Abstract

A floor panel for a floor of a passenger cabin of a mobile platform is provided, which comprises a base body with an integrated cable channel and a cover element covering the cable channel. The base body is realized in the form of a sandwich component including two honeycomb structures, between which the cable channel is arranged. The cover element is firmly attached to the base body, thereby creating a self-supporting floor panel. Since the cover element is firmly attached to the base body, the thickness and weight of the base body may be reduced.

First claim

What is claimed is:

1. A floor panel for a floor of a passenger cabin of a mobile platform, the floor panel comprising:
a base body having a cable channel extending along a longitudinal direction of the base body for accommodating electric cables; and
a planar cover element arranged on top of the cable channel and a part of the top surface of the base body for covering the cable channel, the cover element firmly attached to the base body at positions left and right of the cable channel;
wherein the base body comprises a sandwich component that includes a first honeycomb structure and a second honeycomb structure, the first honeycomb structure extending from a left edge of the base body to a left side of the cable channel and the second honeycomb structure extending from a right edge of the base body to a right side of the cable channel, the cable channel being arranged between the first and second honeycomb structures;
wherein both the first honeycomb structure and the second honeycomb structure share a common top cover layer and a common bottom cover layer;
wherein the top cover layer and the bottom cover layer meet each other in the region of the cable channel to form the bottom of the cable channel; and
wherein the floor panel is self-supporting when being supported along its left and right edges only if the cover element is attached to the base body.

2. The floor panel of claim 1 ,
wherein the cover element is a metal sheet.

3. The floor panel of claim 1 , wherein the floor panel is arranged between a first seat rail and a second seat rail which is parallel to the first seat rail, and the base body comprises a first attachment region parallel and adjacent to the left edge of the base body for attachment to the first seat rail and a second attachment region parallel and adjacent to the right edge of the base body for attachment to the second seat rail.

4. The floor panel of claim 1 ,
wherein the top cover layer includes a first carbon fibre reinforced plastic layer comprising parallel arranged fibres having longitudinal axes in a first direction and a second carbon fibre reinforced plastic layer comprising parallel arranged fibres having longitudinal axes in a second direction, which is different from the first direction.

5. The floor panel of claim 1 ,
wherein the bottom cover layer includes a plurality of carbon fibre reinforced plastic layers.

6. The floor panel of claim 1 , further comprising:
at least one primary coil for a wireless transmission of electric signals from the primary coil to a receiver of an electric consumer.

7. The floor panel of claim 6 ,
wherein the electric consumer is an entertainment device integrated in a passenger seat.

8. The floor panel of claim 6 ,
wherein the at least one primary coil is integrated in the cable channel or in the cover element.

9. A floor panel arrangement for a passenger cabin of a mobile platform, the arrangement comprising:
a first floor panel and a second floor panel, at least one of the first floor panel and the second floor panel including a base body having a cable channel extending along a longitudinal direction of the base body for accommodating electric cables, and a planar cover element arranged on top of the cable channel and a part of top surface of the base body for covering the cable channel, the cover element attached to the base body at positions left and right of the cable channel, the base body comprising a sandwich component that includes a first honeycomb structure and a second honeycomb structure, the first honeycomb structure extending from a left edge of the base body to a left side of the cable channel and the second honeycomb structure extending from a right edge of the base body to a right side of the cable channel, the cable channel being arranged between the first and second honeycomb structures, both of the first honeycomb structure and the second honeycomb structure sharing a common top cover layer and a common bottom cover layer, wherein the top cover layer and the bottom cover layer meet each other in the region of the cable channel to form the bottom of the cable channel; and
a connecting element connecting the first floor panel to the second floor panel, the connecting element including:
a flat middle region which is positioned in the cable channel of the first floor panel and the cable channel of the second floor panel on top of and adjacent to the top cover layers of the first floor panel and the second floor panel respectively,
wherein the at least one floor panel is supported along its left and right edges when the cover element is attached to the base body.

10. The floor panel arrangement of claim 9 , the connecting element further comprising:
a left side portion and a right side portion arranged between the first floor panel and the second floor panel.

11. A mobile platform, comprising:
a cabin with at least one floor panel that includes a base body having a cable channel extending along a longitudinal direction of the base body for accommodating electric cables, and a planar cover element arranged on top of the cable channel and a part of top surface of the base body for covering the cable channel, the cover element coupled to the base body,
wherein the base body comprises a sandwich component that includes a first honeycomb structure and a second honeycomb structure, the first honeycomb structure extending from a left edge of the base body to a left side of the cable channel and the second honeycomb structure extending from a right edge of the base body to a right side of the cable channel, the cable channel being arranged between the first and second honeycomb structures, and both the first honeycomb structure and the second honeycomb structure share a common top cover layer and a common bottom cover layer, wherein the top cover layer and the bottom cover layer meet each other in the region of the cable channel to form the bottom of the cable channel, and
wherein the at least one floor panel is self-supporting when supported along its left and right edges when the cover element is attached to the base body.

12. The mobile platform of claim 11 , wherein the mobile platform is an aircraft.

13. The mobile platform of claim 11 , further comprising:
at least one primary coil for a wireless transmission of electric signals from the primary coil to a receiver of an electric consumer.

14. The mobile platform of claim 13 , wherein the electric consumer is an entertainment device integrated in a passenger seat of the mobile platform.

15. The mobile platform of claim 13 , wherein the at least one primary coil is integrated in the cable channel or in the cover element.
