Helmet

Abstract

A helmet having an outer shell and an inner shell placed within the outer shell. The inner shell attached to the outer shell by a plurality of elastomeric elements to isolate the inner shell from impacts and rotational forces applied to the outer shell.

1 . A helmet comprising:
 an outer shell;   an inner shell located within the outer shell; and   a plurality of elastomeric elements attaching the inner shell to the outer shell.   
     
     
         2 . The helmet of  claim 1  wherein:
 the outer shell has a plurality of bore holes; 
 the inner shell has a plurality of bore holes arranged such that when the inner shell is located within the outer shell the plurality of bore holes in the inner shell align with the plurality of bore holes in the outer shell; and 
 the plurality of elastomeric elements is placed within the plurality of bore holes in the outer shell and the plurality of bore holes in the inner shell. 
 
     
     
         3 . The helmet of  claim 2  wherein:
 each of the plurality of elastomeric bore holes has a recess; and 
 each of the plurality of elastomeric elements has a shank sized to fit within the borehole and a head sized to fit within the recess. 
 
     
     
         4 . The helmet of  claim 2  wherein:
 the plurality of elastomeric elements have placement strands. 
 
     
     
         5 . The helmet of  claim 1  wherein:
 a chinstrap is secured to the inner shell; and 
 a facemask is secured to the outer shell. 
 
     
     
         6 . The helmet of  claim 1  wherein:
 a plurality of pads is secured to the inner shell. 
 
     
     
         7 . The helmet of  claim 1  wherein:
 a visor is secured to the outer shell. 
 
     
     
         8 . A helmet comprising:
 an outer shell having a plurality of bore holes;   an inner shell located within the outer shell and having a plurality of bore holes arranged such that when the inner shell is located within the outer shell the plurality of bore holes in the inner shell align with the plurality of bore holes in the outer shell; and   a plurality of elastomeric elements placed within the plurality of bore holes in the outer shell and the plurality of bore holes in the inner shell to form an elastic connection between the outer shell and the inner shell.   
     
     
         9 . The helmet of  claim 8  wherein:
 each of the plurality of elastomeric bore holes has a recess; and 
 each of the plurality of elastomeric elements has a shank sized to fit within the borehole and a head sized to fit within the recess. 
 
     
     
         10 . The helmet of  claim 8  wherein:
 a chinstrap is secured to the inner shell. 
 
     
     
         11 . The helmet of  claim 8  wherein:
 a plurality of pads is secured to the inner shell. 
 
     
     
         12 . The helmet of  claim 8  wherein:
 a facemask is secured to the outer shell. 
 
     
     
         13 . The helmet of  claim 8  wherein:
 a visor is secured to the outer shell. 
 
     
     
         14 . A helmet comprising:
 an outer shell;   an inner shell located within the outer shell; and   a plurality of elastomeric elements forming an elastic connection between the outer shell and the inner shell.   
     
     
         15 . The helmet of  claim 14  wherein:
 the outer shell has a plurality of bore holes; 
 the inner shell has a plurality of bore holes arranged such that when the inner shell is located within the outer shell the plurality of bore holes in the inner shell align with the plurality of bore holes in the outer shell; and 
 the plurality of elastomeric elements is placed within the plurality of bore holes in the outer shell and the plurality of bore holes in the inner shell. 
 
     
     
         16 . The helmet of  claim 15  wherein:
 each of the plurality of elastomeric bore holes has a recess; and 
 each of the plurality of elastomeric elements has a shank sized to fit within the borehole and a head sized to fit within the recess. 
 
     
     
         17 . The helmet of  claim 14  wherein:
 a chinstrap is secured to the inner shell. 
 
     
     
         18 . The helmet of  claim 14  wherein:
 a plurality of pads is secured to the inner shell. 
 
     
     
         19 . The helmet of  claim 14  wherein:
 a facemask is secured to the outer shell. 
 
     
     
         20 . The helmet of  claim 14  wherein:
 a visor is secured to the outer shell.
