Abstract
A seat belt retractor has a belt reel for seat belt webbing and a load limiter that has a flowable load-limiter medium which is transported through a flow channel, by a displacement device. The displacement device is drivable by the belt reel, at an energy consumption related to a crash, in which the flow resistance of the transported load-limiter medium in the flow channel or the volume of the load-limiter medium transported in the flow channel per unit time is adjustable.
