Abstract
A belt retractor for a safety belt, having a belt reel for winding or unwinding the safety belt, and a belt force limiting installation which comprises a first and second torsion bar for limiting belt force. The belt retractor has a free-wheeling transmission which operates depending on the rotation angle and which after activation of the belt force limiting installation initially leaves the second torsion bar so as to be inactive, while the first torsion bar for limiting belt force is already being twisted, and the free-wheeling transmission activates the second torsion bar as soon as the free-wheeling transmission has been rotated about a predefined maximum free-wheeling rotation angle.
