WINDSCREEN WIPER DEVICE

A window wiper device (1), in particular for a rear window wiper of a motor vehicle, with a wiper motor which, via a gear arrangement (3) accommodated in a gear housing (2), drives an output shaft (4), which actuates a wiper lever, wherein, in order to transmit a rotary movement of the wiper motor into an oscillating rotational movement of the output shaft (4), the gear arrangement (3) has a conversion gear (5) which comprises a worm wheel (11), a connecting rod (6) which is connected in a hinged manner to the worm wheel (11), and a toothed segment (8) which is connected in an articulated manner to the connecting rod (6), is mounted rotatably about an axis of rotation in the gear housing (3) in a positionally fixed manner and meshes with a pinion (9) arranged on the output shaft (4), which window wiper device is characterized in that the toothed segment (8) is designed in such a manner that a central tooth axis (Z) formed by the arrangement of the teeth of the toothed segment (8), and the axis of rotation (D) of the toothed segment (8) are offset with respect to each other by a distance (V).
