PROBLEM TO BE SOLVED: To provide a seat belt attachment/detachment detection device which can continuously transmit an attachment/detachment detection signal and secure reliability.SOLUTION: A seat belt attachment/detachment detection device 100 includes: a tongue part 10 which is supported by a seat belt; a buckle part 20 which holds the tongue part 10 in an inserted state to make the seat belt a fitting state; a fitting detection part 11 which detects the insertion-holding state between the tongue part 10 and the buckle part 20; a seat belt side communication part 12 which transmits the detection result of the fitting detection part 11 with a radio signal; a control part 13 which determines the fitting state on the basis of the detection result and controls the seat belt side communication part 12; power supply means which supplies power to the seat belt side communication part 12; and a vehicle side device 30 which performs radio communication with the seat belt side communication part 12 and receives the detection result. The power supply means includes a power supply part 31 for supplying power, a power storage part 14, and a charging part 15. The power supply part 31 supplies power to the charging part 15 in a case where the seat belt is in the storage state to charge the power storage part 14.
【課題】継続的に着脱検知信号を送信可能で信頼性を確保することができるシートベルト着脱検知装置を提供する。【解決手段】シートベルト着脱検知装置100は、シートベルトに支持されたタング部10と、タング部10を挿入保持してシートベルトを装着状態とするバックル部20と、タング部10とバックル部20との挿入保持状態を検知する装着検知部11と、装着検知部11の検知結果を無線信号で送信するシートベルト側通信部12と、検知結果に基づいて装着状態を判別しシートベルト側通信部12を制御する制御部13と、シートベルト側通信部12に電力を供給する給電手段と、シートベルト側通信部12と無線通信を行い、検知結果を受信する車両側装置30と、を備え、給電手段は、電力を供給する給電部31と、蓄電部14と、充電部15と、を備え、給電部31はシートベルトが収納状態の場合に充電部15に電力を供給し、蓄電部14を充電する。【選択図】図1
