The invention relates to a pyrotechnic actuator assembly () for release of a retaining means () in a vehicle safety system () comprising a housing () composed of a first housing part () and a second housing part () fixedly connected to the first housing part (), the two housing parts () forming a substantially tight housing chamber (), a pyrotechnic charge () received in the housing chamber () as well as an electric ignition unit () for triggering of the pyrotechnic charge (), wherein the electric ignition unit () extends from outside of the housing chamber () through the first housing part () into the housing chamber (), and wherein the housing () includes a housing chamber portion () to which the pyrotechnic charge () is directly adjacent and includes a contact portion () for fastening the retaining means (). Moreover the invention also comprises an airbag module of a vehicle safety system including such actuator assembly ().

Pyrotechnic actuator assembly and airbag module comprising such actuator assembly

The invention relates to an actuator assembly for an airbag module in a vehicle safety system comprising an actuator () and a tensioning means (), wherein the actuator () includes a release member () which in the idle state of the actuator is connected to a retaining member () and is separable from the retaining member () by actuating a pyrotechnical ignition unit of the actuator () along a predetermined breaking point () so as to release a loop () of a tensioning means (). The invention excels by the fact that the loop () is formed between two tensioning means portions () which are interconnected directly at the predetermined breaking point () by a connecting means () such that the loop () is tensioned around the predetermined breaking point () in a self-fixing manner. Furthermore the invention relates to an airbag module, a vehicle safety system and a manufacturing method.
