Abstract: 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. The first tightening force and the second tightening force acting constantly in the retracting direction.

Abstract: A motor vehicle including a preventive protective system which includes safety devices actuated as a function of information obtained from a vehicle state sensor system and evaluated in a data evaluation and control device. In the associated process, the data evaluation and control device compares the recorded information with at least one triggering threshold value and actuates at least one safety device which is associated with this driving state when a criticality of the driving state is identified. Triggering of the associated safety device is actuated with respect to a force time gradient as a function of the identified criticality of the driving state.

Abstract: The invention relates to a vehicle occupant protection system for a motor vehicle having a vehicle seat with airbags which are integrated into lateral areas of a seating part and of a backrest, the air pressure of the airbags being adjustable by means of a compressed air regulating device. According to the invention, a coordination system is provided which evaluates the data which is relevant to the safety of the driving operation, and times the actuation of the compressed air regulating device in such a way that at least one airbag of the vehicle seat is inflated before the occurrence of an anticipated accident.
