Interieur-Bauteil eines Fahrzeugs  Interior component of a vehicle
Beschreibung description
Vorliegende Erfindung betrifft ein Interieur-Bauteil eines Fahrzeugs, ein Fahrzeug mit dem Interieur-Bauteil sowie ein Verfahren zur Herstellung des Interieur- Bauteils. The present invention relates to an interior component of a vehicle, a vehicle with the interior component and a method for producing the interior component.
Aus dem Stand der Technik sind unterschiedliche beheizbare Interieur-Bauteile bekannt. Im Regelfall werden diese Bauteile beheizt, da sie vom Fahrer berührt werden und dabei eine angenehme Oberflächentemperatur aufweisen sollen. Insbesondere erfolgt solch eine Beheizung von Interieur-Bauteilen bspw. bei Armlehnen oder Türverkleidungen. Dabei werden zwischen dem steifen Träger des Interieur-Bauteils und der oben liegenden Dekorschicht verschiedene Schaumstoffschichten verwendet. Zwischen diesen Schaumstoffschichten kann die entsprechende Heizschicht angeordnet werden. Dieser Schichtaufbau führt im Regelfall jedoch zu einem relativ dick bauenden Interieur-Bauteil. Different heatable interior components are known from the prior art. As a rule, these components are heated because they are touched by the driver and should have a pleasant surface temperature. In particular, such heating of interior components takes place, for example, in armrests or door panels. Different foam layers are used between the rigid support of the interior component and the decorative layer on top. The corresponding heating layer can be arranged between these foam layers. However, this layer structure usually leads to a relatively thick interior component.
Es ist Aufgabe der vorliegenden Erfindung, ein Interieur-Bauteil für ein Fahrzeug anzugeben, dass bei einfachem Aufbau möglichst dünn bauend ist. Des Weiteren soll sich die Heizung im Interieur-Bauteil nicht an der Oberfläche abzeichnen und es soll eine möglichst hohe Erwärmung des Interieur-Bauteils möglich sein, ohne dass sich dabei eine Abzeichnung ergibt oder die Schichten sich voneinander lösen. It is an object of the present invention to provide an interior component for a vehicle that is as thin as possible with a simple construction. Furthermore, the heating in the interior component should not be visible on the surface and the interior component should be heated as much as possible without being marked or the layers becoming detached from one another.
Die Lösung dieser Aufgabe erfolgt durch die Merkmale der unabhängigen Ansprüche. Die abhängigen Ansprüche haben vorteilhafte Ausgestaltungen der Erfindung zum Gegenstand. This object is achieved by the features of the independent claims. The dependent claims have advantageous refinements of the invention.
Damit wird die Aufgabe gelöst durch ein Interieur-Bauteil eines Fahrzeugs. Das Fahrzeug ist insbesondere ein Straßenfahrzeug. Allerdings kann das Interieur- Bauteil auch in anderweitigen Fahrzeugen, bspw. Wasser- oder Luftfahrzeugen verwendet werden. The task is thus solved by an interior component of a vehicle. The vehicle is in particular a road vehicle. However, the interior Component can also be used in other vehicles, such as water or aircraft.
Das Interieur-Bauteil umfasst eine Trägerschicht und eine Dekorschicht. Die Dekorschicht bildet die sichtbare und berührbare Oberfläche des Interieur- Bauteils. Die nach außen weisende Seite der Dekorschicht ist bspw. aus The interior component comprises a carrier layer and a decorative layer. The decorative layer forms the visible and touchable surface of the interior component. The outward-facing side of the decorative layer is made, for example
Kunststoff, Leder, Kunstleder, Textil oder Holz gebildet. Plastic, leather, synthetic leather, textile or wood are formed.
Des Weiteren umfasst das Interieur-Bauteil eine Abstandsschicht zwischen der Trägerschicht und der Dekorschicht. Die Abstandsschicht ist dabei in direktem Kontakt mit der Dekorschicht. Die Abstandsschicht ist vorzugsweise weicher ausgebildet als die Dekorschicht und/oder die Trägerschicht. Die Trägerschicht ist insbesondere aus einem harten Kunststoff gefertigt. Dieser harte Kunststoff der Trägerschicht ist insbesondere wesentlich härter als das verwendete Material für die Abstandsschicht. Furthermore, the interior component comprises a spacer layer between the carrier layer and the decorative layer. The spacer layer is in direct contact with the decorative layer. The spacer layer is preferably made softer than the decorative layer and / or the carrier layer. The carrier layer is made in particular from a hard plastic. This hard plastic of the carrier layer is in particular much harder than the material used for the spacer layer.
Des Weiteren umfasst das Interieur-Bauteil eine elektrische Heizung mit zumindest einem Heizdraht, der in die Abstandsschicht integriert ist. Durch diese Integration des Heizdrahtes in die Abstandsschicht bedarf es keiner eigenen Schicht zur Aufnahme der Heizung, sondern die ohnehin vorhandene Furthermore, the interior component comprises an electrical heater with at least one heating wire, which is integrated in the spacer layer. This integration of the heating wire into the spacer layer does not require a separate layer to accommodate the heating, but the existing one
Abstandsschicht wird hierfür verwendet. Des Weiteren ermöglicht die Integration des Heizdrahtes in die Abstandsschicht, insbesondere die feste Verbindung des Heizdrahtes mit der Abstandsschicht, dass sich auch bei einer Erwärmung bspw. bis auf 60°, die einzelnen Schichten nicht voneinander lösen. Spacer layer is used for this. Furthermore, the integration of the heating wire in the spacer layer, in particular the firm connection of the heating wire to the spacer layer, makes it possible for the individual layers not to separate from one another even when heated, for example up to 60 °.
