ABSTRACT:
A life preserver device which is constructed with an inflatable inner bag located inside an inflatable outer bag, with the device being deployed in the back of a seat in an aircraft. When extremely rough turbulance is encountered or a crash landing is envisioned, pressurized air is supplied to the inner bag through a break-away tube, causing the inner bag to inflate, expanding the outer bag around it from the back of the seat to act as an impact cushion. Following a landing in the water, the device may be removed from the seat by breaking the break-away tube and causing the device to deflate, put on by the passenger, and the inflatable outer bag reinflated by a gas cylinder prior to exiting the aircraft into the water.
