DESCRIPTION OF PREFERRED EMBODIMENTS Referring now again to the drawings, there is illustrated a helmet 10 which is adapted to protect the head of the wearer in a sporting event, such as football. The helmet may be comprised of a thin shell formed of a lightweight metallic material, such as, for instance, aluminum. However, other conventional materials can be utilized for the aforementioned shell of the helmet. A suitable covering of plastic or nylon material, or any other suitable material, may be disposed on the exterior surface of the shell and beading or edging material may be applied along the peripheral edge of the shell in the conventional well-known manner. Such edging or beading material may be formed of any suitable material such as, for instance, elastomeric plastics or rubber. The shell may be provided with suitable openings or holes (not shown) in the side portions thereof in the vicinity of the ears of the wearer, for facilitating hearing by the wearer.
The padding assembly 14 with which the present invention is particularly concerned, is mounted on the interior surface of the shell so as to space the latter from the head of wearer to user.
The padding assembly may comprise a top or crown portion or member 16, a frontal portion or member 18, a rear portion or member 20, and side portions or members 22, which when inflated are operable to cushion the head of the wearer from impacts, and to snugly hold the helmet to the head of the wearer in a customlike fit.
The padding is illustrated in inflated condition and the crown or top portion 16 has a valving mechanism 24 (FIGS. 2 and 3) mounted thereon, or coacting therewith, for insertion of pressurized fluid into the inflatable padding. This insertion of pressurized fluid is preferably accomplished by means of an inflating needle 26 of conventional type, which is adapted to be inserted into the self-sealing valve and to direct pressurized fluid such as air thereinto.
Frontal member or portion 18 of the padding, in the embodiment illustrated, comprises three individual cells 28, 28a and 2812 which are interconnected or communicated with one another by means of relatively short passageway sections 30, for transfer of pressurized fluid therebetween. Rearward portion or member of the inflatable padding likewise, in the embodiment illustrated, is formed of three individual cells or bags 30, 30a and 301), which are interconnected by relatively short passageway sections 32 for transfer of fluid pressure therebetween.
The side portions or members 22 are each formed of a plurality of individual cells, the upper 34, 34a of which are in the form of generally kidney-shaped configurations, and the lower 36 of which is of a generally lazy U-shaped configuration, all of which are interconnected with conduit or passageway sections 38 for transfer of fluid pressure therebetween.
The top or crown portion 16 of the inflatable padding comprises in the embodiment illustrated a single generally egg-shaped (when inflated) cell, and with the single cell mounting the aforementioned valve means 24 thereon. Valve means 24 is coupled as by means of elongated flexible conduit or arm members 40 radiating out from the valve member to be coupled to the respective of the side, frontal and rearward portions of the inflatable padding.
Ascan be seen from the drawings, the inflatable padding may be readily constructed of heat-scalable plastic material, many of which are known in the art, such as, for instance, polyvinyl materials. Each section or member of the inflatable padding may be formed from a base sheet or section 44 (FIGS. 4, 5 and 7) and a cover or pillow sheet 46 which are joined along the seam 48. The aforementioned radiating conduit sections 40 can be unitarily formed from the base and pillow sheets, for facilitating the manufacture of the inflatable padding. As can be readily seen in FIGS. 4 and 7, when the respective padding section or member is inflated, the base sheet which is adapted for attachment to the inner surface of the helmet proper by any suitable means, such as for instance adhesives, mating tapes of Velcro, or mechanical fasteners, is extended a considerably lesser amount than is the inwardly facing cushion or pillow sheet of the respective portion of the padding.
As can be seen in FIGS. 4, S and 7 each of the members l6, 18, 20 and 22 preferably has interiorly thereof a cushioning pad 49 formed of suitable resilient material, such as for instance sponge rubber or flexible polyurethane foam. Each pad 49 occupies a portion of the respective cell of the associated member and is preferably comprised ofa base layer 490 of a denser, less flexible nature, and a facing layer 4917 ofa lighter, softer nature, with the softer layer being disposed closest to the wearers head. The pads 49 may be porous and do not restrict the transfer of fluid between the interconnected cells.
