SEAT-BELT RETRACTOR
First Claim
1. A seat-belt retractor having a locking system that is controlled by at least one vehicle-sensitive sensor, the vehicle-sensitive sensor of the type having an alignment mass for autonomous alignment and being configured to pivot on the seat-belt retractor when an angular installation position of the seat-belt retractor is changed, comprising a blocking device for fixing the position of the sensor when the seat-belt is extended that is friction-controlled by rotation of a belt shaft in an extension direction of the seat-belt, wherein the blocking device for the sensor includes a rotatably mounted blocking lever that is configured to be displaced from a blocking position which fixes the position of the sensor into a release position for the vehicle-sensitive sensor by a control lever that is coupled to the belt shaft by a friction coupling when the belt shaft rotates in a retraction direction which retracts the seat-belt enabling the sensor to undergo the autonomous alignment.

Abstract
In at least one embodiment of the present invention a seat-belt retractor is provided. The seat-belt retractor comprises a locking system that is controlled by means of at least one vehicle-sensitive sensor. The sensor has an alignment mass for autonomous alignment and is configured to pivot on the seat-belt retractor when the angular installation position of the seat-belt retractor is changed and when the seat-belt is extended, the sensor can be fixed in position by a blocking device. The blocking device is friction-controlled by the rotation of the belt shaft in the extension direction. The blocking device includes a rotatably mounted blocking lever which can be displaced into a release position for the sensor by a control lever that is coupled to the belt shaft by a friction coupling when the belt shaft rotates in a retraction direction.
