Protective equipment

Abstract

Protective equipment comprising: a shock-absorbing liner, the shock absorbing liner comprising one or more cavities; and a fitting liner for mounting the equipment to a wearer, said fitting liner arranged between the wearer and the shock-absorbing liner and configured to move relative to the shock-absorbing liner during an impact; an attachment means attaching the fitting liner to the rest of the helmet, the attachment means being attached to the rest of the helmet within one of the cavities of the shock absorbing liner.

I/we claim: 
     
         1 . Protective equipment comprising:
 a shock-absorbing liner, the shock absorbing liner comprising one or more cavities; and   a fitting liner for mounting the equipment to a wearer, said fitting liner arranged between the wearer and the shock-absorbing liner and configured to move relative to the shock-absorbing liner during an impact;   an attachment means attaching the fitting liner to the rest of the helmet, the attachment means being attached to the rest of the helmet within one of the cavities of the shock absorbing liner.   
     
     
         2 . The protective equipment of  claim 1 , wherein the attachment means is attached to a lateral surface of the cavity that does not face the wearer. 
     
     
         3 . The protective equipment of  claim 1 , wherein the attachment means is attached to a bottom surface of the cavity that faces the wearer. 
     
     
         4 . The protective equipment of  claim 1 , wherein the attachment means is attached directly to the shock-absorbing liner within the cavity. 
     
     
         5 . The protective equipment of  claim 1 , further comprising an inner casing, said inner casing covering an external surface of the shock-absorbing liner facing the wearer. 
     
     
         6 . The protective equipment of  claim 5 , wherein the inner casing reduces the friction between the fitting liner of the helmet and the shock-absorbing liner. 
     
     
         7 . The protective equipment of  claim 5 , wherein the inner casing additionally covers at least a portion an internal surface of the shock-absorbing layer within the one or more cavities. 
     
     
         8 . The protective equipment of  claim 7 , wherein the attachment means is attached directly to the inner casing within the cavity. 
     
     
         9 . The protective equipment of  claim 8 , wherein the attachment means is connected to a lateral surface of the inner casing that does not face the wearer. 
     
     
         10 . The protective equipment of  claim 8 , wherein the attachment means is attached to a bottom surface of the inner casing facing the wearer. 
     
     
         11 . The protective equipment of  claim 5 , wherein the attachment means is attached to the fitting liner through an opening of the inner casing. 
     
     
         12 . The protective equipment of  claim 1 , wherein the one or more cavities form vents in the protective equipment for providing ventilation. 
     
     
         13 . The protective equipment of  claim 1 , wherein the attachment means is a hook-and-loop fastener, pin or rivet. 
     
     
         14 . The protective equipment of  claim 1 , further comprising an outer shell, lined by the shock-absorbing liner. 
     
     
         15 . The protective equipment of  claim 1 , wherein the protective equipment is a helmet. 
     
     
         16 . Protective equipment comprising:
 a shock-absorbing liner, the shock-absorbing liner comprising one or more cavities;   an inner casing, said inner casing attached to and covering an external surface of the shock-absorbing liner facing the wearer, and wherein the inner casing conceals the one or more cavities.   
     
     
         17 . The protective equipment of  claim 16 , wherein a contact area between the external surface of the shock-absorbing liner facing the wearer and the inner casing is smaller than the surface area of the inner casing facing the shock-absorbing liner. 
     
     
         18 . The protective equipment of  claim 16 , wherein the wherein the inner casing additionally covers at least a portion an internal surface of the shock-absorbing layer within the one or more cavities. 
     
     
         19 . The protective equipment of  claim 18 , wherein the shock absorbing liner comprises one or more of a micro-cavity structure, a macro-cavity structure, open-cavities, closed-cavities, channels, a thin walled structure, a truss structure, an auxetic structure, an uneven or jagged surface, a foam structure, collapsible structures, honeycomb structures, gas-filled compartments. 
     
     
         20 . The protective equipment of  claim 16 , wherein the protective equipment is a helmet.
