Description

Dachhimmel eines Fahrzeugs mit einer an einem beweglichen Schiebehimmel angeordneten Lichtquelle Headlining of a vehicle with a light source arranged on a movable sliding headlining
Die Erfindung bezieht sich auf einen Dachhimmel eines Fahrzeugs mit einer an einem beweglichen Schiebehimmel angeordneten Lichtquelle, wobei der Dachhimmel ein transparentes Dachhimmelsegment aufweist und der Bereich unterhalb des transparenten Dachhimmelsegments mittels des Schiebehimmels verschließbar ist.The invention relates to a headlining of a vehicle with a light source arranged on a movable sliding headlining, the headlining having a transparent headlining segment and the area below the transparent headlining segment being closable by means of the sliding headlining.
Die Integration von lichttechnischen Systemen zur Optimierung der Lichtverhältnisse im Innenraum eines Fahrzeugs, ausgehend von den Anforderungen der Fahrzeuginsassen, ist ein Thema aktueller Entwicklungen.The integration of lighting systems to optimize the lighting conditions in the interior of a vehicle, based on the requirements of the vehicle occupants, is a topic of current developments.
Zur Beleuchtung des Innenraums eines Fahrzeugs bei Dunkelheit kann beispielsweise im Fahrzeug zusätzlich eine Flächenleuchte angeordnet sein. Flächenleuchten haben durch die Beleuchtung einer großen Fläche eine geringere Neigung zum Wurf von Schatten als punktuelle Lichtquellen. Eine spezielle Ausführung einer Flächenleuchte ist aus der US 5 079 675 bekannt. Die Flächenleuchte hat eine gleichmäßige Lichtverteilung über eine Fläche und dient zur Beleuchtung eines Objektes oder eines Raumes. Die Flächenleuchte weist mindestens eine Scheibe auf, wobei an wenigstens einer Seite der Scheibe eine Lichtquelle angeordnet ist, um welche ein Reflektionskörper angeordnet ist, der das Licht in die Scheibe reflektiert. In der Scheibe sind geneigte Reflektionsflachen vorgesehen, die parallel einfallendes Licht um einen vorgegebenen Winkel reflektieren, so dass das Licht in eine Vorzugsrichtung gerichtet abgestrahlt wird. Auf der gegenüberliegenden Seite der Vorzugsrichtung der transparenten Scheibe ist eine Reflektionsscheibe angeordnet, die das hierauf fallende Licht in die gewünschte abzustrahlende Richtung reflektiert, so dass eine gleichmäßige und intensive Lichtabstrahlung in eine Vorzugsrichtung erreicht wird.To illuminate the interior of a vehicle in the dark, for example, an area light can additionally be arranged in the vehicle. Area lights have less tendency to cast shadows than spot light sources due to the lighting of a large area. A special version of a surface light is known from US 5 079 675. The area light has a uniform light distribution over a surface and is used to illuminate an object or a room. The surface luminaire has at least one pane, a light source being arranged on at least one side of the pane, around which a reflection body is arranged, which reflects the light into the pane. Inclined reflection surfaces are provided in the pane, which reflect parallel incident light by a predetermined angle, so that the light is emitted in a preferred direction. On the opposite side of the preferred direction A transparent disc is arranged, which reflects the light falling on it in the desired direction to be emitted, so that a uniform and intensive light radiation in a preferred direction is achieved.
Außerdem ist in der DE 199 02 244 AI ein Dachhimmel eines Fahrzeugs mit einer Flächenleuchte beschrieben. Der Dachhimmel umfasst ein transparentes Dachelement, wobei der Bereich unterhalb des transparenten Dachelementes mit einem Schiebehimmel verschließbar ist. Die Flächenleuchte ist am Schiebehimmel auf der Fahrzeuginnenseite angebracht und wird beim Bewegen des Schiebehimmels mitbewegt.In addition, DE 199 02 244 AI describes a headlining of a vehicle with a surface light. The headliner comprises a transparent roof element, the area below the transparent roof element being closable with a sliding headliner. The area light is attached to the roof lining on the inside of the vehicle and is also moved when the roof lining is moved.
