Abstract
Abstract A multi-passenger vehicle seat having a generally horizontal seat frame and a generally vertical back frame is supported by a lower cantilever frame which comprises the horizontal seat frame and an inclined truss support frame. The horizontal seat frame includes two elongated horizontal stretcher members attached at one end to the wall of a vehicle and at least two cross frame members interconnecting the stretcher members at laterally spaced locations. The inclined truss support frame is located beneath the horizontal seat frame; and it includes fore and aft inclined frame members rigidly attached at their upper ends to the stretcher members respectively at locations spaced from the vehicle wall. The inclined support frame members extend downwardly from the seat frame and they converge toward each other. They are connected to the wall at locations above the floor of the vehicle. Additional support is provided by at least one diagonal strut across at least a portion of the back frame.
