Wiper device, especially for windshields of automobils

摘要

A wiper system has a driveable wiper arm (20) guided at one end on the motor vehicle. A long-straggling wiper blade (12) capable of being placed against the window (16) with a wiper strip (22) is detachably hinge-mounted via a connection device (18) that has a pivot bolt (24) on the arm side. The axis of articulation of the pivot bolt extends substantially transversely to the longitudinal direction of the wiper blade in the working direction of the wiper system. The system includes a coupling part (26) on the wiper-blade side in a center section of the wiper blade (12) on its side opposite from the window (16) having a bore-like bearing receptacle for a pivot bolt (24). The bearing receptacle is provided with a bottleneck (94) capable of being expanded elastically to the diameter (92) of the pivot bolt.
