Abstract
A wiper apparatus is proposed that is used to clean windows of motor vehicles. The wiper apparatus has a wiper arm (18), guided on the motor vehicle and driven in pendulum motion, on whose free end, remote from the pendulum shaft (88), a wiper blade (10), elongated transversely to the pendulum direction (double arrow 86) and capable of being pressed against the window (28), is separably hinged via a connection device (14) that has coupling elements (22 and 16) associated with the wiper arm and the wiper blade, respectively, wherein the pivot axis (54) extends substantially in the pendulum direction, and the wiper apparatus has at least one support shoulder (44, 46 and 68), solidly connected to the wiper arm and pointing toward the pendulum shaft (88), which shoulder is located opposite an associated interception shoulder (62), solidly connected to the wiper blade and pointing away from the pendulum shaft (88). To assure problem-free mounting of the wiper blade on the wiper arm and problem-free removal of the wiper blade from the wiper arm, even if for structural reasons the wiper arm cannot be raised in a plane that is vertical to the window, transverse to the wiping direction, at …
