Abstract:
1. A wiper blade, comprising: a wiper rubber; and a lever assembly holding the wiper rubber and coupled to a wiper arm, the lever assembly including a plurality of levers, adjacent levers of which are hinge-jointed to each other, wherein one of the adjacent levers includes a spoiler portion forming a section of a spoiler integrated in the one of the adjacent levers and the other of the adjacent levers includes a spoiler portion forming a section of a spoiler integrated in the other of the adjacent levers, wherein the one of the adjacent levers includes an arm extending from the spoiler portion of the one of the adjacent levers toward the other of the adjacent levers and holding the wiper rubber at a distal end, wherein the arm of the one of the adjacent levers is situated in the spoiler portion of the other of the adjacent levers and is hinge-jointed to the spoiler portion of the other of the adjacent levers, wherein the one of the adjacent levers has a stepped surface which is inclined toward a distal end of the wiper rubber at a longitudinal inner end of the spoiler portion of the one of the adjacent levers, wherein the other of the adjacent levers has a stepped surface which is inclined toward a center of the other of the adjacent levers at a longitudinal outer end of the spoiler portion of the other of the adjacent levers, wherein the other of the adjacent levers includes a joint portion extending from the longitudinal outer end of the spoiler portion of the other of the adjacent levers toward the one of the adjacent levers and hinge-jointed to the arm of the one of the adjacent levers, wherein the lever assembly further includes a joint cover coupled to the joint portion between the one of the adjacent levers and the other of the adjacent levers, wherein the joint cover has a cross-sectional profile corresponding to a cross-sectional profile of the spoiler portion of the one of the adjacent levers and a cross-sectional profile of the spoiler portion of the other of the adjacent levers, and wherein the joint cover has a longitudinal outer end contacting the stepped surface of the one of the adjacent levers and a longitudinal inner end contacting the stepped surface of the other of the adjacent levers.
