Es ist Aufgabe der vorliegenden Erfindung, ein zumindest teilweise transparentes Element für ein Fahrzeugdach zu schaffen, welches zugleich für die Stromversorgung eines elektrischen Verbrauchers ausgebildet ist, auf relativ einfache Weise hergestellt werden kann, eine relativ gute elektrische Leitfähigkeit aufweist und in ästhetischer Hinsicht möglichst ansprechend ausgebildet werden kann. Insbesondere sollen die elektrischen Zuleitungen für den elektrischen Verbraucher für die Fahrzeuginsassen möglichst nicht sichtbar sein. Ferner soll ein entsprechendes Herstellungsverfahren für ein solches Dachelement geschaffen werden.It is an object of the present invention to create at least partially transparent element for a vehicle roof, which at the same time for the Power supply of an electrical consumer is formed, can be produced in a relatively simple manner, a relatively good electrical conductivity has and in aesthetic Respects if possible can be trained appropriately. In particular, the electrical Supply lines for the electrical Consumer for the vehicle occupants if possible not be visible. A corresponding manufacturing process is also intended for a such roof element can be created.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Dachelement gemäß Anspruch 1 sowie ein Herstellungsverfahren gemäß Anspruch 14.According to the invention, this object is achieved by a roof element according to claim 1 and a manufacturing method according to claim 14.
Bei der erfindungsgemäßen Lösung ist vorteilhaft, dass die beiden elektrisch leitenden Schichten aufgrund des Vorsehens einer elektrisch isolierenden Schicht dazwischen flächig ausgebildet sein können, wodurch eine aufwendige und optisch störende Ausbildung von galvanisch getrennten Leiterbahnen nicht erforderlich ist; d.h., dadurch, dass die Schichten übereinander angeordnet sind, kann auf eine laterale Strukturierung verzichtet werden.In the solution according to the invention advantageous that the two electrically conductive layers due of providing an electrically insulating layer between them could be, whereby a complex and optically disruptive formation of galvanic separate conductor tracks is not required; i.e., in that the layers on top of each other are arranged, a lateral structuring can be dispensed with become.
Besonders vorteilhaft ist der erfindungsgemäße Schichtaufbau, wenn es sich bei den elektrisch leitenden Schichten um Metallschichten und bei den elektrisch isolierenden Schichten um Schichten des jeweiligen Metalloxids handelt. In diesem Fall kann sowohl eine hohe elektrische Leitfähigkeit sowie eine einfache Schichtaufbringung erzielt werden.The layer structure according to the invention is particularly advantageous, if the electrically conductive layers are metal layers and with the electrically insulating layers by layers of the respective Metal oxide acts. In this case, both a high electrical conductivity as well as a simple layer application.
Weitere bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further preferred configurations the invention emerge from the subclaims.
Im folgenden wird die Erfindung anhand der beigefügten Zeichnung beispielhaft näher erläutert, welche eine Querschnittansicht eines erfindungsgemäßen Dachelements zeigt.The invention is explained below the attached Drawing closer as an example explains which shows a cross-sectional view of a roof element according to the invention.

Als Material für die Metallschichten kann beispielsweise Titan verwendet werden, wobei die Oxidschichten dann aus Titanoxid bestehen. Als Schichtdicke kann beispielsweise für jede Schicht 25 nm gewählt werden. Damit lässt sich eine Lichttransmission von ca. 12% im sichtbaren Spektralbereich erzielen. Alternativ kann beispielsweise auch Aluminium für die Metallschichten verwendet werden, beispielsweise mit einer Schichtdicke von 20 nm, wobei die Oxidschichten dann aus Aluminiumoxid, beispielsweise mit einer Schichtdicke von 30 nm, bestehen. Mit einem solchen Metall/Metalloxid-Schichtaufbau kann eine Tönung erzielt werden, die als neutrales Grau empfunden wird. Ein weiterer Vorteil der Verwendung von Metallschichten besteht darin, dass diese eine hohe Infrarot-Reflexion bei geringer Absorption im Vergleich beispielsweise zu massegefärbtem Glas zeigen, wodurch eine zu starke Erwärmung des Fahrzeuginnenraums durch Sonneneinstrahlung verhindert werden kann.Can be used as material for the metal layers For example titanium can be used, the oxide layers then consist of titanium oxide. The layer thickness can be, for example, for each layer 25 nm selected become. With that leaves there is a light transmission of approx. 12% in the visible spectral range achieve. Alternatively, aluminum can also be used for the metal layers, for example are used, for example with a layer thickness of 20 nm, the oxide layers then made of aluminum oxide, for example with a layer thickness of 30 nm. With such a metal / metal oxide layer structure can be a tint can be achieved, which is perceived as a neutral gray. Another The advantage of using metal layers is that they are a high infrared reflection in comparison with low absorption for example to mass-colored Show glass, causing excessive warming of the vehicle interior can be prevented by sunlight.
Ferner hat die Verwendung von Metalloxiden in den isolierenden Schichten den Vorteil, dass diese Oxidschichten in der selben Beschichtungsanlage wie die entsprechenden leitenden Metallschichten hergestellt werden können. Wenn es sich bei dem Oxid der Oxidschicht um ein Oxid der entsprechenden Metallschicht handelt, kann somit einerseits die Herstellung besonders effizient gestaltet werden; andererseits ist auch die dabei erzielte Ähnlichkeit der Festköperstruktur der Schichten von Vorteil. Jedoch kann es auch Gründe geben, Oxidschichten zu verwenden, bei denen es sich nicht um ein Oxid der Metallschicht handelt.Furthermore, the use of metal oxides in the insulating layers have the advantage that these oxide layers in the same coating system as the corresponding conductive ones Metal layers can be produced. If it is the oxide the oxide layer is an oxide of the corresponding metal layer, can thus make production particularly efficient become; on the other hand, there is also the similarity the solid structure of layers is an advantage. However, there can be reasons Use oxide layers that are not an oxide the metal layer.
Grundsätzlich kommen neben den beschriebenen Metallen auch andere Metalle mit entsprechender Leitfähigkeit für die leitenden Schichten in Frage, z.B. Silber, Kupfer oder Gold.Basically come in addition to those described Metals also other metals with appropriate conductivity for the conductive layers in question, e.g. Silver, copper or gold.
Die leitenden Schichten müssen aber
nicht notwendigerweise Metallschichten sein, sondern können beispielsweise
auch als leitende Oxidschichten ausgebildet sein. So kann beispielsweise
