CUSHION BODY, SITTING SEAT AND PROCESS FOR MANUFACTURING THEM

WIPO Patent Application WO/2007/114233

A1

[PROBLEMS] To provide a cushion body that presents soft tactile sensation and excels in the reproduction of groove portion configuration, and provide a sitting seat containing the cushion body and a process for manufacturing them. [MEANS FOR SOLVING PROBLEMS] Cushion body (11) is composed of multiple sheet-shaped fiber structures (4a-4e) superimposed one upon another and at its surface layer is provided with groove portion (12). The sheet-shaped fiber structures (4a-4e) each have web (2) laminated so that the direction of outward extension thereof is along the direction of thickness. The surface layer sheet-shaped fiber structure (4e) disposed as the surface layer has a thickness approximately equal to or smaller than the depth of the groove portion (12). The sheet-shaped fiber structures (4a-4e), as having web (2) laminated, sag in the direction of thickness (T) upon sitting to thereby present soft tactile sensation. As the surface layer sheet-shaped fiber structure (4e) has a thickness approximately equal to or smaller than the depth of the groove portion (12), the force to return toward the direction along the direction of thickness (T) of the web (2) expanded into the configuration of the groove portion (12) is lessened to thereby minimize dulling or slacking of the configuration of the groove portion (12).