Besonders bevorzugt ist vorgesehen, dass zwischen Trägerschicht und It is particularly preferably provided that between the carrier layer and
Dekorschicht ausschließlich die Abstandsschicht angeordnet ist. Diese Decorative layer only the spacer layer is arranged. These
Abstandsschicht ist dabei insbesondere einschichtig ausgebildet. Es gibt somit zwischen dem Träger auf der Unterseite und der Dekorschicht auf der Oberseite lediglich eine Schicht und keine Übereinanderschichtung gleicher oder unterschiedlicher Materialien. The spacer layer is in particular formed in one layer. There is therefore only one layer between the carrier on the underside and the decorative layer on the top and no layering of the same or different materials.
Die Dekorschicht kann auf ihrer nach inne weisenden Seite einen Schaumrücken aufweisen, der fest verbunden ist mit der, die sichtbare Oberfläche darstellenden äußersten Fläche der Dekorschicht. Der Schaumrücken der Dekorschicht sowie der Träger sind beide vorzugsweise mit der einschichtigen Abstandsschicht verklebt. The decorative layer can have a foam backing on its inward-facing side, which is firmly connected to the outermost surface of the decorative layer which represents the visible surface. The foam back of the decorative layer and the carrier are both preferably glued to the single-layer spacer layer.
Der Heizdraht befindet sich vorzugsweise auf der zur Dekorschicht weisenden Seite der Abstandsschicht. Insbesondere ist der Heizdraht auf dieser Seite der Abstandsschicht befestigt und somit integriert. Durch diese Anordnung des Heizdrahtes wird sichergestellt, dass in erster Linie die Dekorschicht und somit die nach außen weisende Seite des Interieur-Bauteils beheizt wird. Bei einer entsprechend dünnen Abstandsschicht ist es auch möglich, den Heizdraht auf der anderen Seite der Abstandsschicht zu befestigen. The heating wire is preferably located on the side of the spacer layer facing the decorative layer. In particular, the heating wire is attached to this side of the spacer layer and thus integrated. This arrangement of the heating wire ensures that primarily the decorative layer and thus the outward-facing side of the interior component is heated. With a correspondingly thin spacer layer, it is also possible to attach the heating wire on the other side of the spacer layer.
Für die Befestigung ist bevorzugt vorgesehen, dass der Heizdraht auf der zur Dekorschicht weisenden Seite der Abstandsschicht aufgenäht ist. For the attachment it is preferably provided that the heating wire is sewn onto the side of the spacer layer facing the decorative layer.
Die Abstandsschicht ist vorzugsweise ein Gewirk. Insbesondere handelt es sich hierbei um ein Abstandsgewirk. Das Abstandsgewirk weist vorzugsweise zwei gegenüberliegende kettengewirkte Warenflächen auf. Diese sind durch The spacer layer is preferably a knitted fabric. In particular, this is a spacer fabric. The spacer fabric preferably has two opposing warp knitted fabric surfaces. These are through
Abstandsfäden, so genannte Pol-Fäden, auf Distanz gehalten. Spacer threads, so-called pile threads, are kept at a distance.
Das Abstandsgewirke weist vorzugsweise eine Stauchhhärte von zumindest 50 kPa, vorzugsweise zumindest 60 kPa auf. Die Stauchhärte wird hier bestimmt an einem Probekörper als Parallelepiped mit Abmessungen 100x100x50 mm und einer Kompression von 40%. The spacer fabric preferably has a compression hardness of at least 50 kPa, preferably at least 60 kPa. The compression hardness is determined here on a specimen as a parallelepiped with dimensions 100x100x50 mm and a compression of 40%.
Durch diese Stauchärte ergibt sich eine leicht eindrückbare Oberfläche, die sich insbesondere eignet für Handschuhkastendeckel, Teile der Instrumententafel oder Teile der Türverkleidung. This compression hardness results in a surface that is easy to push in, which is particularly suitable for glove box lids, parts of the instrument panel or parts of the door trim.
Der beschriebene Schichtaufbau des Interieur-Bauteils eignet sich insbesondere für möglichst dünn bauende Bauteile. Vorzugsweise ist vorgesehen, dass die Dekorschicht eine Dicke von bis zu 3 mm aufweist, vorzugsweise bis zu 2 mm. Des Weiteren ist bevorzugt ist vorgesehen, dass die Abstandsschicht eine Dicke von bis zu 5 mm aufweist. Insbesondere liegt die Dicke der Abstandsschicht bei maximal 3 mm. Die Erfindung umfasst ferner ein Verfahren zur Herstellung eines Interieur- Bauteils wie es soeben beschrieben wurde. Das Verfahren umfasst die folgenden Schritte in gegebener Reihenfolge: Zunächst erfolgt ein Integrieren des The described layer structure of the interior component is particularly suitable for components that are as thin as possible. It is preferably provided that the decorative layer has a thickness of up to 3 mm, preferably up to 2 mm. Furthermore, it is preferably provided that the spacer layer has a thickness of up to 5 mm. In particular, the thickness of the spacer layer is a maximum of 3 mm. The invention further comprises a method for producing an interior component as has just been described.

Diese Verbindung erfolgt insbesondere direkt, also ohne Zwischenschicht, ggf. lediglich mit einem Klebstoff zwischen Dekorschicht und Abstandsschicht. Heating wire on the spacer fabric. The spacer layer is preferably made available as an endless material. The spacer layer is roughly cut before or after the integration. The roughly cut spacer layer is then connected to the decorative layer. This connection takes place in particular directly, that is to say without an intermediate layer, possibly only with an adhesive between the decorative layer and the spacer layer.
Im nächsten Schritt erfolgt ein feines Zuschneiden der Einheit aus In the next step, the unit is cut to size
