Description

[0001] The present invention relates to a motor vehicle with a roof that is at least partially transparent according to the preamble of claim 1.

[0002] From DE 101 40 239 A1, a motor vehicle of the generic type is known with a sunshade device for arrangement under a transparent roof area of ​​the motor vehicle, which has a winding shaft slidably guided on lateral guides, which is adjustable between a storage position, in particular a lowered rear position, and at least one functional position spaced apart from the storage position under the transparent roof area.

[0003] From DE 601 24 162 T2, a device for covering at least one window pane and / or at least one opening of a motor vehicle is known, wherein a covering fabric sheet is used which is movable between a folded and an unfolded position and has at least one support and / or retaining rod in a predetermined shape of said fabric sheet when the latter is unfolded. The said rod(s) are separated from the fabric sheet at least when the latter is folded.

[0004] WO 2006 / 079 332 A1 discloses a blackout device for an opaque pane with a textile web movably mounted between a retracted position and an extended position. The blackout device also has a transverse reinforcement that is rigidly connected to the textile web and can slide between two guide rails arranged on either side of the blackout area.

[0005] From DE 196 49 118 A1, a cladding and insulation curtain for an opening cut into the body of a motor vehicle with interior paneling is known, comprising a panel that is slidably mounted with two lateral edges in two corresponding sliding guides connected to the body. This panel is formed from several slats and has a flexible covering layer on an inner side opposite the body, serving for cladding and insulation. The panel can also be rolled up around an axis by means of a rolling mechanism.

[0006] WO 90 / 00986 A1 describes a sliding roof for a motor vehicle equipped with transverse louvers.

[0007] DE 102 30 444 A1 discloses a sliding wing for closing a body opening of a motor vehicle by means of sealing means connected to a roller shutter rod elements which are movable along parallel lateral guide rails and which can be wound up and unwound from a drum by means of a motor rotary drive for opening and closing the sliding wing.

[0008] A disadvantage of previously known motor vehicles with shading devices is that, especially with large glass surfaces, they often provide a level of darkening that is perceived by the user as insufficient.

[0009] The present invention therefore deals with the problem of providing a shading device for a motor vehicle of the generic type, which enables comfortable large-area shading and shielding of an interior of the motor vehicle from its surroundings.

[0010] This problem is solved according to the invention by the subject matter of independent claim 1. Advantageous embodiments are the subject matter of the dependent claims.

[0011] The present invention is based on the general concept of providing a shading device for a motor vehicle with a continuously curved and at least partially transparent roof between a B-pillar and a storage compartment located behind it in the direction of travel, for example, a trunk, by means of which the entire curved and transparent roof can be darkened and thus the greatest possible darkening or shading effect can be achieved. The shading device comprises a shading element guided laterally along a roof contour in a rail system and supported by transverse bows, as well as a receiving box in which the shading element together with the bows can be wound up when not in use.The vehicle according to the invention has the significant advantage that the entire roof can be darkened by means of the shading device according to the invention, thereby preventing unwanted light penetration through the transparent roof. If no shading is desired, the shading element, including the frame, can be wound up in the storage box and thus stored in an aesthetically pleasing and space-saving manner. In its operating position, the shading element of the shading device can be extended at least to near the B-pillars, thus enabling extensive darkening of the roof, which is at least partially transparent and extends between the B-pillar and the trunk located behind it in the direction of travel.

[0012] In an advantageous embodiment of the motor vehicle according to the invention, the shading element comprises a fabric or plastic panel connected to the frame. Fabric panels, as well as plastic panels, can be used in virtually unlimited embodiments, with the use of natural materials, for example, adding a sustainable and ecological dimension. Plastic panels, in particular, enable extremely effective shading or blackout, especially if they are not or almost not transparent.

[0013] In an alternative embodiment of the motor vehicle according to the invention, the shading element has louvers, wherein the bows are part of or form the louvers. Such a shading element is designed in the manner of a roller shutter, thereby enabling particularly opaque darkening of the at least partially transparent roof, preferably across the entire area.

[0014] In a further advantageous embodiment of the motor vehicle according to the invention, the bows are made of spring steel. Such spring steel enables self-tensioning of the shading element, particularly if the shading element is connected to the respective bows in a tensioned manner. Alternatively, struts or tension rods can of course be used instead of such bows. Angle profiles or hollow profiles are also conceivable, as these, due to their higher bending moment, enable particularly reliable stiffening of the shading element.

[0015] In a preferred embodiment of the motor vehicle according to the invention, the rail system comprises two rails curved along the roof contour. The individual ribs are guided in these rails at their respective longitudinal ends, in particular in a noise-decoupled manner, thus enabling not only smooth but also quiet opening and closing of the sunshade. The two rails of the rail system can be recessed laterally along the roof contour into an interior lining of the headliner and / or a lateral curve of the headliner or roof longitudinal frame.

[0016] In a further advantageous embodiment of the motor vehicle according to the invention, the roof bows are either straight or curved. Straight bows offer the advantage of extremely compact roll-up capability, while curved bows, particularly if they have the same curve / shape as the curved and at least partially transparent roof, can be guided very close to the transparent roof or skylight, thereby increasing headroom and thus comfort. Straight roll-up bows that are only elastically bent under pre-tension (by pre-tensioning between the rails) can also be used accordingly.

[0017] In a particularly preferred embodiment of the motor vehicle according to the invention, the motor vehicle is designed as an off-road coupe. Especially in such off-road coupes, a comfortable rear seat for passengers is located under the transparent roof, which is why the shading device provided according to the invention also serves here as direct sun protection for the passengers sitting in the rear seats.

