal connected with the accessory-mounting rim portion.

DETAILED DESCRIPTION While this invention is susceptible of embodiment in many different forms, there are shown in the drawings, and will be described herein in detail, specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.
For ease of description, the helmet assembly and associated apparatuses herein will be described generally according to an orientation where a wearer is wearing the helmet and facing in a forward direction. Thus, the helmet has a front and forward direction corresponding to the forward direction, a rear or back spaced from the front in an opposite rearward direction, opposite sides laterally spaced apart on a left and right of the front, an upper or top corresponding generally to a direction directed toward the sky and lower or bottom generally corresponding to a downward direction directed toward the ground.
It should be noted that the helmet assembly described herein is symmetrical across a vertical, front-to-back midplane 167 (FIG. 2) as evidenced by the figures and any description of a right side component will also describe the left side component as a mirror image thereof.
FIGS. 1-4 illustrate a helmet assembly 100 to be worn by a user or wearer 31 (FIG. 7) according to an exemplary embodiment of the invention. The helmet assembly includes a helmet 134, an accessory-mounting rim portion 200, such as a halo, attached to the lower edge of the helmet, a mandible operatively connected to the helmet by the accessory-mounting rim portion 200. A protective face shield, such as a transparent visor or transparent face shield 138 is also operatively connected to the helmet, substantially between a front of the helmet 134 and the mandible 300. A mounting arrangement 142 is operatively connected to the helmet 134 and to the face shield 138 which allows movement of the face shield 138 with respect to the helmet. The mounting arrangement 142 includes a shield mount 142e and a front helmet mount 144.
Helmet Referring to FIGS. 5-10H, the helmet 134 has a conformal shell that more closely matches the shape of a user's head as compared with prior art helmet 10, such as the traditional bell shaped helmets, including the ACH. A prior art helmet 10 is shown in FIGS. 11A-F. The bell shaped helmets get wider, as shown by directional arrows B in FIG. 11B, at the bottom with increased helmet size. This is in contrast to conformal shells of the helmet 134 which do not get wider at the bottom as the size of the helmet increases.
One reason why bell shaped helmets exist is that they are formed with a matching die set in a mold arrangement. The matching die set includes a male part and a female part, where the helmet is formed their between. A bell shaped helmet is required in such a mold otherwise the helmet could not be removed from the female shaped part of the mold—without great difficulty, if at all—because the conformal shape of the helmet was adhere to the female mold portion. However the conformal shell helmet 134 may be manufactured using a flexible bladder on at least one side of the mold so that the bladder may be collapsed after molding is complete and apart removed without any adherence problems to a female portion of the mold such as exists with match die type molds.
FIG. 5-10 shows the helmet 134 having, right and left ear coverage areas 146, an upper portion 147, a stiffening ridge 140, a lower rear portion 143, a bottom edge, and a plurality of anchors or mounts 115, 116, 118, 119. Although four mounts are shown, it is encompassed by the invention that one, two or three of the mounts are used. The ear coverage areas 146 and the lower rear portion 143 are contiguous with the upper portion 147 of the helmet via a stiffening ridge 140. The stiffening ridge 140 comprises opposite side stiffening ridge portions 140c and a rear stiffening ridge portion 140d. The rear stiffening ridge portion 140d extends between opposite rear stiffening ridge ends 146b. The side stiffening ridge portions 140c are continuous with the rear stiffening ridge portion 140d. The rear stiffening ridge 140d connects the lower rear portion 143 with the upper portion 147, as shown in FIGS. 7 and 8.
The ear coverage areas provide addition space within the helmet to accommodate a user's ear and communication equipment that may be needed in the ear area. As shown in FIGS. 9, 10C, and 10G, an outside lateral offset 140e between an outside surface of the upper portion 147 and an outside surface of the ear coverage areas 146 is greater than a rear outside offset 142a between an outside surface of the upper portion 147 and an outside surface of the lower rear portion 143. Similarly, the inside lateral offset 140f between inside surface of an upper portion 147 and inside surface of the ear coverage areas 146 is greater than rear inside offset 142b between the inside surface of the upper portion 147 and the inside surface of the lower rear portion 143.
The outside lateral offset 140e increases from the ends 146b toward the front of the helmet along the ear coverage areas to a max point in the ear coverage areas. The stiffening strength of the stiffening ridge 140 is enhanced by the fact that the side stiffening ridges 140c are contiguous and/or joined with the rear stiffening ridge 140d. The stiffening is achieved by the offset of the ear coverage areas 146 and the lower rear portion 143 from the upper portion 147.
Referring to FIGS. 5 and 6, the bottom edge of the helmet comprises a top eyewear area edge or upper brim edge 166, opposite eyewear area edges 163, opposite ear area lower recessed edges 164, opposite ear area to lower back edge transitions 165, and a lower back edge 162. The top eyewear area edge 166 is contiguous with the respective opposite eyewear area edges 163. The opposite eyewear area edges 163 are contiguous with the respective ear area lower recessed edges 164. The lower ear area to lower back edge transitions 165 are contiguous to the areas 164 and are contiguous with the lower back edge 162. FIG. 7 shows that his configuration results in the helmet having a two-step side profile created by the ear area lower recessed edges 164 and the lower back edge 162. Also, the stiffening ridge 140 has an upward slope from a top eyewear area edge 166 to the midplane 167 at the back of the helmet.
The side eyewear area edges 163 are recessed at a height and depth relative to the helmet to create compatibility with eyewear, such as goggles and visors, and to provide substantially an unobstructed view for the user. The maximum distance between the inside surface of the right ear coverage area 146 and the corresponding left ear coverage area 146 is less than the prior art ACH military helmet, improving conformity with a users head.
The helmet comprises an eyewear recessed area 160 and an under-ear recessed area 161. The eyewear recessed area 160 extends from the top eyewear area edge 166 to the bottom edge of the ear area lower edges 164. It will be understood that eyewear or visors may extend below the eyewear recessed area 160 when mounted to the helmet. The under-ear recessed area 161 extends from the ear area lower edge 164 to the lower back edge 162.
Referring to FIGS. 6-8, the top eyewear area edge 166 slopes upward from the opposite stiffening ridges 140c to the center 166a of the top eyewear area edge 166 at the midplane 167. The lower back edge 162 slopes downward from the ends 162c, 162e of the lower back edge transitions downward toward a center 162b of the lower back edge at the midplane 167. The center 162b is the vertically lowest point of the helmet when upright standard position. A span 168 exists between the ends 162c, 162e and the center 162b. The distance between the ends 162c and 162e is greater than the distance between the opposite ends 146b of the rear stiffening ridge portion 140d.
