Description

Mehrschichtiges übernähtes System Multi-layer overstitched system
Die Erfindung betrifft ein mehrschichtiges übernähtes System mit wenigstens zwei voneinander isolierten flächigen elektrischen Leitern.. The invention relates to a multi-layer overstitched system with at least two flat electrical conductors insulated from one another. ,
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 Übemähbereichen liefern.One application for such a system is, for example, a capacitive occupancy detection system integrated in the seat of a motor vehicle. This is built up by two flat conductors made of metallized fabric, which are isolated from each other by a spacing material (e.g. knitted or non-woven). In addition to the insulating property, ensuring a minimum distance between the flat electrical conductors and sufficient fluffiness, the spacer material should often also have great air permeability to ensure climatic comfort of the seat. This leads to the use of sufficiently "open" and soft spacing materials, which, however, do not provide adequate protection against short-circuits in the mowing areas.
Bei derartigen Systemen ist es häufig notwendig, dass textile Sandwichaufbauten, weiche zwei oder mehrere leitfähige Schichten enthalten, miteinander übernäht werden müssen, wie es z.B. bei im Sitz eines Kraftfahrzeuges integrierten FDS- (Field-Detection-Sensor)-Matteπ 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.In systems of this type, it is often necessary for textile sandwich structures which contain two or more conductive layers to be sewn together, as is the case, for example, with FDS (field detection sensor) mats integrated in the seat of a motor vehicle. The problem arises that such sandwich structures can only be sewn over in areas which do not have conductive layers lying one above the other in order to avoid short circuits between the conductive materials due to the sewing process. In large-scale multi-layered 'systems, it is often necessary to sew the multilayer system not only in the edge region without conductive layers, but also in other areas. As a result, the flat electrical conductors form separate areas in the multilayer system. must be electrically connected to each other by cable bridges. The disadvantage here is that the flat electrical Conductors must be placed particularly carefully in their separate areas and must be electrically connected to one another after the sewing work using complex and error-prone contacts.
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.The invention has for its object to provide a multi-layer overstitched system with several superimposed and insulated from each other flat electrical conductors available, the manufacture of which is simple and largely avoids the risk of short circuits between the conductive materials due to the sewing process becomes.
Zur Lösung dieser Aufgabe wird ein mehrschichtiges System vorgeschlagen, in dem wenigstens in einem Ubernähbereich zwischen den voneinander isolierten flächigen elektrischen Leitern eine Übemähschutzschicht aus einem elastischen Material angeordnet ist, die bei Übemähen einen Kurzschluss zwischen den flächigen elektrischen Leitern verhindert.To achieve this object, a multi-layer system is proposed, in which an overmower protection layer made of an elastic material is arranged at least in a sewing area between the mutually insulated flat electrical conductors, which prevents a short circuit between the flat electrical conductors during mowing.
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 Übemähschutzschicht kann neben der Sicherstellung der Übemähbarkeit zusätzlich als elektrische Isolations- und/oder Abstandsschicht wirken.Such a multi-layer, over-sewn system makes it possible to change from a complex manufacture of the system from several smaller systems with their subsequent contacting to a simpler manufacture of the system of any given size in one piece. The mowing protection layer according to the invention can, in addition to ensuring the mowing ability, also act as an electrical insulation and / or spacing layer.
In den abhängigen Ansprüchen 2 bis 11 sind bevorzugte Ausgestaltungen des erfindungsgemäßen mehrschichtigen Systems angegeben.In the dependent claims 2 to 11, preferred configurations of the multilayer system according to the invention are specified.
Im folgenden werden drei Ausführungsbeispiele des erfindungsgemäßen mehrschichtigen übernähten Systems näher erläutert. Es zeigen:In the following, three exemplary embodiments of the multilayer overstitched system according to the invention are explained in more detail. Show it:
Fig. 1 - einen Querschnitt durch eine mehrschichtiges System mit zwei flächigen elektrischen Leitern, wobei die Schichten voneinander beabstandet dargestellt sind; Fig. 2 - eine Draufsicht auf ein mehrschichtiges System mit einer durchgehenden Übemähschutzschicht; und1 shows a cross section through a multi-layer system with two flat electrical conductors, the layers being shown spaced apart from one another; Fig. 2 is a top view of a multi-layer system with a continuous protective layer; and
Fig. 3 - eine Draufsicht auf ein mehrschichtiges System mit einer stellenweise angeordneten Übemähschutzschicht.Fig. 3 - a plan view of a multi-layer system with an over-mowing protective layer arranged in places.
