ABSTRACT:
An inflatable air cushion has an integrally formed extension tube of zig-zag form with its free end attached to another cushion or to a pump assembly for inflating the cushion. By separating the limbs of the zig-zag tube, the cushions, or the cushion and pump assembly can be spaced apart at different distances to suit different applications. The pump may include a pressure limiting chamber integrated therewith for limiting the maximum inflation pressure of the cushion. In a preferred embodiment, the inflatable air cushion is shaped to fit a bicycle saddle.
