ABSTRACT:
A body-weight adjusting device for a seat suspension is provided including a combination of bell cranks, tension springs and a connecting rod. Vertical movement of an operation lever results in an increase or decrease in the tension of the springs (depending upon the starting position of the lever) in response to which the seat suspension mechanism is raised or lowered correspondingly so as to permit a selective adjustment of the seat suspension in accordance with the weight of a seated occupant.
