A seat belt retractor for a seat belt device for a vehicle with a belt shaft that is rotatably supported in a belt retractor frame, and a blocking device with a locking catch. A sensor device () is provided with a first blocking lever () which actuates the locking device based on vehicle deceleration via movement of a first blocking lever (). A second blocking lever () supported on the belt extractor for fixing the first blocking lever () when there is a predetermined belt extraction length. A counter gear () driven by the belt shaft is provided being formed by an eccentric () that drives the belt shaft and a wobble plate () having a first toothing () that can be driven by eccentric () to perform a wobbling movement.

Belt retractor for a seatbelt device

A self-locking belt retractor for seat belts having a belt-strap-sensitive control mechanism with a control disc coupled to the belt shaft to control a locking element, by means of a pin moveably in an oblong hole in the control disc. The control disc carries an inertia element that, when triggered, radially swivels to lock the retractor belt shaft engages into a stationary toothed section. A control clip has two spaced apart legs on a friction mount between a blocking position of the inertia element and a release position. A follower forms stop surfaces engageable with the clip legs to carry the control clip during the rotation of the control disc belt winding direction a belt extension direction. The control clip releases the inertia element in the release position. One spring leg extends with an end into the movement path of the pin in the oblong hole.

Self-locking belt retractor anti-rattle action on its belt-strap-sensitive control system that is effective in the winding direction of the belt shaft

A self-locking belt retractor with a belt shaft which is mounted rotatably in a frame having a belt-sensitive a blocking device. A disc cam () mounted rotatably on the belt shaft, is pretensioned by a spring in the extension direction of the seat belt and on which an inertial mass () is mounted pivotably about a pivot axis (S). A projection () limits relative movement between the inertial mass () and the disc cam () is provided on the inertial mass () and/or on the disc cam ().
