Abstract: An adjustable electrobed includes a head which is adjustable in height and which is formed by two pieces joined together at the center of the bed. The two pieces may be pivoted about the center by an arm attached to the outer edge of each piece. The arms are moved by a motor-driven spindle to raise or lower the ends to form a "V" shape about a longitudinal axis of the bed. The bed includes a spring-mattress comprising two rigid bodies hinged near the center of the bed and adjustable by means of motor-driven arms to vary the angle between the bodies.A pneumatic mattress is superimposed on the spring-mattress and contains a cluster of slots for the arm of a patient. The elasticity of the pneumatic mattress is adjustable by changing its inflation pressure by means of a manual-pump-damper.
