Claims

[Scope of utility model registration request]

A lower frame fixed to the vehicle floor and an atsupa frame arranged above it on which a seat cushion is placed are connected by a parallel link, and both ends of the parallel link are fixed to each other in order to apply a spring force to the lower frame. In a seat suspension device in which a torsion bar twisted and formed at an angle is attached and the above-mentioned Atsupa frame is elastically supported by parallel links, a shaft equipped with an adjustment handle is attached to the underside of the above-mentioned Atsupa frame. This means that an eccentric pin is provided at the tip of the shaft, and this is brought into contact with one end of the torsion bar, and by rotating the shaft, the amount of torsion of the torsion bar is controlled via the eccentric pin. A seat suspension device that adjusts the elastic support force of a vehicle seat by increasing or decreasing it.
