Abstract (en)
[origin: WO9835591A1] A support structure for bed bases (11), comprising a plurality of elastic slats (1), bars or strips positioned transversely to the bed frame (12) and connected to it via slat-carrying rocker joints (6), and a plurality of hydraulic jacks (2) positioned at least in a central region of the bed base (11) and connecting the rocker joints (6) to the frame (12). The hydraulic jacks (2) are connected together longitudinally to form a hydraulic circuit (3) operating on the basis of communicating vessels. By utilizing the phenomenon of pressure equalization, the pistons (15, 30) of the jacks (2) react to the pressures exerted by the body distended on the bed base (11), to compensate the hollowing created by the heavier parts of the body, i.e. those situated between the shoulder and pelvis, with an upward thrust for supporting the lighter parts, i.e. the back and kidneys.
