A ballistic garment (10) including tensioned body panels (12, 22, 32 and 38) to resist successive ballistic impacts.
This application claims priority to U.S. Provisional Patent Application Ser. No. 60/565,148, filed Apr. 26, 2004, the disclosure of which is expressly incorporated by reference herein.
BACKGROUND AND SUMMARY OF THE INVENTIONThe present invention relates to ballistic garments and, more particularly, to a ballistic vest having improved resistance to successive ballistic impacts.
Ballistic garments, such as vests including multi-layered ballistic or body armor panels are well-known in the art. Moreover, such ballistic vests are typically formed of independent body armor panels that are received within a fabric pouch or carrier. Upon being impacted by ballistic projectiles, the panels function independently deforming within the individual carriers. Such deformation causes the panels to lose their shape and may create openings or gaps in the areas between the panels, resulting in increased vulnerability to secondary projectiles. The independent functioning of the panels increases the thickness and stiffness required to stop projectiles. Depending upon the duty design or anticipated threat, the panels may have various amounts of overlap to compensate for edge deficiencies and to stop ballistic rounds fired at the wearer. In such conventional body armor panels received within carriers, fasteners may extend from the carrier to assist in maintaining an overlapping arrangement.
Conventional body armor panels located in carriers may float or move on the chest and the back of the wearer. Such panels, while usually successful in resisting initial impact from a ballistic projectile, tend to displace inwardly at the point of impact. Moreover, each panel tends to function independently, exhibiting substantial back face deformation (or rearward travel into the body of the wearer) in response to impact. Given successive ballistic impacts, there is gradual shrinkage of the coverage of the panel. As such, successive impacts reduce the protection of the garment by reducing the area of coverage. Consequently, the ability to resist multiple impacts without exposing additional body area has become an increasing concern.
As noted above, one proposed solution has been to provide a substantial overlap between body armor panels on severe duty tactical vests to account for this deficiency. This adds significant extra weight and expense to the vest, and the design is still not optimized to absorb the forces of striking projectiles. While it has also been proposed to place the body armor panels in tension through the use of elastic bands, such a design relies upon securement to an outer carrier. Further, the elastic bands do not provide a given degree of certainty with respect to applying tension within the panels.
According to an illustrative embodiment of the present invention, a ballistic resistant garment for protecting a wearer from penetration by a projectile includes a back panel configured to cover the width of the back and extending from the shoulders to the waist of a wearer. A front panel is configured to cover the width of the chest and extends from the shoulders to the waist of a wearer. A first side panel couples the back panel to the front panel and is configured to cover a first side of the wearer from the axilla to the waist. The back panel, the front panel, and the first side panel are formed from ballistic material configured to resist penetration therethrough by a projectile. The first side panel is directly coupled to the back panel and the front panel, such that the back panel, the front panel, and the first side panel are configured to be in tension around the body of the wearer and return substantially to an original shape after an impact from a projectile.
According to a further illustrative embodiment of the present invention, a ballistic resistant garment for protecting a wearer from penetration by a projectile includes a back panel configured to cover the width of the back and extending from the shoulders to the waist of a wearer. A front panel is configured to cover the width of the chest and extends from the shoulders to the waist of a wearer. A connecting panel couples the back panel and the front panel. The back panel, the front panel, and the connecting panel are formed of multiple layers of ballistic resistant material. The ballistic resistant material of the connecting panel includes an inner layer and an outer layer, wherein the inner layer has a length shorter than the outer layer.
According to yet another illustrative embodiment of the present invention, a ballistic resistant garment for protecting a wearer from penetration by a projectile includes a back panel of ballistic resistant material, the back panel including a front face and a back face. The garment further includes a front panel of ballistic resistant material, the front panel including a front face and a back face. A coupler includes a body having a first end rigidly coupled to move with the back panel and a second end rigidly coupled to move with the front panel. The coupler is configured to tension the back panel and the front panel such that each of the back panel and the front panel resist back face deformation in response to impact from a projectile.
