Abstract:
1. A seat-belt retractor for a seat-belt 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, wherein an end of the blocking lever opposite an engagement tip has a bearing surface for a head formed by the control lever, the bearing surface being configured such that pivoting of the control lever causes the blocking lever to rotate.
