Abstract: A device for tilting the top end and/or bottom end of a bed, includes two hingedly connected frames and a control unit operably connected thereto for adjusting the spacing therebetween. One fixed frame is supported on the bed base while the other, movable frame supports one end of a mattress. The fixed frame comprises two parallel co-planar tubes and the movable frame consists of a U-shaped frame pivotably mounted on and between the tubes. The control unit is attached to the fixed frame and controls the longitudinal translation of slide blocks with worm screws. The blocks are slidable along the tubes to tilt the movable frame relative to the fixed frame. The worm screws are mounted in the two tubes and the control unit is located outside the area encompassed by the fixed frame.
