A contaminant removal apparatus for windshields includes: driving belts located at both side surfaces of a windshield; a drive unit configured to apply driving force to the driving belts; a wiper assembly located on the windshield; rotary rollers configured to be shifted along the driving belts; idle gears located at ends of the driving belts to change a rotating direction of the rotary rollers; frame connection shafts coupled to both ends of the wiper assembly and located within the rotary rollers so as to contact the idle gears to change the rotating direction of the rotary rollers; and a controller configured to change a rotating direction of the rotary rollers when the idle gears and the frame connection shafts contact.

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.

A windshield wiper scrubbing device for cleaning a windshield is disclosed. The windshield wiper scrubbing device comprises an arm comprising a top side and a bottom side. The arm moves in a first and second vertical direction. The bottom side of the arm comprises a scrubbing rod that moves in a first and second horizontal direction. A liquid canister releases cleaning solution onto the windshield upon a first actuation of a switch. A scrubbing pad located on the scrubbing rod is placed onto the windshield through a first rotation in a first rotational direction after the windshield receives the cleaning solution. A scraper located on the bottom side of the arm is placed onto the windshield through a second rotation in a second rotational direction upon a second actuation of the switch. A motor powers the scrubbing rod and rotates in the first rotational direction and the second rotational direction.

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 device for converting a rotational motion into a reciprocating angular motion and a wiper system including the same include a fixed body fixed to a certain object; a rotating body rotatably connected to the fixed body and rotating around a fixed axis; and a torsion spring coupled to the fixed axis and having an end portion and an opposite end portion, the end portion being held by the fixed body and the opposite end portion being held by the rotating body.

The present invention is a windshield wiper with jet ejectors for use in vehicles. Each windshield wiper with jet ejectors includes a movable arm that oscillates a frame. Frame is provided with and oscillates along with at least one flexible element and a jet ejector. Cleaning fluid tube is connected to jet ejector and supplies cleaning fluid to jet ejector. Oscillation of frame causes distribution of cleaning fluid in jet ejector. Jet ejector has a number of openings though which distributed cleaning fluid is ejected out on windshield of vehicle. Simultaneous action of ejection of cleaning fluid and oscillation of flexible element(s) provide cleaning of windshield along the entire length of frame. Thus, conventional partial cleaning of windshield due to inappropriate distribution of cleaning fluid is eliminated by distributing fluid along the entire length of windshield wiper. Appropriate and fast cleaning of windshield increases visibility improvement for the driver.

This invention relates to tape of glass cleaning brushes, mainly to automobile windscreen wipers, and can be used universally for efficient cleaning of the windscreen of a motor vehicle in any weather conditions.

The windscreen cleaning brush tape is made of an elastomeric material that can be firmly, without any gaps and installed motionless in the holder, while an axisymmetric cavity, triangular in its cross-section, runs along the entire length of the tape through the body of the scraper above its stretched out portion, and the sides of the triangular cavity run parallel to the sides of the scraper, forming sidewalls of the scraper. In another claim of this invention, the base of the triangular cavity carries at least one longitudinal symmetric rib, the vertex of which is directed towards the contacting portion of the scraper. Geometry and quantity of longitudinal ribs inside the cavity may vary. Also, the cleaning edge carries an axisymmetric longitudinal notch of triangular cross-section, which forms two symmetrically protruding wedge-shaped edges, running along both longitudinal sides of the stretched out contacting portion of the scraper.

Higher efficiency of windscreen wipers motor vehicles at sub-zero temperatures is achieved. The offered tape for wipers is simple in structure and production method and is easy to use.
