Race Car Driver Vest

Not applicable.

Not applicable.

The injuries of race car drivers during races are well known in the art. Many types of safety apparatus have been designed to protect the race car driver so that injuries to the race car driver are minimized during crashes. For example, seat belt straps extending across the shoulders, and waist of the race car driver are currently in use to protect the race car driver from injury. In addition, race car seats are molded to be disposed about the trunk of the race car driver when the race car driver assumes a seated position to prevent lateral movement of the race car driver.

During a frontal impact of the race car with another race car, the prior art seat belt straps, and molded seats may function to sufficiently protect the race car driver.

However, if the race car hits a wall or other substantially immoveable object the race car driver can be ejected from the seat with such force that the seat belts overlying the race car driver's shoulder blades can break the race car driver's collar bones and/or rib cage. During a side impact, the race car driver is thrown toward or away from the race car's door. The lateral force placed on the race car driver during a side impact can cause the seat belts and/or the molded car seat to break the race car driver's shoulder blades, clavicles and/or collar bones.

To protect themselves against such injuries, race car drivers have worn football pads, such as rib pads, knee pads, shoulder pads and hip pads. In addition, such race car drivers have also worn bull riding vests to protect themselves. The comfort of the protective devices worn by the race car driver is an extremely important consideration because of the heat build up within a race car. The football pads and the bull riding vest have typically not functioned adequately to protect the race car driver from injury, and also may make the race car driver uncomfortable during the race. For example, the bull riding vest did not cover and protect the shoulder blades entirely thereby leading to injury in the event there is a car crash. In addition, such football pads and bull riding vests were generally inflexible and retained heat thereby preventing the race car driver from sitting comfortably in the seat of the race car. Moreover, the bull riding vest had a lower portion which extended over the tail bone of the individual thereby making the race car driver even more uncomfortable.

Due to the uncomfortable nature of the football pads and bull riding vest, some race car drivers elected not to wear these protective devices even though these devices did afford some protection. Thus, there is a need for a vest which more adequately protects the race car driver while also being more comfortable for the race car driver to wear during races. It is to such a novel vest that the present invention is directed.

Broadly, the present invention relates to improvements in vests adapted to be worn by an individual, such as a race car driver. The vest includes a cushioning assembly. The cushioning assembly is adapted to extend about the chest cavity, collar bones, sternum, shoulder blades, clavicles and rib area of the individual to prevent injury to the individual when impact is applied thereto. The cushioning assembly is also constructed to permit air to circulate about and cool the portions of the individual covered by the cushioning assembly. The cushioning assembly typically extends downwardly from about the hollow of the throat of the individual to near the midriff of the individual whereby the individual can assume a seated position in a seat, such as a molded race car seat without substantial interference from the cushioning assembly.

In one aspect, the vest is provided without portions extending below the midriff of the individual, so that when the individual assumes the seated position, the cushion assembly does not engage the legs or the tail bone of the individual.

These and other aspects of the invention will be more fully understood by referring to the following detailed description and accompanying drawings.

The frontal cushioning assembly 104 is provided with a length 126 (FIG. 8) extending between the lowermost portion of the neck receiving opening 112 and the bottom end 110 thereof. When the frontal cushioning assembly 104 is worn by the individual, a portion 128 of the frontal cushioning assembly 104, which is substantially adjacent the neck receiving opening 112, is disposed adjacent the hollow of the individual's throat, and the frontal cushioning assembly 104 extends downwardly therefrom to the bottom end 110, which is disposed adjacent to the individual's midriff, such that the frontal cushioning assembly 104 effectively covers the individual's chest cavity.

The first side section 120 and the second side section 122 are sized and adapted to extend below the individual's arms to effectively cover the individual's rib cage when the frontal cushioning assembly 104 is being worn by the individual.

The frontal cushioning assembly 104 includes a cushioning member 132 which is formed of a flexible, yet resilient energy absorbing, or dissipating material so as to be comfortable when worn by the individual, yet capable of preventing or reducing injury to the individual when impact is applied thereto. In one embodiment, the cushioning member 132 can be constructed of a closed cell crosslinked polyethylene foam, such as three laminated layers of Voltek Volara, from outside to inside Volara 4E, Volara 6E, Volara 4E. The cushioning member 132 can be provided as a unitary structure, if desired.

The frontal cushioning assembly 104 is provided with an outer shell 134 which is disposed about the cushioning member 132 to substantially encompass the cushioning member 132. The outer shell 134 can be constructed of a mesh-like material defining a plurality of spatially disposed openings to permit air to circulate through the outer shell 134. Stitching 136 can be provided through adjacently disposed portions of the outer shell 134 around the perimeter of the frontal cushioning assembly 104 so as to maintain the outer shell 134 about the cushioning member 132.

The cushioning member 132 has an outer side 138 (as best shown in FIG. 8), and an inner side 140 (as best shown in FIG. 10). The outer side 138 of the cushioning member 132 is constructed to have a smooth texture thereon. In contrast, a plurality of air receiving channels 142 are formed in the inner side 140 of the cushioning member 132 to define a plurality of cushion member ridges 144 on the inner side 140 of the cushioning member 132.

