ABSTRACT:
An inflatable life vest comprises two sheets of polymeric material. The es of these sheets are sealed to form an inner cavity with a plurality of discrete, inflatable chambers disposed in a U-shaped pattern to define collar and chest portions of the life vest. A manifold connects to an inflation source and has a plurality of openings. A check valve connects each manifold opening with one of the chambers to permit inflation medium flow into the chamber and to block inflation medium flow outwardly from a chamber into the manifold. This construction isolates the chambers from one another so the rupture of one chamber does not affect the ability of the other chambers to be buoyant.
