A CUSHION BODY STRUCTURE COMFORTABLE TO SIT

摘要

In a cushion body structure of a car seat, which is made of fastening a skin material to a cushion material by using a planed fastening material, an impregnation layer made of a foamed body is not produced. In the cushion body structure, a planed fastening body (4) is integrally molded with a cushion material by shealding and clamping by walls (22, 23) for preventing an entry of a foaming solution in a molding die (20) of the cushion material (2,3), so that an opening space is provided between the periphery of the planed fastening body and the side (3) of the cushion material and a non-impregnation layer is formed in the periphery.
