Abstract: A removable roof panel arrangement for motor vehicles and the method of installing such panels in which access openings to be covered by the panels are formed at opposite sides of the center of the vehicle body by completely cutting away a transverse section of the roof of the vehicle body and subsequently installing a central frame member which is attached to forward and rearward frame members through a reinforcing member. The construction retains the strength of the original body and the frame members form drainage troughs and support sealing members for engaging the removable panels which form secondary drainage systems to maintain the panels in weather tight relationship to the roof of the vehicle.

Abstract: A window structure for vehicle bodies in which the rear window is hinged and is held in a closed position by a latch arrangement which is accessible only from the interior of the vehicle. The opening of the rear window is provided with a seal which biases the window light towards its open position so that the window can be grasped and moved to a selected fully opened position.

Abstract: A removable roof panel arrangement for motor vehicles and the method of installing such panels in which access openings to be covered by the panels are formed at opposite sides of the center of the vehicle body by completely cutting away a transverse section of the roof of the vehicle body and subsequently installing a unitary frame member which is attached to forward and rearward portions of the original vehicle roof. The construction retains the strength of the original body and the frame members form drainage troughs and support sealing members for engaging the removable panels to maintain the panels in weather tight relationship to the roof of the vehicle.

Abstract: A hatch assembly for vehicle roofs in which an opening is covered by a pair of panels disposed in side by side relationship to each other and being held in position by a latch system which permits the panels to be used in a partially open position or to be completely removed and stowed separately of the vehicle. The framed opening and panels incorporate a sealing system which diverts moisture away from the hatch assembly and allows drainage of water that does enter the hatch assembly.