The cushion member ridges 144, and the air receiving channels 142 defined therebetween function to permit air to pass through the air receiving channels 142 to circulate about and cool the portions of the individual covered by the cushioning member 132, and to provide the cushioning member 132 with added flexibility.

The cushion member ridges 144 can be characterized as having a central portion 146, a first medial portion 148, a second medial portion 150, a first strap portion 152 and a second strap portion 154. The central portion 146 is disposed generally centrally in the cushioning member 132, and extends from the lowermost portion of the neck receiving opening 112, to near the bottom end 110 of the frontal cushioning assembly 104. The first medial portion 148, and the second medial portion 150 of the cushion member ridges 144 extend on respective opposite sides of the central portion 146, generally from the lowermost portion of the neck receiving opening 112 toward the bottom end 110 of the frontal cushioning assembly 104. The first strap portion 152 and the second strap portion 154 of the cushion member ridges 144 extend into the respective first and second wing portions 114 and 116 of the frontal cushioning assembly 104.

As best shown in FIG. 10, the cushion member ridges 144 formed in the first and second medial portions 148 and 150 are angled relative to the cushion member ridges 144 formed in the central portion 146 such that the cushion member ridges 144 in the first and second medial portions 148 and 150 permit the cushioning member 132 to readily form about the pectoral regions of the individual when the frontal cushioning assembly 104 is being worn by the individual.

As best shown in FIG. 12, the cushion member ridges 144 in the central portion 146 have a thickness extending between the outer side 138 and the inner side 140 of the cushioning member 132, which is greater than the thickness of the remainder of the cushioning member 132 so that the inner side 140 forms to the contours of the individual's chest while maintaining the outer side 138 of the cushioning member 132 in a substantially planar relationship for a purpose to be described hereinafter.

To enhance the flexibility and comfort of the first and second wing portions 114 and 116 as the first and second wing portions 114 and 116 are disposed about the individual's shoulders, the cushion member ridges 144 in the first and second strap portions 152 and 154, are angled in an opposite direction with respect to the angle of the cushion member ridges 144 in the first and second medial portions 148 and 150.

Formed in the outer shell 134, generally adjacent the outer side 138 of the cushioning member 132, is a pocket 160 adapted to receive a rigid, yet resilient impact receiving member 162 for protecting the individual's chest from impact with the steering wheel of a race car, for example. The impact receiving member 162 can be provided with a generally planar configuration so that the impact receiving member 162 conforms to the contours of the outer side 138 of the cushioning member 132. The impact receiving member 162 can be constructed of a resilient plastic material.

Referring now to FIGS. 9 and 11, the rear cushioning assembly 106 will now be described. The rear cushioning assembly 106 is sized, dimensioned and adapted to be disposable about the back of the individual so as to cover the individual's shoulder blades and to prevent or reduce injury thereto upon impact to the rear cushioning assembly 106.

The rear cushioning assembly 106 is provided with a top end 174 and a bottom end 176. The rear cushioning assembly 106 is provided with a central portion 178. A first wing portion 180, and a second wing portion 182 extend upwardly from the central portion 178 so as to define a neck receiving opening 184 positionable about at least a portion of the individual's neck so that the first and second wing portions 180 and 182 are disposable over at least a portion of the individual's shoulders so as to protect the individual's shoulders and clavicles from injury when force is applied to the first and second wing portions 180 and 182. To prevent injury to the individual's shoulder and clavicles from impact with seat belts and/or safety harnesses in a race car, for example, the first and second wing portions 180 and 182 desirably have a width which is greater than the width of the seat belts and/or safety harnesses.

The rear cushioning assembly 106 includes oppositely disposed first and second extension members 186 and 188 extending from the central portion 178. As best shown in FIG. 8, the first and second extension members 186 and 188 are sized and dimensioned so as to be wrapped underneath the individual's arms so that the first and second extension members 186 and 188 overlap over the first side section 120 and the second side section 122 of the frontal cushioning assembly 104. In other words, the first and second extension members 186 and 188 are wrapped underneath the individual's arms so as to be disposable generally adjacent the front of the individual.

The rear cushioning assembly 106 includes an outer shell 194 defining a plurality of spacially disposed openings 196 therein so as to permit air to circulate through the openings 196. The outer shell 194 can be constructed of a mesh-like material, for example. The outer shell 194 defines a pocket 198 adapted to receive a cushioning member 200 therein. Stitching 202 can be provided around the perimeter of the cushioning member 200 to maintain the cushioning member 200 in the outer shell 194. The cushioning member 200 extends downwardly from the top end 174 of the rear cushioning assembly 106, to terminate a distance 203 from the bottom end 176 of the rear cushioning assembly 1015, and above the first and second extension members 186 and 188 so that the cushioning member 200 extends over the individual's shoulders, and the individual's upper back to a location just below the individual's shoulder blades when the rear cushioning assembly 106 is being worn by the individual.

