Abstract
The mechanical sensor of a pretensioner in a safety belt restraining system is secured against unintentional release in the unassembled state by a pin which engages a vehicle-sensitive inertia mass and which blocks movement of the inertia mass. The pin is connected via a cable to a rotatable member which is received in a bearing housing. The rotatable member has the form of an annular disc with a central bore through which a mounting screw can be inserted. On tightening the mounting screw the rotatable member is also turned so that via the pulling cable the pin is withdrawn and the securing of the inertia mass is cancelled.
Claims23
A safety mechanism for a vehicle safety apparatus such as a pretensioner in a vehicle safety belt restraining system or a gas bag restraining system in a vehicle, the vehicle safety apparatus having a movable actuating member, said safety mechanism comprising:
- blocking means for blocking actuating movement of said actuating member;
- said blocking means including a blocking member connected by a sheathed cable to a rotatably mounted component rotatably driven by a mounting screw for said safety mechanism and jointly rotatable with said mounting screw on tightening thereof;
- rotational movement of said component moving said blocking member from a blocking position into a release position to enable actuating movement of said actuating member;
- and
- spring means for biasing said blocking member into its blocking position, said spring means, on loosening said mounting screw, automatically returning said blocking member to its blocking position.
A safety mechanism for a vehicle safety apparatus such as a pretensioner in a vehicle safety belt restraining system or a gas bag restraining system in a vehicle, the vehicle safety apparatus having a movable actuating member, said safety mechanism comprising:
- blocking means for blocking actuating movement of said actuating member;
- said blocking means including a blocking member connected to a rotatably mounted component rotatably driven by a mounting screw for said safety mechanism and jointly rotatable with said mounting screw on tightening thereof;
- rotational movement of said component moving said blocking member from a blocking position into a release position to enable actuating movement of said actuating member;
- and
- said mounting screw having a shank, said rotatably mounted component formed as an annular member extending around said shank of said mounting screw.
