A restraint system for a vehicle, includes a rotatable reel, a flexible tether, a first shaft and a conductor member. The flexible tether has a first end coupled to the reel and a second end. The tether is wound upon the rotatable reel and movable in both a winding direction and an unwinding direction. The first shaft is configured to be operably coupled to the rotatable reel, and includes a plurality of magnetic elements affixed thereto. The conductor member has a hollow interior. At least a portion of the first shaft and at least a portion of the plurality of magnetic elements are disposed within the hollow interior. Movement of the tether in the unwinding direction causes relative movement between the plurality of magnets and the conductor member. Eddy currents within the conduct member generate a retarding force on the first shaft.

A vehicle safety restraint arrangement includes a retractable and extractable belt, a belt reel on which the belt is windable, a retraction mechanism adapted to retract the belt from an extracted position, and a belt retraction brake adapted to limit the retraction speed of the belt during retraction of the belt by imparting a braking force to the belt reel during retraction of the belt via inductance. The present disclosure also relates to a method for limiting the retraction speed of a belt arranged on a belt reel.

A belt tightener for a safety belt system in a motor vehicle comprises at least one electric actuator. A decentralized, independent electric energy store designed to store a sufficient amount of electric energy for operating the actuator is dedicated to the belt tightener.
