Abstract
Description
Die Erfindung betrifft ein Innenverkleidungsteil, für ein Kraftfahrzeug, sowie ein Verfahren zur Herstellung eines Innenverkleidungsteils für ein Kraftfahrzeug.The invention relates to an interior trim part, for a motor vehicle, and to a method for producing an interior trim part for a motor vehicle.
Aus der
Bei der Herstellung derartiger Baugruppen müssen zuerst die einzelnen Teile der Dekorhaut zueinander exakt ausgerichtet werden bevor das Zusammennähen erfolgen kann. Nach dem Zusammennähen muss weiterhin genau auf die Ausrichtung der Dekorhaut zu dem Trägerteil geachtet werden, damit eine korrekte Ausrichtung der Ziernaht zu dem Bauteil erfolgen kann. Ein Nachteil dieses Verfahrens ist in dem erhöhten Positionieraufwand während des Fertigungsprozess zu sehen, der zu einer Verlängerung der Fertigungsdauer und damit zu erhöhten Kosten führt.In the production of such assemblies, the individual parts of the decorative skin must first be exactly aligned with each other before the sewing can be done. After sewing together, attention must continue to pay close attention to the orientation of the decorative skin to the support member, so that a correct alignment of the decorative seam can be done to the component. A disadvantage of this method is to be seen in the increased positioning effort during the manufacturing process, which leads to an extension of the production time and thus to increased costs.

Die vorliegende Erfindung bietet den Vorteil, dass die Ziernähte und/oder die Befestigungsnähte erst nachdem das Bauteil mit der Dekorschicht versehen wurde aufgenäht werden. In einem ersten Schritt erfolgt das Aufbringen einer Dekorschicht auf ein Trägerteil. Dies kann mittels Kaschieren oder Laminieren erfolgen. In einer zweiten Alternativ hierzu kann die Dekorschicht auch mit dem Trägerteilmaterial hinterspritzt werden, wobei zunächst die Dekorschicht in ein Spritzwerkzeug eingebracht und in ihre spätere Form überführt wird. Danach erfolgt das Hinterspritzen mit der Dekorschicht mit einem Material zur Herstellung des Trägerteils. In einer dritten Alternative kann das Trägerteil durch Heizpressen erzeugt werden. Dabei ist es auch denkbar unmittelbar, d. h. in einem Arbeitsschritt einen Verbund aus Dekorschicht und Trägerteil durch Heizpressen zu bilden.The present invention offers the advantage that the decorative seams and / or the fastening seams are sewn on only after the component has been provided with the decorative layer. In a first step, the application of a decorative layer to a carrier part. This can be done by laminating or laminating. In a second alternative to this, the decorative layer can also be back-injected with the carrier part material, wherein first the decorative layer is introduced into an injection mold and converted into its later form. Thereafter, the back molding with the decorative layer with a material for the production of the carrier part. In a third alternative, the carrier part can be produced by hot pressing. It is also conceivable directly, d. H. to form in one step a composite of decorative layer and carrier part by heating presses.
Anschließend erfolgt das Erzeugen der Ziernähte mittels Durchnähen, durch die Dekorschicht und das Trägerteil. Dadurch kann das Bestücken des Werkzeugs mit der Dekorschicht vereinfacht werden, da die Ziernaht nicht ausgerichtet werden muss. Gleichzeitig wird damit die Qualitätsanmutung gesteigert, da der Ziernahtverlauf und die Ziernahtausrichtung stets gleich bleiben. Die zweite Ausführungsform des Herstellungsprozess bietet den Vorteil, dass auf den im Stand der Technik notwendigen Prozessschritt des Abdichtens beim Hinterspritzverfahren verzichtet werden kann. Dies ergibt sich daraus, dass erst nach dem Hinterspritzen die Naht erzeugt wird und somit Löcher in der Dekorschicht erst nach dem dichtigkeitskritischen Hinterspritzprozess entstehen. Ferner können durch unterschiedliche Nutformen in dem Trägerteil eine Vielzahl verschiedener Ziernahtmuster erzeugt werden.Subsequently, the decorative seams are produced by means of sewing, through the decorative layer and the carrier part. As a result, the loading of the tool with the decorative layer can be simplified because the decorative seam does not have to be aligned. At the same time the quality impression is increased, since the decorative stitching and the decorative seam alignment always remain the same. The second embodiment of the manufacturing process offers the advantage that it is possible to dispense with the process step of sealing in the back-injection process which is necessary in the prior art. This results from the fact that the seam is produced only after the back molding and thus holes are formed in the decorative layer only after the impermeability critical injection molding process. Furthermore, a variety of different decorative seam patterns can be produced by different groove shapes in the carrier part.
