The present application claims priority under 35 U.S.C. §119(e) of U.S. Provisional Patent Application No. 61/469,570, filed Mar. 30, 2011 titled “Football Shoulder Pads,” the disclosure of which is incorporated herein by reference in its entirety.
FIELDSystems and methods of the present disclosure relate to protective pads. More specifically, the present disclosure relates to protective pads including tethers that are configured to protect a wearer during an impact, such as during contact sports.
BACKGROUNDProtective shoulder pads and other sports related protective pads are worn by players in a number of contact sports, such as football, hockey, soccer, cricket, and lacrosse. Because of the physical nature of such sports, it is important for the protective gear to fit the players with the protective padding aligned with the intended areas on the players' bodies. Misaligned protective gear could jeopardize a player's safety. It is also important for the protective gear to fit comfortably. An uncomfortable fit could hinder a player's physical and mental performance.
Specifically, football shoulder pads are meant to protect athletes from injuries to their upper body. The focus of current shoulder pad design, in football for example, is impact dispersion.
The illustrated traditional shoulder pad assembly 20 may include a rigid upper shoulder pad 26 and a rigid lower shoulder pad 28 operatively connected to one another. For example, the upper shoulder pad 26 may be secured to the vest 22 atop the shoulder while the lower shoulder pad 28 is connected to the vest 22 by a strap. The lower shoulder pads may hang somewhat freely above the wearer's biceps, thus providing some protection and some freedom of movement. Additional examples of known traditional protective pads are shown in: U.S. Pat. No. 4,610,034; U.S. Pat. No. 4,985,931; U.S. Pat. No. 7,168,104; and U.S. Pat. No. 7,647,651.
When a player's arms and shoulders are raised when wearing traditional shoulder pads, the vest rises with the shoulders and the shoulder portions of the vest move inward, pinching the player's neck. This may be uncomfortable for the player, and may restrict the player's movement. Accordingly, a player wearing traditional pads may not be able to reach overhead to an extent that could be achieved if the player were not wearing such pads. Additionally, when a player is impacted in the shoulder, the force imparted to the shoulder pad, although somewhat distributed, is still directed to the underlying shoulder area of the player.
In view of the foregoing, it would be desirable for improved protective pad systems and methods.

The vest 112 may include a chest region 124, a left shoulder region 126, a right shoulder region 128, and a back region 130. A single vest plate 132 (e.g., a monolithic plate) may extend over the chest region 124, shoulder regions 126, 128 and the back region 130. The vest plate 132 may include a split in the chest region 124 to facilitate access for a wearer into the shoulder pad system 110. The straps 134 of the fastening system may facilitate closure of the split in the chest region 124 of the vest 112. Additionally, the fastening system may couple each side of a back region 130 of the vest 112 to a corresponding side of the chest region 124 of the vest 112. For example, adjustable straps 136 may extend across the sides of the wearer, under the arms, to couple the back region 130 of the vest 112 to the chest region 124 of the vest 112.
The shoulder pads 116, 118, 120, 124 may be attached to the respective shoulder regions 126, 128 of the vest 112 with top tethers 138, 140 of the tether system. In one embodiment, as shown in cross section in
The vest 112 may include a first anchor 144 and a second anchor 146 located at each of the left and right shoulder regions 126, 128. As shown in
Each top tether 138, 140 may be comprised of a strap (e.g., a webbing formed from synthetic fibers) having cooperative hook-and-loop fastener features extending along a surface 148 thereof. Accordingly, a free end 150 of the top tether 138 may be pulled after insertion through the first anchor 144 until a desired free length X1 is achieved. The free end 150 of the top tether 138 may then be pressed against a fixed end 152 of the top tether 138 and the cooperative hook-and-loop fastener features on the top tether 138 may interlock.
Similar to the lower shoulder pad 118, a top tether 140 attached near the top of the upper shoulder pad 114 may be routed through the second anchor 146 of the shoulder region 126 of the vest 112. The top tether 140 may be adjusted to position the upper shoulder pad 114 over a gap 154 between the lower shoulder pad 118 and the vest 112. Then, a free end 156 of the top tether 140 may be pressed against a fixed end 158 of the top tether 140 and the cooperative hook-and-loop fastener features on the top tether 140 may interlock.
