Abstract

A shell-less helmet is provided with resilient material and a stainless steel interior member to protect the individual from head trauma while at the same time preventing the use of the helmet as a weapon due to the resilient helmet outer layer.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A shell-less helmet for protecting an individual wearing the helmet from helmet impacts, comprising:
 an outer helmet member comprising a first layer of resilient material;   a stainless steel member interior to said outer helmet member to absorb helmet impact from the exterior of the helmet, and,   a foam layer interior to said stainless steel member to cushion impact from the outside of the helmet, said foam layer adapted to contact the individual wearing said helmet.   
     
     
         2 . The helmet of  claim 1 , and further including a fabric liner interior to said foam layer. 
     
     
         3 . The helmet of  claim 2 , wherein said fabric liner is releasably attachable to said foam layer. 
     
     
         4 . The helmet of  claim 1 , and further including a second resilient layer to the interior of said stainless steel member such that said stainless steel member is sandwiched between said resilient layers. 
     
     
         5 . The helmet of  claim 1 , and further including a gel layer positioned between said stainless steel member and said foam layer. 
     
     
         6 . The helmet of  claim 1 , wherein said stainless steel member is an austenitic nickel alloy. 
     
     
         7 . The helmet of  claim 6 , wherein said stainless steel member is 304 stainless. 
     
     
         8 . The helmet of  claim 6 , wherein said stainless steel member is 8-18 A2 stainless. 
     
     
         9 . The helmet of  claim 4 , wherein said resilient layers include silicone rubber layers. 
     
     
         10 . The helmet of  claim 1 , and further including a rear neck extension portion extending down from the base of said helmet, said neck extension portion including a sandwich of an outer layer of silicone rubber, an inner foam layer and a gel layer sandwiched therebetween. 
     
     
         11 . The helmet of  claim 1 , and further including a aperture in said helmet running through said resilient member, said stainless steel member and said foam layer providing ventilation to the interior of said helmet and providing an audio passage to the interior of said helmet. 
     
     
         12 . The helmet of  claim 11 , and further including a fan in said aperture. 
     
     
         13 . The helmet of  claim 11 , and further including an audio reproduction unit in said aperture. 
     
     
         14 . The helmet of  claim 4 , wherein said stainless steel member has a periphery and further including an expanded shaped end at said periphery. 
     
     
         15 . The helmet of  claim 14 , wherein said expanded shaped end is pear shaped and includes barbs adapted to secure the pear shaped end to adjacent resilient layers. 
     
     
         16 . The helmet of  claim 1 , wherein said foam layer include viscolastic foam. 
     
     
         17 . The helmet of  claim 16 , wherein said viscolastic foam includes NASA foam. 
     
     
         18 . A method of protecting an individual from head impact comprising the step of providing the individual with a helmet having a resilient outer member, an interior stainless steel member adjacent said outer member, a resilient inner member adjacent said stainless steel member, a gel member adjacent said inner resilient member and a foam layer adjacent said gel layer, the combination of the stainless steel member sandwiched between resilient adjacent members, the gel member and the foam layer protecting the head of the individual from head impact. 
     
     
         19 . A helmet comprising:
 a resilient outer member;   an interior stainless steel member adjacent said outer member;   a resilient inner member adjacent said stainless steel member;   a gel member adjacent said inner resilient member; and,   a foam layer adjacent said gel layer, the combination of said stainless steel member sandwiched between resilient adjacent members, the gel member and the foam layer protecting the head of the individual from head impact without providing a hard outer shell.   
     
     
         20 . Apparatus for protecting an individual from head impact comprising:
 a helmet having a resilient outer member, a resilient inner member and an interior member sandwiched between said resilient outer member and said resilient inner member, said interior member having physical characteristics associated with stainless steel, the combination of said interior member sandwiched between said resilient members providing head protection without a rigid outer shell.
