A gas generator includes two reserves of reactive gases, an ignition device capable of being triggered in order to open lids of the reserves and initiating combustion of the reactive gases, and an orifice for letting out combustion gas towards the outside. The gas reserve, a device for diffusing the combustion gas towards the outside and the second gas reserve are successively positioned along a longitudinal direction. A guiding wall is provided in the reserve for guiding the pressure wave generated by the device up to the lid in order to open this first lid. The diffusing device includes a conduit for guiding the pressure wave from the first lid to the second lid so as to open the latter, and which communicates with the orifice.
