Windscreen wiper for front glass pane of vehicle i.e. aircraft, has bent arm comprising wiping part with wiping blade, and connection part integrally assembled to wiping part, where connection part swivels around axis and comprises airfoil

摘要

The wiper has a bent arm comprising a wiping part with a wiping blade, where the wiping part is parallel to streamline flow around of a moving vehicle when the wiper is in stop position. A connection part swivels around an axis (R), and is integrally assembled to the wiping part. The connection part is transversal to the streamline flow when the wiper is in stop position. The connection part comprises an airfoil (8) whose leading edge (9) is directed towards upstream of the streamline flow. A trailing edge (10) of the airfoil is directed towards the downstream of the streamline flow.
