Abstract

A charging housing or filler neck housing for insertion into a body opening in a motor vehicle comprises a housing body with a passage opening. A plug-in charging connector or a tank filler pipe can be inserted into the passage opening, and a sealing ring is arranged on the passage opening. The sealing ring has an annular sealing body, from which a first elastic sealing lip and a second elastic sealing lip extend, wherein the first sealing lip is designed to bear against a plug-in charging connector or tank filler pipe inserted into the passage opening, and wherein the second sealing lip is designed to bear against a closure flap closing the filler neck housing or charging housing.

First claim

What is claimed is:

1. A charging housing or filler neck housing for insertion into a body opening in a motor vehicle, comprising:
a housing body with a passage opening into which a plug-in charging connector or a tank filler pipe can be inserted;
a sealing ring arranged on the passage opening, wherein the sealing ring has an annular sealing body from which a first elastic sealing lip and a second elastic sealing lip extend, wherein the first sealing lip is designed to bear against the plug-in charging connector or tank filler pipe inserted into the passage opening, and wherein the second sealing lip is designed to bear against a closure flap closing the filler neck housing or charging housing.

2. The charging housing or filler neck housing according to claim 1 , wherein the first and second elastic sealing lips extend in opposite directions from the annular sealing body.

3. The charging housing or filler neck housing according to claim 1 , wherein the annular sealing body is injection moulded in a two-component injection-moulding process onto an edge bounding the passage opening in the housing body.

4. The charging housing or filler neck housing according to claim 1 , wherein the sealing ring is mounted in a floating manner on the passage opening in the housing body.

5. The charging housing or filler neck housing according to claim 1 , wherein at least one of:
the first elastic sealing lip bears against a stop of the plug-in charging connector or tank filler pipe when the plug-in charging connector or tank filler pipe is inserted into the passage opening; or
the second elastic sealing lip bears against a stop of the closure flap when the closure flap is closed.

6. The charging housing or filler neck housing according to claim 4 , wherein one of:
the annular sealing body has a slot that encircles said annular sealing body on an outer side thereof and in which an edge bounding the passage opening in the housing body is accommodated in a floating manner; or
the edge bounding the passage opening in the housing body has an encircling slot in which the annular sealing body is accommodated in a floating manner.

7. The charging housing or filler neck housing according to claim 4 , further comprising:
a carrier ring mounted in a floating manner on an edge bounding the passage opening in the housing body, wherein the sealing body is arranged on the carrier ring.

8. The charging housing or filler neck housing according to claim 7 , wherein the annular sealing body is injection moulded in a two-component injection-moulding process onto the carrier ring.

9. The charging housing or filler neck housing according to claim 7 , wherein one of:
the carrier ring has a slot that encircles an outer side thereof and in which the edge bounding the passage opening in the housing body is accommodated in a floating manner; or
the edge bounding the passage opening in the housing body has an encircling slot in which the carrier ring is accommodated in a floating manner.

10. The charging housing or filler neck housing according to claim 7 , wherein the carrier ring is connected via a bayonet connection to the edge bounding the passage opening in the housing body.

11. The charging housing or filler neck housing according to claim 1 , further comprising:
the closure flap connected to the housing body so as to be pivotable between an open position opening up the charging housing or filler neck housing and a closed position closing the charging housing or filler neck housing.

12. The charging housing or filler neck housing according to claim 11 , wherein the closure flap comprises a hinge arm via which said closure flap is connected pivotably to the housing body.

13. The charging housing or filler neck housing according to claim 11 , wherein the closure flap has an encircling splash wall facing the housing body.

14. The charging housing or filler neck housing according to claim 1 , further comprising:
the plug-in charging connector inserted into the passage opening of the housing body or the tank filler pipe inserted into the passage opening in the housing body.

15. A motor vehicle comprising the charging housing or filler neck housing according to claim 1 inserted into the body opening in the motor vehicle.

16. A charging housing or filler neck housing for insertion into a body opening in a motor vehicle, comprising:
a housing body with a passage opening; and
an elastic sealing ring comprising:
an annular sealing body arranged about an edge bounding the passage opening of the housing body;
a first sealing lip extending from the annular sealing body and having an outer end designed to contact a plug-in charging connector or a tank filler pipe inserted into the passage opening; and
a second elastic sealing lip extending from the annular sealing body and having an outer end designed to contact a closure flap covering the passage opening.

17. The charging housing or filler neck housing of claim 16 , further comprising:
the closure flap comprising a hinge arm and a central flap section, the outer end of the second sealing lip in contact with the central flap section of the closure flap.

18. The charging housing or filler neck housing of claim 16 , wherein the annular sealing body comprises a slot extending away from the passage opening and surrounding the edge bounding the passage opening.

19. The charging housing or filler neck housing of claim 16 , further comprising:
an annular carrier ring arranged on the edge bounding the passage opening, the annular sealing body in contact with the annular carrier ring.

20. The charging housing or filler neck housing of claim 19 , wherein the annular carrier ring comprises a slot extending away from the passage opening and surrounding the edge bounding the passage opening.
