Abstract

injection positions (A 2 , B 2 , and C 2 ) toward which washer liquids (W) are injected from the forward-side injection nozzles (A 1 , B 1 , and C 1 ) and injection positions (D 2 and E 2 ) which washer liquids (W) are injected from the backward-side injection nozzles (D 1 and E 1 ) are alternatively shifted in the longitudinal direction of the blade rubber. Therefore, in wiping-out motion of the blade rubber for one reciprocation, the front glass ( 12 ) can uniformly get wet, the total number of injection nozzles can be made less than ever, the consumption amount of washer liquid (W) at the time of reciprocating wiping-out motion of the blade rubber can be reduced, power consumption of the washer pump can be reduced, and the size of the washer pump can be decreased.

First claim

What is claimed is:

1 . A wiper blade attached to a wiper arm provided to a vehicle to make reciprocating wiping-out motion over a windshield, the wiper blade comprising:
a blade rubber provided to the wiper blade and in contact with the windshield; and a washer apparatus provided to a coupling unit between the wiper arm and the wiper blade to inject washer liquid, wherein the washer apparatus has a plurality of forward-side injection nozzles oriented to a forward side of the blade rubber and a plurality of backward-side injection nozzles oriented to a backward side of the blade rubber, injection positions toward which washer liquids are injected from the forward-side injection nozzles and injection positions toward which washer liquids are injected from the backward-side injection nozzles are shifted in a longitudinal direction of the blade rubber and alternatively arranged in the longitudinal direction of the blade rubber, the injection positions toward which washer liquids are injected from the forward-side injection nozzles are close to one end of the blade rubber in the longitudinal direction and close to the other end of the blade rubber in the longitudinal direction as compared with the injection positions toward which washer liquids are injected from the backward-side injection nozzles.

2 . (canceled)

3 . The wiper blade according to claim 2 , wherein among the forward-side injection nozzles and the backward-side injection nozzles, nozzles disposed on both sides in the longitudinal direction of the blade rubber are respectively oriented to one side and another side in the longitudinal direction of the blade rubber.

4 . The wiper blade according to claim 1 , wherein the number of forward-side injection nozzles is larger than the number of backward-side injection nozzles.

5 . The wiper blade according to claim 1 , wherein,
a forward-side injection nozzle closest to one side in the longitudinal direction of the blade rubber among the forward-side injection nozzles is disposed closer to said one side in the longitudinal direction of the blade rubber as compared with a backward-side injection nozzle closest to said one side in the longitudinal direction of the blade rubber among the backward-side injection nozzles, and a forward-side injection nozzle closest to another side in the longitudinal direction of the blade rubber among the forward-side injection nozzles is disposed closer to the other side in the longitudinal direction of the blade rubber than a backward-side injection nozzle closest to the other side in the longitudinal direction of the blade rubber among the backward-side injection nozzles.

6 . A wiper blade attached to a wiper arm provided to a vehicle to make reciprocating wiping-out motion over a windshield, the wiper blade comprising:
a blade rubber in contact with the windshield; a holder member which holds the blade rubber and has elasticity; a vertebra provided inside the holder member, and adapted to bring the blade rubber into intimate contact with the windshield, a coupling member fixed to the vertebra, the coupling member having stiffness higher than stiffness of the holder member and coupled to the wiper arm; an attachment hole opening in a direction crossing a longitudinal direction of the blade rubber; and a washer apparatus having a fixing claw to be inserted and fixed to the attachment hole, the washer apparatus to be fixed to the coupling member.

7 . The wiper blade according to claim 6 , wherein the fixing claw includes: a positioning claw for positioning the washer apparatus with respect to the coupling member; and a retaining claw for preventing the washer apparatus from coming off from the coupling member.

8 . The wiper blade according to claim 6 , wherein a cover member is provided between the coupling member and the washer apparatus so as to cover the coupling member.

9 . The wiper blade according to claim 8 , wherein the washer apparatus is provided in a range of a projected area of the cover member in a planar view from a direction crossing the longitudinal direction of the blade rubber.

10 . A wiper blade attached to a wiper arm provided to a vehicle to make reciprocating wiping-out motion over a windshield, the wiper blade comprising:
a blade rubber including a contact unit in contact with the windshield; a holder member which holds the blade rubber; a vertebra provided inside the holder member, and adapted to bring the blade rubber into intimate contact with the windshield; a coupling member provided to the vertebra, and coupled to the wiper arm; and a washer apparatus fixed to the coupling member, and shorter in length than the holder member in the longitudinal direction the holder member, wherein the washer apparatus is at a position away from the windshield from a boundary part between the holder member and the blade rubber in a plane perpendicular to a longitudinal direction of the blade rubber.

11 . The wiper blade according to claim 10 , wherein in the plane perpendicular to the longitudinal direction of the blade rubber, the washer apparatus is disposed outside a region between a first reference line passing through the contact unit and in parallel with a front surface of the windshield and a second reference line passing through the contact unit and in contact with the holder member.

12 . The wiper blade according to claim 10 , wherein a cover member is provided to the coupling unit so as to cover the coupling unit, and the washer apparatus is provided in a range of a projected area of the cover member in a planar view from a direction crossing the longitudinal direction of the blade rubber.

13 . The wiper blade according to claim 10 , wherein the washer apparatus has a lower surface provided on the same side as the blade rubber, the lower surface extending substantially parallel with the windshield and having: an injection nozzle which injects washer liquid; and a tilted surface tilted upward from the lower surface as heading toward a side away from the blade rubber.
