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.

L'invention concerne une structure de rembourrage sans couches impregnée de mousse pour un siège de véhicule, dans laquelle une matière de surface est fixée à une matière de rembourrage à l'aide d'une matière de collage à plat. Dans la structure de rembourrage sont formés des espaces ouverts (10) entre des bords latéraux d'une matière (4) de collage à plat et des parties latérales (3) d'une matière de rembourrage (2, 3), ainsi que des parties (7) non impregnées situées au niveau des bords latéraux cités, par moulage unitaire de la matière (4) de collage à plat et de la matière (2, 3) de rembourrage, ladite matière (4) de collage à plat étant maintenue et positionnée de manière isolée par des parois (22, 23) empêchant l'entrée de liquide expansible à l'état brut, dans un moule (2) destiné à la matière (2, 3) de rembourrage.
