Abstract
Gas generator for a safety system, comprising: at least one pyrotechnic substance arranged to produce gases; a first part; a second part; a third part; and a fourth part separate from the previous parts, the first part and the second part being friction-welded to the third part. The gas generator is characterised in that the fourth part comprises: a first interface for positioning with the first part, and a second interface for positioning with the second part, such as to temporarily block at least one degree of freedom between the first and second parts in order to allow the first and second parts to be simultaneously friction-welded to the third part.
