Description

Die Erfindung betrifft ein Kraftfahrzeug mit einem Sicherheitssitz und einer Unfallerkennungsvorrichtung.The invention relates to a motor vehicle with a safety seat and an accident detection device.

Aus der US 5 810 417 A ist ein Sicherheitssitz für Fahrzeuge bekannt, dessen Rückenlehne bei einer frontalen Kollision des Fahrzeugs nach rückwärts neigbar ist. Der Oberkörper des auf dem Sicherheitssitz befindlichen Fahrzeuginsassen ist derart an die Rückenlehne fixierbar, dass sich der Oberkörper zusammen mit der Rückenlehne bei der Kollision mit der Rückenlehne nach hinten bewegt.From the US 5,810,417 A is known a safety seat for vehicles, the backrest is tilted backwards in a frontal collision of the vehicle. The upper body of the vehicle occupant seated on the safety seat can be fixed to the backrest in such a way that the upper body, together with the backrest, moves backwards in the collision with the backrest.

Üblicherweise sind Sicherheitssitze in Kraftfahrzeugen zu jedem Zeitpunkt räumlich fixiert. Auch bei einer Kollision des Kraftfahrzeugs mit einem Objekt verbleiben deshalb solche Sicherheitssitze relativ zum Kraftfahrzeug stationär. Insbesondere im Falle eines schweren frontalen Zusammenstoßes des Kraftfahrzeugs mit einhergehender schwerer Deformierung des Kraftfahrzeugs können solch räumlich fixierte Sicherheitssitze die Bergung von Kraftfahrzeuginsassen erschweren.Usually safety seats in motor vehicles are spatially fixed at any time. Even with a collision of the motor vehicle with an object, therefore, such safety seats remain stationary relative to the motor vehicle. In particular, in the case of a severe frontal collision of the motor vehicle with concomitant severe deformation of the motor vehicle such spatially fixed safety seats can make the recovery of motor vehicle occupants difficult.

Der Erfindung liegt daher die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Kraftfahrzeug der eingangs genannten Art zu entwickeln, das eine Bauart bedingte verbesserte Bergung der Kraftfahrzeuginsassen ermöglicht.The invention is therefore based on the object to develop a comparison with the prior art improved motor vehicle of the type mentioned, which allows a type conditional recovery of the vehicle occupants.

Die Aufgabe wird erfindungsgemäß durch ein Kraftfahrzeug der eingangs genannten Art mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.The object is achieved by a motor vehicle of the type mentioned above with the characterizing features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Bei einem Kraftfahrzeug mit einem Sicherheitssitz und einer Unfallerkennungsvorrichtung ist der Sicherheitssitz im Falle einer erkannten Kollision des Kraftfahrzeugs mit einem Objekt in den rückwärtigen Kraftfahrzeuginnenraum bewegbar. Dadurch ist sichergestellt, dass insbesondere der Kraftfahrzeugführer auch bei einem schweren frontalen Unfall aus dem besonders kritischen Bereich des Lenkrads und der Steuerungspedale befreit werden kann. Das erfindungsgemäße Kraftfahrzeug verfügt somit über eine Bauart bedingte verbesserte Bergungsmöglichkeit des Kraftfahrzeuginsassen.In a motor vehicle with a safety seat and an accident detection device, the safety seat is movable in the event of a detected collision of the motor vehicle with an object in the rear of the vehicle interior. This ensures that in particular the motor vehicle driver can be freed from the particularly critical region of the steering wheel and the control pedals even in the event of a serious frontal accident. The motor vehicle according to the invention thus has a design-related improved recovery option of the motor vehicle occupant.

In einer besonders bevorzugten Ausführung der Erfindung ist die Strecke, wie weit der Sicherheitssitz in den rückwärtigen Kraftfahrzeugraum bewegbar ist, durch eine Erkennungsvorrichtung zur Sitzplatzbelegung begrenzbar. Somit ist insbesondere verhinderbar, dass ein hinter dem bewegbaren Sicherheitssitz sitzender Kraftfahrzeuginsasse durch das Zurückfahren des Sicherheitssitzes im Falle eines Unfalls eingeklemmt ist. Auch ein unnötiges Zurückfahren eines unbelegten Sicherheitssitzes ist durch eine Erkennungsvorrichtung zur Sitzplatzbelegung vermeidbar.In a particularly preferred embodiment of the invention, the distance how far the safety seat can be moved into the rear vehicle compartment can be limited by a recognition device for seat occupancy. Thus, it can be prevented, in particular, that a motor vehicle occupant sitting behind the movable safety seat is trapped by the return of the safety seat in the event of an accident. Even an unnecessary return of an unoccupied safety seat can be avoided by a recognition device for seat occupancy.

Ein Ausführungsbeispiel der Erfindung wird anhand einer Zeichnung näher erläutert.An embodiment of the invention will be explained in more detail with reference to a drawing.

