Abstract: 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.

Abstract: A wiper blade including multiple frame components hingedly connected to one another and at least two joint springs applying elastic force to respective frame components, the wiper blade accommodating a changing curvature of a surface of a windshield.

Abstract: The invention discloses a wiper bracket and a wiper. The wiper bracket comprises a main bracket, at least one first sub-bracket and a connecting device. The connecting device contains a baffle located at the bottom of the first sub-bracket and the main bracket, with one end fixed at the main bracket or the first sub-bracket, and the other end being a free end. The free end is located on the bracket opposite to the fixed end of the baffle. A side of the first sub-bracket is pivotally connected to the main bracket by a pivotal shaft. A spring is disposed between the main bracket and the first sub-bracket, and located at an upper portion of the baffle. The compression resilience of the spring applies downwardly curved preload to the first sub-bracket.

Abstract: A spline for use in a windshield wiper assembly including a wiping element is provided. The spline is composed of a pair of elongate strips, and each strip includes a first curved portion having at least one pointed protrusion to penetrate the wiping element, a notched portion having a notch, a second curved portion provided at a side of the elongate strip, and a body portion to seat within the wiping element. An overall shape of the spline is convex or concave with a bottom surface of the spline directed toward a wiping lip of the wiping element.

Abstract: A wiper blade assembly including: a primary lever including a spoiler portion; and a secondary lever disposed on a side of the primary lever and hinge-coupled to the spoiler portion of the primary lever, wherein support portions are disposed on an inner surface of the spoiler portion of the primary lever and prevent the movement of the secondary lever. The support portions support the secondary lever to prevent the secondary lever from moving on the inner surface of the spoiler portion of the primary lever when a wiper is or is not in operation.

Abstract: A wiper blade includes a main lever, a movable member, and a rubber blade. The main lever can be coupled to a wiper arm. The main lever includes a longitudinally intermediate portion, a first end defined by at least one of two longitudinal ends, and a first holding portion. The first holding portion is arranged closer to the first end than the longitudinally intermediate portion. The movable member is pivotally coupled to the first end and includes a second holding portion. A rubber blade is held by the first holding portion and the second holding portion. A coupling portion between the main lever and the movable member is located outward from the first holding portion in the longitudinal direction of the main lever.

Abstract: A releasable squeegee assembly for coupling to a surface maintenance machine and including a compliant bushing and an over-center lever attached to a pull rod and compliant spring. The compliant bushing is compressed via said over-center lever with said compliant spring providing a spring force. A bushing sleeve is provided to limit the degree of compression of said compliant bushing by the over-center lever. A method of coupling a squeegee assembly to a surface maintenance machine is also provided.

Abstract: The present invention provides a wiping blade (30) for removing water from a surface having one or more vertebrae (32, 34, 36, 38) comprising at least one rail (32, 34) and at least one spring (36, 38), wherein said rail (32, 34) is curved and provides an elastic force quasi perpendicular to the windscreen, and said wire spring (36, 38) is fitted to said rail over its entire length or a part thereof and provides an elastic force in the direction of the length of the vertebra.

Abstract: A holder piece assembly having holder pieces continuously arranged and leaf spring members connecting between each holder piece, and being curved in the longitudinal direction by elastic force of elastic members is provided. The holder piece assembly is mounted on the front edge of a wiper arm through a clip pin. Blade rubber for wiping window glass surface is mounted on the holder piece assembly. The elastic force of the leaf spring members elastically deformed when the blade rubber is allowed to conform with the window glass surface can disperse the pressing force of the wiper arm over the blade rubber longitudinal direction. The dispersed pressing force can be set by changing the connecting angle between each holder piece according to the window glass curvature thereby the wiper blade versatility is improved.

Abstract: A wiper blade for cleaning windows, especially of motor vehicles, is proposed, which has an elongated, rubber-elastic wiper strip (20) that can be pressed against the window (22) and is retained by a multi-member support bracket system (12) that has a main bracket (14), located in the middle portion of the support bracket system, is provided with a bolt (26), oriented transversely to the length of the wiper blade (10), for pivotable connection to a wiper arm (28) that is urged toward the window and is driven to swing, resulting in one wiper blade half near the swing axis and one wiper blade half remote from the swing axis, and the wiper blade is provided with spring means, which under tension, when the wiper blade is pressed against the window, additionally urge the half remote from the swing axis toward the window.
