Problems solved by technology

[0003] However, the exposed tongue can also be deflected unintentionally, for example by rotating brushes in a car washing system, so that the wiper blade is released from the wiper arm and causes damage to the vehicle

Embodiment Construction

[0042] belong figure 1 The wiper lever 10 shown has a wiper arm 12 and a wiper blade 14 articulated thereon. The wiper arm 12 is driven pivotally at one end about an axis 16 . In order to be able to easily realize the articulated connection between the wiper arm and the wiper blade, the wiper arm is provided with a connecting block 18 ( figure 1 and 4 ), on which the wiper blade 14 with a hinge 20 can be connected via an adapter. The articulation 20 is fixedly connected to a carrier element 22 of the wiper blade 14, which in this exemplary embodiment has two spring bars 24 which lie in a common plane and are spaced apart from each other and are indicated by dotted lines. ( figure 2 ). The thus formed strip-shaped longitudinally extending spring-elastic support element 22 is bent in its longitudinal direction on its strip surfaces 26 and 28 ( figure 1 ). On its concavely curved strip surface 26, a rubber-elastic wiper strip 30 that can be attached to the glass window 15...

Abstract

A wiper lever (10) for cleaning, in particular of motor vehicle windows, having a wiper arm (12) and a wiper blade (14) hinged to the wiper arm is proposed, the wiper blade being arranged There is a strip-shaped longitudinally extending, spring-elastic, curved support element (22) in the longitudinal direction on its strip surface (26, 28), which has a concavely curved strip surface (26) on its A rubber-elastic slat (30) that can be attached to the glass window, on the convex curved belt surface (28) of the slat, a hinge (20) is placed, on which hinge An adapter (40) is supported, which has facing walls (42) in the longitudinal direction of the wiper blade and in mutually spaced planes standing on the belt surface of the support element (22); and A locking mechanism ( 72 ) movable against a restoring force is provided on the adapter and cooperates with a counter locking mechanism ( 66 ) of the wiper arm. If the locking mechanism is arranged on at least one of the walls (42) and can be moved substantially transversely to the surface of these walls, a kind of locking can be formed between the wiper arm and the wiper blade. In particular, an operationally reliable connection is used to form the wiper lever.

Description

technical field [0001] The invention relates to a wiper lever for cleaning windows, a wiper blade for cleaning windows, and an adapter for releasably connecting the wiper blade to a wiper arm. Background technique [0002] The wiper lever includes a driven wiper arm, to which is hinged at a distance from its drive end a wiper blade which is slidable over the window to be wiped, transversely to its longitudinal extension. The articulation axis of the wiper blade extends substantially in its sliding direction. This articulation is particularly interesting since the generally spherically curved glass window to be wiped (for example the windshield of a motor vehicle) is not part of the spherical surface. Therefore, the wiper blade must always be able to adapt to the position and change of the glass surface during its wiping movement relative to the plane of movement of the wiper arm. For this purpose, an oscillating movement of the wiper blade relative to the wiper arm about t...
