Die Erfindung betrifft eine Automobilsitzheizung und insbesondere eine nachrüstbare Automobilsitzheizung.The invention relates to an automobile seat heater and in particular to a retrofittable automobile seat heater.
Bekanntlich werden die Sitze einer zunehmenden Zahl von Personenkraftfahrzeugen und Nutzfahrzeugen als Serienausstattung oder als Sonderzubehör ab Werk mit elektrischen Automobilsitzheizungen ausgestattet. Der nachträgliche Einbau einer solchen Sitzheizung in Originalausführung ist nur mit sehr großem Aufwand oder gar nicht möglich. Aus diesem Grund wurde eine Reihe von nachrüstbaren Automobilsitzheizungen entwickelt, die als Auflagesitzheizungen ähnlich elektrischen Heizkissen, die mit Bändern an der Sitzoberfläche befestigt werden, oder als Sitzschonbezüge mit integrierter Sitzheizung gehandelt werden, die paßgenau für die einzelnen Sitze der verschiedenen Fahrzeuge gefertigt und über Sitz und Lehne gestülpt werden.It is known that the seats of an increasing number of passenger cars and commercial vehicles are equipped with electric automobile seat heaters as standard equipment or as special accessories. The subsequent installation of such a seat heater in the original version is only possible with great effort or not at all. For this reason, a series of retrofittable automotive seat heaters has been developed, which are sold as support seat heaters similar to electric heating pads, which are attached to the surface of the seat with straps, or as seat protectors with integrated seat heating, which are manufactured to fit the individual seats of the various vehicles and are suitable for seat and The backrest can be pulled over.
Diese bekannten Nachrüst-Automobilsitzheizungen verwenden relativ dicke isolierte Heizlitzen aus Kupfer, deren mechanische Festigkeit relativ niedrig ist. Da die Automobilsitzheizung bei nicht fachgerechtem Einbau oder nicht exakt paßgenauen Heizelementen Falten bildet, kommt es zu Knicken in der Kupferlitze. Durch Fahrzeug- und Sitzschwingungen entstehen hohe Biegewechselbeanspruchungen, die im Knickbereich zum Bruch von Einzeldrähten der Sitze bereits nach kurzer Zeit führen. Daraus resultiert dann eine örtliche Überhitzung, die als Hot Spot bezeichnet wird, und die zum Entstehen von Bränden führen kann. Um dieser Gefahr zu begegnen, werden die Heizmatten sehr dick gebaut, um die Faltenbildung zu unterbinden. Ferner werden Spannrahmen aus Federstahldrähten eingesetzt. Bei dicken Heizmatten tritt zwar keine Faltenbildung mehr auf, die Aufwärmzeiten sind jedoch sehr lang. Ferner verändern und beeinträchtigen sie Sitzkomfort und Sitzklima.These known retrofit automotive seat heaters use relatively thick insulated copper heating strands, the mechanical strength of which is relatively low. Since the automotive seat heating folds when not installed properly or the heating elements do not fit exactly, there is a kink in the copper wire. Vehicle and seat vibrations result in high bending stresses, which in the kink area lead to the breakage of individual wires in the seats after a short time. This then results in local overheating, referred to as a hot spot, which can lead to fires. In order to counter this danger, the heating mats are built very thick to prevent the formation of wrinkles. Spring steel wire stenter frames are also used. Thick wrinkles no longer appear on thick heating mats, but the warm-up times are very long. Furthermore, they change and impair seating comfort and seating climate.
Schonbezüge mit integrierten Sitzheizungen können entgegen vom Markt geforderten unterschiedlichsten Formen, Farben und Materialien aus wirtschaftlichen Gründen nur in wenigen Varianten angeboten werden.For economical reasons, protective covers with integrated seat heating can only be offered in a few variants, contrary to the different shapes, colors and materials required by the market.
Die der Erfindung zugrundeliegende Aufgabe besteht nun darin, eine Automobilsitzheizung, insbesondere eine nachrüstbare Automobilsitzheizung zu schaffen, die als Massenartikel gefertigt werden kann und die sich ohne Sicherheitsrisiken und Komfortnachteile für jeden bekannten Automobilsitz eignet.The object on which the invention is based is now to provide an automobile seat heater, in particular a retrofittable automobile seat heater, which can be mass-produced and which is suitable for any known automobile seat without safety risks and comfort disadvantages.
