Date Mar. 6, 1997The invention relates to a device for filling a restraint device, in particular an impact cushion (airbag) for the protection of the occupants of a motor vehicle, with the following features. The restraint device is filled by an inert gas or gas mixture stored in a pressure container; the pressure container has an outlet opening which is closed by a burstable membrane; a module for opening the membrane is associated with the outlet opening; the module has an ignition unit; the igniter case is surrounded by a toroidal propellant chamber; for the ignition of the propellant stored in the propellant chamber, the igniter case has, in addition to axial nozzles, further nozzles directed radially outwards and finally a flow control is provided which directs the hot gas, produced by the propellant, onto the membrane.
