Description

FIELD OF THE INVENTION

The invention relates generally to the field of protective headgear, and more particularly, to impact-resistant padding for protective headgear.

BACKGROUND OF THE INVENTION

Conventionally, participants in “contact” sports (e.g., wrestling, football, or rugby) wear protective headgear to cushion the force of impacts that are regularly received during those events. In recent years, the negative health effects of the impacts to the head experienced during such contact sports have been a matter of focus. These negative health effects can be diminished or minimized by effectively cushioning participants from the forces of impacts. Accordingly, improved structures, such as impact-resistant headgear, are desired to lessen the impact forces experienced by those participants.

DETAILED DESCRIPTION OF THE INVENTION

The embodiments of the invention described herein relate to a protective headgear system that incorporates an impact-resistant pad worn beneath a user's helmet to cushion the user's head. As used herein, the term “helmet” is not intended to be limited, but is meant to encompass any headgear worn for protection during an activity in which an impact to the head may occur. Additionally, as used herein, the term “impact-resistant” is intended to encompass any object that partially or fully lessens, diminishes, dissipates, or absorbs the mechanical force of an impact.

The exemplary protective headgear systems and apparatus disclosed herein are configured to lessen the force of an impact on the user's head. This makes them particularly suitable for use by participants in athletic activities, and particularly suitable for participants in traditional “contact” sports, such as wrestling, American football, or rugby, where high-force impacts may be commonly experienced. While the exemplary embodiments of the invention are described herein primarily with respect to wrestling, it will be understood that the invention is not so limited. Suitable applications for the impact-resistant pads of the present invention include, for example, military helmets, construction helmets, and/or other athletic activities. Other suitable applications will be readily understood by one of ordinary skill in the art from the description herein.

Referring now to the drawings, FIGS. 1A-1D illustrate an exemplary impact-resistant pad 100 in accordance with aspects of the present invention. Impact-resistant pad 100 may be worn by a user as part of a protective headgear system during an athletic activity, such as a wrestling match. As a general overview, impact-resistant pad 100 includes a top portion 120 and side portions 140 and 150. Additional details of impact-resistant pad 100 are described herein.

Top portion 120 is configured to be positioned covering a top of the user's head. As shown in FIGS. 1A-1D top portion 120 may be approximately circular, and is sized to cover substantially the entire top of the user's head. In an exemplary embodiment, top portion 120 includes a plurality of openings 122. Openings 122 desirably provide ventilation to the user's head during use of impact-resistant pad 100. As shown in FIG. 1D, openings 122 are formed around the periphery of top portion 120.

Side portions 140 and 150 extend downward from top portion 120. As used herein, the term “side portion” is not intended to mean that portions 140 and 150 are on the “side” of the user's head (as opposed to the front or back). To the contrary, portions 140 and 150 may be located on any side of the user's head. As shown in FIGS. 1B and 1C side portions 140 and 150 cover a front portion and a back portion of the user's head, respectively. As further illustrated in FIG. 1A, back portion 150 extends a greater distance from top portion 120 than front portion 140. This may be desirable in order to provide greater protection to the back of the user's head, and to prevent obstructing the user's view.

Side portions 140 and 150 are not directly connected to each other, as shown in FIG. 1A. In particular, a circumferential gap 160 is formed between side portions 140 and 150. This may be particularly desirable so that impact-resistant pad 100 may be worn by users of different head sizes. For example, when a user has a relatively small head, the gap 160 will be relatively narrow, and side portions 140 and 150 will sit close to each other (or possibly in contact with each other) when placed on the user's head. However, when a user has a relatively large head, the gap 160 will be relatively large, and side portions 140 and 150 will sit far from each other when placed on the user's head.

It will be understood that the number, shape, and size of side portions 140 and 150 in FIGS. 1A-1D is shown merely for the purposes of illustration, and is not intended to be limiting. Side portions 140 and 150 in different numbers or having different shapes or sizes may be used without departing from the scope of the present invention, as would be understood by one of ordinary skill in the art from the description herein.

Impact-resistant pad 100 is formed from materials designed to dissipate the force of impacts on the user's head. For example, impact-resistant pad 100 may include a layer of elastomeric material. The elastomeric material may provide impact-resistance by absorbing and dissipating the force of impacts laterally along the surface of the elastomeric material. In one exemplary embodiment, impact-resistant pad 100 consists of only a single layer of elastomeric material. In another exemplary embodiment, impact-resistant pad 100 comprises two or more layers of elastomeric material. Impact-resistant pad 100 may include the layers of elastomeric material directly adjacent each other, or in a more preferred embodiment, may include a layer of high tensile strength fibrous material between the layers of elastomeric material.

