ABSTRACT:
A gas generator is provided with an outer tube and an inner tube arranged coaxially within the outer tube. The pressure gas-generating charge is accommodated in the inner tube, the charge being ignited by an ignition unit. The generator is closed at the ends in a gas tight manner by closure covers, which are surrounded laterally by the end sections of the outer tube. On the inside of the closure covers there is in each case a recess for accepting the ends of the inner tube. The recesses hold the inner tube centered in the outer tube. Each cover is further provided with a peripheral groove, in which interior projections, directed inwards, and formed by multiple notching by means of a notching tool, engage. These projections, for their part, are arranged on the inner peripheral surface of the outer tube in the end sections thereof.