Die Energieversorgung der Flächenleuchte erfolgt hierbei in der Regel aus dem elektrischen Bordnetz über elektrische Leitungen, die mit dem fahrbaren Schiebehimmel mitbewegt werden. Die Leitungslänge muss dabei so ausreichend sein, dass ein Abreißen der Verbindung während eines Offnungs- oder Schließvorgangs des Schiebehimmels vermieden wird. Außerdem wird genügend Stauraum für die elektrischen Leitungen und Leitungskanäle für eine geeignete Führung derselbigen benötigt .The area light is usually supplied with energy from the on-board electrical system via electrical lines that are moved with the movable sliding headliner. The cable length must be sufficient to prevent the connection from being torn off during an opening or closing process of the headliner. Sufficient storage space for the electrical lines and line ducts is also required for a suitable guidance of the same.
Der Erfindung liegt nun die Aufgabe zugrunde, einen Dachhimmel eines Fahrzeugs mit einer an einem beweglichen Schiebehimmel angeordneten Lichtquelle anzugeben, der eine einfache, platzsparende und zuverlässige Stromzufuhr für die Flächenleuchte gewährleistet.The invention is based on the object of specifying a headliner of a vehicle with a light source arranged on a movable sliding headliner, which ensures a simple, space-saving and reliable power supply for the area light.
Die Aufgabe wird gelöst durch die Merkmalskombination des Patentanspruchs 1.The object is achieved by the combination of features of patent claim 1.
Beim Dachhimmel eines Fahrzeugs mit einer an einem beweglichen Schiebehimmel angeordneten Lichtquelle, wobei der Dachhimmel ein transparentes Dachhimmelsegment aufweist und der Bereich unterhalb des transparenten Dachhimmelsegments mittels des Schiebehimmels abdeckbar bzw. verschließbar ist, weist der Schiebehimmel mit der Lichtquelle elektrisch verbundene erste Kontaktmittel auf und der Dachhimmel trägt zweite elektrische Kontaktmittel, welche extern an eine Energiequelle elektrisch angeschlossen sind (z.B. an ein Kraftfahrzeug-Bordnetz) , wobei bei geschlossenem Schiebehimmel die ersten und zweiten Kontaktmittel für eine Energieversorgung der Lichtquelle elektrisch leitend miteinander verbunden sind.In the headlining of a vehicle with a light source arranged on a movable sliding headlining, the headlining having a transparent headlining segment and the area below the transparent headlining segment being coverable or closable by means of the sliding headliner, the headliner has first contact means electrically connected to the light source and the headliner carries second electrical contact means which are electrically connected externally to an energy source (for example to a vehicle electrical system), the first and second contact means for supplying energy to the light source when the headliner is closed are electrically connected together.
Die mit dem Schiebehimmel vorzugsweise starr verbundenen ersten elektrischen Kontaktmittel werden während eines Schließvorganges so bewegt, dass bei Erreichen der Endlage des Schiebehimmels eine elektrisch leitende Verbindung mit den am Dachhimmel fixierten zweiten elektrischen Kontaktmitteln besteht. Beide Bauelemente sind vorzugsweise metallisch ausgeführt und somit elektrisch leitfähig. Durch diese Art der Kontaktierung kann auf eine Mitführung von elektrischen Leitungen während der Bewegung des Schiebehimmels oder auf Schleifkontakte verzichtet werden. Eine einfache und zuverlässige Stromversorgung der Lichtquelle ist somit gewährleistet.The first electrical contact means, which are preferably rigidly connected to the sliding headliner, are moved during a closing process such that when the end position of the sliding headliner is reached, there is an electrically conductive connection with the second electrical contact means fixed to the headliner. Both components are preferably metallic and thus electrically conductive. This type of contact eliminates the need to carry electrical cables during the movement of the sliding headliner or sliding contacts. This guarantees a simple and reliable power supply for the light source.
Vorzugsweise sind die zweiten elektrischen Kontaktmittel als mindestens ein Stiftkontakt ausgeführt. In dieser Ausfuhrungsform fährt der Schiebehimmel in seiner Endlage auf den Stiftkontakt. Es wird eine besonders stabile Kontaktierung durch ein Ineinandergreifen der elektrischen Kontaktmittel erreicht, die auch durch eine starke Erschütterung des Fahrzeugs nicht destabilisiert wird.The second electrical contact means are preferably designed as at least one pin contact. In this embodiment, the sliding headliner moves to the pin contact in its end position. A particularly stable contact is achieved by intermeshing the electrical contact means, which is not destabilized even by a strong vibration of the vehicle.