Suitable materials for forming the elastomeric layer(s) include, but are not limited to, urethane rubbers, silicone rubbers, nitrile rubbers, butyl rubbers, acrylic rubbers, natural rubbers, styrene-butadiene rubbers, and the like. In general, any suitable elastomer material can be used to form the above-described elastomeric layers without departing from the scope of the present invention. Suitable materials for forming the layer of high tensile strength fibrous material include, but are not limited to, aramid fibers, fiberglass, or other high tensile strength fibers. The fibers may be woven to form a cloth layer that is disposed between and generally separates the opposing elastomeric layers. The high tensile strength fibrous material layer may desirably block and redirect impact energy that passes through one of the elastomeric layers. Additional description of materials for forming the impact-resistant pad may be found in co-pending U.S. patent application Ser. No. 13/331,004, the contents of which are incorporated herein by reference in their entirety.

Impact-resistant pad 100 is unconnected to any supporting structure. As will be discussed in further detail herein, impact-resistant pad 100 is configured to be worn under a helmet. To this end, impact-resistant pad 100 is desirably thin. In an exemplary embodiment, impact-resistant pad 100 has a thickness of no greater than approximately 13 mm, and even more preferably, a thickness of no greater than approximately 3 mm. The thickness of impact-resistant pad 100 may be selected based on a number of factors, including for example the type of helmet, the desired level of impact protection, and the type of material encasing the pad (such as moisture-wicking, moisture-absorbent, cloth, or neoprene).

FIGS. 2A-2C illustrate an exemplary protective headgear system 200 in accordance with aspects of the present invention. Protective headgear system 200 may be worn by a user during an athletic activity, such as a wrestling match. As a general overview, protective headgear system 200 includes an impact-resistant pad 220 and a helmet 240. Additional details of protective headgear system 200 are described herein.

Impact-resistant pad 220 is formed from materials designed to dissipate the force of impacts on the user's head. In an exemplary embodiment, impact-resistant pad 220 is an impact-resistant pad substantially as described above with respect to impact-resistant pad 100. In particular, impact-resistant pad 220 includes a top portion 222 configured to be positioned covering a top of the user's head, and side portions 224 and 225 extending downward from top portion 222. Side portions 224 and 225 are not directly connected to each other, and define a circumferential gap (not shown) therebetween.

Helmet 240 is configured to be positioned on a user's head overtop of impact-resistant pad 220. Helmet 240 is unconnected to impact-resistant pad 220. When helmet 240 is positioned overtop of impact-resistant pad 220, helmet 240 covers the circumferential. In an exemplary embodiment, helmet 240 comprises conventional wrestling headgear, as shown in FIGS. 2A-2C. Helmet 240 includes a plurality of straps 242 for securing helmet 240 to the user's head. Straps 242 extend over top portion 222 of impact-resistant pad 220. Impact-resistant pad 220 may include guide portions (not shown) for receiving and properly positioning straps 242 of helmet 240.

It will be understood by one of ordinary skill in the art that helmet 240 is not limited to the embodiment shown in FIGS. 2A-2CFIG. 3 illustrates another exemplary protective headgear system 300 in accordance with aspects of the present invention. As a general overview, protective headgear system 300 includes an impact-resistant pad 320 and a helmet 340, as shown in FIG. 3. Helmet 340 is configured to completely cover the user's head. This may be desirable in order to provide an additional layer of impact-resistance on top of impact-resistant pad 320. The size of helmet 340 is selected such that helmet 340 can accommodate impact-resistant pad 320 therein while still being securely positioned on the user's head. Suitable helmets 340 for use with the present invention will be known to one of ordinary skill in the art from the description herein.

FIGS. 4A-4C illustrate an exemplary protective headgear system 400 in accordance with aspects of the present invention. Protective headgear system 400 may be worn by a user during an athletic activity, such as skiing or snowboarding. As a general overview, protective headgear system 400 includes an impact-resistant pad 420 and a deflection layer 440. Additional details of protective headgear system 400 are described herein.

