Ein solches System hat jedoch den Nachteil, daß der Seitenairbag nur in der Höhenrichtung der individuellen Position bzw. der Größe des Insassen angepaßt wird. Der direkte Abstand zwischen dem Insassen und dem Seitenairbag bleibt dabei unberücksichtigt. Beim Unterschreiten eines vorgegebenen Mindest- bzw. Sicherheitsabstandes zwischen dem Insassen und dem Seitenairbag, kann es im Falle eines Unfalls zu Verletzungen kommen, wenn die Wandung des sich entfaltenden Seitenairbags auf Körperteile des Insassen trifft.One However, such system has the disadvantage that the side airbag only in the height direction the individual position or the size of the occupant is adjusted. The direct distance between the occupant and the side airbag remains disregarded. When falling below a specified minimum or safety distance between the occupant and the side airbag, it can in the case of a Accident injuries occur when the wall of the unfolding Side airbags on body parts of the occupant.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Rückhaltesystem für einen Insassen nach dem Oberbegriff des Patentanspruches 1 zu schaffen, welches relativ einfach aufgebaut ist und die genannten Nachteile nicht mehr aufweist. Dabei soll zur Erhöhung des Schutzes für den Insassen die real vorherrschende Insassenposition genauer ermittelt werden.Of the Invention is therefore the object of a restraint system for one To provide occupants according to the preamble of claim 1, which is relatively simple and the disadvantages mentioned no longer has. It is intended to increase the protection for the occupant determine the real prevailing occupant position more accurately.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.These The object is achieved by the Characteristics of claim 1 solved. Advantageous developments The invention are the subject of the dependent claims.
Mit dieser Ausbildung, bei welcher der vor einem Fahrzeuginsassen im Bereich der Armaturentafel angeordnete Airbag etwa in Fahrzeuglängsrichtung verstellbar ausgebildet ist, wird eine im Vergleich mit dem bekannten Stand der Technik höhere Sicherheit erreicht, da in Abhängigkeit von der individuellen Position des Insassen der Airbag motorisch derart verstellt wird, daß zwischen dem Airbag und dem Insassen ständig der vorgegebene Mindest- bzw. Sicherheitsabstand eingehalten wird. Im Falle eines Unfalls wird somit ein optimaler Schutz für den Insassen erreicht, ohne daß durch den sich entfaltenden Airbag eine Gefahr für den Insassen entsteht.With this training, in which the front of a vehicle occupants in Area of the instrument panel arranged airbag approximately in the vehicle longitudinal direction is designed adjustable, one in comparison with the known State of the art higher security achieved, depending on from the individual position of the occupant of the airbag so motor it is adjusted that between the airbag and the occupant constantly the specified minimum or safety distance is maintained. In the case of an accident, thus, an optimal protection for the occupant achieved without by the unfolding airbag creates a danger to the occupant.
Zur Ermittlung der individuellen Positionen des Insassen weist die Sensorik zumindest einen Sensor auf, der in der Lage ist, die Positionen der einzelnen Körperteile des Insassen und/oder des Sitzes, auf dem der Insasse sitzt, aufzunehmen. Ein solcher Sensor kann beispielsweise durch einen Ultraschallgeber und -empfänger gebildet sein, der mit unsichtbaren Strahlen die Kontur des Insassen abtastet und Informationen bzw. Signale zur Auswertung und Steuerung einer den Airbag verstellenden Antriebseinrichtung abgibt. Durch einen solchen Sensor kann insbesondere die Lage des Kopfes und des Brustkörpers des Insassen detektiert werden, wobei die Detektierung des Brustkörpers auch an einer strahlenreflektierenden Stelle des Sicher heitsgurtes erfolgen kann.to Determining the individual positions of the occupant assigns the sensors at least one sensor that is capable of positions of the individual body parts of the occupant and / or seat on which the occupant sits. Such a sensor can for example by an ultrasonic generator and receiver be formed, with invisible rays the contour of the occupant scans and information or signals for evaluation and control a dispensing the airbag drive device emits. By Such a sensor can in particular the position of the head and the breast body the occupant are detected, wherein the detection of the chest body also can be done on a radiopaque body of the safety belt.
