ABSTRACT:
A wheelchair incorporates a tilt mechanism with a center of gravity compensation by employing a rotary actuator. The actuator is secured to the underside of the seat and has an arm pivotally secured to the frame. A seat pivot axis is located on a movable member that allows the axis to shift from a rear portion of the wheelchair toward a front portion as the seat is tilted from its upright position to a tilted position. This assures that the center of gravity of the user is maintained within the wheelbase of the chair, i.e., compensates for center of gravity.
