Abstract
A window lifting arrangement for an automotive vehicle and the like includes a support which defines the axes x, y, z of a system of rectangular coordinates. A window pane is mounted for movement relative to the support, the movement having a principal component in the direction of the y-axis, the pane and its direction of movement being arcuate about an axis of curvature transverse to the y-axis. A guide rail elongated in the direction of the z-axis is secured to the pane. An operating arm is mounted on the support for angular movement about a pivot axis and has a free end drivingly connected to the guide rail for movement of the free end longitudinally of the guide rail. The pivot axis is inclined relative to the plane defined by the y- and x-axes at a small acute angle, and preferably relative to a plane defined by the x- and y-axes at another small acute angle.
