ABSTRACT:
A combination of belt retractor and belt pre-tensioner in which the pre-tensioning device is coupled to the belt shaft by means of the vehicle-sensitive or belt strap sensitive locking system of the belt retractor, is characterized in that a lever (16) entrained by the drive wheel (10) on its rotation in the pre-tensioning direction is mounted pivotally on the housing and on its pivoting movement effected by the rotation of the drive wheel (10) its free end (18) comes into engagement with the control disc (12) and in so doing, over part of its pivoting movement, drives the control disc (12) for its relative rotation relatively to the belt shaft and after the lever (16) has passed through its pivoting path serving to drive the control disc (12) it is released from the control disc (12) and the drive wheel (10).
