Described is a wiper blade for a windshield of a vehicle. The wiper blade having a frame structure, a squeegee, and a plurality of debossed features. The squeegee is coupled to the frame structure and includes a wiping lip. The plurality of debossed features is formed in a side wall of the wiping lip. The plurality of debossed features extend along a length of the wiping lip. Each of the plurality of debossed features can also include treatment compound.

A coating agent for a wiper blade rubber having superior friction performance and wiping performance, both initially and during use for an extended period, and having superior durability by inhibiting wear and the like, and a wiper blade rubber using the same. The coating agent for the wiper blade rubber includes a solid lubricant and a binder containing a polycarbonate-based polyurethane resin. The wiper blade rubber has the coating agent on both lateral surfaces of a lip portion of the wiper blade rubber.

[Means for solving problem] The resin composition of the present invention comprises 100 parts by mass of a specific ethylene/-olefin/non-conjugated polyene copolymer (A) and 0.1 to 5 parts by mass of a peroxide (B), and the copolymer (A) comprises structural units derived from ethylene (a1), an -olefin (a2) having 3 to 20 carbon atoms, and a non-conjugated polyene (a3) including intramolecularly two or more partial structures in total selected from the group consisting of structures represented by the following formulae (I) and (II),

[Effect] The resin composition of the present invention is excellent in crosslinking properties and the resin composition and its crosslinked shaped article of the present invention can be used, without any limitation, in various applications known as applications of rubber composition, and can be suitably used, for example, for interior and exterior parts for automobiles and applications requiring heat resistance.

A wiper blade is provided that includes a blade having an outer surface and terminating in a lip tip. A permanent silicone outer coating derived from a liquid silicone rubber is bonded to at least to the lip tip. The coating can also encapsulate the blade. An improved process for operating a wiper blade is also provided in which the wiper blade has a blade with an outer surface and terminating in a lip tip. The improvement involves curing a liquid silicone rubber to adhere a permanent silicone outer coating at least to said lip tip and then movably contacting said lip tip with a windshield.

A method for manufacturing an elongated windshield wiper blade includes providing a tandem wiper blade (1) made in one piece of an elastomeric material, which is composed of two wiper blades (2, 3) integrally joined together, and subsequently cutting the tandem wiper blade (1) so as to separate the two wiper blades (2, 3) each having a wiping head (4) facing away from a windshield to be wiped and a wiping lip (5) to be placed in abutment with a windshield to be wiped. The two wiper blades (2, 3) forming the tandem wiper blade (1) are integrally joined together at the location of their wiping heads (4) facing towards each other, wherein the tandem wiper blade (1) is cut into the two separate wiper blades (2, 3) along their wiping heads (4) facing towards each other.

A wiper device for a windshield, the device including a wiper arm, and a wiper blade mounted on the wiper arm, wherein the wiper blade includes a blade rubber and a blade stay which supports the blade rubber, the blade rubber includes: a base which is a part of the blade rubber to be mounted on the blade stay; a lip; and a neck which swingably connects the lip to the base, wherein at least a portion of the tip of the lip constitutes a contact part with a windshield, abuts the wiper arm to a glass flat plate and moves the glass flat plate, and in a stop state, the width of the contact part of the blade rubber and the glass flat plate is 1.0 20.0 m, and an angle between a specific position of the lip and the glass flat plate is 20 to 80.

The invention relates to a wiping member (10) comprising an elastomer-based material, a coating being provided on at least part of an external surface of the material. At least part of the surface of the assembly formed by the elastomer-based material and the coating has an increased degree of cross-linking over at least one surface thickness of the assembly. The invention also relates to a windshield wiper blade and to a method for treating a wiping member.

The present invention relates to a wiper rubber (10) for a windshield wiper, comprising a wiper rubber substructure (1) with a wiper lip section (2) and a reinforcement section (4), the wiper rubber substructure (1) being uncoated and being formed from ethylene-propylene-diene rubber and/or ethylene-propylene rubber. In order to improve the wear resistance, wiping characteristics and wiping quality of the wiper rubber (10), the surface of the wiper rubber substructure (1) at least in a partial region (2c, 2c) of the wiper lip section (2) has been treated with ultraviolet radiation. The present invention further relates to a process for producing a wiper rubber, to a correspondingly produced wiper rubber and to a windshield wiper equipped therewith.

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 blade rubber has an elongate shape extending along a longitudinal direction. The blade rubber includes a basal portion retained by a rubber holder and a wiping portion extending downward from the basal portion. The wiping portion slidably contacts and wipes a wiped surface along a width direction. The wiping portion has a cross-sectional shape, which inclines with respect to a downward hanging direction when the blade rubber is in an unloaded state. The cross-sectional shape is a shape of a cross-sectional surface of the wiping portion. The cross-sectional surface extends along a direction perpendicular to the longitudinal direction. The downward hanging direction is a direction, which extends along a direction perpendicular to the longitudinal direction and the width direction.
