11. The fuel tank recess body of claim 8, wherein the base portion further includes a tank feed line seal adapted to seal against a tank feed line.

12. The fuel tank recess body of claim 11, wherein the tank feed line seal is tubular.

13. The tank recess body of claim 8, wherein the flange is formed from a connecting part that is fastened to the inner plate.

14. The tank recess body of claim 8, wherein the flange is formed integrally with the inner plate.

15. The tank recess body of claim 8, wherein the tank recess body is located in a vehicle body opening of the motor vehicle.

16. A fuel tank recess, mountable within a motor vehicle having an outer plate and an inner plate, for providing access to a fuel tank feed line, said fuel tank recess comprising: a tank recess body including a rigid first region adapted to be fastened to the outer plate and a flexible base portion connected to the first region, the base portion having a tubular tank feed line seal, adapted to seal against the tank feed line, and a fold-over sealing edge; and a flange mounted on the inner plate for receiving the fold-over sealing edge whereby, when the tank recess body is placed between the outer and inner plates, the fold-over sealing edge is configured to fold over the flange, thereby holding the tank recess body in place.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows a schematic section of a tank recess with a flange formed from a connecting part that is fastened to the inner plate of a motor vehicle.

(2) FIG. 2 shows a schematic section of a tank recess with a flange formed integrally with the inner plate of the motor vehicle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(3) Further details, features and advantages of the invention are revealed from the following description of exemplary embodiments, with reference to FIGS. 1 and 2 in which a schematic section through a tank recess 1 is shown.

(4) The tank recess 1 comprises in section an approximately U-shaped recess body 2 which has a filler cap 3 which is able to be pivoted open and shut. The recess body 2 is fastened from the outside to the outer metal plate 4 of a vehicle body opening 11 and extends inwards along the vehicle body opening 11 to the inner metal plate 5.

(5) The recess body 2 comprises a first region 6 with a wall made of a more rigid plastics and a base portion 7 adjacent thereto made of a more flexible plastics material which is injection-molded thereon. The base portion 7 has at the lower end, i.e. in the region of the inner metal plate 5 of the vehicle body opening 11, a flexible, rubber elastic and tubular sealing edge 10.

(6) Said sealing edge is configured so as to grip sealingly around a peripheral flange 8 in the final position. In the present case, as shown in FIG. 1, the flange is formed from a separate connecting part 12 which is fastened from the inside on the vehicle body opening 11 to the inner metal plate 5 and forms a seal with the inner metal plate 5. Alternatively, flange 8 is formed from the inner metal plate 5, as shown in FIG. 2, wherein the flange 8 is formed integrally with the inner metal plate 5.

(7) Between the first region 6 and the sealing edge 10 of the recess body 2, a tubular tank feed line seal 9 is formed which projects and/or protrudes inwardly in order to receive the tank feed line, not shown, subsequently in a sealed manner.

(8) In order to mount the tank recess 1, the connecting part 12 is initially fastened from inside into the vehicle body opening 11 to the inner metal plate 5 to form the flange 8, as shown in FIG. 1 or the flange 8 is formed integrally with the inner plate 5, as shown in FIG. 2.

(9) Then the recess body 2 is inserted and fastened from the outside onto the outer metal plate 4 of the vehicle body opening 11. In this case, the sealing edge 10 is inserted in a stretched installed position (dashed lines in the figure) into the vehicle body opening 11 so that the sealing edge 10 also penetrates the vehicle body opening 11 on the inner metal part 5 and protrudes beyond the flange 8.

(10) Subsequently from the outside, for example using the finger, the sealing edge 10 is able to be folded over into a final position on the flange 8 for peripheral sealing in the direction of the arrow U (solid lines in the Figures). By the elastic tensioning of the folded-over sealing edge 10, said sealing edge bears tightly and thus sealingly and securely against flange 8.
