Description
Die Erfindung betrifft eine Sicherheitsgurteinrichtung nach dem Oberbegriff des Anspruchs 1.The The invention relates to a safety belt device according to the preamble of claim 1.
Ein Sicherheitsgurtsystem in einem modernen Kraftfahrzeug weist zumindest folgende Bestandteile auf: Einen Aufroller, in dem sich drehbar gelagert eine Gurtspule befindet, auf der das Gurtband aufgewickelt ist, eine am Gurtband angeordnete Gurtzunge und ein am Sitz oder am Fahrzeug angeordnetes Gurtschloss, in das die Gurtzunge eingesteckt werden kann. Die Gurtspule ist hierbei von einer Feder derart beaufschlagt, dass das Gurtband automatisch eingezogen wird und sich bei angelegtem Gurt die benötigte Gurtbandlänge stufenlos einstellt.One Seat belt system in a modern motor vehicle has at least following components: A reel, in which rotatably mounted a belt spool is on which the webbing is wound, a Gurtzunge arranged on the strap and on the seat or on the vehicle arranged belt buckle, in which the belt tongue are inserted can. The belt reel is in this case acted upon by a spring, that the webbing is pulled in automatically and when put on Strap the needed webbing infinitely adjustable.
Für manche Anwendungen ist es wichtig zu wissen, wie weit das Gurtband ausgezogen ist. Beispielsweise lassen sich aus dieser Information Rückschlüsse auf die Größe und damit das Gewicht des Insassen ziehen. Diese Information wiederum kann für die Steuerung eines adaptiven Airbagsystems oder eines adaptiven Kraftbegrenzungssystems eines Aufrollers benötigt werden.For some Applications it is important to know how far the webbing pulled out is. For example, conclusions can be drawn from this information the size and with it pull the weight of the occupant. This information in turn can be used for the controller an adaptive airbag system or an adaptive force limiting system a retractor needed become.
Eine
andere Anwendung ergibt sich beispielsweise aus der
Die Bestimmung der Gurtauszugslänge geschieht bei bisherigen Systemen in der Regel dadurch, dass die Umdrehungen der Gurtspule gezählt und diese Informationen in elektrische Signale umgewandelt werden. Diese Lösung ist mechanisch relativ aufwendig und hat insbesondere auch den Nachteil, dass zusätzliche mechanische Teile am Aufroller angeordnet werden müssen, was zusätzlichen Bauraum benötigt, welcher jedoch in der Regel knapp bemessen ist.The Determination of the belt extension length happens in previous systems usually characterized in that the Turns of the belt reel counted and this information is converted into electrical signals. These solution is relatively expensive mechanically and in particular has the disadvantage that additional mechanical parts on the retractor must be arranged, which additional Space required, which, however, is usually tight.

Hiervon ausgehend ist es Aufgabe der Erfindung, eine gattungsgemäße Sicherheitsgurteinrichtung dahingehend weiterzubilden, dass die Herstellung des Gurtbandes vereinfacht wird.Of these, Based on the object of the invention, a generic seat belt device to further develop that the production of the webbing is simplified.
Diese Aufgabe wird durch eine Sicherheitsgurteinrichtung mit den Merkmalen des Anspruchs 1 gelöst.These Task is by a seat belt device with the features of claim 1.
Es
ist bekannt, beispielsweise aus der bereits erwähnten
Grundidee der Erfindung ist es, solche elektrische Leiter, die in manchen Fällen ohnehin vorhanden sind, zur Bestimmung der Gurtauszugslänge zu benutzen. Hierbei wird beispielsweise der Umstand ausgenutzt, dass sich bei Aufwickeln eines Drahtabschnitts dessen Induktivität erhöht. Bei passender Anordnung von wenigstens zwei Drähten am Gurtband kann beim Aufwickeln des Gurtbandes auch eine Erhöhung der Kapazität dieser Anordnung beobachtet werden. Die Änderung der Induktivität oder Kapazität korreliert direkt zur Gurtauszugslänge.The basic idea The invention is to provide such electrical conductors, which in some make anyway, to use to determine the belt extension length. Here, for example, the fact is exploited that at Winding a wire section whose inductance increases. at suitable arrangement of at least two wires on the webbing can during Winding the webbing also increases the capacity of this Arrangement are observed. The change in inductance or capacitance correlates directly to the belt extension length.
Bei Dreipunkt-Gurten ist ein Ende des Gurtbandes an einem zumeist als Ankerplatte bezeichneten Befestigungselement am Fahrzeug oder am Fahrzeugsitz stationär befestigt. Die Ankopplung der elektrischen Leiter ist in diesem Bereich besonders einfach und deshalb in vielen Fällen zu bevorzugen.at Three-point belts is one end of the webbing at one mostly as Anchor plate designated fastener on the vehicle or on the vehicle seat stationary attached. The coupling of the electrical conductors is in this Area particularly simple and therefore in many cases too to prefer.
