PROBLEM TO BE SOLVED: To provide a buckle capable of suppressing increase a number of wirings required for sending a determination result on a buckle side to outside of the buckle.SOLUTION: A buckle comprises: a connection part which can be connected to a tongue which is attached to a seat belt of a vehicle; a buckle switch for detecting connection of the tongue and the connection part; a connection determination part for determining presence/absence of connection on the basis of the detection result of the buckle switch; an object detection part for detecting an object on a seat of the vehicle by transmission and reception of an electromagnetic wave; a presence determination part for determining presence/absence of a passenger on the seat on the basis of the detection result of the object detection part; a pair of power source terminals to which a DC power source voltage is applied through a pair of power lines; and an information sending part for, changing a current value of a current flowing to the power source terminals, for sending first determination information which contains the determination results of the connection determination part and of the presence determination part to outside of the power source terminals by using the power lines.SELECTED DRAWING: Figure 1
【課題】バックル側で判定した結果をバックルの外部に送信するために必要な配線数が増加することを抑制できる、バックル。【解決手段】車両のシートベルトに取り付けられるタングと連結可能な連結部と、前記タングと前記連結部との連結を検知するバックルスイッチと、前記バックルスイッチの検知結果に基づいて前記連結の有無を判定する連結判定部と、前記車両のシート上の物体を電磁波の送受により検知する物体検知部と、前記物体検知部の検知結果に基づいて前記シート上の乗員の存否を判定する存否判定部と、直流の電源電圧が一対の電力線を介して印加される一対の電源端子と、前記電源端子に流れる電流の電流値を変更することによって、前記連結判定部の判定結果と前記存否判定部の判定結果とを含む第1の判定情報を前記電源端子の外部に前記電力線を用いて送信する情報送信部とを備える、バックル。【選択図】図1
