Abstract

A belt retractor has a frame (10), a belt spool (12) that is rotatably mounted in the frame (10), and a force limiter (22) that is adapted to reach a force limiting position. A guide-in mechanism (26) is provided which causes the force limiter (22) to reach the force limiting position as a function of the length of belt webbing withdrawn.
