Seat suspension system

A seat suspension system includes a vibration dampener adapted to operate over less than the full range over which a seat may be raised and lowered by a seat height adjuster, such as an air spring. The dampener may apply dampening forces which vary non-linearly, depending upon the extent a seat move...

Zusammenfassung:	A seat suspension system includes a vibration dampener adapted to operate over less than the full range over which a seat may be raised and lowered by a seat height adjuster, such as an air spring. The dampener may apply dampening forces which vary non-linearly, depending upon the extent a seat moves as a result of seat vibration. In several specific forms, the dampening mechanism is unlatched to permit relative movement of the seat and seat support mechanism relative to the dampener during seat height adjustment, with the dampener being relatched to again apply a dampening force. A mechanically simply seat leveling system may be employed to return the seat to a desired elevation in the event loading on the seat is varied, for example if a seat occupant gets up off a seat.
