ABSTRACT:
A strip-like body member in the form of a belt has one or more slits extending through it. A flat air-tight expandable bladder extends along the rear surface of the body member and is enclosed between such body member and a backing strip. A pocket is provided on the body member for removably holding a gas cartridge, and such cartridge is associated with an actuator arranged to release the contents of the cartridge. The cartridge communicates with the bladder and when opened by a pull line connected to the actuator, the bladder expands forwardly through the slits to form a buoyant life preserver. The body member is dimensioned and arranged to be passed through the conventional trouser belt loops so as to serve the dual purpose of holding up trousers and to be available as a life preserver when needed. The pull line is held normally in place by a releasable hold-down connector so as to be out of the way until needed. The body member has a transverse loop arranged to hold an opposite overlapping end portion thereof to protect the inflating apparatus.
