ABSTRACT:
A drive mechanism for moving a sunroof panel fore and aft along a pair of laterally spaced apart tracks mounting the sunroof panel includes a drive linkage including a pair of first and second links which are provided adjacent to each track. Each of the pair of links has outboard ends which are connected to the rear end of the sunroof panel and to the roof rearward of the sunroof opening, and inboard ends which are pivoted together to define an apex. A rotatable threaded drive shaft extends longitudinally of the body equidistant between the tracks. A drive bar extends transversely of the roof and has its ends slidably engaging with the apexes of first and second links and has a central portion threadedly engaging with the drive shaft so that drive shaft rotation drives the drive bar fore and aft and the drive bar in turn drives the apexes fore and aft. The apexes travel in an arcuate path during the fore and aft movement and are preferably supported by an arcuately shaped guide tracks which attached to the roof and slidably engaging with the apexes of the drive linkages to define and support the arcuate movement of the apexes during fore and aft movement of the sunroof panel and the drive bar.
