The gas generator for inflating an air bag comprises an inflating gas source and a gas outlet orifice. It comprises means for leading the gas through second outlet orifices when the system is initiated when it is not in use. There are also means for sealing the second orifices when the device is in use so that when the system is initiated the gas passes through the first outlet orifice. The generator comprises a cylindrical tube part (201) comprising an end on which the airbag can be connected. The tube comprises a central channel (220) defining a gas flow section, in a given direction (f1) between an upstream end connected to the gas source and a downstream closed end constituting a solid end section (208). The first orifice is formed through the solid end section and the second orifices pass through a lateral wall (202). |
