본 발명은 자동차용 에어백의 작동후 자동제거장치에 관한 것으로 특히 운전대에 장착된 에어백이 전개되어 충격력을 완화시킨후 주입 가스가 흡기매니폴드를 통해 빠져나감으로써 에어백이 신속히 제거되어 운전에 방해가 되지 않도록 한 것이다.The present invention relates to an automatic removal device after the operation of the airbag for automobiles, in particular, after the airbag mounted on the steering wheel is deployed to relieve the impact force, the injected gas is released through the intake manifold so that the airbag is quickly removed to prevent operation. It is to avoid.
대부분의 차량에는 운전대에 에어백이 설치되어 있으며 이러한 에어백은 차량이 충돌하였을때 운전자의 부상을 최소화시키기 위한 운전자용 시트밸트의 보조 장치인 것이다. 특히 운전대에 설치된 에어백은 운전자의 머리를 포함한 상반신을 보호하는 역할을 하는 것으로 작동은 다음과 같다.Most vehicles are equipped with airbags on the steering wheel, which is an auxiliary device of the driver's seat belt to minimize the driver's injury when the vehicle crashes. In particular, the airbag installed on the steering wheel protects the upper body including the driver's head. The operation is as follows.
종속(약20km/h)이상에서 차량이 전방 충돌할 경우 패드커버(pad cover)내에접혀 있는 에어백에 압축 가스가 주입되어 순간적으로 팽창한다. 에어백이 팽창함에 따라 페드커버가 갈라지고 운전대에 내장된 에어백이 밖으로 튀어나온다. 그리고 전방으로 쏠리는 운전자에 접촉된다. 이어서 에어백은 완전히 팽창상태가 되고 이때까지 소요되는 시간은 3/100초 내외가 된다. 이렇게 완전히 팽창된 에어백은 배출공을 통해 가스가 서서히 배출되면서 운전자에게 전달되는 충격력을 완화시켜주게 된다. 그러나 종래의 에어백은 전개되어 운전자에게 전달되는 충격력을 완화시켜준 후에도 가스가 완전히 배출되는데 까지는 상당한 시간이 소요되게 되며 이동안 에어백은 운전대를 조작하는데 지장을 초래하여 2차/3차 충돌사고를 일으킬 염려가 있었다. 특히 고속주행시 고르지 못한 도로면에 의해 차체에 충격이 가해짐으로써 에어백이 오작동되는 경우에는 대형사고를 피할 수 없었다. 즉 에어백은 작동후 신속히 제거되는 것이 바람직하나 종래의 에어백은 작동후에도 상당한 시간동안 가스가 주입된 상태를 유지하기 때문에 에어백이 작동후 신속히 제거될 수 있게하는 수단이 절실히 요구되어 왔다.When the vehicle collides forward in the cascade (about 20 km / h) or more, compressed gas is injected into the airbag folded in the pad cover and inflates momentarily. As the airbag inflates, the ped cover cracks and the airbag built into the steering wheel pops out. And the driver is pulled forward. The airbag is then fully inflated and the time required is about 3/100 seconds. This fully inflated airbag relieves the impulse delivered to the driver as the gas is slowly released through the vent hole. However, even after the conventional airbag has been released and alleviated the impact force transmitted to the driver, it takes a long time for the gas to be discharged completely. During this time, the airbag may interfere with the steering wheel, causing secondary / third crash accidents. There was concern. In particular, a large accident could not be avoided if the airbag malfunctioned due to the impact on the body due to the uneven road surface during high-speed driving. That is, it is desirable that the airbag be removed quickly after operation, but since the conventional airbag keeps gas injected for a considerable time even after operation, a means for allowing the airbag to be removed quickly after operation has been urgently required.
본 발명은 이와같은 점을 감안하여 안출한 것으로서 에어백이 작동후 약 3mmHg의 진공사태인 흡기매니폴드와 연통되게 하여 에어백내의 가스가 신속히 배출될수 있게 함으로써 운전대를 조작하는데 지장을 초래하지 않도록 하여 2차/3차 충돌사고를 미연에 방지하는 것을 주목적으로 한다.The present invention has been made in view of this point, and the airbag is in communication with the intake manifold, which is about 3mmHg vacuum after operation, so that the gas in the airbag can be discharged quickly, thereby preventing the operation of the steering wheel. The main purpose is to prevent the third collision accident.
상술한 본 발명의 목적은 에어백을 흡기매니폴드에 연결시키는 가스배출튜브와, 상기 가스배출튜브에 설치되어 스테핑(stepping)모터에 의해 작동되는 개폐밸브와, 에어백 작동시 온되는 작동스위치와, 상기 작동스위치의 온신호에 의해 스테핑모터를 작동시켜 개폐밸브를 열어주는 ECU에 의하여 달성되어 진다.An object of the present invention described above is a gas discharge tube for connecting an air bag to an intake manifold, an on / off valve installed on the gas discharge tube and operated by a stepping motor, an operation switch to be turned on when the air bag is operated, and This is achieved by the ECU which opens the on / off valve by operating the stepping motor by the ON signal of the operation switch.
