Abstract

A rail system for fixing fittings in a cabin of a vehicle includes a first elongate rail body with a fixing side for fixing to a vehicle structure, an opposite support side with a support surface for receiving fittings, and a rail cross-section extending between the fixing side and the support side, and several fixing inserts which can be fixed along the support surface. The rail cross-section has two mutually opposing legs which are spaced apart from each other and run perpendicularly to the support surface, and the fixing inserts are configured so as not to protrude beyond the support surface.

First claim

The invention claimed is:

1. A rail system for fixing fittings in a cabin of a vehicle, comprising:
a first elongate rail body with a fixing side for fixing to a vehicle structure, an opposite support side with a support surface for receiving the fittings, and a rail cross-section extending between the fixing side and the support side;
a plurality of fixing inserts configured to be fixed along the support surface; and
at least one bridge element configured to be connected to the two mutually opposing legs on the fixing side of the rail body,
wherein the rail cross-section has the two mutually opposing legs spaced apart from each other and each running perpendicularly to the support surface, and
wherein the plurality of fixing inserts is configured so as not to protrude beyond the support surface.

2. The rail system according to claim 1 , wherein the two mutually opposing legs each have a flange pointing laterally outwards, and wherein the flange has a fixing surface parallel to the support surface on a side facing away from the support surface.

3. The rail system according to claim 1 , wherein the rail cross-section is rounded a region of the support side between the two mutually opposing legs.

4. The rail system according to claim 1 , wherein the rail cross-section has a curved transitional portion of constant form, extending completely between the two mutually opposing legs.

5. The rail system according to claim 1 , the plurality of fixing inserts comprises at least one first fixing insert,
wherein the rail body has at least one first passage bore extending from the support surface in a direction of the fixing side,
wherein the at least one first fixing insert has a retaining body with a stop face adapted to the rail cross-section and a bush extending from the stop face and having an internal thread and an outer diameter adapted to the first passage bore, and
wherein the at least one first fixing insert is configured to be pushed through the passage bore from a side of the rail body facing away from the support surface, so that the stop face lies flush on a region of the rail cross-section.

6. The rail system according to claim 1 , wherein the plurality of the fixing inserts comprises at least one second fixing insert,
wherein the at least one second fixing insert comprises a bush with an internal thread, and
wherein the at least one second fixing insert is configured to be screwed on, in or to the rail body.

7. The rail system according to claim 1 , further comprising at least one elongate rail attachment configured to be placed on the support surface of the rail body and connected to the rail body via at least one of the plurality of fixing inserts, and is configured to retain the fittings at different positions along the rail attachment.

8. The rail system according to claim 7 , wherein the at least one rail attachment has at least one seat rail attachment having a cavity enclosed between two side faces running parallel to each other and an outer face running transversely thereto, wherein the outer face has a continuous slot punctuated by mutually spaced bores having a diameter exceeding a clear width of the slot.

9. The rail system according to claim 1 , wherein the at least one bridge element comprises a plurality of bridge elements arranged in a main extension direction of the rail body, spaced apart from each other and running transversely to the two mutually opposing legs.

10. The rail system according to claim 9 , wherein the at least one bridge element has two flanges running parallel to each other and are spaced apart from each other, and configured to be connected to the two mutually opposing legs, respectively.

11. The rail system according to claim 1 , wherein the at least one bridge element is formed to be elongate and has a width corresponding to the spacing of the two mutually opposing legs on the fixing side.

12. The rail system according to claim 1 , further comprising at least one bridge element configured to be connected to the two mutually opposing legs on the fixing side of the rail body.

13. An aircraft having a floor structure and a cabin formed thereon, and at least one rail system according to claim 1 formed on or attached to the floor structure.

14. A rail system for fixing fittings in a cabin of a vehicle, comprising:
a first elongate rail body with a fixing side for fixing to a vehicle structure, an opposite support side with a support surface for receiving fittings, and a rail cross-section extending between the fixing side and the support side;
a plurality of fixing inserts configured to be fixed along the support surface; and
at least one elongate rail attachment configured to be placed on the support surface of the rail body and connected to the rail body via at least one of the plurality of fixing inserts, and is configured to retain the fittings at different positions along the rail attachment,
wherein the rail cross-section has two mutually opposing legs spaced apart from each other and each running perpendicularly to the support surface,
wherein the plurality of fixing inserts is configured so as not to protrude beyond the support surface, and
wherein the at least one rail attachment has at least one slide rail attachment having an undercut running in a main extension direction of the slide rail attachment for sliding guidance.

15. The rail system according to claim 14 , wherein the at least one slide rail attachment has at least one fixing means for fixing fittings to the slide rail attachment.

16. The rail system according to claim 14 , wherein the two mutually opposing legs each have a flange pointing laterally outwards, and wherein the flange has a fixing surface parallel to the support surface on a side facing away from the support surface.

17. The rail system according to claim 14 , wherein the rail cross-section is rounded in the region of the support side between the two mutually opposing legs.

18. The rail system according to claim 14 , wherein the rail cross-section has a curved transitional portion of constant form, extending completely between the two mutually opposing legs.

19. The rail system according to claim 14 , wherein the plurality of fixing inserts comprises at least one first fixing insert,
wherein the rail body has at least one first passage bore extending from the support surface in the direction of the fixing side,
wherein the at least one first fixing insert has a retaining body with a stop face adapted to the rail cross-section and a bush extending from the stop face and having an internal thread and an outer diameter adapted to the first passage bore, and
wherein the at least one first fixing insert is configured to be pushed through the passage bore from a side of the rail body facing away from the support surface, so that the stop face lies flush on a region of the rail cross-section.

20. The rail system according to claim 14 , wherein the plurality of the fixing inserts comprises at least one second fixing insert,
wherein the at least one second fixing insert comprises a bush with an internal thread, and
wherein the at least one second fixing insert is configured to be screwed on, in or to the rail body.
