リング２を受止めるようになっている。C. Prior Art For example, in an automobile seat, as shown in FIG. 3, a pad 1 made of urethane foam is used as a seat spring 2.
In order to prevent the seat spring from being damaged by the pad 1, a supporter 3 is formed on the back side of the pad 1 to form a cushion body 4, and the seat spring 2 is received by the supporter 3 of the cushion body 4. There is.

成形されるのでおる。By the way, as shown in FIG. 4, the cushion body 4 has a urethane stock solution 1 in a lower mold 12 having a bottom wall 10 and side walls 11.
3, a sheet-like supporter 3 is placed on top of the supporter 3, and the upper mold 14 is recessed to foam the urethane stock solution 13. By foaming the urethane stock solution in this molding method, the pad 1 of the cushion body 4 is formed, and the supporter 3 is molded to back this pad 1.

The upper mold 1 of the supporter 3 along the side wall 11 from the bottom wall 10 of
4 and the lower die 12, the peripheral edge 3 rises in a curved shape.
The rim part 4a of the cushion body 4 is formed by turning a around as shown by the arrow X and foaming.

It impregnates the portion 3a, and the peripheral edge 3a of the naporter 3 becomes hard. For this reason, when the molded cushion body 4 is covered with the surface material 5, the rim portion 4a of the cushion body 4 is difficult to bend inward, making it difficult to form a sheet and resulting in poor appearance.

ある。(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a notch along the outer circumferential portion of the supporter that comes into contact with the inner surface of the side wall of the lower die, so that the urethane stock solution can fill this notch. It is designed to go around through the

。Incidentally, the same parts as those in the conventional structure are given the same reference numerals and redundant explanation will be omitted. As shown in Figures 1 and 2, the cushion body 4
The outer peripheral portion of the supporter 3A, specifically the cushion body 4
A notch 15 is provided along the outer peripheral portion of the lower mold 12 that comes into contact with the inner surface of the side wall 11 during molding.

発泡する。In the cushion body 4, first, a urethane stock solution 13 is injected into a lower wall 12 having a bottom wall 10 and side walls 11. Next, a supporter 3A having a notch 15 on the outer periphery is placed on top of the lower mold 12, and the upper mold 14 is placed thereon and the pins 16 of the upper mold 14 are inserted into the local parts of the supporter 3A.
Position 3A. With this upper mold 14 covered, the outer peripheral part of the beam porter 3A is in contact with the inner surface of the side wall 11 of the lower mold 12, and a shape is formed between the side wall 11 of the lower mold 12 and the outer peripheral part of the upper mold 14. Arranged in a curved manner in the space. Next, the urethane stock solution 13 is foamed and molded. During foaming of the urethane stock solution 13, it passes from the bottom wall 10 of the lower mold 12 along the side wall 11 through the notch 15 and around the outer peripheral portion of the supporter 3A in the direction shown by arrow Y, and foams.

るという効果がおる。(Effects of the Invention) As is clear from the above description, according to the present invention, since a notch is provided along the outer circumferential portion of the supporter that comes into contact with the inner surface of the side wall of the lower mold, the urethane stock solution is passes through the notch and goes around from the lower mold side to the upper mold side,
The degree of impregnation of the outer peripheral portion of the supporter is reduced. As a result, the peripheral edge of the supporter does not become abnormally hard and maintains appropriate elasticity, so when the cushion body is covered with the surface material, the rim part of the cushion body flexes inward to form the seat. This has the effect of improving appearance and improving appearance.
