Abstract: A frame for a collapsible wheel chair which permits custom tailoring of the chair to the size of the invalid with only minor modifications. The frame includes telescoping front posts which support horizontally extending arms to which a flexible seat is secured. A pair of cross struts are provided which are rotatably secured to the horizontally extending arms and to the bottom struts of the frame. When the chair is collapsed by bringing the two sides of the chair frame together, the telescoping post permits the horizontal arms to raise a distance determined by the length of the cross struts. Thus, during manufacture, the only parts that need be custom made to accommodate differing sized invalids is the length of the cross struts.
