Abstract:
1. An attachment device ( 10 ) for connecting a wiper arm to a wiper blade ( 12 ), which is rigidly connected to an attachment element ( 22 ) of the attachment device ( 10 ), whereas an adapter ( 60 ) is connected to the attachment element ( 22 ) in an articulated fashion and is detachably fastened to the wiper arm, characterized in that said attachment element ( 22 ) and the adapter ( 60 ) are produced from plastic, and said adapter ( 60 ) has a longitudinal bar ( 74 ) extending along a longitudinal center plane, said bar supporting a bearing pin ( 76 ), which runs transverse to a longitudinal direction in a central region of the bar, in that the longitudinal bar ( 74 ) and the bearing pin ( 76 ) protrude to a certain extent beyond side walls ( 62 ) of said adapter ( 60 ) to the attachment element ( 22 ), a part of said longitudinal bar ( 74 ) protruding to an attachment part ( 26 ) of the attachment element being guided between two contact surfaces ( 80 ), which run in the longitudinal direction and are offset in relation to one another, so that in the assembled position, each longitudinal side of said longitudinal bar ( 74 ) rests against one of the contact surfaces ( 80 ) and said longitudinal bar ( 74 ) can be rotated through an angle α about a vertical axis between the contact surfaces ( 80 ) and in that the length of the bearing pin ( 76 ) is dimensioned so that in the assembled position, both ends of the pin engage in bearing holes ( 50 ) in side walls ( 42 ) of the attachment part ( 26 ).
