Abstract

A fastening system for passenger seats in a vehicle cabin has two or more guide rails to be integrated into or onto a cabin floor, and a plurality of slides, to be brought into engagement with the guide rails and having a flange for connection to a passenger seat in order to retain the passenger seat on a guide rail. Each guide rail has a profile cross section, perpendicularly to a main axis of extent, having a base region and a supporting region. Each slide has a cavity of complementary design with the profile cross section. The guide rails have a plurality of transverse openings spaced apart from one another between the base region and the supporting region. At least one slide has a displaceably mounted retaining body which, when the slide is in engagement with the guide rail, can be brought into engagement with one of the transverse openings.

First claim

The invention claimed is:

1. A fastening system for passenger seats in a cabin of a vehicle, comprising:
two or more guide rails configured to be integrated into or onto a floor of the cabin, and
a plurality of slides configured to be brought into engagement with one of the two or more the guide rails and having a flange for connection to a passenger seat in order to retain the passenger seat on the one of the two or more guide rail,
wherein each of the two or more guide rails has a profile cross section, perpendicularly to a main axis of extent, having a base region and a supporting region,
wherein each of the plurality of slides has a cavity of complementary design with the profile cross section of a corresponding one of the two or more guide rails,
wherein the two or more guide rails have a plurality of transverse openings spaced apart from one another between the base region and the supporting region, each of said plurality of transverse openings having an opening in a sidewall of the two or more guide rails and extending transverse to a longitudinal axis of the two or more guide rails, and
wherein at least one slide of the plurality of slides has at least one displaceably mounted retaining body which, when the at least one slide is in engagement with a corresponding one of the two or more guide rails, is configured to be brought into engagement with one of the plurality of transverse openings.

2. The fastening system according to claim 1 , wherein the plurality of transverse openings has an elongate profile extending substantially completely through a corresponding one of the two or more guide rails.

3. The fastening system according to claim 1 ,
wherein the two or more guide rails have at least one undercut arranged between the supporting region and the base region,
wherein the cavity of each of the plurality of slides has a necked region, thus enabling the supporting region to be enclosed by the cavity, and
wherein each of the plurality of slides has at least one rotatably mounted roller projecting into the necked region and configured to be brought into surface contact with a surface of a corresponding one of two or more guide rails.

4. The fastening system according to claim 1 , wherein the plurality of transverse openings extend completely through corresponding one of the two or more guide rails.

5. The fastening system according to claim 1 ,
wherein the at least one slide of the plurality of slides has a bearing device for a displaceable bearing of the at least one displaceably mounted retaining body,
wherein the at least one displaceably mounted retaining body has an elongate end and an engagement element, wherein the engagement element points toward a corresponding one of the plurality of transverse openings, and
wherein the elongate end projects visibly from the bearing device in a non-retained position of the at least one displaceably mounted retaining body and does not project over the bearing device in a retaining position.

6. The fastening system according to claim 1 , wherein the at least one displaceably mounted retaining body is a sprung pin urged by a spring force into a retaining position.

7. The fastening system according to claim 1 ,
wherein the plurality of transverse openings have a step and a tapered outlet opening,
wherein the tapered outlet opening of at least one of the plurality of transverse openings is oriented in a laterally reversed manner to another of the plurality of transverse openings, and
wherein the at least one displaceably mounted retaining body is configured to be brought into engagement exclusively with a region of the at least one of plurality of transverse openings that faces away from the tapered outlet opening.

8. The fastening system according to claim 1 , wherein the profile cross section of the two or more guide rails has two mutually opposite undercuts.

9. The fastening system according to claim 3 , wherein the at least one slide has two mutually spaced rollers for the at least one undercut, each of the two mutually spaced rollers configured to be brought into surface contact with the surface of a corresponding one of the two or more guide rails.

10. The fastening system according to claim 9 ,
wherein the profile cross section of the two or more guide rails has two mutually opposite undercuts, and
wherein the at least one slide has at least one pair of mutually opposite rollers for engagement in two mutually opposite regions of the profile cross section of a corresponding one of the two or more guide rails.

11. The fastening system according to claim 9 , wherein all the rollers are arranged on a common plane and are mounted so as to be rotatable about a respective axis perpendicular to the common plane.

12. A passenger seat system for a cabin of a vehicle, comprising:
at least one passenger seat device having a seat frame, and
a fastening system according to claim 1 ,
wherein the fastening system has two mutually spaced guide rails running parallel to each other,
wherein the seat frame of the at least one passenger seat device has two pairs of mutually spaced seat legs, which are each connected to one slide, and
wherein the slides are in engagement with the guide rails.

13. The passenger seat system according to claim 12 , wherein the guide rails are configured to be fastened on seat rails arranged in a floor of a cabin of the vehicle.

14. A vehicle having a cabin, a floor and at least one passenger seat system according to claim 12 .

15. The vehicle according to claim 14 , wherein the vehicle is an aircraft.
