Abstract
This paper deals with a new bed for human body, called a multi-point press bed by air control. Air-cells and rubber-tubes are located lengthwise and sideways respectively, and pins are located on a point of the intersection of air-cells and rubber tubes. When pressures of the air-cells and rubber-tubes increase, the pins are moved up and balls on the pins push up the back of a human body. It is able to change the magnitude of the pressure to the back and the pressure distribution by controlling the pressure of the air-cells and rubber-tubes. This bed is useful for the prevention of bedsore or for the relaxation.
