Abstract:
A molded shock-absorbing cushion device, comprising:(a) an inflatable cushion having two superimposed synthetic plastic gas permeable material sheets peripherally sealed together and bounding an interior space with an inlet; (b) a plurality of recesses formed solely in one of the sheets, the other of the sheets being substantially flat and smooth and devoid of recesses, each recess being bounded by walls extending from said one sheet in an inward direction toward the other of the sheets to resist compression along the inward direction, said walls subdividing the interior space into compartments; and (c) means at the inlet for admitting a fluid under pressure into the compartments to inflate the cushion, said other sheet being generally flat and smooth both prior to, and after, inflation to present a smooth, unbroken surface for surface contact against a surface to be cushioned wherein said recesses include elongate grooves extending entirely across the cushion device to enhance foldability of the cushion device.
