Abstract
A belt retractor (10) for a vehicle seat belt, includes a frame (12) provided with a plurality of blocking teeth (22), a belt reel (14) being rotatably supported in the frame (12) and a blocking tooth system (24) adapted to be engaged with the blocking teeth (22). A control lever (28) pivoted on the frame (12) and accommodates the belt reel (14). A sensor (34) actuates when a predetermined vehicle deceleration is exceeded. A control tooth system (26) with which the sensor (34) is adapted to interact is provided at the belt reel (14).

A belt retractor (10) for a vehicle seat belt, comprising a frame (12) provided with a plurality of blocking teeth (22), a belt reel (14) rotatably supported in the frame (12) and a blocking tooth system (24) adapted to be engaged with the blocking teeth (22), a control lever (28) being pivoted on the frame (12) and rotatably supporting the belt reel (14) and a sensor (34) which actuates when a predetermined vehicle deceleration is exceeded, wherein a control tooth system (26) with which the sensor (34) is adapted to interact to stop rotation of the blocking tooth system relative to the blocking teeth is provided at the belt reel (14), the control tooth system being non-rotatably connected to the blocking tooth system.
A belt retractor for a seat belt, comprising:
- a frame having a plurality of blocking teeth;
- a belt reel;
- a control lever pivotably mounted to the frame and supporting the belt reel for rotation relative to the frame about an axis of the belt reel;
- a blocking tooth system rotatable with the belt reel relative to the frame about the axis of the belt reel, the blocking tooth system engaging the blocking teeth to block rotation of the belt reel relative to the frame;
- a control tooth system non-rotatably connected to the blocking tooth system;
- and
- a sensor that actuates when a predetermined vehicle deceleration is exceeded, the sensor interacting with the control tooth system to stop rotation of the blocking tooth system relative to the blocking teeth.
