Abstract
A lift mechanism a power wheelchair includes linear actuators on opposing sides of the chair that provide a space into which a tilt mechanism can nest when the lift mechanism is in its retracted position. The linear actuators perform both the function of operating the lift mechanism and structurally supporting at least a part of the lift mechanism. The lift mechanism and tilt mechanism are each self-contained modules that can be optionally installed into the power wheelchair.
