Abstract
An adjustable bed includes a stationary base having side rails with channels. A frame movable relative to the base has rollers which ride in these channels. An articulated deck comprising head, seat, leg and foot deck boards hingedly joined together is supported by the frame when horizontal. A plurality of links pivotally secured to brackets secured to the head and leg deck boards and pivotally secured to the base limit travel of the head and leg deck boards. Additional links pivotally secured to brackets secured to the foot deck board and to the movable frame limit movement of the foot deck board. An actuator assembly is operatively coupled to the frame and includes a linear actuator. Activation of the actuator inclines the deck boards.
