摘要： The present invention relates to an inflator for a safety device, in particular for a vehicle occupant restraint system, comprising a housing (1, 15; 22, 23), a combustion chamber formed in the housing and including a solid propellant (6) for generating hot gas, and a coolant (13) introduced into a predetermined flow path of the hot gas. The inflator in accordance with the invention is characterized in that the flow path of the hot gas passes through a nozzle (10) comprising a pitot zone (20) in which the hot gas emerging from the combustion chamber (21) has a high static pressure, and comprising a nozzle neck (19) in which the hot gas builds up a high dynamic pressure, and in that the coolant (13) is arranged in a sleeve-shaped reservoir (11) extending from the pitot zone (20) at least in part into the nozzle neck (19). The inflator in accordance with the invention permits an effective reduction in the exhaust gas temperature of the generated hot gas.

摘要： An inflator, more particularly for a vehicle occupant restraint system, has a tubular inflator housing which is closed off at its end faces and has radial exit ports via which the gas is able to exit the inflator. The inflator housing has in its interior at least one combustion chamber packed with propellant, at least one ignition unit for igniting the propellant in the combustion chamber and at least one filter which is located upstream of the exit ports. A filter insert featuring an outer housing is provided, the outer housing having a plurality of housing parts which at least partly surround the filter disposed in the filter insert. The outer housing together with its housing parts is radially secured to the inflator housing without the provision of an axial stop. The outer geometry of the outer housing and the inner geometry of the inflator housing permit total insertion of the outer housing or its housing parts in the axial direction into the inflator housing to different insertion depths when the outer housing is still in the non-secured condition.

摘要： A hybrid gas generator, in particular for vehicle occupant restraint systems, has at least one combustion chamber containing propellant and at least one igniter for igniting the propellant. The igniter comprises an igniting material and is spaced from the combustion chamber and from the propellant. The gas generator further has a pressure chamber filled with compressed gas, a common outflow opening for the compressed gas and hot gas generated on deflagration of the propellant, and a bursting disc closing the outflow opening and being able to be destroyed on activation of the gas generator. The igniter is arranged upstream of the bursting disc. The igniter and the bursting disc are arranged relative to each other in such a manner and are adapted to each other in their physical and chemical characteristics such that the destruction of the bursting disc is exclusively effected by a deflagration of the ignition material. A blast wave is generated on deflagration of the ignition material, at least a part of the blast wave being directed immediately onto the bursting disc.
