Abstract

An automotive vehicle has a door adapted to pivot about a generally horizontal pivot axis, with the door including a shell defining a space surrounded by the shell. The door is pivoted upon bearings located at each end of the door. A full floating torsion bar is provided and includes a first end rotationally grounded to the door shell and a second end engaged with and rotationally locked with a bearing inserts so that the torsion bar will be subjected to torsional loading as the door is pivoted. At least a portion of the torsion bar extends along an external recess defined by the door's inner and outer panels.