In an additional embodiment, as shown in cross section in
In addition to top tethers 138, 140, 162, attaching each of the shoulder pads 114, 116, 118, 120 to a respective shoulder region 126, 128 of the vest 112, the tether system may include side tethers 172, 174, 176, 178 attaching shoulder pads 14, 16 to the chest region 124 and the back region 130 of the vest 112.
In the embodiment shown in
The free length X2 (i.e., the length X2 of the side tether 172, 174, 176, 178 between the attachment points at the vest 112 and respective shoulder pad 114, 116, 118, 120) and position of each of the side tethers 172, 174, 176, 178 may be selected to allow the shoulder pads 114, 116 to move upward relative to the vest 112, such as when a wearer's arms are raised overhead. Additionally, the free length X2 and position of the side tethers 172, 174, 176, 178 may be selected to prevent the shoulder pads 114, 116 from moving downward, relative to the vest 112, beyond a specific point (e.g., beyond a point wherein injury may occur to a wearer) when subjected to an impact. Accordingly, impact forces imparted on the shoulder pads 114, 116, 118, 120 may be transferred to the vest 112 through the side tethers 172, 174, 176, 178.
In some embodiments, the side tethers 172, 174, 176, 178 may be relatively rigid, and may stretch relatively little (e.g., less than about 10% of its length) under peak design load. In further embodiments, the side tethers 172, 174, 176, 178 may be somewhat elastic and may stretch (e.g., greater than about 10% of its length) under peak design load. By selecting the fiber material of which the webbing is constructed, the shape and dimensions of the webbing, and the woven construction of the webbing, a webbing material may be selected that provides a desired elastic response for a given application and expected impact forces.
The shoulder pads 114, 116, 118, 120 are rotatable about the top tethers 138, 140. The free length X2 of each of the side tethers 172, 174, 176, 178, and the radial distance of each respective side tether 172, 174, 176, 178 from an axis of rotation (e.g., a distance from the top tether 140) may determine the freedom of movement of the shoulder pads 114, 116 when relatively rigid side tethers 172, 174, 176, 178 are utilized. When relatively elastic side tethers 172, 174, 176, 178 are utilized, the expected elongation under load may also be considered when determining an appropriate free length X2 for each of the side tethers 172, 174, 176, 178.
For football shoulder pads, about 40 degrees of rotation of the shoulder pads 114, 116 about the top tethers 140 may be sufficient to provide acceptable mobility of a wearer's arms and shoulders. In view of this, the free length X2 of each side tether 172, 174, 176, 178 may be between about 20% and about 30% of the length of the radial distance D from the side tether to an axis of rotation of the respective shoulder pad 116, 118 relative to the vest 112. For example, the, the free length X2 of a side tether 172, 174, 176, 178 may be about 35% of the length of the radial distance D from the side tether 172, 174, 176, 178 to an axis of rotation of the respective shoulder pad 116, 118 relative to the vest 112.

As shown in a cross-sectional detail view in
An opposing, second end 184 of the first side tether 172 may be routed around an anchor 188 of the shoulder pad 114. The second end 184 of the side tether 172 may be pulled after insertion through the anchor 188 until a desired free length X2 is achieved. The second end 184 of the side tether 172 may then be pressed against the first end 180 of the side tether 172 and the cooperative hook-and-loop fastener features may interlock.
In further embodiments, side tethers of a protective pad system 110 may comprise generally triangular pieces of textile 190 attaching the shoulder pads 114, 116, 118, 120 to the vest 112, as shown in
The vests and shoulder pads of the embodiments disclosed with reference to
As noted above, the corrugated member 210 is disposed adjacent to at least one foam member, and, according to one exemplary embodiment, between a foam upper member 220 and a foam lower member 230. According to one exemplary embodiment, the foam upper member 220 and the foam lower member 230 may be formed of similar or disparate foam materials to vary both energy absorption and user feel. As used in the present specification, the term “foam” shall be interpreted as any substance that is formed by a trapping of gas bubbles in a liquid or a solid, and shall include open and closed cell configurations. According to one exemplary embodiment, a polyurethane foam may be used to form the foam upper member 220 and the foam lower member 230. Alternatively, any number of or combinations of foams may be used to form the foam upper member 220 and a foam lower member 230 including, but in no way limited to as quantum foam, polyurethane foam (foam rubber), XPS foam, Polystyrene, phenolic, Syntactic foam, or any other manufactured foam. According to one exemplary embodiment, the foam upper member 220 and the foam lower member 230 are formed out of commercially available SHOCKtec™ Air2Gel Foam for enhanced impact dispersion. The present exemplary systems and methods were initially implemented using polyurethane foam manufactured by Utah Foam Products (Nephi, Utah) having varying densities and stiffness.