Fig. 1 zeigt einen Querschnitt einer bevorzugten Ausführungsform eines mehrschichtigen Systems 10, wobei die einzelnen Schichten voneinander beabstandet dargestellt sind. Die unterste Schicht des Systems bildet ein Trägermaterial 2, das aus einem elektrisch nicht leitenden, elastischen, glatten, zugbelastbaren und knickfesteπ Material besteht, z.B. aus Gewirke, Charmeuse oder Vlies.1 shows a cross section of a preferred embodiment of a multilayer system 10, the individual layers being shown spaced apart from one another. The bottom layer of the system forms a carrier material 2, which consists of an electrically non-conductive, elastic, smooth, tensile and kink-resistant material, e.g. knitted, charmeuse or fleece.
Auf dem Trägervlies 2 ist ein flächiger elektrischer Leiter 3, der aus einem leitfähigen Gewebe, beispielsweise aus silberbeschichteten Nylon Gewirke, besteht. Auf dem elektrischen Leiter 3 befindet sich ein Abstandsmaterial 5, das z.B. aus Vlies oder Gewirke besteht und eine vorgegebene Dicke aufweist.On the carrier fleece 2 there is a flat electrical conductor 3, which consists of a conductive fabric, for example of silver-coated nylon knitted fabric. On the electrical conductor 3 there is a spacer material 5 which e.g. consists of fleece or knitted fabric and has a predetermined thickness.
Über dem Abstandsmaterial 5 ist eine Übemähschutzschicht 4 angebracht, die aus Silikonkautschuk besteht. Die Übemährschutzschicht 4 kann auch aus anderen Elastomeren, aus Gummi, Silikon, Polymer-Gel und/oder Polymer-Schaum oder aus Leder bestehen. Das Material der Übemähschutzschicht 4 sorgt dafür, dass durch eine Nähnadel oder durch einen Nähfaden während des Nähprozesses mitgezogene oder herausgerissene ieitfähige Faserstücke aus dem unterhalb oder oberhalb dieser Schicht angeordneten leitfähigem Gewebe des Leiters 3 bzw. 3' abgestreift werden. Wesentlich dabei ist, dass das Material der Übemähschutzschicht 4 eine Elastizität aufweist, die gewährleistet, dass sich das Material beim Durchstechen um die Nadel schmiegt und so das Durchziehen von Materialfragrhenten des leitfähigen Gewebes der flächigen elektrischen Leiter 3 und 3' verhindert. Die Übemähschutzschicht 4 kann folgende Parameter aufweisen: ein Elastizitätsmodul zwischen 200 und 15000 N/mm2, vorzugsweise zwischen 1000 und 5000 N/mm2, eine Dicke zwischen 0,2 und 2 mm, vorzugsweise zwischen 0,5 und 1 ,5 mm, eine Reißfestigkeit zwischen 20 und 500 N/mm, vorzugsweise zwischen 50 und 100 N/mm und/oder einen Gleitreibungskoeffizient in Bezug auf das Material des Leiters (3, 3') zwischen 0,2 und 1 ,0, vorzugsweise zwischen 0,2 und 0,6.Above the spacer material 5, a protective layer 4 is attached, which consists of silicone rubber. The protective layer 4 can also consist of other elastomers, of rubber, silicone, polymer gel and / or polymer foam or of leather. The material of the overmowing protective layer 4 ensures that conductive fiber pieces drawn or torn out during the sewing process by a sewing needle or by a sewing thread are stripped from the conductive fabric of the conductor 3 or 3 ′ arranged below or above this layer. It is essential here that the material of the overmower protection layer 4 has an elasticity which ensures that the material nestles around the needle when it is pierced and thus prevents material fragments of the conductive fabric of the flat electrical conductors 3 and 3 'from being pulled through. The overmower protection layer 4 can have the following parameters: an elastic modulus between 200 and 15000 N / mm 2 , preferably between 1000 and 5000 N / mm 2 , a thickness between 0.2 and 2 mm, preferably between 0.5 and 1.5 mm, a tensile strength between 20 and 500 N / mm, preferably between 50 and 100 N / mm and / or one Sliding friction coefficient with respect to the material of the conductor (3, 3 ') between 0.2 and 1.0, preferably between 0.2 and 0.6.
