Abstract

A streamlined flat windscreen wiper for a vehicle is disclosed. The flat wiper includes a longitudinal wiper blade, at least one longitudinal stiffening member, a longitudinal member for retaining the wiper blade and the stiffening member, a longitudinal streamlined portion comprising two terminal caps and a central mounting extending between the terminal caps and being connected thereto. The mounting has means for fixing to the stiffening member or to the member for retaining the stiffening member, and each cap includes means for guiding in translation terminal parts of said member.

First claim

The invention claimed is:

1. A streamlined flat windscreen wiper for a vehicle, comprising:
a longitudinal wiper blade;
at least one longitudinal stiffening member;
a longitudinal retaining member for retaining said wiper blade and said stiffening member; and
a longitudinal streamlined portion comprising two terminal caps and a central mounting extending between the terminal caps and being connected thereto,
wherein the central mounting comprises fixing means for fixing to said stiffening member or to said longitudinal retaining member,
wherein each terminal cap comprises means for guiding in translation terminal ends of said longitudinal retaining member or said longitudinal stiffening member, and
wherein said longitudinal retaining member and said longitudinal stiffening member are configured to glide freely with respect to the means for guiding in translation in an assembled configuration.

2. The wiper according to claim 1 , wherein the central mounting comprises at each of its longitudinal ends means for articulation of the corresponding terminal cap.

3. The wiper according to claim 1 , wherein the central mounting comprises an aperture which is configured to receive an adapter for connecting the wiper to a drive arm of said wiper.

4. The wiper according to claim 3 , wherein the aperture has an elongated shape and extends between two longitudinal lateral walls of the central mounting, a pivot pin of said adapter extending therebetween.

5. The wiper according to claim 1 , wherein the longitudinal retaining member comprises a first longitudinal housing for receiving a heel of the wiper blade and a second longitudinal housing for receiving the stiffening member.

6. The wiper according to claim 5 , wherein the stiffening member bears against the heel of the blade or is separated from said heel by a longitudinal wall of said longitudinal retaining member.

7. The wiper according to claim 1 , the at least one longitudinal stiffening member comprising a single stiffening member.

8. The wiper according to claim 1 , wherein at least one of the elements from the central mounting and the caps forms or comprises an aerodynamic baffle.

9. The wiper according to claim 1 , wherein at least one of the elements from the central mounting and the caps comprises two longitudinal lateral walls, the first longitudinal edges thereof being connected together so that said walls form substantially a dihedron over at least one longitudinal part of said element.

10. The wiper according to claim 9 , wherein the dihedron defines an upper longitudinal edge of the central mounting or of the cap.

11. The wiper according to claim 10 , wherein said edge extends substantially parallel to and spaced apart from a central longitudinal plane of the fixing means for fixing the central mounting to said stiffening member or to said longitudinal retaining member.

12. The wiper according to claim 9 , wherein said longitudinal lateral walls comprise, opposite said first longitudinal edges, second longitudinal edges which are free or connected to longitudinal lateral flanges.

13. The wiper according to claim 12 , wherein the second longitudinal edge of one of said longitudinal lateral walls is substantially located in a first substantially horizontal longitudinal plane which is remote from a second substantially horizontal longitudinal plane passing substantially through the second longitudinal edge of the other of said longitudinal lateral walls.

14. The wiper according to claim 12 , wherein said means for guiding extend between said lateral flanges.

15. The wiper according to claim 14 , wherein said lateral flanges are connected together by a transverse wall, a passage for the guidance of said longitudinal retaining member being formed therein.

16. The wiper according to claim 1 , wherein:
the means for guiding in translation comprise at least two lateral guide hooks that extend from lateral flanges of each of the two terminal end caps, and
the terminal ends of the longitudinal retaining member or the longitudinal stiffening member are slidable within the longitudinal streamlined portion when connected with the at least two lateral guide hooks.
