SHOULDER PADS INCORPORATING CERVICAL SPINE PROTECTION DEVICE

Abstract

Shoulder pad includes shoulder pads and a cervical spine protection device. The device includes an upper portion for engagement with a helmet when an axial force is applied to a portion of the helmet. The upper portion has a front section, a rear section, and side sections which have a top surface. At least one damper element is provided within the device. The top surface of the side sections has an apex higher than the top surface of the front section and the rear section when the device is worn. The axial force applied to the helmet is absorbed by the device and directed away from a cervical spinal column of the user by the device. The damper element, when the axial force is absorbed by the device, resistively collapses to attenuate the axial force. The device allows extension of the head and neck during athletic movement.

FIELD OF THE INVENTION

The present invention relates generally to shoulder pads incorporating a protective gear for use in conjunction with contact sports and more particularly to shoulder pads incorporating cervical spine protection device that minimizes damage to the spinal column and spinal cord while allowing substantially unrestricted movement of the head and neck during athletic activity.

The present invention can be used with athletic equipment in a number of different sports. However, due to the increased focus on head trauma, concussions, and cervical spine injuries in football, the present invention's application is particularly focused on its use with football shoulder pads. The inventor, Dr. Patrick Kerr, played high school and college football, and as a licensed Chiropractic, understands the impacts of these sports on a person's body. In addition to the two patents that Dr. Kerr has already received on embodiments of the present invention as described in U.S. Pat. Nos. 8,615,819 and 8,370,968, Dr. Kerr continues to research and develop additional means to improve the Kerr Collar, a protective device used by football players to minimize damage to the spinal column and spinal cord while allowing substantially unrestricted movement of the head and neck during athletic activity. More information about Dr. Kerr and the Kerr Collar can be found on his website at http://doctorkerr.net/.

BACKGROUND OF THE INVENTION

Injuries to the neck are some of the most serious injuries in contact sports. For example, hyperextension of the neck to the rear can cause permanent damage to the spinal cord and can result in paraplegia, quadriplegia, and/or other forms of paralysis. If the neck is bent excessively to one side, the nerves in the brachial plexus can be stretched to cause what is commonly known as a “pinched nerve.” In severe cases, excessive lateral cervical flexion can cause permanent and irreparable damage to the nerves of the brachial plexus. Furthermore, undue flexing of the neck at an angle to the rear and to one side can result in equally serious damage to the cervical spine, brachial plexus, and/or adjacent areas of the neck and upper back.

The most serious of injuries may occur during an axial loading, when the head is driven down toward the neck and shoulders producing an excessive pressure that the cervical spine cannot handle. This pressure causes a buckling of the spinal column and may lead to disc herniation, muscle and ligament damage, and potentially spinal cord injury.

While neck injuries have been recognized as a serious problem in contact sports, very little progress has been made in developing protective athletic equipment that protects the athlete's neck without restricting their normal movement.

Existing shoulder pads were designed to protect the shoulder area of players in contact sports. The shoulder pads of the future will provide protection to the neck area as well as the shoulders. Existing shoulder pads leave an opening around the neck area which puts players at risk for cervical injury, paralysis or death. Because of the bio-mechanics of the head, neck and torso we can use shoulder pads to provide protection for the neck. An embodiment of the present invention seeks to build shoulder pads from the neck area downward and outward to the shoulders.

A number of prior art devices have been designed to reduce injuries to the necks of players in contact sports. These devices include U.S. Pat. No. 3,189,917 to Sims, U.S. Pat. No. 3,497,872 to Mitchell, U.S. Pat. No. 4,094,015 to Howard, U.S. Pat. No. 4,338,685 to LaPorta, U.S. Pat. Nos. 4,821,339 and 4,996,720 to Fair, U.S. Pat. No. 5,404,590 to Monica, U.S. Pat. No. 5,546,601 to Abeyta, U.S. Pat. No. 6,058,517 to Hartunian, and U.S. Pat. No. 6,874,170 to Aaron. In addition, U.S. Pat. No. 8,549,674 to Kraemer et al. provides specific details with respect to a shoulder pad used in a contact sport such as football, hockey, or lacrosse. It is envisioned that the aspects of the present invention would be used with a typical shoulder pad as described in U.S. Pat. No. 8,549,674, the Background of the Invention in U.S. Pat. No. 8,549,674, and other football pads understood by those of ordinary skill in the art and known in the football industry. The features of U.S. Pat. No. 8,549,674 and other patents cited above are incorporated by reference into the present application.

The devices exemplified by the above-mentioned references primarily attempt to reduce the flexion, extension, lateral bending, and rotation of the head. However, none of the devices disclosed in the above-mentioned references decrease axial compression of the neck without limiting the normal movement of the head of the user, nor do these references provide the degree of support provided by the embodiments of the present invention.

For example, Sims' device is elevated in the rear to contact the back portion of the helmet during the extension of the neck of the user, effectively restricting the backward movement of the head of the user. Sims' device is also tapered in the front and connected with a lace. Mitchell's device is to be worn on the top of shoulder pads. Mitchell's device is thick and four-sided with rounded edges. As appreciated by those skilled in the art, Mitchell's device prevents the normal movement of a player's neck and head. Aaron's device is attached to the helmet and shoulder pads by fasteners that inevitably restrict the normal movement of a player's head and neck. LaPorta's device has back and chest plates that are attached using a curved pad providing little or no support in minimizing damage to the spine. Howard discloses a neck cushion that is an integral part of the helmet. The back of the cushion is raised, inevitably restricting the movement of the user's head and neck.

Fair '339 and Fair '720 disclose a protective vest having a collar guard designed to engage with a player's neck or helmet with no spine protection. Hartunian discloses a foam neck brace surrounding a user's neck with 360 degrees of cushioning. The conical shape of the neck brace and the way it surrounds the neck of the user inevitably prevents the normal motion of the user. Monica discloses a helmet motion restrictor designed to engage with a football helmet of a user in order to prevent excessive lateral and posterior movements of the football helmet again restricting movement. Abeyta discloses a cervical spine protection device designed to minimize the axial compression of the head of the user, which unduly restricts the posterior and anterior movements of the neck of the user.

