Abstract
A wheelchair has a constant center of gravity tilt assembly which can be connected to any type of frame structure. A chair is pivotally attached to the tilt assembly which includes a slidable guide member. The guide member is slidably attached to a guide rail which can be mounted on the frame. An actuator for moving the chair forward and backward is operatively connected at one end to the slidable guide member and at the other end to the wheelchair frame. A link arm has one end operatively connected to said frame and the other end pivotally connected to the seat of the integral chair. Upon actuation of the actuator, said guide member moves said chair forward or backwards and as a consequence thereof, said seat is tilted backward or forward by said link arm to substantially maintain the center of gravity of a person seated in the chair.
