Abstract

Textiles Gebilde, insbesondere Flächengebilde, mit einem Abstandsgestrick (11, 11'), das zumindest einen Schalterbereich (13, 14; 13', 14') aufweist, in dem die beiden einander gegenüberliegenden Oberflächen des Abstandsgestricks zur Ausbildung von Kontaktflächen (15, 16; 17, 18) aus einem elektrisch leitfähigen Garn gestrickt sind und die dazwischen liegenden Polfäden aus einem elektrisch isolierenden Garn, dadurch gekennzeichnet, dass das Abstandsgestrick (11, 11') mit einer thermisch unter Druck verformbaren textilen Basisschicht (12, 12') verbunden ist.Textile structure, in particular flat structures, having a spacer fabric (11, 11 ') which has at least one switch region (13, 14; 13', 14 ') in which the two oppositely lying surfaces of the spacer fabric are used to form contact surfaces (15, 16 17, 18) are knitted from an electrically conductive yarn and the intervening pile threads of an electrically insulating yarn, characterized in that the spacer fabric (11, 11 ') with a thermally under pressure deformable textile base layer (12, 12') is connected is.

Description

Insbesondere für Fahrzeugsitze werden häufig Gestricke eingesetzt, die zumindest teilweise aus elektrisch leitfähigen Garnen hergestellt sind, um beispielsweise eine Sitzheizung realisieren zu können. Es ist auch bereits bekannt, Abstandsgestricke für Sitze einzusetzen, die einen polsternden Effekt erzielen und in die auch Drucksensoren eingestrickt werden können, um beispielsweise feststellen zu können, ob eine Person auf dem Sitz Platz genommen hat oder nicht.In particular for vehicle seats knits are often used, which are at least partially made of electrically conductive yarns, for example, to realize a seat heater can. It is also already known to use spacer knits for seats which achieve a cushioning effect and in which pressure sensors can also be knitted in order, for example, to be able to determine whether or not a person has sat down on the seat.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein textiles Gebilde herzustellen, das den Einsatz von Gestricken insbesondere im Automobilsektor gegenüber den bekannten Anwendungsmöglichkeiten erweitert.The present invention has for its object to produce a textile structure that extends the use of knitted fabrics in particular in the automotive sector over the known applications.

Zur Lösung dieser Aufgabe schlägt die vorliegende Erfindung ein textiles Gebilde, insbesondere Flächengebilde, mit einem Abstandsgestrick vor, das zumindest einen Schalterbereich aufweist, in dem die beiden einander gegenüberliegenden Oberflächen des Abstandsgestricks zur Ausbildung von Kontaktflächen aus einem elektrisch leitfähigen Garn gestrickt sind und die dazwischen liegenden Polfäden aus einem elektrisch isolierenden Garn, und das dadurch gekennzeichnet ist, dass das Abstandsgestrick mit einer thermisch unter Druck verformbaren textilen Basisschicht verbunden ist.To achieve this object, the present invention proposes a textile structure, in particular sheet, with a spacer fabric, which has at least one switch area in which the two opposing surfaces of the Abstandsgestricks are knitted to form contact surfaces of an electrically conductive yarn and the intervening Pile threads of an electrically insulating yarn, and characterized in that the spacer knit is connected to a thermally compressible textile base layer.

Durch das Verbinden des Abstandsgestricks mit einer bleibend thermisch verformbaren textilen Basisschicht können Formteile mit dem Abstandsgestrick hergestellt werden, die mindestens einen integrierten Schalter aufweisen. Solche Formteile können überall im Innenbereich von Räumen oder Fahrzeugen eingesetzt werden, wo Schaltfunktionen benötigt werden. Dabei kann auf mechanische Teile wie Schaltknöpfe zur Auslösung verzichtet werden. Die Schaltfunktion wird einfach durch Ausübung von Druck auf das textile Gebilde im Bereich der Kontaktflächen ausgelöst.By connecting the spacer knitted fabric with a thermally deformable textile base layer, moldings can be produced with the spacer knitted fabric having at least one integrated switch. Such moldings can be used anywhere in the interior of rooms or vehicles where switching functions are needed. It can be dispensed with mechanical parts such as buttons to trigger. The switching function is triggered simply by exerting pressure on the textile structure in the area of the contact surfaces.

