ABSTRACT:
A lightweight, economically constructed support structure for vehicle seats having a minimum number of components having a substantial commonality and a number of interchangeable components. The seat support structure includes a pair of spaced horizontal tubular members which extend beneath individual seating stations. These tubular members are maintained in a predetermined spaced relationship by a multiplicity of spacing members each located adjacent to the individual seating stations and adapted to support the pivotable armrest situated between each seating station. The horizontal tubular members and associated structure support a diaphragm of fabric or the like at each seat location which is stretched between and fastened to the forward tubular member and a plate member supported and located in proximity to the rear tubular member. These diaphragms are adapted to support the individual seat cushions at each seat location. Each of the spaced tubular members is also provided with a plurality of spaced apertures which facilitate the reception of fastenings which can be used to secure seat legs to the tubular members at different locations in order to locate the leg positions so that they will correspond to varying seat locking track locations that may be provided in the floor of a vehicle in which the seat structure may be mounted. The seat legs are identical to one another and have a bifurcated lower end which can accommodate a seat track locking fixture and supporting members that are fixed to the leg structure to furnish added rigidity thereto.
