There is provided a wiper arm rotatably connecting an arm body to an arm head and including a spring member provided between the arm head and the arm body, the thickness of which is decreased while its mechanical strength is sufficiently maintained. A gap section reaching a pivot shaft hole is provided in a head connection section of a retainer. A recess is provided on a pivot shaft section of an arm head. During the retainer rotates, a straight section of the coil spring moves from the gap section to the recess. When the retainer reaches its upright position, the straight section is disposed within the recess. The pivot shaft section includes a projection disposed within the gap section and in contact with the divided pieces, on the both sides of the gap section.

A wiper arm and a windscreen wiper system, wherein the wiper arm comprises a joint part and a lever part and a spring, wherein the parts form a common joint. The spring is embodied here as a torsion spring.

A wiper apparatus which removes foreign matters from a windshield by rotating by a pivot of a vehicle may include an arm piece connected to one end of an arm retainer to connect a wiper blade, and a coupling portion having a step portion formed to extend along a longitudinal direction so that an upper surface of the arm piece and an upper surface of the arm retainer form a same surface when coupled to correspond to a coupling hole formed in the arm retainer.

A vehicle wiper comprises a retainer that is formed in an elongated shape open at the lower side facing toward a windshield, and that is provided so as to be capable of swinging about a shaft axis of a pivot shaft that is swung to-and-fro; a first nozzle member that is housed inside the retainer, and that is capable of ejecting washer fluid from an ejection portion; and 1 a retainer cover member that closes off an opening of the retainer, and that is formed with a window through which the ejection portion of the first nozzle member is externally exposed.

A wiper apparatus which removes foreign matters from a windshield by rotating by a pivot of a vehicle may include an arm piece connected to one end of an arm retainer to connect a wiper blade, and a coupling portion having a step portion formed to extend along a longitudinal direction so that an upper surface of the arm piece and an upper surface of the arm retainer form a same surface when coupled to correspond to a coupling hole formed in the arm retainer.

The invention relates to a windshield wiper device (100) for a vehicle, comprising a wiper blade (2) having an elongated upper part (10) and an elongated lower part (12), which are configured to be flexible, at least in part. Furthermore, the device comprises a plurality of connecting elements (18) for connecting the upper part (10) and the lower part (12), which are spaced apart from each other along a longitudinal extension (8) of the wiper blade (2), and which are configured to allow a movement of the upper part (10) and the lower part relative to one another with a motion component along a longitudinal extension (8) of the wiper blade (2). The windshield wiper device (100) further comprises a fastening device. The fastening device comprises a wiper-blade-side fastening part (20) and a fastening element (50). The wiper-blade-side fastening part (20) and the fastening element (50) are configured in such a manner that, by means of rotation of the wiper-blade-side fastening part relative to the fastening element, an engagement can be formed in order to fix a position of the wiper-blade-side fastening part relative to the fastening element.

A mounting assembly for mounting a wiper blade to a wiper arm includes an adaptor adapted to be mounted to the wiper blade, the adaptor including a base wall and a plurality of side walls extending upwardly from the base wall, and a plurality of hinge pins extending outwardly from the side walls, and a coupler for connection to the wiper arm, the coupler including a base wall, a plurality of side walls depending from the base wall, and a plurality of openings extending into the side walls to receive the hinge pins to allow the coupler and the adaptor to be connected together.

An arm head includes a head-side engagement part with which a tension spring is engaged. An arm shank includes: a pair of sidewall parts disposed opposed to each other in a wiping direction; a top wall part provided on a side opposite to the wiping surface side of the pair of sidewall parts and connecting the sidewall parts to each other; a shank-side engagement part provided between the sidewall parts and with which the tension spring is engaged; and a spring accommodating recess provided at the top wall part and capable of accommodating a part of the tension spring. When the arm shank is raised, a part of the tension spring is accommodated in the spring accommodating recess, and when the arm shank is raised and viewed from a direction in which the sidewall parts are opposed to each other, the tension spring is hidden by the sidewall parts.

A wiper arm includes an arm head, a cover, and an arm body. The cover includes a top wall and a wall part. The top wall includes a fastening part extending toward the arm head side. The wall part includes a protruding part extending toward the arm head side. The arm body includes a connecting part that can be connected to the arm head. With the arm body and the arm head being connected by the connecting part, the arm head is covered by the cover. By one portion of the fastening part being engaged with the arm head, the other portion of the fastening part is brought into contact with the connecting part, and the protruding part is brought into contact with the arm head.
