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 for seat belts having a belt shaft rotatably mounted in a housing frame and having a belt-webbing-sensitive actuation mechanism A control plate that can be deflected with a relative rotation between the belt shaft and the control plate The control plate bears a two-arm eccentrically mounted inertial mass A control clip is rotatably frictionally mounted on a bearing surface for the belt shaft. An actuator of the control plate engages two legs of control clip and forms contact surfaces for the legs for shifting the control plate in belt retracting direction as well as in belt extending direction. One of the legs projects during rotation of the control plate in the belt retracting direction into the pivoting path of a pivot arm of the inertial mass and releases the inertial mass with a rotation of the control plate in the belt extending direction.

Self-locking belt retractor with deactivation of its belt webbing-sensitive control system operating in the retracting 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 ().

Self-locking belt retractor

A safety belt retractor for motor vehicles having a locking system controllable in a belt webbing-sensitive and/or vehicle-sensitive manner, a locking pawl () mounted on the belt shaft () which locking pawl can be moved into engagement with a housing-fixed tooth, wherein the locking system can be deactivated at least within a range of a predetermined belt extraction length, wherein a locking element () is provided for deactivating the locking system which locking element can be moved depending on the belt extraction length from a first position releasing the locking pawl () to a second position fixing the locking pawl ().

Seat belt retractor with deactivatable locking system

A self-locking belt retainer with a vehicle-sensitive and/or seatbelt-sensitive actuatable locking device for the belt spool shaft, with a profile head as carrier of a locking element arranged so as to be movable with the retractor housing for locking of the belt spool shaft. A force limiting device in the form of a torsion bar is connected at its one end with the belt spool shaft and at its other end with the profile head is At least one axially projecting projection () is provided on the one of the components which are joined to one another (), which engages in at least one recess formed on the front side of the other component () and that in the annular space formed between the projection () and the inner walls () of the recess (), a clamping ring () is located between projection () and inner walls () of recess ().

Self-locking seat belt retractor

The inventive device for fixing a seat belt winder is fixed to the part of a motor vehicle. The plate of the housing of the winder is provided with at lest one fixing hole for receiving a screw connection which maintains the vehicle part embodied therein. The housing of said seat belt winder is arranged in such a way that it is rotatable with respect to the fixing hole of the vehicle part, thereby enabling the winder to be automatically oriented in a direction of a force of a belt which moves at an angle with respect to the axis of the shaft. Said fixing device is characterised in that the housing () of the winder is rotationally maintained on the holder part () which can be firmly connected to the vehicle part (). Said housing () is supported by the holder part () at a distance to the fixing hole () of the vehicle part () and is fixed to said holder part () in such away that the housing () of the seat belt winder is rotatable with respect the holder part () in an opposite direction to the action of a pre-set resistance.
