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.

The wiper lip is configured such that the rigidity of the wiper lip in the wiper direction (1) is greater than the rigidity of the wiper lip vertical to the wiping direction.

Provided is a wiper blade rubber which exhibits high adhesion to glass surfaces, excellent friction performance and excellent wiping performance, while being free from the occurrence of a bulge (blister) in a coating layer due to bleeding from a rubber substrate or blooming. A wiper blade rubber which has a lip part obtained by forming a coating layer on a rubber substrate by spray coating, and which is characterized in that: the coating layer is composed of a portion (A) that covers the rubber substrate and portions (B) that do not cover the rubber substrate; the portions (B) are a plurality of pores which are uniformly dispersed in the entire area of the coating layer and have diameters of 10 to 40 m; and the ratio of the total area of portion (A) that covers the rubber substrate to the total area of the portions (B) that do not cover the rubber substrate is from 40:60 to 60:40.

The present invention relates to a vehicle wiper blade having two or more edges, including: a pair of stopping parts coupled to a wiper body in such a manner as to be branched from the undersides thereof; bent parts disposed on the underside surfaces of the pair of stopping parts; and wiping parts disposed on the undersides of the bent parts to wipe a window glass surface of a vehicle, wherein the bent parts and the wiping parts are left and right symmetrical with each other around a center line of the blade, and each wiping part includes a wiping contact part disposed on the lower end thereof in such a manner as to come into contact with the window glass surface to wipe the window glass surface.

The invention relates to a windshield wiper device (50, 70) for a vehicle, in particular a motor vehicle. The windshield wiper device comprises a wiper blade (51, 71) with an elongated upper part (52, 72) which is designed to be at least partly flexible, an elongated lower part (53, 73) which is designed to be at least partly flexible, and multiple connection elements (18) for connecting the upper part (52, 72) and the lower part (53, 73). The connection elements (18) are mutually spaced along a longitudinal extension (8) of the wiper blade (51, 71), and the connection elements (18) are designed to allow the upper part (52, 72) and the lower part (53, 73) to move relative to each other with a movement component along a longitudinal extension (8) of the wiper blade (51, 71), a cross-section of the wiper blade (51, 71) perpendicular to the longitudinal extension (8) of the wiper blade being substantially trapezoidal.

In a cross-sectional structure of an existing blade rubber having a non-hollow cross-section, only elasticity of a material of the blade rubber is used for pressure to wipe a windshield. Therefore, it is difficult for the blade rubber to flexibly follow change of a surface shape of the windshield, and sufficient wiping performance is not obtainable. A blade rubber to be attached to a frame of a vehicle wiper and to wipe the windshield according to the present invention includes a wing portion extending in a lateral direction to fix the blade rubber to the frame, a neck portion perpendicularly coupled to the wing portion, a deformation portion elastically deformable and coupled to a lower side of the neck portion, and a contact portion provided on a side of the deformation portion opposite to a side provided with the neck portion, and configured to abut on the windshield. The deformation portion internally includes a cavity portion having a heart-shaped cross-section. The neck portion is coupled to an upper intersection of two curved portions surrounded by an outside of the deformation portion and the heart-shaped cavity. The contact portion is coupled to a lower intersection.

Disclosed is a one-touch slide assembly type wiper blade in which a rail spring is coupled to an upper part of a rubber blade, a base cover is formed, in the longitudinal direction thereof, at the center of the rubber blade including the rail spring, and right and left spoilers are respectively assembled at both right and left parts of the base cover, wherein one or more bracket-shaped grip parts are formed on the bottom surface of the base cover respectively at the front side and the rear side thereof, and then the base cover is slidingly assembled in a state in which bidirectional movement can be freely performed using grip parts, and the right and left positions of the base cover, which is slidingly assembled, are fixed by the right and left spoilers, which are respectively coupled to the both side parts of the base cover.
