Abstract

A filler neck housing arrangement for mounting on a body opening of a motor vehicle includes a housing body ( 12 ) which forms a passage opening for the insertion of at least one tank filler pipe. An annular sealing and holding body ( 10 ) is configured for holding the sealing and holding body on the body opening and for holding the sealing and holding body on the housing body. The sealing and holding body includes a first sealing member which, in the state of the sealing and holding body being held on the body opening, lies in a sealing manner against a surface ( 30 ) of a body part ( 28 ) bounding the body opening, and a second sealing member which, in the state of the sealing and holding body being held on the housing body, lies in a sealing manner against the housing body ( 12 ).

First claim

The invention claimed is:

1. A filler neck housing arrangement for mounting on a body opening of a motor vehicle, comprising a housing body ( 12 ) which forms a passage opening for the insertion of at least one tank filler pipe, an annular sealing and holding body ( 10 ) which has first holding means for holding the sealing and holding body ( 10 ) on the body opening and second holding means for holding the sealing and holding body ( 10 ) on the housing body ( 12 ), wherein the first holding means are provided with first sealing means wherein, when the first holding means holds the sealing and holding body ( 10 ) on the body opening, the first sealing means lie in a sealing manner against a surface of a body part ( 28 ) bounding the body opening, and wherein the second holding means are provided with second sealing means wherein, when the second holding means holds the sealing and holding body ( 10 ) on the housing body ( 12 ), the second sealing means lie in a sealing manner against the housing body ( 12 ).

2. The filler neck housing arrangement as claimed in claim 1 , wherein the first holding means comprise a first holding ring ( 20 ) made of plastic with first latching means for latching on the body opening, and the first sealing means comprise an annular first sealing lip ( 24 ) which is made of plastic and is integrally formed on the first holding ring ( 20 ), wherein the first sealing lip ( 24 ) is composed of a softer plastic than the first holding ring ( 20 ).

3. The filler neck housing arrangement as claimed in claim 2 , wherein the first latching means have a plurality of latching hooks ( 22 ), wherein, when the first holding means holds the sealing and holding body ( 10 ) on the body opening, the latching hooks ( 22 ) lie on an upper side ( 26 ), which faces the housing body ( 12 ), of the body part ( 28 ) bounding the body opening, and the surface against which the first sealing lip ( 24 ) lies is located on a lower side ( 30 ), which faces away from the housing body ( 12 ), of the body part ( 28 ) bounding the body opening.

4. The filler neck housing arrangement as claimed in claim 2 , wherein the second holding means comprise a second holding ring ( 32 ) made of plastic with second latching means for latching to the housing body ( 12 ), and the second sealing means comprise an annular second sealing lip ( 36 ) which is made of plastic and is integrally formed on the second holding ring ( 32 ), wherein the second sealing lip ( 36 ) is composed of a softer plastic than the second holding ring ( 32 ).

5. The filler neck housing arrangement as claimed in claim 4 , characterized in that latching means corresponding to the second latching means of the second holding ring ( 32 ) are provided on the housing body ( 12 ).

6. The filler neck housing arrangement as claimed in claim 4 , wherein the first holding ring ( 20 ) and the second holding ring ( 32 ) are connected to each other by a compensating ring ( 38 ) which is composed of plastic and is integrally formed on the first holding ring ( 20 ) on one side and on the second holding ring ( 32 ) on the other side, wherein the compensating ring ( 38 ) is composed of a softer plastic than the first holding ring ( 20 ) and the second holding ring ( 32 ).

7. The filler neck housing arrangement as claimed in claim 6 , wherein the compensating ring ( 38 ) is composed of the same material as the second sealing lip ( 36 ).

8. The filler neck housing arrangement as claimed in claim 7 , wherein the compensating ring ( 38 ) is connected integrally to the second sealing lip ( 36 ).

9. The filler neck housing arrangement according to claim 1 , wherein, in the passage opening of the housing body ( 12 ), a holding portion ( 40 ) which, in a mounted state, lies against the at least one tank filler pipe is arranged on the housing body ( 12 ).

10. The filler neck housing arrangement as claimed in claim 9 , wherein the holding portion ( 40 ) has two openings which are provided to lie against a respective tank filler pipe.

11. The filler neck housing arrangement according to claim 1 , wherein the body part ( 28 ) forming the body opening is an inner body part ( 28 ) of the motor vehicle, and the housing body ( 12 ) has third holding means with which the housing body ( 12 ) can be held on a further body opening, wherein the further body opening is formed by an outer body part of the motor vehicle.

12. The filler neck housing arrangement according to claim 1 , wherein the sealing and holding body ( 10 ) is produced in a two-component injection-molding process.

13. The filler neck housing arrangement according to claim 1 , wherein the filler neck housing is mounted on the body opening.

14. A filler neck housing assembly for mounting on a body opening of a motor vehicle, the assembly comprising a housing body ( 12 ) which forms a passage opening for the insertion of at least one tank filler pipe, an annular sealing and holding body ( 10 ) which is configured for both holding the sealing and holding body ( 10 ) on the body opening and for holding the sealing and holding body ( 10 ) on the housing body ( 12 ), wherein the annular sealing and holding body ( 10 ) includes a first sealing member which, in a state of the sealing and holding body being held on the body opening, lies in a sealing manner against a surface of a body part ( 28 ) bounding the body opening, and wherein the annular sealing and holding body includes a second sealing member which, in a state of the sealing and holding body being held on the housing body ( 12 ), lies in a sealing manner against the housing body ( 12 );
wherein the sealing and holding body includes a first holding ring ( 20 ) made of plastic with at least a first latch for latching on the body opening, and in that the first sealing member comprises an annular first sealing lip ( 24 ) which is made of plastic and is integrally formed on the first holding ring ( 20 ), wherein the first sealing lip ( 24 ) is composed of a softer plastic than the first holding ring ( 20 ).

15. The filler neck housing arrangement as claimed in claim 14 , wherein the first latch comprises a plurality of latching hooks ( 22 ), wherein, in the state held on the body opening, the latching hooks ( 22 ) lie on an upper side ( 26 ), which faces the housing body ( 12 ), of the body part ( 28 ) bounding the body opening, and the surface against which the first sealing lip ( 24 ) lies is located on a lower side ( 30 ), which faces away from the housing body ( 12 ), of the body part ( 28 ) bounding the body opening.

16. The filler neck housing arrangement as claimed in claim 15 , wherein the sealing and holding body includes a second holding ring ( 32 ) made of plastic with at least a second latch for latching to the housing body ( 12 ), and the second sealing member comprises an annular second sealing lip ( 36 ) which is made of plastic and is integrally formed on the second holding ring ( 32 ), wherein the second sealing lip ( 36 ) is composed of a softer plastic than the second holding ring ( 32 ).
