Abstract

The invention discloses a filling system for an operating fluid container (1) of a motor vehicle, comprising a filling hose (10) and at least one filling hose holding device (20). The filling hose holding device (20) can be fastened in an installation space of the motor vehicle, and the filling hose (10) can be fluid-connected to an operating fluid container (1) and to a filling neck (30). The filling hose (10) can be fastened in the installation space of the motor vehicle by means of the filling hose holding device (20) in such a manner that the filling hose (10) follows a contour defined by the filling hose holding device (20).

First claim

The invention claimed is:

1. A filling system for an operating fluid container of a motor vehicle, comprising (a) a filling hose and (b) at least one filling hose holding device comprising a contoured portion, wherein
(i) the filling hose holding device is configured to be fastened in an installation space of the motor vehicle;
(ii) the entire filling hose is flexible and is configured to be fluidically connected to the operating fluid container and to a filling neck; and
(iii) the filling hose is configured to be fastened in the installation space of the motor vehicle by engagement with the at least one filling hose holding device such that a portion of the filling hose, when engaged with filling hose holding device, assumes a S-shaped contour defined by the contoured portion of the filling hose holding device.

2. The filling system of claim 1 , wherein the filling hose holding device comprises at least one undercut configured to engage the filling hose.

3. The filling system of claim 2 , wherein the undercut is of elastic design.

4. The filling system of claim 1 , wherein the filling hose holding device configured to define a contour shell.

5. The filling system of claim 1 , wherein the filling hose holding device is configured to define a contour comprising at least one bend, and wherein the filling hose when engaged with the filling hose holding device assumes the bend of the filling hose holding device.

6. The filling system of claim 1 , wherein the filling hose holding device comprises at least one predetermined break point.

7. The filling system of claim 1 , wherein the filling hose holding device comprises at least one fire barrier and/or one impact barrier.

8. The filling system of claim 1 , wherein the filling hose holding device is configured as a wheel house shell with integrated holding device for holding the filling hose.

9. The filling system of claim 1 , wherein the filling hose is a multi-layer filling hose comprising an integrated barrier layer for hydrocarbons.

10. The filling system of claim 1 , wherein the filling hose comprises a coaxial recess defining a concave cross section.

11. The filling system of claim 1 , wherein the filling hose comprises at least one corrugated portion.

12. The filling system of claim 1 , wherein the filling hose comprises at least one portion comprising a helically wound reinforcement structure disposed along the exterior the filling hose.

13. The filling system of claim 1 , wherein the filling hose is a double hose comprising an inner hose disposed within an outer hose.

14. The filling system of claim 13 , wherein the outer hose comprises corrugated hose, and the inner hose comprises smooth hose.

15. The filling system of claim 13 , wherein the outer hose comprises a reinforcement structure disposed helically on the exterior of the outer hose.

16. The filling system of claim 13 , wherein the inner hose is a multi-layer inner hose comprising an integrated barrier layer for hydrocarbons, and/or the outer hose is a multi-layer outer hose comprising an integrated barrier layer for hydrocarbons.

17. An operating fluid container comprising the filling system of claim 13 , wherein the inner hose and the outer hose of the filling hose are each fluidically connected to the operating fluid container and to the filling neck; an operating fluid can be filled into the operating fluid container via the filling neck and the inner hose; and an intermediate space between the outer hose and the inner hose of the filling hose forms a venting line between the interior of the operating fluid container and the filling neck.

18. A motor vehicle comprising the operating fluid container of claim 17 , wherein the filling hose holding device is fastened in an installation space of the motor vehicle; the filling hose is held in the installation space of the motor vehicle by the filling hose holding device; and a first end of the filling hose is fluidically connected to the operating fluid container and a second end of the filling hose is fluidically connected to the filling neck.

19. The filling system of claim 13 , wherein the inner hose is connected to the outer hose at least in certain sections via material webs in such a way that the position of the inner hose is secured in the outer hose.

20. An operating fluid container comprising a filling neck and the filling system of claim 1 , wherein a first end of the filling hose is fluidically connected to the operating fluid container and a second end of the filling hose is fluidically connected to the filling neck; and wherein the filling hose can be fastened in the installation space of the motor vehicle by engagement with at least one filling hose holding device such that the filling hose follows at least one contour defined by the at least one filling hose holding device.

21. A motor vehicle comprising the operating fluid container of claim 20 , wherein the filling hose holding device is fastened in an installation space of the motor vehicle; the filling hose is held in the installation space of the motor vehicle by the filling hose holding device; and the first end of the filling hose is fluidically connected to the operating fluid container and the second end of the filling hose is fluidically connected to the filling neck.
