Abstract
The invention refers to a device permitting the flow of pressurized gas into a safety device, for example an air bag or a belt tightener, with a pressurized container for compressible gas with at least one opening, that is sealed with a gas-tight film covering, where the film covering is supported evenly, over at least a large part of its free surface, by a support device that can be destroyed or retracted in a targeted manner after triggering. To ensure that the gas-tight film covering is forcibly opened after the triggering of the device, a piece is provided that pierces or penetrates the film immediately after the triggering of the device, but before the support device moves.
