< Topic >In the body region of the user of rank giving stimulus to vertical direction with pinpoint, while solving the tension of the body, it offers the stretch auxiliary equipment which can stretch effectively.SolutionsIn the body backing 2 which supports the body of the user of rank and body support internal the supply and exhaust device it consists of with the supply and exhaust hose 5 which connects with 4 which the air supply and exhaust is done and the supply and exhaust device and the air bag in the plural air bags 3 which common facilities are done and the air bag. When the surface where it touches with the body of the user of the body backing, is formed with rally plastic material low, the air bag, the plural sack bodies which are connected to vertical direction vis-a-vis the surface of the body backing husband is formed by the multilayer structure which is penetrated in the connected section, the air is supplied from the supply and exhaust device, it expands to vertical direction, pushes up the body region of the user.< Selective figure >Figure 1【課題】臥位の使用者の身体部位にピンポイントで垂直方向に刺激を与えて身体の緊張を解きながら効果的なストレッチを行うことのできるストレッチ補助装置を提供する。【解決手段】臥位の使用者の身体を支持する身体支持体2と、身体支持体内に並設された複数のエアバッグ3と、エアバッグに空気を給排気する給排気装置4と、給排気装置とエアバッグとを接続する給排気ホース5とからなる。身体支持体の使用者の身体と接する上面が、低反発合成樹脂素材で形成され、エアバッグが、身体支持体の上面に対して垂直方向に連結された複数の袋体が連結部で夫々貫通した多層構造に形成され、給排気装置から空気が供給されると垂直方向に膨張し、使用者の身体部位を押し上げる。【選択図】図1
