CA 2191678

The invention relates to a protective helmet chaving a rigid outer shell and an inner pad assembly comprising a front pad assembly, a rear pad assembly and an intermediate pad assembly. Each of the front, intermediate and rear pad assemblies is made from a generally rigid shock absorbing material and comprises a second generally soft inner liner secured to the generally rigid shock absorbing material. By varying the density or the thickness of the generally rigid shock absorbing material at specific areas, the helmet may be customized to meet the required certification norms while being very light and close fitting. The helmet of the invention also comprises improved ventilation features that result from the provision of recessed channels in the first generally rigid liner.

La présente invention a trait à un casque protecteur comportant une calotte externe rigide et un ensemble de coussinets intérieurs, soit un avant, un arrière et un intermédiaire. Chaque coussinet est constitué d'un matériau amortisseur de chocs généralement rigide et comporte une deuxième épaisseur interne généralement souple fixée au matériau amortisseur de chocs généralement rigide. En variant la densité ou l'épaisseur du matériau amortisseur de chocs généralement rigide à des endroits précis, le casque peut être adapté pour satisfaire aux normes d'homologation établies tout en étant très léger et bien ajusté. Le casque faisant l'objet de l'invention comporte aussi des orifices d'aération constitués de canaux réalisés dans la première épaisseur généralement rigide.
