Abstract

The invention relates to a tube holder for a wiper arm, comprising a bracket, a positively locking closure and a tube receptacle as well as a wiper receptacle, wherein the bracket can be folded onto the tube receptacle so that the wiper receptacle can be closed by the bracket, the bracket being fixed onto the wiper receptacle by means of the closure.

First claim

What is claimed is:

1. A tube holder ( 10 ) for a wiper arm ( 12 ), comprising a bracket ( 14 ), a positively locking closure ( 16 ) and a tube receptacle ( 18 ) and a wiper receptacle ( 20 ), wherein the bracket ( 14 ) is configured to be folded onto the wiper receptacle ( 20 ) so that the wiper receptacle ( 20 ) is closed by the bracket ( 14 ) and the bracket ( 14 ) is fixed on the wiper receptacle ( 20 ) by the closure ( 16 ) wherein the wiper receptacle ( 20 ) includes a base ( 21 ) and a flexible lateral stop ( 22 ) extending from the base ( 21 ), wherein the stop ( 22 ) is in a first rotational position relative to the base when the bracket ( 14 ) is in an opened state, wherein the bracket ( 14 ) is configured to be rotated to bear against the stop ( 22 ) in a closed state, wherein the bracket presses and rotate the stop ( 22 ) into a second rotational position relative to the base, such that the stop is pressed against the wiper arm ( 12 ) when the bracket is in the closed state.

2. The tube holder ( 10 ) according to claim 1 , characterized in that the wiper receptacle ( 20 ) is a cavity ( 200 ) between the bracket ( 14 ) and the tube receptacle ( 18 ), wherein the base ( 21 ) lies opposite the bracket ( 14 ) with respect to the cavity ( 200 ).

3. The tube holder ( 10 ) according to claim 2 , characterized in that a nose ( 34 ) is arranged on a side of the bracket ( 14 ) facing the cavity ( 200 ), said nose projecting into the wiper receptacle ( 20 ).

4. The tube holder ( 10 ) according to claim 2 , characterized in that the tube receptacle ( 18 ) includes two extensions ( 36 ), which, starting from the base ( 21 ), extend away from the wiper receptacle ( 20 ), wherein a circular recess ( 38 ) is substantially formed between the extensions ( 36 ), wherein a diameter of the recess ( 38 ) is greater than a distance between free ends ( 40 ) of the extensions ( 36 ).

5. The tube holder ( 10 ) according to claim 4 , characterized in that one of the extensions ( 36 ) continuously passes into the bracket ( 14 ).

6. The tube holder ( 10 ) according to claim 4 , characterized in that the extensions ( 36 ) deviate from a circular shape thereof and comprise straight sections.

7. The tube holder ( 10 ) according to claim 2 , characterized in that a nose ( 34 ) is arranged on a side of the bracket ( 14 ) facing the cavity ( 200 ), said nose projecting into the wiper receptacle ( 20 ), wherein the nose ( 34 ) is arranged on a section ( 140 ) of the bracket ( 14 ), which lies opposite and approximately parallel to the base ( 21 ).

8. The tube holder ( 10 ) according to claim 1 , characterized in that the bracket ( 14 ) bears against the stop ( 22 ) from an outside in the closed state.

9. The tube holder ( 10 ) according to claim 1 , characterized in that, on a side of the bracket ( 14 ) which faces the wiper receptacle ( 20 ), a brace ( 26 ) is laterally formed which lies opposite the stop ( 22 ), wherein a closed space ( 28 ) is formed between the bracket ( 14 ) and the brace ( 26 ).

10. The tube holder ( 10 ) according to claim 1 , characterized in that the closure ( 16 ) is configured in a hook-shaped manner, wherein a bracket hook ( 160 ) is disposed at a free end ( 30 ) of the bracket ( 14 ) and a base hook ( 161 ) is disposed at a free end ( 32 ) of the base so that, in the closed state, the bracket hook ( 160 ) engages around the base hook ( 161 ).

11. The tube holder ( 10 ) according to claim 10 , characterized in that the base hook ( 161 ) is arranged laterally and lies opposite the stop ( 22 ).

12. The tube holder ( 10 ) according to claim 1 , characterized in that the tube holder ( 10 ) has an edge ( 44 ) at axial ends ( 42 ) thereof, said edge being directed radially outwards, wherein the edge ( 44 ) has a radius ( 46 ).

13. The tube holder ( 10 ) according to claim 1 , characterized in that the tube holder ( 10 ) comprises a flexible plastic.

14. A wiper arm ( 12 ) having a tube holder ( 10 ) according to claim 1 , said wiper arm being mounted on a motor vehicle ( 1 ).

15. A method for producing a tube holder ( 10 ) according to claim 1 , characterized in that the tube holder ( 10 ) is extruded or injection molded.

16. A wiper assembly comprising a tube holder according to claim 1 and a wiper arm enclosed within the wiper receptacle of the tube holder, wherein the bracket ( 14 ) is folded onto the wiper receptacle ( 20 ) so that the wiper receptacle ( 20 ) is closed by the bracket ( 14 ) and the bracket ( 14 ) is fixed on the wiper receptacle ( 20 ) by the closure ( 16 ).

17. The tube holder ( 10 ) according to claim 1 , characterized in that the wiper receptacle ( 20 ) is a cavity ( 200 ) between the bracket ( 14 ) and the tube receptacle ( 18 ), wherein the base ( 21 ) lies opposite and partially parallel to the bracket ( 14 ) with respect to the cavity ( 200 ).

18. The tube holder ( 10 ) according to claim 1 , characterized in that the stop ( 22 ) has a free end ( 24 ).

19. The tube holder ( 10 ) according to claim 1 , characterized in that, on a side of the bracket ( 14 ) which faces the wiper receptacle ( 20 ), a flexible brace ( 26 ) is laterally formed which lies opposite the stop ( 22 ), wherein a closed space ( 28 ) is formed between the bracket ( 14 ) and the brace ( 26 ).

20. The tube holder according to claim 1 , wherein the flexible lateral stop ( 22 ) extends generally transversely to the base in the second rotational position.

21. The tube holder according to claim 1 , wherein the positively locking closure ( 16 ) is spaced separately away from the stop ( 22 ).
