The drive (1) has worm wheels (4, 5) engaged with screws (3) and driving output shafts (6, 7) of windscreen wipers, where a reversible electric motor (2) and a transmission are equipped in the drive unit. The worm wheels are assembled in series along large sides of the screws such that the windscreen wipers are actuated in synchronism. The worm wheels are installed according to a plane symmetry with respect to longitudinal axis of the screws such that the windscreen wipers are actuated in opposition. |