Further, when the shoulder pads do not provide any protection to dampen axial force that is enacted on the head and neck of the user. The force is thus fully absorbed by the neck and spine, potentially causing spinal injury.

It is therefore an object of the shoulder pads incorporating a cervical spine protection device of the embodiments of the present invention to reduce axial loading of the spine without limiting movement in flexion, extension, left or right lateral flexion or rotation of the skull.

It is a further object of the shoulder pads incorporating a cervical spine protection device of the embodiments of the present invention to engage the lower most part of a helmet during axial compression so as to relieve the pressure on the spine.

It is a further object of the shoulder pads incorporating a cervical spine protection device of the embodiments of the present invention to include at least one damper element to at least partially attenuate the axial force enacted on the spine.

It is a further object of the shoulder pads incorporating a cervical spine protection device of the embodiments of the present invention to be worn with various types of regulation helmets and regulation shoulder pads, so as not to interfere with movement of the head of a user, or the normal workings of the helmet and/or the shoulder pads.

It is a further object of the shoulder pads incorporating a cervical spine protection device of the embodiments of the present invention to provide a protection device that is simple to use, lightweight, and economical to construct.

SUMMARY OF THE INVENTION

The embodiments of the present invention are directed to a shoulder pad having a cervical spine protection system including: shoulder pads; and a cervical spine protection device including: an upper portion designed for engagement with a user's helmet when an axial force is applied to a portion of the helmet, the upper portion having a front section, a rear section, and side sections, wherein the front section, rear section, and side sections of the upper portion have a top surface; and at least one damper element within the cervical spine protection device; wherein the axial force applied to the top portion of the helmet is at least partially absorbed by the cervical spine protection device and at least partially directed away from a cervical spinal column of the user by the cervical spine protection device, wherein the at least one damper element, when the axial force is at least partially absorbed by the cervical spine protection device, resistively collapses so as to at least partially attenuate the axial force, wherein the cervical spine protection device allows extension of the head and neck during athletic movement.

DETAILED DESCRIPTION

The embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the illustrated embodiments set forth herein. Rather, these illustrated embodiments are provided so that this disclosure will be thorough and complete and will convey the scope of the invention to those skilled in the art.

In the following description, like reference characters designate like or corresponding parts throughout the figures. Additionally, in the following description, it is understood that terms such as “top,” “bottom,” “side,” “upper,” “lower,” “front,” “back,” and the like, are words of convenience and are not to be construed as limiting terms.

The embodiments of the present invention are directed to a shoulder pad incorporating a cervical spine protection device that minimizes damage to the spinal column and spinal cord while allowing substantially unrestricted movement of the head and neck during athletic activity.

The cervical spine protective device of the embodiments of the present invention is designed to reduce the possibility of neck injuries in contact sports, without restricting the normal neck movement of a player during collision. In a preferred embodiment, the device of the present invention contacts the lower most parts of the sides of a player's helmet, and has a shape that is molded to the normal anatomy of the upper back and lower cervical spine. Force received at the top of the helmet is applied to the protective device, absorbed by the protective device, and directed away from the cervical spinal column while allowing extension of the head and neck. It is a feature of the embodiments of the present invention that the device directs axial force away from the spine area. It is another feature of the embodiments of the present invention that the device includes damper elements that resistively collapse so as to at least partially attenuate the axial force. Though the embodiments of the present invention reduce axial load in an attempt to reduce forces from the head toward the neck, one skilled in the art will understand that there is no way to protect the neck and spine in all incidences of collision from injury.

Neck injuries in contact sports can vary from the rare catastrophic event, to the much more frequent but less severe neck stinger. Specifically, brachial plexopathy, known as a stinger or burner, is a common injury in contact sports, particularly in competitive football. Studies have shown lifetime injury incidences from 49% to 65% in college football. As a result, many players wear neck collars to prevent such injuries. A stinger is most likely caused by damaging the upper trunk of the brachial plexus, which is made up of the C5 and C6 nerve roots. This group of nerves runs from the cervical spine through the shoulder and into the upper arm, traveling directly under the clavicle. Stingers usually involve excessive hyperextension or lateral flexion of the head due to an impact, either with another player or with the ground. Symptoms include numbness, pain, or a stinging or burning sensation in the shoulder and/or arm. Usually, these symptoms resolve within minutes. However, this simple neuropraxia can escalate into an axonotmesis (damage to the axon or myelin sheath) that lasts for days or months, or a neurotmesis (complete disruption of the nerve), which is permanent.

Severe injuries often result from axial loading injuries. When the neck is flexed 30 degrees from anatomic position, the normal cervical lordosis is straightened and the vertebrae align into a segmented column. An impact to the head will result in a crushing of the vertebrae, with the surrounding soft tissues unable to absorb the impact (Torg, 1990). Such impacts usually result in paralysis or death.

Referring now to the Figures, FIG. 1 illustrates a front view of a cervical spine protection device 10 according to an embodiment of the present invention as worn by a user (shown as a football player in the figures). FIGS. 3 and 4 illustrate respectively a rear and side view of the device of FIG. 1. The device 10 can be constructed of various materials including plastic, polyurethane, foam, or the like (or a combination of the aforementioned materials or the like). It is to be understood that the device 10 can come in different sizes depending on the neck size of the player or other relevant factors (for example, including but not limited to, the sport being played by the intended user). The embodiments of the present invention may include materials having different densities. For example, a device according to an embodiment of the present invention may be denser than another embodiment of the present invention. The embodiments of the present invention may include varying densities throughout the device. For example, an embodiment of the present invention may include an upper portion 15 that is less dense than a lower portion 20. Additionally, an embodiment of the present invention may include an upper portion 15 that is less dense than a middle portion 30, which is in turn less dense than a lower portion 20. Moreover, a middle portion 30 may be more or less dense than the upper portion 15 and/or lower portion 20. Further, for example, an embodiment of the present invention may include an upper portion 15 that is denser than a lower portion 20. The densities of the device 10 may vary for reasons including, but not limited to, application (e.g., sport, position), user preference, injury history, or the like. One skilled in the art will recognize that the densities and varying densities of the device 10 are not limited to the specific embodiments described herein.

