ABSTRACT:
The invention is a suspension system for a vehicle seat with structural features allowing the suspension to be contained within the confined space available in recreational vehicles and light trucks. The invention includes a generally horizontal moveable platform pivotally attached at one end to a side of a seat frame. An air spring and shock absorber are mounted between the frame and the bottom of the seat to resiliently bias and damp the platform and therefore the occupant's vertical movement. The pivotal attachment is as far as possible from the center of the seat to permit maximum movement of the platform in an arc which closely approximates a straight, substantially vertical line. Means for automatically adjusting the suspension for occupants of different weights is included.
