Abstract

A ceiling assembly for a vehicle includes a plurality of supporting elements for fastening components, and a plurality of connecting elements connecting the supporting elements. The plurality of connecting elements is integrally designed with the plurality of the supporting elements forming an integrated ceiling assembly. Further, a vehicle and a method for manufacturing a ceiling assembly to a ceiling of a vehicle are disclosed.

First claim

What is claimed is:

1. A ceiling assembly for a vehicle comprising:
a one-piece extruded component mountable to a ceiling of a vehicle, wherein in a cross-section through the one-piece extruded component, the one-piece extruded component includes:
a vertical wall;
at least one flange extending laterally from the vertical wall, which at least one flange is configured to mount to the ceiling of the vehicle;
at least one cable duct and at least two C-rails that extend vertically below the at least one flange; and
a housing configured to receive a lighting installation therein,
wherein in the cross-section:
the at least one cable duct includes an opening that faces upwardly; and
the at least two C-rails include respective openings facing outwardly of the one-piece extruded component;

a translucent cover mountable across an opening to the housing; and
at least one interior paneling configured to mount to at least one of the C-rails in an arrangement in which the at least one interior paneling extends downwardly from the one-piece extruded component along a body shell of an interior room of the vehicle.

2. The ceiling assembly of claim 1 , wherein when mounted to the ceiling of the vehicle, the at least one flange is configured to form an upper surface of an air duct of the vehicle.

3. The ceiling assembly of claim 2 , wherein the at least one flange is configured to carry a roof insulation when mounted to the ceiling of the vehicle.

4. The ceiling assembly of claim 1 , wherein in the cross-section, the one-piece extruded component includes at least four C-rails.

5. The ceiling assembly of claim 2 , wherein in the cross-section, the one-piece extruded component includes the air duct with air outlets when mounted to the ceiling of the vehicle.

6. The ceiling assembly of claim 1 , wherein the one-piece extruded component is an aluminum extrusion.

7. The ceiling assembly of claim 1 , wherein the one-piece extruded component is a plastic extrusion.

8. A vehicle comprising:
a body shell including an interior room and a ceiling;
a ceiling assembly comprising:
a one-piece extruded component, wherein in a cross-section through the one-piece extruded component, the one-piece extruded component includes:
a vertical wall;
at least one flange extending laterally from the vertical wall, which at least one flange is mounted to the ceiling of the vehicle;
at least one cable duct and at least two C-rails, that extend vertically below the at least one flange; and
a housing configured to receive a lighting installation therein,
wherein in the cross-section:
the at least one cable duct includes an opening that faces upwardly towards the ceiling; and
the at least two C-rails include respective openings facing outwardly of the one-piece extruded component;

a translucent cover mounted across an opening to the housing; and

at least one interior paneling mounted to at least one of the C-rails, which interior paneling extends downwardly along the body shell of the interior room of the vehicle.

9. The vehicle of claim 8 , wherein in the cross-section, the one-piece extruded component includes at least four C-rails.

10. The vehicle of claim 8 , wherein the one of the one-piece extruded component corresponds to a first one of the one-piece extruded component, wherein the ceiling assembly comprises a second one of the one-piece extruded component, wherein the first and second one-piece extruded components are arranged along the ceiling of the vehicle in a longitudinal direction of the vehicle.

11. The vehicle of claim 10 , wherein the first and second one-piece extruded components are arranged parallel to each other and form at least one air duct that extends therebetween along the ceiling of the vehicle.

12. The vehicle of claim 11 , further comprising an interior paneling connected to and extending between each of the first and second one-piece extruded components.

13. The vehicle of claim 12 , wherein the vehicle is a railway vehicle.
