WIPER BLADE

摘要

injection positions (A2, B2, and C2) toward which washer liquids (W) are injected from the forward-side injection nozzles (A1, B1, and C1) and injection positions (D2 and E2) which washer liquids (W) are injected from the backward-side injection nozzles (D1 and E1) 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.

主权项

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.
