Improved helmet protection, composite structure, designed more specifically to vehicle users - two-wheelers.

摘要

Helmet improved protection of composite structure, intended more specifically to users of two-wheeled vehicles, characterized in that the outer part is made by coupling a rigid upper cap, obtained by injection of polycarbonate or ABS, molding polyester laminates, integral with a lower semi-rigid shell of plastic, the plasticized PVC type or thermoplastic polyurethane injected carrying extensions level ears, the coupling being secured by gluing and / or riveting or stapling, state the inside which dampens shocks also consists of two elements, comprising a rigid upper shock, for example expanded polystyrene, volumetric mass of between 15 and 20 g / dm3 or semi-rigid polyurethane expanded volumetric mass of between 30 and 120 g / dm3, hemispherical, and a lower ring shaped cushion Semi-rigid foam polyurethane, for example.
