Abstract
In an air-mat apparatus, air mat has four air bags, two of which have a plurality of air-jetting holes and two others of which have no holes. In a preferred embodiment, the bags having the air-jetting holes are arranged in a zigzag pattern while the remaining two bags are arranged in a comb-shaped pattern. Air ports for the bags having air-jetting holes are connected through flowrate-adjusting valves to an air-distributing valve, while the air ports of the bags having no holes are also connected to the air-distributing valve but not through the flowrate-adjusting valves. The arrangement permits two of the air bags to be inflated and deflated to a specific degree, and the other two air bags to be inflated and deflated to a different degree.
