Wiper blade with connector and method for making such blade

1. A wiper blade comprising:

a bearing structure in which a flexible vertebra is longitudinally inserted, wherein the bearing structure comprises, on corresponding sides, openings exposing side edges of the flexible vertebra; and

a connector that is fitted substantially transversally onto the bearing structure at the level of the openings and that is blocked in terms of movement in the fitting direction thereof by portions of the side edges protruding from said openings,

wherein the connector includes at least one deformation extending inside a notch formed in the vertebra at a portion of a side edge and accessible via one of the openings of the bearing structure.

2. The wiper blade according to claim 1 , wherein at least one notch is formed on each side edge of the vertebra and wherein the deformation extends inside each notch.

3. The wiper blade according to claim 1 , wherein at least two notches, symmetrical with respect to each other, are respectively formed on each side edge of the vertebra, and wherein a deformation extends inside each notch.

4. The wiper blade according to claim 1 , wherein at least one notch of the vertebra is formed opposite an opening of the bearing structure, exclusively dedicated to the access thereof.

5. The wiper blade according to claim 1 , wherein at least one notch of the vertebra has a size substantially identical to that of the opening which is associated therewith.

6. The wiper blade according to claim 1 , wherein at least one notch extends on the whole thickness of the vertebra.

7. The wiper blade according to claim 1 , wherein that the connector is made of a thermoplastic material.

8. The wiper blade according to claim 1 , wherein the wiper blade is used in a motor vehicle.

9. A method for making a wiper blade including a bearing structure in which a flexible vertebra is longitudinally inserted, and on corresponding sides of which are formed openings exposing side edges on the vertebra, as well as a connector fitted substantially transversally onto the bearing structure at the level of the openings, wherein the connector is locked in terms of movement in the fitting direction thereof by portions of the side edges protruding from said openings, the method comprising:

deforming at least one portion of the connector, creating a deformation until the connector enters a notch which is formed on the vertebra at the level of the portion of a side edge and accessible via one of the openings of the bearing structure.

10. The method according to claim 9 , wherein deforming the at least one portion of the connector further comprises forming, on each side of the connector, at least one deformation which cooperates with a notch formed at the level of a matching side edge of the vertebra.

11. The method according to claim 9 , wherein deforming the at least one portion of the connector further comprises forming, on the connector, at least two deformations which are substantially symmetrical with respect to each other in the plane of the wiper blade, wherein the at least two deformations cooperate with two notches formed substantially opposite each other on either side of the vertebra.

12. The method according to claim 9 , wherein each deformation is provided along a direction substantially perpendicular to the body of the wiper blade.

13. The method according to claim 9 , wherein each deformation is provided according to a direction substantially parallel to the plane of the wiper blade.

14. The method according to claim 9 , wherein each deformation is provided after the positioning and the blocking of the connector on the bearing structure.

15. The method according to claim 9 , wherein each deformation is provided by ultrasonic welding.

16. The method according to claim 9 , wherein each deformation is provided by hot forming.

17. The method according to claim 9 , wherein each deformation is provided by cold forming.