As shown in FIGS. 5, 7, 8, and 10F, the rear portion 143 of the helmet has a bottom band or portion 170 extending across the back of the helmet that corresponds to the under-ear recessed area 161. The bottom portion 170 is the portion of the rear portion 143 that extends below the ear area lower recessed edge 164. The bottom portion 170 provides addition rear head and neck protection.
As shown in comparison FIGS. 1OF and 11F, the helmet 134 extends further down the neck of the wearer with the bottom portion 170 than the depicted prior art helmet.
As shown in FIGS. 7, 10, and 10G, the rear portion 143 has an inward curve toward the user in the direction I as the rear portion 143 extends downward from the rear stiffening ridge portion 140d to an inner back face 162a at the lower back edge 162. The inward curve provides for an offset 143a between the stiffening ridge and the inner back face 162a of the lower back edge 162.
The arc of the upper portion 147 meets the arc of the rear portion 143 in the rear stiffening ridge portion 140d at the rear most point 142c. The rear most point 142c of the helmet, when in the upright standard position, is located at the rear of the helmet in the stiffening ridge 140d. The rear most point 142c is located above the top eyewear area edge 166 when the helmet is in the upright standard position, as shown in FIG. 7. The rear stiffening ridge 140d at the midplane 167 is located above the top eyewear area edge 166 when the helmet is in the upright standard position. Therefore the rear portion 143 extends vertically from above top eyewear area edge 166 downward.
The location of the user ear recessed area is provided to allow situational awareness. The situational awareness is achieved by a closer conformity of the helmet 134 to the user's head as well as the extent to which the ear coverage areas 146 extend downward. Each of these attributes allows a user to detect activity in the peripheral part of their vision where that vision is not blocked by the helmet. The bottom portion 170 extends below the ear area lower edges 164 and provides additional protection to the head and neck area, while maintaining the needed amount of freedom of movement with respect the user's head. The bottom portion 170 extends laterally from the midplane 167 to the point where the ear area-to-lower back edge transitions 165 begin. Therefore, the bottom portion 170 extends around a user's neck to include a portion of the side of the user's neck as shown in FIG. 7.
In one embodiment, as shown in FIG. 10D, the rear portion 143 of helmet has a vertical radius 150 of about 19.7 inches. The slope of the rear portion has an inward trajectory with respect to the center of the helmet 134. As shown in FIG. 11D, at least one version of a prior art helmet has a rear portion with a vertical radius of about 25.9 inches. The slope of the rear portion has an outward trajectory with respect to the center of the helmet 10.
In one embodiment, as shown in FIG. 10E, the lower back edge 162 of the helmet 134 has a horizontal radius 148 of 4.1 inches. At least one version of the prior art helmet 10 has a lower edge with a horizontal radius of 4.7 inches.
In one embodiment, the area between the inside surface of the helmet 134 and an exemplary user's head is 0.162 square feet, whereas the area between the same exemplary user's head and the inside surface of the helmet 10 is 0.200 square feet.
The inside surface of the helmet 134 is offset from a users head by about 0.75 inches. A padding 740, shown in FIG. 10H, provided on the inside of the helmet 134 creates the offset between the user's head and the inside surface of the hard portion of the helmet 134 when worn by a user. The padding may comprise an energy absorbing material 741, 743, 745, 747, 751, 761 and a comfort enhancing material 742, 744, 746, 748, 750, 760 such as a closed cell foam. In one embodiment, the energy absorbing material comprises one half inch in thickness, and the comfort enhancing material comprises a one fourth inch in thickness. The energy of absorbing material is attached to a carrier base 764 creating a one piece design that can be efficiently manufactured and installed. The carrier based may comprise fabric. The comfort enhancing material is mounted on, such as being adhered to, a top of the energy absorbing material.
Padding is provided in a forehead contact region 741, 742, two lateral side contact regions 744, 743, 746, 745, and two rear contact regions 748, 747, 750, 751. The lateral side contact regions are smaller than the forehead contact region as well as the rear contact regions. A top head central contact region 760, 761 is positioned substantially centrally with respect to the forehead contact region, the lateral side contact regions, and the rear contact regions. However, it is not required that the top head contact region may be located centrally. A forward intermediate region 752 is located on the carrier base 764 between the forehead region and the top contract region. Side intermediate regions 753,754 are located on the carrier base 764 between the opposite lateral side regions 744, 746 and the central region 760, respectively. Rear intermediate regions 755, 756 are located on the carrier base 764 between the two rear contact regions 748,750 and the central region 760, respectively.
The padding 740 forms a substantially star shape when laid flat. The carrier base material 764 of the padding 740 is flexible to conform the padding to the inside surfaces of the helmet when the padding is installed. The backside of the base material 764 may include an adhesive to secure the padding to the inside surface of the helmet 134.
The offset provided by the padding between the helmet and the user's head improves blunt force impact performance of the helmet as well as the backface deformation performance of the helmet. Backface deformation may be understood as the effect of a non-penetrating projectile on the rear face of a strike plate or surface being struck by the projectile.

Below the side ridge 336 the rear of the mandible has a forward sloping section 332a which connects the side edge 336 to the scooped lower edges 333.
Referring to FIGS. 15-19, the mandible comprises a mandible mounting system 370. Only one side of the mandible mounting system 370 will be described with the understanding that an identical configuration would be present on the opposite side of the helmet and mandible, i.e., there would be two pins, two hooks, two cords, etc. The mounting system 370 comprises an anchoring hook 340 and pin engagement system 365, and the cover 320. The pin engagement system 365 comprises a pin 360. The pin 360 comprises an engagement portion 361, a recess portion 362, and an anchor portion 363. The recess portion 362 connects the engagement portion 361 to the anchor portion 363.
Engagement portion 361 and the recess portion 362 are configured to operate in the pin channel 374 of the mandible. The pin channel 374 extends to the rear of the mandible to exit holes in mounting contact surfaces 335b so that the pin can engage locking pin holes 265b of the accessory-mounting rim portion 200. The pin channel 374 is open to a reduced diameter channel portion 379a through an opening in a base end wall 379 opposite to the exit holes. The reduced diameter channel portion 379a opens into a slide channel 372. The slide channel 372 allows the anchor 363 of the pin to move longitudinally within this slide channel as shown by the arrow D, in FIG. 17. The slide channel limits the movement of the anchor 363 and thereby limits the travel of the pin 360.
