PURPOSE: A lifesaving vest containing an airbag for buffering is provided to prevent air gas from being leaked by being formed in two-fold structure. CONSTITUTION: A vest main body(1) is attached to a continuous airbag unit(7) composed of integrally formed chest airbag unit(2), a back airbag, and side airbags(4). Herein, the continuous airbag unit is formed by resins such as urethane and vinyl chloride while being formed in a two-fold structure of an outer bag and an inner bag. The outer bag and the inner bag are connected by high frequency sealing to be attached to the vest main body. Moreover, the continuous airbag unit contains gas inlet ports to inject gas to the outer bag and to the inner bag at one end of the continuous airbag unit. When gas is injected to the continuous airbag unit, the continuous airbag unit is expanded for supplying buffering operation.
