The present invention provides a wiper for a vehicle including: an adapter mounted on a wiper operation arm; an adapter holder configured to hold the adapter; a frame holder coupled to the adapter holder; left and right primary levers disposed on left and right ends of the frame holder, whose respective one ends are detachably coupled to the left and right ends of the frame holder; left and right secondary levers respectively connected to the other ends of the left and right primary levers by two lever joints; four tertiary levers having couplers respectively formed thereon; and a blade of a rubber material, wherein each of the left and right primary levers, and the left and right secondary levers is made of an elastic leaf spring of a metal material, and the four tertiary levers are made of elastic engineering plastic.

The invention is based on a wiper blade adapter device with an adapter basic body (10) which is provided to be fixedly connected to a wiper blade component (12), and with an adapter unit (14) which is provided for releasable coupling to a wiper arm adapter (16), and wherein the adapter unit (14) is provided to be connected to the adapter basic body (10) via a latching connection. It is proposed that the adapter unit (14) comprises at least one latching means (18) for latching to the adapter basic body (10), said latching means being provided to be at least partially deflected in the direction of a longitudinal centre plane (22) of the adapter unit (14) during assembly with the adapter basic body (10).

The present invention relates to a wiper arm head adapted to be connected to a wiper arm body, the wiper arm head comprises: a base end section, a front-end section, and a body section having a pair of left and right side walls longitudinally extending from the base end section towards the front-end section. The wiper arm head comprises a first retainer connection assembly and a second retainer connection assembly formed integrally with the wiper arm head and configured to connect the wiper arm head to the wiper arm body, which comprises a first retainer and a second retainer to hold a first wiper blade and a second wiper blade respectively.

A vehicle wiper blade comprises a blade support part and a lip part coupled swingably with the blade support part via a neck. The lip part comprises polyurethane. The polyurethane comprises a reactant of a composition including an isocyanate compound which includes diisocyanate and tri- or higher functional polyfunctional isocyanate, and an alcohol which includes tri- or higher functional polyfunctional alcohol. The diisocyanate has an aromatic ring in a molecule. When a molecule of the polyurethane is ionized with a mass spectrometer of a direct sample injection system, then obtained M1, M2 and M3 satisfy the following relation: M2/M1 is 0.001 to 0.028, M3/M1 is 0.020 to 0.110, and M2/M3 is 0.013 to 0.300, and a concentration of the polyfunctional alcohol in the polyurethane is 0.12 mmol/g to 0.65 mmol/g.