Dabei zeigt:Showing:

1 schematisch eine Draufsicht des erfindungsgemäßen Kraftfahrzeugs mit Sicherheitssitz und Unfallerkennungsvorrichtung. 1 schematically a plan view of the motor vehicle according to the invention with safety seat and accident detection device.

1 zeigt ein mögliches Ausführungsbeispiel des erfindungsgemäßen Kraftfahrzeugs mit Sicherheitssitz und Unfallerkennungsvorrichtung als Draufsicht. 1 shows a possible embodiment of the motor vehicle according to the invention with safety seat and accident detection device as a plan view.

Das Kraftfahrzeug 1 ist mit einem im Kraftfahrzeuginnenraum 2 befindlichen Sicherheitssitz 3 ausgestattet. Dieser ist an der Position 3.1 im Kraftfahrzeuginnenraum 2 zu jedem Zeitpunkt räumlich fixiert, falls keine Kollision von der Unfallerkennungsvorrichtung erkannt ist.The car 1 is with a in the vehicle interior 2 located safety seat 3 fitted. This one is at the position 3.1 in the motor vehicle interior 2 spatially fixed at any time, if no collision is detected by the accident detection device.

In einer besonders bevorzugten Ausführung der Erfindung gilt eine Kollision des Kraftfahrzeugs 1 als erkannt, wenn die Steuerung eines vorhandenen Insassenschutzsystems einen Airbag elektronisch zündet. In dieser Ausführung ist somit die Erkennung einer Kollision in besonders einfacher Weise als Abfrage eines entsprechenden elektronischen Signals implementiert.In a particularly preferred embodiment of the invention, a collision of the motor vehicle applies 1 as detected when the controller of an existing occupant protection system ignites an airbag electronically. In this embodiment, the detection of a collision is implemented in a particularly simple manner as a query of a corresponding electronic signal.

Bei einer erkannten Kollision des Kraftfahrzeugs 1 ist die räumliche Fixierung des Sicherheitssitzes 3 im Kraftfahrzeuginnenraum 2 aufhebbar. Der Sicherheitssitz 3 ist dann in den rückwärtigen Kraftfahrzeuginnenraum 2 bewegbar. Beispielsweise kann die räumliche Arretierung des Sicherheitssitzes 3 im Kraftfahrzeug durch ein entsprechendes elektronisches Signal der Steuerung des Insassenschutzsystems an eine Verankerungsvorrichtung des Sicherheitssitzes 3 aufhebbar sein. Der Sicherheitssitz 3 kann dann im Falle eines Unfalls durch einen Bewegungsmechanismus bis zur Position 3.3 zurückgefahren werden.In a detected collision of the motor vehicle 1 is the spatial fixation of the safety seat 3 in the motor vehicle interior 2 canceled. The safety seat 3 is then in the rear vehicle interior 2 movable. For example, the spatial locking of the safety seat 3 in the motor vehicle by a corresponding electronic signal of the control of the occupant protection system to an anchoring device of the safety seat 3 be repealed. The safety seat 3 can then in the event of an accident by a movement mechanism to the position 3.3 be reduced.

In einer weiteren bevorzugten Ausführungsform der Erfindung ist das Kraftfahrzeug mit einer Erkennungsvorrichtung zur Sitzplatzbelegung ausgestattet. Die Belegung eines Sitzplatzes kann beispielsweise durch eine entsprechende, an der Sitzunterseite des Sitzplatzes integrierte Sensorvorrichtung erfasst werden. Ist eine Belegung eines Sitzplatzes hinter einem Sicherheitssitz 3 erkannt, wird die Strecke, um die der Sicherheitssitz in den rückwärtigen Fahrzeugraum im Falle einer Unfallerkennung bewegbar ist, begrenzt. Der Sicherheitssitz 3 ist in diesem Falle nur bis zur Position 3.2 zurückfahrbar. Dies kann beispielsweise durch das Auslösen einer entsprechenden Mechanik der Verankerungsvorrichtung des Sicherheitssitzes 3 durch ein elektronisches Signal realisiert sein. So kann verhindert werden, dass ein im rückwärtigen Fahrzeugraum sitzender Fahrzeuginsasse durch einen zurückfahrenden Sicherheitssitz 3 eingeklemmt wird. Auch das unnötige Zurückfahren eines unbelegten Sicherheitssitzes ist durch eine solche Vorrichtung vermeidbar.In a further preferred embodiment of the invention, the motor vehicle is equipped with a recognition device for seat occupancy. The occupancy of a seat can be detected, for example, by a corresponding, integrated on the underside of the seat seat sensor device. Is an occupancy of a seat behind a safety seat 3 Recognized, the track becomes the safety seat in the rearward vehicle compartment in the event of a Accident detection is movable, limited. The safety seat 3 is in this case only up to the position 3.2 moved back. This can be achieved, for example, by triggering a corresponding mechanism of the anchoring device of the safety seat 3 be realized by an electronic signal. Thus, it can be prevented that a vehicle occupant seated in the rear vehicle compartment by a returning safety seat 3 is trapped. Even the unnecessary return of an unoccupied safety seat can be avoided by such a device.
