Screen wiper device for a motor vehicle has a wiper blade to move like pendulum and a motion device with an electro-active polymer

摘要

A wiper (12) can be moved to remove moisture and/or dirt on a windscreen (14). A motion device with an electro-active polymer moves a wiper blade on the windscreen and can set the wiper blade in a pendulum motion. When operating, the wiper blade is pressed with an adjustable force on the windscreen. An independent claim is also included for a device for adjusting an element for a motor vehicle, with an adjustable element, a drive mechanism and a electro-active polymer for performing a driving function.
