Description
Die Erfindung betrifft eine Wagenaufprallsensoranordnung zum Fühlen eines Seitenaufpralls gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to a cart impact sensor assembly for sensing a Side impact according to the preamble of claim 1
Wenn ein Wagen, wie ein Automobil, in einen Unfall verwickelt ist, kann dieser schnell beschleunigt oder abgebremst werden. In solch einer Situation bewegt sich eine im Wagen reisende Person aufgrund ihrer Trägheit mit der ursprünglichen Geschwindigkeit des Wagens weiter und kann daher mit einem Teil des beschleunigenden oder abbremsenden Wagens zusammenstossen. Beispielsweise stoppt der Hauptkörper des Wagens relativ schnell, wenn der Wagen einem frontalen Aufprall ausgesetzt ist, während sich die Person innerhalb des Wa gens weiterhin nach vorne bewegt. Daher wird die in dem Wagen reisende Person nach vorne auf einen feststehenden Teil des Wagens, wie das Lenkrad oder das Armaturenbrett, geworfen. Im Falle eines seitlichen Aufpralls kann jedoch eine nahe der Seite des Aufpralls sitzende Person von in den Fahrraum eindringenden Wagenteilen verletzt werden, bevor die Geschwindigkeit des Hauptkörpers des Wagens sich verändert, d. h. direkt nachdem der Aufprall stattgefunden hat. Diese Seitenaufprallbedingungen benötigen spezielle Sensoranordnungen.If a car, like an automobile, is involved in an accident This can be accelerated or decelerated quickly. In such a Situation moves a person traveling in the car due to their inertia with the original one Speed of the car continues and can therefore with a part Collide the accelerating or decelerating car. For example the main body stops the car relatively quickly when the car a frontal impact is suspended while the person within the car continues to move forward. Therefore, the person traveling in the car will be forward to one fixed part of the car, like the steering wheel or the dashboard, thrown. In the event of a side impact, however, a close person sitting on the side of the impact from penetrating into the driving area Vehicle parts are injured before the speed of the main body of the car Car changes, d. H. immediately after the impact has occurred. These side impact conditions need special sensor arrangements.
Wenn eine Sicherheitseinrichtung in Antwort auf einen seitlichen Aufprall aktiviert werden soll, muss der Sensor, der den Seitenaufprall fühlt, auf diesen antworten können, bevor der innere Teil einer Tür des Wagens einen benachbart zu ihr angeordneten Sitz oder eine auf dem Sitz sitzende Person berührt. Da der komplette Abstand zwischen der äußeren Oberfläche des Wagens und dem Sitz sehr klein ist, muss der Sensor sehr schnell reagieren.If a safety device in response to a lateral impact should be activated, the sensor that feels the side impact on this can answer before the inner part of a door of the car a seat arranged adjacent to it or one on touching the seated person. Because the complete distance between the outer surface of the Car and the seat is very small, the sensor must be very fast react.
Herkömmlicherweise
sind Seitenaufprallsensoren in der Tür eines Wagens angebracht,
selbst wenn die zu aktivierende Sicherheitseinrichtung nicht in
der Tür
plaziert ist. Eine derartige Anordnung eines Seitenaufprallsensors
ist insbesondere aus
Dabei ist jedoch nachteilig, dass das Signal zeitverzögernderweise von dem Sensor auf der Tür zu der Sicherheitseinrichtung übermittelt werden muss, die an der Karosserie des Wagens, die ein Dach, einen Boden, eine Frontwindschutzscheibenfläche, und seitliche Öffnungen für Türen umfasst, angebracht ist. Wird die Übertragungsleitung bei einem Aufprall beschädigt, so ist außerdem ein Aktivieren der Sicherheitseinrichtung nicht mehr gewährleistet.there However, it is disadvantageous that the signal is delayed in time from the sensor on the door too transmitted to the safety device Must be on the body of the car, a roof, a Ground, a front windshield surface, and side openings for doors included, attached is. Will the transmission line damaged in a collision, such is as well activating the safety device is no longer guaranteed.

Anordnung eines Seitenaufprallsensors in einer Tür eines Wagens, wobei die zu
aktivierende Sicherheitseinrichtung ebenfalls in der Tür plaziert ist,

aus der
Der Erfindung liegt daher die Aufgabe zugrunde, die gattungsgemäße Wagenaufprallsensoranordnung zum Fühlen eines Seitenaufpralls derartig weiterzuentwickeln, dass die obengenannten Nachteile des Stands der Technik überwunden werden.Of the Invention is therefore based on the object, the generic car impact sensor assembly to feel a side impact such that the above Disadvantages of the prior art are overcome.
Diese Aufgabe wird durch eine Wagenaufprallsensoranordnung mit den Merkmalen des Patentanspruchs 1 gelöst.These The object is achieved by a carriage impact sensor arrangement with the features of claim 1.
Mit den Patentansprüchen 2 bis 17 werden vorteilhafte Ausführungsformen der Erfindung beansprucht.With the claims 2 to 17 will be advantageous embodiments of the invention claimed.
Weitere Vorteile der Erfindung ergeben sich aus der nachstehenden Beschreibung, in der Ausführungsbeispiele der Erfindung an Hand der schematischen Zeichnung im einzelnen erläutert werden. Dabei zeigt:Further Advantages of the invention will become apparent from the following description, in the embodiments the invention with reference to the schematic drawing will be explained in detail.

Während die Erfindung mit Bezug auf Ausführungsbeispiele dargestellt ist, in welchen zumindest ein Sensor einen ersten Air-Bag aktiviert, der an dem Sitz des Automobils angebracht ist, und wahlweise zusätzlich ein zweiter Air-Bag, der an dem Dach des Automobils angebracht ist, aktiviert wird, kann der Sensor andere Sicherheitsvorrichtungen, wie einen an den B-Pfosten angebrachten Air-Bag oder selbst einen Sicherheitsgurt-Vorspanner triggern. Ausserdem ist vorgesehen, dass, wenn die Türen des Automobils stabil genug sind, die Verstärkungsglieder weggelassen werden können. Der Sensor kann indirekt an der Karosserie des Automobils durch eine dazwischenliegende Trägerplatte oder dergleichen befestigt sein. Jedoch ist der Sensor so anzubringen, dass er im wesentlichen relativ zur Karosserie befestigt ist und somit Deformationen derselben sofort spürt.While the Invention with reference to embodiments is shown, in which at least one sensor a first air bag activated, which is attached to the seat of the automobile, and optionally additionally a second air bag attached to the roof of the automobile, is activated, the sensor can use other safety devices, such as an air bag attached to the B-pillar or even a seatbelt pretensioner trigger. Moreover, it is envisaged that when the doors of the Automotive are stable enough, the reinforcing members are omitted can. The sensor can be indirectly connected to the bodywork of the automobile an intermediate support plate or the like. However, the sensor has to be mounted that it is mounted substantially relative to the body and thus immediately feels their deformation.
