Abstract
A wiper device with a wiper blade for cleaning windows of motor vehicles, in which the wiper blade can be moved back and forth laterally to its longitudinal span by a driven wipe arm which can be connected to the wiper blade and loads the same against the window. The wiper blade has an elongated wiper strip that can be placed against the window and an elongated spring-elastic carrying element, which has a connecting unit for the wiper arm and is disposed parallel to the longitudinal axis of the wiper strip to distribute a contact force over the entire wiper strip length. A particularly effective and low-noise operation of the wiper system is achieved because the contact force of the wiper strip against the window is greater in its center section than in at least one of two end sections of the wiper strip.
