Abstract
A buoyancy compensator assembly for a diver is provided with a vest having an inner gas impermeable layer adapted to face a wearer and a congruently shaped opposing gas impermeable outer layer. The peripheral edges of the inner and outer layers are sealingly bonded to each other. The vest has an opening through a back portion of the vest. A backpack for removably retaining a longitudinally extending breathing gas tank has a baseplate generally disposed within the opening. Attached to the periphery of the baseplate is an edge. The edge is disposed between and integrally bonded to the inner and outer layers whereby the layers form a chamber to be selectively inflated to adjust the buoyancy of the diver. A restraining sheet is located between and alternately attached to the inner layer and outer layer to form aligned bands. The sheet forces the inner layer to curve inward about the sides of the diver when the chamber is inflated. The backpack is constructed so that when the breathing gas tank is strapped onto the backpack the baseplate curves to fit about the back of the diver.
