Abstract

The suspension system comprises a gas spring 21 on which a seat is supported, the gas spring 21 being connected by an inlet valve 24 to a compressed gas source, and via an exhaust valve 26 to "exhaust". A lever (35), movable by a part of the seat suspension which moves as the seat rises or falls from a mid-ride position, operates the valves 24, 26 as appropriate to raise or lower the seat by allowing gas to enter or leave the gas spring. A small orifice 37 restricts the flow of gas to or from the spring so much that vibrations under about one second duration do not significantly raise or lower the seat. A dump valve operable when the seat reaches an up-stop position directly connects the gas spring to exhaust for a quick return to its mid-ride position.
