In a seat bag on which a pad p is hung and further covered with a skin h, an S-shaped spring s is connected to a frame f and a support frame f1 via mounting brackets k1 and k2, and the skin h is connected to the S-shaped spring s. Because the seat was fixed with a wound bog ring r, it not only made the seat structure more complicated, but also had the drawback of producing unpleasant noises due to sliding contact between metal parts as the S-shaped spring s expanded and contracted when the occupant was seated. It was hot.

サートされる。 Reference numerals 3 to 3 designate an appropriate number of rows of springs buried in parallel in the pad 1 at distances apart in the longitudinal direction, each of which is curved into a substantially wave shape, and both ends 3a of the springs 3 are parallel to each other. In order to stretch the pad 1 over both vertical frames of the frame 2, the pad 1 is bent into a hook shape along both side edges of the pad 1, and a spring 3 provided opposite to the groove 1a in the pad 1 is a spring 3. The lower folded end 3b of the projection 1b
It is positioned and buried so that it is opposite to the
Incidentally, each spring 3 is set and inserted into the pad 1 during molding of the pad 1 so that the springs 3 are spaced apart from each other and lined up in a mold for molding the pad 1.

The pad 1 and the reinforcing sheet 4 are passed through the groove 1a and wound around the folded end 3b of the spring 3 so that contact with the folded end 3b is restricted. A part of 5 can be locked to the spring 3.
次に、上記した構成をもつ実施例の作用と効果

して固定されるように被覆してある。 Now, in this example, a reinforcing sheet 4 for reinforcing the pad 1 is attached to the back side of the pad 1, which is molded to be elastically compressible and capable of being hung on the frame 2. Embedded are substantially wave-shaped springs 3 whose both ends are bent along the edges of the pad 1 and are arranged at a distance from each other in the longitudinal direction of the pad 1 in order to be stretched over the frame 2 via the reinforcing sheet 4. Further, a skin 5 is attached to the seat shell K, and a part of the skin 5 penetrates a part of the spring 3 through the pad 1 and the reinforcing sheet 4 and is wound around the spring 3. It is coated so as to be fixed via the turned coupling fitting 6.

音の発生を防止することができる。 Therefore, when the occupant is seated, the pad 1 and the spring 3 act as one unit to improve the cushioning effect of the seat shell K and the durability of the pad 1. 2
and the coupling fitting 6 is wound around the spring 3 via the pad 1 and reinforcing sheet 4,
Even when the spring 3 expands and contracts, it is possible to prevent abnormal noise from occurring due to sliding contact between metals.

用的に優れた考案である。 That is, in the present invention, a reinforcing sheet for reinforcing this pad is attached to the back side of a pad that is molded to be elastically compressible and can be hung on a seat frame, and the same pad and the above-mentioned pad are attached inside the pad. A suitable number of rows of springs curved into a substantially wavy shape are arranged in order to be stretched on the frame via a reinforcing sheet, and both ends of each spring are bent substantially along the edge of the pad, and the springs are bent along the edge of the pad. By embedding the sheets in parallel and spaced apart from each other to form a seat shell and covering the seat shell with a skin, the seat structure can be simplified and the assembly of the seat can be simplified. This is an extremely practical idea for the structure of vehicle seats because it can prevent metal sliding noise from occurring.
