본 발명은 자동차의 커튼 에어백에 관한 것으로, 보다 상세하게는 커튼 에어백의 전개시 센터 필러트림에 끼이면서 불완전하게 전개되지 않고 정상적으로 커튼 에어백이 전개되는 방향으로 유도하도록 한 커튼 에어백의 가이드 장치에 관한 것이다.The present invention relates to a curtain airbag of an automobile, and more particularly, to a guide device of a curtain airbag which is guided in a direction in which a curtain airbag is normally deployed without being incompletely developed while being caught in a center pillar trim when the curtain airbag is deployed. .

일반적으로 에어백 시스템은 탑승자의 안전을 위하여 차량의 탑승자와 차량 구조물 사이에 에어백이 전개되도록 하여 탑승자가 차량 구조물과 직접 부딪히면서 발생하는 충격에 의한 부상을 예방하도록 하고 있다.In general, the airbag system allows the airbag to be deployed between the occupant of the vehicle and the vehicle structure for the safety of the occupant to prevent injuries caused by the impact caused when the occupant directly hits the vehicle structure.

이러한 에어백 시스템은 전방 충돌시 탑승자의 상체 및 머리 부위를 보호하기 위하여 스티어링 휠의 내부 및 글로브 박스의 상측에 장착되는 일반적인 에어백과, 측면 충돌시 탑승자와 도어 사이에서 전개되어 탑승자를 보호하기 위한 커튼 에어백으로 구분된다.This airbag system is a general airbag mounted inside the steering wheel and the upper side of the glove box to protect the upper body and head of the occupant in front of the crash, and a curtain airbag deployed between the occupant and the door in the case of side impact to protect the occupant. Separated by.

종래의 커튼 에어백은 도 1에 도시한 바와 같이, 차량의 측면충돌이 발생되면 센터 필러트림(2)이 실내측으로 돌출된 후에 거의 동시적으로 커튼 에어백(1)이 전개되는데, 이때 커튼 에어백(1)이 센터 필러트림(2)의 벌어진 틈새 사이로 전개되면서 커튼 에어백(1)이 탑승자를 보호하지 못하게 되어 센터 필러트림(2)에 의해 탑승자가 머리에 치명적인 상해를 입는 문제가 있다.In the conventional curtain airbag, as shown in FIG. 1, when the side collision of the vehicle occurs, the curtain airbag 1 is deployed almost simultaneously after the center pillar trim 2 protrudes to the interior side, wherein the curtain airbag 1 ) Is deployed between the gaps between the center pillar trim 2 and the curtain airbag 1 does not protect the occupant, thereby causing a fatal injury to the head of the occupant by the center pillar trim 2.

이와 같은 문제점을 감안하여 안출한 본 발명의 목적은 커튼 에어백의 전개시 센터 필러트림의 벌어진 틈새로 커튼 에어백이 끼여들지 않도록 커튼 에어백의 전개방향을 유도하여 정상적인 커튼 에어백의 전개가 가능하도록 하려는 것이다.The object of the present invention devised in view of the above problems is to induce the curtain airbag to be deployed so that the normal curtain airbag can be deployed so that the curtain airbag is not interrupted by the gap between the center pillar trim when the curtain airbag is deployed.

상기의 목적을 달성하기 위한 본 발명은, 헤드라이닝과 차체의 내측판넬 사이에 설치되어 측면 충돌시 센터 필러트림의 단부와 헤드라이닝의 단부를 가르면서 하방향으로 전개되는 커튼 에어백에 있어서, 상기 커튼 에어백의 외주부를 감싸는 상태로 설치되어 측면 충돌시 상기 센터 필러트림이 벌어지는 틈으로 상기 커튼 에어백이 전개되는 것을 차단하기 위한 램프를 설치하여 구성한 것을 특징으로 한다.In order to achieve the above object, the present invention is installed between the headlining and the inner panel of the vehicle body in the curtain airbag deployed in the downward direction while cutting the end of the center pillar trim and the end of the headlining in the event of a side collision, the curtain It is installed in a state surrounding the outer periphery of the air bag, characterized in that configured to install a lamp to block the curtain air bag deployment to the gap that the center pillar trim is opened in the event of a side impact.

상기 램프는 선단에 절개부가 형성되고, 후단에 힌지부를 구비하여 상기 커튼 에어백의 전개시 절개부가 절단되면서 상기 힌지부를 중심으로 회전되어 커튼 에어백이 상기 센터 필러트림 방향으로 전개되는 것을 차단하는 것이 바람직하다.The lamp has a cutout formed at the front end, and has a hinged part at the rear end thereof, so that the curtain airbag is rotated around the hinge while cutting the cutout when the curtain airbag is deployed, thereby preventing the curtain airbag from being deployed in the center pillar trim direction. .

이하, 상기한 바와 같은 본 발명의 바람직한 실시예를 첨부도면에 의거하여 보다 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention as described above will be described in more detail with reference to the accompanying drawings.

첨부도면 도 2는 본 발명에 의한 커튼 에어백이 설치된 센터 필러트림의 단면도이고, 도 3은 본 발명에 의한 커튼 에어백이 전개된 상태의 단면도이다.2 is a cross-sectional view of a center pillar trim provided with a curtain airbag according to the present invention, and FIG. 3 is a cross-sectional view of a state where the curtain airbag according to the present invention is deployed.

