Abstract: A sliding sunroof including a cover, a device for moving the cover forward and rearward, a device for lifting the rear of the cover upward from an open position to a closed position and further upward to a vented position, devices for locking the cover in these positions, and a rear cover support. The lifting device includes a ramp for lifting the cover into the open position and a rack and pinion gear combination for lifting the cover into the vented position. The lifting device is attached to the rear cover support and includes a ramp guide and a lift arm slidably engaging a slot in the ramp guide.

Abstract: A sliding sunroof for a vehicle having an opening in its roof. The sunroof includes a housing, a sunroof cover, a device for moving the cover forward and rearward, a device for lifting the cover upward from an open position to a closed position and further upward to a vented position and downwardly in the reverse direction, and locking mechanisms for securely locking the sunroof in these positions. The locking mechanisms include a ramp guide attached to the moving device, and a lift arm attached to the cover. The lift arm has a portion that rides up the ramp guide. The locking mechanisms include a lock slide slidingly attached to the ramp guide and having a slanted portion positioned above the riding up portion when the cover is in its open position for preventing the riding up portion of the lift arm and the cover from being vertically displaced in the open position.
