Abstract: The present invention solves the problem of realizing a lighter cushion body that has ample cushioning properties when a person sits or lies thereon by: providing a plurality of rod-shaped or flat plate-shaped support bodies (2) comprising a synthetic resin foam that has a bending deflection amount of 20 mm or more as measured according to the method described in JIS K7221-2:2006 and a pressing force of 2-100 N at 20 mm of deflection, and legs (3) on which the support bodies (2) are placed or fixed; using the support bodies and the legs to form a space (5) that makes it possible to bend and deform the support bodies; and arranging the plurality of rod-shaped or flat plate-shaped support bodies (2) in a row so as to be deformable.

Abstract: A seat back for vehicles including a seat back pad having supporting bodies fixed on a periphery of an opening or a seat frame, or formed integrally with the periphery of the opening by one or multiple-point support, the supporting bodies aligned at predetermined intervals, each arranged in a direction between periphery portions opposite to each other of the opening at a front surface portion formed as a backrest surface for a seated person, the supporting bodies being independent of each other in rod or plate form, each made of a synthetic resin foam having 20 mm or larger in bending deflection amount and 2 to 100 N in load when deflected by 20 mm measured in accordance with a method defined by JIS K7221-2:2006, and having an interspace portion configured such that the supporting bodies are allowed to be deformed by bending in a rear direction.

Abstract: A long synthetic resin foam body composed of a thermoplastic resin expanded beads-molded substrate and a frame having displacement regulating sections provided at both ends in the longitudinal or lateral direction of the substrate and a connecting section that connects the displacement regulating sections to each other. The substrate has at least one joint forming portion that divides the substrate in a direction intersecting the connecting section into two or more substrate parts. The joint forming portion has a joint that connects the adjacent two substrate parts to each other and is deformable to permit a relative displacement between the adjacent two substrate parts when the substrate contracts or expands.
