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 fastening part (20) on the wiper-blade side, and a fastening element (50). The fastening part (20) on the wiper-blade side, and the fastening element (50) are configured such that by means of a rotation of the fastening part (20) on the wiper-blade side relative to the fastening element (50), an engagement can be formed in order to connect the fastening part (20) on the wiper-blade side to the fastening element (50), wherein the connection can be released by means of a release mechanism.

A windshield cleaning assembly for a vehicle includes a wiper that is operationally coupled to a wiper motor of a vehicle. A pipe is coupled to the wiper and extends from proximate to opposing ends of a blade of the wiper. The pipe has a first end that is closed. A pump is coupled to the vehicle is operationally coupled to an electrical circuit of the vehicle. A tank is coupled to the vehicle and is fluidically coupled to the pump. The tank is configured to position a fluid. A tube is fluidically coupled to and extends between the pump and a second end of the pipe. The pump is positioned to selectively pump the fluid from the tank through the tube and the pipe. The fluid exits the pipe under pressure through a plurality of holes to clean the windshield.

A variable curvature wiper comprises a wiper arm with a first and second distal ends. The first distal end is pivotally supported on a pivot post. A flexible wiper blade has a first end, a second end and a mounting hub. The mounting hub is pivotally attached to the second distal end of the wiper arm. A first push rod includes a first end attached to the first end of the wiper blade and a second end attached to a push rod pivot point. The push rod pivot point is spaced from the pivot post axis. Pivotal motion of the wiper arm about the pivot post axis in a first direction causes the first push rod to push against the first end and flex the wiper blade. Pivotal motion of the wiper arm about the pivot post axis in a second direction causes the first push rod to pull the first end of the wiper blade back toward a flat position.

A wiper device is disclosed. The wiper device of the present invention is coupled to a wiper arm and removes a foreign substance attached to a windshield. The wiper device includes a contact member configured to wipe off the foreign substance, a lever structure configured to press the contact member to be tightly in contact with the windshield and having a plurality of levers connected in a multi-level structure, and an adapter configured to be coupled to the lever structure and connected to the wiper arm, wherein the lever structure comprises a connection member configured to hinge-connect at least at least one pair of the plurality of levers.

A wiper device is disclosed. The wiper device coupled to a wiper arm to remove a foreign substance of the present invention includes a contact member configured to wipe off the foreign substance; a lever structure configured to press the contact member to be in contact with a windshield and having a plurality of levers connected in a multi-level structure from the wiper arm to the contact member; and an adapter configured to be coupled to the lever structure and connected to the wiper arm, wherein at least one lever of the plurality of levers is formed to have less width or equal width to that of a lower lever, based on the multi-level structure.

The invention relates to a method for reducing material creep processes of a windshield washer device. The method comprises the providing (201) of a windshield washer device for a vehicle. The windshield washer device comprises a wiper blade (2) having an elongated top part (10) and an elongated bottom part (12), which are designed to be at least partially bendable. Furthermore, there is a plurality of connecting elements (18) for connecting the top part and the bottom part, wherein the connecting elements are spaced apart from each other along a longitudinal extension (8) of the wiper blade. The connecting elements (18) are designed to enable a movement of the top part (10) and the bottom part (12) relative to each other, having a movement component along a longitudinal extension (8) of the wiper blade. The method further comprises a loading (202) of the windshield wiper device before final assembly of the windshield wiper device on a vehicle such that, after final assembly of the windshield wiper device, a primary creep behavior of the windshield wiper device is substantially reduced, in particular by at least 80%.

A wiper blade is presented having a wiper strip, a force distribution structure having opposite ends, the wiper strip connected to the force distribution structure, and a cover, wherein the cover is made from a hydrophobic material, a material exhibiting hydrophobic properties, or a material having a water contact angle that is greater than 90 degrees.

A windscreen wiper device for cleaning a windshield of a vehicle is provided. The windscreen wiper device includes a wiper strip for sealing against the windshield and at least one carrier element engaged with the wiper strip to bias the wiper strip into a predetermined configuration. A frame structure is coupled to the at least one carrier element and includes at least two components.