Insbesondere können die ersten elektrischen Kontaktmittel in Schließrichtung im vorderen seitlichen Endbereich des Schiebehimmels angeordnet sein. Mit dieser Ausgestaltung wird eine Anordnung der zweiten elektrischen Kontaktmittel im Bereich der Führungsschienen des Fahrzeugshimmels vermieden. Die zweiten elektrischen Kontaktmittel befinden sich daher nicht im Bereich des Bewegungsmechanismus des Schiebehimmels, wodurch eine stabile Befestigung der elektrischen Kontaktmittel erreicht wird.In particular, the first electrical contact means can be arranged in the closing direction in the front lateral end region of the sliding headliner. With this configuration, an arrangement of the second electrical contact means in the region of the guide rails of the vehicle headlining is avoided. The second electrical contact means are therefore not in the area of the moving mechanism of the sliding headliner, whereby a stable attachment of the electrical contact means is achieved.
In einer weiteren Ausgestaltung der Erfindung ist die Lichtquelle als Flächenleuchte ausgeführt, wodurch eine besonders günstige Ausleuchtung des Fahrzeuginnenraums erreicht wird.In a further embodiment of the invention, the light source is designed as a surface light, whereby particularly favorable illumination of the vehicle interior is achieved.
Insbesondere ist den zweiten elektrischen Kontaktmitteln ein Spannungswandler zum Transformieren der Bordnetzspannung (z.B. 14 V oder 42 V) vorgeschaltet. Bei einer Flächenleuchte in Ausgestaltung einer Elektrolumineszenzfolie wird die Spannung beispielsweise auf 110 V hochtransformiert. Dadurch wird eine Übertragung hoher elektrischer Spannungen im Dachbereich ermöglicht.In particular, the second electrical contact means is preceded by a voltage converter for transforming the vehicle electrical system voltage (e.g. 14 V or 42 V). In the case of a surface light in the form of an electroluminescent film, the voltage is stepped up to 110 V, for example. This enables the transmission of high electrical voltages in the roof area.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen wiedergegeben.Further advantageous embodiments of the invention are given in the subclaims.
Die Erfindung wird anhand mehrerer Ausführungsbeispiele in den Figuren näher erläutert. Es zeigen:The invention is explained in more detail with reference to several exemplary embodiments in the figures. Show it:
FIG 1 einen Ausschnitt aus einer Dachkonstruktion eines Fahrzeugs mit einem Schiebehimmel in Draufsicht in schematischer Darstellung; und1 shows a detail of a roof structure of a vehicle with a sliding roof in a top view in a schematic representation; and
FIG 2 einen Dachhimmel in einer schematischen Explosionsdarstellung .2 shows a headliner in a schematic exploded view.
Der in der FIG 1 dargestellte Ausschnitt einer Dachkonstruktion eines Fahrzeugs umfasst einen Dachhimmel 2 mit Fensterelementen 4 und Trägerelementen 6. Im zentralen Bereich des Dachhimmels 2 ist ein Führungsrahmen 8 für einen Schiebehimmel 10 angeordnet. Ein transparentes Dachhimmelsegment 40 verschließt himmelseitig den Dachhimmel 2. Beim transparenten Dachhimmelsegment 40 kann es sich beispielsweise um ein Glasdach oder um ein transparentes Schiebedach handeln.The section of a roof structure of a vehicle shown in FIG. 1 comprises a headliner 2 with window elements 4 and support elements 6. A guide frame 8 for a sliding headliner 10 is arranged in the central region of the headliner 2. A transparent headlining segment 40 closes the headlining 2 on the sky side. The transparent headlining segment 40 can for example, a glass roof or a transparent sliding roof.
Der Fuhrungsrahmen 8 weist seitliche, im wesentlichen parallel zur Längsachse des Fahrzeugs verlaufende Führungsschienen 12 auf, in welchen der Schiebehimmel 10 beweglich gelagert ist. Im geschlossenen Zustand deckt der Schiebehimmel 10 das transparente Dachhimmelsegment 40 vollständig ab, so dass kein natürliches Licht von außen durch das transparente Dachhimmelsegment 40 in den Fahrzeuginnenraum gelangen kann.The guide frame 8 has lateral, essentially parallel to the longitudinal axis of the vehicle guide rails 12, in which the sliding headliner 10 is movably mounted. In the closed state, the sliding headliner 10 completely covers the transparent headlining segment 40, so that no natural light can enter the vehicle interior through the transparent headlining segment 40.
