Wenigstens in einem Übernähbereich zwischen den flächigen elektrischen Leitern 3, 3' ist eine Übernähschutzschicht 4 aus einem elastischen Material angeordnet.

At least in a transfer region between the planar electrical conductors 3, 3 ', a nonsmooth protective layer 4 made of an elastic material is arranged. The material of the over-protective layer 4 is chosen so that it prevents over-sewing a short circuit between the flat electrical conductors 3, 3 '.
Description
Die Erfindung betrifft ein mehrschichtiges übernähtes System mit wenigstens zwei voneinander isolierten flächigen elektrischen Leitern.The The invention relates to a multi-layered over-stitched system with at least two flat sheets isolated from each other electrical conductors.
Eine Anwendung für ein derartiges System ist beispielsweise ein im Sitz eines Kraftfahrzeuges integriertes kapazitives Besetzterkennungssystem. Dieses wird aufgebaut durch zwei aus metallisiertem Gewebe gebildete flächige Leiter, welche durch ein Abstandmaterial (z.B. Gewirke oder Vliese) voneinander isoliert sind. Das Abstandsmaterial soll häufig neben der isolierenden Eigenschaft, der Sicherstellung eines Mindestabstandes zwischen den flächigen elektrischen Leitern und einer ausreichenden Flauschigkeit auch noch zur Gewährleistung eines Klimakomforts des Sitzes eine große Luftdurchlässigkeit besitzen. Dies führt zur Verwendung von hinreichend "offenen" und weichen Abstandsmaterialien, welche aber keinen ausreichenden Schutz vor Kurzschlüssen in Übernähbereichen liefern.A Application for Such a system is, for example, an integrated in the seat of a motor vehicle capacitive busy detection system. This is built by two formed of metallized fabric flat conductor, which by a spacer material (e.g., knitted fabric or nonwoven fabric) is insulated from each other are. The spacer material is often next to the insulating Property, ensuring a minimum distance between the flat electric Ladders and a sufficient fluffiness even to guarantee of a climate comfort of the seat possess a large air permeability. this leads to for the use of sufficiently "open" and soft spacer materials, but which does not provide adequate protection against short circuits in Überähbereichen deliver.
Bei derartigen Systemen ist es häufig notwendig, dass textile Sandwichaufbauten, welche zwei oder mehrere leitfähige Schichten enthalten, miteinander übernäht werden müssen, wie es z.B. bei im Sitz eines Kraftfahrzeuges integrierten FDS-(Field-Detection-Sensor)-Matten der Fall ist. Es entsteht das Problem, dass solche Sandwichaufbauten nur in Bereichen übernäht werden können, die keine übereinanderliegenden leitfähigen Schichten aufweisen, um Kurzschlüsse zwischen den leitfähigen Materialien durch den Nähprozess zu vermeiden. Bei großflächigen mehrschichtigen Systemen ist es oft notwendig, nicht nur im Randbereich ohne leitfähige Schichten, sondern auch in übrigen Bereichen des Mehrschichtsystems zu übernähen. Dadurch bilden die flächigen elektrischen Leiter separate Bereiche in dem mehrschichtigen System, die miteinander durch Kabelbrücken elektrisch leitend verbunden werden müssen. Nachteilig ist hierbei, dass die flächigen elektrischen Leiter in ihren separaten Bereichen besonders sorgfältig platziert werden müssen und nach den Näharbeiten miteinander durch aufwendige und fehleranfällige Kontaktierungen elektrisch verbunden werden müssen.at such systems are common necessary that textile sandwich structures, which two or more conductive Layers contain, must be sewn together with each other, as e.g. at the seat a motor vehicle integrated FDS (Field Detection Sensor) mats the Case is. The problem arises that such sandwich structures to be sewn only in areas can, the no superimposed ones conductive Have layers to short circuits between the conductive Materials through the sewing process to avoid. For large-area multi-layered It is often necessary for systems, not only in the periphery without conductive layers, but also in the rest To sew over areas of the multi-layer system. As a result, the two-dimensional electrical form Conductor separate areas in the multilayer system, passing through each other cable bridges must be electrically connected. The disadvantage here is that the plane especially carefully placed in their separate areas have to be and after the sewing works together by consuming and error-prone contacts electrically need to be connected.
Der Erfindung liegt die Aufgabe zugrunde, ein mehrschichtiges übernähtes System mit mehreren übereinander angeordneten und voneinander isolierten flächigen elektrischen Leitern zur Verfügung zu stellen, dessen Herstellung einfach ist und dabei das Risiko, dass es durch den Nähprozess zu Kurzschlüssen zwischen den leitfähigen Materialien kommt, weitgehend vermieden wird.Of the Invention is based on the object, a multi-layer oversewn system with several on top of each other arranged and insulated from each other flat electrical conductors to disposal whose production is simple and at the same time the risk that it through the sewing process to short circuits between the conductive Materials comes, largely avoided.
Zur Lösung dieser Aufgabe wird ein mehrschichtiges System vorgeschlagen, in dem wenigstens in einem Übernähbereich zwischen den voneinander isolierten flächigen elektrischen Leitern eine Übernähschutzschicht aus einem elastischen Material angeordnet ist, die bei Übernähen einen Kurzschluss zwischen den flächigen elektrischen Leitern verhindert.to solution This object is proposed in a multilayer system, in the at least in a Überähbereich between the flat electrical conductors insulated from each other an overprotective layer is arranged from an elastic material, the overseeking a Short circuit between the two-dimensional prevents electrical conductors.
Ein solches mehrschichtiges übernähtes System erlaubt es, von einer aufwendigen Fertigung des Systems aus mehreren kleineren Systemen mit ihrer anschließenden Kontaktierung miteinander zu einer einfacheren Herstellung des Systems einer beliebigen vorgegebenen Größe in einem Stück überzugehen. Die erfindungsgemäße Übernähschutzschicht kann neben der Sicherstellung der Übernähbarkeit zusätzlich als elektrische Isolations- und/oder Abstandsschicht wirken.One such multi-layered sewed system makes it possible, from a complex production of the system of several smaller systems with their subsequent contacting each other to simplify the production of the system of any given Size in one Move over. The over-protective layer according to the invention In addition to ensuring overseeability in addition to electrical insulation and / or spacer layer act.
