Partition wall in an aircraft

1. A partition wall separating first and second longitudinally adjacent regions in an aircraft, the partition wall comprising:

a support element extending across a longitudinal direction of the aircraft;

a tension-mounted material;

a cross-strut for stiffening the support element; and

a plurality of connecting elements spaced from each other and tension-mounting the tension-mounted material to the support element at least on a first side and on a second side of the support element;

wherein the support element comprises a plurality of individually formed system components of a modular system;

wherein the tension-mounted material is supported by the support element substantially surrounding the tension-mounted material such that the partition wall is created in the aircraft; and

wherein the partition wall is mounted to a substructure of the aircraft and affixed only in the longitudinal direction of the aircraft, thereby preventing forces acting across the longitudinal direction from being transmitted to the partition wall from the substructure or from the partition wall to the substructure.

2. The partition wall of claim 1 , wherein the support element comprises a framework.

3. The partition wall of claim 2 , further comprising an illumination device in the framework.

4. The partition wall of claim 3 , further comprising a cable extending to the illumination device within at least one of the spars.

5. The partition wall of claim 2 , wherein the tension-mounted material is configured to be tension-mounted on both sides of the framework.

6. The partition wall of claim 2 , wherein the framework comprises at least one quick-acting closure device.

7. The partition wall of claim 1 , wherein the plurality of system components comprise a plurality of spars; and wherein the spars are pluggable.

8. The partition wall of claim 7 , wherein the spars are affixable among themselves by means of a tensioning mechanism.

9. The partition wall of claim 8 , wherein the tensioning mechanism comprises a quick-acting closure device.

10. The partition wall of claim 7 , wherein one of the spars comprises a joint.

11. The partition wall of claim 7 , wherein one of the spars is configured to be telescopic.

12. The partition wall of claim 7 , wherein one of the spars comprises a light and stable material.

13. The partition wall of claim 1 , further comprising an illumination device attached to the at least one cross-strut.

14. The partition wall of claim 1 , wherein the partition wall comprises an emergency exit illumination.

15. The partition wall of claim 1 , wherein the support element comprises a frame; and

wherein an affixation device rigidly connected to a substructure of the aircraft projects into the frame of the support element and affixes the partition wall only in longitudinal direction of the aircraft.

16. The partition wall of claim 15 , wherein the frame comprises a first and a second longitudinal spar and a first and a second cross-spar;

wherein the first and the second cross-spar each comprises a slot extending along their direction of longitudinal extension; and

wherein the affixation device feeds through the slots.

17. The partition wall of claim 1 , wherein the support element comprises a frame, and wherein the frame is rigidly connected to one of the at least one cross-struts.

18. The partition wall of claim 1 , wherein the plurality of connecting elements is selected from the group consisting of a loop, a strap, a rubber strap, a press-and snap fastener, a rubber cord, and a hook.
