To provide a seat occupation situation detector applicable even to a seat whose direction can be changed by 180 degrees.SOLUTION: A seat occupation situation detector 5 comprises: a distance measuring sensor 6 that is disposed on an arm rest 4a of a seat 1 and detects existence of an object on a seat part 2; a micro switch 7 that is disposed at a backrest 3 and detects the backrest 3 being pressed; and a determination unit 8 that on the basis of a detection result of the distance measuring sensor 6 and a detection result of the micro switch 7, determines whether the seat 1 is vacant, is occupied by a person, or is occupied by placed baggage. When an immediately previous state of the seat is a vacant state, the determination unit 8 determines that the seat 1 is occupied by a person in the case that an object exists on the seat part 2 and the backrest 3 is pressed, determines that the seat 1 is occupied by placed baggage in the case that an object exists on the seat part 2 and the backrest 3 is not pressed, and determines that the seat 1 is vacant in the case that no object exists on the seat part 2.SELECTED DRAWING: Figure 1

    【課題】向きを180度変えられる座席にも適用可能な座席占有状況検知装置を提供する。【解決手段】座席占有状況検知装置5は、座席1の肘掛け4aに配置され、座部2上に物体があることを検知する測距センサ6と、背凭れ3に配置され、当該背凭れ3が押圧されていることを検知するマイクロスイッチ7と、測距センサ6の検知結果とマイクロスイッチ7の検知結果とに基いて、座席1が空席か、人が着座しているか、又は荷物が置かれているかを判定する判定部8と、を備えている。判定部8は、直前状態が空席である場合に、座部2上に物体があり背凭れ3が押圧されている場合は座席1に人が着座していると判定し、座部2上に物体があり背凭れ3が押圧されていない場合は座席1に荷物が置かれていると判定し、座部2上に物体がない場合は座席1が空席であると判定する。【選択図】図1
