Abstract

The element (3) is formed of conductive carbon fibres woven into a rectangular blanket (4) of relatively high electric resistance between two electrodes (5). The latter are metallic contact wires (6) woven or stitched into opposite sides of the blanket with a sepn (a) which determines the surface resistance and heating capacity. Alternatively one electrode may be laid along part of the centre line of the blanket from one edge, with the other electrode formed by a continuous wire around the other three sides. ADVANTAGE - Optimal comfort is guaranteed by uniform and rapid heating of material permeable to air and moisture.

Description

Die Erfindung betrifft eine Heizmatte gemäß dem Oberbegriff des Patentanspruches 1, insbesondere für eine elektrische Sitzhei­ zung in einem Kraftfahrzeugsitz.The invention relates to a heating mat according to the preamble of Claim 1, in particular for an electric seat tongue in a motor vehicle seat.

Aus der DE 25 43 907 A1 ist eine elektrisch beheizte Heizmatte bekannt, die aus einem flexiblen Platte aus einem vulkanisier­ ten, kohlenstoffhaltigen Widerstandsmaterial besteht.DE 25 43 907 A1 describes an electrically heated heating mat known from a flexible plate from a vulcanized carbon-containing resistance material.

Die flächig ausgeführten, aus einem gut leitenden Material be­ stehenden Anschlußelektroden sind zur Herstellung einer Ver­ bindung mit ausreichend geringen Übergangswiderstand zwischen zwei Lagen des Widerstandsmateriales eingesetzt und unter Druck verklebt oder einvulkanisiert.The flat, be made of a highly conductive material standing connection electrodes are used to produce a ver binding with sufficiently low contact resistance between two layers of the resistance material inserted and under pressure glued or vulcanized.

Eine nach diesem relativ aufwendigen Verfahren hergestellte Heizmatte ist jedoch weder Luft- noch Feuchtigkeitsdurchlässig und wegen des dadurch verminderten Sitzkomfort für einen Fahr­ zeugsitz nur im eingeschränkten Maße verwendbar.A manufactured by this relatively expensive process However, the heating mat is not permeable to air or moisture and because of the reduced seating comfort for a ride Tool seat can only be used to a limited extent.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Heizmatte darzustellen, welche leicht und kostengünstig her­ stellbar ist und infolge ihrer Luft- und Feuchtigkeitsdurch­ lässigen Ausführung sowie einer gleichmäßigen und schnell ein­ setzenden Erwärmung einen optimalen Sitzkomfort gewährleistet.The invention has for its object a generic Represent heating mat, which is easy and inexpensive to manufacture is adjustable and due to their air and moisture through casual design as well as an even and quick one setting heating ensures optimal seating comfort.

Erfindungsgemäß wird die Aufgabe mit den kennzeichnenden Merk­ malen des Patentanspruches 1 gelöst, wobei die Merkmale der Unteransprüche vorteilhafte Aus- und Weiterbildungen kenn­ zeichnen.According to the invention the task with the characteristic note paint the claim 1, the characteristics of  Advantageous training and further education to draw.

Mit der erfindungsgemäßen Lösung wird es möglich, eine ausrei­ chende elektrische Kontaktierung zwischen den als Kontaktdraht ausgebildeten Elektroden und dem relativ schlecht leitenden, aus Kohlenstoffasern bestehenden Gewebe herzustellen, so daß damit die Verwendung eines derartigen Gewebes für eine sich sehr gleichmäßig erwärmende Heizmatte, insbesondere für eine elektrische Sitzheizung in einem Kraftfahrzeugsitz ermöglicht wird.With the solution according to the invention it becomes possible to have one appropriate electrical contact between the as a contact wire trained electrodes and the relatively poorly conductive, fabric made of carbon fibers, so that hence the use of such a fabric for yourself very even heating mat, especially for one electrical seat heating in a motor vehicle seat enables becomes.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt und wird im folgenden näher be­ schrieben. Es zeigen:An embodiment of the invention is in the drawing is shown schematically and will be described in more detail below wrote. Show it:

Fig. 1 einen Fahrzeugsitz mit einer ersten Ausführung einer erfindungsgemäßen Heizmatte; Fig. 1 shows a vehicle seat with a first embodiment of a mat according to the invention;

Fig. 2 eine zweite Ausführung einer erfindungsgemäßen Heiz­ matte mit geänderter Anordnung der Drahtelektroden. Fig. 2 shows a second embodiment of a heating mat according to the invention with a modified arrangement of the wire electrodes.

