摘要： This generator comprises a tubular envelope (1) subdivided internally by a pair of partitions which delimit two combustion chambers situated at the ends of the envelope (1) and communicating, via orifices forming a nozzle, with a central plenum chamber (40), which itself communicates with at least one discharge opening (400) , the partition (5A) of at least one (30A) of the combustion chambers being furnished with a protective member which prevents the inadvertent igniting of the pyrotechnic charge (3A) that it contains by the combustion gases originating from the other chamber; this protective member is a thin and brittle plate (7) pressed against the partition (5A) of the chamber (30A) and normally blocking off the orifice (50A) thereof, which has zones of less resistance, such as grooves, capable of breaking under the pressure of the combustion gases produced in the chamber (30A) so that the parts (70 ') bordering these zones of less resistance deploy like petals towards the plenum chamber (40) , thus allowing the gases to pass (F) into the latter. Safety equipment for motor vehicles, particularly for the inflation of a protective airbag.
