Definitions

  • the invention relates to a seat heater for integrated installation in vehicle seats, consisting of at least two or more segments or surfaces in any shape, which consist of several flat, electrically interconnected radiators, which are adapted to the individual section design, and wherein the connection between the individual radiators are each formed by a heating conductor and this heating conductor is inserted in both ends in partial lengths in each of the radiators engaging envelope.
  • the two heated surfaces of the seat heating are stabilized by an angled arrangement of the connecting webs and reinforcement of the corresponding heating conductor sections by knitted copper tape or copper tape fabric.
  • the reinforced connection points between the heating wire and the copper braid are visible on the surface of the covering material in the case of a heater lying directly under the covering material.
  • the object of the present invention is to avoid these disadvantages and sources of danger and to form a smooth transition between the individual radiators in the case of seat heating of the type mentioned, which also adapts to this in an individual seat design and shape.
  • the pliability of the electrically connected radiators and the use of heat conductors of low thickness can be specified. Further details can be found in the following description and the exemplary embodiments.
  • the heating surface is built up on a removable carrier foil 2.
  • a layer 4 which is provided with an adhesive side and which consists of a highly plastic base, is connected to the carrier film 2. On the opposite side, layer 4 completely receives a heating conductor 3.
  • the layer 5 lying on top is a non-adhesive cover layer; the carrier film 2 is removed immediately before installation and the layer 4 is fixed to the inner surface of the cover.
  • Layer 5 covers the inside, i.e. to the upholstered body and is movable relative to it.

Description

Die Erfindung betrifft eine Sitzbeheizung zum integrierten Einbau in Fahrzeugsitze, bestehend aus mindestens zwei oder mehreren Segmenten bzw. Flächen in beliebiger Formgebung, wobei diese aus mehreren flächigen, elektrisch miteinander verbundenen Heizkörpern bestehen, die der abschnittsweisen individuellen Sitzgestaltung angepaßt sind, und wobei die Verbindung zwischen den einzelnen Heizkörpern jeweils durch einen Heizleiter gebildet ist und dieser Heizleiter ineiner beidends in Teillängen in jeden der Heizkörper eingreifenden Umhüllung einliegend geführt ist.The invention relates to a seat heater for integrated installation in vehicle seats, consisting of at least two or more segments or surfaces in any shape, which consist of several flat, electrically interconnected radiators, which are adapted to the individual section design, and wherein the connection between the individual radiators are each formed by a heating conductor and this heating conductor is inserted in both ends in partial lengths in each of the radiators engaging envelope.

Aus der EP-A-O 226 692 ist eine Sitzbeheizung der eingangs genannten Art bekannt. Dabei geht es um eine sichere, spannungsfreie Verlegung des Heizleiters im Bereich des sogenannten "Abspanngrabens", der im Polsterkern zwischen den elektrisch beheizten Sitz- bzw. Lehnenflächen angeordnet ist, wobei unterhalb des Abspanngrabens ein im Polsterkern eingebundener Spanndraht zur Befestigung und Spannung des Bezuges dient.From EP-A-O 226 692 a seat heater of the type mentioned is known. It is a matter of a safe, tension-free laying of the heating conductor in the area of the so-called "guy trench", which is arranged in the upholstery core between the electrically heated seat or backrest surfaces, below the guy trench a tension wire integrated in the upholstery core serves to fasten and tension the cover .

In der EP-A-O 226 692 werden die beiden beheizten Flächen der Sitzheizung durch eine winklige Anordnung der Verbindungsstege und Verstärkung der entsprechenden Heizleiterabschnitte durch Kupferbandgewirke oder Kupferbandgewebe stabilisiert. Dabei muß allerdings in Kauf genommen werden, daß sich bei einer direkt unter dem Bezugstoff liegenden Heizung die verstärkten Verbindungsstellen zwischen Heizdraht und Kupferlitze an der Oberfläche des Bezugstoffes abzeichnen. Ferner besteht die Gefahr des Abknickens und der an den Knickstellen auftretenden örtlichen Überhitzungen durch eine elektrische Verbindung zwischen Heizdraht und Kupferlitze.In EP-AO 226 692, the two heated surfaces of the seat heating are stabilized by an angled arrangement of the connecting webs and reinforcement of the corresponding heating conductor sections by knitted copper tape or copper tape fabric. However, it must be accepted that the reinforced connection points between the heating wire and the copper braid are visible on the surface of the covering material in the case of a heater lying directly under the covering material. Furthermore, there is Danger of kinking and local overheating occurring at the kinks due to an electrical connection between the heating wire and the copper wire.

Aufgabe der vorliegenden Erfindung ist es, diese Nachteile und Gefahrenquellen zu vermeiden und bei einer Sitzbeheizung der eingangs genannten Art einen weichen Übergang zwischen den einzelnen Heizkörpern zu bilden, der auch bei einer individuellen Sitzgestaltung und Formgebung sich dieser anpaßt.The object of the present invention is to avoid these disadvantages and sources of danger and to form a smooth transition between the individual radiators in the case of seat heating of the type mentioned, which also adapts to this in an individual seat design and shape.

Erfindungsgemäß wird diese Aufgabe durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Eine bevorzugte Ausführung der erfindungsgemäßen Sitzbeheizung ist im Patentanspruch 2 beschrieben.According to the invention, this object is achieved by the features specified in claim 1. A preferred embodiment of the seat heating according to the invention is described in claim 2.

Als besondere Eigenschaft der erfindungsgemäßen Sitzbeheizung kann die Schmiegsamkeit der elektrisch miteinander verbundenen Heizkörper sowie die Verwendung von Heizleitern geringer Stärke angegeben werden. Weitere Einzelheiten sind der nachfolgenden Beschreibung und den Ausführungsbeispielen zu entnehmen.As a special property of the seat heating according to the invention, the pliability of the electrically connected radiators and the use of heat conductors of low thickness can be specified. Further details can be found in the following description and the exemplary embodiments.

Die beigefügte Zeichnung zeigt eine beispielsweise Lösung.

  • Figur 1 zeigt die Verbindung von zwei Heizkörpern
  • Figur 2 zeigt einen Schnitt I-I aus Figur 1.
The attached drawing shows an example of a solution.
  • Figure 1 shows the connection of two radiators
  • FIG. 2 shows a section II from FIG. 1.

Die Heizfläche ist auf einer abziehbaren Tragfolie 2 aufgebaut. Eine zur Tragfolie 2 mit einer Klebeseite versehene Schicht 4, die aus einer hochplastischen Basis besteht, ist mit der Tragfolie 2 verbunden. An der gegenüberliegenden Seite nimmt die Schicht 4 einen Heizleiter 3 vollständig auf.The heating surface is built up on a removable carrier foil 2. A layer 4, which is provided with an adhesive side and which consists of a highly plastic base, is connected to the carrier film 2. On the opposite side, layer 4 completely receives a heating conductor 3.

Die weiter aufliegende Schicht 5 ist eine nach außen nichtklebende Abdeckschicht; die Tragfolie 2 wird unmittelbar vor dem Einbau entfernt und die Schicht 4 an der Innenfläche des Bezuges fixiert.The layer 5 lying on top is a non-adhesive cover layer; the carrier film 2 is removed immediately before installation and the layer 4 is fixed to the inner surface of the cover.

Die Schicht 5 deckt zur Innenseite, d.h. zum Polsterkörper ab und ist diesem gegenüber beweglich.Layer 5 covers the inside, i.e. to the upholstered body and is movable relative to it.
