Abstract

The suspended seat (1) for wheeled or tracked vehicles has top and bottom cradle guides (90, 91) taking two parallel articulated connecting rods (93) and guiding the top of the main connecting rod (92). The bottom end of this rod (94) is convex (102) and is screwed to the hydraulic jack (95) through the armed membrane (98). Vertical movement of the seat is resisted by the plunger in the chamber and by the movement of the chamber on the flexible membrane (99) resting on the pneumatic chamber (101). Fluid is allowed in and out of the hydraulic chamber by the lever (96) working the distributor (94).
