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 invention relates to a device for hingedly connecting a wiper blade (12) to a wiper arm (10) of a wiper, comprising a connecting element (20) fixedly connected to the wiper arm (10) and a The support part (14) of the water sheet (12) is fixedly connected to the connecting part (16), which has at least one side pointing towards the connecting element (20) on each longitudinal side starting from the base part (22) Walls (26, 28, 44), these side walls support the bearing bolts (30), on which the plastic adapter (18) is rotatably supported, wherein the adapter (18) passes through The positioning elements (46, 56, 58) as well as the retaining elements (68, 60, 62) are fixed in the contour of the connecting element (20) open towards the connecting part (16) and embedded with a part (44, 52) in the side wall ( 26, 28) in the space between. It is proposed that a part (38, 40) of the side wall of the adapter (18) covers the side wall (26, 28) of the connecting part (16) from the outside, while another part (44) of the side wall is biased inwardly The side walls (26, 28) of the connection part (16) are covered from the inside.

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 according to the preamble of claim 1 . 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 conn...
