Abstract

This invention relates to an inflation device for automobile safety equipment with a container in which a charge chamber for acceptance of a gas-producing charge and a discharge chamber with a discharge opening for connection with the safety device are provided, where a separating wall with an inside opening separates the two chambers axially from each other and is connected in a fluid-tight manner with a wall of said container by interlocking connecting means. According to the invention, such an inflation device excels through the fact that the connecting means are formed elastically in the axial direction in such manner that, when a predetermined pressure is reached in the charge chamber, they fail elastically and the separating wall is movable in the axial direction in the discharge chamber. The connecting means are released free of any radial expansion of the container wall.