According to a further illustrative embodiment of the present invention, a ballistic resistant garment includes a panel formed of ballistic resistant material, and a coupler connected to the panel and including a body having a first end and an opposing second end. The body includes a resilient portion and a substantially rigid portion wherein the resilient portion is configured to permit the body to stretch, and the rigid portion is configured to prevent the body from stretching more than a predetermined length defined between the first end and the second end.
According to another illustrative embodiment of the present invention, a ballistic resistant garment includes a back panel, a front panel, and a connecting panel coupling the back panel to the front panel. The back panel, the front panel, and the connecting panel are formed from a ballistic material. The back panel, the front panel, and the connecting panel are coupled together through at least one of a continuous sheet of ballistic resistant material, a rigid coupler, and a limited travel coupler such that the back panel, the front panel, and the connecting panel are in tension around the body of the wearer for limiting shrinkage of the impacted panel during initial and subsequent strikes.
Additional features and advantages of the present invention will become apparent to those skilled in the art upon consideration of the following detailed description of the illustrative embodiment exemplifying the best mode of carrying out the invention as presently perceived.
BRIEF DESCRIPTION OF THE DRAWINGSThe detailed description of the drawings particularly refers to the accompanying figures in which:
Referring initially to
A first, or left, side panel 32 couples the back panel 12 to the front panel 22 and is configured to cover a first, or left, side 34 of the wearer 16 from the axilla 36 to the waist 20. Similarly, a second, or right, side panel 38, couples the back panel 12 to the front panel 22 and is configured to cover a second, or right, side 40 of the wearer 16 from the axilla 36 to the waist 20.
In the illustrative embodiment of
As shown in
Further, each of the panels 12, 22, 32, and 38 includes a front face 52 and a back face 53. Tension within the panels 12, 22, 32, and 38 causes resistance to back face 53 deformation in response to impact from a projectile, thereby reducing localized blunt force trauma and improving performance of the vest 10 in response to the initial and subsequent strikes. More particularly, the tension in the vest 10, by reducing back face deformation, facilitates the ballistic panels 12, 22, 32, and 38 remaining in an original protective position if additional impacts are applied. The tension in the vest 10 limits the shrinkage in the impacted panel 12, 22, 32, 38 during initial and successive strikes, thereby preventing substantial reduction in the area of protective coverage.
In one illustrative embodiment, the shoulder portions 26, 28 and side panels 32, 38 may be of reduced thickness relative to the back panel 12 and the front panel 22. In other words, the number of layers 44 of ballistic material 42 may be less in the shoulder portions 26, 28 and the side panels 32, 38 than in the back panel 12 and the front panel 22. Illustratively, one-half of the layers 44 could extend from the waist 20 over the shoulders 18 of the wearer 16, and one-half of the layers 44 could extend circumferentially around the waist 20 of the wearer. These respective “half layers” 44 could then be secured together, for example by quilt stitching, such that full number of layers 44 are positioned within the back panel 12 and the front panel 22, and half the number of layers 44 are positioned within the shoulder portions 26, 28 and the side panels 32, 38. However, the layers 44 together still define at least one continuous sheet of ballistic material defining the entire vest 10.
Referring now to
Illustratively, the position of the adjustable second side panel 54 on the left side 34 or the right side 40 of the wearer 16 is determined based upon the well-known “Weaver stance”, as illustrated in
As with the ballistic vest 10 of
Referring now to
The couplers 60 may be connected to the layers 44 in a variety of manners. Illustratively, the opposing ends 66 and 68 of the coupler 60 may be secured directly to the layers 44 through stitches 70 and 72. Alternatively, as shown in
In the further illustrative embodiment coupler 60′ as shown in
Other types of fasteners may also be used in place of couplers 60, such as hooks and eyes, or hooks and grommets. It is also envisioned that the two adjoining panels may be permanently coupled by means of D-rings, cam clamps, slide adjusters or similar means. A slide adjuster with a quick release could be utilized to remove the vest and a pull strap to adjust it when first placed on the wearer 16. Depending upon the width of the strap, it may be necessary to use more than one per side or other opening to provide a solid connection and keep the panels continuously supported and from deforming if challenged.
