Abstract
A belt retractor has a frame (,), a belt reel rotatably mounted about an axis in the frame, a control disc (,) coaxial with the belt reel and a reduction gear unit (,) which translates rotation the belt reel into a reduced rotation of the control disc. The control disc has a cutout window (,) between a pair of detector elements. The first (,) of these detector elements is connected to the belt reel for joint rotation and the second (,) is arranged as fixed relative to the frame. The window is located on the same radius as said detector elements relative to the axis. The arrangement provides a precise measurement of the absolute angle of rotation of the belt reel.
