The invention is based on a wiper connecting unit with a basic body () for connecting a wiper blade adapter () to a wiper arm () of a wiper. It is proposed that the basic body () has a spoiler receiving region () arranged on one side () of the wiper arm.

Wiper connecting unit

The invention relates to a connecting device which has a connecting element () of flat beam design fixed to a wiper blade () and an adapter () joined to said connecting element in an articulated manner, and also a joining element () that is joined to a wiper arm () and into the u-shaped cross-sectional profile of which the adapter () is inserted and, by means of a spring tongue () arranged on the top wall () thereof, is fixed to a pushbutton (), the connecting element () having a central web () running in the longitudinal direction of the wiper blade () and bearing a hinge shaft () projecting on the long sides thereof, which is mounted in laterally flexible hubs () in side walls () of the adapter (). According to the invention, the outwardly facing walls of the adapter (), namely the side walls (), the top wall (), and the end walls (), have a general wall thickness of at least two millimeters, and the hubs () are to be formed as blind holes, the cylindrical surfaces of which form radial sliding surfaces () and the end faces of which form axial sliding surfaces (), which are highly polished with an arithmetic mean roughness of Ra&#x3c;0.2&#x3bc;, and that the sliding surfaces () be the sole contact surfaces between the connecting element () and the adapter ().

Connecting device

The invention is based on a wiper blade () with a wiper strip () which has a wiper lip () and a head strip () which is integrally formed on said wiper lip and, in a first longitudinal channel (), has a supporting element in the form of a spring rail () with a flat cross section, and has a spoiler () on that side which faces away from the wiper lip (). It is proposed that the spoiler () surrounds the head strip () on its longitudinal sides by means of guide rails ().

Wiper blade

A wiper lever () with a wiper arm () and a wiper blade () linked to it to clean windows of motor vehicles in particular is proposed, whose wiper blade is provided with a band-like, long-stretched-out, elastic supporting element () that is curved in the longitudinal direction over its band surfaces (), which features a rubber elastic wiper strip () that can be applied to the window on its concave-curved band surface (), on whose convex-curved band surface () an articulated part () sits, on which an adapter () is positioned so that it can move in a pendulum fashion, which has walls () aligned in the longitudinal direction of the wiper blade and standing on the band surfaces of the supporting element () with planes situated at a distance from one another, and locking means () are arranged on the adapter that are moveable against a restoring force, which cooperate with counter-locking means () of the wiper arm. A particularly operationally reliable connection between the wiper arm and the wiper blade to form the wiper lever is achieved if the locking means are arranged on at least one of the two walls () and are moveable essentially transverse to the surfaces of these walls.

Wiper lever comprising a wiper arm and a wiper blade which is connected to the same in an articulated manner

Wiper lever () with a driven wiper arm () and a wiper blade () linked to it for cleaning the windows of motor vehicles in particular, which is provided with a band-like, long-stretched-out, elastic supporting element () that is curved in the longitudinal direction over its band surfaces (), which features a rubber elastic wiper strip () that can be applied to the window on its concave curved band surface (), on whose convex curved band surface () a coupling element () sits to connect the wiper blade to a coupling piece () of the wiper arm and the articulated connection is covered by a cap () that is held on the wiper blade. A well-designed, pleasing transition between the wiper arm and the wiper blade of the wiper lever along with good protection of the articulated connection that exists between these two components of the wiper lever are achieved without impairing the handling of the securing means in that this articulated connection has at its disposal means to secure the connection between the wiper arm () and the wiper blade () that can be actuated with at least one handle () and that the cap () accommodates the handle ().

Wiper lever comprising a wiper arm and a wiper blade which is connected to the same in an articulated manner, for cleaning windows, especially windows pertaining to motor vehicles

A device is proposed which is used to detachably connect a wiper blade () to clean windows, particularly of motor vehicles, to a driven wiper arm () featuring a wiper blade holder (or), whereby the wiper blade () that can be placed on the window () with a long-stretched-out, rubber elastic wiper strip () features a band-like, long-stretched-out elastic supporting element () that is curved in the longitudinal direction over its band surfaces () on whose lower, concave band surface () the wiper strip () is arranged parallel to the longitudinal axis. On the outer convex band surface () of the supporting element () sits a connecting element (), which features two parallel wall surfaces () mat are aligned in a vertical plane on the band surface and extend in the longitudinal direction of the wiper blade and that a pivot pin () projects from each wall surface, whereby the longitudinal axes of the two pivot pins are aligned with one another. An especially simple embodiment of the articulated connection with an integrated connecting device is achieved if an adapter (or) that can move in a pendulum fashion is positioned on the two pivot pins of the connecting element (), and said adapter features means to connect to the wiper blade holder (or) of the wiper arm ().

Assembly of the cap on the wiper blade in its correct position on the wiper blade is achieved in a simple manner if the supporting element is provided with at least two limit stops () each pointing in opposite longitudinal directions of the wiper blade () to which corresponding counter limit stops () of the cap () are assigned.
