摘要： The invention relates to a gas generator comprising: a primary chamber (3) for storing and burning a primary pyrotechnic compound, having a nozzle (17) for expelling the products of combustion of the primary compound in the form of a primary jet in an axial direction of the generator; an ignition system (11); a secondary chamber (5) for storing and breaking down a secondary compound, the primary jet driving the breakdown of the secondary compound, the secondary chamber having an inlet opening (14) for the primary jet; at least one stabilization zone communicating with the secondary chamber and with the outside of the generator. In a first version, the stabilization chamber (12) extends at least partially around the primary chamber. In a second version, the stabilization zone extends downstream of the secondary chamber and a shield is formed facing the primary jet at the wall dividing the secondary chamber from the stabilization zone.

摘要： The present invention relates to a gas generator (1) for a safety system. This generator comprises an explosible change formed at least by a primary pyrotechnic compound, in a first chamber (10), initiated by at least one initiator (11) provided with a reinforcing charge and a secondary compound, in a second chamber (20) provided, in a first zone (30) close to said first chamber, with peripheral orifices (17) for discharging the gases and containing, in a second zone (40), said secondary compound. A means (70) forming an obstacle to the passage of the gases is installed in said second chamber between said first and second zones, said obstacle-forming means allowing the gases to pass into a central part and forming an obstacle to their passage into a peripheral part, with sufficient transparency for the gas interaction volume to be slightly confined.

摘要： The invention relates to a gas generator comprising a resistant frame capable of maintaining its integrity during the operation thereof, wherein said frame defines a primary chamber (3) containing a primary pyrotechnical compound such as a propellant, a secondary chamber (14) containing a secondary compound such as ammonium nitrate with an additive, and a stabilisation area (22). The frame portion defining the secondary chamber comprises at least one wall (15, 16) that is made lighter using at least one gas-tight solid polymeric material, said polymeric material(s) being used for forming a lighter wall having a mechanical-property decay temperature higher than 120°C and having mechanical characteristics such that the secondary chamber has an inner volume during operation lower than four times said inner volume under rest conditions.

摘要： The invention relates to a gas generator (1) that includes: a gas generation chamber (10) for storing and decomposing a gas generating compound (11), wherein the product from the permanent-mode decomposition impart to the compound an amount of energy that is not sufficient for sustaining said decomposition; a stabilisation area (8) in communication with the gas generation chamber via at least one discharge opening (14) for discharging the gas generated into the stabilisation area, and with the outside via gas release holes (9); an energy supply device (4) in the form of at least one non-pyrotechnic energy beam such that each beam ensures an energy supply between the gas generating compound and the discharge openings of the stabilisation area in order to increase the energy density of the gases resulting from the decomposition as a complement of the energy released by said decomposition.

摘要： The invention relates to a device comprising a system for the generation of gas, in particular for use of a safety element for the protection of goods and/or people, in particular for the protection of at least one occupant of a vehicle. The gas generation system is connected to said safety element, for example, an inflatable cushion and comprises an explosive charge formed by at least one primary pyrotechnical composition in a first chamber, initiated by at least one initiator having a reinforcing charge and a second composition. The first composition comprises at least one propellant, for example a double-base propellant or those based on nitrocellulose, nitrammites, lova type or those conventionally used for inflatable safety cushions, the oxygen balance of which has optionally been adjusted. The invention is characterised in that the second composition in a second chamber comprises an oxidant which provides only gas on decomposition, at least one reducing additive with a nitrogen contributing effect, said additive present in a mass proportion of less than 70 % of the mass of the primary/secondary combination.
