Embodiment Construction

[0012] For the wiper blade 12 only two supports 14 in the form of two parallel spring bars are shown. The connecting element 16 in the form of a metal clamp is fastened to the spring strip, for example by welding and / or by means of clamps 24 . The clips are formed laterally on the base part 22 . The connecting part 16 has a substantially U-shaped cross-sectional profile, wherein on each longitudinal side the two side walls 26 , 28 are bent by approximately 90° from the base part 22 away from the support part 14 . A recess 36 is provided between the longitudinal side walls 26 , 28 of the connecting element 16 . The side wall 26 pointing toward the free end of the wiper blade 12 supports a bearing bolt 30 . The bearing bolt 30 protrudes laterally outward beyond the side wall 26 with a bearing head 32 . The side wall 28 at the other end of the adapter 18 is bent inwards at the drive-side end by approximately 90° and forms an end wall 34 .

[0013] The adapter 18 is mounted pi...

Abstract

The present invention relates to a device for articulating the wiper blade (12) to the water scraping arm (10) of the water scraper, the device includes a connecting element (20) which is fixedly connected with the water scraping arm (10) and a connecting component (16) that is fixedly connected with the supporting component (14) of the wiper blade (12), the connecting component (16) is provided with at least one side wall (26, 28 and 44) oriented to the connecting element (20) from the baseboard component (22) at each longitudinal side surface, these side walls supports the bearing belt (30)and a plastic adapter (18) is rotatably supported on the bearing belt (30), wherein the adapter (18) is fixed to the profile of the connecting element (20) which is open to the connecting component (16) with the setting elements (46, 56 and 58) and holding elements (68, 60 and 62), and one part (44 and 52) are inserted into the space between the side walls (26 and 28). The invention puts forward that one part (38 and 40) of the side wall of the adapter (18) covers the side wall (26 and 28) of the connecting component (16) from the outside and the other part (44) of the side wall covers the side walls (26 and 28) of the connecting component (16) from the inner side with the mode of inward offset.

Description

technical field [0001] The invention relates to a device for the articulated connection of a wiper blade to a wiper arm of a wiper. Background technique [0002] Such a device is known from WO 02 / 40328 A1. The device consists of a connecting piece in the form of a metal clamp, a plastic adapter and a connecting element which is fixedly connected to the wiper arm. The connecting piece is fastened to the wiper blade carrier in the form of two parallel spring bars by means of clamps and / or by welding. The connecting piece has a u-shaped cross-sectional profile in which the side walls are bent by approximately 90° away from the support piece starting from the floor piece adjacent to the support piece. An opening is provided in the side wall, into which the bearing pin is inserted in a rotationally fixed manner. An adapter with a sleeve is mounted pivotably on the bearing bolt, which is inserted laterally between the side walls of the connecting part. The adapter has a positi...
