ABSTRACT:
The invention relates to a device for the detachable, articulated connection of a wiper blade (14) for cleaning windows, in particular of motor vehicles, to a wiper arm (12) driven on one end, which is provided with a first coupling half (26) on its other, particularly, its free end (13) and a connecting device (24) featuring a second wiper-blade-mounted coupling half (28), which is arranged on the upper band side (23) of a band-like, long-stretched-out, elastic supporting element (22), on whose other, lower band surface, (21) a rubber-elastic wiper strip (20) that can be placed on the window (19) is situated, and the wiper-blade-mounted coupling half (28) has a pivot pin (46) aligned transverse to the wiper blade's longitudinal extension and transverse to the placement direction (arrow18) to connect to the wiper arm (12), whose longitudinal axis forms the articulation axis (17) of the device and which is allocated to a pin rest receptacle (62) present on the wiper-arm-mounted coupling half (26). A particularly reliable and enduring connection between the wiper-blade-mounted coupling half (28) and the supporting element (22) of the wiper blade (14) is achieved if the wiper-blade-mounted second coupling half (28) is embodied as a sheet metal bent part, on which the pivot pin (46) is formed, connected as a single part.
