Compressive bump cap

Abstract

A compressive bump cap is provided which has an inner protection system. The compressive bump cap is stretchable between a relaxed configuration and an expanded configuration. The expanding configuration has a convex shape such that it can conform to a head of a wearer.

What is claimed is: 
     
         1 . A compressive bump cap, comprising:
 a multi-layer sidewall, wherein the multi-layer sidewall forms a dome, wherein the dome defines a circular opening for a head of a wearer, and wherein the multi-layered sidewall comprises:
 an inner stretchable fabric layer; 
 an outer stretchable fabric layer; and 
 an inner protection system positioned in a pocket defined by the inner stretchable fabric layer and the outer stretchable fabric layer, wherein the inner protection system comprises a rigid layer and a padding layer; and 
   wherein the inner stretchable fabric layer and the outer stretchable fabric layer are expandable from a relaxed state to an expanded state.   
     
     
         2 . The compressive bump cap of  claim 1 , wherein the rigid layer is immediately adjacent to the outer stretchable fabric layer and the padding layer is immediately adjacent to the inner stretchable fabric layer. 
     
     
         3 . The compressive bump cap of  claim 1 , wherein the rigid layer comprises a molded plastic shell. 
     
     
         4 . The compressive bump cap of  claim 1 , wherein the padding layer is non-removably coupled to the rigid layer. 
     
     
         5 . The compressive bump cap of  claim 1 , wherein the padding layer is removably coupled to the rigid layer. 
     
     
         6 . The compressive bump cap of  claim 1 , wherein the inner protection system is non-removably positioned in the pocket defined by the inner stretchable fabric layer and the outer stretchable fabric layer. 
     
     
         7 . The compressive bump cap of  claim 6 , wherein the rigid layer is adhered to an inner surface of the outer stretchable fabric layer. 
     
     
         8 . The compressive bump cap of  claim 1 , wherein the inner protection system is removably positioned in the pocket defined by the inner stretchable fabric layer and the outer stretchable fabric layer. 
     
     
         9 . The compressive bump cap of  claim 1 , wherein the inner stretchable fabric layer is stitched to the outer stretchable fabric layer to define the pocket. 
     
     
         10 . The compressive bump cap of  claim 1 , further comprising an elastic member positioned proximate to and encircling the circular opening. 
     
     
         11 . The compressive bump cap of  claim 1 , wherein at least a portion of the inner stretchable fabric layer is mesh. 
     
     
         12 . The compressive bump cap of  claim 1 , wherein at least a portion of the outer stretchable fabric layer is mesh. 
     
     
         13 . The compressive bump cap of  claim 1 , wherein each of the inner stretchable fabric layer and the outer stretchable fabric layer comprise a plurality of individual panels. 
     
     
         14 . A compressive bump cap, comprising:
 a multi-layer sidewall, wherein the multi-layer sidewall forms a dome, wherein the dome defines a circular opening for a head of a wearer, and wherein the multi-layered sidewall comprises:
 an inner stretchable fabric layer; 
 an outer stretchable fabric layer, wherein the outer stretchable fabric layer and the inner stretchable fabric layer collectively define a pocket, and wherein the inner stretchable fabric layer and the outer stretchable fabric layer are expandable from a relaxed state to an expanded state; 
 a rigid layer positioned with the pocket; and 
 a padding layer positioned within the pocket between the rigid layer and the inner stretchable fabric layer. 
   
     
     
         15 . The compressive bump cap of  claim 14 , wherein the rigid layer is coupled to the padding layer. 
     
     
         16 . The compressive bump cap of  claim 15 , wherein the rigid layer and the padding layer are removable from the pocket. 
     
     
         17 . A compressive bump cap, comprising:
 a multi-layer sidewall, wherein the multi-layer sidewall forms a dome, wherein the dome defines a circular opening for a head of a wearer, and wherein the multi-layered sidewalls comprises:
 an inner stretchable fabric layer; 
 an outer stretchable fabric layer; and 
 an inner protection system removably non-removably positioned in a pocket defined by the inner stretchable fabric layer and the outer stretchable fabric layer, wherein the inner protection system comprises a rigid layer coupled to a padding layer; and 
   wherein the inner stretchable fabric layer and the outer stretchable fabric layer are expandable from a relaxed state to an expanded state.   
     
     
         18 . The compressive bump cap of  claim 17 , wherein the rigid layer comprises a molded shell. 
     
     
         19 . The compressive bump cap of  claim 18 , wherein the padding layer comprises pliable rate-dependent material. 
     
     
         20 . The compressive bump cap of  claim 17 , wherein each of the inner stretchable fabric layer and the outer stretchable fabric layer comprise a plurality of triangular individual panels.