The pin engagement system 365 comprises a spring 362a (shown schematically). The spring is fit around the recess portion 362 of the pin within the pin channel 374 braced between a wall 361a of the engagement portion 361 of the pin and the base end wall 379 of the channel. The slide channel extends between a rear end 373 and a front end 375 of the slide channel. The rear end 373 is open to the reduced diameter channel portion 379a to receive the recess portion 362 of the pin therethrough. The spring 362a, by being compressed, pushes between the base end wall 379 and the wall 361a of the engagement portion 361 to draw the anchor 363 against the rear end 373 of the slide channel 372. The anchor 363 is attached to a cable element, such as a cord 351 of the cable 350. The cable element 351 may be attached around the anchor 363 or may be attached to a front surface of the anchor 363. The cable element 351 is movable within the cable 350.
The cable element is moved within the cable 350 by the cover 320. In one embodiment shown in FIG. 16, the cable element 351a extends between the front surface 312 and the inside surface of the cover 320. The cable element may have a slack portion at an end opposite the pin. The cover may house the slack portion. The slack portion has an end with an anchor. The anchor is retained within a container portion of the cover when the cover is in a closed position. The slack portion reels from the cover as a cover moves upwards towards an open position. When the cover reaches a predefined release position 320a, the anchor of the slack portion engages an anchor stop of the cover 320 and the cable element 351 is drawn through the cable 350 to draw the pin 360 forward. Once the cover is moved past the release position, the cable element begins to be drawn forward which draws the pin 360 forward releasing it from engagement with the locking pin holes 265b of the accessory-mounting rim portion. When the pin is released, the mandible may be pivoted about the hooks 340 temporarily and then moved back down to re-engage the pins 360 with the locking pin holes 265b of the accessory-mounting rim portion. Alternatively the hooks may be disengaged with the hook anchors 263b and the mandible may be removed from the accessory-mounting rim portion.
A user is allowed to open the cover and permit hydration or access to the mouth without releasing the mandible from the accessory-mounting rim portion by moving the cover anywhere between the closed position and a full release position 320e. Because the cover operates to release the pin engagement system 365, a user may remove the mandible by using only one hand. This is accomplished by the user lifting the front cover from the start-to-release position 320a to the full release position 320e, where the pins disengage with the locking pin holes and then user continues lifting the cover or other part of the mandible to release the hooks from the hook anchors 263b.
In another embodiment, the cable 351b runs up the center portion 310 and connects to a winding mechanism that is attached to the pin 324. The winding mechanism pulls the cable element towards the front of the mandible when a user draws the cover 320 between the release position 320a and the full release position 320e. And this draws the anchor portion 363 forward in the slide channel 372 to draw the pin 360 forward. In one embodiment, the winding mechanism has a detent mechanism. The detent mechanism prevents the cable element from being pulled through the cable 350 until the cover reaches the release position 320a. Once the cover is moved past a predefined released position, the cable element begins to be drawn forward which draws the engagement portion of the pin 360 forward releasing it from engagement with the accessory-mounting rim portion.
Referring to FIG. 18, to attach the mandible to the accessory-mounting rim portion 200, the front of the mandible is raised up toward the top eyewear area edge 266 of the accessory-mounting rim portion and the anchor hooks 340 engage the hook anchor holes 263a of the accessory-mounting rim portion. Then the front of the mandible is pivoted down away from the top eyewear area edge 266 and at the same time the rear of the mandible is pivoted up about the anchor hook 340 in the direction E shown in FIG. 18 until the pin 360 engages the locking pin holes 265b and the mounting contact surface 335a, 335b contact or are in close proximity to the ear area lower cut edges 264 and ear area to lower back edge transitions 265 of the accessory-mounting rim portion, correspondingly. Before the pins 360 engages the locking pin holes 265b the pins contact the strike plate 265a there the movement of the mandible relative to the accessory-mounting rim portion compresses the pin inwards towards the mandible until the pin is in line with the locking pin holes 265b. When the pins engage the locking pinholes and springs into the pinholes under the force of the spring, the mandible is secured against the accessory-mounting rim portion between the hook anchor and the pin.
FIGS. 19 and 20 show an alternate shorter profile mandible 400 which is similar to mandible 300 except as described and shown. The alternate mandible 400 is similar to the first full mandible 300 except that the alternate mandible 400 does not have the lower portion 332 found on the first mandible 300. The shorter profile of the mandible 400 allows increased compatibility with shoulder mounted weapons. Further, it provides additional freedom of movement to the user. The upper portion 434 of the mandible 400 is similar to the upper portion 334 of the mandible 300. Correspondingly, the center portion 310 of the mandible 300 is similar to the center portion 410 of the mandible 400. The cover 420 of the mandible 400 is configured and operates in the same manner to the cover 320 of the mandible 300. The mandible 400 has the same mounting system as the mandible mounting system 370 of the mandible 300. The mandible provides ballistic resistance, impact resistance, and blast resistance to the user's cheek, mandible, and partial neck regions.
The mandible may be made of a rigid material and or may carry a removable ballistic fabric that is carried around a frame structure. In other embodiments the mandible may comprise a wireframe guard without any ballistic protective material surrounding it. In one embodiment the lower portion 332 comprises they semi-flexible frame or material. Semi flexible frame mandibles or guards provide the benefit of conforming to a weapon when the wearer is aiming with a stock of the weapon proximate the cheek of a user to enhance the user's ability to use citing functions of weapons.

In one embodiment, the mandible is any of the mandibles disclosed in U.S. patent application Ser. No. 12/875,106, filed Sep. 2, 2010, which is herein incorporated by reference to the extent not inconsistent with the present description.
Head's Up Display The helmet assembly 100 may comprise a heads-up display usable with the front mount 144 as shown in FIGS. 21, 22, 22A, 22B. FIGS. 22A and 22B show the heads-up display transparently so that some internal components are visible. The heads-up display 500 has a recessed area 515 with an upper engagement rail 510 and a lower engagement rail 511 for engaging the right or left bracket portions 180, 181 of the front mount 144. The heads-up display 500 has a display screen 502. The display screen 502 has a deployed position as shown in FIGS. 21 and 22 and a retracted standby position (not shown) where the display screen 502 is retracted upward in the direction G as shown in FIG. 52 to withdraw the screen from the user's view and to withdraw the screen within a heads-up display 500 or within a slotted or recessed area (not shown) in the front mount 144, such as in the side bracket portion 180 or 181.
An upper portion of the upper engagement rail 510 comprises an upper rail lip 512 and a lower portion of the lower engagement rail 511 comprises a lower rail lip 513. The upper rail lip 512 engages the inside surface of lip 187 of the front bracket and the lower bracket lip 513 engages the inside surface of lip 184 of the front bracket portion to secure the heads-up display 500 to one of the left or right bracket portions 180, 181. A heads-up display has a release mechanism which when the release mechanism is activated, for example via button 503, the upper engagement rail 510 and the lower engagement rail 511 draw closer to each other in the gap area 514 to release the lips 512, 513 from the lips 184 and 187 of the front bracket portion.
