Safety Helmet

Abstract

The present invention provides a protective helmet to protect the wearer from a brain injury when engaged in a contact sport. The helmet comprises an outer shell formed as a sandwich comprising outer and inner impact resistant non-fracturing layer which encases an intermediate layer made of a resilient gel layer, carbon fiber layer and disjoined stack member layer. The inner wall of the inner impact resistant layer further comprises a plurality of disjoined gel patches attached thereon.

         4 . The helmet of  claim 1  wherein the inner layer further comprises an inner surface with a plurality of disjoined resilient gel patches attached thereto. 
     
     
         5 . The helmet of  claim 1  wherein the outer and inner impact resistant layer is lightweight and approximately five times stronger than steel. 
     
     
         6 . The helmet of  claim 1  wherein the outer and inner impact resistant layer is made of an aramide composite material. 
     
     
         7 . The helmet of  claim 1  wherein each stack member of the plurality of stack members further comprise a plurality of layers with varying densities of a carbon superimposed upon a closed-cell extruded polystyrene foam. 
     
     
         8 . The helmet of  claim 1  wherein the shock absorbing resilient material is an absorbent gel layer. 
     
     
         9 . The helmet of  claim 1  wherein the carbon fiber like layer is graphite fiber. 
     
     
         10 . The helmet of  claim 1  wherein the carbon fiber like layer is a composite material. 
     
     
         11 . The helmet of  claim 1  wherein the carbon fiber like layer is reinforced with a polymer, plastic material, or thermoplastic material. 
     
     
         12 . The helmet of  claim 1  wherein the carbon fiber like layer is bonded with aramid, glass, or glass fibers. 
     
     
         13 . The helmet of  claim 1  wherein the stack composite member have substantially a triangular shape. 
     
     
         14 . The helmet of  claim 1  wherein the stack layer has a thickness of at least 14 mm. 
     
     
         15 . The helmet of  claim 1  wherein the shock absorbing resilient material has a thickness of at least 6.5 mm. 
     
     
         16 . The helmet of  claim 1  wherein the outer layer flexes inward upon impact. 
     
     
         17 . A protective helmet comprising an outer shell formed of multiple layers for the helmet having a spheroid shape with a base opening configured to receive a wearer's head, the outer shell comprising:
