Abstract
The invention relates to an igniter mechanism for a pyrotechnical gas generator of a vehicle occupant restraining system in which either an impact member or the gas generator for actuating the belt tensioning action is pretensioned by at least one spring so that the spring loads the impact member in a first direction against a stop. In addition the spring counteracts movement of the impact member in a second direction as a result of the forces of inertia acting on acceleration of the vehicle by means of a force which grows until a center position is reached. Force conversion means are provided to convert a torque generated by said spring into an axial force applied to said impact member.
