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.
