Abstract
A method for retracting a seat belt of a vehicle includes determining an excessive length of seat belt pulled out as the difference between the current length and the minimum length of seat belt pulled out, when the seat belt is in use. The method further includes, if a collision or and/or a risk situation involving the vehicle is detected, retracting the seat belt by applying a retraction force, the retraction force being a function of the excessive length of seat belt pulled out. Further, a safety arrangement of a vehicle includes a seat belt, a first sensor for determining an excessive length of seat belt pulled out, a collision detection system, a retractor for retracting the seat belt by applying the retraction force, and a processor for determining the retraction force as a function of the excessive length of seat belt pulled out.
