Motor-vehicle side door

摘要

A motor-vehicle door has a generally annular door frame having an inner side and outer side respectively releasably connected to inner and outer door panels. A hinge is connected to one vertical edge of the frame between the sides and a latch to the opposite edge. A window pane is vertically displaceable in and above the frame and the mechanism for operating this window and for operating the latch are fixed to the inner panel. The frame is formed by a pair of frame parts together forming a tubular box-girder structure on the two upright sides and lower edge of the door for maximum rigidity.
