支持されている。 2. Description of the Related Art Automotive seats are provided with cushion bodies having side portions that protrude beyond a main portion in order to reliably support a seated person by preventing the seating position from shifting due to the rocking of the vehicle body. Conventionally, this type of cushion body includes a pad integrally formed from a synthetic resin foam such as urethane having the main portion and side portions, and a spring structure embedded within the pad. This spring structure has an upper frame line and a lower frame line that extend along the front and back sides of the side part (the upper and lower faces for the seat part, and the front and rear faces for the backrest part), and the middle part. is disposed in the main part, and has a plurality of spring wires whose ends extend around the lower frame line one or more times and are wound and locked around the upper frame body. Both ends of the cushion body are supported by the seat frame via tension coil springs that are relatively movably hooked onto the seat frame and the lower frame line, respectively.

ーされたばね鋼線から形成されている。 Hereinafter, the present invention will be described with reference to an illustrated embodiment. In the drawings, a spring structure 1 is integrally embedded in a pad (not shown) during foam molding, and is connected to an upper frame line 2 and a lower frame line 3 extending along the front and back sides of the pad, and the middle A spring wire 4 is arranged in the main part of the pad, and extends by winding the lower frame line 3 one or more times, and has both end parts locked to the upper frame line. The upper frame line 2 and the lower frame line 3 allow relative rotation of the core wires 5 and 6 made of hard steel wire, for example, and the spring wire 4 wound around their outer peripheries, and also allow the shaft wires to rotate relative to each other. Paper cords 7 and 8 are provided for suppressing directional displacement and generation of fricative noise. Further, the spring wire 4 is formed of, for example, an oil-tempered spring steel wire.

もよい。 The spring structure 1 configured as described above is attached to the seat frame 9 together with the pad in which it is embedded.
is supported via a plurality of tension coil springs 10. That is, the tension coil spring 10 has a dogleg-shaped portion 11 formed at one end, and the dogleg-shaped portion 11 is hooked on the circumferential surface of the lower frame line 3 facing away from the seat frame 9. The tip portion 13, which is connected integrally via the square-shaped portion 11 and the raised portion 12 and is parallel to the upper frame line 2, is connected to the clip 14.
It is locked to the upper frame line 2 by. A bent portion 15 is formed on the tip portion 13 to prevent the tip from escaping from the clip 14. The tension coil spring 10 also includes a U-shaped portion 16 formed at the other end, and this U-shaped portion 16 is inserted into and hooked into a through hole 17 formed in the seat frame 9.
Note that one end of the tension coil spring 10 may be wound around the lower frame line 3 instead of the doglegged portion 11 described above.

大幅に向上することができる。 In the device configured as described above, one end of the tension coil spring 10 is locked to the upper frame line 2 through the periphery of the lower frame line 3 facing away from the seat frame 9, so that the side part of the pad Top border line 2 through
The lateral load applied to is received by the spring wire 4 and the tension coil spring 10. Therefore, the supporting force can be reinforced more than in the conventional device in which the support force is received only by the spring wire 4, and even though the spring structure 1 is elastically supported by the tension coil spring 10, Therefore, the support performance can be greatly improved.

ばね装置を提供することができる。 As described above, the present invention hooks one end of the tension coil spring stretched between the seat frame and the lower frame line to the circumferential surface of the lower frame line facing away from the seat frame, and Since the extension tip is locked to the upper frame line, the supporting performance of the side part is greatly improved compared to the conventional device in which one end of the tension coil spring is simply locked to the lower frame line. Therefore, it is possible to provide a seat spring device particularly suitable for use in automobiles.
