WINDSCREEN WIPER DEVICE

1 . A windscreen wiper device, comprising:

a wiper blade of a flexible material;

connecting device for attachment with an oscillating wiper arm;

said connecting device including a base and a joint part which is pivotably attached with said base;

said joint part including a main body portion which extends in a longitudinal direction between opposite longitudinal ends, said joint part further including a front nose portion positioned adjacent one longitudinal end of said main body portion, and said joint part further including a rear portion positioned at an opposite longitudinal end of said main body portion from said front nose portion;

said rear portion including a pair of lugs which extend in opposite lateral directions for receiving legs on the oscillating wiper arm; and

said lugs being generally cylindrical in shape for allowing easy rotation of said joint part relative to the legs of the oscillating wiper arm during attachment and detachment of said connecting device with the oscillating wiper arm.

2 . The windscreen wiper device as set forth in claim 1 wherein said lugs are connected with said main body portion via at least one bridge.

3 . The windscreen wiper device as set forth in claim 2 wherein said at least one bridge is a pair of bridges which diverge away from one another from said main body portion.

4 . The windscreen wiper device as set forth in claim 1 wherein said main body portion and said rear portion are generally U-shaped with a top wall and a pair of side walls and wherein said cylindrical lugs extend laterally from said side walls.

5 . The windscreen wiper device as set forth in claim 1 wherein said front nose portion includes a pair of longitudinally extending fingers for lockingly engaging a top edge of at least one style of oscillating wiper arm.

6 . The windscreen wiper device as set forth in claim 5 wherein said front nose portion is connected with said main body portion via a living hinge for allowing said front nose portion to pivot relative to said main body portion.

7 . The windscreen wiper device as set forth in claim 6 wherein said fingers of said front nose portion are spaced laterally from one another by a U-shaped opening for allowing a tongue on one style of oscillating wiper arm to pass between said fingers during attachment and detachment of said joint part with the oscillating wiper arm.

8 . The windscreen wiper device as set forth in claim 1 wherein said main body portion has a top wall with a resilient tab and a button formed therein for lockingly engaging within an opening of one style of oscillating wiper arm.

9 . A method of attaching a windscreen wiper device with an oscillating wiper arm, comprising the steps of:

providing a windscreen wiper device with a connecting device that has a one-piece joint part with a main body portion which extends in a longitudinal direction and a front nose portion and a rear portion, the front nose portion being pivotable relative to the main body portion at a living hinge, and the rear portion presenting a pair of laterally extending lugs with cylindrical shapes;

contacting each of the cylindrical lugs of the joint part with the oscillating wiper arm at two points of contact with one of the points of contact being between the cylindrical lug and a back surface of a leg on the oscillating wiper arm and with the other point of contact being between the cylindrical lug and a lower edge of the oscillating wiper arm;

pivoting the joint part relative to the oscillating wiper arm about the cylindrical lugs; and

lockingly engaging the front nose portion of the joint part with the oscillating wiper arm.
