摘要： A furniture member powered mechanism providing both lift and zero gravity operating positions includes a first torque tube having first and second connecting links fixed thereto. The connecting links are each rotatably connected to a first or second connecting arm. The first and second connecting arms are rotatably connected to a gear housing. A positioning motor connected to the gear housing displaces a slide member coupled to the gear housing. Slide member motion displaces the first and second connecting arms, displacing and rotating the first torque tube. First and second connecting plates are rotatably connected to the slide member. A second torque tube is fixed at opposite ends to each of first and second arm rest portions of a furniture member base portion. The first and second connecting plates are also connected to the second torque tube such that slide member displacement rotates the base member.
