Abstract

An operating mechanism for a roof opening closure panel includes a track extending longitudinally of the vehicle. A roller and a lifting link are respectively pivotally attached to the leading end and trailing end of the closure panel and are captured for sliding movement in the track. A ramp member is slidably captured in the track intermediate the roller and the lifting link and has an inclined surface which lifts the roller vertically when the ramp member is forced beneath the roller. A connecting rod extends between the ramp member and the trailing end of the lifting link to provide a fixed length therebetween. A drive cable is connected to the trailing end of the lifter link for moving the lifter link fore and aft in the track. When the closure panel reaches its full forward position its forward movement is stopped and continued forward movement of the trailing end of the lifter link by the drive cable causes the leading end of the lifter link to be moved vertically to thereby lift the trailing end of the closure panel vertically. This further forward movement of the trailing end of the lifter link also moves the connecting rod and ramp member forwardly to drive the ramp member beneath the front roller thereby lifting the leading end of the closure panel simultaneous with the vertical lifting of the trailing end of the closure panel.
