Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines mit einem Bezug, insbesondere einem Lederbezug versehenen Ausstattungsteils für den Innenraum eines Kraftfahrzeugs, bei welchem der Bezug verformt und anschließend mit einem Träger verbunden wird, sowie ein nach diesem Verfahren hergestelltes Ausstattungsteil.The The invention relates to a method for producing a with a Cover, in particular a leather cover provided with equipment for the Interior of a motor vehicle, wherein the reference deformed and subsequently with a carrier is connected, as well as a manufactured according to this method piece of equipment.

Stand der TechnikState of the art

Aus der Offenlegungsschrift DE 199 11 815 A1 ist ein gattungsgemäßes Verfahren zur Herstellung lederbezogener Ausstattungsteile für den Kraftfahrzeuginnenraum bekannt. Dabei wird ein im Wesentlichen auf Sollmaß konfektionierter Lederbezug in ein Tiefziehwerkzeug eingelegt und durch Anlegen von Unterdruck gehalten. Anschließend wird mittels eines Spannrahmens eine auf Sollmaß geschnittene Schaumlage aus geschlossenzelligem, teilvernetzten Polyolefinschaum in das Tiefziehwerkzeug eingeführt, bis zum Erreichen des thermoplastischen Zustands erwärmt und auf den Lederbezug aufgelegt. Unter der Wirkung des Unterdrucks verbindet sich die Schaumlage mit dem Lederbezug ohne Verwendung zusätzlicher Klebmittel zu einem gegebenenfalls dreidimensional vorgeformten Ausstattungsteil, das durch nachfolgendes Hinterschäumen mit einem PUR-Schaum oder Verbinden mit einem vorgefertigten Trägerteil seine endgültige Gestalt erhält.From the publication DE 199 11 815 A1 is a generic method for producing leather-related fittings for the motor vehicle interior known. In this case, a leather cover made up essentially to the specified size is inserted into a deep-drawing tool and held by applying negative pressure. Subsequently, by means of a clamping frame, a cut to desired size foam layer of closed-cell, partially crosslinked polyolefin foam introduced into the thermoforming mold, heated to reach the thermoplastic state and placed on the leather cover. Under the effect of the vacuum, the foam layer combines with the leather cover without the use of additional adhesive to an optionally three-dimensionally preformed piece of equipment that receives its final shape by subsequent foam back with a polyurethane foam or bonding with a prefabricated support member.

Der relativ weiche Polyolefinschaum kann dem Ausstattungsteil zwar eine ansprechende Haptik verleihen, ist jedoch im Hinblick auf sein Klimaverhalten ungünstig. Darüber hinaus können nach diesem Verfahren nur Formteile mit relativ großen Biegeradien gefertigt werden.Of the relatively soft polyolefin foam can the equipment part Although a give an appealing haptic, but with regard to its climate behavior unfavorable. About that can out according to this method only molded parts with relatively large bending radii be made.

Aus der Praxis ist ferner bekannt, Lederbezüge für Ausstattungsteile aus einer Vielzahl von Segmenten herzustellen, die unter Ausbildung eines dreidimensionalen Formteils miteinander vernäht und nachfolgend mit dem Träger verklebt werden. Dieses Vorgehen ist einerseits aufwendig und kann zu einer optisch und/oder haptisch unbefriedigenden Häufung von Nähten führen.Out The practice is also known, leather upholstery for equipment from a To produce variety of segments, forming a three-dimensional Sewn together molding and subsequently with the carrier be glued. This procedure is both expensive and can an optically and / or haptically unsatisfactory accumulation of seams to lead.

