[0030] FIG. 5 shows another schematic illustration of the sunshade according to the further embodiment of the present invention integrated in the roof of a vehicle 10; and

[0031] FIG. 6 shows a schematic illustration of a sunshade 20 according to another embodiment of the present invention.

[0032] By providing a sunshade according to the present invention, dazzling a person located in vehicle 10 can be prevented.

[0033] FIG. 1 shows a schematic illustration of a sunshade according to an embodiment of the present invention integrated in a roof of a vehicle 10.

[0034] The sunshade includes a slidable sunshade element 14. Slidable sunshade element 14 is configured in a panel-like and dimensionally stable manner. For example, it may be disposed in guide tracks, which are attached at an interior side of the roof. Slidable sunshade element 14 is located in the area of an opening 12 in the roof and is, as shown in FIG. 1, freely positionable in opening 12. Thus, dazzling a person, for example a driver of vehicle 10, by sunlight irradiating through opening 12 may be prevented.

[0035] Sunshade element 14 is positioned in opening 12 of the roof in vehicle 10 in such a manner that it may partially block irradiating sunlight by sliding in translucent opening 12 and the dazzling of the person in the vehicle may be prevented. For this purpose, sunshade element 14 is preferably inserted into the lateral guide tracks, within which sunshade element 14 is slidable. The positionability of sunshade element 14 ensures a dazzle protection effect independent from the angle of incidence of the sunlight through the roof and enables a blocking of irradiation of sunlight in the area of a person located in vehicle 10 without that the irradiation of sunlight or the penetration of fresh air into vehicle 10 in this incidence is completely prevented.

[0036] Preferably, the area of sunshade element 14 is between 10% and 50% of the total area of two sunshade elements 14 and 16, particularly preferably between 20% and 40% of two sunshade elements 14 and 16 and especially particularly preferably between 25% and 35%, such as 30% of the total area of two sunshade elements 14 and 16. In the preferred embodiment, the sunshade element is solidly configured, thus, configured as a solid material. For example, the sunshade element may be carried out in the form of a plastic panel. The thickness of such panels is preferably at most 7 mm or less, 5 mm or less or 3 mm or less.

[0037] Furthermore, sunshade element 14 may be modifiable in surface area, for example by additional roller blind-like elements which can be pulled out from the sunshade element and which expand the surface area of the sunshade element. Another possibility is provided by disposed auxiliary panels of a telescopic or stack type, which may be extended or retracted or pulled apart and pushed together from or under sunshade element 14 to so enlarge or diminish the surface area of the sunshade. The telescopic-type configuration is particularly suited for solidly formed, flat panels.

[0038] The sunshade may include a further sunshade element 16. Further sunshade element 16 may be configured as a type of a roller blind or in a rollable manner; however, it may also be configured in the form of a panel. As shown in FIG. 1, further sunshade element 16 is located under a translucent part of the roof and is rolled up or can there be inserted.

[0039] Further sunshade element 16, by itself or in combination with first sunshade element 14, can completely seal opening 12 against irradiating sunlight. In this instance, two sunshade elements 14 and 16 are preferably located in the same lateral guide tracks. Then, sunshade element 14 and additional sunshade element 16 together can completely cover opening 12 in the roof. The guide tracks for further sunshade element 16 can however also be provided in addition to guide tracks for sunshade elements 14, so that for example a conventional cover on the inside of the sunroof can completely seal the opening in the roof and sunshade element 14 is only used if further sunshade element 16 has at least partially been moved out of opening 12. Further sunshade element 16 is preferably disposed in a rear area of the roof and can be diminished by rolling up its light-blocking surface area or enlarged by unrolling the surface area. The modification of the area of further sunshade element 16 enables the person located in the vehicle to adapt the light conditions to a respective situation.

[0040] The sunshade according to the present invention is insertable into all roof variations of vehicle 10 and may be used in an open roof, for example a sunroof exposing the roof opening or a folding roof, as well as in a covered, translucent roof, for example a panoramic glass roof or another translucent panoramic roof. This enables to ideally adapt the irradiation of sunlight through opening 12 in the roof depending on the weather, because the sunshade is equally usable in warm outside temperatures having an open roof and in cold outside temperatures having a closed, translucent roof.

