<p>The invention relates to a collapsible wheelchair comprising a frame comprising: a first side frame; a second side frame substantially the same as the first side frame; coupling means holding the two said side frames at least in the operative situation in the same positions at a mutual distance. The invention provides a wheelchair which has the feature that each side frame comprises: a first middle sub-frame, a front sub-frame, a rear sub-frame; the front and rear sub-frames are pivotable relative to the first middle sub-frame by means of a hinge joint; the coupling means are embodied as spacers holding corresponding sub-frames at fixed mutual distance; a second middle sub-frame is arranged between the front and rear sub-frame for pivoting relative to both these sub-frames by means of a hinge joint such that each side frame, and therefore the whole frame, can be folded round horizontal pivot axes until the three sub-frames lie at least substantially on top of each other; and stop means are present between a middle sub-frame and at least one of the other sub-frames which determine a stable operating position of the wheelchair.</p> |
