Abstract: A belt retractor having an electrically actuatable locking device comprising a housing with a base plate and an upright first limb, a locking lever mounted pivotably on the upright first limb with a steel plate which is spring-loaded, and an electromagnet arranged in the housing and having a coil with a through opening, a first iron core which is arranged in the through opening, when a voltage is applied to the coil, exerts a magnetic force on the locking lever via the steel plate and actuates the locking lever for triggering a locking or unlocking movement against the force of the spring. The movement of the locking lever is enforced by a first magnetic circuit formed by the first iron core, the upright first limb and the portions of the base plate and of the locking lever between the first iron core and the upright first limb.

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 load-bearing seatbelt retractor for a seat structure of a vehicle seat, the seatbelt retractor having two housing halves between which functional modules of the seatbelt retractor are disposed. One functional module is a belt reel having a winding axis. The two housing halves form two mutually parallel receptacles in the seatbelt retractor, which are oriented perpendicular to the winding axis. Two seat bars can be inserted into the receptacles. The two housing halves are in contact at least on two contact lines above and below the functional modules with respect to an insertion direction of the receptacles. The lower contact line splits open on both sides along the winding axis such that respective intermediate spaces open toward the receptacles are formed.
