A pantographic windscreen wiper includes a windscreen-wiper blade (2), a main pivoting arm (9) having a first end (9a) connected to and fast for rotation with a motor-driven shaft (14) and a second end (9b) articulated to the blade (2) about a first pin (6), and a secondary pivoting arm (17) with a first end (17a) connected rotatably to a fixed shaft (20) adjacent the motor-driven shaft (14) and a second end (17b) articulated to the blade (2) about a second pin (7) adjacent the first pin (6). The first and second pins (6, 7) are on the windscreen-wiper blade and are aligned along its length. The first end (17a) of the secondary arm (17) is arcuate and has a spherical recess (19) which snap-engages a spherical head (21) carried by the fixed shaft. The pantographic windscreen wiper has fewer parts, less weight and lower production costs, combined with limited frontal obstruction and easier fitting and removal. <IMAGE> |
