ABSTRACT:
A seat is mounted on an L-shaped trolley frame which moves vertically along two spaced rails of a seat support frame. An airspring cushion member is fixedly mounted adjacent the seat support frame and has one end interconnected with the movable trolley to cushion the downward movement of the seat. The airspring cushion has a charging valve for pressurizing the airbag and a manually operable air bleeding device for selectively relieving air pressure from the cushion to permit an occupant of the seat to select an appropriate pressure and cushioning effect. After the proper cushioning rate has been obtained, a manually adjustable height adjustment device may be used to move the seat vertically into a comfortable operating position.
