ABSTRACT:
A fore-and-aft suspension device for an automotive seat, in which the seat lower base frame of said seat is movable forwardly and backwardly along a guide rail, and a shaft extends between the seat lower base frame and guide rail, with a pair of coil springs being wound around the shaft. A spring abutment member is also provided between the seat lower base frame and guide rail, such that those coil springs are at their respective ends abutted against both sides of the spring abutment member. Thus, a forward and backward load or jolting applied to the seat is smoothly transmitted, via such seat lower base frame, to the the coil springs, which are then compressed at the spring abutment member, absorbing the forward and backward load or jolting.
