ABSTRACT:
A patient support apparatus has a stationary lower part and a displaceable upper part carrying a patient. The upper part has a guide surface which is curved in sectional plane, and the lower part has a guide surface matched to this curve. Outlet nozzles for air are provided in the guide surface of the lower part so that an air gap and an air cushion are produced between the guide surface of the lower part and the upper part by means of an air flow. The upper part, with a patient thereon, can be displaced in a longitudinal direction, perpendicular to the sectional plane, by riding on the air cushion.
