ABSTRACT:
A self-collapsible, inflatable device consists of a sheet made of a thermoplastic material having a memory set such that it forms into a coil when unrestrained and at least one inflatable member, semi-rigid when inflated and capable of being coiled when deflated, the inflatable member being mounted on a surface of the sheet which assumes a concave shape when the sheet is allowed to form into a coil. In one preferred embodiment the sheet includes upper and lower sheet members joined at their respective leading edges and the inflatable member is attached to the lower surface of the upper sheet and the upper surface of the lower sheet. The inflatable member and the upper and lower sheets are arranged such that the self-collapsible device coils itself when the inflatable member is deflated.
