Abstract
A folding wheelchair frame including a compound folding mechanism having fore and aft tubular hinged wing frames pivotally coupled to the chair's side frames and to a longitudinal tubular slide-follower coordinating assembly. Scissored arms coupled between the forward hinged frame and slide-follower coordinate the folding action relative to the chair's longitudinal center axis and allows the latching thereof. Associated swing-away footrests, removable armrests and latched, folding back frames further reduce the folded profile and facilitate chair usage.
