    摘要： An inflator for a protective device in a vehicle includes a diffuser (10) forming a substantially rotation-symmetric external housing of the locator with a dosing member (12), wherein the diffuser (10) includes a plurality of discharge orifices (78) arranged in a row, and which are of circular shape. The inflator also includes a circumferential wall (18, 22) which surrounds a combustion chamber (44) and a filter (46) which extends at least partially along the wall (16, 22), wherein the wall (16, 22) has at least one supporting portion (124) which constitutes an axial support for the filter (46) and is integrally formed with the wall (16, 22), and wherein either plural supporting portions (124) are formed by embossed beads, the heads being spaced apart from each other in circumferential direction, and wherein a supporting portion (124) is formed by a completely circumferential embossed bead.

    摘要： A gas generator (10) comprises an outer housing, which has at (east two housing parts (12), which are connected to each other, in the form of a diffuser bowl (14) with outflow openings (16) towards the outside and a cover (20) directly connected to the diffuser bowl (14). Inside the gas generator (10), at least one first and one second combustion chamber (30, 36) are provided, wherein the first combustion chamber (30) is delimited by an inner wall (32) and the second combustion chamber (36) is located within the space delimited by the diffuser bowl (14) and the cover (20). The diffuser bowl (14) and/or the cover (20) comprise a section (24) that is shaped, in particular deep-drawn, into an indentation, forming at least partially a circumferential section of the inner wall (32).

    摘要： The invention relates to a hybrid inflator especially for a vehicle safety system, comprising an igniter (10), a combustion chamber (16) including a propellant charge (18) which is separated from the igniter (10) by a first bursting element (14) held by a bursting element holder (13), and comprising a compressed gas tank (20) filled with compressed gas and having at feast one discharge opening, the discharge opening being closed by a second bursting element (24) and the compressed gas tank (20) being fluid-communicated with the combustion chamber (16) so that the compressed gas surrounds the propellant charge (18). The invention excels by the fact that the bursting element holder (13) at least in portions delimits an ignition chamber (30) containing a booster charge (15), wherein a shock wave (SW) for opening the second bursting element (24) can be formed only when both the igniter (10) and the booster charge (15) have been ignited and, respectively, activated. The invention further deals with an airbag unit and a vehicle safety system comprising said hybrid inflator or said airbag unit. Moreover, the invention states a method of forming a shock wave within a hybrid inflator.
