摘要：
An articulating bed incorporates a support frame with a head end rail, a foot end rail and having side frame rails. An upper body support frame is rotatably connected to a first cross member in the frame. An elevating assembly for the upper body support frame has two angled arms attached to the first cross member with hinges. A first pair of wheels is attached to the angled arms at a vertex and a second pair of wheels attached at an end of the arms distal from the hinges. A first actuator is attached from the head end rail to a cross brace extending between the angled arms. The elevating assembly has a first range of motion in which the first pair of wheels are in contact with longitudinal rails in the upper body support and a second range of motion in which the second pair of wheels are in contact with the longitudinal rails.
