ABSTRACT:
The invention relates to a gas microgenerator intended more particularly for automobile safety. The microgenerator (1) comprises an igniter support (2) provided with a central bore (3) extended by a cylindrical neck (4) in which an igniter body (5) is fixed by crimping, two electrodes (8, 9) passing through this igniter body. A resistor (10) embedded in an ignition composition (11) links the two electrodes together. A shatterable case (13) containing an ignition powder (14) surrounds the resistor and the ignition composition. The electrodes in their lower part include cutting slots into which are inserted two electrically conducting sheathed wires (20, 21) coming from a supply cable (19). A closure piece (24), which is snap-fitted into the central bore locks the microgenerator. The microgenerator can be used to operate a belt retractor or to ignite a generator intended to inflate an airbag.