In some embodiments, the release mechanism is that shown in FIGS. 22A and 22B. The release mechanism comprises the button 503 that is connected to a guide plate 504 by a protruding connecting bar 504a that are securely connected in a recess of the button 503. The guide plate has lower diagonal guide slots 505a, 505b and upper diagonal guide slots 505c, 505d. The lower engagement rail has two lower guide rods 506a, 506b that are fixed to the lower engagement rail. The upper engagement rail has upper guide rods 506c, 506d that are fixed to the upper engagement rail. The guide rods extend transversely to the longitudinal orientation of the guide plate 504 and pass through the respective guide slots. When the button 503 is pushed in the direction H the guide plate 504 moves in direction H relative to the body 519 of heads-up display 500 and the lower guide rods 506a, 506b are driven upward in the direction J by the lower edge of each of the lower diagonal guide slots 505a, 505b. Simultaneously, the upper guide rods are driven downward in the direction I by the upper edge of each of the upper diagonal guide slots 505c, 505d. As the upper and lower guide rods are fixed to the upper and lower engagement rails, then likewise the upper engagement rail 510 is driven downward in the direction I and the lower engagement rail 511 is driven upward in the direction J by the movement of the guideplate relative to the guide pins. In this way the upper engagement rail 510 and the lower engagement rail 511 draw closer to each other in the gap area 514 to a contracted position to release the lips 512, 513 from the lips 184 and 187 of the front bracket portion. In some embodiments the upper and lower engagement rails contact each other in the gap area 514 when in the contracted position. In some embodiments there a spring 504m (shown schematically) that biases the button 503 and/or the guide plate 504 relative to the body 519 of heads-up display 500 in the direction opposite of direction H so that the upper engagement rail 510 and the lower engagement rail 511 are biased toward the expanded position as shown in FIGS. 22, 22A, and 22B.
The heads-up display 500 has data and power connections (not shown) that are connectable with power and data connections within the front mount or bracket portions 180, 181 which are in turn in communication with the accessory-mounting rim portion 200 and the power and data connections provided therethrough.
As is shown in FIG. 21 the display screen 502 can be positioned behind the face shield 138 when the display screen is in the deployed position. The face shield or the frame or gasket thereof and/or the mount 144 are configured to have a gap or slot to allow the display screen to slide between the face shield or visor and the helmet. In this configuration, the visor, such as a visor with a tint, would not obscure the data or images being displayed on the display screen 502. In addition, the visor will protect the screen from environmental hazards. In one embodiment the display screen 502 is a transparent so that the display screen does not create a blind spot in the field of view of the user. In this configuration the user may be able to see through the data and images displayed on the transparent display to maintain awareness of the user's environment. The heads-up display 500 may be amounted on either the right or left side bracket portions 180, 181 of the front mount 144. Alternatively, the display screen can remain outside the face shield in the deployed position.
A recessed area 515 allows the heads-up display 500 to be a mounted in close conformity with the helmet in a low-profile design. Therefore the top portion 516 may be in close proximity or in contact with the helmet 134 and likewise the display screen support 517 positions the display screen 502 on the interior side of the face shield 138 and the visors support frame. In addition the center portion 518 has a curved profile so as to allow the upward movement of the visor.
An external heads-up display 520 is shown in FIGS. 23, 23A. The external heads-up display 520 has a base unit 527 with a display screen 522. A cable is connected to the base unit 526. The cable is capable of carrying data and electrical power the unit. The cable may connect to the rear of the accessory-mounting rim portion or may connect to an external source. The base unit 527 is supported by a supporting mechanism which includes a first arm 524 having a first ball mount connection 525 to a first base 530 and a second ball mount connection 529 connected to the base unit 527. Each ball mount comprises a ball 525a, 529a, a ball support shaft 525a, 529b extending from each respective ball, and a ball receiving recess. Each ball is received in the respective ball recess on either the base unit 527 or the first base 530. Each ball recess surrounds the ball 525a, 529a a sufficient amount to retain the ball 525a, 529a in the respective ball recess. The first arm 524 has the second ball mount connection 529 at an end opposite the first ball mount connection 525. The second ball mount connection is received in the ball recess in the top surface 527a of the base unit 527. Extending from the ball recess is an arm accommodation depression 527b. The arm accommodation depression is recessed below the top surface 527a of the base unit 527. The arm accommodation depression allows a greater range of movement of the base unit relative to the arm.
In some embodiments, the first arm 524 may comprise a hollow portion 524a that receives the ball support shafts 525b, 529b at opposite ends. The support shafts are of a lesser diameter than the hollow portion 524a to allow a greater range of motion at the first and second ball mounts.
The first base 530 has a thumbscrew 528. The first base 530 connects to a connecting cylinder 532 which connects to an attachment base 537. In some embodiments, the first base 520 is integrally formed with the connecting cylinder 532. The first base 530 is pivotable about the axis of the cylinder 532. The thumbscrew provides compression friction to secure the first base 530 in a user selected position about the axis of the cylinder after it's been manipulated into the desired position by the user between the thumbscrew and the attachment base 537. The attachment base 537 has a lower attaching lip 534a and an upper attaching lip 534b at the bottom and top for engaging the lips 184, 187 of the front bracket portion to secure the external heads up display to the front bracket portion. In some embodiments the upper attaching lip is shorter than the lower attaching lip.
In some embodiments, the lower attaching lip 534a is drawn upward by pressing the button 535 so that lower attaching lip 543a comes out from behind lip 184 and the attachment base 537 can be removed from the front bracket portion. In some embodiments, the upper attaching lip 534b is drawn downward into the attachment base 537 by pressing the button 535 so that attaching lip 543b comes out from behind lip 187 and the attachment base 537 can be removed from the respective front bracket portion 180, 181. In some embodiments, both the upper and lower attaching lips are drawn downward and upward respectively when the button 525 is pressed to release the attachment base 527 from the front mount. The movement of either or both of the lower and upper attachment lips 534a, 534b may be achieved with the button 535 attached to a mechanism (not show) similar or identical to that used in heads up display 500 for moving the upper and lower engagement rails 510, 511 relative to each other.
Communications System The helmet assembly 100 may have a communications system 550 as shown in FIGS. 24 and 31A. The communication system 550 has a pair of ear cups 560, 570 and power wires 582, 584, data wires 583, 585, and an optional microphone 561. The power wires and data wires connect to power and data ports at the rear of the accessory-mounting rim portion. The wires are carried in the wiring conduit 580 that follows the lower back edge 262 of the accessory-mounting rim portion 200. The wiring conduit 580 may be comprised of a rubber or other flexible material. In one embodiment power and data is carried over at a single wire. In another embodiment, ear cups are battery powered and communicate wirelessly with the data source. The power and or data ports 571, 571a are located on opposite lateral sides of the ear cups. The wires have connectors 582a, 584a that are connectable to the power and/or data ports.
