Description
Innenverkleidungsformteil für KraftfahrzeugeInterior trim molding for motor vehicles
Die Erfindung betrifft ein Innenverkleidungsformteil für Kraftfahrzeuge, insbesondere für deren Armaturentafel, TUr-und Dachverkleidungen, aus einem Faserstofformpreßkörper.The invention relates to an interior trim molding for motor vehicles, especially for their dashboard, door and roof cladding, made from a molded fibrous material.
Innenverkleidungsformteile dienen heute nicht allein der Verkleidung und Verschönerung des Innenraums eines Eraftfahrzeugs, sondern haben zunehmend Bedeutung für den Insassenschutz bei Unfällen gewonnen. Zunächst begnügte man sich, die Innenverkleidung aus Blech mit einer Schaumstoffauflage zu versehen.Nowadays, molded interior trim parts are not only used for cladding and beautification of the interior of an electric vehicle, but are becoming increasingly important won for occupant protection in the event of an accident. At first they were content with the interior paneling to be provided from sheet metal with a foam pad.
Es stellte sich jedoch heraus, daß der Schaumstoff für die Dämpfung der beim Aufprall auftretenden Kräfte allein zu schwach, das darunterliegende Blech dagegen zu starr ist, so daß die Verletzungsgefahr kaum gemindert wurde.However, it turned out that the foam was used for cushioning the forces occurring on impact alone are too weak, the sheet metal underneath on the other hand, it is too rigid, so that the risk of injury was hardly reduced.
Man ist deshalb allgemein dazu übergegangen, die Innenverkleidungsformteile als Schaumpreßkörper aus Faserstoff herzustellen.A general move has therefore been made to the molded interior trim parts to be produced as a molded foam body from fibrous material.
Diese Faserstofformpreßkörper haben zunächst einmal den Vorteil eines wesentlich geringeren Gewichtes, sind aber andererseits für den normalen Gebrauch genügend formstabil.These molded fiber molded bodies initially have the advantage of one of significantly lower weight, but on the other hand are suitable for normal use sufficiently dimensionally stable.
Aus dem Verformungsverhalten beim Aufprall zeigen diese Formteile bei gunstiger Formgebung wesentlich bessere Eigenschaften als schaumstoffbeschichtetes Blech, so daß die Verletzungsgefahr wesentlich verringert werden konnte. Zusätzlich werden diese Faserstofformpreßkörper meist noch mit einer Schaumstoffschicht versehen.These molded parts show the deformation behavior on impact If the shape is favorable, it has significantly better properties than a foam-coated one Sheet metal, so that the risk of injury could be significantly reduced. Additionally will this Fibrous molded bodies mostly still with a foam layer Mistake.
Die ideale Lösung war jedoch damit noch nicht gefunden. Insbesondere bei großflächigen Armaturentafeln erwies sich das Faserstofformpreßteil beim Aufprall einer Person als zu wenig stabil da der Verformungsweg zu lang war. Um dennoch die erforderliche Stabilität zu erzielen wurden an das Faserstofformteil Verstärkungen angenietet. Diese zusätzliche Maßnahme erhöhte das Gewicht jedoch wieder beträchtlich.However, the ideal solution had not yet been found. In particular In the case of large dashboards, the molded fiber molded part proved itself on impact a person as not stable because the deformation path was too long. To still the To achieve the necessary stability, reinforcements were attached to the molded fiber material riveted. However, this additional measure again increased the weight considerably.
Außerdem ist die Steifheit an den verstärkten Stellen 8o groß, daß das Verformungsverhalten unbefriedigend ist.In addition, the rigidity at the reinforced points 8o is great that the deformation behavior is unsatisfactory.
Der Erfindung liegt somit die Aufgabe zugrunde, ein Innenverkleidungsformteil aus einem Faserstofformpreßkörper so zu gestalten, daß hohe Stabilität, günstiges Verformungsverhalten und geringes Gewicht kombiniert sind.The invention is therefore based on the object of a molded interior trim part to make from a molded fiber molded body so that high stability, cheap Deformation behavior and low weight are combined.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Rückseite (beim Aufprall die Zugzone) des Faserstofformpreßkörpers wenigstens teilweise mit einer Matte beschichtet ist.This object is achieved according to the invention in that the back (on impact, the tensile zone) of the molded fibrous molded body at least partially a mat is coated.
Es hat sich herausgestellt, daß die Stabilität und das Verformungsverhalten durch die zusatzliche Anbringung der Matte wesentlich verbessert werden konnte. Diese Verbesserung konnte mit nur unwesentlich erhöhtem Gewicht des gesamten Innenverkleidungsformteil erzielt werden.It has been found that the stability and deformation behavior could be significantly improved by the additional attachment of the mat. This improvement could be achieved with only insignificantly increased weight of the entire interior trim molding be achieved.
