Abstract: The invention relates to a belt retractor for a safety belt, having: a belt reel (100, 200, 300, 400, 500, 600) for winding up the safety belt; a locking base (120, 220, 320, 420, 520, 620) which during normal operation is conjointly rotated with the belt reel and the rotary motion of which upon abrupt belt extraction is locked by means of a locking mechanism; and a belt force limiting installation which upon locking of the locking base permits relative rotation between the belt reel and the locking base.It is provided according to the invention that the belt retractor has a deactivation installation which after a predefined maximum relative rotary angle between the locking base and the belt reel blocks the relative rotation which is permitted between the belt reel and the locking base by the belt force limiting installation and, on account thereof, deactivates the belt force limiting installation.
