Device for detachably linking a wiper blade with a wiper arm
First Claim
1. Device to detachably connect a wiper blade (12) to clean windows, particularly of motor vehicles, to a driven wiper arm (10) featuring a wiper blade holder (50 or 150) and the wiper blade that can be placed on the window (20) with a long-stretched-out, rubber elastic wiper strip (18) features a band-like, long-stretched-out elastic supporting element (16) that is curved in the longitudinal direction over its band surfaces (15, 17) on whose lower, concave band surface (17) the wiper strip (18) is arranged parallel to the longitudinal axis and on whose outer convex band surface a connecting element (26) sits, which features two parallel wall surfaces (36) that are aligned in a vertical plane on the band surface and extend in the longitudinal direction of the wiper blade, whereby a pivot pin (42) projects from each wall surface and whereby the longitudinal axes of the two pivot pins are aligned with one another, characterized in that an adapter (66 or 166) that can move in a pendulum fashion is positioned on the two pivot pins (42) of the connecting element (26), and said adapter features means to connect to the wiper blade holder (50 or 150) of the wiper arm (10).

Abstract
A device is proposed which is used to detachably connect a wiper blade (12) to clean windows, particularly of motor vehicles, to a driven wiper arm (10) featuring a wiper blade holder (50 or 150), whereby the wiper blade (12) that can be placed on the window (20) with a long-stretched-out, rubber elastic wiper strip (18) features a band-like, long-stretched-out elastic supporting element (16) that is curved in the longitudinal direction over its band surfaces (15, 17) on whose lower, concave band surface (17) the wiper strip (18) is arranged parallel to the longitudinal axis. On the outer convex band surface (15) of the supporting element (16) sits a connecting element (26), which features two parallel wall surfaces (36) that 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 (42) 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 (66 or 166) that can move in a pendulum fashion is positioned on the two pivot pins of the connecting element (26), and said adapter features means to connect to the wiper blade holder (50 or 150) of the wiper arm (10).

- 20. Connecting element for the articulated connection of a wiper blade to clean windows, particularly of motor vehicles, to a driven wiper arm, which features a cross-section that is essentially T-shaped at least in sections, whose T-head facing the supporting element is connected to it, whose T-foot extends in the longitudinal direction of the wiper blade and that is provided with the one articulation half that is embodied as an articulated bolt, characterized in that the articulated bolt features two pins aligned coaxially with one another that project from the two wall surfaces (36) of the T-foot (28) facing away from one another in order to connect additional articulation means in an articulated manner.
