Two coupling pawls are mounted eccentrically and pivotably in their center of gravity on a drive pulley of the tightening rotary drive. A coupling ring is non-rotatably connected to the belt coiling shaft of the belt retractor. The coupling ring comprises an internal toothing into which the coupling pawls are driven solely by the action of inertia forces to establish a coupling connection. The coupling pawls are offset in the peripheral direction with respect to each other by an angle which corresponds to an odd multiple of half the pitch of the internal toothing of the coupling ring. |