Aus der DE 29 17 907 A1 ist ein Verfahren zur Herstellung einer Instrumententafel eines Pkw bekannt, bei welchem Verfahren vorgesehen ist, dass ein Laminat aus Leder und einem Flachmaterialstück aus einem Schaumstoff zusammengesetzt wird. Das Laminat wird mit einem getrennt hiervon hergestellten Basisteil (Träger) stoffschlüssig miteinander verbunden, und zwar innerhalb des Presswerkzeugs. Bei diesem Verfahren wird ein Laminat aus Leder und Schaumstoff in noch ebenem Zustand zwischen die Formhälften eines Gesenks gebracht, in em sich bereits der vorgefertigte, mit Klebstoff versehene Träger befindet. Durch Schließen der Formen wird das Bezugsmaterial dreidimensional verformt und gleichzeitig mit dem Träger verbunden, was insoweit ein übliches Kaschierverfahren darstellt.From the DE 29 17 907 A1 discloses a method for manufacturing a dashboard of a car, which method is provided that a laminate of leather and a flat piece of material is composed of a foam. The laminate is bonded together with a base part (carrier) produced separately therefrom, namely within the pressing tool. In this process, a laminate of leather and foam is placed in still flat condition between the mold halves of a die, in which already the prefabricated, provided with adhesive carrier is. By closing the molds, the cover material is deformed three-dimensionally and at the same time connected to the carrier, which is a conventional laminating method.

Aus der US 5,273,597 A ist ein Verfahren zum Thermoformen einer Abdeckhaut für eine Instrumententafel bekannt, wobei die Abdeckhaut aus einem Kunststofflaminat, umfassend eine PVC-Schicht und eine geschäumte Polyolefinschicht, besteht. Diese thermoplastisch verformbare Abdeckhaut wird bis zur Erreichung der Erweichungstemperatur erhitzt und mittels eines Spannrahmens in ein Tiefziehwerkzeug eingeführt, wo diese unter Anwendung von Unterdruck und unter Einwirkung von einem Gesenk und einer entsprechend ausgebildeten Matrize zu einem dreidimensionalen Formteil umgeformt wird. Dieses Verfahren eignet sich nicht zur Verarbeitung empfindlicher Bezugsmaterialien wie Leder.From the US 5,273,597 A For example, a method of thermoforming a cover skin for an instrument panel is known, wherein the cover skin consists of a plastic laminate comprising a PVC layer and a foamed polyolefin layer. This thermoplastically deformable covering skin is heated until the softening temperature is reached and introduced by means of a tentering frame into a deep-drawing tool, where it is converted to a three-dimensional molded part by application of negative pressure and under the action of a die and a correspondingly formed die. This method is not suitable for processing delicate cover materials such as leather.

Aufgabetask

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung komplex geformter lederbezogener Ausstattungsteile bereitzustellen, deren Bezug möglichst großstückig gefertigt ist.Of the Invention is based on the object, a process for the preparation to provide complex shaped leather-covered pieces of equipment their reference as possible made in large pieces is.

Lösungsolution

Die Erfindung wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The Invention is according to the invention with the features of claim 1. Advantageous embodiments emerge from the subclaims.

Die Erwärmung erfolgt auf der rückseitigen, nachfolgend dem Träger zugewandte Oberfläche des Bezugs, um die Narbung oder Struktur des Bezugs weitgehend zu erhalten. Aus verfahrenstechnischen Gründen wird der Bezug vor dem Einlegen in das Preßwerkzeug erwärmt. Durch die Entkopplung von Erwärmung und Umformen kann das Werkzeug besonders effizient genutzt werden. Die Erwärmung kann beispielsweise durch Bestrahlung des Bezugs mit IR-Strahlung erfolgen.The warming done on the back, below the carrier facing surface the reference to the grain or structure of the cover largely to receive. For procedural reasons, the reference before the Insertion in the pressing tool heated. By decoupling from warming and forming the tool can be used very efficiently. The warming can for example, by irradiation of the reference with IR radiation.

Der Bezug wird im Zuge des Preßvorgangs gleichzeitig randbeschnitten, wozu eine im Werkzeug umlaufende Schneidkante dienen kann. Ferner kann der Bezug beim Pressen auf einen definierten, insbesondere in Abhängigkeit von seiner gemessenen Dicke festgelegten Abstand komprimiert werden. Auch dieses Vorgehen schont die natürliche Narbung des Leders. Ein zuvor auf der rückseitigen Oberfläche des Bezugs vorzugsweise mittels eines thermoaktivierbaren Klebers vor dem Pressen aufgebrachtes Vlies, insbesondere ein Polyestervlies, kann dabei ein örtliches Dickenuntermaß des Bezugs ausgleichen.Of the Reference becomes simultaneous in the course of the pressing process cut to the edge, for which serve a circumferential cutting edge in the tool can. Furthermore, the reference during pressing on a defined, especially depending be compressed by its measured thickness specified distance. This procedure also protects the natural grain of the leather. A previously on the back Surface of the Cover preferably by means of a thermally activated adhesive before nonwoven applied to the pressing, in particular a polyester fleece, can be a local Thickness undersize of Balancing the reference.

