Abstract

La présente invention vise à réduire l'épaisseur et le poids d'une partie dossier en utilisant une configuration simple. Un coussin de siège (110) présente une partie coussin principal (111, 112) et une partie coussin périphérique (113), un bord arrière de la partie coussin principal (111, 112) étant disposé dans un cadre de coussin (100) de façon à être comprimé vers le haut de manière élastique par rapport à la partie coussin périphérique (113). En d'autres termes, la partie coussin principal (111, 112) sur laquelle une personne s'assoie est comprimée vers le haut de manière élastique sans un ressort métallique ou similaire. Ainsi, même si la partie coussin principal (111, 112) est fabriquée dans un matériau plus fin (uréthane, etc.) que le matériau conventionnement employé, il est possible de proposer des caractéristiques souhaitées, telles qu'une sensation de compression du siège lorsqu'on s'assoie dessus, l'absorption des vibrations, l'absorption des chocs, et similaire ; par conséquent, il est possible pour la présente invention de contribuer à réduire le poids d'une partie dossier en utilisant une configuration simple.