In a further illustrative embodiment, each panel 12, 22 may be restrained from movement relative to its respective carrier 46, and the respective ends 66, 68 of the coupler 60 rigidly and directly secured to the carrier 46. For example, a rough surfaced outer layer 48 and inner layer 50 of the carrier 46 may frictionally restrain the panel 12, 22 from movement relative thereto. Further, conventional fasteners, such as a hook and loop fastener, may be fixed inside of the carrier 46 and operably couple with the panel 12, 22 to prevent such relative movement.
It is envisioned that the edge reinforcement members as detailed in U.S. patent application Ser. No. 10/625,417, filed Jul. 23, 2003, which is expressly incorporated by reference herein, may be utilized in connection with the vests 10, 10′, and 10″ of the present invention. The edge reinforcement members may comprise cords formed of ballistic resistant material secured to the peripheral edges of the vest 10, 10′, 10″ through conventional securing means, such as stitches. Using such edge reinforcement members would illustratively facilitate stitching through just enough layers 44 of ballistic material to provide the connective strength required. The edge reinforcement members would join all the layers 44 together, thereby holding the layers 44 of panels in alignment. Additionally, the couplers 60 may be attached directly to the edge reinforcement members or its securing means which, in turn, are rigidly secured to the respective panel 12, 22, 32, 38.
With further reference to
With reference to
In one illustrative embodiment, the body 64 of the coupler 60 includes a resilient portion 94 and a substantially rigid portion 96, the substantially rigid portion 96 being configured to limit the movement of the second end 68 relative to the first end 66. The substantially rigid portion 96 of the body 64 is embedded within the resilient portion 94. The resilient portion 94 may be composed of a gathered layer of fabric that has an elastic give that is limited by the rigid portion 96 when the fabric is stretched tight. The rigid portion 96 may comprise a relatively inflexible fabric. If the vest 10′ is challenged and the elastic gives until the surrounding fabric is drawn tight, the fabric then provides the solid connection desired. In one illustrative embodiment, the resilient portion 94 may be made with a true elastic or spandex that has a restraining fiber sewn, woven, knit or otherwise integrated therein, which defines the rigid portion 96. In one illustrative embodiment, this restraining fiber may be sewn in a zig-zag stitch that becomes straight as the elastic is stretched, thereby creating the solid rigid connection of limiting the travel of the panels.
With reference now to the further illustrative embodiment vest 100 of
As shown in
As with the shoulder portions 26 and 28, the layers 44 extending between the back panel 12 and the front panel 22 are configured to account for the increased travel distance around the torso 51 for the outer layers compared to the inner layers. More particularly, the length of the outer layer 44d from the back panel 12 to the front panel 22 may be greater than the length of the inner layer 44a from the back panel 12 to the front panel 22 so that the panels 12 and 22 align properly.
As may be appreciated, the present invention is configured to prevent relative movement between adjacent ballistic panels, thereby effectively creating a single panel comprising the entire vest. Semi-rigid couplers may be provided to provide some flexibility in sizing and limited movement to accommodate the filling and expelling of the lungs and other movement of the wearer. The semi-rigid couplers permit the vest to act as a single sheet of ballistic material under certain conditions (particularly when challenged by ballistic projectiles, sharp edged weapons, etc.). Such an effective continuous design reduces or eliminates gaps between adjacent panels, thereby saving weight, increasing comfort, and reducing cost of production while providing improved protection.
While the illustrative embodiment vests 10, 10′, 10″ have been detailed for use with ballistic projectiles, such as bullets, it should be appreciated that they may find equal applicability in protecting a wearer from other threats. The reduction of back face deformation, limitation of shrinkage, and shape return by the panels are benefits in a wide variety of uses. For example, the vests 10, 10′, 10″ may be used to protect against strikes from high speed shrapnel, explosive forces, and sharp edged objects, such as knives. Further, the vests 10, 10′, 10″ may be used to reduce intrusive injury to internal organs by point loads, such as handlebars (by motorcycle riders) and bullhorns (by bull riders).
