PROBLEM TO BE SOLVED: To provide a seat and a wheelchair that have high accuracy in detecting body pressure distribution of a seated person, that discriminate posture of the seated person based on the body pressure distribution, and that give an alarm in accordance with the discrimination result of the posture.SOLUTION: The seat 93 includes a body pressure sensor unit 10 and an alarm device 48. The body pressure sensor unit 10 includes a body pressure sensor 5 and a control part 4. The body pressure sensor 5 includes a thin film 51 for the body pressure sensor, electrodes 01X-16X, 01Y-16Y for body pressure, and detection parts A0101-A1616 for body pressure. The body pressure sensor 5 can detect the body pressure of a seated person M as quantity of electricity. The control part 4 calculates the body pressure distribution of the seated person M based on the quantity of electricity and discriminates the posture of the seated person M based on the body pressure distribution.COPYRIGHT: (C)2012,JPO&INPIT【課題】着座者の体圧分布の検出精度が高く、当該体圧分布を基に着座者の姿勢を判別可能であり、姿勢の判別結果に応じて警報を発生可能なシートおよび車椅子を提供することを課題とする。【解決手段】シート93は、体圧センサユニット10と警報装置48とを備える。体圧センサユニット10は、体圧センサ5と制御部4とを備える。体圧センサ5は、体圧用センサ薄膜51と体圧用電極01X~16X、01Y~16Yと体圧用検出部A0101~A1616とを有する。体圧センサ5は、着座者Mの体圧を電気量として検出可能である。制御部4は、当該電気量から着座者Mの体圧分布を演算し、体圧分布から着座者Mの姿勢を判別する。【選択図】図4