According to the present exemplary system and method, the foam upper member 220 and the foam lower member 230 may be formed around the corrugated member 210 via any number of foam forming methods including, but in no way limited to foaming the foam members in place around the corrugated member 210, pressing the foam around the corrugated member, extruding the foam to mate with the corrugated member, adhering the foam around the corrugated member, mechanically fastening the foam to the corrugated member, shaving or otherwise shaping the foam to mate with the corrugated member, or otherwise forming the foam as is known in the art.
Additionally, as noted above, the exemplary corrugated foam cell concept 200 includes a corrugated member 210 formed of a structural material disposed between the foam upper member 220 and the foam lower member 230. According to this exemplary embodiment, the corrugated member 210 may be formed of any number of thermoplastics or other bendable structural materials. While the present exemplary system is described in the context of the plate being formed of polypropylene or polycarbonate, any number of structural materials may be used to form the corrugated plate including, but in no way limited to polypropylene, polycarbonate including Lexan® from SABIC Innovative Plastics, polyamides such as nylon, and the like. According to one embodiment, Lexan® from SABIC Innovative Plastics is used to form the corrugated member 210 due to its fracture resistance and relatively large modulus of elasticity.
According to one exemplary embodiment, the corrugated member 210 is formed to exhibit a sinusoidal cross-sectional shape. As noted above, while the present exemplary system is described as having a corrugated member 210 with a repeating curved pattern that is similar to the curve of a sine function having crests and troughs. According to the present exemplary system and method, the corrugated member 210 the corrugations of the corrugated member 210 may assume any number of shape profiles to form the alternating grooves and ridges including, but in no way limited to, curves, triangles, substantially squared corners, stepped wave forms, and the like.
According to one exemplary embodiment, the use of a corrugated member 210 having the wave profile 300 illustrated in
According to one exemplary embodiment, the corrugated member 210 exhibits a nearly linear relationship between the applied force (F) and the deformation rates of the corrugated member for small deflections (approximately less than 35% of the original height and 20% of the original width). This linear relationship between the applied force (F) and the deformation rates allows for energy storage in the corrugated member 210 so that less of the impact force (F) is directly and immediately transferred to the body of the user as in the case of a flat plate.
In addition to dispersing energy imparted from an impact, the present exemplary pad plate system simultaneously provides selective support and mobility to the athlete incorporating the system. Specifically, according to one exemplary embodiment, the wave profile 300 of the plate provides a high level of stiffness in the direction parallel with the ridges, while providing flexibility in the direction transverse to the ridges of the sinusoidal plate. That is, the present exemplary configuration allows the plate to be bent and rotated about an axis that is perpendicular with the ridges. According to one exemplary embodiment, the direction and orientation of the ridges, and consequently the unidirectional flexure of the plate, can be selectively designed to allow for maximum mobility for football players without compromising safety. The direction, orientation, and shape of the ridges may be modified to maximize player flexibility and limb movement, thereby enhancing player safety and performance. According to one exemplary embodiment, the ridges may be designed and oriented to closely align with the natural movement of an athlete's body.
Additionally, the amplitude, wavelength, and thickness of the wave profile 300 of the corrugated member 210 can be varied to selectively introduce and design for areas of flexure. As illustrated in
The preceding description has been presented only to illustrate and describe embodiments of the presently disclosed protective pad systems and methods. It is not intended to be exhaustive or to limit the invention to any precise form disclosed. Many modifications and variations are possible in light of the above teachings.
