| 摘要 |
The invention relates to an ignition mechanism for a pyrotechnic gas generator (18) of an occupant restraint system for vehicles, in which a striking element (26) for triggering the tautening operation is pretensioned by at least one spring (56), in such a way that the spring (56) loads the striking element (26) in a first direction against a stop. Furthermore, as a result of the inertia forces taking effect during an acceleration of the vehicle, the spring (56) counteracts the movement of the striking element (26) in a second direction with a force increasing until a dead centre is reached. The spring (56) at the same time generates a torque which is converted by a transmission device (58) into an axial force loading the striking element (26). <IMAGE> |
