A method for limiting endstop collisions when non-typical inputs are experienced and also when the seat is leveled at a position above or below the normal leveling zone limits. According to the method of the invention a temporary or transient control method referred to as rebound control method causes a large damping force to be applied by the seat suspension system in response to non-typically large inputs. The large damping force is applied until a duration timer timesout. Also according to the invention, a level control algorithm provides additional damping when the seat is leveled outside the normal leveling zone. The degree of additional damping provided is a function of the distance the seat exceeds the normal leveling zone.

1. In a seat suspension system having a first endstop limit, a second endstop limit and means for controlling the seat displacement, a method for limiting endstop collisions, the method comprising the steps of:(a) sensing the relative position of the seat; (b) determining the relative seat velocity; (c) calculating a control signal by multiplying the seat velocity by a gain factor; and (d) transmitting the control signal to said displacement control means to increase the damping to the required level.