The protection device 10 of the embodiments of the present invention is designed to be worn in conjunction with a helmet, which may be a football helmet 11, and shoulder pads, which may be football shoulder pads 23. The shape of the protection device 10 of the embodiments of the present invention is provided to accommodate the normal anatomy of the upper back and lower cervical spine of a human being. The device 10 includes an inside portion 22 and an outside portion 24, where the inside portion 22 is designed and shaped/contoured to fit around the neck of a user (see FIGS. 1, 3 and 4), and the outside portion 24 is shaped/contoured to engage with shoulder pads 23 (see FIGS. 7 and 8).

At a back portion 26 of the device 10 according to an embodiment of the present invention, there is a back opening 12 and similarly there is a front opening 14 at a front portion 28 of the device 10. The purpose of these openings is to allow unrestricted movement of the head and neck during athletic movement. The device 10 also includes a middle portion 30 located in a generally centralized elevational position of the device 10, upper portions 15 that extend toward the lower edge 34 of the helmet 11, and lower portions 20 that are shaped/contoured to rest on the shoulders of the user and fit adjacent to/under shoulder pads 23. Further, the device 10 includes side portions 32 in-between the back and front portions 26, 28. The back opening 12 is preferably shaped such that a maximum width of the opening 12 is substantially equal to the width of a user's neck. One skilled in the art will recognize that the width of a user's neck varies depending upon the sex of the user, age of the user, athletic ability of the user, fat content of the user, muscle content of the user, and the like. One skilled in the art will recognize that the embodiments of the present invention may be sized to fit any variations of the above depending upon the application.

The focus of the embodiments of the present invention is to absorb the force of an impact at the top 36 of the head and/or helmet 11. Most catastrophic injuries in contact sports occur when the head is driven down toward the neck and shoulders producing pressure too great for the cervical spine to handle. This extreme pressure can cause a buckling of the spinal column and can lead to disc herniation, muscle and ligament damage, and severe spinal cord injury. The protective device 10 of the embodiments of the present invention provides the necessary support in order to minimize spinal cord injury that could result from excessive force being applied to the top 36 of a player's head and/or helmet 11, while at the same time allowing freedom of movement for the head and neck.

An embodiment of the present invention includes compression elements 13. More particularly, FIG. 6 illustrates a compression element 13, which can be inserted within an embodiment of the device 10 as shown in FIG. 5. FIG. 5 is a cross-section looking toward the back portion 26 of an embodiment of the device 10 illustrating how the compression element 13 is inserted within the device 10. FIG. 4 is a side view of an embodiment of the device 10 illustrating how a plurality of compression elements 13 may extend around the periphery of device 10 according to an embodiment of the present invention. FIG. 4 shows three individual compression elements 13 on the side portions 32 of device 10, but it is to be understood that a greater or lesser number can be used depending on the degree of support required. For example, and as explained herein, an embodiment of the present invention does not include any compression elements 13—that is, the device 10 itself and its unique shape act as the compression element.

In an embodiment of the present invention that includes compression elements 13, the compression element 13 can be made from a stiff polyurethane material (or any similar material) that can provide adequate support. The upper surface 16 of the compression elements 13 is designed to support the upper surface 40 of the upper portions 15 to provide a generally wide contact area that may receive the lower edges 34 of the helmet 11 when excessive force is applied to the top 36 of the helmet 11. The width of this contact area on the upper portions 15 can vary depending on the type of helmet worn by the player. For example, the width may be in the approximate range of 2 to 4 inches wide at the widest point. However, the width may be wider (e.g., 4 inches or larger), and is not limited to the sizes disclosed herein.

The lower surface 17 of the compression elements 13 is designed to follow the contours of the player's neck and is specifically shaped to direct force away from the cervical spinal column. This is illustrated by arrow 18 representing a downward force applied to the upper surface 16 when an excessive force is received at the top 36 of the head and/or helmet 11, forcing the lower edges 34 of the helmet 11 onto upper portions 15 of the device 10. This force is then directed from a downward direction as shown by arrow 18 to an oblique direction as shown by arrow 19. Apertures 21 shown in FIG. 6 are illustrative only and can be used, if necessary, to reduce the weight of compression element 13 or for other reasons known to those of ordinary skill in the art, such as securing the device 10 to shoulder pads 23.

As stated above, an embodiment of the present invention does not include compression elements as shown in FIG. 6, but rather the function of the compression element is performed by the material and shape of the device itself. For example, an embodiment of the present invention may include a device 10 that is molded as one-piece out of a synthetic material or the like (for example, foam or the like). This material is preferably selected such that the device 10 can provide adequate support without a separate compression element present. In the embodiments of the present invention that do not include separate compression elements, the upper portions 15 are shaped with an upper surface 40 to provide a generally wide contact area that may receive the lower edges 34 of the helmet 11 when excessive force is applied to the top 36 of the helmet 11. Again, the width of this contact area on the upper portions 15 can vary depending on the type of helmet worn by the player. For example, the width preferably is in the approximate range of 2 to 4 inches wide at the widest point.

The middle portion 30 and the lower portion 20 of the device 10 are designed to follow the contours of the player's neck and are specifically shaped to direct force away from the cervical spinal column. This is illustrated by arrow 18 representing a downward force applied to the upper surface 16 when an excessive force is received at the top 36 of the head and/or helmet 11, forcing the lower edges 34 of the helmet 11 onto upper portions 15 of the device 10. This force is then directed from a downward direction as shown by arrow 18 to an oblique direction as shown by arrow 19.

