Abstract:
The present invention relates to a pyrotechnic gas generator for automobile safety, comprising a closed tubular casing (10) containing: at least one combustion chamber (C) containing a pyrotechnic charge (3) constituted by material in bulk, with combustion thereof being triggered by an initiator associated with the chamber (C); at least one plenum chamber (T) associated with said combustion chamber (C) and communicating therewith via at least one nozzle (130) that receives the gas generated by combustion of the charge (3) and serves to exhaust the gas to the outside via at least one discharge opening (100) formed in said casing (10). It is remarkable in that combustion chamber (C) and plenum chamber (T) are offset longitudinally, said nozzle (130) also extending longitudinally; that the zone (14) of the casing (10) situated in register with said combustion chamber (C) does not have any opening in communication with the outside.
