Embodiment Construction

[0045] figure 1 A schematic illustration of a roof region 4 of a motor vehicle 1 according to a first embodiment of the invention is shown. In this embodiment of the invention, the roof region 4 has a sunroof 6 and a rear window 7 . To protect the vehicle occupants from the incoming heat and light, the sunroof 6 and the rear window 7 can be gradually shaded or darkened. In contrast to known sun visors and roller sun blinds which can only be closed completely or partially, this roof structure 5 with sunroof 6 and rear window 7 has an optical structure which is barely perceptible to the eyes of passengers, which enables For stepless adjustment of light transmittance. In this first embodiment, this shading possibility is based on the fact that the films with a striped structured polarization pattern are arranged one above the other.

[0046] The polarized stripes have the same width, wherein adjacent stripes have polarization directions offset by 90° from each other. Here, th...

Abstract

A vehicle is provided with transparent roof area having at least one roof window tailored to fit into the roof structure. An adjustable darkening against exposure to incident light is provided toward the passenger compartment. The roof area has a first optically structured, immovably fixed surface and a second optically structured, movable surface. The first and second surfaces are arranged one over the other. The second surface here abuts the first surface so that it can slide over it. While the first surface takes up the entire roof window, the second surface is arranged at least in partial areas of the roof window. The second surface is arranged so that it can move relative to the first surface in such a way that the optical structures lying one over the other alter the incident light as a function of position.

Description

technical field [0001] The invention relates to a motor vehicle with a transparent roof region, which has at least one sunroof inserted into the roof structure. An adjustable incident light shading device is provided towards the interior of the vehicle. Background technique [0002] Such a shading of the sunroof towards the interior is realized in the prior art by shutters which are partially or completely pushed or pulled under the sunroof. This shading protects the interior and passengers from glare, especially heat radiation and reduces the burden on the air conditioning during the hotter months of the year. Guiding and installing the shutter is time-consuming, maintenance-intensive and cost-intensive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a planar shading device that cooperates with the skylight, and the shading device can gradually adapt to the incident light and heat. [0004] This technical pr...
