Abstract: A vehicle seat belt system includes a reversible belt tensioner (12) adapted to apply a belt tightening force (F) on several predetermined levels to a belt strap (14) of a seat belt, a control unit (16) for controlling the belt tensioner (12) and a device (18) for detecting the course of a road (S1, S2) ahead of the vehicle and for identifying bends lying ahead of the vehicle. The control unit (16) causes the belt tightening force (F) to be kept on an increased level when in the course of the road a further bend follows a just taken bend within a predetermined distance.

Abstract: The invention relates to a vehicle part adjusting device (10), especially a belt buckle presenter or belt presenter, comprising a first elongated flexible push member (12), a second elongated flexible push member (14) and a connecting and separating means (16) for the push members (12, 14) which is designed so that it detachably connects the push members (12, 14) upon an adjusting movement of the push members (12, 14) in a first longitudinal direction (X1) to form a bending-resistant interconnected part (18) and separates them upon an adjusting movement of the push members (12, 14) in an opposed second longitudinal direction (X2), wherein the push members (12, 14) are connected and separated in a reversible manner.

Abstract: A belt tensioner of a vehicle occupant restraint system, especially a belt buckle tensioner, comprises a coupling member (12) to the vehicle seat belt, a drive unit (18), a flexible tension transmitting means (14) and a deflector (26). The flexible tension transmitting means (14) is connected at least indirectly to the coupling member (12) and is moved via the drive unit (18) in the event of tensioning. The deflector (26) deflects the tension transmitting means (14) in the direction of the coupling member (12). The tension transmitting means (14) is moved along the deflector (26) in the event of tensioning. According to the invention, the drive unit (18) is coupled in terms of drive to the deflector (26) such that the drive unit (18) moves the deflector (26) upon activation and thus displaces the coupling member (12) in the tensioning direction (R).
