Abstract
A seat suspension method in one approach involves applying a dampening force over less than the full range over which a seat may be raised and lowered by a seat height adjuster. The step of applying a dampening force may comprise applying such a force which varies non-linearly, depending upon the extent a seat moves as a result of seat vibration. In several specific approaches, unlatching of the dampening mechanism may be accomplished to permit relative movement of the seat and seat support mechanism during seat height adjustment. Relatching of the vibration damper may be accomplished to again apply a dampening force. The seat may automatically be returned toward a desired elevation in the event loading on the seat is varied, for example if a seat occupant leaves the seat.
