Protective helmet for the head

Abstract

Protective helmet for the head formed by an internal shock-absorbing body ( 3 ) and an external shell. The internal shock-absorbing body ( 3 ) has a built in interior reinforcement structure ( 5 ) made of filaments ( 6 ) formed by a fibre core and a coating made of carbon resin and nanofibres.

1 . Protective helmet for the head, comprising an internal shock-absorbing body, which has a built in interior reinforcement structure and, an external shell made of plastic material, characterised in that the interior reinforcement structure is formed by filaments, which include a core of fibres and a coating, formed by resin and carbon nanofibers, these filaments forming a net which is built into the interior of the shock-absorbing body. 
     
     
         2 . Helmet according to  claim 1 , characterised in that the carbon nanofibers come to form part of the coating layer in a ratio of between 0.1 and 5% in weight of resin. 
     
     
         3 . Helmet according to  claim 1 , characterised in that the carbon nanofibers come to form part of the coating layer in a ratio of between 0.5 and 1.5% in weight of resin. 
     
     
         4 . Helmet according to  claim 1 , characterised in that the carbon nanofibers have a graphene structure. 
     
     
         5 . Helmet according to  claim 1 , characterised in that the filaments are made of synthetic fibres. 
     
     
         6 . Helmet according to  claim 1 , characterized in that the filaments are made of natural mineral fibres.
