CUSHION BODY, SITTING SEAT AND PROCESS FOR MANUFACTURING THEM

摘要

[PROBLEMS] To provide a cushion body that realizes not only a large load supporting force but also soft tactile sensation, being capable of desirably maintaining the uneven configuration of groove portion or the like made at the surface brought into contact with the sitter, and provide a sitting seat containing the cushion body and a process for manufacturing them. [MEANS FOR SOLVING PROBLEMS] There is provided cushion body (11) formed from fiber structure (4) composed of a mixture of main fiber and binder fiber by the use of shaping mold (40) with cavity of given configuration (40a), wherein the fiber structure (4) consists of web (2) being a mixture of main fiber and binder fiber laminated so that the direction of outward extension of the web (2) is along the direction of thickness of the fiber structure (4), and wherein the fiber structure (4) is arranged so that the direction of thickness thereof is along the direction of thickness of the cushion body (11). Further, the cushion body (11) is provided with groove portion (12) of given width depressed in the direction of thickness of the fiber structure (4). The groove portion (12) is formed so that the direction of width thereof (Wd) is orthogonal to the direction of lamination (L) of the web (2) constituting the fiber structure (4).
