Helmets including spray on materials

Abstract

Various embodiments of helmets and methods of their manufacture are disclosed. In some embodiments, the helmet includes a helmet shell having a helmet shell edge and/or a mounting location for mounting an accessory to the helmet shell. A material that is adherent to the helmet shell may be sprayed onto the helmet shell edge of the helmet shell to form a trim. Alternatively, the material may be sprayed onto a portion of the helmet shell associated with either a mounting location for mounting an accessory or a position for a mounted accessory.

What is claimed is: 
     
         1 . A helmet comprising:
 a helmet shell including a helmet shell edge; and   a sprayed on trim directly adhered to the helmet shell and covering the helmet shell edge.   
     
     
         2 . The helmet of  claim 1 , wherein the trim covers an entire length of the helmet shell edge. 
     
     
         3 . The helmet of  claim 1  wherein the helmet shell is formed with an exterior surface and with an interior surface and the sprayed on trim directly adheres to a portion of the exterior surface. 
     
     
         4 . The helmet of  claim 1  wherein the helmet shell is formed with an exterior surface and with an interior surface and the sprayed on trim directly adheres to a portion of the interior surface. 
     
     
         5 . The helmet of  claim 1  wherein the helmet shell is formed with an exterior surface and with an interior surface and wherein the sprayed on trim directly adheres to a portion of the exterior surface and to a portion of the interior surface. 
     
     
         6 . The helmet of  claim 5  wherein a portion of the exterior surface and a portion of the interior surface is free of the sprayed on material. 
     
     
         7 . The helmet of  claim 1 , wherein the sprayed on trim comprises a polymeric material. 
     
     
         8 . The helmet of  claim 7 , wherein the polymeric material is an elastomeric material. 
     
     
         9 . The helmet of  claim 7 , wherein the polymeric material comprises at least one of polyurethane and polyurea. 
     
     
         10 . The helmet of  claim 1 , wherein the helmet shell comprises a plurality of laminated layers. 
     
     
         11 . The helmet of  claim 1 , wherein the trim substantially conforms to a shape of the helmet shell edge. 
     
     
         12 . The helmet of  claim 5 , wherein a cross-sectional shape of the sprayed on trim material includes a tapered edge. 
     
     
         13 . The helmet of  claim 1 , wherein the sprayed on trim comprises an additive or composite material to increase a fire resistance, abrasion resistance, or chemical resistance of the material. 
     
     
         14 . The helmet of  claim 1  wherein the helmet shell includes a mounting location for mounting an accessory to the helmet shell; and
 wherein the sprayed on material is directly adhered to a portion of the helmet shell associated with the mounting location. 
 
     
     
         15 . The helmet of  claim 14 , wherein the sprayed on material comprises a polymeric material. 
     
     
         16 . The helmet of  claim 15 , wherein the polymeric material comprises at least one of polyurethane and polyurea 
     
     
         17 . The helmet of  claim 15 , wherein the polymeric material is an elastomeric material. 
     
     
         18 . The helmet of  claim 14 , wherein the sprayed on material substantially conforms to a shape of the portion of the helmet shell associated with the mounting location. 
     
     
         19 . The helmet of  claim 14 , wherein the sprayed on material comprises an additive or composite material configured to increase a fire resistance, abrasion resistance, or chemical resistance of the sprayed on material.
