Abstract: The sliding section (4) is fastened to the window-bottom section (6) by means of screws passing through the section (4) and tabs (8) fastened to the section (6); in one of the tabs )8) a downwardly open V-shaped notch (13) is made, the inclined sides (13a, 13b) of which form guiding ramps for a projecting tab (12) of the sliding section (4), permitting the automatic positioning of the section (4) relative to the window-bottom section (6) in such a way that their respective holes for fastening by means of the screws are in perfect coincidence; the arrangement of the means (12, 13) for the automatic centering of the section (4) relative to the section (6) reduces the time required for their assembly on the door assembly line.

Abstract: A device which includes two matching sections (7, 8), with a first section (7) designed to be fastened to the bottom of a window (6) and the second section (8) arranged to be articulated on an arm (3) of a window raiser. The cross-sections of these sections are such that the first section (7) can be locked into the second section (8) by snapping and a result of a displacement lying substantially in the general plane of the window (6) and of the movement of the latter. The matching cross-sections of the two sections (7, 8) provide a degree of rotation and a degree of translational motion between the two sections. This device makes it possible to carry out the installation of windows on window raisers automatically by robot on motor-vehicle assembly lines because of the simplification of the necessary movements.