[0018] The roof, which is at least partially transparent, features a darkened area and a clear viewing area behind it in the direction of travel. The shading device can easily darken both the clear and darkened areas. The transparency of the darkened area can be significantly reduced or made completely opaque.

[0019] In a further advantageous embodiment of the motor vehicle according to the invention, a side window and / or a triangular window in a side door is tinted. The tinting device, along with the tinted side windows or triangular windows, provides a particularly high level of privacy for passengers sitting in the rear. Such a tinted side window also makes it difficult or impossible to unintentionally see into the vehicle, thus ensuring that items placed on the rear seat can be transported discreetly.

[0020] The shading element is designed to function as an acoustic decoupling element. This reduces acoustic reflections from the roof, which is at least partially transparent, thus significantly improving the sound experience in the rear of the vehicle. This can generally be achieved, for example, by using relatively heavy knitted, woven, or nonwoven fabrics with a high basis weight.

[0021] Further important features and advantages of the invention will become apparent from the dependent claims, the drawings and the associated description of the figures based on the drawings.

[0022] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the invention as defined by the claims. Components of a higher-level unit, such as a device, apparatus, or arrangement, mentioned above and those to be mentioned below, which are designated separately, can form separate parts or components of this unit or be integral areas or sections of this unit, even if this is depicted differently in the drawing.

[0023] Preferred embodiments of the invention are shown in the drawing and are explained in more detail in the following description, wherein identical reference numerals refer to identical or similar or functionally identical components.

[0024] Each schematically illustrates Fig. 1 an interior view of a motor vehicle according to the invention in the area of ​​the rear seats, Fig. 2 a sectional view through the motor vehicle according to the invention.

[0025] According to the Fig. 1 and Fig. Figure 2 shows a motor vehicle 1 according to the invention, which is designed, for example, as an off-road coupe, with a continuously curved and at least partially transparent roof 2 between a B-pillar 3 and a storage compartment 5 located behind it in the direction of travel 4. The roof 2 can be largely glazed and have a darkened area 6 and a clear viewing area 7 (see also Figure 2). Fig. 2) exhibit. The roof 2 is curved in the area of ​​the darkened area 6 and the clear area 7, for example as a so-called helicopter window. The darkened area 6 and the clear area 7 can be formed in one piece or in multiple pieces. The darkening of the darkened area 6 can be achieved with tinted glass or a film.

[0026] To provide eight people seated in the rear with both a sense of freedom and a so-called cocoon effect, a shading device 9 is provided to darken the at least partially transparent roof 2. This shading element 12 is guided laterally along a roof contour 10 in a rail system and supported by transverse bows 11. When not in use, this shading element 12, along with the bows 11, can be stored in a mounting box 13 (see figure). Fig. 2) can be stored in a space-saving manner. The storage box 13 is located in the direction of travel 4 behind the rear seat 8.

[0027] The shading device 9 according to the invention is designed such that it can shade or darken both the clear viewing area 7 and, if desired, the darkened area 6 of the transparent roof 2, thereby protecting a person sitting in the rear seat 8 from direct sunlight. Because the shading element 12 can be extended to the B-pillar 3, or at least to a near-proximity to the B-pillar 3, a convertible-like feeling can be created when the shading device 9 is open, even though the roof 2 is closed. With the shading element 12 extended, a protected seating position on the rear seat 8, similar to a cocoon effect, is enabled. To further enhance this cocoon effect, a side window 14 and / or a triangular window 15 can also be darkened. This can be achieved, for example, by means of appropriately tinted side windows 14a or 15.tinted triangular windows 15a and / or films.

[0028] The shading element 12 can have a fabric or plastic panel 16 connected to the mirrors 11, which is extremely flexible and can therefore be easily rolled up. Alternatively, it is of course also conceivable that the shading element 12 has slats, in which case the bows 11 are part of or form these slats. This can create a roller shutter effect.

[0029] The bows 11 can also be made of spring steel or, alternatively, as tension rods, thus enabling the shading element 12 to be tensioned automatically. As is particularly evident in the Fig.As can be seen from Figure 2, the shading device 9, or rather its shading element 12, has a longitudinally curved profile in its operating state. A transverse curvature of the shading element 12 can also be achieved by means of curved bows 9. The curved shape of the bows 11 allows the shading element 12 to be guided directly along the roof 2, i.e., with a distance of only a few millimeters to the roof 2, which is at least partially transparent. This ensures that the headroom of the persons sitting in the rear seat 8 is not, or only minimally, restricted. Alternatively, the bows 11 can also be straight, which allows for a particularly compact arrangement in the mounting box 13.

[0030] The motor vehicle 1 is preferably designed as an off-road coupe and accordingly offers space for four people, i.e., at least two people in the rear seat 8, which can be designed as a rear bench seat. Especially with such a body shape, where the roofline slopes down towards the rear in a coupé-like manner, curved bows 11 are suitable for increasing headroom. The shading device 9 provided according to the invention prevents unintentional light from entering through the transparent roof 2, in particular the clear viewing area 7, so that, for example, even people sitting in the rear seat 8 experience no problems viewing a vehicle display 17 or a laptop lying on their lap.

[0031] All in all, with the inventive motor vehicle 1, an open-air driving feeling can be achieved with the at least partially transparent roof 2 when the shading device 9 is open, while with a closed shading device 9, glare-free work on a rear seat 8 and absolute privacy can be achieved.
