Abstract
The generator (1) comprises a hollow cylindrical body (2) comprising a side wall (3) in which is crimped an impervious transverse partition (4) which separates an upstream combustion chamber (5) from a downstream combustion chamber (6), each combustion chamber (5, 6) having a pyrotechnic charge (7, 8). A neutralizing device consists, on the one hand, of a delay tube (21) fixed into the impervious transverse partition (4) and, on the other hand, of a pyrotechnic mixture (24) contained in the said delay tube (21). A safety assembly (31) is fitted around the necked region (28) and has pre-cut regions covering the combustion gases ejection nozzles. This adaptive pyrotechnic gas generator is intended to inflate an airbag and guarantees that any pyrotechnic substance is eliminated after operation.