이하 본 발명의 바람직한 실시예를 첨부도면에 의거 상세히 설명하면 다음과같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
차량충돌 사고시 에어백(1)에 압축가스가 주입되어 전개되는 것에 있어서, 상기 에어백(1)을 흡기매니폴드(3)에 연결시키는 가스배출튜브(2)와, 상기 가스배출튜브 (2)에 설치되어 스테핑 모터(5)에 의해 작동되는 개폐밸브(4)와, 에어백(1)의 작동시 온되는 작동스위치(6)와, 상기 작동스위치(6)의 온신호에 스테핑 모터(5)를 작동시켜 개폐밸브(4)를 열어주는 ECU(7)로 구성된 것이다.In the event of a vehicle crash, the compressed gas is injected into the air bag 1 to be deployed. The gas discharge tube 2 connecting the air bag 1 to the intake manifold 3 and the gas discharge tube 2 are installed. To operate the stepping motor 5 in response to the on / off signal of the on / off valve 4 actuated by the stepping motor 5, the actuating switch 6 which is turned on when the airbag 1 is operated, and the actuating signal of the actuating switch 6. It is composed of the ECU (7) for opening the on-off valve (4).
이와같이 된 본 발명의 작동스위치(6)는 에어백(1)의 직동여부를 감지하는 수단이다. 또한 가스배출튜브(2)에 구비된 개폐밸브(4)는 스테핑모터(5)를 별도로 장착시키지 않는 솔레노이드 밸브를 사용하여 ECU(7)에 이해 제어되도록 할 수도 있다.The operation switch 6 of the present invention as described above is a means for detecting whether the airbag (1) is linear. In addition, the on / off valve 4 provided in the gas discharge tube 2 may be controlled by the ECU 7 by using a solenoid valve that does not separately mount the stepping motor 5.
제1도 및 제2도는 에어백(1)을 주행시 약 3mmHg의 진공이 걸리는 흡기매니폴드(3)에 가스배출튜브(2)로 연결 설치한 상태를 보이기 위한 도면이다.1 and 2 are diagrams for showing the state in which the air bag 1 is connected to the intake manifold 3 to which the vacuum of about 3 mmHg is applied with the gas discharge tube 2 while traveling.
차량의 충돌 사고가 발생하거나 고속 주행중 불규칙한 도로에 의해 차체에 충격이 가해짐으로써 압축가스가 에어백(1)에 주입되면 에어백(1)이 순간적으로 팽창하게 되고, 이에따라 패드커버가 갈라지고 스티어링 휠(8)에 내장된 에어백(1)이 운전자를 향해 전개되는데 이와동시에 작동스위치(6)는 온되게 된다. 즉 작동스위치(6)는 에어백(1)의 작동여부를 감지하여 온신호를 ECU(7)에 입력하게 되고, ECU(7)에서는 작동스위치(6)의 온신호에 의해 스테핑 모터(5)를 작동시킴으로서 개폐밸브(4)를 열어주게 된다. 개폐밸브(4)가 열리게 되면 에어백(1)은 흡기매니폴드(3)와 연통되게 되고, 상기 흡기매니폴드(3)는 약 3mmHg의 진공상태이기 때문에 에어백(1)에 주입된 가스가 가스배출튜브(2) 및 흡기매니폴드(3)를 통해 배출된다. 에어백(1)의 가스는 불과 2∼3초안에 완전히 배출되어 에어백(1)이 수축됨으로써 운전자는 에어백(1)에 의해 방해받지 않고 운전대를 조작할 수 있게 된다. 흡기매니폴드(3)를 통해 주입가스가 배출되어 에어백(1)이 신속히 제거된다는 것은 충돌사고후 운전자가 적절히 대응함으로서 2차/3차 충동을 예방할 수 있다는 것을 의미하며, 특히 고속주행중 차체에 가해진 충격에 의해 에어백(1)의 오작동이 일어났을 경우에도 운전자가 무방비 상태에서 대형사고를 일으키지 않도록 대처할 수 있게 하는 효과가 있는 것이다.When compressed gas is injected into the airbag 1 due to a crash of the vehicle or an impact on the vehicle body due to an irregular road during high-speed driving, the airbag 1 is momentarily inflated. Accordingly, the pad cover is cracked and the steering wheel ( The airbag 1 embedded in 8 is deployed toward the driver, and at the same time, the operation switch 6 is turned on. That is, the operation switch 6 detects the operation of the airbag 1 and inputs an on signal to the ECU 7, and the ECU 7 operates the stepping motor 5 by the on signal of the operation switch 6. By opening the on-off valve (4) is opened. When the on-off valve 4 is opened, the air bag 1 is in communication with the intake manifold 3, and since the intake manifold 3 is in a vacuum state of about 3 mmHg, the gas injected into the air bag 1 discharges gas. It is discharged through the tube (2) and the intake manifold (3). The gas of the airbag 1 is completely discharged in only 2 to 3 seconds and the airbag 1 is contracted so that the driver can operate the steering wheel without being disturbed by the airbag 1. The rapid removal of the airbag 1 by the injection gas discharged through the intake manifold 3 means that the driver responds appropriately after the crash to prevent secondary / third impulses. Even when a malfunction of the airbag 1 occurs due to the impact, the driver is able to cope with a large accident in a defenseless state.
이와같이 본 발명은 에어백(1)이 작동후 약 3mmHg의 진공상태인 흡기매니폴드(3)와 연통되게 하여 에어백(1)내의 가스가 신속히 배출될 수 있게 함으로써 운전대를 조작하는데 지장을 초래하지 않도록 하여 에어백(1)의 오동작으로 인한 대형사고 및 1차 충돌후의 2차/3차 충돌사고를 미연에 방지할 수 있게 한 것이다.As such, the present invention allows the airbag 1 to communicate with the intake manifold 3 in a vacuum state of about 3 mmHg after operation so that the gas in the airbag 1 can be discharged quickly, thereby preventing the operation of the steering wheel. It is possible to prevent large accidents caused by malfunction of the airbag 1 and secondary / third collision accidents after the first collision.
