ABSTRACT:
A weight adjustment support device for a vehicle seat such as an automotive seat is disclosed which is capable of adjusting the cushioning property of the seat according to weights or taste of an occupant. The device includes a mounting frame and a seat supporting frame on which the seat is placed. A pair of X-shaped expansion legs are provided between the two frames to be able to raise or fall the seat supporting frame vertically. A pair of wedge members are provided to secure one end of the expansion leg via elastic means. The two wedge members are combined such that the slanting surface of one wedge member having a grade is applied against the slanting surface of the other wedge member having the same but oppositely directed grade. The one wedge member is then moved by means of a feed mechanism to vary the distance between the respective bottom surfaces of the two wedge members so as to be able to adjust the energizing forces of the elastic means.
