A height adjustable bed frameworkincludes a base frame, an elevatable frame, a lift chainand a power module. The lift chain is connected to the base frame or the elevatable frame and the power module is connected to the other frame. The power module includes an energy converter such as an electric motor, a planetary gear traindriven by the energy converter and a chain driver, such as a sprocket, engaged with the lift chain and driven by the planetary gear train.

A brake system for a patient support apparatus having a base frame includes pedals positioned to be moved by a user to move a brake and a mechanism positioned to coordinate movement of the pedals so that downward movement of one pedal positioned adjacent the head end of the base causes movement of the mechanism in a first direction and downward movement of another of the pedals causes movement of the mechanism in a second direction, opposite the first direction.

A bed includes a base framehaving a head end and a foot end, an elevatable framealso having a head end and a foot end, a lift assemblyorcomprising an actuation system connected to one of the frames, a push chainhaving an actuator enddriven by a lead screwand a distal endconnected to the other of the frames. Rotary motion of the lead screw changes elevation of the elevating frame relative to the base frame.
