Zusammenfassung: | In a restraining device for an occupant of a vehicle, having a belt that can be drawn out or retracted by a lockable retractor, and a reversible seat-belt tightener, in the case of an impending but still avoidable first event the reversible seat-belt tightener automatically exerts and maintains a first tightening force on the belt and/or reduces the first tightening force if the first event is no longer impending. In the case of an impending, no longer avoidable second event, automatically exerts a second tightening force on the belt which is greater than the first tightening force.
