Claims (7)

  1. 자동차용 팽창 가능한 억제 시스템의 점화 수단(10)을 활성화 하기 위한 회로에 있어서, 자동차 스토리지 배터리(18), 스토리지 커패시터(24), 상기 커패시터에 연결되며 배터리의 전압보다 큰 전압으로 커패시터를 충전할때 적용되는 파워 서플라이(28), 상기 파워 서플라이에 배터리를 연결하기 위해 오프(OFF) 위치에서 온(ON) 위치로 동작하는 점화스위치, 자동차 충격시 노멀상태(normal state)에서 점화 상태로 작동가능한 충격 센서수단(12, 14, 16), 상기 점화 수단과는 직렬로 배터리 및 커패시터와는 병렬로 상기 충격센서 수단을 연결하기 위한 수단(22, 26), 상기 점화수단에 인가되는 전압을 감시하기 위한 처리수단(50), 및 점화 스위치의 폐쇄(closure) 이후 예정된 대기 식간에 파워 서플라이를 동작하기 위한 시간지연 수단(60)을 포함하는 자동차용 팽창가능한 억제 장치의 점화회로.
  2. 제 1 항에 있어서, 상기 예정된 대기시간은 점화스위치가 폐쇄된 직후 점화수단에서 프로세서에 의해 감시되는 전압이 커패시터 보다는 상기 배터리에서 확실히 생겨나도록, 프로세서가 진단절차를 완료하는데 필요한 시간보다 큼을 특징으로 하는 점화회로.
  3. 2 항에 있어서, 상기 프로세서에 의해 감시되는 전압은 점화수단에 의해 출력된 저수준 신호임을 특징으로 하는 점화회로.
  4. 1항 내지 3항중 어느항에 있어서, 상기 충력 센서 수단은 상기 점화수단(10)의 일단에 연결된 아밍센서(arming sensor)(12) 및 점화수단(10)의 타단에 연결된 식별센서(14, 16)을 포함함을 특징으로 하는 점화회로.
  5. 1항 내지 4항중 어느 항에 있어서, 나아가 상기 압력센서수단에 연결된 출력, 상기 카패시터(24)에 연결된 제 1 입력 및 점화스위치(20)을 지나 자동차 바테리(18)에 연결된 제 2 입력을 갖는 논리 OR 회로를 포함함을 특징으로 하는 점화회로.
  6. 1항 내지 5항중 어느 항에 있어서, 상기 파워서플라이는 커패시티를 36V로 충전시키게 되어 있음을 특징으로 하는 점화회로.
  7. 1항 내지 6항중 어느항에 있어서, 상기 파워스플라이(28)은 조정 파워서플라임을 특징으로 하는 점화회로.
