Abstract: A seat belt retractor, with a belt shaft mounted rotatably in a frame, a blocking device for blocking the belt shaft in an extension direction of the seat belt, a control device having a control disc with a toothing for activating the blocking device, an electric actuator with a first blocking lever, which is spring-loaded into the toothing of the control disc in an engagement direction, an ECL blocking lever which, in a first position, blocks the first blocking lever of the actuator during a first belt band extension in a position in which said blocking lever does not engage in the toothing of the control disc, and an LC blocking lever which, in a first position, blocks the first blocking lever of the actuator when a predetermined belt band extension length is fallen short of in a first position.
