Abstract
A foldable wheelchair having a folding mechanism connecting two side frame assemblies to each other. The side frame assembly supports a castor frame piece, pivoting shafts of the folding mechanism, drive wheel axles and a seat back tube. The side frame assemblies are made of two halves that are secured together and may be fabricated from compression or injection molded composite plastics. The seat angle is adjusted by pivoting the side frame assemblies around a pivot point located in an upward and forward region of the side frame assembly.
