Abstract:
A seat belt retractor comprising a frame with a belt reel having an axis of rotation rotatably mounted in the frame, a blocking means for blocking rotation of a blockable part of the belt reel, and a substantially drum-shaped belt webbing carrier on the belt reel, wherein the belt webbing carrier is arranged with a rotor that is in rotary drive connection with the belt webbing carrier, the rotor being mounted eccentrically relative to the belt reel axis, the belt webbing carrier drives a toothed outer rotor and the rotor comprises a toothed inner rotor, wherein chambers filled a free-flowing medium are formed by intermeshing teeth of the outer rotor and the inner rotor and upon rotation of the rotor the volumes of at least two chambers filled with the free-flowing medium are varied, wherein the chambers rotate about the belt reel axis, and the free-flowing medium flows in each case from one chamber diminishing in volume into another chamber increasing in volume.
