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.

A seat assembly adapted to be mounted on the floor of a motor vehicle comprising, in combination: (a) a base member attachable to the floor of a motor vehicle; (b) a box-like housing slidingly mounted on said base member for movement in a fore and aft direction relative to said motor vehicle, said housing having a floor and four mutually perpendicular side walls; (c) a vertically displaceable frame; (d) a seat supporting frame: [(e) slide means for mounting said seat supporting frame to said vertically displaceable frame;] (f) first air spring means supported in said box-like housing and engaging said vertically displaceable frame for controlling vertical movement of said vertically displaceable frame and said seat supporting frame; and (g) second air spring means operatively disposed between said base member and said box-like housing for controlling movement of said box-like housing in the fore and aft direction.
