Abstract
Abstract An automobile rear glass door has a substantially flat main body portion and is angled at each side thereof to have side portions which cooperate with adjacent outer surfaces of a vehicle body when the rear door is in the closed position to define the contour of the vehicle. A weatherstrip is disposed on the vehicle body outer surfaces so as to contact the main body portion of the door glass inboard of the transition portion between the door's side portions and the door's main body portion when the rear door is in the closed position, thereby providing a positive environmental seal therebetween and improving the fit between the rear door edge and the adjacent vehicle body section.
