(FR) CASQUE
Abstract
(EN)
A helmet comprises a protective shell, a first energy absorbing layer, a second energy absorbing layer and multiple displace devices. The protective shell forms an outer surface of the helmet. The first energy absorbing layer has a first outer surface and a first inner surface. The first inner surface is configured to couple the helmet to a wearer's head. The second energy absorbing layer has a second outer surface and a second inner surface. The second inner surface faces the first outer surface. The multiple displacement devices are positioned at multiple locations between the first energy absorbing layer and the second energy absorbing layer. The displacement devices allow displacement between the first and second energy absorbing layers in response to an oblique impact to the helmet.

La présente invention concerne un casque comprenant une coque de protection, une première couche d'absorption d'énergie, une seconde couche d'absorption d'énergie et de multiples dispositifs de déplacement. La coque de protection forme une surface extérieure du casque. La première couche d'absorption d'énergie a une première surface externe et une première surface interne. La première surface interne est configurée pour coupler le casque à la tête d'un utilisateur. La seconde couche d'absorption d'énergie a une seconde surface interne et une seconde surface externe. La seconde surface externe est opposée à la première surface externe. Les multiples dispositifs de déplacement sont positionnés à de multiples emplacements entre la première couche d'absorption d'énergie et la seconde couche d'absorption d'énergie. Les dispositifs de déplacement permettent un déplacement entre les première et seconde couches d'absorption d'énergie en réponse à un impact oblique sur le casque.
