This can occur, for example, when the seat belt retractor is switched between ELR (emergency locking) and ALR (automatic locking) operation, or when the seat belt retractor is installed in a It can also occur when the belt shaft should in principle be locked when the belt is pulled out to a defined length, or from a defined belt retraction length the belt shaft should not be locked even when the mass of inertia is deflected

Embodiment Construction

[0025] exist figure 1 with figure 2 A housing cover 1 for a seat belt retractor of a seat belt arrangement of a vehicle, which is not shown, is shown in the assembled state and in an exploded view. Since the other parts of the seat belt retractor are not changed by the invention, these parts will not be shown and described below, and only the components which cooperate with the components of the invention will be described.

[0026] The housing cover 1 is fixed on the outer edge side of a leg of a U-shaped belt retractor frame of the belt retractor, in which belt shaft is rotatably mounted. The housing cover 1 is primarily intended to cover a locking device having a locking catch supported on a belt shaft which, when actuated, is controlled to engage in a fixed toothing of the seat belt retractor frame and This locks the spool in the pull-out direction of the webbing wound on the spool. Furthermore, the locking device comprises a control disc mounted rotatably on the belt ...

Abstract

The invention relates to a belt retractor for a seatbelt device for a vehicle, comprising a belt shaft which is rotatably mounted in a belt retractor frame that can be secured to the vehicle, a blocking device with a blocking pawl, a sensor device (2) with a first blocking lever (5) which actuates the blocking device by moving the first blocking lever (5) when a specified decrease of the speed of the vehicle is exceeded, and a second blocking lever (7) which is pivotally mounted on the belt retractor for fixing the first blocking lever (5) upon reaching a specified belt retraction length. A counter drive (3) which is driven by the belt shaft is provided in order to control the movement of the second blocking lever (7), said counter drive being made of an eccentric (27) which is driven by the belt shaft and a wobble plate (8) which can be driven by the eccentric (27) so as to produce a wobbling movement and which comprises a first toothing (19).

Description

technical field [0001] The invention relates to a seat belt retractor for a seat belt arrangement having the features of the preamble of claim 1 . Background technique [0002] Seat belt retractors are commonly used to retract the seat belts of seat belt arrangements in motor vehicles. Here, the belt retractor essentially has a locking device, which is actuated as a function of exceeding a predetermined acceleration value of the vehicle deceleration and the belt extension acceleration and thus subsequently locks the seat belt against further belt extension. sports. In order to actuate the locking device as a function of exceeding a predetermined value for vehicle deceleration, a sensor device (vehicle-sensitive sensor device) is provided which has an inertial body mounted on the sensor surface and resting against the locking lever. In addition, a control disc with a toothing is provided, which is rotatably mounted on the belt shaft of the belt retractor and which forces th...
