Abstract

A rail system, in particular for assembling or fastening seats in an aircraft, includes an assembly rail, in particular a seat rail for assembling or fastening a seat, a first panel, in particular a first floor panel for arrangement next to and substantially in parallel with the assembly rail, and at least one cover element which is movable between a first position in or on the first panel and a second position for covering the assembly rail, wherein an upper surface of the at least one cover element in the second position is located substantially in a plane with a surface of the first panel.

Claims

1. A rail system comprising:

an assembly rail;

a first panel; and

at least one cover element which is movable between a first position, in which the at least one cover element is received in a recess in the first panel or is arranged on the first panel, and a second position for covering the assembly rail,

wherein an upper surface of the at least one cover element in the first position and in the second position is located substantially in a plane with an upper surface of the first panel.

2. The rail system according to claim 1, wherein, in the second position, the upper surface of the at least one cover element merges in a planar manner substantially smoothly into the upper surface of the first panel.

3. The rail system according to claim 1, wherein the at least one cover element is pivotable between the first position and the second position, or wherein the at least one cover element can be displaced between the first and second positions.

4. The rail system according to claim 3, wherein the at least one cover element is pivotable through an angle of up to and including 180°

.

5. The rail system according to claim 1, wherein the first panel comprises a levelling device for levelling the upper surface of the first panel or for filling a recess in the first panel when the at least one cover element is in the second position.

6. The rail system according to claim 5, wherein the levelling device comprises a filler element which is movable out of a position, which is inactive, recessed, or inserted in the first panel, into a filling position when the at least one cover element is in the second position, wherein, in the filling position, an upper surface of the filler element is located substantially in the plane with the upper surface of the first panel.

7. The rail system according to claim 6, wherein the filler element is configured such that the filler element can be removed from and reintroduced into the position which is inactive, recessed, or inserted in the first panel and wherein the levelling device also comprises a sliding piece which is configured for lateral displacement so that the sliding piece is displaceable between a retracted position, next to the filler element located in the inactive, recessed, or inserted position, and an extracted position, when the filler element is moved into the filling position.

8. The rail system according to claim 1, wherein the at least one cover element is configured as a rigid or semi-rigid flap, tab, plate or sheet;

and/or

wherein the system comprises a holder mechanism by which the at least one cover element is held in at least one of the first and second positions; and

/or

wherein the at least one cover element is pretensioned into at least one of the first and second positions by a spring element.

9. The rail system according to claim 1, wherein the first panel has a plurality of cover elements which are arranged in a row one after another along and next to the assembly rail, wherein the assembly rail has a plurality of fastening points arranged at regular intervals, and wherein each of the plurality of cover elements is arranged in order to cover a respective fastening point.

10. The rail system according to claim 1, further comprising a second panel comprising a surface substantially in the plane with the upper surface of the first panel.

11. The rail system according to claim 10, wherein the second panel is a second floor panel for arrangement next to and substantially in parallel with both the assembly rail and the first panel on one side of the assembly rail opposite the first panel.

12. The rail system according to claim 1, wherein the assembly rail comprises a projection for supporting a peripheral region of the first panel and wherein the at least one cover element is attached to the peripheral region of the first panel.

13. The rail system according to claim 1, wherein the assembly rail comprises a duct for guiding a cabling system and wherein the at least one cover element also covers the duct in the second position.

14. The rail system according to claim 1, wherein the assembly rail is a seat rail for assembling or fastening a seat in an aircraft and wherein the first panel is a first floor panel for arrangement next to and substantially in parallel with the assembly rail.

15. An aircraft having a fuselage structure which comprises at least one deck which has a rail system comprising:

an assembly rail;

a first panel; and

at least one cover element which is movable between a first position, in which the at least one cover element is received in a recess of the first panel or is arranged on the first panel, and a second position for covering the assembly rail,

wherein an upper surface of the at least one cover element in the first position and in the second position is located substantially in a plane with an upper surface of the first panel.

16. A rail system comprising:

an assembly rail;

a first panel; and

at least one cover element which is movable between a first position, in which the at least one cover element is received in a recess in the first panel or is arranged on the first panel, and a second position for covering the assembly rail,

wherein an upper surface of the at least one cover element in the second position is located substantially in a plane with a surface of the first panel,

wherein the first panel comprises a levelling device for levelling the surface of the first panel or for filling a recess in the first panel when the at least one cover element is in the second position.
