ABSTRACT:
The device comprises a stationary bottom frame, a vertically movable top frame urged upwards by a compression spring, and scissors-type guiding levers between the top and bottom frames. One end of the spring is applied against the guiding levers and the other end is applied against a screw-and-nut system for adjusting flexibility of the suspension according to the weight of the user. A screw or a toothed rack are provided for adjusting the useful vertical range of travel of the suspension according to the height of the user.