Diese Aufgabe wird erfindungsgemäß durch eine Automobilsitzheizung, insbesondere durch eine nachrüstbare Automobilsitzheizung gelöst, die ein dünnes, elektrisch isolierendes, dreidimensional elastisches, Luft- und feuchtigkeitsdurchlässiges Trägermaterial, ein auf das Trägermaterial aufgebrachtes elastisches Flächenheizelement mit Freiräume aufweisender netzartiger Struktur in Parallelleiteranordnung mit dreidimensionaler Verformbarkeit, einen luft- und feuchtigkeitsdurchlässigen elastischen Klebefilm, der auf das Flächenheizelement aufgebracht ist und dieses mit dem Trägermaterial durch die Freiräume in der netzartigen Struktur hindurch haftend verbindet, und eine auf den Klebefilm aufgebrachte und davon lösbare Schutzfolie aufweist, wobei die Haftkraft des Klebefilms für die Haftbefestigung an der Rückseite eines Automobilsitzbezugs ausgelegt ist.This object is achieved according to the invention by an automobile seat heater, in particular by a retrofittable automobile seat heater, which has a thin, electrically insulating, three-dimensionally elastic, air and moisture-permeable carrier material, an elastic surface heating element applied to the carrier material and a net-like structure with free spaces in a parallel conductor arrangement with three-dimensional deformability air- and moisture-permeable elastic adhesive film, which is applied to the surface heating element and adhesively connects it to the carrier material through the free spaces in the net-like structure, and has a protective film applied to and detachable from the adhesive film, the adhesive force of the adhesive film being used for the adhesive attachment the back of an automobile seat cover is designed.
Die erfindungsgemäße Automobilsitzheizung kann sehr dünn ausgeführt werden, da die Bildung von Falten aufgrund des verwendeten Flächenheizelements, das Gegenstand der Patentanmeldungen P 40 20 580.0 bzw. P 41 01 290.9 ist, keinerlei Sicherheitsrisiko darstellt. Aufgrund des dünnen Aufbaus wird die Heizwirkung in sehr kurzer Zeit fühlbar. Sitzkomfort und Sitzklima werden nur minimal beeinträchtigt.The automobile seat heater according to the invention can be made very thin, since the formation of wrinkles due to the surface heating element used, which is the subject of patent applications P 40 20 580.0 and P 41 01 290.9, does not pose any safety risk. Due to the thin structure, the heating effect can be felt in a very short time. Seating comfort and seating climate are only minimally affected.
Zweckmäßigerweise ist der Klebefilm eine beidseitig klebende Klebefolie. Solche permanent haftenden Kleber, die eine hohe Berührungshaftung aufweisen, sind im Handel erhältlich.The adhesive film is expediently a double-sided adhesive film. Such permanent adhesives, which have a high contact adhesion, are commercially available.
Bevorzugt wird als Trägermaterial ein durch ein textiles Flächengebilde gestütztes dünnes Polstermaterial (z.B. Schaumstoff).A thin cushion material (e.g. foam) supported by a textile fabric is preferred as the carrier material.
Die Automobilsitzheizung eignet sich insbesondere für die haftende Befestigung auf der Rückseite eines Schonbezugs, der in der gewünschten Form, Farbe und Größe bereitgestellt wird und auf den die Automobilsitzheizung nach Entfernen der Schutzfolie in einfacher Weise gut haftend aufgebracht werden kann.The automobile seat heater is particularly suitable for adhesive attachment to the back of a protective cover, which is provided in the desired shape, color and size and to which the automobile seat heater can be easily adhered after removal of the protective film.
Die nachrüstbare Automobilsitzheizung kann aus einem für Sitz und Lehne durchgehenden Trägermaterial bestehen, wobei die Flächenheizelemente im Sitz- und Lehnenbereich vorgesehen sind, während der dazwischen liegende Mittelbereich eine unbeheizte Fläche ist, die sich für die Aufnahme der elektrischen Anschlüsse und deren seitliches Herausführen eignet.The retrofittable automotive seat heating can consist of a continuous support material for the seat and backrest, the surface heating elements being provided in the seat and backrest area, while the middle area in between is an unheated area which is suitable for receiving the electrical connections and leading them out laterally.
Anhand einer Zeichnung, die einen Querschnitt durch eine Ausführungsform der Automobilsitzheizung zeigt, wird die Erfindung näher erläutert.The invention is explained in more detail with reference to a drawing which shows a cross section through an embodiment of the automobile seat heating.
Die in der Zeichnung gezeigte nachrüstbare Automobilsitzheizung besteht aus einem dünnen bahnförmigen Trägermaterial 4 aus textilverstärktem Schaumstoff- Auf dieses Trägermaterial wird ein Flächenheizelement 2 mit netzartiger Struktur aufgelegt, das Freiräume 5 aufweist und dreidimensional verformbar ist. Auf das Flächenheizelement 2 wird nun ein elastischer, luft- und feuchtigkeitsdurchlässiger Kunstharzklebe-film 3 aufgedrückt, der einseitig mit der Schutzfolie abgedeckt ist. Der Kunstharzklebefilm 3 geht durch die 2The retrofittable automotive seat heating shown in the drawing consists of a thin web-shaped carrier material 4 made of textile-reinforced foam. A flat heating element 2 with a net-like structure is placed on this carrier material, which has free spaces 5 and is three-dimensionally deformable. An elastic, air and moisture-permeable synthetic resin adhesive film 3, which is covered on one side with the protective film, is now pressed onto the surface heating element 2. The synthetic resin adhesive film 3 goes through the second
