Abstract

The invention pertains to the projection of image contents in an aircraft. A mechanical projection surface is provided that features a gear with two thrust sleeves and two gear rods. The two thrust sleeves are displaced opposite to one another due to the rotation of a threaded rod. Each of the two thrust sleeves carries along an assigned gear rod such that a projection screen is respectively retracted or extended.

Claims

1. A mechanical projection surface for a projection system for an aircraft, with said projection surface comprising:

a mechanical gear; and

a projection screen;

wherein the gear comprises a first thrust sleeve, a second thrust sleeve, a first gear rod and a second gear rod, by means of which a projection screen can be transferred from a retracted state into an extended state; and

wherein the first gear rod is connected to the first thrust sleeve and the second gear rod is connected to the second thrust sleeve; and

wherein the first and second gear rods comprise a common crossing region at which region both gear rods cross each other, wherein a position of the crossing region moves with respect to both gear rods when at least the first thrust sleeve moves.

2. The projection surface of claim 1,

wherein the gear further comprises a threaded rod that is designed for displacing the first and second thrust sleeves in opposite directions.

3. The projection surface of claim 2, further comprising:

an electric motor for driving the threaded rod.

4. The projection surface of claim 1, further comprising:

a sleeve for guiding the first and the second gear rods in an intersecting fashion when the first thrust sleeve and the second thrust sleeve are moved.

5. The projection surface of claim 1, further comprising:

a rolling device for accommodating the projection screen.

6. The projection surface of claim 5,

wherein the rolling device comprises a spring device;

wherein the spring device is designed for facilitating the process of rolling up the projection screen on a roll.

7. A projection system for an aircraft, with said projection system comprising:

a mechanical projection surface; and

a projector;

wherein the projection surface comprises a mechanical gear and a projection screen;

wherein the gear includes a first thrust sleeve, a second thrust sleeve, a first gear rod and a second gear rod, by means of which a projection screen can be transferred from a retracted state into an extended state;

wherein the first gear rod is connected to the first thrust sleeve and the second gear rod is connected to the second thrust sleeve;

wherein the projector is designed for projecting optical information onto the projection surface;

wherein the first and second gear rods comprise a common crossing region at which region both gear rods cross each other, wherein a position of the crossing region moves with respect to both gear rods when at least the first thrust sleeve moves.

8. The projection system of claim 7, wherein the gear further comprises a threaded rod that is designed for displacing the first and second thrust sleeves in opposite directions.

9. An aircraft comprising:

an interior furnishing; and

a projection system with a mechanical projection surface and a projector;

wherein the projection surface includes a mechanical gear and a projection screen;

wherein the gear includes a first thrust sleeve, a second thrust sleeve, a first gear rod and a second gear rod, by means of which a projection screen can be transferred from a retracted state into an extended state;

wherein the first gear rod is connected to the first thrust sleeve and the second gear rod is connected to the second thrust sleeve;

wherein the projector is designed for projecting optical information onto the projection surface;

wherein the projection surface and the projector are arranged on the interior furnishing; and

wherein the first and second gear rods comprise a common crossing region at which region both gear rods cross each other, wherein a position of the crossing region moves with respect to both gear rods when at least the first thrust sleeve moves.

10. The aircraft of claim 9, wherein the gear further comprises a threaded rod that is designed for displacing the first and second thrust sleeves in opposite directions.

11. The aircraft of claim 9, wherein the projection surface is completely integrated into the interior furnishing in the retracted state;

and wherein the projector is completely integrated into the interior furnishing.

12. The aircraft of claim 9, wherein the interior furnishing includes a cover panel for a Passenger Service Unit (PSU).

13. A method for extending a mechanical projection surface of a projection system in an aircraft, with said method comprising:

rotating a first threaded rod in a first direction by means of an electric motor;

displacing first and second thrust sleeves in opposite directions due to the rotation of the first threaded rod; and

guiding the first threaded rod and a second threaded rod in an intersecting fashion when the first thrust sleeve and the second thrust sleeve are displaced in opposite directions;

wherein first and second gear rods comprise a common crossing region at which region both gear rods cross each other, wherein a position of the crossing region moves with respect to both gear rods when at least the first thrust sleeve moves.

14. A method for retracting a mechanical projection surface of a projection system in an aircraft, with said method comprising:

rotating a first threaded rod in a second direction by means of an electric motor;

displacing first and second thrust sleeves in opposite directions due to the rotation of the first threaded rod; and

guiding the first threaded rod and a second threaded rod in an intersecting fashion when the first thrust sleeve and the second thrust sleeve are displaced in opposite directions;

wherein first and second gear rods comprise a common crossing region at which region both gear rods cross each other, wherein a position of the crossing region moves with respect to both gear rods when at least the first thrust sleeve moves.
