본 발명은 에어백장치에 관한 것으로, 보다 상세하게는 차량의 뒷좌석에 탄 승객을 충돌로부터 보호하도록 된 후방 승객 보호용 에어백장치에 관한 것이다.The present invention relates to an airbag device, and more particularly to a rear passenger protection airbag device for protecting a passenger in a rear seat of a vehicle from collision.

일반적으로 에어백은 핸들의 중심부나 인스트루먼트 패널등에 설치되어 자동차 운행중 급작스런 충돌사고시 운전자나 승객을 보호하기 위한 수단으로써, 차량 충돌에 의해 소정치 이상의 압력을 받으면 충격감지센서에서 이를 감지하여 인플레이터를 통하여 순간적으로 가스를 에어백 속으로 폭발시킴으로써 에어백이 팽창되어 운전자를 보호에 주도록 하고 있다.In general, the airbag is installed in the center of the handle or the instrument panel to protect the driver or passenger during a sudden crash while driving the vehicle.When the airbag receives a pressure higher than a predetermined value due to a vehicle crash, the shock sensor detects it and instantaneously through the inflator. By exploding the gas into the airbag, the airbag is inflated to protect the driver.

이와 같은 에어백 종류로는 화약을 폭발시켜서 폭발된 가스로 에어백을 급속히 부풀려서 운전자의 안전을 보호해주는 폭발식 에어백과, 가스실린더에 압축가스를 압축된 상태로 주입시켜 두었다가 충돌시 가스를 분사시켜 에어백을 충진시키도록하는 압축시 에어백 방식이 있으며 그외에도 여러 가지 방식의 에어백이 개발되고 있으나 주로 폭발식 에어백이 많이 사용되고 있다. These types of airbags include explosive airbags that explode gunpowder and inflate the airbags rapidly to protect the driver's safety, and inject compressed gas into the gas cylinders in a compressed state and inject the gas in the event of a crash. There is an airbag method for compressing the filling, and various airbags have been developed, but mainly explosive airbags are used.

이와 같은 이러한 에어백 설치는 운전석과 조수석의 승차자를 위하여 설치는 되어 있지만 뒷좌석 중앙에 승차한 승객을 위한 에어백은 없는데, 이는 앞좌석에 탑승한 승객은 차량 충돌시 직접적으로 충격을 받는데 반해 벤치형식의 뒷좌석에 탑승한 승객은 차량 충돌을 간접적으로 전달받으면서 또한 차량 충돌에 대한 순간적인 대처 상황이 보다 자유로워 안전 벨트만으로도 대처 할 수 있기 때문이다.These airbags are installed for the driver and front passenger, but there are no airbags for passengers in the center of the rear seats, whereas passengers in the front seats are directly impacted in the event of a vehicle crash, whereas bench-type rear seats Passengers on board can be indirectly informed of vehicle collisions and have more freedom to deal with vehicle collisions in an instant.

그러나, 뒷좌석에 앉은 승객을 보호하기 위한 안전수단으로써 안전벨트만이 설치되어 있으면, 차량 충돌 시 만약 안전벨트를 착용하지 않았을 시에는 앞좌석이 설치된 빈 공간 사이로 튕겨 나가거나 콘솔박스 등에 부딪치는 위험이 있고 이는, 뒷좌석의 승객만의 부상이 아니라 앞좌석 운전자나 승객에게도 심각한 상황을 초래할 수 있는 위험성이 내포되어 있게 된다.However, if only the seatbelt is installed as a safety measure to protect the passengers sitting in the rear seats, there is a risk that the vehicle will bounce between empty spaces where the front seats are installed or hit the console box if the seatbelt is not worn. This is not only injuries of the passengers in the rear seats, but also risks that can cause serious situations for the front seat drivers or passengers.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 차량 충돌 시 앞좌석 사이의 공간부위를 에어백으로 막아 뒷좌석 승객의 앞좌석 쪽으로의 이동을 구속시켜 뒷좌석 승객의 부상은 물론 앞좌석 승객에 대한 안정성을 동시에 확보함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and in the event of a vehicle collision, the space between the front seats is prevented with an airbag to restrict the movement of the rear seat passenger toward the front seat so that the rear seat passenger may be injured as well as the front seat passenger. Its purpose is to secure stability at the same time.

상기와 같은 목적을 달성하기 위한 본 발명은, 후방 승객 보호용 에어백 장치가 차량의 충돌 시 센서 신호를 받는 ACU를 통한 제어 신호에 따라 가스를 발생시키는 인플레이터에 의해 팽창되는 에어백 쿠션을 구비한 에어백 모듈과, In order to achieve the above object, the present invention provides an airbag module having an airbag cushion in which the rear passenger protective airbag device is inflated by an inflator that generates gas in accordance with a control signal through an ACU receiving a sensor signal when a vehicle crashes; ,

이하 본 발명의 작동을 첨부된 도면을 참조로 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 차량의 충돌 시 이를 감지하는 센서의 신호를 입력 받은 ACU가 발생하는 제어신호에 따라, 전방 시트(S)의 뒤에서 플로우(F)로부터 에어백 모듈(2)의 에어백 쿠션(4)이 전개되어져 후방 승객(P)을 보호하게 된다.According to the present invention, the airbag cushion 4 of the airbag module 2 is deployed from the flow F behind the front seat S according to a control signal generated by the ACU, which receives a signal of a sensor that detects a vehicle collision. To protect the rear passenger (P).

이러한 에어백 쿠션(4)의 전개는 도 1에 도시된 바와 같이 ACU의 신호에 의해 플로우(F)내부에서 에어백 모듈(2)이 작동하게 되면, 에어백 모듈(2)내 인플레이터의 점화에 의해 에어백 쿠션(4)이 팽창되면서 절개선(1a,3a)을 통해 플로우(F)의 도어(3)와 카펫(1)을 젖히게 되고, 이에 따라 에어백 쿠션(4)이 전방시트(S)의 뒤에서 뒷좌석 승객(P)쪽으로 전개되어진다.As shown in FIG. 1, when the airbag module 2 is operated in the flow F by the signal of the ACU, the airbag cushion 4 is ignited by the inflator in the airbag module 2. As the (4) is inflated, the door (3) and the carpet (1) of the flow (F) are flipped through the incisions (1a, 3a), so that the airbag cushion (4) is the rear seat behind the front seat (S). It is deployed toward the passenger P.

이와 같이 전방시트(S)의 뒤에서 뒷좌석 승객(P)쪽으로 전개되는 에어백 쿠션(4)은 도 2에 도시된 바와 같이, 가스 유입 안내부(7)로 구획된 에어백 쿠션(4)의 하부에서 가스가 유입되면, 상기 가스 유입 안내부(7)에 의해 구획된 무릎보호쿠션(6)에 비해 머리보호쿠션(5)쪽으로 우선적으로 가스가 유입되면서 머리보호쿠션(5)쪽이 팽창되어진다.As shown in FIG. 2, the airbag cushion 4 deployed toward the rear seat passenger P from the rear of the front seat S is gas at the bottom of the airbag cushion 4 partitioned by the gas inlet guide 7. When the gas is introduced, the head protection cushion 5 is expanded while the gas is preferentially introduced into the head protection cushion 5 as compared to the knee protection cushion 6 partitioned by the gas inflow guide 7.
