Abstract:
A wiper apparatus for windows of motor vehicles, comprising at least one wiper arm (18), guided on the motor vehicle and driven in pendulum motion, wherein on a free end of the wiper arm remote from a pendulum shaft (88), a wiper blade (10), elongated transversely to a direction of the pendulum motion (double arrow 86) and capable of being pressed against the window (28), is separably hinged via a connection device (14) that has first and second pivotally connected coupling elements (22 and 16) associated with the wiper arm and the wiper blade, respectively, wherein a pivot axis (54) of the device extends substantially in the pendulum direction, and the wiper apparatus has at least one support shoulder (44, 46; 68), solidly connected to the first coupling element on the wiper arm and pointing toward the pendulum shaft (88), said support shoulder is located opposite an associated interception shoulder (62), solidly connected to the second coupling element on the wiper blade and pointing away from the pendulum shaft (88), wherein at least one of the two shoulders (44, 46, 68; 62) can be moved counter to a restoring force all the way out of the opposed position relative to the other shoulder (62; 44, 46, 68), and further comprising, said second coupling element having a base body (48) with spring tongues (58) extending therefrom said spring tongues deflectable substantially in a direction of the pivot axis (54), and wherein the interception shoulder (62) is disposed on a free end of one of said spring tongues.
