Abstract
The gas generator has two tubes, coaxial to each other, with different diameters, between which there is formed an annular intermediate chamber. The inner tube is filled with gas-producing material in the form of pellets, which develops pressure gas when ignited, the gas emerges via openings in both tubes. Projecting into the inner tube there is an ignition device, which extends through the cylindrical walls of both tubes. The ignition device is held by a ring or tubular holding body, which is substantially shorter than both tubes and fills out the intermediate chamber between both tubes. Both tubes are provided with peripheral openings aligning with each other, and the holding body has an installation through-hole, into which the ignition device is positioned. The holding body has furthermore a slot. The ignition device is held in a reliable manner by means of the holding body.
