Abstract
A seat suspension is provided that has a damper unit which is connected between the seat and the chassis on which the seat is mounted. The damper can be switched between soft and hard settings. The damper switching is controlled based on the relative position of the seat and one of the relative or absolute velocity of the seat. When the seat and the chassis are moving in the same direction the damper is set to soft, (producing a low damping effect), while when the seat and chassis are moving in opposite directions the damper is switched to hard (producing a high damping effect).
