  • Publication number: 20020070590
    Abstract: A mobile, rotatable, electrically-wired chair having an upper section containing electrical components integrated therein for use by the chair's occupant, with electrical wires from these components internally affixed to the chair and connected by swivel connector to external communications or power lines. The swivel connector is rigidly affixed to the chair to maintain a constant connection between internal and external electrical wires while at the same time allowing stable positioning of the external wires relative to the chair. The rotational movement of the rotating portion of the chair is transferred to the internal, rigidly affixed wires, then absorbed by the swivel connector, thus allowing chair rotation without tangling, gnarling, and stretching of either the internal or external electrical wires.