The cushioning member 200 is provided with an outer side 204, and an inner side 206. The cushioning member 200 defines a fairly substantially flat contiguous surface on the outer side 204, and a plurality of spacially disposed cushion member ridges 208 on the inner side 206 thereof. The cushion member ridges 208 define a plurality of air receiving channels 210 therebetween so as to permit air to readily circulate through the openings 196 and the outer shell 194, and into the air receiving channels 210 so as to cool the portions of the individual covered by the cushioning member 200. It should also be noted that the spacially disposed cushion member ridges 208 enhance the inherent flexibility in the cushioning member 200 so as to make the rear cushioning assembly 106 more comfortable to the individual when being worn thereby.

The cushion member ridges 208 can be characterized as having a central portion 212, and a pair of oppositely disposed outer portions 214 disposed on either side of the central portion 212. Although only one half of the rear cushioning assembly 106 is shown in FIG. 11 for purposes of clarity, it should be understood that the rear cushioning assembly 106 is generally symmetrical in configuration.

The cushion member ridges 208 in the outer portion 214 are angled relative to the cushion member ridges 208 in the central portion 212 so as to permit the cushioning member 200 to readily form about the individual's upper back and shoulders.

The vest 100 is further provided with a first connector assembly 220 for connecting the respective first and second wing portions 114 and 116 of the frontal cushioning assembly 104 to the first and second wing portions 180 and 182 of the rear cushioning assembly 106. The vest 100 is also provided with a second connector assembly 224 for connecting the respective first and second side sections 120 and 122 of the frontal cushioning assembly 104 to the first and second extension members 186 and 188 of the rear cushioning assembly 106. The first connection assembly 220 is adapted to permit the amount of overlap between the first and second wing portions 114 and 116 and the respective first and second wing portions 180 and 182 to be adjusted so that the height, and the size of the neck receiving openings 112 and 184 of the vest 100 can be adjusted. In one embodiment, the first connector assembly 220 can be a VELCRO.RTM. brand connector assembly disposed on respective portions of the first and second wing portions 114 and 116 and the first and second wing portions 180 and 182 (as shown in FIG. 8).

The second connector assembly 224 is adapted to permit the amount of overlap between the first and second side sections 120 and 122, and the respective first and second extension members 186 and 188 to be adjusted so that the diameter of the vest 100 can be adjusted to fit individuals of various sizes. In one embodiment, the second connector assembly 224 can be a VELCRO.RTM. brand connector assembly.

In use, the vest 100 is provided with the first connector assembly 220 connecting the frontal cushioning assembly 104, to the rear cushioning assembly 106 such that the neck receiving openings 112 and 184 are spaced a distance apart to receive the individual's head. Initially, the lower portions of the frontal and rear cushioning assemblies 104 and 106 are not connected by the second connector assembly 224.

The individual's head is disposed through the neck receiving openings 112 and 184 defined by the frontal and rear cushioning assemblies 104 and 106 such that the first and second wing portions 114 and 116 of the frontal cushioning assembly 104, and the first and second wing portions 180 and 182 of the rear cushioning assembly 106 are disposed about the individual's shoulders, the frontal cushioning assembly 104 covers the individual's chest, and the rear cushioning assembly 106 covers the individual's upper back. The first connector assembly 220 is then adjusted so that the frontal and rear cushioning assemblies 104 and 106 are disposed loosely about the individual's neck.

Then, the second connector assembly 224 is utilized to connect the lower ends of the frontal and rear cushioning assemblies 104 and 106 so that the cushioning assembly 102 is disposed snugly about the individual's torso. In this position, the cushioning assembly 102 functions to prevent or reduce injury to the individual from impact applied to the cushioning assembly 102. In the instance when the vest 100 is to be utilized as a race car driver vest, the individual then sits in the seat of the race car, and the seat belts and other safety harnesses are disposed snugly about the individual. The seat belts and other safety harnesses in a race car are well known and no more comments are deemed necessary to teach one of ordinary skill in the art to make or use the seat belts and other safety harnesses.

Thus, it can be seen that the vests 10 and 100, as constructed in accordance with the present invention, serve to prevent or reduce injury to the individual when impact is applied thereto, while being comfortable to wear by the individual. In addition, the vests 10 and 100 serve to cover the portions of the individual which are most likely to be engaged by the seat belts, safety harnesses or molded car seat in a race car to prevent or reduce injury thereto during a race car crash.

Although the vests 10 and 100 have been described herein as to be worn by a race car driver who is to be seated in a molded race car seat and maintained therein by safety harnesses and straps, it should be understood that the vests 10 and 100 of the present invention can be suitable for other uses, such as any sports or leisure activity, which can benefit from chest protection.

Changes may be made in the embodiments of the invention described herein, or in the parts or the elements of the embodiments described herein or in the steps or sequence of steps of the methods described herein. Without departing from the spirit and/or the scope of the invention as defined in the following claims.
