ABSTRACT:
A seat assembly for a motor vehicle includes an air suspension system for effectively isolating the occupant of the seat from shock, vibration and inertial forces directed along both a vertical axis and a horizontal axis. A base plate is mounted to the floor of the vehicle and supports first and second pairs of sleeve bearings on opposed sides of a box-like housing. The housing itself is attached to a pair of guide rods which cooperate with the sleeve bearings to provide fore and aft movement of the housing. Springs operating in cooperation with a first horizontally disposed air bag serves to dampen out inertial forces on the vehicle seat. The seat itself it support atop a vertically oriented air spring and a plurality of hydraulic vibration dampeners that tend to cushion vertically directed force spectors acting upon the seat and its occupant.
