<p>1. A drive device for a sliding panel (PC) of a motor vehicle comprising two guiding slideways which are connected to the part of the body (P) of the vehicle receiving the sliding panel (PC) and in which are engaged respective lateral edges of the sliding panel (PC), a drive device (20, 21, 22, 23) for the automatic control of the movements of the panel (PC) comprising a plate (20) on which is mounted a drive motor (21) whose output shaft supports a movable rotary gearing element (23) and which is itself pivotally mounted on said part of the body (P) to pivot about a pin (25) which is roughly perpendicular to the sliding plane of said panel (PC), and a coupling device comprising a slideway (28) in which is engaged a slide (27) connected to the pivotally mounted plate (20), said slideway (28) acting on a third edge of the panel (PC) and being engaged with the output of the drive device (20, 21, 22, 23), this drive device being characterised in that it further comprises a second gearing element (30) which is connected to said part of the body (P) and along which said movable gearing element (23) is adapted to roll, the plate (20) is slidably mounted in its own plane on its pivot pin (25) and the gearing element connected to the part of the body (P) is a straight rack (30) parallel to the sliding plane of the panel (PC) and connected to an arcuate guide (32) which extends in the same plane and cooperates with a follower element (29) of this guide (32) connected to said plate (20).</p> |
