Abstract
A flotation device of the invention—of cell shape, substantially flat and of little bulk when deflated—is able to be filled with a compressed gas from a cartridge coupled with it so as to unfold and expand outwardly under action of the compressed gas which fills it. A belt of a jacket with an adjustable strap overlies the flotation device about the waist of a wearer and is coupled with it by a drawstrap. When the flotation device is filled with the compressed gas, its length increases to that of a life vest which can be placed around the head and about the neck when being donned. Pulling down the end of the drawstrap snugly secures the flotation device to the adjustable strap which continues to be worn about the waist. An elongated tube allows the wearer to orally inflate the vest should the compressed gas tend to leak over time, in keeping the head out of the water. The drawstrap is fixed to the waist strap at its inside center so as to bring end sections of the inflated flotation device towards one another when the drawstrap is being pulled, in tightening the life vest about the neck.
