PROBLEM TO BE SOLVED: To provide a technique for further accurately acquiring persons condition.SOLUTION: This biological signal detection mechanism is provided as a tension structure, with its stretched across a back support section of a human body support mechanism, and further, has a three-layered structure including: a back-supporting cushion member 201 a base cushion member 220, both the members being integrated by a bag-like member 210 and a sensing mechanism section 230 disposed between the back-supporting cushion member 201 and the base cushion member 220. A pelvic/lumbar support member 240 for energizing a pelvic/lumbar support area of the back-supporting cushion member 201 is provided below the sensing mechanism section 230. The sensing mechanism section 230 is disposed between the back-supporting cushion member 201 and the base cushion member 220, so that tension in the plane direction is generated in each cushion member. The biological signal detecting mechanism is stretched across the back support section of the human body support mechanism, whereby the sensing mechanism section 230 disposed on the backside of the back-supporting cushion member 201 can detect biological signals with high sensitivity.COPYRIGHT: (C)2013,JPO&INPIT【課題】人の状態をより正確に把握する技術を提供する。【解決手段】人体支持機構の背部支持部に張って張力構造体として設けられる背部支持用クッション部材201とベースクッション部材220とが袋状部材210により一体化され、さらに、背部支持用クッション部材201とベースクッション部材220との間に配置されるセンシング機構部230を備えた3層構造である。センシング機構部230の下方には、背部支持用クッション部材201の骨盤・腰部支持領域を付勢する骨盤・腰部支持部材240を有する。背部支持用クッション部材201とベースクッション部材220との間にセンシング機構部230が配置されるため、各クッション部材には面方向に張力が生じる。これを人体支持機構の背部支持部に張って設けられることにより、背部支持用クッション部材201の裏側に配置されるセンシング機構部230は、生体信号を感度高く検出できる。【選択図】 図4
