Abstract
A wheelchair is provided, having a recline mechanism for the chair back and wherein the seat is repositioned forward in response to recline to reposition the user's weight relative to the supporting wheels. The chair is also independently equipped with a weight-shifting tilt mechanism. Moreover, a bilateral tracking mechanism (i.e., controlled motion is transmitted to both sides) is used to reposition the seat. This avoids torque due to uneven loading of the chair. Back canes of the chair and/or brackets on the chair back are slotted to enable infinite adjustment of chair arms, ventilator trays, and other accessories.
