The invention concerns a device for introducing pressurized gas into a vehicle safety device, preferably an air bag, with a pressure container (10) for compressed gas which has at least one opening (12) closed by a gas tight foil cover (14). The foil cover (14) is supported over at least a substantial part of its free surface area in a flat manner by a support device (16) which can be retracted in a direction perpendicular to the opening plane and is in turn supported on the pressure container (10). Via the foil cover (14) the compressed gas generates an outwardly directed force perpendicular to the opening plane, this force acting on the retractable support device (16) and being balanced with a reaction force of the latter. The device has a trigger arrangement (34) which can be activated in the event of an accident and brings about the retraction of the support device (16) such that the reaction force is canceled. When the trigger arrangement (34) has been activated, the support device (16) can first move a distance which is short relative to the opening diameter and then freely over a longer distance, perpendicular to the opening plane.
