ABSTRACT:
A vehicle door, for example a passenger car door, is supported by a door frame formed by a modular frame structure having a forward frame section, a rear frame section, an upper frame section, and a lower frame section. Additional components and accessories of the door, such as window lift mechanisms and lock mechanisms, are attached to the modular frame structure. At least a portion of each of the forward, lower and rear frame sections is formed from a continuous sectional member such as an extruded sectional member. The continuous sectional member includes a box cross-sectional portion that provides the required supporting strength for the door frame and includes laterally extending webs that are cut and bent along edge portions as required to form intermediate spacing webs as well as connecting flanges. The modular frame structure provides a simple and economical door frame, which is lightweight, yet strong, and which allows for the convenient attachment of various other door components, for example, on the connecting flanges.
