Abstract

A wiper blade includes blade rubber, a holder body, and a clip. The clip is pivotally connected to the holder body. The clip has an elastic piece and an engagement protrusion. The engagement protrusion engages with an engagement hole provided in a wiper arm. The elastic piece section has a long piece section, a turned-back section, a first bending axis, and a second bending axis. The long piece section extends through a position to a side of the engagement protrusion. The turned-back section extends so as to change the direction of the long piece section in order to connect the front end of the long piece section to the engagement protrusion. The first bending axis and the second bending axis extend so that the engagement protrusion is located between the first bending axis and the second bending axis.

First claim

1 . A wiper blade coupled to a wiper arm, the wiper blade comprising:
a rubber blade that wipes a wiping surface; a holder body that holds the rubber blade; and a coupling member coupled to the holder body pivotally about an axis, wherein the axis extends in a widthwise direction of the rubber blade, and the coupling member includes an elastic piece and a locking projection, which is arranged in the coupling member and supported by the elastic piece, wherein: the locking projection is fitted into and engaged with a locking hole arranged in the wiper arm to couple the wiper blade to the wiper arm;
the elastic piece includes a long piece, a reversed portion, a first flexing portion, and a second flexing portion;
the long piece extends at a location beside the locking projection as viewed in a projecting direction of the locking projection;
the reversed portion extends to change a direction of the long piece and connect a distal end of the long piece to the locking projection; and
the first flexing portion and the second flexing portion extend so that the locking projection is located between the first flexing portion and the second flexing portion.

2 . The wiper blade according to claim 1 , wherein:
the elastic piece is one of two elastic pieces; and the two elastic pieces are arranged so that the locking projection is located between the two elastic pieces as viewed in the projecting direction of the locking projection.

3 . The wiper blade according to claim 1 , wherein the long piece extends in a direction that differs from an attachment-removal direction of the wiper arm.

4 . The wiper blade according to claim 3 , wherein:
the coupling member further includes a restriction portion; and the restriction portion restricts movement of at least one of the locking projection and the elastic piece in a removal direction of the wiper arm.

5 . The wiper blade according to claim 4 , wherein:
the coupling member includes an upper wall and side walls, which extend downward from two end portions in the widthwise direction of the upper wall; the locking projection and the elastic piece are formed on the same surface as at least either one of the upper wall and the side walls; a slit separates the locking projection from the elastic piece; and the restriction portion is a projection that projects into part of the slit.

6 . The wiper blade according to claim 4 , wherein:
the restriction portion is formed at a first location and a second location; the first location is a location in the coupling member corresponding to a distal portion of the long piece that includes the distal end of the long piece; and the second location is a location in the coupling member corresponding to a distal portion of the locking projection, wherein the distal portion of the locking projection is located at a side opposite to a basal end portion of the locking projection, and the basal portion of the locking projection is a portion of the locking projection where the reversed portion is connected.

7 . The wiper blade according to claim 4 , wherein:
the coupling member further includes an opposing portion that opposes the restriction portion; at least one of the restriction portion and the opposing portion includes an inclined surface; and the inclined surface is inclined to generate a component force in the projecting direction of the locking projection when at least one of the locking projection and the elastic piece receives force in the removal direction of the wiper arm.

8 . A wiper comprising:
the wiper blade according to claim 1 ; and the wiper arm.
