Abstract

A windscreen wiper device, or a wiper blade assembly, for cleaning a windshield of a vehicle is provided. The wiper blade assembly includes a wiper strip that extends in a longitudinal direction and at least one carrier element in engagement with the wiper strip for supporting and biasing the wiper strip into a predetermined configuration. An at least two piece connecting device is coupled to the at least one carrier element. One piece of the connecting device is a main piece that has a bearing surface shaped, and the other piece is a door piece that is pivotable between an open position for allowing attachment and detachment between the connecting device and the wiper arm and a closed position for securing the wiper arm into engagement with the wiper blade assembly. The door piece is pivotably coupled to the main piece about an axis that extends in a longitudinal direction.

Claims

1. A windscreen wiper device for cleaning a windshield of a vehicle, comprising:

a wiper strip extending in a longitudinal direction;

at least one carrier element in engagement with said wiper strip for operatively supporting and biasing said wiper strip into a predetermined configuration;

an at least two piece connecting device operatively coupled to said at least one carrier element and including a main piece with a bearing surface shaped for receiving and operatively supporting an end of a hook style wiper arm and a door piece pivotably coupled to said main piece and wherein said door piece is pivotable between an open position for allowing attachment and detachment between said connecting device and the wiper arm and a closed position for securing the wiper arm into engagement with said windscreen wiper device;

wherein said main piece is formed as a separate and distinct piece from that of the door piece, and wherein said main piece and said door piece include hinge portions that are arranged and mechanically interlock in such manner that said door piece is pivotably coupled to said main piece about an axis of said hinge portions that extends in said longitudinal direction;

wherein said door piece includes a tongue which projects from a top wall of said door piece;

said tongue presenting a retaining surface that is spaced a predetermined distance from and faces said bearing surface when said door piece is in said closed position for trapping a portion of the hook-shaped end of the wiper arm between said retaining surface and said bearing surface; and

wherein said door piece includes side walls that are laterally spaced from one another, and a further support wall that is arranged between and spaced from said side walls and that extends transversely to and directly engages and supports said tongue.

2. The windscreen wiper device as set forth in claim 1 wherein one of said main and door pieces includes a pin extending along said longitudinal axis and the other includes a generally claw shaped receiver engaging at least partially around said pin to establish said pivoting connecting between said door and main pieces.

3. The windscreen wiper device as set forth in claim 2 further including an enlarged piece at the end of said pin for restricting removal of said receiver from said pin.

4. The windscreen wiper device as set forth in claim 3 wherein said enlarged piece is also coupled with one of said side walls of said main piece.

5. The windscreen wiper device as set forth in claim 2 wherein main piece includes a pair of side walls and wherein said pin is integrally coupled to and extends forwardly away from one of said side walls and wherein said claw shaped receiver is disposed on said door piece.

6. The windscreen wiper device as set forth in claim 1 wherein said retaining surface on said door piece is on said tongue that extends generally downwardly when said door piece is in said closed position.

7. The windscreen wiper device as set forth in claim 1 wherein said bearing surface extends transversely between said side walls.

8. The windscreen wiper device as set forth in claim 7 wherein one of said side walls of said main piece includes a tab with a window and wherein said door piece includes a projection shaped to be received within said window to establish a locking relationship between said door piece and said main piece.

9. The windscreen wiper device as set forth in claim 8 wherein said main piece includes a pin disposed on said side wall opposite of said window and wherein said door piece includes a claw shaped receiver disposed opposite of said projection and engaged partially around said pin of said main piece to establish said pivoting relationship between said door piece and said main piece.

10. The windscreen wiper device as set forth in claim 1 further including a base permanently secured to said at least one carrier element and wherein said connecting device is removably coupled to said base.

11. The windscreen wiper device as set forth in claim 10 wherein said base includes a tubular portion and wherein said connecting device includes a pair of apertures receiving said tubular portion to establish a pivoting relationship between said base and said connecting device.
