ABSTRACT:
A windshield wiper system includes two windshield wipers of which each is mounted on a separate wiper shaft and may be driven to and fro by a separate motor between an inner reversing position and an outer reversing position, which windshield wipers are at least partially superposed in their inner reversing position and rotate in opposite directions through one wiping cycle. The two windshield wipers are moved without collision even though they wipe an overlapping area. The first windshield wiper is driven by its associated motor with a greater angular velocity of the output shaft than the second windshield wiper is driven by its motor. In addition the first windshield wiper is stopped for a predetermined time in its inner reversing position between two wiping cycles.
