Abstract
A furniture member mechanism includes a base frame. A first mechanism connected to the base frame includes a first motor connected to the base frame. A torque tube is connected to the first motor and is displaced by operation of the first motor. First and second rotation links are individually rotatably connected to the base frame and are connected to the torque tube. The first and second rotation links provide for rotation of the second mechanism to one of a rear tilt position or a forward lift position by operating the first motor displacing the torque tube.

16. A furniture member mechanism providing rearward tilt and forward lift operations, comprising:
-
a base frame supporting the furniture member on a floor surface; a first mechanism connected to the base frame including; a first motor movably connected to the base frame; a torque tube connected to an extension tube displaced by operation of the first motor; and a pivot tube connected to the first mechanism and connected by first and second journal bearings to the base frame; a second mechanism supported and rotated by the first mechanism, the second mechanism having a second motor; and first and second rotation links individually rotatably connected to the base frame and connected to the torque tube, the first and second rotation links providing for rotation of the second mechanism to one of a rear tilt position having the pivot tube positioned below the torque tube and a forward lift position having the pivot tube positioned above the torque tube by operation of the first motor displacing the torque tube. - View Dependent Claims (17, 18, 19, 20)
