A breakaway bi-folding door assembly, which would include at least a pair of bi-folding doors of the type wherein a first end of one door panel is hinged to a door frame, and a second end of a second door panel travels within a slot in the frame to allow the door panel to fold and unfold between open and closed positions for defining an open or closed doorway through a passage. Further there is provided a pivoting frame member positioned above the second door panel, and hinged to the second door at a first end and attached to the second door at a second end, so that at any point along its travel, the attaching means could be overcome by force and the second end of the second door panel can swing freely of the pivoting frame member. Upon the pivoting frame member sliding within the slot, the second door would return to its attached position automatically to form the bi-folding door configuration.
