Abstract: The invention relates to a belt retractor surrounding a belt reel which is rotatably mounted in a frame, and comprising a force-limiting device with at least one plastically deformable first torsion rod, wherein the first torsion rod has a first end rotationally fixed to the belt reel and a second end rotationally fixed to a profiled head which can be blocked via a first blocking device in a fixed manner relative to the vehicle. The belt reel, the first torsion rod and the profiled head are arranged coaxially to one another and in series relative to one another.
