A belt retractor for a vehicle safety belt comprises a frame and a belt spool ( 1 ) which is rotatably mounted in the frame, and at least one locking toothing ( 2, 3 ) which is connected with the belt spool. A first locking catch ( 5 ) and a second locking catch ( 6 ) are provided, which are supported on the frame and can engage into the at least one locking toothing ( 2, 3 ). The first locking catch ( 5 ) is able to swing about a point of rotation which is arranged such that with the first locking catch ( 5 ) guided into the locking toothing ( 2, 3 ) a virtual line, which passes through a point of contact between the first locking catch ( 5 ) and the locking toothing ( 2, 3 ) and stands perpendicularly on a tooth face in the point of contact, runs between the point of rotation and a rotation axis of the belt spool ( 1 ). The second locking catch ( 6 ) is able to swing about a point of rotation which is arranged such that with the second locking catch ( 6 ) guided into the locking toothing ( 2, 3 ), a virtual line which passes through a point of contact between the second locking catch ( 6 ) and the locking toothing ( 2, 3 ) and stands perpendicularly on a tooth face in the point of contact, runs on the side of the point of rotation facing away from the rotation axis of the belt spool ( 1 ).