Am Schiebehimmel 10 ist innenraumseitig eine Lichtquelle 30 angeordnet, welche in diesem Ausführungsbeispiel als Flächenleuchte in Ausgestaltung einer Elektrolumineszenzfolie ausgeführt ist. Die Flächenleuchte deckt in diesem Ausführungsbeispiel bei geschlossenem Schiebehimmel 10 nahezu den gesamten Bereich des transparenten DachhimmelSegments 40 ab. Es sind aber auch Flächenleuchten mit einer kleineren Flächenbelegung denkbar. Die Flächenleuchte kann auch eine wie in der US 5 079 675 beschriebene Ausgestaltung aufweisen.A light source 30 is arranged on the interior of the sliding liner 10, which in this exemplary embodiment is designed as a surface light in the form of an electroluminescent film. In this exemplary embodiment, when the sliding headliner 10 is closed, the surface light covers almost the entire area of the transparent headlining segment 40. Area lights with a smaller area coverage are also conceivable. The surface light can also have a configuration as described in US Pat. No. 5,079,675.
Der Schiebehimmel 10 weist mit der Flächenleuchte über eine elektrische Leitung 14 verbundene erste Kontaktmittel 16 auf, die in Schließrichtung 32 des Schiebehimmels 10 im vorderen seitlichen Endbereich auf der Oberseite des Schiebehimmels 10 angeordnet sind. Die Öffnungsrichtung 34 des Schiebehimmels 10 ist der Schließrichtung 32 entgegengesetzt.The sliding headliner 10 has first contact means 16 connected to the surface light via an electrical line 14, which are arranged in the closing direction 32 of the sliding headliner 10 in the front lateral end region on the top of the sliding headliner 10. The opening direction 34 of the sliding headliner 10 is opposite to the closing direction 32.
Am Fuhrungsrahmen 8 des Schiebehimmels 10 sind über die beiden Anschlüsse 36, 38 mit dem elektrischen Bordnetz elektrisch leitend verbundene zweite Kontaktmittel 18 derart angeordnet, dass bei geschlossenem Schiebehimmel 10 die Kontaktmittel 16, 18 zur Energieversorgung der Flächenleuchte elektrisch leitend miteinander verbunden sind. Diese Anordnung der Kontaktmittel 16, 18 im vorderen Bereich ermöglichen eine einfache Montage der zweiten elektrischen Kontaktmittel 16 neben der Führungsschiene 12.Second contact means 18, which are electrically conductively connected to the on-board electrical system, are arranged on the guide frame 8 of the sliding headliner 10 in such a way that when the sliding headliner 10 is closed, the contact means 16, 18 are electrically conductively connected to one another for supplying energy to the surface light. This arrangement of the contact means 16, 18 in the front area enable simple mounting of the second electrical contact means 16 next to the guide rail 12.
Die zweiten elektrischen Kontaktmittel 18 sind auf einem am Fuhrungsrahmen 8 fixierten Plattenelement 24 angeordnet . Das Führungselement 22 des Aufnahmeelements 20 des Schiebehimmels 10 befindet sich in seiner Endlage im Endbereich der Führungsschiene 12. Die Kontaktmittel 18 sind somit dem Endbereich der Führungsschiene 12 benachbart angeordnet .The second electrical contact means 18 are arranged on a plate element 24 fixed to the guide frame 8. The guide element 22 of the receiving element 20 of the sliding headliner 10 is in its end position in the end region of the guide rail 12. The contact means 18 are thus arranged adjacent to the end region of the guide rail 12.
