Abstract
A windshield wiper system (WWS) is provided. The WWS includes a wiper blade movable across a maximum sweep angle, a sector gear, a wiper arm coupled at opposite ends thereof to the wiper blade and the sector gear and a bi-directional motor. The bi-directional motor includes a motor shaft and a pinion gear disposed on the motor shaft to engage with the sector gear. The bi-directional motor is operable to drive rotations of the pinion and sector gears in opposite directions via the motor shaft to thereby drive opposite movements of the wiper blade via the wiper arm, respectively, without risking loss of engagement between the pinion and sector gears.