Gemäß einer bevorzugten Ausführung der Erfindung ist der Airbag in einem Gehäuse untergebracht, das an einem Querträger der Armaturentafel etwa in der Fahrzeuglängsrichtung verstellbar und in der jeweiligen verstellten Position unverschiebbar bzw. verriegelbar gelagert ist. Dazu ist eine mit dem Querträger verbundene schienenartige Führung vorgesehen, die das mit der Antriebseinrichtung in Verbindung stehende Gehäuse verschiebbar aufnimmt. Diese Antriebseinrichtung kann in einer ersten Ausführungsform beispielsweise einen Elektromotor aufweisen, der eine an sich bekannte Gewindewelle antreibt, die in einer Gewindebohrung des Gehäuses geführt ist. Zum Vermeiden einer ungewollten Verschiebung des Gehäuses entlang der schienenartigen Führung bei der Entfaltung des Airbags ist bei dieser Ausführung die Steigung des Gewindes der Gewindewelle selbsthemmend ausgebildet.According to a preferred embodiment of the invention, the airbag is housed in a housing which is mounted on a cross member of the dashboard approximately in the vehicle longitudinal direction adjustable and immovable or locked in the respective adjusted position. For this purpose, a rail-like guide connected to the cross member is provided, which accommodates the housing connected to the drive device in a displaceable manner. In a first embodiment, this drive device may, for example, have an electric motor which drives a threaded shaft known per se, which in a threaded bore of the housing is guided. To avoid an unwanted displacement of the housing along the rail-like guide in the deployment of the airbag, the pitch of the thread of the threaded shaft is self-locking in this embodiment.
Anstelle der Gewindewelle kann auch ein vom Elektromotor angetriebenes Schneckenrad vorgesehen sein, das mit einer am Gehäuse oder an einem dieses tragenden Schlitten vorgesehenen Zahnleiste im Eingriff steht. Bei dieser in der Art eines Schneckengetriebes ausgebildeten Kraftübertragung ist ebenfalls eine Selbsthemmung bei stehendem Schneckenrad vorgesehen.Instead of the threaded shaft can also be driven by the electric motor worm wheel Be provided with a on the housing or on this one bearing Carriage provided rack is engaged. At this is in the form of a worm gear trained power transmission also provided a self-locking with the worm wheel.
Gemäß einer weiteren Ausführungsform der Erfindung kann die Sicherheit des Insassen bei einem Unfall dadurch erhöht werden, daß eine auf pyrotechnischer Basis arbeitende Antriebseinrichtung unmittelbar vor der Entfaltung des Airbags in Aktion tritt und den Airbag in eine vorgegebene, aber vom Insassen am weitesten entfernte Position verstellt. Dadurch kann beispielsweise die Gefahr einer Verletzung im Falle, wenn sich der Insasse zum Zeitpunkt des Unfalls nicht in seiner üblichen Position befindet, vermieden oder erheblich reduziert werden. Denn je näher der Insasse sich am gefalteten Airbag befindet, desto größer ist die Wahrscheinlichkeit, daß er von Wandungsteilen des Airbags getroffen wird. Durch die rechtzeitige Verstellung des Airbags in Richtung weg vom Insassen wird diese Wahrscheinlichkeit wesentlich reduziert.According to one another embodiment The invention can improve the safety of the occupant in the event of an accident thereby increased be that one on pyrotechnic basis operating drive device immediately before the deployment of the airbag comes into action and the airbag in a predetermined but farthest from the occupant position adjusted. This can, for example, the risk of injury in case if the inmate is not at the time of the accident in his usual Position is located, avoided or significantly reduced. Because the nearer the occupant is at the folded airbag, the larger the probability that he is hit by wall parts of the airbag. By the timely Adjustment of the airbag in the direction away from the occupant becomes this Probability significantly reduced.