Referring now in particular to FIGS. 2 and 3, the aforementioned valve 24 for selective inflation of certain of the padding portions or members with respect to other of the padding portions comprises a head portion 50 and a separable base portion 52. The valve is preferably formed of soft elastomeric material, such as for instance, the conventional self-sealing rubber or plastic materials from which valve mechanisms for sporting goods such as footballs are conventionally made. The head portion is adapted to communicate through an opening 54 in helmet shell 10 of the head gear (FIG. 2) with the exterior of the head gear, and at the crown portion thereof (FIG. 1). The upper embossment or crown 56 of the head 50 of the valve mechanism is adapted to extend into the opening 54 for ready accessibility to the inflating needle 26. The embossment or crown 56 is preferably provided with sloping surfaces 56a coacting with complementary surfaces in opening 54 in the helmet shell, for facilitating securing the embossment to the shell 10 and as by means of an adhesive.
The head section 50 has a generally flat undersurface 58 which is adapted for mating sealed coaction with flat surface 60 on the base section of the valve mechanism. Complementary projection and recess means 62, 62a may be provided for locating the base section of the valve mechanism with respect to the head section. Base section 52 includes chamber 64 located generally centrally thereof and from which laterally extending, opposed passageways 66 extend, for communication with the aforementioned elongated conduits 40 and as by means of integral collar portion 68, which surrounds the base section 52 of the valving mechanism in sealed relation therewith and which provides communication of the aforementioned passageways 66 with the conduit members 40. As can be seen, the base section 52 includes a flange portion 72 which overlies the defining upper wall of top cushion member 16 and which is bonded or sealed thereto. Likewise, head section 50 of the valve may include a peripheral flange 74 which is sealed to the juncture of conduit arms 40 to aid in providing an air tight high strength assembly of the valve mechanism to the padding cushion structure.
As can be seen in FIG. 2, insertion of the inflating needle 26 through the self-sealing needle receiving passage 76 in head section 50 of the valve mechanism 24, communicates the fluid discharge end of the needle with the chamber 64 in the valve, and upon application of pressurized fluid to the entry end of the needle, causes fluid to be distributed to the chamber 64, out passages 66, through the interior of collar 68, and into communication with the conduit arms 40, thus causing substantially simultaneous inflation of the front, rear, and side cushion members 18, and 22. With the head gear positioned on the head of the wearer, the substantially simultaneous inflation of the side cushion members together with the inflation of the front and rear cushion members causes a uniform fit of the helmet to the head of the wearer.
Referring to FIG. 3, when the needle is forced downwardly past chamber 64 into the self-sealing needle receiving passage 78 in base section 52 of the valve mechanism, the discharge end of the needle passes into the interior of top cushion member 16. Application of fluid pressure to the top cushion member 16, causes inflation of the latter, and thus positions the helmet vertically with respect to the head of the wearer. Withdrawal of the needle from the valve mechanism permits the valve mechanism to self-seal, and thus the fluid is retained in the cushioning members 16 through 22. It is preferable to inflate top member 16 first, to position the helmet with respect to the head of the wearer, and then to cause inflation of the front, back and side cushion members, although the reverse order can be followed.
From the foregoing discussion and accompanying drawings it will be seen that there is provided a novel inflatable padding adapted for attachment to the interior surface of a helmet for protecting the head of the wearer, and with the padding embodying valve means that enables the selective inflation of some of the members with respect to the other of the members with substantially simultaneous inflation of certain of the members, and an arrangement which provides for a snug custom-like fit of the helmet to the head of the wearer, to give the latter optimum cushioning protection. The invention also provides a padding in accordance with the aforegoing in combination with a lightweight helmet for providing for optimum protection to the head of the wearer.