Impact-resistant pad 420 is formed from materials designed to dissipate the force of impacts on the user's head. In an exemplary embodiment, impact-resistant pad 420 is an impact-resistant pad substantially as described above with respect to impact-resistant pad 100. In another exemplary embodiment, impact-resistant pad 400 is a pad substantially as described with respect to the spacing pads disclosed in U.S. patent application Ser. No. 13/740,443. In particular, impact-resistant pad 420 includes a top portion 422 configured to be positioned covering a top of the user's head, and extending portions 424 extending downward from top portion 422. Extending portions 424 are not directly connected to each other, and define a circumferential gap (not shown) therebetween.

As shown in FIG. 4B, extending portions 424 project outward at regular intervals from top portion 422. Extending portions 424 have end portions having a greater width than the remainder of the respective extending portion 424. The wider end portions of impact-resistant pad 420 may be desirable in order to provide a large base for deflection layer 440. Additionally, as shown in FIG. 4B, the extending portion 424a configured to be positioned adjacent a side of the user's head has a greater width than the extending portions 424b configured to be positioned adjacent a front of the user's head, and the extending portions 424c configured to be positioned adjacent a rear of the user's head.

The shapes and sizes of extending portions 424 may also be dependent on the configuration of deflection layer 440, as set forth below.

As shown in FIGS. 4B and 4C, the varying lengths of extending portions 424 may be selected to correspond to a peripheral contour of deflection layer 440. In other words, if the periphery of deflection layer 440 has a varying contour, the lengths of extending portions 424 may be selected such that, when deflection layer 440 is positioned overtop of impact-resistant pad 420, the end of each extending portion 424 projects to within a specified distance of the periphery of deflection layer 440. In an exemplary embodiment, extending portions 424 project to within 0.125-2.0 inches of the periphery of deflection layer 440. Additionally, the extending portions 424c configured to be positioned adjacent a rear of the user's head may have a greater length than the extending portions 424b configured to be positioned adjacent a front of the user's head.

It will be understood that the number, shape, and size of extending portions 440 in FIG. 4B is shown merely for the purposes of illustration, and is not intended to be limiting. Extending portions 424 in different numbers or having different shapes or sizes may be used without departing from the scope of the present invention, as would be understood by one of ordinary skill in the art from the description herein.

Impact-resistant pad 420 is formed from materials designed to dissipate the force of impacts on the user's head. Suitable materials for forming impact-resistant pad 420 include any of the materials described above with respect to impact-resistant pad 100.

Impact-resistant pad 420 may not be adapted to be coupled to the interior of deflection layer 440. In other words, impact-resistant pad 420 may remain unconnected to deflection layer 440 (or from any other component that is connected to deflection layer 440). This enables relative movement between impact-resistant pad 420 and deflection layer 440, which may be important to assist in dissipation of the force from impacts, as explained in further detail below with respect to deflection layer 440.

Alternatively, impact-resistant pad 420 may be coupled to deflection layer 440. In an exemplary embodiment, impact-resistant pad 420 can be sewn to each of the plates that make up deflection layer 440. Because impact-resistant pad 420 is more flexible than deflection layer 440, such an attachment would still enable relative movement of the plates that make up deflection layer 440.

Deflection layer 440 is configured to be positioned over impact-resistant pad 420. Deflection layer 440 is formed from a material that is less flexible (i.e. stiffer) than impact-resistant pad 420. This enables the hard surface of deflection layer 440 to deflect a portion of the force from impacts along a surface thereof, rather than transmitting that force through deflection layer 440 to impact-resistant pad 420. In other words, it assists in converting forces from impacts into tangential forces (which propagate along the surface) as opposed to normal forces (which propagate through the surface to the user's head). In an exemplary embodiment, deflection layer 440 comprises polycarbonate material.

Deflection layer 440 may have a shape corresponding to the shape of impact-resistant pad 420, such that the deflection layer 440 completely covers at least a portion of the circumferential gap between the extending portions 424 when it is positioned overtop of impact-resistant pad 420.

As set forth above, deflection layer 440 may not be coupled to the exterior of impact-resistant pad 420. This creates a “slip plane” between deflection layer 440 and impact-resistant pad 420, and enables relative movement between the two components. Put another way, this allows independent movement of the user's head (with which impact-resistant pad 420 is in contact) and deflection layer 440.

As shown in FIGS. 4A and 4C, deflection layer 440 comprises a plurality of deflection plates 442a, 442b, 442c. Deflection plates 442a, 442b, 442c lack a rigid connection between one another. In other words, deflection plates 442a, 442b, 442c can move relative to one another. This may be desirable in order to assist in dissipating the force of impacts. This may also be desirable in order to provide an adjustable, contoured fit to the user's head.