As set forth above, the embodiments of the present invention are designed to protect against spinal cord injury when excessive force is applied to the top 36 of a player's helmet 11, which can result in axial compression of the spine. Injury is minimized by filling the gap between the lower edge 34 (bottom sides and back bottom) of a player's helmet 11 and the lower neck and upper shoulder of the player with the device 10. In an embodiment of the present invention, force directed at the top 36 of the helmet 11 is applied to the device 10 at the upper portion 15 and absorbed by the compression elements 13, which direct the force away from the cervical spine. In another embodiment of the present invention, force directed at the top 36 of the helmet 11 is applied to the device 10 at the upper portion 15 and absorbed by the device 10 itself (through its unique shape and its material), where the device 10 directs the force away from the cervical spine. The disclosed embodiments of the present invention also allow unrestricted movement of the head and neck during athletic activity.

The shape of the device 10 of the embodiments of the present invention, as shown in the figures, will now be described in more detail. As shown in FIG. 3, the back portion 26 of the device 10 preferably includes a substantially v-shaped design 38. In an embodiment of the present invention, the back portion of the device 26 also includes an opening 12 that is sized and shaped to allow a person wearing a device 10 and a helmet 11 to move their head and neck backwards (toward their back and away from their chest) without substantial restriction. The opening 12 creates a valley 42 in the back portion 26, which is at a lower point elevationally than the top surface 40 of the upper portion 15 of the device 10 (as shown in FIG. 5). In other words, when wearing the device 10 and a helmet 11, the upper portions 15 would be closer to the lower edge 34 of the helmet 11 than the valley 42 of the back portion 26 (as is evident from FIGS. 1 and 3). Therefore, if a user (for example, a football player) was wearing the device 10 and a force was applied to the top 36 of the user's head and/or helmet 11, the valley 42 is at an elevation such that the lower edge 36 of the helmet 11 would contact the top surface 40 of the upper portion 15, and not the valley 42 of the back portion 26. Therefore, the opening 12 at the back portion 26 of the device 10 (as used throughout this description) is not necessarily an “opening,” but rather, the opening 12 may simply be describing the back portion 26 of the device 10 having a lower surface elevationally than the top surface 40 of the upper portion 15. One skilled in the art will understand that the opening 12 assists in allowing extension of the head and neck during athletic movement when a user is wearing the device 10.

As discussed herein, the device 10 is shaped to direct a force occurring at the upper portions 15 (this force is shown by arrow 18, i.e., a force in a downward direction on the top surface 40 of the upper portion 15) away from the cervical spine (the redirected force is shown by arrow 19, i.e., an oblique direction). As depicted in FIGS. 1-3 and 5, the outside portion 24 of the device 10 includes a substantially c-shaped design, with the lower portions 20 and the upper portions 15 extending laterally further than the middle portion 30 of the device 10. In an embodiment of the present invention, the lower portions 20 are shaped to fit comfortably on the shoulders of a user beneath the shoulder pads that are typically worn by athletes (for example, football players), as is apparent from the shape of the device 10. The upper portions 15 include a top surface 40 that extends from the inside portion 22 of the device 10 to the edge of the side portions 32 of the device 10 beyond the middle portion 30 of the device 10. In an embodiment of the present invention, the upper portions 15 do not extend as far as the lower portions 20, and the upper portions 15 are shaped to fit above the shoulder pads that are typically worn by football players (as is apparent from the shape of the device 10). In an embodiment of the present invention, the shape of the device 10 assists in directing a force occurring at the upper portions 15 (arrow 18, i.e., a downward direction) away from the cervical spine (arrow 19, i.e., an oblique direction).

While there has been described what is considered to be a preferred embodiment of the invention, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the invention, and therefore, it is the aim of the appended claims to cover all such changes and modifications as fall within the true spirit and scope of the invention.

The device 10 according to the embodiments of the present invention was created with the simple knowledge in mind that the head is connected to the neck. The forces generated during impact from the head to the neck need to be absorbed, or lessened, in some way. For example, in the context of football, as helmets collide, the force that is generated from that collision goes directly from the helmets to the head and into the spine. Without the presence of the device 10 according to the embodiments of the present invention, there is nothing to absorb those forces. The embodiments of the present invention are preferably constructed in order to achieve a balance between flexibility and stability where it is needed.

An embodiment of the present invention includes a device 10 (collar) with a streamlined base 44. A device 10 according to an embodiment of the present invention also includes flexibility. In an embodiment of the present invention, the streamlined base 44 and the flexibility of the device 10 are present such that the device 10 can fit into shoulder pads, for example, football shoulder pads 23. Specifically, in this embodiment, the streamlined base 44 is present to hold the device 10 in place into the shoulder pads 23, and is designed for comfort and movement when a sports player is playing their respective sport (for example, the flexibility provides increased movement and comfort for a user). In an embodiment of the present invention, the streamlined base 44 and the flexibility of the device 10 are not part of the compressive element of the device 10. In another embodiment of the present invention, the streamlined base 44 and the flexibility of the device 10 are part of the compressive element of the device 10.

The devices 10 according to the embodiments of the present invention are designed such that they do not restrict the range of motion at all during play. In other words, a user of the device 10 of the embodiments of the present invention will be able to move their head from side to side, front to back, and will be able to turn their head as they normally would without the device 10 present during play. However, when a user of the embodiments of the present invention makes contact with their head in a way that would compress the spine without the device 10 present (for example, a football player hitting another player with the top 36 of their helmet 11), as a user makes contact, the helmet 11 of a user is forced to make contact with the upper portion 15 of the device 10. The upper portion 15 of the device 10 absorbs some of the forces that are generated during impact and deflects/distributes some of the forces that are generated during impact away from the head and neck area.

In an embodiment of the present invention, when a user is wearing the device 10, and is in a “football position,” a user is able to move around. It is only at the point of impact, i.e., when a user braces for a hit or makes contact, that the device 10 according to the embodiments of the present invention engages the bottom of the helmet 11.

Another embodiment of the present invention includes an opening 12 in the back portion 26 of the device 10, and therefore, there is nothing that restricts the movement of a user's head from moving backwards when wearing the device 10. When a player experiences impact, it is important that the player's head is not restricted from moving backward so that the head can travel away from an opposing force. The embodiments of the present invention are designed to limit axial loading on the head and neck during impact. As a force comes down on a user's head, the embodiments of the present invention reduce some of the axial load force while allowing the user's head to travel backwards, which allows a disbursement of some of the forces generated during impact.

