A lift mechanism (40) for a wheelchair (10) includes a parallelogram linkage (46) and an actuator (60) for moving the linkage between a retracted position and an extended position to raise and lower a chair (30). One link (50) of the linkage is slidingly engaged with a rail member (48). Movement of the linkage is constrained by another link (58) such that as the chair is raised and lowered, the longitudinal position of an occupant's center of gravity relative to the wheelchair frame (12) is substantially maintained. The lift mechanism may be combined with a tilt actuator (92) to allow rotation of the chair. A chair tilt mechanism (70) is also provided having a tilt actuator (84), a first link (78) slidingly engaged with a rail member (76) and a second link (82) constraining movement of the first link. The tilt mechanism is capable of tilting the chair while substantially maintaining the longitudinal position of the occupant's center of gravity.
