Title: Method and device for a safety belt

Abstract: For a safety belt (2) in a vehicle, the belt is tightened in the event of a collision for at least 300 ms, at the same time as the maximum pull on the safety belt is limited to a predetermined value during the whole tightening process. This is made possible by a tightening device (15) being arranged to be able to operate for at least 300 ms and by there being a load-limiting device (14) between the tightening device (15) and the belt.
