Abstract
A wheelchair frame has a guide member operatively and slidably connected thereto. A chair is pivotally attached to the slidable guide member. An actuator for moving the chair forward and backward is 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 the frame and the other end pivotally connected to the seat of the integral wheelchair. Upon actuation of the actuator, the guide member moves the chair forward or backwards and as a consequence thereof, the seat is tilted backward or forward by the link arm to substantially maintain the center of gravity of a person seated in the chair.
