Abstract
A powered movable chair controllable by a user. The chair includes a frame, a powered apparatus mounted to the frame to power the movable chair, and a controller including a control circuit coupled to the powered apparatus. The control circuit includes at least two switches for selectively controlling a change of the status of the powered apparatus between a locked state and an unlocked state. The control circuit is operable to generate an output signal allowing control of the powered apparatus in the unlocked state and preventing control of the powered apparatus in the locked state. The control circuit is further operable to change from the unlocked state to the locked state when a user operates a first switch of the at least two switches, and to change from the locked state to the unlocked state when a user operates a second switches of the at least two switches for a predefined time period.
