Abstract: A method of manufacturing an inflator comprises the following steps: Providing a casing (12) that includes a tubular connecting portion (10) having a cylindrical wall (14), providing a closing member (19) that includes a closing portion (18) having a cylindrical contact surface (20) the cross-section of which has small oversize or undersize compared to the cross-section of the connecting portion (10), and axially pressing the closing member (19) into or onto the connecting portion (10) while simultaneously supplying electric current which flows between the cylindrical wall (14) and the contact surface (20) so that the closing member (19) is pressure-welded with the connecting portion (10).

Abstract: An airbag module for a vehicle occupant restraint system includes an airbag (22) and a gas generator (10) that is connected via at least one first outflow opening (18) to an airbag chamber (28), the airbag chamber (28) being at least partially formed by the interior of the airbag (22), an actuator unit (36) being provided on the gas generator (10) and, when the actuator unit (36) is activated, it releases a traction element (50) that causes a pressure reduction in the airbag (22), an activation of the actuator unit (36) also leading to an opening of a second outflow opening (20) in the gas generator (10), which vents generator gas to an environment without this vented gas flowing into the airbag chamber (28). Moreover, the invention relates to a method of restraining a vehicle occupant with such an airbag module.

Abstract: A gas generator (10) for use in a safety arrangement for vehicles comprises a housing (30) having at least a first and a second housing part (32, 34), the first housing part (32) comprising a cover section (38) and the second housing part (34) defining at least partially a propellant chamber (22) containing a propellant (26) for generating a fluid. The first and the second housing part (32, 34), under the action of the fluid are movable from a state of rest, in which the first and second housing parts lie partially against each other, into an operating state, in which the first and second housing parts are spaced apart from each other to form an overflow opening (46) for the fluid. A balancing element (56) is arranged in the propellant chamber (26) and acts between said housing (30) and said propellant (26) to limit movement of said propellant in said housing.

Abstract: 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.

Abstract: 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.

Abstract: The brake caliper unit has two caliper levers whose one ends are linked to brake pads and whose other ends are linked to a slack adjusting device extending between them. The central regions of the caliper levers are coupled to a housing, in which case the coupling point of one caliper lever is constructed as a simple rotary bearing. The coupling point of the other caliper lever is constructed as an eccentric transmission which can be operated by a brake cylinder held in the housing by a crank arm in the direction of the approach of the two caliper levers. The eccentric transmission has a shaft which is rotatable in the housing about an axis and which, with an eccentricity directed diagonally away from the brake disc carries a pin with the axis on which the caliper lever is disposed. The eccentric transmission permits a high power transmission ratio with relatively short caliper levers.
