Abstract
Abstract A motor vehicle with a retaining system for the passengers which includes at least one safety belt as well as means for the automatic re-tightening of the safety belt in case of accident danger; the magnitude of the prestress of the safety belt is thereby adjustable by a control system, which is triggered by a sensor with a definite deceleration threshold, as a function of vehicle velocity change per time unit and/or weight of the respectively retained passenger.
