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.

First claim

The invention claimed is:

1. A connector assembly for a wiper blade, the connector assembly comprising:
an adapter comprising two opposite side wings configured to receive between them an end of a driving arm,
wherein the side wings laterally flex outward to provide sufficient space to accommodate the end of the driving arm,
wherein the adapter has an opening at a first end that extends in a longitudinal direction parallel to the side wings and extending approximately the length of the side wings; and
a connector, wherein said connector is configured to cooperate pivotably, by a transverse hinge pin, with the adapter designed to allow an articulation link between said blade and the driving arm, said connector comprising:
a body provided with two opposite side flanges, defining a housing designed to receive said adapter; and
the transverse hinge pin between said flanges for said articulation link of the blade to the arm,
wherein said flanges comprise, at each of the ends of the transverse hinge pin, a shoulder configured to allow axial guiding of said articulation link between the blade and the arm, said side flanges being configured to allow on both sides of said transverse hinge pin the lateral flexion of the side wings of the adapter that bears against said shoulder.

2. The connector assembly 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 assembly according to claim 1 , wherein said shoulder is circular, coaxial to said transverse hinge pin.

4. The connector assembly 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 assembly 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 assembly according to claim 5 , wherein the at least one stud is applied with play 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 assembly according to claim 5 , wherein each of said side connector flanges is provided with at least one stud.

8. The connector assembly according to claim 5 , wherein the at least one stud includes a slender end section.

9. The connector assembly according to claim 5 , wherein the at least one stud is rectilinear and extend substantially perpendicular to the transverse hinge pin.

10. The connector assembly according to claim 5 , wherein the at least one stud is positioned across from each other on said side flanges of the connector.

11. The connector assembly according to claim 5 , wherein the at least one stud is positioned so as to be located across from side wing lugs of the adapter.

12. A connector for a wiper blade, the connector being 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 comprising:
a body provided with two opposite side flanges, defining a housing designed to receive the adapter; and
the transverse hinge pin between the flanges for the articulation link of the blade to the arm,
wherein the flanges comprises, at each of the ends of the transverse hinge pin, a shoulder configured to allow axial guiding of the articulation link between the blade and the arm, the side flanges being configured to allow lateral flexion of the adapter bearing against the shoulder,
wherein two studs are provided on each of the side flanges,
wherein the two studs are identical to each other and include a slender end section; configured to reduce the rubbing on the side wings;
wherein the two studs are able to be applied with play against a corresponding side wing of the adapter, and
wherein the two studs are positioned on opposite sides of said transverse hinge pin at equal distances from said transverse hinge pin.

13. A wiper system comprising: a wiper blade; and a connector assembly, the connector assembly comprising:
an adapter comprising two opposite side wings configured to receive between them an end of a driving arm,
wherein the side wings laterally flex outward to provide sufficient space to accommodate the end of the driving arm,
wherein the adapter has an opening at a first end that extends in a longitudinal direction parallel to the side wings and extending approximately the length of the side wings; and
a connector, wherein said connector is configured to cooperate pivotably, by a transverse hinge pin, with the adapter designed to allow an articulation link between said blade and the driving arm, said connector comprising:
a body provided with two opposite side flanges, defining a housing designed to receive said adapter; and
the transverse hinge pin between said flanges for said articulation link of the blade to the arm,
wherein said flanges comprise, at each of the ends of the transverse hinge pin, a shoulder configured to allow axial guiding of said articulation link between the blade and the arm, said side flanges being configured to allow on both sides of said transverse hinge pin the lateral flexion of the side wings of the adapter that bears against said shoulder.
