Abstract: A vehicle seat belt retractor with a belt shaft (10) and a coupled profile head lockable to a housing. A force-limiting device has at least two elements (11, 12) between profile head and belt shaft (10). Free ends (15, 16) of the force-limiting elements (11, 12) are coupled to each other by a connecting tube (13) via a coupling element (18). The coupling element (18) has a hook-shaped spring element with a locking hook (19) which slides over the connecting tube (13) when the belt shaft (10) rotates and engages in a locking groove (20) to couple the connecting tube (13) to the belt shaft (10). At a preset angle of rotation of the belt shaft (10) is reached, the bridging device releases the coupling element (18) for the locking hook (19) to latch into the connecting tube locking groove (20).

Abstract: A seatbelt device for a motor vehicle, including: 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 be 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.
