ABSTRACT:
A belt winder with a locking toothing and a locking catch provided with at least one locking tooth. The locking catch is able to be moved into the locking toothing in order to lock the belt spool against rotation in a direction of unwinding the safety belt. The belt winder further comprises a control ring rotatable relatively to the belt spool. The control ring is provided with a coupling toothing and engages at the locking catch. The belt winder further comprises a coupling catch rotatably mounted on the belt spool, and a control disc which is non-rotatable relatively to the belt spool and at which an inertial disk is rotatably mounted which on rotation relatively to the control disk brings the coupling catch into engagement with the coupling toothing of the control ring. Thereby, on rotation of the belt spool in the unwinding direction, the control ring is entrained via the coupling catch and the locking catch is engaged into the locking toothing up to a first contact between the locking tooth and the locking toothing. Further, a slot link is provided which couples the locking catch and the control ring such that upon occurrence of the first contact between the locking tooth and the locking toothing, the pivoting movement of the locking catch towards the locking toothing is converted into a rotation of the control ring, which leads the rotation of the belt spool in the unwinding direction.
