Abstract:
1. Wiper lever ( 10 ) with a wiper arm ( 12 ) and a wiper blade ( 14 ) linked to it to clean windows ( 15 ), which is provided with a band-like, elongated, elastic supporting element ( 22 ) that has opposite concave-curved and convex-curved band surfaces ( 26 , 28 ) and that is curved in the longitudinal direction over its band surfaces ( 26 , 28 ), which features a rubber elastic wiper strip ( 30 ) that can be applied to the window ( 15 ) on its concave-curved band surface ( 26 ), on whose convex-curved band surface ( 28 ) an articulated part ( 20 ) sits, on which an adapter ( 40 ) is positioned so that it can move in a pendulum fashion, which has walls ( 42 ) aligned in the longitudinal direction of the wiper blade and above the band surfaces of the supporting element with planes situated at a distance from one another, and moveable locking means ( 68 , 72 ) are arranged on the adapter, which cooperate with counter-locking means ( 66 ) of the wiper arm, characterized in that the locking means are arranged on at least one of the walls ( 42 ) and are moveable essentially transverse to the surfaces of these walls, characterized in that the adapter ( 40 ) has a U-shaped cross-section at least in sections, whose U-legs ( 42 ) form the walls between which supporting walls ( 34 ) embodied on the articulated part ( 20 ) suitably dip, characterized in that the adapter ( 40 ) suitably grips over two longitudinal walls ( 34 ) of the articulated part ( 20 ), which are situated at a distance from one another, with its U-legs ( 42 ), that articulation means ( 50 , 38 ) are arranged on the longitudinal walls and on the U-legs ( 42 ) and that the locking means ( 72 ) of the adapter ( 40 ) that is composed of an elastic material are located on an extension ( 70 ) of the U-legs of the adapter extending beyond the longitudinal walls ( 34 ), characterized in that the wiper arm ( 12 ) that is driven in a pendulum fashion about a pendulum axis accommodates the adapter ( 40 ) with a connecting piece ( 18 ) that is U-shaped in cross-section and that the extension ( 70 ) of the adapter extends towards the pendulum axis ( 16 ), and characterized in that the locking means ( 72 ) of the adapter ( 40 ) that are preferably moveable against a restoring force are located on the outer side of the extension ( 70 ) facing U-legs ( 52 ) of the connecting piece ( 18 ) that is provided with the counter-locking means ( 66 ) of the wiper arm ( 12 ).