As stated above, the device 10 according to the embodiments of the present invention preferably works in conjunction with shoulder pads 23. Specifically, a device 10 according to an embodiment of the present invention preferably fits into shoulder pads 23. An embodiment of the present invention is contoured to fit directly into a pair of shoulder pads 23. The device 10 is preferably further secured into the shoulder pads 23 to make sure the device 10 stays in place during use. The securing of the device 10 is preferably accomplished through a securing means or fastening means which may include snaps, a lace/string/tie, Velcro (i.e., hook and loop), tape (or other adhesive), clamps, clips, couplings, docks, hooks, latches, pins, buttons, slides, tongue and groove attachments, or the like.

In an embodiment of the present invention that includes laces, the device 10 is contoured to fit directly into a pair of shoulder pads 23 and then is laced to the shoulder pads 23 to make sure the device 10 stays in place. In other words, attachment of the device 10 for use includes tying the device 10 into a pair of shoulder pads 23 using a “tie-in” system comprising, for example, three to six laces to fasten the device 10 to the shoulder pads 23. By way of an example, the following describes how an embodiment of the present invention that includes laces 46 can be fit into a pair of shoulder pads 23. The opening 14 of the device 10 is preferably aligned with the opening (front) 25 of the shoulder pads 23. The device 10 may then be laced into the shoulder pads 23 through tying the device 10 into position using the laces 46. In an embodiment of the present invention, the front of the device 10 includes laces 46 for tying around/through shoulder pads 23. Additionally, an embodiment of the present invention may include laces 46 at the back of the device 10 for tying around/through shoulder pads 23 (or at both the front and back of the device 10). An embodiment of the present invention may include additional laces as well for extra stability. An embodiment of the present invention may also include holes 48 in which the laces 46 may be threaded through.

When the device 10 according to an embodiment of the present invention is correctly engaged with the shoulder pads 23, the device 10 is preferably open in the front 28, the sides 32 are preferably adjacent to the inside side portions 27 of the shoulder pads 23, and the back portion 26 of the device 10 is preferably below or even with the top back portion 29 of the shoulder pads 23. The inside 22 side portions 32 of the device 10 preferably touch a user's neck when a user is wearing the shoulder pads 23 with the device 10 engaged therewith. The device 10 preferably does not indent the user's neck, but rather the device 10 should barely touch the skin. The device 10 is contoured to fit streamlined into the shoulder pads 23 in order not to change the shape of the shoulder pads 23 and to work better with the shoulder pads 23.

Another embodiment of the present invention includes a cervical spine protection device as described herein that is integral with a pair of shoulder pads. In other words, the protection device is a part of the shoulder pads themselves, and not a separate element.

Only at the point of impact does the device 10 engage the bottom 34 of the helmet 11 in order to absorb and distribute the force of an impact (hit) away from the neck and spine of a user. During normal play and physical activity, however, the device 10 preferably does not restrict movement of the user at all.

The device 10 according to the embodiments of the present invention is designed to absorb some of the impact to the head, neck, and spine during collision. There is no device, however, that can absorb all of the forces during impact, and a user should not think that once they have the device 10 in place during sport, they are immune to injury to the head or neck. In other words, a person wearing the device 10 may still sustain an injury to the head, neck, and spine during collision.

The design 10 of the embodiments of the present invention preferably includes flexibility such that the device 10 is flexible in nature, and is able to move back and forth and side to side. The device 10 can be comfortably worn by a user during play because of its flexibility and shape.

As stated above, an embodiment of the present invention does not include compression elements, but rather the function of the compression element is performed by the material and shape of the device 10 itself. The material is preferably selected such that the device 10 can provide adequate support without a separate compression element present. A preferred embodiment of the present invention is constructed of a material similar to “smartLite®” or the like (foam made of a thermoplastic, polyester, or polyether). The material in a preferred embodiment of the present invention includes a microcellular structure, which can include open cells and/or closed cells (microscopic). The closed cells do not allow for the penetration of, for example, water or other liquids. For example, the outside surfaces of the device 10 in a preferred embodiment of the present invention include manufacturing such that perspiration, water, dirt, and the like cannot be absorbed into the material of the device 10. As stated herein, the density of the material may vary, and the density is not restricted to certain values for the embodiments of the present invention. An example of the density of the material of the device 10 is 0.50 g/cc to 1.00 g/cc, but a person of ordinary skill in the art will recognize that the density may be greater than this value, or lower than this value. The material may be injection molded to form the embodiments of the present invention. The injection molding process allows the material to closely mimic the surface texture of the mold, which can allow for different surface finishes in the embodiments of the present invention. The material in a preferred embodiment of the present invention allows for the device to have a hardness in the range of 35-55 ShA, but a person skilled in the art will understand that embodiments of the present invention include devices with higher or lower Shore A values.

In addition to the embodiments of the present invention optionally including different and/or varying densities, embodiments of the present invention include devices 10 that have different and/or varying flexibility and/or elasticity. For example, a preferred embodiment of the present invention includes a device 10 with an upper portion 15 that includes more material than the lower portion 30. This design allows for more elasticity and flexibility of the lower portion 20 compared to the upper portion 15. Another embodiment of the present invention includes a device 10 with an upper portion 15 that includes more material than the middle portion 30, which in turn includes more material than the lower portion 20.

In a contact sport with shoulder pads 23, before and during impact, the shoulders typically rise up, and thus the shoulder pads 23 rise up, and the base 34 of the helmet 11 of a player hits the device 10 according to the embodiments of the present invention when a user is wearing the device 10.

The embodiments of the present invention may be used to prevent the injury commonly referred to as a “stinger.” This is because the embodiments of the present invention distribute the force of impact away from the neck and spine.

