2) and the lower mold (3), and place the spring receiving member (
18) and this spring receiving member (18).
) is made by inserting a polyvinylidene chloride film (19) on the back side and foaming the urethane resin. The skin member (5) includes a body part (7), a frame part (8), and a gusset part (9).
The frame portion (8) and the gusset portion (9) are made of a single piece of fabric, and both are sewn together via the beading (10). In addition, the end of the gusset part (9) is tied to the 7 frame (11) with a hook ring (12),
Pad (6) is not glued. And the body part (
7) is the skin (13) and the foam wadding (14)
, a laminate consisting of the king of wadding covers (15),
These are fused together by high frequency welding. The wadding (14) of the fused member is crushed and a decorative groove appears on the skin (13) above it.

An adhesive is applied to the outer skin of the pad (6) covered by the body portion (7), and the pad (6) is fixed to the pad (6) by adhesion. This pad (6) is placed on a spring plate support member (17) stretched over a frame (11).

から、座り心地は良好となる。According to the vehicle seat according to the above configuration, the pad (6) is formed by the film (19) during urethane foaming.
It is possible to prevent urethane foaming liquid or gas from impregnating the spring receiving member (18), and the film (17) is fused to the pad (6) by the foaming heat (about 300°C), and the spring receiving member ( 18) can be prevented from curing. Therefore, even if the pad (6) is placed on the spring plate support member (17), the spring receiving member (18) of the pad (6) is not hardened, so when a passenger sits on this seat, The cushioning force applied to the pad (6) is smoothly transmitted to the spring plate support member (17), and the desired deflection of the spring plate support member (17) can be obtained, resulting in good sitting comfort.
