摘要:
The invention relates to a combustion chamber screen, especially for an inflator, that includes plural flow orifices and bent segments. In accordance with the invention, the bent segments are arranged around a center (M) of the combustion chamber screen so that in the circumferential direction of the combustion chamber screen (10) a waveform having plural wave peaks (12) and wave troughs (13) is formed.

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.

An inflator (10), especially for a vehicle occupant restraint system, comprising a combustion chamber (24) in which solid propellant (28) adapted to be burnt off while forming a gas is accommodated, a storage chamber (26) containing a pressure gas (30), an igniter (14) and a component (20) arranged between the combustion chamber (24) and the storage chamber (26). There is at least one flow communication between the storage chamber (26) and the combustion chamber (24). The component (20) includes an additional weakened zone (22) adapted to be destroyed upon activation of the inflator (10) so as to permit flow of gas from the combustion chamber (24) into the storage chamber (26).
摘要:
A pyrotechnic drive unit includes a cylinder tube (12) having an axial end (28), a piston (14) guided in the cylinder tube (12), a pyrotechnic igniter (16) which is adjacent to the piston (14) and constitutes the pyrotechnic drive, and a plastic part (18). The plastic part (18) is injection-molded to the igniter (16) and to the axial end (28) of the cylinder tube (12) so that it fastens the igniter (16) to the cylinder tube (12) and tightly closes the axial end (28) of the cylinder tube (12), the plastic part (18) engaging the piston (14) in an initial position of the drive unit (10).

摘要:
A gas generator, in particular for a vehicle occupant restraint system, has a pyrotechnical propellant (16), a combustion chamber (12) filled with the pyrotechnical propellant (16), an igniter (14) associated with the combustion chamber (12), a pressure chamber (18), filled with compressed gas, which is adjacent to the combustion chamber (12) and has a first opening (22) remote from the combustion chamber (12) closed by a first diaphragm (26), the diaphragm (26) being destroyed upon activation of the igniter (14), and a second pressure chamber (28) which is filled with compressed gas and has a second opening (34) closed by a second diaphragm (36). The second diaphragm (36) is likewise destroyed upon activation of the igniter (14), and the openings (22, 34) and the gas volumes of the pressure chambers (18, 28) are adapted so that compressed gas flows out from the second pressure chamber (28) for a longer period than compressed gas from the first pressure chamber (18) to increase a gas supply time of the gas generator (10). Further, a method of activating a vehicle occupant restraint system is described.
摘要:
The invention relates to an actuator subassembly (10) for a vehicle safety system comprising a pyrotechnic actuator unit (12) including an igniting portion (14) as well as a receiving element (16) forming a guide for the movable igniting portion (14) after activating the actuator unit (12). Further the invention relates to an airbag module of a vehicle safety system comprising said actuator subassembly (10) and a method of mounting a releasable tether (30) on an airbag module by means of said actuator assembly (10).
摘要:
A gas generator includes a generator housing (12), an igniter device mounting opening (18) which has an edge (22), an igniter device and a booster chamber (24) having a peripheral wall (26). The igniter device has a prefabricated igniter (16) sealed off towards the exterior, a booster charge (23) adjoining the igniter (16) and an injected plastic base (20). The edge (22) of the igniter device mounting opening (18) for fastening the igniter device to the generator housing (12) is embedded in the injected plastic base (20) during injecting. Connectors (14) leading to the igniter (16) are embedded into the plastic base (20) during injecting and the plastic base (20) continues in one piece into the booster chamber (24) by forming a peripheral wall (26) of the booster chamber (24) which the booster charge (23) directly adjoins.
