To provide a seating state determination device which can determine a state of a crewman without requirement for a complicated mounting work.SOLUTION: A seating state determination device comprises a measurement result acquisition means 1, a change amount calculation means 2, and a determination means 3. The measurement result acquisition means 1 acquires data concerning a distance to an object existing in a direction parallel to a webbing, which is measured by a sensor, from the sensor which measures said distance in a shoulder anchor from which the webbing of a seat belt is pulled out at a wearing time. The change amount calculation means 2 calculates an amount of change in a length of the webbing, which has been pulled out based on acquired data concerning the distance from the shoulder anchor to the object. The determination means 3 determines a state of a crewman who wears the seat belt based on the amount of change in the length of the pulled-out webbing.SELECTED DRAWING: Figure 1

    【課題】複雑な取り付け作業を必要とすることなく、乗員の状態を判断することができる着座状態判別装置を提供する。【解決手段】着座状態判別装置を、計測結果取得手段1と、変化量算出手段2と、判断手段3を備える構成とする。計測結果取得手段1は、シートベルトのウェビングが装着時に引き出されるショルダーアンカーにおいて、ウェビングに平行な方向に存在する物体までの距離を計測するセンサから、センサが計測した前記距離のデータを取得する。変化量算出手段2は、取得したショルダーアンカーから物体までの距離のデータを基に引き出されているウェビングの長さの変化量を算出する。判断手段3は、引き出されているウェビングの長さの変化量を基にシートベルトを装着した乗員の状態を判断する。【選択図】 図1
