Vehicle device and method using a vehicle device

1. An aircraft device in an aircraft, comprising:

a window unit;

a partition wall in which the window unit is at least partly integrated, the partition wall comprising a frame unit and a separating unit, the separating unit comprising the window unit and being arranged in a separating unit accommodation region of the frame unit; and

a transparency switching unit that is, in a first operating state, which is a de-energized state that is a zero current or zero voltage state, configured to enable a view through the window unit,

wherein the transparency switching unit comprises an illuminating unit that is configured to at least partly prevent a view through the window unit in a second operating state,

wherein the transparency switching unit is free of movable components,

wherein the illuminating unit is arranged in a proximity of the window unit,

wherein the illuminating unit is different from a vehicle interior illumination unit,

wherein the illuminating unit is at least partly integrated in the frame unit,

wherein the frame unit is configured to absorb at least a major part of the weight of the separating unit, and

wherein the frame unit is different from a supporting structure of the aircraft, including a floor, a ceiling, a side wall, a luggage rack and/or any further structural component of the aircraft.

2. The aircraft device as claimed in claim 1 ,

wherein the illuminating unit is configured for the emission of light beams that are at least essentially parallel to a main extension plane of the window unit.

3. The aircraft device as claimed in claim 1 ,

wherein the transparency switching unit comprises an optically active structural unit for an at least partial prevention of a view through the window unit.

4. The aircraft device as claimed in claim 3 , wherein

the structural unit is configured to influence a light direction of light beams.

5. The aircraft device as claimed in claim 3 , wherein

the structural unit is configured to superimpose light beams passing through the window unit with light beams of the illuminating unit.

6. The aircraft device as claimed in claim 3 , wherein

the window unit comprises a viewing pane, with which the structural unit is embodied at least partly in a one-part implementation.

7. The aircraft device as claimed in claim 1 ,

wherein the window unit comprises a viewing pane that extends over at least 20% of a cover surface of the dividing wall.

8. The aircraft device as claimed in claim 1 ,

wherein the window unit comprises a viewing pane that extends, in a mounted state, over at least 60% of a transverse extension length of the partition wall.

9. An aircraft with a vehicle device as claimed in claim 1 .

10. An aircraft device, comprising:

a window unit comprising a viewing pane; and

a transparency switching unit that is, in a first operating state, configured to enable a view through the window unit,

wherein the transparency switching unit comprises an electrically actuable transparency unit that at least partially prevents a view through the window unit in a second operating state,

wherein the transparency unit is a film that is arranged in a proximity of the window unit,

wherein the transparency unit comprises a working connection to a control unit of the aircraft device, the control unit being configured to control the transparency of the transparency unit,

wherein when not actuated and/or not energized, the transparency unit is transparent, and

wherein in the event of electrical actuation of the transparency unit, the transparency unit is opaque.

11. An aircraft device according to claim 10 ,

wherein the transparency unit is a liquid crystal film.

12. An aircraft device according to claim 10 ,

wherein the transparency unit is arranged on a viewing area of the viewing pane.

13. An aircraft device according to claim 10 ,

wherein the transparency unit is bonded to the viewing pane.

14. An aircraft device according to claim 10 ,

wherein the transparency unit is arranged between two viewing panes of the window unit.

15. An aircraft device according to claim 10 ,

wherein the transparency unit extends substantially over the entire area of the viewing pane.

16. An aircraft device according to claim 10 ,

wherein the transparency unit is a retrofit unit.
