A gas generator () comprises a housing () in which a conical combustion chamber screen () terminates the combustion chamber (). On the front side, the combustion chamber screen () is closed by an end cap () to which a filter element () is connected which has one or more axially projecting centering extensions () on the edge of the filter bottom ().

Gas generator

The disclosure relates to a gas generator fora vehicle safety system. The gas generator has a longitudinal axis, an outer housing in the form of a compressed-gas container. In an inoperative state of the gas generator, the housing is filled with compressed gas. The housing is closed at one housing end with a closure element by a welded joint, which extends along the longitudinal axis from the welded joint into the housing. The housing has at least one bead for mechanically relieving the welded joint of load. A bead base of the bead is provided in a region of an axial longitudinal extent of the closure element.

The invention relates to a subassembly () of a vehicle safety system comprising a tubular casing () and comprising a fastening element () that includes at least one fastening hole () and a peripheral portion () curved at least in portions, wherein the peripheral portion () is connected at least at one connecting point () to the tubular casing (). In accordance with the invention, the peripheral portion () includes at least one breakthrough () and a coating passage () is formed at least in portions between the peripheral portion () and the casing (), wherein the tubular casing () includes at least in portions, especially on its entire exposed surface (), an anti-corrosion layer and/or the fastening element () includes at least in portions, especially on its entire exposed surface (), an anti-corrosion layer.

Subassembly of a vehicle safety system, vehicle safety system, vehicle safety device and method of manufacturing a subassembly of a vehicle safety system

The invention relates to a pyrotechnical actuator for a vehicle safety system comprising a cylinder () and a hollow piston () being displaceable relative to each other from an idle state to an activated state, wherein an igniter unit () being tightly connected to the hollow piston () is arranged inside the hollow piston (). The invention excels by the fact that in the idle state the hollow piston () is received in the cylinder () and in the activated state it protrudes at least partially from the cylinder () so that the actuator has a larger total length in the activated state than in the idle state. The invention further relates to an actuator and a vehicle safety system comprising such actuator as well as to an actuating method.
