Windscreen wiper for land, water and air craft has wiper lip on basic support which has pipeline in longitudinal direction and is flexible to deform against windscreen in dependence on pressure in pipeline

摘要

The windscreen wiper has a wiper lip on a basic support which has in its longitudinal direction at least one first pipeline and is designed to be flexible so that it can be deformed in dependence on the pressure inside the pipeline. This pipeline is connected to a pressure generating device (13) or pressure reservoir.
