A coating composition for imparting a hydrophobic film on a target surface is provided that includes an oil of a silicone oil or a fluoropolymer oil or a combination thereof, a resin, and a dry lubricant. A solvent is present to form a solution of the oil and resin. A coating is imparted to an applicator that in turn can transfer the coating as a hydrophobic film. The coating composition is stable and able to impart hydrophobic film even after storage for several weeks at elevated temperature. The coating composition does so through the exclusion of synthetic waxes especially including silicone waxes. A kit is also provided that includes a wiper blade having the above coating composition applied along with instructions for the securement of the wiper blade to a vehicle to impart the hydrophobic film to a vehicle windshield contacted by the wiper blade.

The invention relates to a wiping rubber for wiper blades in windshield wipers, comprising a profile body formed of an elastomer or rubber material, at least partially having a surface coating. The surface coating (22) comprises carbon fibers (24).

A formulation for the preparation of a wiping blade element for a vehicle windscreen wiper blade is disclosed. The formulation has an elastomer material based on chloroprene rubber in which plasticizing additives are incorporated, where the plasticizing additives include a combination of at least a first additive, the pour point of which is less than 50 C., and at least a second additive, the pour point of which is greater than 50 C. The first additive is octyl sebacate in a proportion of 4 phr and the second is a naphthalic oil plasticizer or a C.sub.18-C.sub.30 tricarboxylic ester in a proportion of 10 phr.

A window wiper includes an elongated profile of waterproof flexible material having a base extending under weather stripping for a side vehicle window, a support connected along the base to extend above the weather stripping, a cover connected along the support and extending over the base for covering at least some of the weather stripping and a wiper portion connected along the support and having a resilient wiper area for pressing against the window. A length of adhesive tape is connected along the profile and extends over the base for adhering to the weather stripping to fix the window wiper to the weather stripping.

A vehicle wiper assembly includes a wiper blade having a length, and an active material disposed along the length of the wiper blade and coupled thereto. The active material includes a shape memory alloy material with a crystallographic phase that is changeable between austenite and martensite, and is elastically deformable and operatively applies a spring force against a portion of the wiper blade when the crystallographic phase is martensite.

The invention relates to a wiper blade (10) of flat bar design composed of a wiper strip (14) comprising a wiper lip (18) connected to a head strip (22) via a tilting web (20), at least one pre-bent, elastic spring rail (46, 52, 54) acting as a supporting element, a connecting element (12) and a spoiler (32) having a flowing profile (34) and a holding profile (38), wherein the spoiler (32) includes in the flowing profile (34) thereof at least one longitudinal channel (44, 48, 50) with a spring rail (46, 52, 54), and the holding profile (38) thereof has at the longitudinal sides thereof free branches (42) opposite each other, directed inward, engaging into respective longitudinal grooves (24) of the head strip (22). According to the invention, the head strip (22) is free of spring rails, and in particular no spring rail (46, 52, 54) will contact the head strip (22).

The present invention relates to a method for producing a wiper blade element (10) for a wiper blade and/or a wiper blade having a wiper blade element (10), in particular for a windscreen wiper. In order to provide simple and economical wiper blade elements and wiper blades having excellent properties, in particular having high wiping quality, high abrasion resistance, a high degree of friction reduction and miming noise reduction and a long service life, in said method a particle layer (12) is applied to an elastomer substrate (11), the elastomer substrate (11) is vulcanised with the particle layer (12) deposited thereon, and, after vulcanisation, a friction-reducing material (13) is applied to the particle layer (12). The invention further relates to a wiper blade element and wiper blade produced in such a way.

This blade rubber has a high level of an ability to follow various shapes of surfaces to be wiped and excellent wiping performance. In a blade rubber that is made of an elastic member containing polyurethane and cleans the surface of a member to be cleaned by bringing a part of the elastic member into contact with the surface of the member to be cleaned, when the storage elastic modulus of the blade rubber at a vibration frequency of 110.sup.3 Hz in an environment of 8 C. is E(1), and the storage elastic modulus at a vibration frequency of 110.sup.4 Hz is E(2), E(1) is 12.0 to 18.0 MPa, and E(2) is 530 to 1500 MPa.

A wiper assembly may include a wiper blade comprising: a blade element; and a support element secured to the blade element along a blade element length of the blade element. A wiper assembly may include a flat spring coupled on a first end to a first end of the support element via a first coupling and coupled on a second end to a second end of the support element via a second coupling. A wiper assembly may include a saddle clip disposed between the first end of the support element and the second end of the support element and configured to couple the flat spring to the support element, wherein a downward biasing of the saddle clip causes the wiper assembly to bias against the windshield.
