  "abstract": "The sick-bed is comprised of a bedstead and a bed frame as the mattress support, mounted cardanically on same for the decubitus prophylaxis, which bed frame can be precessed by means of a drive unit. The bed frame is cardanically suspended on at least three, in particular four lifting drives, which are separate from each other and continuously height-adjustable. Said lifting drives are controllable in such a manner that the central normal of the bed frame running through the gravity center of the bed frame is allowed to carry out a continuous, damped and slow precession movement.",
  "claims": [
    "1. A sick-bed comprised of a bedstead and, for the decubitus prophylaxis, a bed frame as the mattress support, mounted cardanically on said bedstead, which bed frame per se is dimensionally rigid and can be precessed by a drive unit, characterized by a mounting of the bed frame (2) on at least three continuously height-adjustable lifting drives (5) which are separate from each other. 2. The sick-bed according to claim 1, characterized by a mounting of the bed frame (2) on four lifting drives (5), one of each being in each case articulated to one of the four corners each of a rectangular bed frame (2) in each case via a cardan joint (6). 3. The sick-bed according to any one of claims 1 or 2, characterized by a vertical fixation of the lifting drives (5) on the bedstead (1). 4. The sick-bed according to any one of claims 1 through 3, characterized by a group drivability of the lifting drives (5) in such a manner that the bed frame (2) optionally is mounted continuously precessable or is stationarily height-adjustable or inclination-adjustable. 5. The sick-bed according to any one of claims 1 through 4, characterized by a lifting drive (5) which can be acted upon electromotively. 6. The sick-bed according to claim 5, characterized by an electromotively settable telescopic lifting column as the lifting drive (5). 7. The sick-bed according to any one of claims 1 through 4, characterized by a hydraulic working cylinder as the lifting drive (5). 8. The sick-bed according to claim 7, characterized by a configuration of the hydraulic working cylinders (5) as an in each case integrated constructional unit having a compressor and a control valve. 9. The sick-bed according to any one of claims 7 or 8, characterized by compressors of the working cylinders (5), which compressors are electronically drivable and which can be electrically acted upon. 10. The sick-bed according to any one of claims 7 through 9, characterized by a central hydraulic multiple valve for the selective setting of the hydraulic working cylinders (5), and a connection of said multiple valve to a central compressor or a central hydraulic pressure supply line. 11. The sick-bed according to any one of claims 1 through 10, characterized by a bed frame (2), which, independent of the bedstead (1), can be transferred onto a secondary undercarriage."
