Abstract
A bed frame comprises a lower support structure having a head end and a foot end and a carriage arranged for translational movement on the lower support structure. An upper support structure is mounted on the carriage. The upper support structure includes a seat and an upper body support section pivotally connected thereto. A support arm is pivotally connected between the lower support structure and the upper body support section. An actuator is connected to the lower support structure. A lever arm is connected between the actuator and the carriage. Application of force from the actuator to the lever arm moves the carriage on the lower support structure while applying a lifting moment to the upper body support section. The support arm is arranged such that movement of the carriage toward the head end of the lower support structure also produces a lifting moment on the upper body support section.
