A cold gas generator for an airbag system has a storage device filled with a gas under pressure and provided with a gas outlet opening. A thin-walled sealing disk is provided which, in a rest state, seals pressure-tightly the gas outlet opening. A support device supports the sealing disk against a gas pressure of the gas acting on the sealing disk in a pressure direction. A triggering device acts on the support device. The support device has a pressure plate resting against the sealing disk and a support lever supporting the pressure plate and the sealing disk. The pressure plate and the support lever are configured as separate parts. A bearing supports the support lever such that the support lever receives forces in the pressure direction and is force-free transversely to the pressure direction. The triggering device acts on the support lever so as to cause pivoting about the bearing.

A method for filling a pressure vessel, for example an airbag system, with a gas or gas mixture. The filling is accomplished by cooling a pressure vessel, filling said vessel with at least one type of gas at a temperature which is higher than the boiling point thereof and closing the cold vessel. A pressure is produced in the filled and closed vessel by heating said vessel at an ambient temperature.
A method for filling a compressed-gas container, in particular a compressed gas container in an airbag system, with a gas or gas mixture, or for producing a gas mixture in a compressed gas container. The filling is accomplished by introducing a gas mixture, or at least one gaseous component of the gas mixture, into a cooled compressed-gas container in the form of a gas or liquid-cooled gas.
