Abstract

Casque de sécurité offrant une excellente aération. Ce casque est constitué d'un corps présentant un espacement entre une couche interne et une couche externe. Chacune de ces couches comporte une série de trous d'aération réalisés de telle sorte que les trous de la couche interne et ceux de la couche externe se trouvent décalés les uns par rapport aux autres. De préférence, des calles d'épaisseurs sont disposées dans cet espacement. Etant donné que l'intérieur du casque, délimité par la couche interne, communique avec l'extérieur, lui même délimité par la couche externe grâce aux trous d'aération ménagés dans les deux couches et à l'espacement entre ces couches, l'air extérieur s'écoule entre l'intérieur et l'extérieur du casque. Toutefois, les trous d'aération ménagés dans l'une et l'autre couche sont disposés de manière à ne pas coïncider les uns avec les autres, de sorte qu'aucun élément en chute ou en projection ne risque de pénétrer à l'intérieur du casque.
