Adjustable bed having four linear actuators

摘要

An adjustable bed includes a stationary seat deck board and independently movable front and rear carriages powered by linear actuators supported by a stationary base. A head deck board is hingedly secured to the front carriage and moves with it. Leg and foot deck boards hingedly joined together are supported by the rear carriage and move with it. Additional linear actuators move the head deck board and leg deck boards between horizontal and inclined positions independently.
