A surface wiper device which includes a carrier which supports a blade. The carrier attaches to a wiper arm which urges the blade against and moves the blade across the surface of a windshield. The carrier further provides a plurality of outlets each of which communicate between a hollow passage inside the carrier and a location on the external surface of the carrier. A fluid can be delivered from a fluid source fluidicly coupled to the hollow passage of the carrier under sufficient pressure to be dispersed from the plurality of outlets onto the windshield during movement of the blade. A fluid heater can be thermally coupled with the fluid delivered from the fluid source to the plurality of outlets to increase the temperature of the fluid dispersed onto the windshield. The fluid can be sufficiently heated to generate a heated gas.

A wiper including wiper bracket which couples a wiper arm to blade carrier which carries one or more blades and includes an internal flow path which conducts fluid from a wiper bracket inlet through a hollow passage in a wiper blade carrier cover to plurality of outlets aligned with passthroughs in the blade carrier through which fluid egresses from the wiper.

The invention relates to a wiper frame (10), in particular for a motor vehicle, comprising a wiper blade (14), a liquid channel (30, 32) for carrying a cleaning liquid, and a heating unit (38). According to the invention, the heating unit (38) is substantially located inside the liquid channel (30, 32).

The present disclosure relates to a coating composition for a wiper blade comprising graphene and a wiper blade coated using the same. More particularly, the present disclosure relates to a coating composition for a wiper blade comprising graphene that may improve durability, an abrasion resistance, and a slip property of a wiper blade, a wiper blade coated using the coating composition, and a method for manufacturing the wiper blade.

The present invention relates to a device for cleaning at least one optical surface of a vehicle, including at least one rod which extends mainly along a longitudinal elongation axis. The rod including an element for spraying a cleaning fluid and a wiper blade configured to wipe the optical surface. The device further including at least one actuation means driven to move the rod in a first longitudinal direction of movement parallel to the longitudinal elongation axis, and in a second longitudinal direction of movement opposite to the first longitudinal direction of movement. The device additionally includes at least one means for limiting and/or compensating for at least one return force exerted on the rod.

The invention relates to a blade for a windshield wiper device and to a corresponding windshield wiper device. The blade comprises a blade body for wiping said windshield surface and a longitudinal rib. The body has a first housing extending longitudinally inside the body and having at least one insertion end. The rib has a cross-section complementary to the cross-section of the first housing. Furthermore, the rib comprises a plurality of interlocking members protruding from its surface by way of a harpoon with an interlocking end. The plurality of interlocking members is oriented such that they allow the insertion of the first end of the rib through the insertion end for assembling the blade, but prevent the extraction of the rib from the first housing.

A vehicle wiper blade comprises a blade support part and a lip part coupled swingably with the blade support part via a neck. The lip part comprises polyurethane. The polyurethane comprises a reactant of a composition including an isocyanate compound which includes diisocyanate and tri- or higher functional polyfunctional isocyanate, and an alcohol which includes tri- or higher functional polyfunctional alcohol. The diisocyanate has an aromatic ring in a molecule. When a molecule of the polyurethane is ionized with a mass spectrometer of a direct sample injection system, then obtained M1, M2 and M3 satisfy the following relation: M2/M1 is 0.001 to 0.028, M3/M1 is 0.020 to 0.110, and M2/M3 is 0.013 to 0.300, and a concentration of the polyfunctional alcohol in the polyurethane is 0.12 mmol/g to 0.65 mmol/g.

A vehicle windshield wiper blade comprising: a blade support portion; and a lip portion, wherein the lip portion has a tapered portion having a cross section that is taken along a direction perpendicular to the longitudinal direction of the wiper blade and that has a width that gradually decreases from a side closer to the blade support portion towards a direction farthest away from the blade support portion, the lip portion has a tip surface and first and second tapered surfaces constituting the tapered portion, and, in a specific observation region of the first and second tapered surfaces, the average value of the elastic modulus measured at a 0.1 μm pitch is 15-470 MPa and the coefficient of variation of the elastic modulus is at most 17.6%.

A motor vehicle wiper blade includes a spoiler which extends along a longitudinal direction and a lip disposed on the spoiler. The spoiler has, along the longitudinal direction, a cutout which extends in a direction of the lip. The motor vehicle wiper blade has an inner circle side and an outer circle side. The cutout is disposed on the inner circle side of the motor vehicle wiper blade and there is no cutout on the outer circle side of the motor vehicle wiper blade.
