A system and method are provided that enables windshield wiper blades to be replaced without the complexity of removing and reattaching adapters to the wiper arms with every wiper blade replacement cycle. The wiper blade adapter is reusable and stays connected to the windshield wiper arm while providing a simple connecting system that enables the attachment of the wiper blade to the base of the adapters. The adapters are made of engineered plastic that does not wear as quickly as the rubber squeegee and does not need to be replaced as often as the wiper blade. The reusable wiper blade adapter employs a simple mating connector on the wiper blade that provides for an intuitive motion to attach and detach from the base of the adapter thus providing for a simpler blade replacement process.

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 connecting structure of a wiper arm includes a connecting shaft provided on a wiper arm and a snap-fit provided on a wiper blade. The snap-fit includes a pair of claws defining a groove that can be engaged with the connecting shaft. A slit defined by inner walls facing each other is provided on both sides of the pair of claws in a longitudinal direction of the wiper blade. A first protrusion protruding toward inside of the slit is provided on one of the inner walls, and a second protrusion protruding toward inside of the slit is provided on the other of the inner walls. The first and second protrusions are arranged offset from each other in a direction along an axial direction of the connecting shaft.

The connection device (2) for connecting a wiper blade (3) of an optical surface (S) of a vehicle (V) to a drive arm (5) of the vehicle (V) comprises a circuit for channeling a liquid and comprising an inlet cannula (17) connected to a first duct (19a) and to a second duct (19b) both extending in a longitudinal direction of extension (AL) of the connection device (2). The first duct (19a) is capable of being in communication with the second duct (19b).

The disclosure relates to a wiper assembling structure, which includes a fixing seat, an accessory seat, and a blade set. The fixing seat includes a shell seat and multiple pressing blocks disposed in the shell seat. The accessory seat includes a bottom plate and two side plates perpendicularly extended from the bottom plate. Each of two ends of each side plate is formed with multiple protrusive sheets. The accessory seat is positioned in the fixing seat by inserting the protrusive sheets into the shell seat to be pressed by the pressing blocks. The blade set includes an elastic sheet and a rubber strip. The elastic sheet is disposed under the bottom plate. The rubber strip is connected with the elastic sheet and extended on one side of the accessory seat.

The present invention relates to a connector (1) for a wiper blade, designed to be interposed between an adapter and a structural element of the wiper blade. The connector (1) extends longitudinally between a first longitudinal end (14) and a second longitudinal end (14). The connector (1) comprises at least one fixing block (22) configured such as mechanically to connect the connector (1) to the structural element of the wiper blade and a linking block (13) configured such as mechanically to connect the connector (1) to the adapter. The connector (1) comprises at least one skirt (23) that extends longitudinally from the fixing block (22). The skirt (23) comprises at least one rib (24) that extends between the fixing block (22) and one of the longitudinal ends (14).

A wiper arm for use with a wiper blade, which is mechanically and detachably connectable to the wiper arm and to a wiper arm adapter by joining in an assembly direction using a wiper blade adapter, includes an electrical connecting element, disposed on a wiper arm side of the wiper blade adapter, configured to reversibly establish a connection to a second electrical connecting element on a wiper blade side of the wiper blade adapter. The connection between the electrical connecting element and the second electrical connecting element is formed along the assembly direction. The electrical connecting element and the second electrical connecting element are mounted floating. The electrical connecting element and the second electrical connecting element are mounted deflectable in a spatial plane oriented crossways to the assembly direction.

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.