The embodiments of the present invention are directed to a device 10 that may be used by a player engaged in sport. For example, the embodiments of the present invention may be used when playing the following sports: football (for example, American football), lacrosse, hockey, water polo, wrestling, sumo, martial arts, boxing, or the like. One skilled in the art will understand that the device 10 according to embodiments of the present invention may be used in any activity or walk of life in order to aid in the prevention of spine/neck injury. As used throughout this application, “player” or “user” may be any person attempting to prevent or limit the risk of spine/neck injury. While “football” is discussed for use of the device 10 throughout this application, one of ordinary skill will recognize that the embodiments of the present invention are not limited for use by football players. Therefore, the shoulder pads and helmet discussed throughout this application may be in the form of shoulder pads/helmets used in sports other than football (e.g., lacrosse, hockey, or the like).

An embodiment of the present invention provides critical protection without hindering player performance.

In an embodiment of the present invention, the low profile design creates a natural fit into shoulder pads 23.

The device 10 according to the embodiments of the present invention can lower head accelerations resulting from a top impact. The device 10 according to the embodiments of the present invention can also reduce force transmission through the neck. In a top impact, the device 10 redirects some of the load to the shoulders, on which the device 10 rests. The stiffness of the device 10 prevents the neck from further compression. The device 10 also provides protection during an impact to the front of the head and/or helmet 11. The device 10 can reduce upper neck moment and lower neck force in all configurations. The device 10 also can reduce the lower neck moment in a raised configuration. The device 10 according to an embodiment of the present invention restricts the range of motion of the head and neck by contacting the base 34 of the helmet 11 during an impact (this is observable during high-speed video). This contact between the helmet 11 and device 10 is responsible for lower loads.

The device 10 according to the embodiments of the present invention will typically perform better in the raised position (when a user's shoulders are raised upward) because the helmet 11 will contact the device 10 sooner and restrict more motion. In a side impact, the device 10 according to the embodiments of the present invention may reduce a lower neck moment. Again, this is due to the base 34 of the helmet 11 contacting the device 10, restricting the range of motion. This movement restriction is most noticeable in a high speed video The device according to the embodiments of the present invention is designed to contact the base 34 of the helmet 11, which restricts motion of the head and neck during impact. Restriction of motion during impact correlates with load reductions.

With a front impact location, the device 10 can reduce lower neck movement, and the device 10 is also capable of reducing lower neck force and upper neck movement. With a side impact location, the device 10 can produce lower neck movement reductions.

An embodiment of the present invention includes a molded synthetic collar (the device 10) that rests on the shoulders and gets engaged with (for example, laced into) shoulder pads 23.

In an embodiment of the present invention that includes a compressive element, the density of the compressive element can range from 0.35 to 0.65 grams per cubic centimeter squared. Similarly, in a preferred embodiment of the present invention that does not include a compressive element, the density of the device can range from 0.35 to 0.65 grams per cubic centimeter squared. One skilled in the art will readily understand that the embodiments of the present invention are not limited to the densities disclosed herein.

In an embodiment of the present invention that includes a compressive element, the compressive element may use a methyline Di isolate (MDI) skin polyurethane. Similarly, in a preferred embodiment of the present invention that does not include a compressive element, the device may use a methyline Di isolate (MDI) skin polyurethane.

As will be understood by one of ordinary skill in the art, the device 10 of the embodiments of the present invention can be worn with any shoulder pads used in contact sports, and are not limited to football shoulder pads.

In an embodiment of the present invention that includes a compressive element, the compressive element may include data recording devices imbedded inside such as compression measuring sensors, accelerometers, or similar (and/or any combination of data recording devices). Similarly, in a preferred embodiment of the present invention that does not include a compressive element, the device may include data recording devices imbedded inside such as compression measuring sensors, accelerometers, or similar (and/or any combination of data recording devices).

The embodiments of the present invention further include the methods of making the devices 10 as described herein. For example, a device 10 according to an embodiment of the present invention is made through an injection molding process in which there is a cavity that is shaped to form the device 10 as described herein. In this injection molding process, the material of the device 10 is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the cavity. In a preferred embodiment of the present invention that does not include a compressive element, the device may be made through a single injection molding process. Also, one of ordinary skill will recognize that different materials may be used during the injection molding process, particularly for embodiments of the present invention that include varying densities throughout the device. In an embodiment of the present invention that includes a compressive element, the compressive element may be injection molded in one step, with material added around the compressive element through a second step in the injection molding process. In contrast, the compressive element may be constructed using any process known by those of ordinary skill in the art for forming, for example, plastic parts.

The injection molding process of the embodiments of the present invention may further or alternatively include a non-aggressive screw, a barrel and nozzle temperature of up to 180.degree. C., temperature controls, a non-return valve (which may be on hydraulics to retain pressure on the screw after charging to avoid expansion in the barrel and gas loss), a shut-off nozzle (not restricting the flow; to prevent gas escape through the nozzle and melt drool; hydraulically or pneumatically operated nozzles are preferred over the mechanically activated spring types), and a mold temperature control between 15 and 50.degree. C.

Additional methods of manufacturing the device 10 according to embodiments of the present invention include extrusion, flow molding, thermoforming, physical shaping, or the like.

The embodiments of the present invention further include the methods of using the devices 10 as described herein. For example, a user preferably fastens/secures the device 10 according to the embodiments of the present invention to shoulder pads 23 using one of the fastening means described herein, for example, laces 46. Alternatively, a user may simply put on the embodiment of the present invention in which the device 10 is integral with the shoulder pads 23. A user then preferably wears a helmet 11 before engaging in physical activity.

FIGS. 18 and 19 are front views of a cervical spine protection device according to an embodiment of the present invention as worn in conjunction with shoulder pads known in the art. When used with shoulder pads as shown in FIGS. 7, 8, 18, and 19, the upper surface 40 of the device 10 is preferably higher than the upper surface 50 of the shoulder pads 23. In addition, as shown in FIG. 1, and FIGS. 22A-C, the lower “ear” portion 60 of a typical football helmet 11 makes contact with the upper surface 40 of the device 10, thereby making the device 10, when incorporated into shoulder pads 23, part of an energy transfer system that transfers the axial force applied to a football helmet 11 during a tackle to the device 10 instead of to a person's cervical spine. The dotted lines shown in FIG. 18 show the lower portion 20 of the rear portion device 10 when incorporated into the shoulder pad 23, and how the lower portion 20 of the rear portion of the device 10 is situated when the device 10 is incorporated in the shoulder pad 23.

