ABSTRACT:
A wheelchair having a turntable rotatably mounted on one footrest thereof. The turntable is operatively connected to the mounting fork of a steering caster by means of an extended link and a lever bar whereby rotational movement of the turntable by the foot of the chair occupant will cause a change in the direction of movement of the chair. An adjustable stop means is arranged to act against the link to prevent the chair from moving into an uncontrollable position and further acts to prevent the mechanism from unduly twisting the occupant's leg in the event the steering caster strikes an obstruction or the like.
