Curved motor vehicle window pane raising mechanism - has arm enclosing angle enabling its end to follow curved track

摘要

There are two arms swivelling about two axes, with the second engaging two angled running rails in the mechanism for raising and lowering a pane curved about a transverse axis, esp. in motor vehicle windows. In every activating position the second swivel axis encloses a small acute angle with a reference line vertical to the direction of raising and lowering and bottom pane edge. The angle is such that the end of the second arm released from the first rail is guided on a track following the curved track of the point of contact of this arm with the first rail. This is simple and inexpensive.
