ABSTRACT:
There is provided an air bed including (a) a plurality of air chambers arranged adjacent to one another and composed of air-impermeable sheet, (b) an air pump for introducing air to said air chambers, (c) a plurality of on/off valves each of which is located between each of said air chambers and said air pump, (d) a plurality of pressure sensors each of which senses a pressure in each of said air chambers and emits a signal accordingly, and (e) a controller receiving said signal from each of said pressure sensors and controlling on/off of each of said of/off valves in accordance with said signal. In accordance with the above-mentioned air bed, since the air pump is connected to each one of the air chambers, it is possible to control an internal pressure of each of the air chambers. In addition, since air is introduced independently to each of the air chambers from the air pump, it is possible to fill each of the air chambers with air in a shorter period of time than a time required for filling all of air chambers with air in a conventional air bed in which air is introduced to one of air chambers and transferred chamber-to-chamber.
