Abstract

A wiper blade with integral washer nozzles including a blade rubber for wiping a glass of a vehicle, a spoiler combined with a retainer of a wiper arm, secondary levers combined with the spoiler, and yokes combined with the secondary levers, respectively, and supporting the blade rubber, may have a washer nozzle module integrally combined with the spoiler and spraying washer fluid supplied through washer fluid hoses in two directions with respect to the spoiler, wherein the washer nozzle module has washer fluid channels formed therein in a longitudinal direction of the spoiler to spray the washer fluid in two directions, nozzles formed along the washer fluid channels and spraying the washer fluid supplied through the washer fluid channels, and inlets communicating with the washer fluid channels, respectively, and connected with the washer fluid hoses for supplying the washer fluid.

First claim

What is claimed is:

1. A wiper blade with integral washer nozzles including a blade rubber for wiping a glass of a vehicle, a spoiler combined with a retainer of a wiper arm, secondary levers directly connected to the spoiler, and yokes directly connected to the secondary levers, respectively, and supporting the blade rubber, the wiper blade comprising:
a washer nozzle module integrally directly connected to the spoiler and spraying washer fluid supplied through washer fluid hoses in two directions with respect to the spoiler,
wherein the washer nozzle module has washer fluid channels formed therein in a longitudinal direction of the spoiler to spray the washer fluid in two directions, nozzles formed along the washer fluid channels and spraying the washer fluid supplied through the washer fluid channels, and inlets communicating with the washer fluid channels, respectively, and connected with the washer fluid hoses for supplying the washer fluid.

2. The wiper blade of claim 1 , wherein the washer nozzle module includes a nozzle body and a nozzle cover that form the washer fluid channels by being combined with each other, parallel channel grooves that communicate with the inlets, respectively, are formed on the nozzle body, and the nozzle cover is combined with the nozzle body and covers bottoms of the channel grooves so that the channel grooves are sealed by the nozzle cover to form the washer fluid channels.

3. The wiper blade of claim 2 , wherein the nozzles protruding for spraying the washer fluid are formed with predetermined intervals on the nozzle cover and arranged at both sides of the spoiler to spray the washer fluid downward from the nozzle cover.

4. The wiper blade of claim 3 , wherein the nozzles are set to spray the washer fluid at an angle back and forth with respect to the longitudinal direction of the nozzle cover.

5. The wiper blade of claim 2 , wherein the nozzle body is integrally combined with the spoiler.

6. The wiper blade of claim 1 , wherein the washer fluid hoses through which the washer fluid is supplied by pumps that are independently driven and controlled are connected to the inlets, respectively, so the washer fluid is sprayed through only the nozzles in any one of the two washer fluid channels while the washer pumps are sequentially driven in accordance with a motion direction of the wiper blade.

7. The wiper blade of claim 1 , wherein the washer nozzle module is coupled to a top of the spoiler and a seat in which the washer nozzle module is seated is formed in a shape of a groove longitudinally on a top of a center spoiler.

8. The wiper blade of claim 7 , wherein the washer nozzle module is seated in the seat of the spoiler by sliding, seat projections are formed on left and right sides of the seat, locking-projections protrude inward at left and right sides of a bottom of the washer nozzle module, so the washer nozzle is combined by sliding such that the locking-projections are fitted in between the seat projections and a seating side of the seat on which the bottom of the washer nozzle module slides.

9. The wiper blade of claim 8 , wherein when the washer nozzle module is combined by sliding, with the locking-projections fitted in between the seating side and the seat projections, a protrusion form in the seat of the spoiler is inserted in a fitting hole of the washer nozzle module to restrict the washer nozzle module.