As shown in FIG. 4A, deflection plate 442a is a front deflection plate, configured to be positioned adjacent a front of the user's head. Deflection plate 442b is a middle deflection plate, configured to be positioned adjacent a middle of the user's head. Deflection plate 442c is a rear deflection plate, configured to be positioned adjacent a rear of the user's head. Deflection plates 442a, 442b, 442c are shaped and sized to cover substantially all of the respective portions of the user's head to which they correspond. Additionally, as shown in FIGS. 4A and 4C, deflection plates 442a, 442b, 442c are contoured to maintain a predetermined distance between one another, in order to maintain the lack of rigid connection therebetween.

As shown in FIG. 4A, deflection layer 440 may include one or more straps 444 connecting between the plurality of deflection plates 442a, 442b, 442c. In an exemplary embodiment, deflection layer 440 comprises a first strap 444a connecting between front deflection plate 442a and middle deflection plate 442b, and a second strap 444b connecting between middle deflection plate 442b and rear deflection plate 442c. This desirably enables a user to pull on straps 444a and 444b (or on another strap connected to those straps) in order to tighten or adjust the positioned of system 400 on the user's head.

Protective headgear system 400 may further include a layer of high tensile strength fibrous material between impact-resistant pad 420 and deflection layer 440. The layer of high tensile strength fibrous material may be connected to either impact-resistant pad 420 or deflection layer 440. In an exemplary embodiment, the layer of high tensile strength fibrous material comprises aramid fibers.

Protective headgear system 400 may be configured to be worn under another piece of headgear, such as an article of clothing like a knit cap or a baseball cap, hat, or such as athletic equipment like a face mask, an eye shield, or goggles. To this end, impact-resistant pad 420 and deflection layer 440 are desirably thin. In an exemplary embodiment, protective headgear system 400 has a thickness of between approximately ¼ inch and ¾ inch, but in most case less than 1 (one) inch. In particular, in an exemplary embodiment, impact-resistant pad 420 has a thickness of between approximately ⅛ inch and ⅝ inch, and deflection layer 440 has a thickness of between approximately 1/16 inch and ¼ inch. Using such thin components may enable protective headgear system 400 to be worn very close to the user's head, thereby increasing dynamics, improving balance, and reducing weight. In another exemplary embodiment, protective headgear system 400 may be contoured to accommodate another piece of headgear, such as goggles, for the user to wear overtop of protective headgear system 400.

As set forth above, as shown in FIGS. 4A and 4C, deflection plates 442a, 442b, 442c are contoured to maintain a predetermined distance between one another, in order to maintain the lack of rigid connection therebetween. Nonetheless, in order to protect against impacts occurring at the location of these gaps in deflection layer 440, it may be desirable that the protective headgear system include additional protection at these locations.

FIGS. 5A and 5B illustrate another exemplary protective headgear system 500 in accordance with aspects of the present invention. Protective headgear system 500 is substantially the same as protective headgear system 400 except as set forth below.

System 500 includes deflection layer 540, which is configured to be positioned over an impact-resistant pad (not shown). As shown in FIGS. 5A and 5B, deflection layer 540 comprises a plurality of deflection plates 542a, 542b, 542c. Deflection plates 542a, 542b, 542c lack a rigid connection between one another. As shown in FIG. 5A, deflection plate 542a is a front deflection plate, configured to be positioned adjacent a front of the user's head. Deflection plate 542b is a middle deflection plate, configured to be positioned adjacent a middle of the user's head. Deflection plate 542c is a rear deflection plate, configured to be positioned adjacent a rear of the user's head. Deflection plates 542a, 542b, 542c are shaped and sized to cover substantially all of the respective portions of the user's head to which they correspond.

As shown in FIG. 5B, deflection plates 542a and 542c each include a respective ledge portion 546a and 546c. Ledge portions 546a and 546c are configured such that they extend beneath deflection plate 542b when deflection layer 540 is positioned on the user's head. Ledge portions 546a and 546c desirably protect against impacts occurring at the location of gaps between deflection plates 542, 542b, 542c, while maintaining the lack of rigid connection between deflection plates 542, 542b, 542c.

The number and shape of the plates that constitute the deflection layers in FIGS. 4A-5B are illustrative, and is not intended to be limited. Protective headgear systems 400 and 500 may include more or fewer deflection plates as desired based on the intended use of protective headgear systems 400 and 500.

FIG. 6 illustrates an exemplary protective headgear system 600 in accordance with aspects of the present invention.
