Abstract
A drive unit for wiper assemblies includes a housing (2, 3; 91) surrounding a drive motor, which is associated with a gear (13, 30, 50, 60, 80, 90), whose drive shaft (5, 40, 65, 97) drive wiper components. On the housing (2, 3; 91), a connecting point (27) for a control and regulating electronics, as well as for connecting to an on-board system of a motor vehicle and a position detector (12), are provided. The drive shaft (5, 40) lies either coaxial to the drive shaft of a rotationally symmetrical motor and drive unit (1, 30, 50, 80) or the axis of symmetry (93) of the motor and gear unit (60, 90) lies in a mirror plane (78).