In Fig. 1 ist ein mit dem Bezugszeichen 1 bezeichneter Sitz eines Kraftfahrzeuges angedeutet, in dessen Sitzfläche 2 eine erfindungsgemäße Heizmatte 3 angeordnet ist. Die Heizmatte 3 besteht aus einem stromleitenden Gewebe 4 aus Kohlenstoffasern, welches einen relativ hohen elektrischen Widerstand aufweist und sich aufgrund dieses elektrischen Widerstandes bei Strom­ durchfluß erwärmt.In Fig. 1, designated by the reference numeral 1 is indicated seat of a motor vehicle, a heating mat according to the invention 3 is arranged in the seat surface 2. The heating mat 3 consists of a current-conducting fabric 4 made of carbon fibers, which has a relatively high electrical resistance and is heated due to this electrical resistance when current flows.

Für den Anschluß an eine Bordspannungsquelle sind in die Heiz­ matte 3 jeweils in einem bestimmten Abstand "a" zueinander min­ destens zwei Elektroden 5 eingearbeitet. Erfindungsgemäß sind die Elektroden 5 als metallische Kontaktdrähte 6 ausgebildet und in das Gewebe 4 eingewoben, eingenäht oder eingestrickt. For connection to an on-board voltage source, at least two electrodes 5 are worked into the heating mat 3 at a certain distance "a" from one another. According to the invention, the electrodes 5 are designed as metallic contact wires 6 and are woven, sewn or knitted into the fabric 4 .

Vorzugsweise werden dazu flexible, relativ feine Drähte aus einem gutleitenden Material verwendet, wobei ein Kontaktdraht 6 jeweils mehrere, in den Darstellungen nicht sichtbare, im ge­ ringen Abstand und im wesentlichen parallel zueinander verlau­ fender Einzeldrähte umfassen kann.For this purpose, flexible, relatively fine wires made of a highly conductive material are preferably used, a contact wire 6 in each case comprising a plurality of individual wires which are not visible in the illustrations, at a small distance and essentially parallel to one another.

Der relativ hohe Übergangswiderstand, welcher an einer einzel­ nen Kontaktstelle zwischen einem Kontaktdraht 6, 7, 8 und dem Gewebe 4 gegeben ist, wird in der Summe infolge der innigen Verbindung zwischen den Kontaktdrähten 6 und dem Gewebe 4 sowie der daraus resultierenden Vielzahl einzelner Kontaktstellen derart vermindert, daß an diesen Kontaktstellen keine, über die beabsichtigte großflächige Erwärmung der Heizmatte 3 hinaus­ gehende Erwärmung eintritt. Durch die parallele Anordnung meh­ rerer Einzeldrähte eines Kontaktdrahtes 6 für jeweils eine Elektrode 5 kann die Anzahl der Kontaktstellen noch verviel­ facht, bzw. der Übergangswiderstand weiter minimiert werden.The relatively high contact resistance, which is given at a single contact point between a contact wire 6 , 7 , 8 and the tissue 4 , is in total due to the intimate connection between the contact wires 6 and the tissue 4 and the resulting large number of individual contact points reduces that at these contact points there is no heating beyond the intended large-area heating of the heating mat 3 . Due to the parallel arrangement of several individual wires of a contact wire 6 for one electrode 5 each, the number of contact points can be multiplied even further, or the contact resistance can be further minimized.

Die Kontaktdrähte 6 werden mit einem, im wesentlichen gleich­ bleibenden Abstand "a" voneinander in die Heizmatte 3 einge­ bracht, wobei mit diesem Abstand "a" der Flächenwiderstand und damit die Heizleistung der Heizmatte 3 bestimmt wird. Dabei ist die Form der Anordnung der Kontaktdrähte 6 von unterge­ ordneter Bedeutung und wird von den konkreten Bedingungen be­ stimmt. So ist in einer Ausführung nach Fig. 1 eine Anordnung mit parallel zueinander verlaufenden Kontaktdrähten 6 darge­ stellt, während in einer Ausführung nach Fig. 2 ein zentrischer Kontaktdraht 7 von einem im Randbereich der Heizmatte 3 U-förmig umlaufenden Kontaktdraht 8 mit einem in allen Ab­ schnitten im wesentlichen gleichbleibenden Abstand "a" umgeben wird.The contact wires 6 are brought into the heating mat 3 with a substantially constant distance "a" from one another, with this distance "a" the surface resistance and thus the heating power of the heating mat 3 being determined. The shape of the arrangement of the contact wires 6 is of subordinate importance and is determined by the specific conditions. So 1 in an embodiment according to FIG. An arrangement with mutually parallel contact wires 6 illustrates Darge, while in an embodiment shown in FIG. 2, a centric contact wire 7 from a 3 U-shaped encircling the edges of the mat contact wire 8 having an in all From cut substantially constant distance "a" is surrounded.
