Abstract
A wiper apparatus is proposed, which serves to clean windows of motor vehicles. The wiper apparatus (10) has a driven wiper arm (12) guided on one end on the motor vehicle, on the free end (11) of which arm an elongated wiper blade (14) that can be pressed with a wiper strip (18) against the window (20) is separably pivotably connected via a connection device (16), which on the side toward the arm has a pivot bolt (40) whose hinge axis extends essentially transversely to the longitudinal direction of the wiper blade (14) and which toward the wiper blade, in a middle portion of the wiper blade on its side remote from the window, has a coupling part (34) with a bearing recess (54) for the pivot bolt (40), which can be introduced into the bearing recess (54) via a mounting channel (48), and the insertion opening (52) of the mounting channel is disposed on the side of the coupling part (34) remote from the window (20). The mounting channel (48) has two partial channels (50 and 51), which form an angle a&agr; of less than 180° with one another, and the one partial channel (50) has the insertion opening (52) for the pivot bolt (40), while the other partial channel (51) opens into the…
