The present invention relates to a coating composition for a wiper blade and a method for coating a wiper blade using the same. More particularly, the present invention relates to a coating composition for a wiper blade and a coating method using the same, which can improve the durability of the wiper blade and prevent discoloration of the wiper blade.

A wiper system for vehicles is provided. The system includes a heated wiper blade assembly, a heated cowl assembly and a controller. The controller receives input from one or more sensors or systems and causes a power source to provide, reduce or stop power to heating elements in the blade and/or cowl depending upon sensed conditions. At least some components in the assembly comprise thermally conductive polymers. The system provides surprisingly advantageous results in that it is effective for melting and clearing ice and snow with a lower than expected pull on a power source such as a battery.

A windscreen wiper device is provided including a longitudinally extending wiper strip of a flexible material. At least one carrier of a spring-like material operatively supports and biases the wiper strip into a predetermined configuration. The windscreen wiper device further includes a connecting device for connection with a wiper arm. At least a portion of the wiper strip has a microtextured surface formed directly into the flexible material. The microtextured surface may be on, for example, any one of or any combination of a wiping portion, a channel, a hinge portion and a spoiler portion of the wiper strip.

Disclosed is a block copolymer including one or more blocks of an acrylate polymer and one or more blocks of a chloroprene polymer, wherein the number average molecular weight of the block copolymer is 110,000 or more, the number average molecular weight of the block of a chloroprene polymer is 80,000 or more in total, and the block copolymer has a functional group with a structure represented by the following chemical formula (1) or (2):

##STR00001##

wherein in the chemical formula (1), R.sup.1 represents hydrogen, chlorine, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aryl group or a substituted, or unsubstituted heterocyclyl group.

A wiper rubber (10) for a wiper blade, especially for a windshield wiper, with an elastomer material comprising a polymer blend composed of at least one ethylene-propylene-diene rubber and/or at least one ethylene-propylene rubber, and at least one ethylene-vinyl acetate copolymer is disclosed. In order to provide a wiper rubber that has improved wiping quality and improved running properties, especially reduced or zero running noise, such as humming, whistling, squeaking, smacking, turnover noises, et cetera, both at moderate and especially at cold outside temperature, and especially also over a broad frequency range customary in wiper operation, the at least one ethylene-vinyl acetate copolymer, based on the total weight of the at least one ethylene-vinyl acetate copolymer, comprises a vinyl acetate content within a range from 40% by weight to 90% by weight, where the polymer blend, based on the total weight of the polymers in the polymer blend, comprises 0.1% by weight to 30% by weight of the at least one ethylene-vinyl acetate copolymer.

A vehicle wiper control apparatus monitors whether warpage occurs in a wiper strip made of a rubber-elastic material that is provided in a wiper blade. When a wiper of a vehicle is turned off and the warpage occurs in the wiper strip, the control apparatus controls the wiper mechanism to move the wiper blade to a parking position thereby preventing deformation of the wiper strip and maintaining the performance thereof.

A windshield wiper system (WWS) blade assembly is provided. The WWS blade assembly includes a composite frame and a blade that has a length which is normally shorter than a corresponding length of the composite frame. The blade includes first and second ends attachable to corresponding first and second ends of the composite frame, respectively.

The present invention provides a wiper blade, by balacing the opposite characteristics between the ease of operation and the cleaning force, the overall shape of the wiper blade is inclined laterally with elasticity in accordance with the moving direction of the blade mounting means for ease of operation, and the contact portion of the wiper blade for performing the cleaning is capable of maintaining an angle close to a right angle with respect to the cleaning surface, so that the wiper blade is also excellent in cleaning force.

This disclosure relates to a coating composition for a silicone wiper blade and a rubber wiper blade using the same. More particularly, this disclosure relates to a coating composition for a silicone rubber wiper blade which has excellent wiping durability and water-repellent properties, and a silicone rubber wiper blade which does not require a chlorine surface treatment process using the coating composition for a silicone rubber wiper blade.
