That is, the seat cushion A and the seat back B embodying the present invention are as follows:
It is equipped with a seat cushion frame 3A and a seat back frame 13A, which serve as a base for assembly, and the upper and front parts of these frames 3A and 13A are covered with cushioning materials IA and IIA, such as foamed urethane pads, and
Trim covers 2A and 12A are attached to the cushioning materials IA and IIA, which are partially adhered to the cushioning materials IA and 11A to form an integral skin shape, while wrapping the same cushioning materials IA and IIA. Specifically, the center part 2a and front part 12a of these trim covers 2A, 12A are the same as the conventional ones in that a plurality of places are bonded to the upper surface of the cushioning material IA, IIA. According to the present invention, the cushion material I
Concave grooves 4, 4A are formed on the left and right side surfaces of A, IIA, and both sides 2b of trim cover 2A, 12A,
The same concave groove 4 is formed by using a part of 12b as folded parts 2c and 12c.
, 4A. Therefore, as shown in FIG.
By forming the seat cushion A slightly closer to the front than the middle part in the thickness direction, the upper part of the seat cushion A and the front part of the seat back B can be given a cushion-like shape. In other words, according to the present invention, it is possible to give the integrally molded sheet a luxurious appearance as if it were a sheet having a double-layered cushioning material.

In the illustrated example, the cushion material IA.

Trim cover 2A covers the entire outer surface of 11A.

12A, when integrally press-molded with the cushioning materials IA and IIA, the portions from the center portion 2a and front portion 12a to the folded portions 2c and 12c are formed into the cushioning material IA and IIA.
A, Points are glued to 11A. Therefore, both sides 2b, 12b of the trim cover 2A, 12A
is cushion material LA.

Although not bonded to the left and right side surfaces of the seat cushion frame 3A and the seat back frame 13A, as shown in FIGS.
, IIA.

FIGS. 3 and 4 show the upper end processing structure of the seat back B, and the extension part lid connected to the surface side end of the cushioning material 11A is larger than the general part of the cushioning material IIA with the concave groove 4A as a border. The surface side extension li is molded to be sufficiently long.
The extension part 12d formed at the upper end of the trim cover 12A corresponding to d is formed into a "U"-shaped cross section in order to surround a part of the front and both side surfaces of the front side extension part lid, and is attached to the cushion material 11A. Glued. The folded part 12c described above is cut off from the part 12g where it is divided into the folded piece 12e of the extension part 12d and the shoulder cover part 12f that covers the shoulder part 11g of the general part upper surface 11f of the cushioning material 11A.
