The invention is based on a wiper blade adapter, in particular for a motor vehicle wiper device, with a coupling unit (10a; 10b). It is proposed that the coupling unit (10a; 10b) has at least one first and one second coupling element (12a, 14a; 12b, 14b), which coupling elements are provided for coupling at least two different types of wiper arm adapters (100a, 110a, 120a; 130b, 140b).

A kit for connecting a wiper blade and multiple types of wiper arms, the kit including a container and a set of connectors located within an interior of the container. The set of connectors includes a first connector having a structure to receive and be connected to at least two different wiper arms that are part of a first class of wiper arms. The set of connectors includes a second connector having a structure to receive and be connected to at least two different wiper arms that are part of a second class of wiper arms. The set of connectors includes a third connector having a structure to receive and be connected to at least two different wiper arms that are part of a third class of wiper arms, wherein the first class, the second class and the third class are different from one another.

A wiper structure is provided, including a wiper accessory, a wiper body, and an arm. The wiper accessory features a connecting body with an elastic part located at one end and a pivot slot situated beneath the connecting body. The wiper body is equipped with an accessory base that includes a pivot axle pivotally connected to the pivot slot. The arm includes a rod part and a cover. The arm is mounted on the wiper accessory. Clamping parts are positioned on two sides of the connecting body, each featuring a hollow-shaped clamp groove to clamp the accessory base. A lower edge of each clamp groove includes a flat portion and slopes downward towards the elastic part. Inner walls of the arm include stop edges that abut the flat portions of the lower edges to limit the arm on the connecting body.
