Adjustable wheelchair

An adjustable wheelchair is disclosed which adjusts to changes in a user's size and weight which includes a scissor-type foldable mechanism which connects two side frames. Wheels for the wheelchair are attached to each of the side frames. An adjustable seat and adjustable back support are a flexible material which span from one side frame to the other. These are designed to unroll and lengthen or roll up and shorten the width of the seat and the back support between the side frames. The scissor-type foldable mechanism includes a tube which slides within a tube, a threaded rod and a threaded stop which function to allow pre-adjustment of the width of the foldable mechanism such that it may be folded and opened to the pre-adjusted width. The frames may be supplemented with reinforcements to accommodate a change in the user's weight.