As shown in FIGS. 18 and 19, known football shoulder pads are generally bilaterally symmetrical and are generally comprised of right and left body arch members 50, 51 which extend over the shoulders and include anterior and posterior portions, and chest and back portions 52, 53, which overlie the chest and back of an athlete. The posterior portions back portions may be permanently hinged together along a vertical axis over the athlete's back or spine, while the anterior portion, or chest portions, are typically connected together on a vertical line over the athlete's sternum as by means of straps or lacing.

A side pad assembly 54, 55 typically comprise an epaulet and a shoulder cap, is typically rigidly linked by multiple connectors to the body arch member. The side pad assembly protects the player's shoulder where a portion of the body arch member typically overlies the clavicle and the lateral extension of the spine of the scapula. In general, the area of the shoulder extends from the base of the neck downwardly towards the tip of the shoulder, or deltoid muscle. With conventional shoulder pad designs, the epaulet is typically pivotally connected to the arch member by a first strap and the shoulder cap is typically pivotally connected to the arch member by a second strap, wherein the epaulet typically overlies the shoulder cap. Due to the rigid connection provided by the straps, the range of motion of the side pad assembly is typically limited and the overall comfort of the shoulder pad is affected. The structural members, such as the body arch members, the shoulder caps and the epaulets, are typically manufactured from a material having the requisite strength characteristics to withstand the forces of impact incurred while playing football. Conventional shoulder pads may also include a strap of material which has its ends fixedly secured to the body arch member, as by rivets or other suitable connectors. Typically, these straps are referred to as cantilever straps, and they support the body arch members in a spaced relationship from the pad body, as well as from the shoulder of the player.

Unlike football shoulder pads which include two distinct pads, the epaulet and the cap, which overlie the player's shoulder for protection thereof, conventional hockey and lacrosse pads typically feature only the shoulder cap. Existing shoulder pads also utilize a number of distinct interior pads disposed beneath the body arch members, wherein the interior pads are either fixedly secured, or releasably secured, to the body arch members. By using a number of distinct interior pads to form the interior pad elements, the construction of the shoulder pad and the fit of the shoulder pad can be affected.

The present invention as shown in FIGS. 18 and 19, as used with shoulder pads, take into account the cervical spine, and is capable of providing protection not only to the cervical spine and shoulder but also to the neck area. The aspects of the present invention will change the shoulder pad concept into an energy transfer system. Based on this energy transfer system, the device 10 decreases axial loading first, resulting in a reduction in the hyperextension of the head.

FIG. 20 is a rear view of another embodiment of a cervical spine protection device according to an embodiment of the present invention, similar to the view shown in FIG. 13 above. FIG. 20 illustrates that a preferred embodiment of the device 10 is separable from the shoulder pads 23. In another embodiment, the device 10 can be a permanent part of the shoulder pads 23, attached using methods of manufacturing known in the art.

FIG. 21 is a rear view of a cervical spine protection device according to an embodiment of the present invention as worn in conjunction with shoulder pads. The shoulder pads preferably have different levels of height. The highest point of the shoulder pads will preferably be in the neck area. The body portion of the shoulder pads 23 will preferably be lower than the neck area and the deltoid portion of the shoulder pads 23 will preferably be higher than the body portion. The neck portion of the shoulder pads can be increased in a vertical direction based on a football player's neck. The shoulder pads shown in FIGS. 18, 19, and 21 are preferably made from a material that absorbs shock. The material will be softer nearest to the body and preferably include a hard outer “shell.” Although the outer shell of the shoulder pad is harder it will preferably still have shock absorbing capability.

The shoulder pads preferably include a ventilation system consisting of holes to allow flow of air. This system of holes will be throughout the entire shoulder pad except the neck area. The holes will preferably be ¼ inch in diameter, and separated by 1/16″ spacing between each hole, and as mentioned above, preferably covering at least body arch members 50, 51 of the shoulder pad; side pad members 52, 53 may also include such ventilation systems. As used in this specification, the words “shoulder pad” and “shoulder pads” are used interchangeably and generally denote one set of shoulder pads used for one football player.

The cervical spine protection device 10 can also include at least one damper element 100, as shown in FIGS. 23A-25. The damper element 100 assists in decreasing and absorbing the force enacted on the spinal column. When the axial force from the helmet 11 is at least partially absorbed by the cervical spine protection device 10, the damper element 100 resistively collapses so as to at least partially attenuate the axial force. The damper element 100 helps absorb and reduce the acceleration and force from the impact on the helmet 11. As such, the cervical spine protection device 10, along with the at least one damper element 100, at least partially absorbs and reduces the axial force from an impact on the helmet 11, and also at least partially directs the axial force away from the cervical spinal column of the user.

When the helmet 11 engages the device 10, the helmet 11 engages the apex. The device 10 absorbs the impact and the force from the impact and, as described above, begins to bend along the middle portion 30. The force absorption unit 100 at least partially attenuates the axial force by resistively collapsing. As such, the acceleration of the impact is decreased, thus decreasing the force absorbed by the device 10 and subsequently the spinal column.

As shown in FIG. 23A, the damper element 100 can include a spring 101. The spring 101 can be a coiled spring that compresses slowly upon impact to dampen the forces created during engagement of the helmet and the device 10. The spring 101 can be made from metal, plastic rubber, form, or any suitable material that resistively collapses when under a force and rebounds back to an original state when the force is removed.

The damper element 100 can also include a fluid inside an inner chamber. The fluid further resists, disperses, or manages the force enacted on the damper element 100. The damper element 100 can structurally resist the force initially, and then compress, collapse, or buckle to vent the fluid through at least one orifice to at least partially attenuate the force. As shown in FIG. 23B, the damper element 100 can include a hydraulic pump 102. As shown in FIG. 23C, the damper element 100 can include an air bladder 103.

