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.
