Abstract: Gas generator comprising:



a chamber with an outlet port,
breakable sealing means.
pressurized gas stored in the chamber,
an insert nozzle positioned in the chamber, comprising at least three intermediate orifices and positioned between the gas outlet and at least some of the pressurized gas, characterized in that the insert nozzle is arranged to deform after the breakable sealing means are ruptured, during the application of a pressure difference between a downstream face and an upstream face of the insert nozzle exerted by said at least some of the pressurized gas.

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.

Abstract: A gas generator includes at least one pyrotechnic substance, at least one subassembly formed at least of a first component and a second component, and at least one third component fixed to at least one of the first component and of the second component. The this component and one of the first component and of the second component each comprise an indexing interface arranged to temporarily block at least two degrees of freedom between the third component of the one of the first component and of the second component.
