The invention relates to a pyrotechnic gas generator (1) intended for motor vehicle safety. The generator (1) comprises a hollow cylindrical body (2, 3) having gas outlet orifices (4) and being closed by a ring (6). The generator (1) contains an annular pyrotechnic charge (18) arranged around an ignition device (14, 16, 17) carried by the closure ring (6). The charge (18) essentially consists of a silicone binder and a mixture of ammonium perchlorate and of sodium nitrate. Its dimensions are less than the internal dimensions of the body of the generator,...


[ We claim:] [1.] Pyrotechnic gas generator (1) for an air bag intended to protect the occupants of a motor vehicle, comprising in particular:i) a hollow cylindrical body consisting of a circular base (2) extended by a cylindrical lateral wall (3) having, in proximity to the base (2), orifices (4) which connect inside and outside of the said hollow body, said wall (3) being terminated by a thinned end (5) and having an external shoulder (29) located under the orifices (4);ii) a circular closure ring (6) crimped into said thinned end (5) of the lateral wa...
