<p>A vehicle windscreen wiper device has a wiper blade which during operation sweeps a wiping field between two oscillating reversing positions. Said blade is connected via a wiper arm to a pendulum shaft and can be placed in a rest position located, when viewed in an oscillating direction, in front of the wiping field. The wiper device has a drive device which has an electric drive motor which is connected to a crank component of a pendulum drive and which transmits the rotary movement of the drive motor as an oscillating movement to the pendulum shaft. The crank is supported by a shaft in an eccentric bushing which is rotationally guided with respect to a device housing between two positions so that the axis of rotation of the crank moves between an oscillating operating position and an additional position which provides the wiper rest position. In order to imitate the wiping movement of the wiper blade immediately the wiper device is switched on, the eccentric bushing has a separate adjusting device independent of the pendulum drive.</p> |