The ear cups 560, 570 have a padded region 562 that defines a perimeter of the ear cups and surrounds a recess portion 564. A padded region 562 may be configured to closely conform around a user's ear. The ear cups may be configured to provide ear protection against predefined decibel levels of audio sound originating outside the ear cups, such as might be created by machine operating noise, gunfire, or explosions. The recess portion 564 may comprise one or more speakers for delivering sound to a user's ear. The speakers may be connected to a communication device for communicating with other soldiers or a command center.
As the bulge of the ear coverage areas 146 is reduced in comparison with certain prior art helmets to achieve a closer conformity of the helmet with a user's head, the ear cups 560, 570 must have a lower profile in order to fit between the helmet and a user's head. Therefore the ear cups have a reduced thickness as compared with ear cups useable with certain prior art helmets. The thickness being the distance between the outermost surface of the padded region 562 and the outermost surface of the opposite side 563 of the ear cups. A microphone 561 may be mounted to one or more of the ear cups and extent a distance toward a user's mouth as shown in FIG. 31A. Alternatively, a microphone may be mounted to an inside surface of the mandible or other convenient place. Microphone wiring may be routed through the mandible to communicate with the conduit of the accessory-mounting rim portion.
Helmet Retention System A helmet retention system 600 may be used with helmet 134 as shown in FIG. 29, or other helmets, such as helmet 90 shown in FIGS. 25-27. The helmet retention system is substantially a mirror image identical across the midplane 167 of the helmet, therefore a description of one side will explain the other. The helmet retention system 600 comprises a front strap system 610 and a lower strap system 620. The front strap system 610 has a first reeling strap 616, a first contact strap 612, and a first reel 631. The lower strap system 620 has a second reeling strap 626, a second contact strap 622, and a second reel 632. The first and second reels are housed in a reel housing 630. The reel housing 630 is enclosed in a soft armor neck pad for contacting the rear of a user's neck and/or head. In another embodiment, the reel housing may comprise the accessory-mounting rim portion such as shown in FIG. 4, with a first real 633, and a second reel 634.
Referring to the front strap system 610, the first reeling strap 616 is anchored at one end 618 to the helmet at a forward location adjacent a user's temple by a front anchor 643 at both sides of the helmet. In one embodiment, the front anchor is located on the accessory-mounting rim portion 200. Whether located on the helmet or on the accessory-mounting rim portion the front anchor is generally located between a user's eye and a user's ear, such as shown in FIG. 25. A downward extending portion 616a extends downward and is fed through a loop 614 attached to the first contact strap 612 (see FIG. 26B). After the loop 614, an upward extending portion 616b extends upward from the loop adjacent to, and in some versions substantially parallel to, the downward extending portion 616a until the first reeling strap reaches a first front system block 641. The first reeling strap 616 slides over the first block 641 and thereafter the first reeling strap extends rearward along a rearward extending portion 616c toward the rear of the helmet on a slightly declining angle to second front system block 642. The reeling strap 616 slides over the second block 642 and downward and forward to a third block 645 then rearward to the reel housing 630 and then to the first reel 631 with a reeling strap portion 616d.
The reels 631,632 are substantially the same and an exemplary reel indicated 631, 632 is shown in FIG. 26A. Both reels 631, 632 comprise a center hub 636 about which each reel spins. Both reels 631, 632 are circular and have a channel 635 defined by the outer disk walls 637, 638. The channel is for reeling, holding, and releasing the respective reeling straps 616, 626.
In one embodiment, the reel 631 may also include an anchor or fixation where a reeling strap is held at some place along a length of the reeling strap that is not an end of the reeling strap. The reeling strap 616 can be anchored at a midpoint along its length in the reel, where the length includes the reeling strap 616 on both sides of the helmet. Turning the reel 631 in a first direction draws both portions 616d, 616e of the reeling straps 616 located on opposite sides of the helmet into the reel and thereby increase the tension on the reeling strap 616 on both sides of the helmet and the associated contact straps 612, by raising the loops 614 on both sides of the helmet. Turning the reel in a second direction, opposite of the first direction, will spool out the reeling strap portions 616d, 616e in both direction and thereby release tension on the reeling straps 616 on both sides of the helmet and release tension on the contact straps 612 by lowering the loops 614 on both sides of the helmet.
As the reeling strap enters the reel 631 with reeling strap portion 616d, it can be anchored to the real as just described, and/or just wound around the reel a predetermined number of turns, and may be further/or lesser wound around the reel a number of times depending on the desired rotary position of the reel. The reeling strap portion 616e will extend out of the reel along to the opposite side of the helmet as shown in FIG. 26A. The reeling strap portion 616e is wound on the reel 631 in similar fashion in a same rotary direction. On the opposite side of the helmet, the reeling strap 616 continues from the strap portion 616e in a configuration mirror image identical to that shown in FIG. 25 and the reeling strap end is anchored in place in a mirror image identical location opposite that shown in FIG. 25. Therefore, opposite ends of the reeling strap 616 are anchored to the helmet in opposite front temple areas of the helmet or accessory-mounting rim portion. Likewise, the first contact strap 612 continues under a user's chin as shown in FIG. 25 to engage the first reeling strap 616 at a loop 614 on the opposite side of the helmet.
The front strap system 610 is configured to increase or decrease the downward tension in a forward area between a helmet 10 and the user's head. Turning the first reel will move the reeling strap 616 and the position of the loops 614 to move up or down in the direction H shown in FIG. 25 depending on the direction that the first reel 631 is turned.
The lower strap system 620 operates similar to that of the front strap system 610 but the lower strap system 620 is positioned differently than the front strap system. The second reeling strap 626 is anchored at one end 628 at a rear position of the helmet by a rear anchor 644. The anchor 644 may be positioned on the helmet behind the rear of a user's head when viewed from the side as shown in FIG. 25. In one embodiment, the anchor 644 is located on the accessory-mounting rim portion in an area on or near the lower back edge 262. The second reeling strap 626 extends from the anchor 644 downward along a downward extending portion 626a and forward to a first lower system block 646. The first block may be on the helmet, on the accessory-mounting rim portion, on the reel housing. The second reeling strap 626 then extends forward toward a users ear, on a forward portion 626b to a loop 624 attached to the second contact strap 622. The second reeling strap 626 loops back around loop 624 (see FIG. 26B) and extends rearward along rearward portions 626c, 626d to the second reel 632. The rearward portion 626c travel adjacent, and some configurations, substantially parallel to the forward portion 626b.
