Abstract

A seat belt retractor has a belt reel for the seat belt webbing. A load limiter allows limited extraction of the belt webbing with energy absorption when the belt reel is blocked. The absorption of energy is adjustable as a function of crash-related data and the rotating movement of the belt reel is scanned for this purpose when the extraction of the belt webbing is limited.
