ABSTRACT:
For use as an escape device from burning buildings or for sporting use, a parachute canopy is supported in an open use position by an inflatable frame consisting of a network of inflatable lightweight flexible tubes. The inflatable framework has a portion which surrounds the waist of a user and also embodies an inflatable prelaunching positioning member. Bottled air or gas may be utilized to inflate the device through an inflation valve provided thereon. A restraining belt permits preinflation of the framework such that upon release the canopy expands almost instantaneously by the straightening of folded flexible tubes.
