Abstract
A belt retractor for a vehicle safety belt has a frame, a belt reel which is rotatably mounted in the frame, a locking mechanism which is adapted to block a rotation of the belt reel in an unwinding direction of the safety belt in a vehicle sensitive and/or seat belt sensitive manner and a pretensioning drive which is adapted to drive the belt reel in a wind up direction of the safety belt and in the unwinding direction. A locking means is provided which prevents a reverse rotation of the belt reel in the unwinding direction, after the pretensioning drive has driven the belt reel in the wind up direction and has thereby pretensioned the safety belt.
