Abstract The specification discloses seat structures comprising a lightweight frame having a generally horizontal seat portion and a somewhat vertical back portion. The frame is preferably formed from metal tubing to have an inherent resiliency or springaction. Attached to the seat and back portions of the frame are inflatable cushion members formed from air impervious sheet material, such as plastic, rubberized fabric or the like. Preferably, the cushions have individual sections which are separately inflatable whereby the contour and firmness of any seat can be varied. In one embodiment, the seat and back portions of the frame have U-shaped tubular portions and the inflatable cushions have pocket-like recesses adapted to receive the Ushaped portions. In a second embodiment, the frame is formed from sheet metal, or molded from plastic and provided with a plurality of openings. The cushions include outwardly extending, resilient or deformable members spaced to correspond to openings in the frame. The members are sized slightly larger than the openings so that the cushions can be attached to the frame by deforming the members and forcing them into or through the openings.
A seat structure comprising: a generally horizontal base frame; a generally vertical back frame extending upwardly from said base frame; said base frame and said back frame being interconnected and formed from resilient metal tubing, the tubing forming said base frame and said seat frame being bent generally bent to provide at least one generally U-shaped central portion and separately inflatable air cushion members covering said base frame and said back frame and connected thereto: said air cushion members each including a pocket which extends inwardly from the outer surface and is surrounded by in-flatable portions of said cushion; and, said U-shaped portions of said base frame and said back frame are received in said pockets.
