Abstract
An automatic seat belt retractor includes a belt reel configured to wind a seat belt and a sensor configured to permanently record a rotational speed of the belt reel. The sensor cooperates with an element that is speed-coupled to the belt reel to record the rotational speed. The automatic seat belt retractor includes a brake unit configured to decelerate the seat belt being unwound from the belt reel with a restraining force and a control module configured to control the brake unit with respect to the restraining force as a function of the rotational speed.