Bei einer bevorzugten Ausgestaltung des textilen Gebildes ist die textile Basisschicht aus einem Filz gefertigt. Filz ist preiswert herstellbar und lässt sich unter Hitze und Druck leicht verformen. Filz hat außerdem mechanisch und akustisch dämpfende Eigenschaften. Für eine besonders umweltfreundliche Variante des textilen Gebildes kann der Filz außerdem aus recyceltem Textilmaterial gefertigt werden.In a preferred embodiment of the textile structure, the textile base layer is made of a felt. Felt is inexpensive to produce and can be easily deformed under heat and pressure. Felt also has mechanical and acoustic damping properties. For a particularly environmentally friendly variant of the textile structure, the felt can also be made from recycled textile material.

Um die Auslösung der Schaltfunktion zu erleichtern, ist es außerdem vorteilhaft, wenn in dem mindestens einen Schalterbereich die Anzahl der Polfäden zwischen den Oberflächen gegenüber der Anzahl der Polfäden in den Bereichen außerhalb des Schalterbereichs reduziert ist. Es reicht dann bereits ein geringer Druck, um die Kontaktflächen im Schalterbereich miteinander in Kontakt zu bringen.In order to facilitate the triggering of the switching function, it is also advantageous if, in the at least one switch area, the number of pile threads between the surfaces is reduced compared to the number of pile threads in the areas outside the switch area. It then already enough a slight pressure to bring the contact surfaces in the switch area with each other in contact.

Weitere Vorteile ergeben sich, wenn die Kontaktflächen des mindestens einen Schalterbereichs mit elektrischen Anschlussflächen im Randbereich des textilen Gebildes mit Hilfe der eingestrickten elektrisch leitfähigen Garne verbunden sind. Innerhalb des textilen Gebildes müssen dann keine Anschlussdrähte geführt werden. Sind mehrere Schalterbereiche vorhanden, so können diese gemeinsam von außen über die Anschlussflächen kontaktiert und beispielsweise mit einer Batterie oder einer Fahrzeugelektronik verbunden werden.Further advantages result if the contact surfaces of the at least one switch region are connected to electrical connection surfaces in the edge region of the textile structure with the aid of the knitted electrically conductive yarns. Within the textile structure then no connection wires must be performed. If a plurality of switch areas are present, they can be contacted together from the outside via the connection surfaces and, for example, connected to a battery or vehicle electronics.

Die Funktionalität des textilen Gebildes kann zudem dadurch erhöht werden, dass es eine Heizschicht aufweist, die aus einer leitfähigen Paste hergestellt ist. Die Paste kann durch ein Beschichtungsverfahren aufgebracht werden. Insbesondere bei Verwendung des textilen Gebildes zur Herstellung eines Innenraumteils eines Fahrzeugs kann durch die Heizschicht eine Innenraumheizung realisiert werden.The functionality of the textile structure can also be increased by having a heating layer made of a conductive paste. The paste can be applied by a coating process. In particular, when using the textile structure for producing an interior part of a vehicle, an interior heating can be realized by the heating layer.

Diese Heizschicht kann beispielsweise zwischen dem Abstandgestrick und der textilen Basisschicht angeordnet sein. Es ist jedoch auch möglich, die Heizschicht zwischen dem Abstandsgestrick und einer textilen Deckschicht anzuordnen.This heating layer can be arranged, for example, between the spacer fabric and the textile base layer. However, it is also possible to arrange the heating layer between the spacer fabric and a textile cover layer.

Zum Schutz der Oberfläche des textilen Gebildes kann die der Basisschicht abgewandte Oberfläche des textilen Gebildes mit einer dreidimensionalen keramischen Beschichtung versehen sein. Diese Beschichtung ist abriebfest und erhöht somit die mechanische Stabilität des textilen Gebildes. Die dreidimensionale Beschichtung kann insbesondere auf einem Träger aufgebrachte Plättchen aufweisen, die auch farbig gestaltet und in einem bestimmten Muster aufgebracht sein können. Dadurch kann mit der keramischen Beschichtung das textile Gebilde auch mit einem besonderen Design versehen werden.To protect the surface of the textile structure, the base layer facing away from the surface of the textile structure may be provided with a three-dimensional ceramic coating. This coating is resistant to abrasion and thus increases the mechanical stability of the textile structure. The three-dimensional coating may in particular have platelets applied to a support, which may also be colored and applied in a specific pattern. As a result, the textile structure can also be provided with a special design with the ceramic coating.