Als Material für die Matte bieten sich wegen des geringen Gewichtes und hoher Zugfestigkeit Kunststoffe an, wie z.B.The material used for the mat is due to its low weight and high tensile strength plastics, such as
Polyester, Polyamid oder Glasfaser. Dabei ist es zweckmäßig, die Matte als Gewebe auszubilden.Polyester, polyamide or fiberglass. It is useful to use the mat train as a tissue.
Die Beschichtung des Faserstofformpreßkörpers mit der Matte, kann, wie die Erfindung ferner vorsieht, durch Verklebung erfolgen. Da in den meisten Fällen derartige Innenverkleidungsformteile noch mit einer zusätzlichen Schaumstoffschicht versehen werden, ergibt sich eine besonders vorteilhafte Art der Verklebung dadurch, daß die Matte mit dem Easerstofformpreßkörper verschäumt wird. Damit die Verschäumung in einem Arbeitsgang erfolgen kann ist gemäß der Erfindung vorgesehen, den Faserstofformpreßkörper mit Löchern zu versehen. Durch diese Löcher kann der Schaumstoff auch an die Rückseite des Faserstofformpreßkörpers gelangen und dort die Verklebung mit der Matte herstellen. Dabei hat sich als ein besonders gut verklebender Schaumstoff Polyurethan erwiesen.The coating of the molded fiber molded body with the mat can, as the invention also provides, take place by gluing. As in most Cases of such molded interior trim parts with an additional foam layer are provided, a particularly advantageous type of bonding results from the fact that that the mat is foamed with the Easerstofformpreßkörper. So that the foaming can take place in one operation is provided according to the invention, the molded fiber molded body to provide holes. The foam can also be attached to the back through these holes of the molded fiber molded body and produce the bond with the mat there. Polyurethane has proven to be a particularly good adhesive foam.
Schließlich ist gemäß der Erfindung vorgeschlagen, daß die Innenverkleidungsformteil mit einer hautförmigen Oberlage umgeben ist. Diese ermöglicht nicht nur ein sauberes Auschäumen, sondern dient auch der Verschönerung des Formteiles.Finally, it is proposed according to the invention that the interior trim molding is surrounded with a skin-shaped top sheet. This not only enables a clean Foaming, but also serves to beautify the molded part.
Dabei hat sich als Werkstoff für die Oberlage als besonders geeignet Acrylnitril-Butadien-Styrol erwiesen.It has proven to be particularly suitable as the material for the top layer Acrylonitrile-butadiene-styrene proved.
In der Zeichnung ist die Erfindung anhand eines Ausführungsbeispieles näher veranschaulicht. Sie zeigt einen Querschnitt durch eine Armaturentafel 1, aus dem deren schichtweiser Aufbau erkennbar ist.In the drawing, the invention is based on an exemplary embodiment illustrated in more detail. It shows a cross section through an instrument panel 1, from which their layered structure can be seen.
Formbildendes Hauptteil ist dabei ein Faserstofformpreßkörper 2, wie er heute allgemein für Innenverkleidungszwecke verwendet wird. Die Rückseite des Faserstofformpreßkörpers 2, die bei einem Aufprall einer Person auf die Armaturentafel 1 die Zugzone bildet, ist mit einer als Gewebe ausgebildeten Matte beschichtet, die aus Polyester, Polyamid oder Glasfaser bestehen kann. Diese Matte sorgt für eine wesentliche Stabilitäteverbesserung bei günstigem Verformungsverhalten.The main part forming the shape is a molded fiber molded body 2, such as it is now commonly used for interior trim purposes. The back of the Faserstofformpreßkörpers 2, which in the event of an impact of a person on the dashboard 1 forms the tension zone, is coated with a mat designed as a fabric, which can consist of polyester, polyamide or fiberglass. This mat takes care of a significant improvement in stability with favorable deformation behavior.
Die Vorderseite des Faserstofformpreßkörpers 2 ist mit einer Schaumstoffschicht 4 versehen, die ebenso wie die Rückseite von einer hautförmigen Oberlage 5 aus Acrylnitril-Butadien-Styrol beschichtet ist. Der Faserstofformpreßkörper 2 weist zusätzlich Löcher 6 auf, die es ermöglichen, daß beim Einspritzvorgang zur Bildung der Schaumstoffschicht 4 der Schaumstoff auch an die Rückseite des Faserstofformkörpers 2 gelangt und dort die Verklebung zwischen diesem und der Matte 3 herstellt. LeerseiteThe front of the molded fiber molded body 2 is covered with a foam layer 4 provided, which like the back of a skin-shaped top layer 5 made of acrylonitrile-butadiene-styrene is coated. The molded fiber molded body 2 also has holes 6, which make it possible that during the injection process to form the foam layer 4 of the Foam also reaches the back of the molded fiber body 2 and there the Bonding between this and the mat 3 produces.
