Alternatively, it is conceivable that the visual and / or light protection unit completely forms the partition wall, in particular except for fastening elements. Preferably, light and / or privacy units with a thickness of at most 1 mm have a frame unit integrally formed with the privacy and / or light protection unit, while in particular visual and / or light protection units with larger thicknesses are preferably free of any integral with the vision unit. and / or light protection unit formed frame unit are formed.

In addition, it is proposed that the vehicle device has at least one aircraft side window, which is provided at least to allow a view from an interior of an aircraft to the outside, and / or a shutter and / or a panel of the aircraft side window, in which the Visual and / or light protection unit is at least partially integrated.

As a result, it is advantageously possible to adapt a light incidence from the outside according to a flight situation (take-off / cruise / landing), a time of day (day / night) and / or a wish of a passenger.

If the visual and / or light protection unit forms an inner pane of the aircraft side window at least to a large extent, advantageously a particularly effective visual and / or light protection can be made possible. In particular, advantageously a particularly effective darkening can be achieved. In particular, the aircraft side window, in which the visual and / or light protection unit is integrated, forms the inner pane of the aircraft side window, which, in particular, faces an aircraft cabin interior. By the fact that the visual and / or light protection unit "forms the inner pane of the aircraft side window to a large extent" should be understood in particular that the visual and / or light protection unit at least 80%, preferably at least 90% and preferably at least 95% of an entire Window surface of the inner pane is formed. Particularly preferably, the visual and / or light protection unit completely forms the inner pane of the aircraft side window.

In addition, it is proposed that the visual and / or light protection unit have at least two, in particular at least four, preferably at least six, preferably at least eight, and more preferably at least ten, independently electrically switchable subregions. As a result, a partial darkening of the total viewing area of the visual and / or light protection unit can advantageously be made possible. In addition, a flexibility of the visual and / or light protection unit can advantageously be achieved. In particular, the subregions each have at least one transparent state and one opaque state. In particular, the subregions are integrated in a common laminate. In particular, each sub-area is contacted separately electrically. In particular, at least one subarea, preferably each subarea, is assigned at least one separately activatable touch sensor. In particular, at least one subarea, preferably each subarea, is separately dimmable. In particular, at least one subregion, preferably each subregion, can be illuminated separately by means of an electroluminescent film.

It is also proposed that the mutually independently electrically switchable subregions of the visual and / or light protection unit are arranged side by side in a mounted state of the vehicle device in a horizontal direction. As a result, a louver-like impression of the visual and / or light protection unit can advantageously be imparted, whereby a simple and / or intuitive operation can advantageously be made possible. In addition, advantageously, a part of the privacy and / or light protection unit can be darkened, while a further part continues to allow a view through the visual and / or light protection unit. For example, this could advantageously only darken an area of a window in which a dazzling object, for example the sun, can be seen. In particular, the subregions are controllable by swiping gestures. For example, in the vertical arrangement of the subregions by means of a wiping movement over the viewing and / or light protection unit from left to right or from right to left, the opaque state or the transparent state of adjacent subregions can be set successively. Alternatively or additionally, the subregions of the sight and / or light protection unit, which can be electrically switched independently of one another, can be superimposed and / or in a vertical direction in the mounted state of the vehicle device be arranged fan-shaped side by side. A "mounted state" is to be understood, in particular, as a ready-to-operate state which is permanently installed in the vehicle, in particular the aircraft.

Furthermore, a vehicle, in particular an aircraft, with at least the vehicle device is proposed.

In addition, a method for operating a vehicle device, in particular an aircraft device, is proposed, in which at least sections of at least one visual and / or light protection unit between a transparent state, in which in particular a view through the visual and / or light protection unit is possible, and an opaque state, in which in particular a view through the viewing and / or light protection unit is at least partially blocked, preferably to a large extent, is switched electrically, wherein at a shutdown of the visual and / or light protection unit, in particular at least an active layer of the visual and / or light protection unit, applied electrical voltage from the visual and / or light protection unit, in particular at least the active layer of the visual and / or light protection unit, the transparent state is taken and / or maintained. As a result, in particular advantageous properties with regard to a transparency modification of the visual and / or light protection unit, in particular in an emergency situation, can be achieved. Advantageously, a transparent state of the visual and / or light protection unit can be made independent of an electrical voltage and / or independently of electrical work. Advantageously, a transparent state of the visual and / or light protection unit can be made independent of a functional capability of the power supply.

In addition, it is proposed that, in the event of a failure and / or a drop in electrical voltage applied to the visual and / or light protection unit, in particular to an active layer of the visual and / or light protection unit, in particular in an emergency situation, and / or light protection unit automatically the transparent state is taken and / or maintained. This can advantageously be ensured that in case of failure of the power supply a good view, especially both within a vehicle and from a vehicle interior to the outside, is possible. As a result, a high degree of safety of the vehicle device can advantageously be achieved.

The vehicle device according to the invention, the vehicle according to the invention and the method according to the invention should not be limited to the application and embodiment described above. In particular, the vehicle device according to the invention, the vehicle according to the invention and the method according to the invention for performing a function described herein can have a number deviating from a number of individual elements, components, units and method steps mentioned herein.
