The invention relates to a propellant cage () for an inflator, especially for a tubular inflator of an airbag module, comprising a substantially tubular base () which forms, on the one hand, a gas inlet opening () and, on the other hand, a gas outlet opening () along its longitudinal axis (L), wherein at least one lateral gas flow opening () is configured in a circumferential wall () of the base (), wherein the base () includes a radially outwardly extending collar () having at least one frontal gas flow opening () in the area of the gas flow opening ().

Propellant cage for an inflator, inflator comprising such propellant cage operating method and method of guiding a shock wave of an inflator

A propellant cage () for a tubular inflator (), especially for a tubular inflator () of an airbag module, for forming a propellant chamber () and a flow passage () of the tubular inflator (). The propellant cage () is in the form of a propellant cage spiral spring () having a gas inlet-side end () and a gas outlet-side end (), the gas inlet-side end () having a smaller cross-section than the gas outlet-side end ().

Propellant cage and packing element for a tubular inflator

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.
