    摘要： A gas generator comprises a housing and a propellant contained in the housing, the propellant, after activation, releases a fluid which is under pressure, and the housing has a first and a second housing part, which are movable relative to each other under pressure and form an overflow opening with a variable flow area depending on the pressure in the housing. Either the first or the second housing part, or both, have spacing means, the spacing means are designed so that in the case of the relative movement of the housing parts with respect to each other, a minimum value of the variable flow area is maintained.

    摘要： A gas generator comprises a container (12) filled with a pressurized fluid (14) and having an outflow opening (16), and a piston (20; 120) which is displaceably arranged in the container (12). The piston has a shutter opening (22; 122) dividing the container (12) into a first chamber (24) and a second chamber (26), the first and second chambers (24, 26) being filled with the fluid (14). The piston (20; 120) on activation of the gas generator (10; 100) and when the outflow opening (16) has been opened, is moved by a pressure prevailing in the second chamber (26) from a predetermined initial position (AP) in the direction towards the outflow opening (16) into an end position (EP) in which the end volume of the first chamber (24) is significantly reduced compared with the start volume of the first chamber (24). There is also proposed a method of operating such gas generator.

    摘要： The invention relates to a method for producing propellant compacts for use in gas generators for safety devices in motor vehicles by extrusion, comprising the following steps: mixing the constituents of the propellant and stirring the mixture into a paste with a solvent so as to form a plasticizable mass, extruding the plasticizable mass in order to form propellant compacts, and drying the propellant compacts in order to remove the solvent, a thickening agent which increases the viscosity being added to the solvent prior to pasting in a proportion of from 0.1 to 10% by weight, relative to the solvent, and the dried propellant compacts having a density of at least 70% of the theoretical density. The invention further relates to propellant compacts obtainable in accordance with this method.

    摘要： The invention relates to a gas generator comprising at least two combustion chambers filled with propellant charges and delimited by combustion chamber walls. The combustion chamber walls have outflow openings which in a non-activated state are closed by at least one applied membrane having an edge. One of an additional fastening device and a protective device is provided at least sections of the edge of the membrane. The device prevents a coming-off of the membrane from the combustion chamber wall.

    摘要： A vehicle safety system includes a module including an airbag and an inflator. The inflator includes a housing (12) in which a combustion chamber (16) containing a pyrotechnic propellant is arranged in which hot gas is generated and which housing includes at least one escape orifice (22) toward the environment of the inflator (10), as well as a coolant reservoir (24) arranged in the housing (12) in which coolant is accommodated prior to activation of the inflator (10) and which has at least one coolant outlet orifice (28′). The coolant outlet orifice (28) is arranged in direct vicinity of the outlet orifice (22). Upon activation of the inflator (10) coolant flows out of the inflator into the protection system and wets an adjacent wall (32) of the protection system against which also the hot gas is flowing.
