Windscreen wiper device for motor vehicle, has transmission whose converting unit converts rotation of drive shaft into swing movement of output shaft that is rotatably connected to output pinion corresponding to hollow wheel

摘要

The device (10) has a drive unit (12) provided with a transmission (14). A driving part (16) is equipped with a drive shaft (18). The transmission has a converting unit for converting rotation of the drive shaft into a swing movement of an output shaft (34) of the drive unit. The output shaft is rotatably connected to an output element (32) i.e. output pinion, corresponding to a hollow wheel (28), where the hollow wheel is driven by a rod (24) articulated eccentrically at a worm wheel (22) of the driving unit.
