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.

A wiper unit for an automobile windshield wiper system has at least one wiper arm connectable to a wiper drive of the windshield wiper system and at least one wiper blade supported by the wiper arm. In order to provide a lightweight wiper unit that can be produced cost-effectively and offers greater design freedom, at least one fiber-reinforced nonmetallic strip is arranged on the outside of the wiper arm and/or the wiper blade. That nonmetallic strip extends over at least half the length of the wiper arm or wiper blade, is connected to the wiper arm or the wiper blade in a substance-bonded manner, and is arranged at least in part on a side of the wiper arm or wiper blade which is arranged facing or facing away from an automobile windshield which is to be wiped.

Provided is a windshield wiper frame, including a main frame and two auxiliary frames, wherein the main frame is in the shape of an arch, and the main frame is of an elastic structure; and middle parts of the two auxiliary frames are movably connected to end parts at two ends of the main frame, respectively. When in use, a wiper arm is movably connected to a middle part of the main frame, and a wiper blade is fixed to the auxiliary frames. The windshield wiper frame is beneficial for guaranteeing a wiping effect of the wiper blade.

A windscreen wiper device for cleaning a windshield of a vehicle is provided. The windscreen wiper device includes a wiper strip for sealing against the windshield and at least one carrier element engaged with the wiper strip to bias the wiper strip into a predetermined configuration. A frame structure is coupled to the at least one carrier element and includes at least two components. One of the components presents an elongated member with a resilient tab, and another component includes a longitudinally extending opening. One of the walls of the opening has a recess shaped similarly to the resilient tab. The elongated member is inserted into the opening until the resilient tab snaps into the opening to interconnect the components.