Ein unter Anwendung dieses Verfahrens gefertiges Ausstattungsteil ist insbesondere im Innenraum eines Kraftfahrzeugs einsetzbar, beispielsweise als hochwertige Armauflage einer Fahrzeugtür oder Mittelkonsole sowie als Bezug eines Fahrzeugsitzes. Durch das erfindungsgemäße Verfahren können großflächige Bezugsteile mit komplexen Geometrien und engen Biegeradien geschaffen werden, die einstückig ausführbar sind und daher nicht aus mehreren Segmenten zusammen genäht werden müssen. Neben Lederbezügen lassen sich auch Gewebe, insbesondere solche mit einer ausgebildeten Oberflächenstruktur nach diesem Verfahren verarbeiten.One fabricated using this method fitting is used in particular in the interior of a motor vehicle, for example as a high-quality armrest of a vehicle door or center console as well as a reference of a vehicle seat. By the method according to the invention can large-area cover parts be created with complex geometries and tight bending radii, the one-piece executable are therefore not sewn together from several segments together have to. In addition to leather covers can also be tissue, especially those with a trained surface structure process according to this procedure.

Die Figuren stellen beispielhaft und schematisch die Abläufe bei der Durchführung eines erfindungsgemäßen Verfahrens dar.The Figures provide examples and schematically the processes the implementation a method according to the invention represents.

Es zeigen:It demonstrate:

1 das Vorbereiten eines Lederbezugs für den Preßvorgang 1 Preparing a leather cover for the pressing process

2 das nachfolgende Umformen des Lederbezugs in einem Preßwerkzeug 2 the subsequent forming of the leather cover in a press tool

3 die Fertigstellung des Ausstattungsteils 3 the completion of the equipment

Wie aus 1 ersichtlich, wird ein Lederbezug 1 mit der zuvor gemessenen mittleren Dicke d1 rückseitig mit einer dünnen Schicht eines thermoaktivierbaren Klebers 2 versehen, bevor auf diesen ein Polyestervlies 3 mit einer Dicke d2 aufgelegt wird. Die Dicke d2 des Polyestervlieses 3 ist dabei größer gewählt als die Dicke d1 des Lederbezugs. Durch Bestrahlen der Rückseite des Lederbezugs 1 mittels einer IR-Lampe 4 wird der Kleber 2 aktiviert, so dass sich Polyestervlies 3 und Lederbezug 1 miteinander verbinden.How out 1 seen, becomes a leather cover 1 with the previously measured average thickness d1 on the back with a thin layer of a thermally activated adhesive 2 provided before on this a polyester fleece 3 is applied with a thickness d2. The thickness d2 of the polyester fleece 3 is chosen larger than the thickness d1 of the leather cover. By irradiating the back of the leather cover 1 by means of an IR lamp 4 becomes the glue 2 activated, so that polyester fleece 3 and leather cover 1 connect with each other.

Der so geschaffene Verbund wird in ein Preßwerkzeug 5 mit einer oberen Formhälfte 6 und einer unteren Formhälfte 7 eingelegt, die eine umlaufende Schneidkante 10 aufweisen (2). Die Formhälften 6, 7 werden so zueinander verfahren, dass sich zwischen ihnen im Wesentlichen, insbesondere im Bereich großflächiger Sichtflächen des Lederbezugs, ein Abstand a einstellt, der geringer ist als die zuvor gemessene Dicke d1 des Lederbezugs.The composite created in this way becomes a pressing tool 5 with an upper mold half 6 and a lower mold half 7 inserted, the one circumferential cutting edge 10 exhibit ( 2 ). The mold halves 6 . 7 are moved to each other so that between them substantially, in particular in the field of large-scale visible surfaces of the leather cover, a distance a sets, which is less than the previously measured thickness d1 of the leather cover.
