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.

Abstract: The invention relates to a seatbelt device for a motor vehicle, comprising: a diagonal belt portion and a lap belt portion, each of which is connected to a seatbelt retractor that can be fixedly secured to the vehicle, a seatbelt buckle that can de fixedly secured to the vehicle, and a seatbelt tongue that can be locked to the seatbelt buckle. One end of the lap belt portion is secured to the seatbelt tongue, and one end of the diagonal belt portion is secured to a fitting, the fitting being rotatably connected to the seatbelt tongue. At least one sensor is provided and designed to detect the rotational angular position of the fitting with respect to the seatbelt tongue and/or the seatbelt buckle. The invention further relates to a corresponding method.
