Seat belt retractor

A seat belt retractor has a belt reel (1) mounted rotatably around a reel axis (4) on a retractor frame (3) and biased by a motive spring (19). A load limiter (11) is non-rotatably connected to a rotatable spool (10) of the belt reel. A rotor (2) can be coupled to the belt reel and/or its load limiter by a coupling (9), wherein the coupling (9) comprises an annular carrier (6) connected non-rotatably to the belt reel (1) and/or the load limiter (11) for guiding coupling elements (7) between a released and an engaged position, the annular carrier (6) is arranged coaxially around a bearing collar (15) provided on the rotor (2) and is supported against axial displacement on the adapter flange (13).
