Description

Dachreling für ein Kraftfahrzeug  Roof rail for a motor vehicle

Die vorliegende Erfindung betrifft eine Dachreling für ein Kraftfahrzeug mit einer Tragstruk tur zur Verbindung der Dachreling mit dem Kraftfahrzeug, und mit einer die Tragstruktur überdeckenden Dekorblende, wobei die Dekorblende an der Tragstruktur befestigt ist. The present invention relates to a roof rail for a motor vehicle with a Tragstruk tur for connecting the roof rail to the motor vehicle, and with a support structure covering the decorative panel, wherein the decorative panel is attached to the support structure.

Eine gattungsgemäße Dachreling kann der Offenlegungsschrift DE 10 2014 220 630 A1 entnommen werden. Diese Dachreling ist zur Aufnahme von Leuchtmitteln vorgesehen. Nachteilig an dieser vorbekannten Dachreling ist, dass die Leuchtmittel ihr Licht durch eine Ausnehmung in der Dekorblende nach außen hin emittieren. Diese Ausnehmungen sind durch transparente Abdeckungen verschlossen. Diese sind für den Benutzer oder Betrach ter des Kraftfahrzeuges von außen gut sichtbaren und stellen eine gravierende ästhetische Beeinträchtigung dar. Im Stand der Technik ist darüber hinaus bekannt, Sensorelemente in den Stoßfängerverkleidungen des Kraftfahrzeuges zu integrieren. Problematisch hierbei ist, dass die Stoßfängerverkleidung an einer relativ niedrigen Position des Kraftfahrzeuges an geordnet sind und die Sensorelemente insofern einen eingeschränkten Erfassungsbereich aufweisen. A generic roof rail can be found in the published patent application DE 10 2014 220 630 A1. This roof rail is provided for receiving bulbs. A disadvantage of this known roof rail is that the bulbs emit their light through a recess in the decorative panel to the outside. These recesses are closed by transparent covers. These are clearly visible to the user or obra ter of the motor vehicle from the outside and represent a serious aesthetic impairment. In the prior art is also known to integrate sensor elements in the bumper panels of the motor vehicle. The problem here is that the bumper fascia are arranged at a relatively low position of the motor vehicle and the sensor elements insofar have a limited detection range.

Aufgabe der vorliegenden Erfindung ist es daher eine gattungsgemäßes Dachreling dahin gehend zu verbessern, dass diese ein ästhetisch ansprechenderes und dem üblichen ent sprechendes Erscheinungsbild aufweist und zudem Sensorelemente einen vergrößerten Er fassungsbereich aufweisen. Object of the present invention is therefore to improve a generic roof railing going there that this has a more aesthetically pleasing and the usual ent speaking appearance and also sensor elements have an enlarged He fassungsbereich.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Dachreling für ein Kraftfahrzeug mit: This object is achieved by a roof rail for a motor vehicle with:

The sensor element is likewise integrated into the support structure in a space-saving manner and is even better protected by the support structure.

Die Dekorblende kann aus einem Polymermaterial hergestellt sein, wobei die Transmissivi- tät der Dekorblende so gewählt ist, dass diese eine ausreichend niedrige Transmissivität für natürliches Umgebungslicht aufweist, sodass das Sensorelement nach außen hin für den Betrachter verdeckt ist, wobei das Polymermaterial gleichzeitig eine hohe Transmissivität für die genutzte Wellenlänge oder die genutzten Wellenlängen des Sensorelements auf weist. The decorative panel may be made of a polymeric material, wherein the transmissivity of the decorative panel is selected to have a sufficiently low transmissivity for natural ambient light such that the sensor element is concealed to the outside of the viewer, the polymer material simultaneously having high transmissivity for the wavelength used or the wavelengths of the sensor element used has.

Die Transmissivität der Dekorblende kann über eine Beschichtung auf dem Material der De korblende und/oder durch eine Folie auf dem Material der Dekorblende und/oder durch Licht absorbierende Zusätze zu dem Material der Dekorblende eingestellt sein. Bei der Be schichtung kann es sich insbesondere um eine metallische Beschichtung (zum Beispiel eine CVD- oder PVD-Beschichtung) handeln. Als Licht absorbierende Zusätze eignet sich beispielsweise Kohlenstoffruß. Die Tragstruktur kann aus einem faserverstärkten Polymermaterial oder aus einem metalli schen Werkstoff oder aus einem metall verstärkten Polymermaterial bestehen. Ein Metall verstärktes Polymermaterial kann insbesondere ein sogenanntes Hybrid-Bauteil aus einem vorgeformten Metallelement und einer auf das Metallelement aufgebrachten (zum Beispiel im Spritzguss) Polymerschicht oder Polymerverrippung handeln. Ein faserverstärktes Poly mermaterial kann insbesondere ein Organoblech oder einen Flechtschlauch aus den Ver stärkungsfasern umfassen. The transmissivity of the decorative panel can be adjusted by means of a coating on the material of the decorative panel and / or by a film on the material of the decorative panel and / or by light-absorbing additives to the material of the decorative panel. The coating may in particular be a metallic coating (for example a CVD or PVD coating). As light-absorbing additives, for example carbon black is suitable. The support structure may consist of a fiber-reinforced polymer material or of a metallic material or of a metal-reinforced polymer material. A metal-reinforced polymer material may, in particular, be a so-called hybrid component of a preformed metal element and a polymer layer or polymer ribbing (for example by injection molding) applied to the metal element. A fiber-reinforced polymer material may in particular comprise an organic sheet or a braided hose made of reinforcing fibers.