Der flächige elektrische Leiter 3' oberhalb der Übemähschutzschicht 4 besteht aus dem gleichen Material wie der obere flächige elektrische Leiter 3, kann aber auch aus einem anderen leitfähigem Gewebe aufgebaut sein.The flat electrical conductor 3 'above the overmower protection layer 4 consists of the same material as the upper flat electrical conductor 3, but can also be constructed from a different conductive fabric.
Das mehrschichtige übernähte System wird durch eine Deckschicht 1 oberhalb des flächigen elektrischen Leiters 3' abgeschlossen, wodurch ein ausreichender mechanischer Schutz des leitfähigen Gewebes des Leiters 3' erreicht wird. Das Deckmaterial 1 besteht aus Gewirke. Charmeuse und Vlies können hierzu ebenfalls verwendet werden.The multilayer, overstitched system is closed off by a cover layer 1 above the flat electrical conductor 3 ' , as a result of which adequate mechanical protection of the conductive fabric of the conductor 3' is achieved. The cover material 1 consists of knitted fabrics. Charmeuse and fleece can also be used for this.
Das in Fig. 1 dargestellte mehrschichtige System kann auch ohne das Abstandsmaterial 5 zusammengesetzt werden, falls die Übemähschutzschicht 4 ausreichende elektrisch isolierende Eigenschaften aufweist.The multilayer system shown in FIG. 1 can also be assembled without the spacer material 5 if the overmold protection layer 4 has sufficient electrically insulating properties.
Fig. 2 zeigt in Draufsicht das mehrschichtige System mit einer streifenförmig ausgeführten Übemähschutzschicht 4, die sich vom linken Randbereich des Systems bis zum rechten Randbereich durchgehend erstreckt. Diese Ausführungsform ist besonders bevorzugt für den Fall, wenn eine gute Luftdurchlässigkeit des mehrschichtigen Systems gefordert ist. In diesem Fall kommt die Übernährschutzschicht 4 nur in dem Ubernähbereich 6 zur Anwendung.2 shows a top view of the multi-layer system with a strip-like overshoot protective layer 4 which extends continuously from the left edge area of the system to the right edge area. This embodiment is particularly preferred in the case when good air permeability of the multilayer system is required. In this case, the protective layer 4 is used only in the sewing area 6.
Fig. 3 zeigt eine weitere Ausführungsform des erfindungsgemäßen mehrschichtigen Systems, dessen Unterschied zu der in Fig. 2 dargestellten Ausführungsform darin besteht, dass der obere flächige Leiter 3' in dem Ubernähbereich 6 bis auf einen kleinen, die elektrische Leitfähigkeit sichernden Bereich ausgespart ist. Die Länge der streifenförmig ausgeführten Übemähschutzschicht 4 ist dementsprechend bis auf die Länge des den ausgesparten flächigen Leiter 3' überquerenden Ubernähbereichs 6 reduziert. Zur Vermeidung von möglichen Kurzschlüssen zwischen den flächigen Leitern 3, 3' ist es vorteilhaft, dass die Länge der Übemähschutzschicht 4 die Länge des den flächigen Leiter 3' überquerenden Ubernähbereichs 6 leicht übersteigt. Alternativ können beide flächigen Leiter 3, 3' in dem Ubernähbereich 6 auf einen schmalen, die elektrische Leitfähigkeit sichernden Bereich ausgespart sein. Diese Ausführungsform erlaubt es, die kritische Ubernähfläche nochmals deutlich zu reduzieren. FIG. 3 shows a further embodiment of the multi-layer system according to the invention, the difference from the embodiment shown in FIG. 2 is that the upper flat conductor 3 'in the sewing area 6 is left out except for a small area which ensures the electrical conductivity. The length of the overmold protection layer 4, which is in the form of a strip, is accordingly reduced to the length of the sewing area 6 crossing the recessed flat conductor 3 '. In order to avoid possible short circuits between the flat conductors 3, 3 ', it is advantageous that the length of the overshoot protective layer 4 slightly exceeds the length of the sewing area 6 crossing the flat conductor 3'. Alternatively, both flat conductors 3, 3 'in the sewing area 6 can be connected to one narrow area that ensures electrical conductivity. This embodiment makes it possible to significantly reduce the critical sewing area again.