도 2에 도시한 바와 같이, 측면 충돌시 탑승자와 도어 사이에서 전개되어 탑승자에게 가해지는 충격으로부터 탑승자를 보호하기 위한 커튼 에어백(1)이 헤드라이닝(3)과 차체의 내측판넬(4) 사이에 설치되어 있다.As shown in FIG. 2, a curtain airbag 1 is provided between the headlining 3 and the inner panel 4 of the vehicle body to protect the occupant from the impact applied to the occupant during the side collision. It is installed.

이와 같이 헤드라이닝(3)과 내측판넬(4) 사이에 장착되어 충돌감지센서(미도시)에 의한 감지신호에 의해 전개되는 커튼 에어백(1)은 센터 필러트림(2)의 단부와 헤드라이닝(3)의 단부를 가르면서 하방향으로 전개된다.As such, the curtain airbag 1 mounted between the headlining 3 and the inner panel 4 and deployed by a detection signal by a collision detection sensor (not shown) has an end portion of the center pillar trim 2 and the headlining ( It develops downward while cutting the end of 3).

여기서 본 발명은 선단에 절개부(12)가 형성되고 후단에 힌지부(14)가 형성된 램프(ramp)(10)를 커튼 에어백(1)을 감싸는 상태로 설치하여 구성한 것이다.Herein, the present invention is configured by installing a lamp 10 having a cutout portion 12 formed at a front end and a hinge portion 14 formed at a rear end to surround the curtain airbag 1.

램프(10)의 재질은 플라스틱을 사용함으로써 중량을 절감하도록 한다.The material of the lamp 10 is to save weight by using plastic.

이와 같이 구성되는 본 발명에 의해 측면 충돌시 커튼 에어백이 전개되는 동작을 도 3을 참조하여 설명하면 다음과 같다.Referring to FIG. 3, an operation of deploying a curtain airbag during a side impact by the present invention configured as described above is as follows.

차량에 측면 충돌이 발생되면 차체에 충격이 가해지면서 센터 필러트림(2)이 벌어지게 된다. 그리고 이어서 커튼 에어백(1)이 전개되는데, 커튼 에어백(1)의 전개시 커튼 에어백(1)을 감싸고 있는 램프(10)가 커튼 에어백(1)이 전개되는 힘에 의해 선단에 형성된 절개부(12)가 절단되면서 램프(10)는 힌지부(14)를 중심으로 180°회전된다. 따라서 회전되는 램프(10)는 측면 충돌에 의해 차체에서 돌출되면서 벌어진 상태의 센터 필러트림(2)을 차단하는 상태가 된다.When a side collision occurs in the vehicle, the center pillar trim 2 is opened while an impact is applied to the vehicle body. Subsequently, the curtain airbag 1 is unfolded, and when the curtain airbag 1 is unfolded, the lamp 10 surrounding the curtain airbag 1 is formed at the distal end portion 12 by the force of the curtain airbag 1 being deployed. The lamp 10 is rotated 180 ° about the hinge portion 14 while cutting the lamp 10. Therefore, the rotating lamp 10 is in a state of blocking the center pillar trim 2 in the open state while protruding from the vehicle body by the side collision.

이처럼 램프(10)가 센터 필러트림(2)을 차단하는 상태에서 커튼 에어백(1)이 전개되므로 커튼 에어백(1)이 완전히 전개되는 압력에 의해 램프(10)는 도 3에 도시한 바와 같이, 커튼 에어백(1)에 의해 센터 필러트림(2)의 벌어진 틈새를 차단하여 감싸는 상태가 된다.As the curtain airbag 1 is deployed in the state in which the lamp 10 blocks the center pillar trim 2 as described above, the lamp 10 is shown in FIG. 3 by the pressure at which the curtain airbag 1 is fully deployed. The air gaps 1 of the center pillar trim 2 are blocked and wrapped by the curtain airbag 1.

따라서 커튼 에어백(1)은 센터 필러트림(2)의 벌어진 틈새 사이로 전개되지 않고 정상적으로 탑승자와 차체 사이의 공간부로 전개되므로 탑승자에게 가해지는 충격을 흡수할 수 있게 된다. Therefore, the curtain airbag 1 is not deployed between the gaps of the center pillar trim 2 but is normally deployed in the space between the passenger and the vehicle body, thereby absorbing the shock applied to the passenger.

이상에서 설명한 바와 같이, 본 발명에 의한 커튼 에어백의 전개방향 가이드 장치는 커튼 에어백의 전개시 센터 필러트림이 벌어지는 틈새 사이로 커튼 에어백이 전개되는 것을 차단하여 측면 충격으로부터 탑승자를 보호하는 효과가 있다.As described above, the curtain airbag deployment direction guide device according to the present invention has the effect of protecting the occupant from the side impact by blocking the deployment of the curtain airbag between the gap that the center pillar trim is opened when the curtain airbag is deployed.

따라서 최근 전차종에 적용되는 커튼 에어백의 작동성능이 현저하게 개선되어 소비자의 신뢰도를 향상시키게 된다.
Therefore, the operation performance of the curtain airbag applied to all recent models is significantly improved to improve the consumer's reliability.