Außerdem kann die keramische Beschichtung Markierungen zur Kennzeichnung der Position des oder der Schalterbereiche des Abstandsgestricks aufweisen. Auf zusätzliche Betätigungselemente oder Markierungen der Schalterbereiche kann dadurch verzichtet werden. Durch Drücken der markierten Bereiche lassen sich die gewünschten Schaltfunktionen ausführen.In addition, the ceramic coating may have markings for identifying the position of the switch fabric or regions of the spacer fabric. On additional actuators or markers of the switch areas can be dispensed with. By pressing the marked areas, the desired switching functions can be carried out.

Die Erfindung betrifft außerdem ein Innenverkleidungsteil für ein Kraftfahrzeug, insbesondere ein Türinnenverkleidungsteil, das aus einem textilen Gebilde nach einem der Ansprüche 1 bis 10 hergestellt ist.The invention further relates to an interior trim part for a motor vehicle, in particular a door inner trim part, which is made of a textile structure according to one of claims 1 to 10.

Im Folgenden werden bevorzugte Ausführungsbeispiele erfindungsgemäßer textiler Gebilde mit Bezug auf die Zeichnung näher beschrieben.In the following, preferred embodiments of textile structures according to the invention are described in more detail with reference to the drawing.

Das in 1 gezeigte textile Flächengebilde 10 besteht aus einem Abstandsgestrick 11 und einer textilen Basisschicht 12, hier einem Filz, der aus recycelten Textilfasern hergestellt ist. In das Abstandsgestrick 11 sind zwei Schalterbereiche 13, 14 eingebracht, die von elektrisch leitfähigen Kontaktflächen 15, 16 bzw. 17, 18 in den Oberflächengestricken des Abstandsgestricks 11 gebildet sind. Die Kontaktflächen 15-18 werden durch Einstricken von elektrisch leitfähigem Garn gebildet. Dieses wird auch dazu verwendet, die Kontaktflächen 15-18 mit Anschlusskontaktflächen 19, 20 am Rand des textilen Gebildes 10 zu verbinden. Die übrigen Bereiche des Abstandsgestricks 11 und insbesondere die Polfäden sind aus elektrisch isolierenden Garnen hergestellt. Durch Druck auf die Kontaktflächen 15, 16 bzw. 17, 18 können diese zur Berührung gebracht und damit die Schalter geschlossen werden. Über die Anschlusskontaktflächen 19, 20 können die Schalterbereiche 13, 14 beispielsweise mit einer Fahrzeugelektronik verbunden werden.This in 1 shown textile fabrics 10 consists of a spacer fabric 11 and a textile base layer 12 Here is a felt made from recycled textile fibers. In the spacer fabric 11 are two switch areas 13 . 14 introduced by electrically conductive contact surfaces 15 . 16 respectively. 17 . 18 in the surface knits of the spacer knitted fabric 11 are formed. The contact surfaces 15 - 18 are formed by knitting of electrically conductive yarn. This is also used to contact surfaces 15 -18 with connection pads 19 . 20 on the edge of the textile structure 10 connect to. The remaining areas of the spacer knitted fabric 11 and in particular the pile threads are made of electrically insulating yarns. By pressure on the contact surfaces 15 . 16 respectively. 17 . 18 These can be brought into contact and thus the switches are closed. Via the connection contact surfaces 19 . 20 can the switch areas 13 . 14 For example, be connected to a vehicle electronics.

Zwischen dem Abstandsgestrick 11 und der Basisschicht 12 ist eine Heizschicht angeordnet, die von einer elektrisch leitfähigen Paste gebildet ist.Between the spacer fabric 11 and the base layer 12 a heating layer is formed, which is formed by an electrically conductive paste.

Die Oberseite des textilen Gebildes 10 ist zumindest bereichsweise von einer keramischen Beschichtung 22 aus einzelnen Plättchen 23 abgedeckt. Die Plättchen 23 sind aus einem abriebfesten Material gefertigt und können in einem bestimmten Muster aufgebracht werden. Zwei der Plättchen 23 sind als Markierungen ausgebildet, welche die Position der darunterliegenden Schalterbereiche 13, 14 kennzeichnen. Die Beschichtung 22 dient somit dem mechanischen Schutz des Gebildes 10 sowie dessen optischer Gestaltung.The top of the textile structure 10 is at least partially of a ceramic coating 22 from individual tiles 23 covered. The tiles 23 are made of an abrasion resistant material and can be applied in a specific pattern.
