ABSTRACT:
A first belt of the invention--substantially hollow and worn about the waist--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 second belt of the invention--also worn about the waist--underlies the first belt and is coupled with it by a drawstrap. When the first belt is filled with the compressed gas, its length increases to form a horizontal tube which serves as a life preserver. Putting it over the head, about the neck and shoulders, and pulling down the end of the drawstrap snugly secures the first belt to the second belt (which continues to be worn about the waist) to convert it to a life vest. Couplings are provided on the first belt for maintaining a circular configuration across the chest area, while an elongated tube allows the wearer to orally inflate the vest should the compressed gas tend to leak over time, in keeping the head of the user out of the water.
