Abstract
Suspension system for wide seats having a rigid occupant supporting member has a pair of parallel, rotatable drums mounted to a rigid portion of a vehicle at a fixed horizontal distance from each other. A plurality of flexible web or cable support members attached to each of said pair of drums are attached to vertically spaced attachment points on the adjacent rigid occupant supporting member portion of the suspended seat and insure that the seat moves up or down as the drums rotate. Those flexible support members which are attached to upper attachment points on said rigid supporting member are in contact with lower peripheral surfaces of the adjacent drum when the seat is in its mid-ride position while the remaining flexible support members which are attached to lower attachment points on said rigid supporting member are in contact with upper peripheral surfaces of the adjacent drum when the seat is in its mid-ride position. The drums are linked together for simultaneous rotation at the same peripheral surface speed by a flexible member which insures that the seat's occupant supporting member will move up and down uniformly no matter how unevenly it is loaded. A yieldable means such as an air spring resists downward forces applied by the seat and its occupant(s). In a modification, the drums are located under the front and rear portions of a seat where they serve as fore and aft isolation means in addition to providing vertical isolation.
