A gas generator for a safety system is disclosed. The gas generator comprises at least one pyrotechnic substance arranged to produce gases; a first part; a second part; a third part; and a fourth partseparate 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 orderto allow the first and second parts to be simultaneously friction-welded to the third part.

    本发明公开了用于安全系统的气体发生器,该气体发生器包括:至少一种烟火物质,该至少一种烟火物质被布置成产生气体;第一部件;第二部件;第三部件;以及与先前部件分开的第四部件,该第一部件和该第二部件摩擦焊接到该第三部件。该气体发生器的特征在于该第四部件包括:第一界面,该第一界面用于与该第一部件定位在一起,以及第二界面,该第二界面用于与该第二部件定位在一起,以便暂时阻挡该第一部件和该第二部件之间的至少一个自由度,从而允许该第一部件和该第二部件同时摩擦焊接到该第三部件。
