ABSTRACT:
A seat assembly for use in vehicles includes an air spring suspension system, positioned behind the seat back, selectively operative vertically to move the seat relative to the vehicle a distance twice that of the air spring expansion movement. The seat is mounted on a movable frame that is supported by the suspension system from a fixed frame connected to the vehicle, with the travel of the movable frame being rectilinearly guided by rollers carried by the suspension system being received in trackways defined by cooperating channels on the fixed and movable frames.
