Abstract
Ausrüstungsteil von Fahrzeugen mit einem die Außenkontur beeinflussenden volumenveränderlichen Behälter, der mit einer variablen Füllmenge eines Füllmediums beaufschlagbar ist, und der Behälter an seiner Wand zwei einander gegenüberliegende Flächen (2, 3) besitzt, deren gegenseitiger Abstand entsprechend der Befüllung veränderlich ist, dadurch gekennzeichnet, dass die Flächen elektrisch leitend und Bestandteil eines elektrischen Kondensators sind und der Abstand der beiden Flächen hierdurch bestimmbar ist.piece of equipment of vehicles with a the outer contour influencing variable volumes Container, the one with a variable capacity a filling medium is acted upon, and the container on its wall two opposing surfaces (2, 3) whose mutual distance varies according to the filling is, characterized in that the surfaces are electrically conductive and Part of an electrical capacitor are and the distance of the two surfaces This is determinable.
Description
Die Erfindung bezieht sich auf ein Ausrüstungsteil von Fahrzeugen mit einem die Außenkontur beeinflussenden volumenveränderlichen Behälter, der mit einer variablen Füllmenge eines Füllmediums beaufschlagbar ist, gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a piece of equipment of vehicles a the outer contour influencing variable volume Container, the with a variable capacity a fill medium acted upon is, according to the generic term of claim 1.
Derartige Behälter werden beispielsweise bei Fahrzeugsitzen eingesetzt und dienen dazu, die Form des Fahrzeugsitzes an die Bedürfnisse des Fahrgastes anzupassen und beispielsweise den Sitzkomfort zu fördern. Es ist damit möglich, die Außenkontur an die Größe des Fahrgastes anzupassen, um so unabhängig von der Größe jedem Fahrgast den optimalen Sitz zur Verfügung zu stellen. Hierfür sind an verschiedenen Stellen des Sitzes derartige Behälter für Luft oder eine inkompressible Flüssigkeit als Füllmedium angeordnet, die im Bedarfsfall unterschiedlich stark befällt werden. Es ist damit sogar möglich, der Ermüdung des Fahrgastes entgegenzuwirken, indem die Behälter während der Fahrt in ihrem Volumen variiert wird. Einflußgrößen für die Steuerung der Befüllung können somit die Körpergröße des Fahrgastes, die Fahrtdauer, gegebenenfalls der Verlauf der Fahrbahn (zur einseitigen Verstärkung des Sitzes bei einer Kurvenfahrt) oder aber auch der Ermüdungszustand des Fahrgastes sein.such container are used for example in vehicle seats and serve adapt the shape of the vehicle seat to the needs of the passenger and, for example, to promote seating comfort. It is thus possible, the outer contour to the size of the passenger adapt so independently of the size of each Passenger to provide the optimum fit. For this purpose are on various places of the seat such containers for air or incompressible liquid as a filling medium arranged, which are differently affected if necessary. It is even possible fatigue counteract the passenger by the containers while driving in their volume is varied. Influencing variables for the control the filling can thus the height of the passenger, the duration of the journey, if necessary the course of the road (to the one-sided reinforcement the seat when cornering) or the fatigue state be the passenger.
Wesentlich bei sämtlichen Anwendungsfällen ist die exakte Kenntnis des tatsächlichen Volumens des Behälters und damit des Verlaufs der Außenkontur des Ausrüstungsteils. Es ist in diesem Zusammenhang bekannt, den Luftdruck als Maß hierfür zu verwenden. Da der Luftdruck temperaturabhängig ist und auch aufgrund von Bewegungen und dem Gewicht des Fahrgastes in seiner Größe schwankt, ist der Parameter Luftdruck ein völlig unzureichender Indikator für die Bestimmung der Außenkontur des Ausrüstungsteils.Essential in all applications is the exact knowledge of the actual Volume of the container and thus the course of the outer contour of the piece of equipment. It is known in this context to use the air pressure as a measure of this. Since the air pressure is temperature dependent and also due to movements and the weight of the passenger varies in size, the parameter air pressure is a completely insufficient indicator for the Determination of the outer contour of the piece of equipment.

Der Erfindung liegt die Aufgabe zugrunde, ein Ausrüstungsteil der eingangs genannten Art zu schaffen, mit dem eine exakte Bestimmung der Außenkontur des Ausrüstungsteils möglich ist.Of the Invention is based on the object, a piece of equipment of the aforementioned To create a kind, with which an exact determination of the outer contour of the piece of equipment possible is.
Die Erfindung löst diese Aufgabe durch die Merkmale des Patentanspruchs 1.The Invention solves This object is achieved by the features of patent claim 1.
Es wird nunmehr die Außenkontur des Ausrüstungsteils bzw. die Größe des Volumens nicht indirekt, sondern direkt über den Abstand der beiden Flächen bestimmt. Dieser Abstand korreliert eindeutig mit der Außenkontur des Ausrüstungsteils und verändert sich entsprechend. Damit ist es auf einfache Weise möglich, die Außenkontur eindeutig zu bestimmen.It now becomes the outer contour of the piece of equipment or the size of the volume not indirectly, but directly over the distance between the two surfaces certainly. This distance clearly correlates with the outer contour of the piece of equipment and changed accordingly. This makes it possible in a simple way, the outer contour to be clearly determined.
Die Bestimmung des Abstands der beiden Flächen kann beispielsweise optisch nach Art eines Triangulationsverfahrens vorgenommen werden, was nicht Gegenstand des Patentanspruchs 1 ist. Demgegenüber ergibt sich erfindungsgemäß eine Vereinfachung, wenn die Flächen elektrisch leitend und Bestandteil eines elektrischen Kondensators sind. Die Kapazität des Kondensators korreliert eindeutig mit dem Abstand der beiden Flächen. Damit ist es möglich, die Bestimmung der mechanischen Größe Weg elektrisch durch Bestimmung der Kapazität eines Kondensators vorzunehmen. Diese Bestimmung kann beispielsweise mit Hilfe eines Schwingkreises erfolgen, dessen einer Bestandteil der Kondensator ist und dessen Resonanzfrequenz von dieser Kapazität abhängt. Durch Bestimmung der Resonanzfrequenz des Schwingkreises ergibt sich damit eine eindeutige Aussage über die Außenkontur des Ausrüstungsteils.The Determining the distance of the two surfaces can, for example, optically be done in the manner of a triangulation method, which is not the subject of claim 1. In contrast, results according to the invention, a simplification, if the surfaces are electrically conductive and part of an electrical capacitor. The capacity of the capacitor clearly correlates with the distance between the two Surfaces. This makes it possible the determination of the mechanical size way electrically by determination the capacity of one Make condenser. This provision can be used, for example, with Help a resonant circuit made, one of the components of the Capacitor is and its resonant frequency depends on this capacity. By Determination of the resonant frequency of the resonant circuit thus results in a clear statement about the outer contour of the piece of equipment.
Anhand der Zeichnung ist die Erfindung weiter erläutert.Based the drawing, the invention is further explained.