Die zweiten elektrischen Kontaktmittel 18 sind in diesem Ausführungsbeispiel als zwei Stiftkontakte ausgeführt, die eine Plus- bzw. Minusbelegung aufweisen. Ebenfalls möglich ist eine Ausfuhrungsform mit nur einem Stiftkontakt, der die Plus- und Minusbelegung in sich vereint. Der Schiebehimmel 10 fährt in seiner Endlage auf die elektrischen Kontaktmittel 18 und umfasst diese in einer rastenden Stellung, wodurch eine stabile elektrische Verbindung mit geringem Platzaufwand bei geschlossenem Schiebehimmel 10 gewährleistet ist. Auf zusätzlich mitzuführende elektrische Leitungen zur Stromversorgung des Schiebehimmels 10 kann verzichtet werden. Zur besseren Veranschaulichung ist der Schiebehimmel 10 in der FIG 1 in einem leicht geöffneten Zustand, angedeutet durch die beiden Doppelpfeile 40, dargestellt. In nicht weiter dargestellten Ausführungsbeispielen können die beiden elektrischen Kontaktmittel auch an anderer Stelle am Schiebehimmel bzw. am Fuhrungsrahmen angebracht sein. Es muss lediglich der elektrische Kontakt zwischen den beiden Kontaktmitteln im geschlossenen Zustand des Schiebehimmels gesichert sein.In this exemplary embodiment, the second electrical contact means 18 are designed as two pin contacts which have a plus or minus assignment. An embodiment with only one pin contact, which combines the plus and minus assignment, is also possible. The sliding headliner 10 moves in its end position onto the electrical contact means 18 and encompasses them in a latching position, as a result of which a stable electrical connection is ensured with little space requirement when the sliding headliner 10 is closed. There is no need for additional electrical lines to be carried to power the sliding headliner 10. For better illustration, the sliding headliner 10 is shown in FIG. 1 in a slightly open state, indicated by the two double arrows 40. In exemplary embodiments not shown, the two electrical contact means can also be attached elsewhere on the sliding headliner or on the guide frame. It is only necessary to ensure the electrical contact between the two contact means when the headliner is closed.
Den zweiten Kontaktmitteln 18 ist ein nicht weiter dargestellter Spannungswandler zum Transformieren der Bordnetzspannung vorgeschaltet. Bei Verwendung einer Elektrolumineszenzfolie als Flächenleuchte wird die Bordnetzspannung auf 110 V hochtransformiert. Mit der vorliegenden Anordnung zur Energieversorgung der am Schiebehimmel 10 des Fahrzeugs angeordneten Flächenleuchte ist somit eine Übertragung einer hohen elektrischen Spannung, die für die Flächenleuchte erforderlich ist, gegeben.The second contact means 18 is preceded by a voltage converter (not shown) for transforming the vehicle electrical system voltage. If an electroluminescent film is used as an area light, the vehicle electrical system voltage is stepped up to 110 V. With the present arrangement for power supply on Sliding headliner 10 of the vehicle-mounted surface light is thus a transmission of a high electrical voltage, which is required for the surface light.
Bei geschlossenem Schiebehimmel 10 kann die elektrische Verschaltung so ausgelegt sein, dass die Flächenleuchte automatisch eingeschaltet wird oder über ein Bedienelement im Fahrzeuginnenraum eingeschaltet wird. Ein solches Bedienelement kann beispielsweise ebenfalls im Dachhimmel 2 des Fahrerbereichs oder im zugänglichen Sitzbereich der Mitfahrer sowohl im vorderen als auch im hinteren Bereich des Fahrzeugs angeordnet sein.When the sliding headliner 10 is closed, the electrical connection can be designed such that the surface light is switched on automatically or is switched on via an operating element in the vehicle interior. Such an operating element can, for example, also be arranged in the headlining 2 of the driver's area or in the accessible seating area of the passengers both in the front and in the rear area of the vehicle.
Auf dem Schiebehimmel 10 sind im Randbereich Aufnahmeelemente 20 angeordnet, die mit Fuhrungselementen 22 in die Führungsschienen 12 eingreifen, wodurch die Fahrbarkeit des Schiebehimmels 10 ermöglicht wird.On the sliding headliner 10, receiving elements 20 are arranged in the edge area, which engage with guide elements 22 in the guide rails 12, thereby making the sliding headliner 10 drivable.
