Abstract
A wheelchair with two facing, interconnected, adjustable sideframes having fit thereto a seat, backrest, driving wheels and guide wheels is described. The wheelchair is characterized in that each sideframe has two rigid frame parts, which are adjustably interconnected in the longitudinal direction of the wheelchair by elongated frame sections. On one rigid frame part of each sideframe can be fit one of the driving wheels and on the other rigid frame part of each sideframe one of the guide wheels. The wheelchair frame is readily longitudinally adjustable. Simultaneously with the adjustment of the seat position, there is an adjustment of the wheels so that an optimum weight distribution over the wheelchair wheels is maintained. The frame has an extremely high rigidity.
