<p>The air deflecting element (8) is rotatably attached to the main bridge (1) of the wiper blade. The rotation of the air deflector element (8) about its axis of rotation (14') is caused by the oscillations (A2) of the wiping element (6) via a flexible element (12) and via a gear (toothed wheels 14, 15). The gear inverses the direction of rotation (B2, C2) and thus the distance (D) between the lower edge of the air deflecting device (8) and the surface to be wiped (7) remains constant during the oscillating movement of the wiper blade. Each air deflecting device comprises two gears (14, 15), two flexible elements (12) and two connecting means (9, 10) for connecting it to the main bridge (1) of the wiper blade.</p> |