Auf der dem transparenten Dachhimmelsegment 40 abgewandten Seite des Schiebehimmels 10 ist eine zwischen verschiedenen lichtdurchlässigen Zuständen schaltbare Scheibe 42 angeordnet. Der Schiebehimmel 10 ist somit zwischen dem transparenten Dachhimmelsegment 40 und der schaltbaren Scheibe 42 angeordnet. Die schaltbare Scheibe 42 ist mechanisch unabhängig vom Schiebehimmel 10 derart angeordnet, dass der Schiebehimmel 10 mit der Flächenleuchte unabhängig von der schaltbaren Scheibe 42 bewegt werden kann. Die Scheibe 42 ist vorzugsweise zwischen lichtdurchlässig und teillichtdurchlässig schaltbar. Die Umschaltung wird beispielsweise über ein Bedienelement im Fahrzeuginnenraum getätigt. Bei geöffnetem Schiebehimmel 10 und auf Lichtdurchlässigkeit geschalteter Scheibe 42 kann natürliches Licht durch das transparente Dachhimmelsegment 40 in den Fahrzeuginnenraum einfallen, als wäre nur das transparente Dachhimmelsegment 40 vorhanden. Bei geöffnetem Schiebehimmel 10 und bei auf Teillichtdurchlässigkeit geschalteter Scheibe 42 wird das durch das transparente Dachhimmelsegment 40 einfallende Licht von der Scheibe 42 teilweise zurückreflektiert. Das Licht gelangt stark gestreut in den Fahrzeuginnenraum.On the side of the sliding headliner 10 facing away from the transparent headliner segment 40, a disc 42 which can be switched between different transparent states is arranged. The sliding roof lining 10 is thus arranged between the transparent headlining segment 40 and the switchable pane 42. The switchable pane 42 is arranged mechanically independently of the sliding headliner 10 in such a way that the sliding headliner 10 can be moved independently of the switchable pane 42 with the surface light. The disk 42 can preferably be switched between translucent and partially translucent. The switchover is carried out, for example, via an operating element in the vehicle interior. When the sliding roof lining 10 is open and the pane 42 is switched to light transmission, natural light can enter the vehicle interior through the transparent roof lining segment 40, as if only the transparent roof lining segment 40 were present. When the sliding headliner 10 is open and the pane 42 is switched to partial light transmission, the light incident through the transparent headlining segment 40 is partially reflected back by the pane 42. The light enters the vehicle interior in a highly scattered manner.
Bei geschlossenem Schiebehimmel 10 mit angeschalteter Flächenleuchte und auf Lichtdurchlässigkeit geschalteter Scheibe 42 wird das Licht der Flächenleuchte durch die Scheibe 42 nicht verändert . Bei geschlossenem Schiebehimmel 10 mit eingeschalteter Flächenleuchte und einer teillichtdurchlässig geschalteten Scheibe 42 gelangt das Licht der Flächenleuchte stark gestreut in den Fahrzeuginnenraum.When the sliding roof lining 10 is closed with the surface light switched on and the pane 42 switched to translucency, the light of the surface light is not changed by the pane 42. When the sliding headliner 10 is closed with the surface light switched on and a pane 42 that is switched to be partially translucent, the light from the surface light reaches the vehicle interior in a highly scattered manner.
FIG 2 zeigt einen Ausschnitt des Dachhimmels 2 in einer schematischen Explosionsdarstellung. Der Dachhimmel 2 ist teilweise mit Solarzellen bzw. mit Photovoltaikzellen 44 belegt, die elektrische Verbraucher oder dergleichen (beispielsweise Bordnetzbatterie) mit Energie versorgen. Auf der dem Fahrzeuginnenraum zugewandten Seite des transparenten DachhimmelSegments 40 ist der Fuhrungsrahmen 8 des Schiebehimmels 10 angeordnet. Die Führungselemente 22 der Aufnahmeelemente 20 des Schiebehimmels 10 greifen im zusammengesetzten Zustand des Dachhimmels 2 in die Führungsschienen 12 des Führungsrahmens 8.2 shows a section of the headliner 2 in a schematic exploded view. The roof liner 2 is partially covered with solar cells or with photovoltaic cells 44, which supply electrical consumers or the like (for example an on-board electrical system battery) with energy. The guide frame 8 of the sliding headlining 10 is arranged on the side of the transparent headlining segment 40 facing the vehicle interior. In the assembled state of the headliner 2, the guide elements 22 of the receiving elements 20 of the sliding headliner 10 engage in the guide rails 12 of the guide frame 8.
Auf der dem transparenten Dachhimmelsegment 40 abgewandten Seite des Schiebehimmels 10 ist die zwischen verschiedenen lichtdurchlässigen Zuständen schaltbare Scheibe 42 angeordnet. Die Fläche der Scheibe 42 deckt den Schiebehimmel 10 in seinem geschlossenen Zustand vollständig ab. On the side of the sliding headliner 10 facing away from the transparent headliner segment 40, the pane 42, which can be switched between different transparent states, is arranged. The surface of the pane 42 completely covers the sliding roof 10 in its closed state.
