Abstract: The invention relates to a load-bearing seat belt retractor for a seat structure of a vehicle seat. The seat belt retractor has two housing halves, between which functional modules of the seat belt retractor are arranged. One functional module is a belt spool with a winding axis, wherein a plurality of support plates oriented perpendicularly to the winding axis is provided on the functional modules, each said support plate having at least two locking noses, and the locking noses engage into corresponding locking holes in the two housing halves. The housing halves have beads and/or reinforcements directed toward the functional modules, and at least one section of a functional module and/or a section of a support plate is supported against the beads and/or reinforcements in at least one direction parallel to the winding axis.

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.
