Abstract

본 발명은 에어백 작동을 안전벨트의 착용시와 미착용시로 구분하여 안전벨트의 착용시에는 안전벨트의 미착용시보다 높은 충돌속도 또는 높은 충격력에서 작동되도록 2단계로 설정한 에어백 작동장치를 제공하기 위한 것으로서 이를 위해 차량 내부에 탑승자를 보호하기 위해 설치되어 차량충돌시에 급격히 팽창되는 에어백과, 상기 에어백을 작동시키는 작동회로와, 차량진행 방향의 속도변화 또는 충돌을 감지하는 충돌감지센서와, 상기 충돌감지센서로부터 감지된 신호에 의해 상기 작동회로를 가동시켜 상기 에어백을 팽창시키도록 제어하는 마이크로콘트롤러와를 포함하여 구성되는 에어백 작동장치에 있어서, 상기 마이크로콘트롤러는 승객보호용 안전벨트와 접속되어 상기 안전벨트의 착용 유무에 따라 온·오프 신호를 인가받으며 상기 안전벨트의 착용시에는 상기 마이크로콘트롤러가 안전벨트의 미착용시보다는 높은 주행속도 또는 높은 출격력을 갖는 충돌시에 상기 에어백을 작동하도록 구성되므로써 에어백의 승객의 안전을 도모하면서도 에어백의 수리비용을 절감시키게 된다.The present invention divides the airbag operation into the wearing and non-wearing of the seatbelt to provide an airbag operating apparatus set in two stages to operate at a higher impact speed or higher impact force than when the seatbelt is worn. To this end, an airbag installed to protect the occupant inside the vehicle and rapidly inflated during a vehicle crash, an operation circuit for operating the airbag, a collision detection sensor for detecting a speed change or collision in a vehicle traveling direction, and the collision An airbag operating device, comprising: a microcontroller configured to control the inflation of the airbag by operating the operation circuit by a signal sensed by a detection sensor, wherein the microcontroller is connected to a seatbelt for passenger protection and the seatbelt is connected. The on / off signal is applied depending on whether When the belt is worn, the microcontroller is configured to operate the airbag during a collision with a higher traveling speed or a higher sorting force than when the seat belt is not worn, thereby reducing the cost of repairing the airbag while improving the safety of the passenger of the airbag. .
