Abstract: A vehicle occupant safety system having an airbag prevents an excessive force from acting upon the thorax of an occupant who has fastened the seat belt, in the event of an impact. The vehicle occupant safety system comprises an airbag, a sensor device for sensing at least one situation parameter and a control device for controlling the inflation and/or deflation and/or unfolding and/or positioning of the airbag in dependence of the at least one situation parameter. The unfolding, position or shape of the airbag and/or distribution of pressure within the airbag at the end of the filling phase, is directly or indirectly controlled in a targeted manner by a control device based on the at least one situation parameter. A modification of the shape of the airbag in the thorax region can be obtained in particular by a releasable constriction.

Abstract: The invention relates to restraint system for a passenger of a vehicle who sits on a vehicle seat that can be placed in different positions. Said restraint system comprises an interior that is defined by a housing (1) and at least on gas bag, and at least one triggerable outlet (36-38) which is disposed on the housing (1) and can be closed by means of a closing element (3) that is movable from a closed position into an open position such that an internal pressure in the interior can be adjusted in accordance with passenger load-relevant parameters during an accident.

Abstract: A passenger vehicle restraint system that is capable of being placed in different positions, consisting of an interior defined by a housing and at least one airbag, at least one gas generator for delivering gas to the interior in order to inflate the airbag, at least one controllable outlet provided on the housing which may be closed by a closing element, such that an internal pressure in the interior may be adjusted according to parameters relevant to passenger load during an accident. A restraint system, which is easy to construct and can be manufactured cost-effectively, is provided by an adjustable stop element limiting the opening movement of the closing element, which is coupled to the vehicle seat such that the stop element is displaced according to parameters relevant to passenger load, in order to adjust the outlet cross section defined by the closing element located in its closed position.

Abstract: A safety device is provided for a motor vehicle having a vehicle seat whose seat setting can be adjusted by a seat adjustment drive. A seat control unit evaluates data that is relevant to the safety of a driving mode and actuates the seat adjustment drive with timing. Thereby, movement of the vehicle seat into a seat setting occurs that is optimum for a vehicle occupant in terms of safety technology is initiated before the occurrence of an anticipated accident event. Movement of the vehicle seat into its optimum seat setting in terms of safety technology is carried out successively in individual adjustment steps for the respective components of the vehicle seat in a predefined sequence by the seat control unit.

Abstract: A safety device is provided for a motor vehicle having a driver's seat whose sitting position can be adjusted by a seat adjustment drive, and a steering wheel whose steering wheel position can be adjusted by a steering wheel adjustment drive. A control unit evaluates the data which is relevant for the safety of a driving mode, and actuates the steering wheel adjustment drive with timing such that, before an anticipated accident event occurs, a movement of the steering wheel into an optimum steering wheel position for the driver in terms of safety equipment is initiated as a function of the current sitting position of the driver's seat.

Abstract: A flexible planar structure unit is provided as load-space securing element, the unit being arranged extended in a protective position in the vicinity of the moveable rear-section arrangement in such a way that loads which are located in the load space, or at least a person who is located on a seat arrangement facing counter to the direction of travel in the load space is protected with points of attachment to the vehicle bodywork being provided for securing the planar structure unit in the extended protective position.

Abstract: An occupant-restraining system has a belt force limiter that limits a restraining force exerted on an occupant via a restraining belt by switching from a relatively higher to a relatively lower level of restraining force depending on predefined parameters. The belt-force limiter is activated only after a predetermined forward displacement of the occupant is reached and only after a predefined air bag inflating time, when an excessive crash intensity and an occupant's weight are recognized as being below a predetermined threshold.

Abstract: Inflatable head protector units are located at a unitized passenger compartment in the vicinity of roof frame sections with an energy-absorbent molded part being provided as a head impact protector at the level of each inflatable head protector unit. The molded part is designed as a launch ramp to guide an expanding airbag of the head protector unit into the desired protective position and located so that the molded part remains positioned at least largely dimensionally stably during the expansion of the airbag.
