PROBLEM TO BE SOLVED: To provide a control method for an air mat giving a user a comfortable feeling by giving alternate expansion/contraction with fine wave motion and having an air cell internal pressure non-affected by the body weight, body position or physique of a user and the air mat having the same.SOLUTION: This control method of the air mat, which is formed by aligning a plurality of bag-shaped air cells, dividing them into a plurality of systems and communicating them with each other, controls the air supply and exhaust to alternately repeat the expansion and contraction at a predetermined period for every system and communicating the inside of the air cells of an air cell system changed into a contraction state, with atmosphere for a predetermined time to exhaust the inside air and lower the internal pressure, after that cutting off the communication state with the atmosphere, supplying air to the inside of the air cell, and retaining a preset predetermined internal pressure lower than the internal pressure of the air cell in the expanded state.COPYRIGHT: (C)2009,JPO&INPIT【課題】交互膨縮が微波動となり、利用者に快適感を与え、かつ利用者の体重、体位、体型等に影響されないエアセル内圧となるエアマットの制御方法及びそれを備えたエアマットを提供することにある。【解決手段】袋状のエアセルを複数本並設し、前記エアセルを複数の系統に分けてそれぞれ連通するとともに、各系統ごとに交互に所定の周期で膨張・収縮を繰り返すようにエアの供給・排気を制御するエアマットの制御方法において、前記収縮状態に切り替わったエアセル系統のエアセル内を所定時間大気と連通状態におき内部のエアを排気させて内圧を下げ、その後大気との連通状態を絶ち、エアセル内にエアを供給して、膨張した状態にあるエアセルの内圧よりも低い予め設定した所定内圧に保持するようにした。【選択図】図1
