Abstract

Adapter for a windscreen wiper, in particular a motor vehicle windscreen wiper, said adapter being intended to connect a wiper blade ( 12 ) to an end piece ( 28 ′) of a first driving arm ( 14 ′), of the laterally locking type that is secured to a cylindrical rod ( 33 ) that defines an articulation axis of the adapter with respect to said blade, said adapter comprising a longitudinal body comprising two substantially parallel first longitudinal lateral wall that are connected together by a transverse wall, said body being connected at one longitudinal end to a cowling ( 46 ) that has a transverse dimension larger than said body, characterized in that said body has, at a longitudinal distance from said cowling, a transverse orifice ( 45 ) configured to receive said cylindrical rod, and in that said cowling comprises, on a first side of said adapter, a lateral face configured to cooperate with said end piece by bearing.

First claim

The invention claimed is:

1. An adapter for a motor vehicle windscreen wiper, said adapter being for connecting a wiper blade to an end piece of a first driving arm, of the laterally locking type that is secured to a cylindrical rod that defines an articulation axis of the adapter with respect to said blade, said adapter comprising:
a longitudinal body comprising two substantially parallel first longitudinal lateral walls that are connected together by a transverse wall, said body being connected at one longitudinal end to a cowling that has a transverse dimension larger than that of said body,
wherein said body has, at a longitudinal distance from said cowling, a transverse orifice configured to receive said cylindrical rod, and wherein said cowling comprises, on a first side of said adapter, a first lateral face configured to cooperate with said end piece by bearing,
wherein said longitudinal body comprises a transverse groove which extends in said transverse wall, over the entire transverse length of said transverse wall, in a direction parallel to the orifice, between said first longitudinal lateral walls, and
wherein the transverse groove is configured to receive an L-shaped lateral tab of the end piece.

2. The adapter according to claim 1 , wherein said cowling comprises two second longitudinal lateral walls, one of which comprises said lateral face.

3. The adapter according to claim 2 , wherein said second lateral walls are connected together by at least one transverse wall.

4. The adapter according to claim 2 , wherein said second lateral walls extend at least in part in a manner facing said first walls and are spaced apart from said first walls so as to define at least one housing intended to receive a longitudinal end of an end piece of a second driving arm having a substantially U-shaped cross section.

5. The adapter according to claim 2 , wherein said second lateral walls define a first longitudinal end portion of width L 1 and a second, opposite longitudinal end portion of width L 2 , which is less than L 1 and greater than the width of said body.

6. The adapter according to claim 5 , wherein said first portion is situated between said body and said second portion.

7. The adapter according to claim 1 , wherein said second lateral walls each comprise at least one protruding tab that extends longitudinally from the side of said body.

8. The adapter according to claim 7 , wherein each protruding tab has a height substantially less than or equal to that of said body.

9. The adapter according to claim 1 , wherein said body comprises, on a second side of said adapter, away from said first side, a second lateral face configured to cooperate with said end piece by bearing.

10. The adapter according to claim 9 , wherein said first lateral walls comprise protruding ribs on external lateral faces.

11. The adapter according to claim 10 , wherein one of said ribs defines said second lateral face of the body.

12. The adapter according to claim 1 , wherein said groove extends close to a transverse plane that is perpendicular to a longitudinal axis of the adapter and passes substantially through said orifice.

13. The adapter according to claim 1 , wherein said body comprises elastically deformable means for elastic snap-fitting.

14. The adapter according to claim 13 , wherein said means comprise at least one actuation button that is situated in a hole or slot in said transverse wall.

15. An assembly comprising an adapter according to claim 1 and a driving arm, for a motor vehicle windscreen wiper.

16. The assembly according to claim 15 , wherein said arm is of the laterally locking type and is secured to a cylindrical rod, said arm having a lateral wall configured to cooperate with said first lateral face of said cowling by bearing and/or sliding, and an L-shaped tab, one lip of which defines a lateral bearing face configured to cooperate with a second lateral face of said body by bearing and/or sliding.

17. An assembly comprising:
an adapter according to claim 1 ; and
a blade for a motor vehicle windscreen wiper.
