The cushioning element Fig. 2 is a cross section of the protector, and 0 comprises a toroid 6 of sponge or foam rubber Fig. 3 is a cross section illustrating a modified enclosed in a casing I of tough, durable rubber. construction. The casing l is applied to the sponge rubber in More specifically i designates the main body the same manner that the casing 4 is applied portion of a protector which in the present into the sponge rubber 3. The sponge rubber 6 stance is illustrated in the form of a football is completely sealed within the casing I and its In the form shown in Fig. 2 the inset 2 enablesplacement of a comparatively thick layer of sponge or foam rubber externally over the entire crown portion of the helmet. Fig. 3, however, illustrates the sponge rubber tapered so as to merge into the contour of the helmet. It will be understood, of course. that the sponge rubber 3a of Fig. 3 may be applied without fabric as shown in Fig. 2, or that the sponge rubber of Fig. 2 may be used with fabric as disclosed in Fig. 3.
Although specific embodiments of the invention have been illustrated and described, it will be understood that various changes may be made within the scope of the appended claims without departing from the spirit of the invention, and such changes are contemplated.
What is claimed is:
1. An athletic protector comprising a shelllike main body portion of comparatively stiff main body portion, said helmet having the crown portion inset with respect to theremainder of the contour thereof, a layer of spon e rubber secured to the crown portion externally thereof,
tour thereof, a layer of sponge rubber in said inset, and a casing of air impervious rubber overlying the sponge rubber and surface bonded to the sponge rubber and the helmet.-
3. An athletic protector comprising a shelllike main body portion of comparatively stiif main body portion, said helmet having the crown portion inset with respect to the remainder of the contour thereof, a layer of sponge rubber secured to crown portion externally thereof, a layer of open-mesh fabric overlying the sponge rubber, and a casing of air impervious rubber bonded to the sponge rubber through the interstices in said fabric.
4. An athletic protector comprising a shelllike main body portion of comparatively stiff main body portion, said helmet having the crown portion inset with respect to the remainder of the contour thereof, a layer of sponge rubber secured to the crown portion externally thereof, a casing of tough, durable rubber bonded to the exposed surface of said sponge rubber, and 8. padding within said body, said padding comprising a toroid of sponge rubber encased and sealed within a layer of air impervious rubber.
