Definitions

  • the invention relates to a vehicle window, in particular for a motor vehicle, the type specified in the preamble of patent claim 1 and a motor vehicle with at least one such vehicle window.
  • the vehicle window which in the present case is designed as a composite pane for roof glazing of a motor vehicle, comprises an outer layer 10 and an inner layer 12, between which at least sections a functional layer 14 is arranged, by means of which a light transmission characteristic of the vehicle window is to be influenced.
  • the light transmittance and thus the degree of darkening of the vehicle window are influenced by absorbing or reflecting part of a spectrum of a light entering in accordance with the arrows Ia and transmitting the remaining part according to the arrows Ib into an interior of the motor vehicle .
  • the functional layer 14 is additionally switchable and coupled to an electrical energy source (not shown) to provide a somewhat adjustable light transmission characteristic.
  • the vehicle window shown produces, for example, from sunlight falling in accordance with the arrows Ia a darkened or, in the case of a switchable functional layer 14, darkenable light with a dark blue hue.
  • vehicle windows with functional layers 14 are known, which can be switched between a "clear”, translucent and a “matte” state, in which they produce a diffused white light without significant darkening.
  • the functional layer 14 is usually formed as a film or applied to the outer layer 10 and the inner layer 12 by means of a coating process.
  • a disadvantage of the known vehicle windows is the fact that even with vehicle windows with switchable trained functional layers 14, only the opacity or the transmittance can be influenced, the color and thus the transmitted part of the spectrum of the incident light, however, is predetermined.
  • Object of the present invention is therefore to provide a vehicle window of the type mentioned and a motor vehicle with such a vehicle window, in which a more variable light transmission characteristic is enabled.
  • a vehicle window which allows a more variable light transmission characteristic is inventively provided in that at least one further functional layer is provided, by means of which the light transmission characteristic of the vehicle window is additionally influenced.
  • the vehicle window comprises at least two functional layers, whereby, in contrast to the prior art, an improved influencing of the degree of darkening or light transmission on the one hand and the coloring of the transmitted light on the other hand is made possible.
  • This allows a much more flexible design of the vehicle window and improved adaptability to different purposes.
  • the functional layers By interaction of the functional layers, specific wavelength ranges can be absorbed or reflected selectively from the spectrum of the incident light, as a result of which a light transmission characteristic with any desired coloration can be represented. Due to the improved influenceability of the coloration, a correspondingly improved customizability of the vehicle window as well as of a motor vehicle provided with the vehicle window is made possible. This allows an improved consideration of customer requirements and thus ensures increased customer satisfaction.
  • the at least one functional layer is switchable and has an adjustable light transmission characteristic. This allows an additional increased variability of
  • a functional layer permanently colored.
  • Switchable glazings often have an undesirable color characteristic that can be changed or at least mitigated by another, colored functional layer.
  • the functional layer may also be formed as a colored film. With the colored functional layers also customer requests can be operated individually.

  • the outer and / or the inner layer are colored in a color adapted to the light transmission characteristic of the further functional layer.
  • two or more functional layers may be interposed between the outer layer and the inner layer to achieve a desired light transmission characteristic.
  • At least two functional layers are arranged between the outer layer and the inner layer and form a multi-functional layer arrangement.
  • the functional layers are reliably protected against mechanical damage, oxidation and the like.
  • this compact arrangement of the functional layers reduces optical scattering and absorption losses, as a result of which a particularly precise selection of the wavelength ranges of the incident light to be transmitted is made possible.
  • a preferably scratch-resistant and / or adhesive intermediate layer is arranged between the outer layer and one of the functional layers and / o ⁇ er between ⁇ Je ⁇ Inner layer and one of the functional layers and / or between at least two functional layers .
  • a preferably scratch-resistant and / or adhesive intermediate layer is arranged between the outer layer and one of the functional layers and / o ⁇ er between ⁇ Je ⁇ Inner layer and one of the functional layers and / or between at least two functional layers.
  • An adhesive intermediate layer allows bonding - for example by Laminating - the relevant functional layer, whereby a reliable cohesion of the layer composite is given and the vehicle window has a high stability
  • the outer layer and / or the inner layer at least partially made of a glass, in particular a mineral glass, and / or made of a plastic / consists.
  • the vehicle window can thereby be optimally adapted to their respective intended use and used, for example, as a window, safety, sound insulation, fire or fürt ⁇ ttshemmende disc
  • this is designed as a windshield and / or as a side window and / or as a rear window and / or roof glazing and / or as a roof part of a top, in particular a folding top, for a motor vehicle
  • This allows a particularly flexible use of the vehicle window, wherein the respectively desired Licht miclasstechnikscharakte ⁇ stik is particularly easy to adapt to the particular application.

  • the invention relates to a motor vehicle with at least one vehicle window according to one or more of the preceding exemplary embodiments.
  • the more variable Licht manlasstechnikscharakte ⁇ stik and the other advantages of the vehicle window listed above it is thus possible in contrast to the prior art, to make the motor vehicle more individual and better to respond to customer requests in terms of coloration Furthermore, functionalities such as glare, visual and thermal protection be easily integrated, without having to go into the Licht miclasstechnikscharaktenstik concessions.
  • the functional layers are formed such that in addition to the transmission and absorption characteristics and the reflection characteristic of the vehicle window can be influenced.
  • the external appearance of the motor vehicle provided with the vehicle window can be made particularly variable and individual.
  • a control unit with the at least one functional layer, a permanent minimum voltage can be applied, since many switchable glazing in the dead state have a strong discoloration, whereas they are when acted upon with a very low voltage have a lower color and thus a more color-neutral appearance.
  • this low minimum voltage can be permanently applied to the switchable glazing.
