Abstract

A connector for a wiper blade, the connector is configured to cooperate pivotably, by a transverse hinge pin, with an adapter designed to allow an articulation link between the blade and a driving arm, the connector includes a body provided with two opposite side flanges, defining a housing designed to receive the adapter, and a pin between the flanges for the articulation link of the blade to the arm, the flanges include, at each of the ends of the hinge pin, a shoulder configured to allow axial guiding of the articulation link between the blade and the arm, the side flanges is configured to allow lateral flexion of the adapter bearing against the shoulder.

Claims

1. A connector for a wiper blade, said connector being configured to cooperate pivotably, by a transverse hinge pin, with an adapter designed to allow an articulation link between said blade and a driving arm, said connector comprising a body provided with two opposite side flanges, defining a housing designed to receive said adapter (9), and a pin (7) between said flanges for said articulation link of the blade to the arm, said flanges (21) comprising, at each of the ends of the hinge pin (7), a shoulder (31) configured to allow axial guiding of said articulation link between the blade and the arm, said side flanges (21) being configured to allow lateral flexion f of the adapter bearing against said shoulder (31).

2. The connector according to claim 1, wherein said shoulder comprises a bearing zone for the axial guidance of said articulation link between the blade and the arm, defining a lateral interval between said shoulder and the corresponding flange of the connector, in which said lateral flexion is exerted.

3. The connector according to claim 1, wherein said shoulder is circular, coaxial to said pin.

4. The connector according to claim 3, wherein said shoulder has a maximum diameter corresponding to a dimension aligned with a bottom of an arm housing of the adapter.

5. The connector according to claim 1, wherein at least one of said side connector flanges is provided with at least one stud able to be applied with play against a corresponding side wing of the adapter.

6. The connector according to claim 5, wherein said stud play is provided to absorb a lateral deformation of the adapter when it receives a driving arm of a windshield wiper system with a dimension larger than a standard dimension.

7. The connector according to claim 5, wherein each of said side connector flanges is provided with at least one stud.

8. The connector according to claim 5, wherein the studs include a slender end section.

9. The connector according to claim 5, wherein there are two of said studs on each of said side flanges, positioned on either side of said hinge pin, at equal distances from said hinge pin.

10. The connector according to claim 5, wherein said studs are rectilinear and extend substantially perpendicular to the hinge Pin.

11. The connector according to claim 5, wherein said studs are positioned across from each other on said side flanges of the connector.

12. The connector according to claim 5, wherein said studs are positioned so as to be located across from side wing lugs of the adapter.

13. A fastening device between a wiper blade and a driving arm for a windshield wiping system of a motor vehicle, comprising:

a connector according to claim 1; and

an adapter of said wiping system.

14. A wiper blade comprising a connector according to claim 1.

15. A wiper system comprising a wiper blade according to claim 14.