As the second reeling strap 626 enters the reel 632 with strap portion 626d, it can be anchored or fixed to the reel at some place along its length, and/or just wound around the reel a predetermined number of turns, and may be further/or lesser wound around the reel a number of times depending on the desired position of the reel, and reeling strap portion 626e will extend out of the reel along to the opposite side of the helmet as shown in FIG. 26A. On the opposite side of the helmet, the reeling strap 626 continues in a configuration mirror image identical to that shown in FIG. 25 and the reeling strap end is anchored in place to an anchor 644 in a mirror image identical location opposite that shown in FIG. 25. The reeling strap portion 626e is wound on the reel 632 in similar fashion in a same rotary direction. On the opposite side of the helmet, the reeling strap 626 continues from the strap portion 626e in a configuration mirror image identical to that shown in FIG. 25.
Therefore, opposite ends of the reeling strap are anchored to the helmet in opposite rear areas of the helmet. Likewise the second contact strap 622 is configured to continue over the front of a user's chin as shown in FIG. 25 to engage the second reeling strap 626 at a loop 624 on both, opposite sides of the helmet. The open area chin cup 621 configuration provided by the first contact strap 612 and the second contact strap 622 and the gap therebetween below the contact or cross point 611 secures the contact with the users chin while leaving an open area of the users chin for a more comfortable fit. Further, the open configuration in the chin area does not interfere with weapons sighting and is accessible with the visor deployed and/or the mandible deployed.
The lower strap system 620 is configured to increase or decrease the downward tension in a rear area between a helmet 90 and the user's head.
The reeling strap 626 can be anchored at a midpoint along its length in the reel 632, where the length includes the reeling strap 626 on both sides of the helmet. Turning the reel 632 in a first direction draws both portions 626d, 626e of the reeling straps 626 located on opposite sides of the helmet into the reel 632 and thereby increase the tension on the reeling strap 626 on both sides of the helmet and the associated contact straps 622, by moving rearward the loops 624 along the direction I on opposite sides of the helmet. Turning the reel in a second direction, opposite of the first direction, will spool out the reeling strap portions 626d, 626e in both direction and thereby release tension on the reeling straps 626 on both sides of the helmet and release tension on the contact straps 622 by moving forward the loops 624 along the direction I on both sides of the helmet.
Each of the front strap system 610 and the lower strap system 620 are adjustable by turning the corresponding reels 631, 632. Therefore the helmet retention system 600 may be adjusted by a user using only one hand. This is an improvement over the prior art systems that require several buckles where the strap may be threaded and adjusted their through. Some prior art retention systems have as many as five buckles or points of adjustment for adjusting the various straps use to secure the helmet to a user's head.
In one embodiment, the contact straps 612, 622 may be divided as shown in FIG. 27 to provide for a detachable chin contact portion 650. In this arrangement portions of the contact straps may disconnect from one another on opposite lateral side of a user's face. The chin contact portion 650 has a lower chin contact strap 612g and a front chin contact strap 622g. The lower strap 612g and the front strap 622g join at a first junction 653 the end of which has a loop that engaged a male portion 662 of a buckle. The male portion 662 is releasably engageable with a female portion 660 of the buckle. A lower left side portion 612f of the first contact strap 612 joins with a forward left side portion 622f of the second contact strap 622 at a second junction 664. The second junction 664 attaches to the female portion 660 of the buckle. In one embodiment, a substantially mirror image identical buckle is used on the right side of the user's face, so that the chin contact portion 650 may be released from either side. In another embodiment, a buckle is only provided on one side and the contact straps extend to connect at the buckle and are joined thereby.
The connection of the reeling straps to the contact straps may be covered by sleeves 613, 623 as shown in FIG. 27 to prevent chaffing or irritation of a user's skin by the movement of the reeling straps or the contact straps and the loop 614, 624. Further, other portions of the reeling straps may be covered by a sleeve or may be contained in a conduit to prevent user contact with the reeling straps.
Mask The helmet assembly 100 may be used with a mask 680 as shown in FIG. 29. The front inside surfaces of the helmet positively contact the top of the mask, providing stability. The inside surface contact may include contact with helmet padding. The open area chin cup 621 is compressed so that both the contact straps extend under the chin. The mask may have one or more lenses 682 allowing a user to see through. The mask extends rearward to a back edge 681. The mask may protect against chemical, biological, nuclear, and/or radiological exposure or threats. Mask may be used with or without a balaclava 690 for covering the whole head of a user exposing only part of the face, which may be covered by a mask. The balaclava may protect against chemical, biological, nuclear, and/or radiological exposure or threats.
Goggle Attachment System The helmet assembly 100 may have a goggle attachment system 700 shown in FIGS. 30, 31A-31D to secure protective goggles 695 with a protective lens 695a to a user's face. The goggles may be those made commercially available by Revision Military Ltd. of Vermont and known as DESERT LOCUST goggles, ASIAN LOCUST goggles, WOLFSPIDER goggles, or BULLET ANT goggles. The goggle attachment system 700 has an anchor tower 710 with goggle clip receivers 702, 704 on opposite lateral sides of the anchor tower. The goggle clip receivers 702, 704 each have a slot 701 to receiving a goggle clip 720. The anchor tower 710 may include a battery such as contained in battery pack 305 and therefore the anchor tower may be used in place of battery pack 305. The anchor tower 710 when used with the helmet and/or accessory-mounting rim portion will be positioned along the midplane 167 of the helmet at the rear as shown in FIG. 31E. The anchor tower 710 includes the snap-in tab or securing connection 302 and the catch strip 304 as previously described for attaching the rear tower of FIG. 14C. Thus, the tower is captured at its lowest end by the tab 302 into the accessory-mounting rim portion and prevented from vertical dislodgement by the catch strip 304 being held horizontally by the claws 115a, 115b of the top mount 115 and prevented from vertical movement by shoulders 710a of the tower abutting a bottom of the mount 115.
The clip 720 has a peripheral edge 728 surrounding a flexing portion 723. The flexing portion is connected to the peripheral edge by a bridge 729. The peripheral edge has a step 728c, an inset portion 728a, and a raised portion 728b. The raised portion 728b is closer to the strap loop opening 725 than the inset portion. The inset portion is adjacent the bridge 729. The raised portion 728b connects to a loop bar 724 that defines a portion of the strap loop opening 725. A goggle strap 696 or other eyewear or accessories strap may be secured around the strap loop opening 725. The oppose end of the goggle strap may be attached to a goggle as shown in FIG. 31A. There is a gap 721 on three sides of the flexing portion between the flexing portion and the peripheral edge.
