ABSTRACT:
A safety bag formed of a flexible foldable material occupying a small volume when collapsed and expandable to form a hollow enclosure substantially completely surrounding an interior space by means of interconnected channels arranged along the surface of the shell and adapted to receive and retain a pressurized gas. The interior is filled with ambient air during the expansion process and its volume is preferably at least five times and, in some cases, of the order of forty times greater than the total interior volume of the inflatable channels. Means, including the shell itself, serve to limit the extent of inflation of the channels.
