Patent attributes
A cold gas generator for inflating a gas bag with help of a gas flowing out of a gas pressure vessel (7) with a discharge opening (1) closed off by a destructible membrane (2) arched in a direction opposite relative to the stored gas, with destruction of the membrane (2) occurring by a hot gas jet aimed at the membrane (2), which jet is produced by ignition of a primer (4) which can be activated by application of an electric pulse. In the filled state of gas pressure vessel (7), the surface (6a) of membrane (2) which is averted from the same is directed in an exposed manner into a room (12) which is in connection with the gas bag via at least one discharge opening (11) and through which the hot gas jet is guided which is focused on the membrane (2) via a nozzle chamber (5).
