A wiper blade may include a central connection device having an upper passage and a lower passage. An upper beam may be provided in the upper passage and a lower beam may be provided in the lower passage. The lower beam may also support a wiper strip. In use, the upper beam may forcibly contact the lower beam. A cover may be provided, and the cover may have an airfoil cross-sectional profile. A wiper blade assembly is also disclosed utilizing an embodiment of a wiper blade with a connector for connecting the wiper blade with a wiper arm of a vehicle.

A wiper blade wipes a wiping surface. The wiper blade includes a blade rubber that is disposed in contact with the wiping surface, a wiper case that holds the blade rubber, and a state changing member that is accommodated in the wiper case and rotatable in the wiper case. The state changing member is rotatable in the wiper case or movable in a longitudinal direction. The state changing member is configured to change a curved form or rigidity in the longitudinal direction of the wiper blade in accordance with a curved form of the wiping surface when a rotational position or a longitudinal position of the state changing member is changed.

An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a first end of the wiper arm, and an output shaft coupled to a second end of the wiper arm. The wiper blade includes a support member coupled to a blade element through a clip and a fastener extending through the blade element. The support member can be made from a composite material and the clip and fastener allow for attachment of the blade element to the support member without piercing the support member.

A wiper blade having a wiper strip having a wide portion and a lip, and an elongate backing element. The backing element having a top portion, and two opposing legs that descend from the top portion, such that each opposing leg has a claw which extends towards the other opposing leg. A gap formed between the claws that is narrower than a width of the wide portion of the wiper strip. The claws, legs, and top portion define a wiper strip cavity sized to receive the wide portion wiper strip.

A wiper structure for a resin window includes a wiper configured to wipe a part of a surface of the resin window. The wiper has an elastic wiper rubber and a wiper holder configured to hold the wiper rubber. The wiper rubber has a holding base portion, a lip portion, a body portion, and a neck portion. The lip portion is in contact with the resin window. In the lip portion, a ratio of a lip length in the direction toward the surface of the resin window to a lip thickness in the thickness direction is greater than 0 and less than or equal to 2.3.

A wiper blade including an elongate wiper strip, an elastic backing element and a mounting base. The wiper strip including a lip, a wide portion, and narrower intermediate portion between the lip and the wide portion. The backing element having a top portion from which two legs descend, such that each leg includes a claw that extends towards the opposite leg and has ends that define a gap sized to receive the intermediate portion of the wiper strip. The top portion, legs and claws of defining a wiper strip cavity where the wide portion of the wiper strip is disposed. The mounting base disposed on a section of the backing element and capable of connecting the wiper blade to a wiper arm and receiving force from same, such that the mounting base applies the force from the wiper arm to the backing element, which distributes same along the wiper strip.

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.