The flexing portion 723 has a first portion 727 separated by a recess 726 from a second portion 722. The boundary 726a between the recess 726 and the second portion 722 is substantially coplanar with the step 728c. The first portion 727 rises or slopes rearward (out of the page of FIG. 31D) from the bridge 729 towards the recess 726. The second portion 722 rises or slopes rearward (out of the page of FIG. 31D) from an end 722a opposite the bridge, toward the recess 726. The first portion rises (out of the page of FIG. 31D) more aggressively than the second portion. The second portion 722 rises to a more outward position (out of the page of FIG. 31D) than the most outward position (out of the page of FIG. 31D) of the first portion 727.
The front face (with respect to the front direction of the helmet) of the clips 718 and anchor tower 710 are shown in FIG. 31C. The front peripheral edge surface 730 is substantially flat. The front surface of the bridge portion 739 is substantially flat. A step 738 is located where the bridge portion connects with the flexing portion 723 on the front side of the clip. Therefore, the flexing portion 723 is positioned more rearward (into the page of FIG. 31C, out of the page of FIG. 31D) than the bridge portion on the front side of the clip and the step 738 provides the connection. The flexing portion 723 has a default position which is more rearward (extending into the page of FIG. 31C, out of the page of FIG. 31D) than the front peripheral edge surface 730. This configuration allows the flexing portion 723 to flex forward (out of the page of FIG. 31C, into the page of FIGS. 31D and 31B) as the clip is pressed into the clip receiver.
Only one of the goggle clip receivers 702, 704 will be described as they are mirror image identical across the midplane 167. The slot 703 has peripheral engagement surface 707a continuous with an end engagement surface 707 and an entry raised portion 708. The entry raised portion 708 extends forward from one side off the slot 703. The entry raised portion 708 is sized and shaped to fit into the recess 726 of the clip 720. It can be a rectangular block shape. The peripheral engagement surface 707a, the end engagement surface 707, and the side raised portion 708 surround a recessed portion 705. The peripheral engagement surfaces 707a are configured to contact the inset peripheral edge portion 728a of the goggle clip.
As the clip is inserted into the slot of the clip receiver, the first portion 727 contacts the entry raised portion 708 of the clip receiver. As the clip is further inserted into the slot 703, the entry raised portion 708 of the clip receiver forces the flexing portion 723 of the clip forward (into the page of FIGS. 31B and 31D) as the first portion 727 continues contact with the entry raised portion 708. The flexing portion 723 of the clip continues to be pushed forward to the point where the recess 726 of the clip registers with the entry raised portion 708. When this occurs, the entry raised portion 708 is received in the recess 726 and secures the clip in the clip receiver as this spring force of the flexing portion 723 pushes the recess 726 rearward (out of the page of FIGS. 31B and 31D) to capture the entry raised portion 708. In this configuration, the entry raised portion is secure between the first portion 727 of the clip and the second portion 722 of the clip. In addition, when the clip is secured in the clip receiver, the entry raised portion 708 of the clip receiver is located in the recess 726, the step 728c of the clip is engaged against, or in close proximity to a face 701a of clip receiver.
To release the clip from the clip receiver, the second portion 722 of the flexing portion of the clip is pressed forward (into the page FIG. 31D) by a user to release the entry raised portion 708 of the clip receiver from the recess 726 of the clip. The forward pressure continues until the rear most portion (out of the page FIG. 31D) of the first portion 727 is depressed forward (into the page FIG. 31D) of the entry raised portion 708 of the clip receiver. Once the first portion 727 is depressed forward of the side 709 of the entry raised portion 708 of the clip receiver, the clip can be withdrawn laterally from the clip receiver.
Face Shield and Mounting Arrangement The details of the face shields 38, 138 and the mounting arrangement 142 are shown in FIGS. 32-46. FIGS. 33, 35-38, and 38B show the mounting arrangement 142 used on mount 44 which is attached or attachable to helmet 34 as provided in U.S. patent application Ser. No. 12/875,106, filed Sep. 2, 2010. However, mounting arrangement 142 is adapted to attach and readily attachable to the front mount 144. Further, FIGS. 33, 34, 36-38, 38B, 38C, and 40-43 show the mounting arrangement 142 used with face shield 38 having a frame 95 and a lens 94. However, the face shield 38 can be replaced by face shield 138 having frame 101 and attached to the mounting arrangement 142 so that the frame may be held against or in close proximity to the front top brim of the accessory-mounting rim portion 200 and may hold the lens 102 adjacent thereto. The mounting arrangement 42 of U.S. patent application Ser. No. 12/875,106, filed Sep. 2, 2010, is substantially the same as mounting arrangement 142.
FIG. 32 shows the mounting arrangement 142 and the lens 102 attached to front mount 144 and in a raised standby position above the user's eyes. The frame 101 for attaching with arms 1114a, 1114b is not shown.
In one embodiment, the face shield 38 comprises a lens 94 and a frame 95. In another embodiment, the face shield 138 comprises lens 102 and frame 101 as shown in FIG. 39. The lens 94 fits within a groove 97 (FIG. 34) in the frame 95 and is fixed to the frame by three screws 96 (FIG. 33).
The lens 102 fits within a groove 1197 (FIG. 39) in the frame 101 and is fixed to the frame by via three holes 1196 where screws (not shown) may be provided. For military use particularly, the face shield lens 94, 102 should be ballistic impact resistant. It can be of a laminated construction and can feature a variable light transmission system. Such a variable light transmission system can incorporate an electronic control system to vary the light transmission according to the ambient light conditions.
The face shield frame 95 is mounted to the mounting arrangement 142 via the shield mount 43. The shield mount 43 comprises parallel lugs 98a, 98b (FIG. 38). The lugs 98a, 98b include holes 99a, 99b for receiving pins 99c (only one shown, FIG. 38). Each pins 99c passes through a hole 1101 (FIG. 37) formed through sides in a base portion 1102 (FIG. 36) of a lever 1100, and are held in place by the head of the pin and a circlip or lock washer 99d. The lever 1100 includes a hole 1103 (FIG. 36) through a distal end thereof. A pivot pin 1107 (FIG. 37) is fit though the hole 1103 and is fixed to sidewalls 1110a, 1110b (FIG. 38) which extend outward from a baseplate 1112. L-shaped side links 1114a, 1114b are pinned at one end to the lugs 1110a, 1110b and at an opposite end to the lugs 98a, 98b.
