A furniture member having a tilt position mechanism (47) includes a base frame (12) positioned on a floor surface. A first operating mechanism is connected to the base frame (12) defining a tilt mechanism. The tilt mechanism (47) includes a tilt motor (30) connected to a rear member of the base frame. A torque tube (118, 120) positioned forward of the tilt motor is displaced by operation of the tilt motor. First and second rotation links (84, 112) are rotatably connected to the base frame and fixed to the torque tube (118, 120). A pivot tube (22) is positioned rearward of the torque tube and connected by first and second journal links (68, 70) to the support frame. The journal links are shorter than the rotation links such that torque tube forward and upward displacement forwardly rotates the journal links and displaces the pivot tube, creating a furniture member rear tilt position having the torque tube elevated above the pivot tube. |
