Embodiment Construction

[0035] figure 1 Shown is a belt retractor 10 comprising a belt reel 12 , which is rotatably mounted on a frame 14 . In addition, a housing cover 15 is attached to the frame 14 . For clarity, the vehicle seat belts are not shown.

[0036] Figure 2aA side view of the belt retractor 10 is shown with the housing cover 15 removed. A sensor 16 for sensitively blocking the belt reel in the vehicle and a mechanism 17 for deactivating said sensor 16 can be seen here.

[0037] A pinion (not shown) is arranged on the tape reel 12 in a relatively non-rotatable manner. The pinion cooperates with the gear wheel 18 . The traction rod 22 is rotationally connected to the gearwheel 18 via the friction clutch 20 and thus via the friction torque prevailing in the friction clutch 20 .

[0038] The drawbar 22 is coupled to a rotatably mounted locking lever 24 which is pretensioned in the direction of the drawbar 22 by a spring 26 . The locking lever 24 forms the deactivating element for the...

Abstract

Described is a belt retractor for a vehicle safety belt, comprising a belt reel (12) rotatably mounted in a frame, a sensor (16) for blocking the belt reel (12) in response to the vehicle, and a mechanism (17) for deactivating the sensor (16). According to the invention, the belt reel (12) acts on the mechanism (17) for deactivating the sensor (16) by means of a gear (18), which is rotatably mounted on the frame, and a rocker arm (22) and can move the mechanism (17).

Description

technical field [0001] The invention relates to a belt retractor for a seat belt of a vehicle, comprising a belt reel rotatably supported in a frame, a sensor for a vehicle-sensitive locking of the belt reel and a mechanism for deactivating the sensor . Background technique [0002] Belt retractors for vehicle seat belts are generally known from the prior art. The vehicle seat belt here can be selectively wound onto or unwound from the tape reel. [0003] For safety reasons, deployment of vehicle seat belts must be prevented in certain situations. This is especially the case when the vehicle is involved in an accident or otherwise decelerates strongly. The vehicle seat belt must effectively retain the vehicle occupant buckled by the vehicle seat belt in his seat in such a situation. [0004] As already mentioned at the outset, known belt retractors have sensors for this purpose. The sensor usually has an inertial mass, which is usually implemented as a metal ball. In t...
