The windscreen wiper assembly comprises an elongated arm having two opposite ends, two elongated links, two elongated blade holders, and an elongated blade. The arm has an adjusting hole at each end. The arm has a pair of axially aligned projections extending into each hole bore. The arm has a downward facing round connecting opening. Each link has a mortise at a first end receiving one of the blade holders. A clamping coupling at a second end for holding the blade. A cylinder is intermediate the ends. The cylinder has an elongated trapezoidal depression. A portion of the cylinder is rotatably received into the downward facing round connecting opening to enable relative rotation about a longitudinal axis of the link between the link and the arm. The blade is coupled with the clamping coupling of each link and with the blade holders. |
