<p>A vehicle seat suspension unit has a base frame (11) and seat support frame (15) connected by a scissor arm assembly to enable relative movement of the frames (11, 15) in parallelism. A transfer assembly (50), pivotally mounted on the base frame (11), has a pair of transfer levers (54) slidably connected to the seat support frame (15), and adjustable spring assembly (40) connected to the base frame (11) and transfer assembly (50), to set the suspension unit at an initial height. A brake disc damper assembly or decelerator (centred on pin 52) provides zero damping at small displacements of the frames (11, 15), increasing damping as the displacement increases. Also disclosed is a seat slide assembly consisting of fixed and movable slides, latch means to lock their relative positions and overlapping flanges on both slides to prevent separation during an accident.</p> |