[0041] FIG. 2 shows a schematic illustration of a sunshade according to a further embodiment of the present invention integrated in a roof of a vehicle 10.

[0042] The sunshade again includes a slidable sunshade element 14. Slidable sunshade element 14 is configured in a panel-like and dimensionally stable manner. For example, it may be disposed in guide tracks, which are attached at an interior side of the roof.

[0043] The sunshade can include a further sunshade element 16 which, in particular, is also freely positionable. Further sunshade element 16 is also configured in a panel-like and dimensionally stable or in a roller blind-type manner. It also can be disposed in the guide tracks. As shown in FIG. 1, further sunshade element 16 is located under a translucent part of the roof. Further sunshade element 16 is again preferably disposed in a rear and/or front area of the roof and, by sliding under the translucent part of the roof, it may be modified in its light-blocking surface area. For this purpose, elements 14 and 16 are positionable independently from each other. The elements can be guided in the same guide tracks in the longitudinal or transverse direction.

[0044] FIG. 3 shows a further schematic illustration of the sunshade according to the embodiment of the present invention integrated in the roof of vehicle 10 in a fully opened state.

[0045] In reference to FIG. 1, slidable sunshade element 14 is now slid under the translucent part and is located next to rolled-up further sunshade element 16, so that opening 12 in the roof is completely open.

[0046] FIG. 4 shows a further schematic illustration of the sunshade according to the embodiment of the present invention integrated in the roof of vehicle 10 in a fully opened state.

[0047] In reference to FIG. 2, slidable sunshade element 14 is now slid under the translucent part and is located next to further sunshade element 16, so that opening 12 in the roof is completely exposed.

[0048] FIG. 5 shows another schematic illustration of the sunshade according to the further embodiment of the present invention integrated in the roof of vehicle 10 in a closed state.

[0049] In reference to FIGS. 2 and 4, slidable sunshade element 14 and further sunshade element 16 are slid into opening 12 and together completely seal the opening against irradiating sunlight.

[0050] FIG. 6 shows a schematic illustration of a sunshade 20 according to another embodiment of the present invention.

[0051] Sunshade 20 includes sunshade element 14 and a switch element 24 for detecting instructions from the person and/or for operating sunshade element 14 and/or light sensor 26 for the detection of irradiating sunlight. Furthermore, sunshade 20 may include a further sunshade element 16. Sunshade 20 may furthermore include a control device 22, which is connected to sunshade element 14, switch 24, light sensor 26 and/or further sunshade element 16, for controlling or regulating sunshade 20. For this purpose, control device 22 may take into account a threshold value and/or control or regulate sunshade 20 as a function of an intensity of the irradiation of sunlight.

[0052] Slidable sunshade element 14 may be manually positioned. In this instance, sunshade element 14 can be directly slidable by a manual sliding movement and/or indirectly slidable via electric controller 22 by manually operating switch element 24. This enables a person located in the vehicle to directly determine the position of the sunshade element.

[0053] Furthermore, the sunshade according to the present invention may include light sensor 26 detecting the irradiating sunlight. In so doing, sunshade element 14 may be positioned as a function of the irradiated sunlight detected by light sensor 26 and enables an automatic alignment without the influence of a person located in the vehicle.

[0054] Light sensor 26 detecting the irradiated sunlight may be disposed in vehicle 10 in such a manner that the irradiation of sunlight can be detected in the area of a person located in vehicle 10. Preferably, light sensor 26 is attached at a head rest, particularly preferably at the head rest of a driver seat. In so doing, light sensor 26 may be disposed directly in the area of the interior in which the sunlight irradiated through the opening in the roof is to be determined.

[0055] The sunshade according to the present invention, including slidable sunshade element 14 and optionally further sunshade element 16, which, for example, can be rollable or slidable, switch device 24, light sensor 16 and/or control device 22, can be integrated in vehicle 10.
