Abstract

La présente invention vise à renforcer l'efficacité de fabrication et à réduire les coûts en permettant à une doublure d'être disposée très simplement et de manière sûre sur l'intérieur d'une coque sans utiliser d'adhésif ou similaire. À cet effet, un casque selon l'invention comprend : une coque (2) qui recouvre la tête d'un porteur et qui forme la forme extérieure d'un casque ; et une doublure d'amortissement (3) disposée entre la tête de l'utilisateur et l'intérieur de la coque (2). La doublure (3) est conçue sous la forme d'une doublure par combinaison d'une pluralité de pièces de doublure (3a, 3b, 3c) dans le sens avant-arrière ou dans le sens gauche-droite de la coque (2) ; et une ouverture d'enfilage (5), qui est destinée au porteur et ménagée dans la coque (2), est formée en tant que section de bord de contraction (10) ayant une ouverture réduite de façon à empêcher qu'une extrémité de liaison de pièces (11) ne s'échappe lors de la combinaison des pièces de doublure (3a, 3b, 3c) dans la coque (2).
