Abstract: A generator includes a tubular casing sealed by a bottom, with a wall crossed by discharge orifices. The generator further includes an adapter sleeve retained in the tubular casing by crimping, a pyrotechnic initiator, and a tubular filter covering the discharge orifices. A pyrotechnic charge is inserted between the adapter sleeve and the bottom. A charge securing arrangement includes, on the bottom side, a transverse partition, and on the open side, an open-worked washer urged towards the bottom. A sealing member is capable of breaking during combustion of the charge, to thereby allow the gases to escape out of the casing via the filter and the discharge orifices. After failure of the sealing member, the space occupied by the pyrotechnic charge is delimited axially by the open-worked washer and the bottom.

Abstract: This generator comprises a tubular casing (1) sealed by a bottom (10), with a wall crossed by discharge orifices (100), and includes: an adapter sleeve (3) retained in the tubular casing (1) by crimping; a pyrotechnic initiator (2); a tubular filter (7) covering the discharge orifices (100); a pyrotechnic charge (6) inserted in-between the adapter sleeve (3) and the bottom (10); means for securing the charge comprising, on the bottom side, a transverse partition, and on the open side, an open-worked washer (4) urged towards the bottom (10); a sealing member (8) capable of breaking during combustion of the charge, then allowing the gases to escape out of the casing (1) via the filter (7) and the discharge orifices (100); and in that after failure of the sealing member (8, 90), the space occupied by the pyrotechnic charge (6) is delimited axially by said open-worked washer (4) and said bottom (10). Safety equipment for automobiles, notably for inflating an inflatable safety bag.

Abstract: The present invention relates to a gas generator for a motor vehicle safety device. The generator includes at least a combustion chamber and a gas tank. The combustion chamber contains a pyrotechnic initiator and pyrotechnic charge for generating gas and including at least one oxidizing material. Combustion of the charge is triggered by the initiator. The gas tank is closed towards the combustion chamber by a capsule. The capsule is suitable for giving way during combustion of the charge in order to release the gas from the tank and exhaust it towards the outside. The combustion chamber contains a metal charge of at least one metal. The metal charge is distinct from the pyrotechnic charge.
