Abstract

An inflatable survival vest includes an inflatable bladder having an inflation inlet through which a gas is input to inflate the bladder. The bladder is configured in the shape of a vest. The bladder has a plurality of parallel seams that divide the bladder into tubular channels. The tubular channels cause the vest to have a wavy outwardly facing surface with crests and troughs and a wavy inwardly facing surface with crests and troughs. An inner air chamber is positioned along the inwardly facing surface of the bladder. A shell with limited stretch-ability overlies the inflatable bladder, thereby limiting outward expansion of the bladder such that the bladder is adapted to expand inwardly pressing the inner air chamber against a body of a person wearing the bladder.