Face shield frame 101 is mounted to arrangement 142 via the shield mount 142e in a substantially similar manner to the configuration mounting the shield frame 95 to the mounting arrangement 142 via the shield mount 43. The shield mount 142e comprises parallel lugs 98a, 98b (FIG. 38). The lugs 1198a, 1198b include holes 1199a, 1199b for receiving pins 1199c (only one shown, FIG. 38). Each pins 99c passes through a hole 1101 (FIG. 37) formed through sides in a base portion 1102 (FIG. 36) of a lever 1100, and are held in place by the head of the pin and a circlip or lock washer 99d.
The lever 1100 has a central recess 1116 (FIGS. 36 and 37). An opening 1118 is provided within the central recess 1116. A hook-shaped latch 1122 (FIGS. 36, 37 and 38) has a base end pivotally attached to the sidewalls 1110a, 1110b by a through pin 1124 (FIG. 37). The latch extends outwardly through the opening 1118. The latch is biased to rotate upward to a latched position by a torsion spring 1130 (FIG. 38). When the face shield is moved from the upward, non-use or standby position down to the deployed position as shown in FIG. 1, the lever slides over the angular face 1122a of the latch, which causes rotation of the latch downward as the hook end passes through the opening 1118. Once the hook end of the latch is through the opening 1118, the latch rebounds by the urging of the torsion spring to rotate upward and the hook end overlies a first recessed surface 1116a of the lever adjacent to the opening 1118. The latch 1122 holds the lever 1100 and the face shield 38, 138 in the deployed position. The latch 1122 can also be made to overlie a second recessed surface 1116b to hold the face shield in a slightly open position with respect to the helmet and mandible. To move the face shield 38, 138 to the slightly open position or the tilted up, non-use position, the hook end 1122a of the latch must be depressed downward by a finger to release the latch from the lever and the face shield can be pivoted upward.
The pivot pin 1107 is fixed to the sidewalls 1110a, 1110b by use of a threaded screw 1123a and a spring pin 1123b on each end of the pivot pin 1107 for each sidewall 1110a, 1110b. The spring pin 1123b is a pin having a portion that is larger than a hole in the pivot pin 1107 such that it must be resiliently or deformable forced into the hole to hold the pivot pin 1107 fixedly to the sidewalls 1110a, 1110b. The use of a spring pin prevents unscrewing of the screw 1123a due to the repetitive raising and lowering of the face shield.
The pivot pin 1107 includes two recesses 1126a, 1126b at two spaced apart, circumferential positions. A detent mechanism 1127 is shown in FIGS. 41 and 43. The detent mechanism includes three spring mechanisms 1127a arranged in parallel. Each mechanism includes a compression spring 1127b that urges a ball 1127c toward the pivot pin 1107. All the compression springs are braced by a backing through pin 1127d. The compression spring 1127b and the ball 1127c are captured within a cylindrical passage 1100a formed in the lever 1100, by the backing pin 1127d and the pivot pin 1107. When installed, the springs 1127b are pre-compressed between the backing pin 1127d and the pivot pin 1107 to the degree necessary to allow the balls 1127c to be urged into the appropriate recess 1126a, 1126b when the recess presents itself to the balls 1127c upon rotation of the lever 1100 with respect to the pivot pin 1107. The balls 1127c fit into the recess 1126a when the face shield is moved slightly away from the helmet and mandible to allow for increased ventilation, and fit into the recess 1126b when the face shield 38, 138 is pivoted into the raised, non-use position (FIGS. 32). The engagement between the detent mechanism 1127 and either of the recesses 1126a, 1126b provides a resilient hold that can be overcome by force from the wearers hand to pivot the face shield.
The face shield is operable with one hand to raise and lower the face shield. One finger depresses the latch 1122 as the rest of the hand lifts the face shield to a raised position. The face shield can be lowered with one hand and the latch is self engaging.
FIG. 38B shows the baseplate 1112 includes a main body portion 1132, a backing plate 1133 (FIG. 38A), a spring 1134, and a latching tongue 1136. The main body portion 1132 includes an upper edge 1138 (FIGS. 34 and 37). The spring 1134 biases the latching tongue 1136 in a direction away from the upper edge 1138. A handle 1140 is connected to the latching tongue through a side clearance within the main body portion 1132.
The backing plate 1133 is a metal piece and includes side walls 1133a having holes 1133b which allow resin of the main body portion 1132 to flow through the holes during overmolding to integrate the backing plate 1133 with the main body portion 1132. The mount 144 includes a top front formation or central accessory mount 1144 (FIG. 35) that includes an inverted U-shaped retainer portion 1148, surface depressions 1150, 1152, 1154, 1156, 1158, a top slot 1160 and a bottom slot 1162. The surface depressions 1150-1158 are sized and shaped to receive protrusions 1163, 1164, 1165, 1166 (FIG. 34) on a back of the baseplate 1112.
The front mount 144 includes a top formation or central accessory mount 144a that includes an inverted U-shaped retainer portion 144b. The top formation 144a may have surface depressions, a top slot, and a bottom slot (not shown) such as surface depressions 1150-1158, a top slot 1160 and a bottom slot 1162 of mount 144. The surface depressions may be sized and shaped to receive protrusions 1163, 1164, 1165, 1166 (FIG. 34) on a back of the baseplate 1112. The baseplate 1112 may be supported on ledge 144c. In one embodiment the ledge 144c may be a latch that is resiliently biased upward to secure the base plate in the retainer portion 144b. The ledge 144c may have a lip to prevent the forward movement of the base plate 1114.
The front mount is also compatible to mount a night vision appliance or night vision goggle.The front mount or front bracket portions are mounted on a helmet 34 using screws 1360, 1362 and a center screw 1363 (FIG. 35).
To mount the baseplate 1112 to and into the formation 1144, the upper edge 1138 is fit into the top slot 1160, the baseplate is fit snugly within the retainer portion 1148 and the tongue 1136 is retracted upwardly by force on the handle 1140 until the tongue can be fit into the bottom slot 1162.
Similarly, to mount baseplate 1112 to and into front mount 144, the upper edge 1138 into the top slot 144d, the baseplate is fit snugly within the retainer portion 144b and the tongue 1136 is retracted upwardly by force on the handle 1140 until the tongue can be fit into the bottom slot, or secured on the ledge 144c.
The face shield frame 95 can also incorporate a removable gasket to seal against the helmet brim to prevent ingress of fluids.
FIG. 34 shows the frame 95 includes frame supports 95a that brace against the helmet gasket 240 when the face shield is properly seated. FIGS. 3 and 39 show a contact gasket 101a that seals the contact between the frame 101 and the accessory-mounting rim portion such as an accessory-mounting rim portion, such as a halo 200. The gasket 101a has a first lip 101b that crosses a second lip 101c of the gasket at it approaches the lateral edges of the frame 101.
From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific apparatus illustrated herein is intended or should be inferred.
