Helmet

Abstract

A helmet includes a shock absorbing liner fitted on an inner side of a shell, and a layer of an elastic body for absorbing shock having a component directed along an outer surface of the shell provided between the shell and the shock absorbing liner or between an outer layer of the shock absorbing liner and an inner layer of the shock absorbing liner.

What is claimed is:  
     
         1 . A helmet having a shock absorbing liner fitted on an inner side of a shell, wherein an elastic body is provided between said shell and said shock absorbing liner for absorbing shock having a component directed along an outer surface of said shell.  
     
     
         2 . A helmet having a shock absorbing liner fitted on an inner side of a shell, wherein said shock absorbing liner is split into an outer liner and an inner liner, and a layer of elastic body is provided between said outer liner and said inner liner for absorbing shock having a component directed along an outer surface of said shell.  
     
     
         3 . A helmet as claimed in    claim 1   , wherein said elastic body is a gel.  
     
     
         4 . A helmet as claimed in    claim 2   , wherein split surfaces of said outer liner and said inner liner are formed in spherical surfaces.  
     
     
         5 . A helmet as claimed in    claim 2   , wherein said elastic body is a gel.  
     
     
         6 . A helmet as claimed in    claim 2   , wherein said inner and outer liners are movable relative to each other, and the helmet further includes a stopper which limits movement of the inner and outer liners relative to each other.  
     
     
         7 . A helmet as claimed in    claim 2   , wherein one of said inner and outer liners includes a severable projection, and the other of said inner and outer liners includes a recess mating with said projection to initially prevent movement of said inner and outer liners prior to a shock being applied to the helmet, said inner and outer liners being movable relative to each other after said projection is severed.  
     
     
         8 . A helmet as claimed in    claim 1   , wherein said elastic body is provided as a layer separating said shell and said shock absorbing liner.  
     
     
         9 . A helmet as claimed in    claim 1   , wherein said elastic body comprises a gel having air pockets disposed therewith.  
     
     
         10 . A helmet as claimed in    claim 2   , wherein said helmet includes a plurality of elastic bodies disposed in spaced relation to each other.  
     
     
         11 . A helmet as claimed in    claim 2   , wherein said elastic body comprises a gel having air pockets disposed therewith  
     
     
         12 . A helmet as claimed in    claim 1   , wherein said elastic body permits said shell to move relative to a head of a person wearing the helmet when the shock is applied to said helmet.  
     
     
         13 . A helmet as claimed in    claim 2   , wherein said elastic body permits said shell to move relative to a head of a person wearing the helmet when the shock is applied to said helmet.  
     
     
         14 . A helmet comprising a shell, shock absorbing liner fitted within said shell, and an elastic body provided in engagement with said shock absorbing liner for absorbing shock having a component directed along an outer surface of said shell.  
     
     
         15 . A helmet as claimed in    claim 14   , wherein said elastic body permits said shell to move relative to a head of a person wearing the helmet when the shock is applied to said helmet.  
     
     
         16 . A helmet as claimed in    claim 14   , wherein said elastic body is provided between said shell and said shock absorbing liner.  
     
     
         17 . A helmet as claimed in    claim 14   , wherein said shock absorbing liner is split into an outer liner and an inner liner, and said elastic body is provided between said outer liner and said inner liner such that said outer and inner liners are movable relative to each other.  
     
     
         18 . A helmet as claimed in    claim 14   , wherein said elastic body is a gel.  
     
     
         19 . A helmet as claimed in    claim 17   , wherein split surfaces of said outer liner and said inner liner are formed in spherical surfaces.  
     
     
         20 . A helmet as claimed in    claim 17   , wherein the helmet further includes a stopper which limits movement of the inner and outer liners relative to each other.
