Abstract
A method of operating a wheelchair during an un-recline process involves a wheelchair having tilt and recline functions, the wheelchair including a seat frame, a tilt actuator for tilting the seat frame, a back frame, a recline actuator for reclining the back frame. A sensor for determining the angle of recline is provided. A controller for controlling the tilt actuator and recline actuator is also provided. The controller is provided with a plurality of preprogrammed sequences for moving the seat frame and the back frame during an unrecline procedure. The sequences include tilting the seat frame as an initial part of the unrecline sequence, wherein the sequences are a function of the initial angle of recline at the initiation of the recline sequence. An initial angle of recline at the initiation of a recline sequence is determined, and the back frame is unreclined according to one of the preprogrammed sequences in response to the determined initial angle of recline.