The hydraulic pump 102, as shown in FIG. 23B, can be encased inside the device 10. The hydraulic pump 102 can be made of hard plastic parts, a flexible metal, or a combination thereof. As the force from the helmet 11 is applied to the upper surface 40 of the device 10, the fluid slowly dissipates from an inner chamber into another chamber. The another chamber can be within the hydraulic pump 102, or the another chamber can be a separate holding tank. The fluid can pass through at least one orifice which provides a resistance in the flow of the fluid. In at least one embodiment of the present invention, the walls of the hydraulic pump 102 can be formed so as to contribute to force absorption. For example, the walls of inner chamber of the hydraulic pump 102 can initially resist the force, and then buckle to allow the force to be resistively absorbed by the venting of the fluid through the orifice. After the force is removed, the inner chamber of the hydraulic pump 102 takes in fluid to a loaded compression level by creating a negative pressure inside the inner chamber as the hydraulic pump 102 expands and regains its form from being collapsed. The fluid in the hydraulic pump 102 can be hydraulic fluid, oil, water, or any suitable fluid that has the ability to respond under force.

The air bladder 103, as shown in FIG. 23C, resistively collapses and vents air from within an inner chamber. The air bladder 103 can have a release valve that slowly releases the air as pressure is applied to the air bladder 103. The air bladder 103 can include at least one orifice for resistively venting the fluid from the inner chamber so as to at least partially attenuate the axial force. The negative pressure within the air bladder 103, when the force is removed, causes air to refill the air bladder 103. The air bladder 103 can be made of a polymer material and can be shaped so as to contribute to force absorption. For example, the walls of the air bladder can initially resist the force, and then buckle to allow the force to be resistively absorbed by the venting of the fluid along with the compression of the air bladder 103.

The damper element 100, as shown in FIG. 23D, can also be made of a different material. The interior of the damper element 100 can contain a grid structure 104 such that the grid structure 104 resistively collapses when a force is enacted thereupon, and rebounds to an original state when the force is removed. The grid structure 104, as illustrated in FIG. 23D, is a honeycomb structure, but the grid structure 104 can have any suitable configuration such that the grid collapses upon itself when absorbing a force and rebounds when the force is removed.

The damper element 100 is not limited to the above described embodiments. The damper element 100 can be any suitable form, shape, and material that at least partially attenuates the force absorbed by the device 10 when engaged by the helmet 11. For example, the damper element 100 can be made of a material that has a different density or elasticity than the device 10, such as a gel. In other embodiments of the present invention, the damper element 100 can be a different structure and shape than illustrated. For example, the damper element 100 can include elastic finger-like projections that resistively bend or collapse when encountering a force and reflects back to its original state when the force is removed.

The damper element 100 is not limited to the illustrated embodiments, and can be any structure, shape, or material so long as the force is at least partially attenuated.

The damper elements 100 are placed where the impact and force from the helmet 11 to the device 10 can be absorbed and reduced. For example, the damper element 100 can be located within the device 10, as shown in FIGS. 23A-D. In at least one embodiment of the invention, the damper element 100 is contained within the device 10 in the side sections 32 of the upper portions 15. The damper element 100 can be contained within the device 10 proximate an apex of the device 10 and the shoulder pads 23 which is higher than the top surface of the front section and the rear section when the cervical spine protection device 10 is worn by a user. As such, when the upper portion 15 of the device 10 begins to collapse, the damper element 100 attenuates the force being absorbed by the device 10 and slows down the collapse of the upper portion 15 and the device 10. A lesser force is then being distributed and directed away from the cervical spinal column of the user by the cervical spine protection device 10. Thus, a lesser force is absorbed by the spinal column which is not directed away, if the device 10 does not direct all of the force away from the spinal column.

The damper elements 100 can also be placed at the upper surface 40 of the device 10, as shown in FIG. 24. As such, when the helmet 11 engages the device 10, the helmet 11 first engages the damper element 100 which at least partially attenuates the force enacted on the device 10 and subsequently the spinal column of the user. One exemplary location on the device 10 that the damper element 100 may be placed is on the upper surface 40 of the apex of the device 10. Damper elements 100 may also be placed anywhere the helmet 11 may engage the device 10. In at least one embodiment of the present invention, a rigid layer can be overlaid above the damper element 100 such that even if the helmet 11 does not directly engage the damper element 100, the helmet 11 does engage the rigid layer which then collapses the damper element 100.

Further, the damper elements 100 can be placed on a bottom surface 41 of the upper section 15, as shown in FIG. 25. As such, when the helmet 11 engages the upper surface 40 of the device 10, the upper portion 15 absorbs the force and begins to collapse, and the device 10 bends along the middle portion 32. The damper element 100, being along the bottom surface 41 of the upper section 15, engages the top of the shoulder pads 23. The damper element 100 absorbs and reduces the force from the impact, slowing down the collapse of the device 10. The damper element 100 at least partially attenuates the force being absorbed by the device 10 and, ultimately, the spinal column of the user.

The damper element 100 can also include sensors that will indicate when the damper element 100 have exceeded its limits and requires replacement. The sensors can be visible to the user such that the user can easily determine the status of the damper element 100. For example, the sensors can change colors when the damper element 100 needs replacement.

Any number or combination of damper elements 100 can be utilized. For example, an air bladder 103 can be combined with a spring 104. In yet other embodiments of the present invention, two or more damper elements 100 can be utilized in series to increase the attenuation of the force. For example, two air bladders 103 can be incorporated into the device 10. The first air bladder may vent the air into the second air bladder which may then vent the air out. Further, a damper element 100 can be placed on the upper surface 40 while another damper element 100 can be placed within the upper portion 15.

While the embodiments have been described in detail in the foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only some embodiments have been shown and described and that all changes and modifications that come within the spirit of the embodiments are desired to be protected.
