본 발명은 차량용 사이드 에어백에 관한 것으로서, 보다 상세하게는 루프패널과 헤드라이너 사이의 차체 내부에 설치된 에어백 튜브가 차량의 충돌시 차실내로 안정적으로 전개되게 하여, 탑승자를 2차 부상으로부터 안전하게 보호하는 차량용 사이드 에어백의 전개유도구조에 관한 것이다.The present invention relates to a vehicle side airbag, and more particularly, to ensure that the airbag tube installed inside the vehicle body between the roof panel and the headliner is stably deployed into the cabin in the event of a vehicle collision, thereby protecting the occupant from secondary injuries. A deployment guide structure of a side airbag for a vehicle.

일반적으로, 차량에 설치되는 에어백은 안전벨트와 더불어서 차량의 충돌시 탑승자를 부상으로부터 최대한 보호하기 위한 장치이다.In general, the airbag installed in the vehicle is a device for protecting the occupant from injury in the event of a collision with the seat belt.

이러한 에어백은 통상적으로 운전석의 스티어링휠과 조수석의 인스트루먼트패널과 차량의 사이드 즉 도어와 인접한 헤드라이너와 루프패널 사이에 각각 설치되고, 차량의 충돌시 충돌감지센서와 전자제어유닛(Electronic Control Unit : 이 하 "ECU"라 한다)에 의해 안전벨트와 같이 연동되어 탑승자를 부상으로부터 최대한 보호하게 된다.These airbags are typically installed between the steering wheel of the driver's seat and the driver's seat and the vehicle's side, that is, between the headliner and roof panel adjacent to the door. "ECU") is linked with a seat belt to protect the occupant from injury as much as possible.

즉, 차량의 충돌시, 충돌감지센서가 이의 감지신호를 ECU로 출력하고, 상기 ECU는 충격강도에 따라 에어백의 작동여부를 판단하여 에어백을 작동시킬 필요가 있을 때에는 인플레이터(Inflator)를 작동시켜 에어백을 팽창시킨다.That is, when the vehicle crashes, the collision detection sensor outputs its detection signal to the ECU, and when the ECU needs to determine whether the airbag is operated according to the impact strength, it is necessary to operate the airbag by operating the inflator. Inflate.

이때, 인플레이터(Inflator)는 접어져 설치된 에어백에 연결되고, ECU에 의해 작동될 시에는 그 내부의 히터가 발열하여 화약을 착화시키고 가스발생제를 연소시켜 순간적으로 발생된 다량의 질소가스(이하, "가스"라 한다)가 에어백으로 신속하게 분사되어 에어백을 팽창시키게 된다.At this time, the inflator is connected to an airbag installed in a folded state, and when operated by an ECU, a heater inside thereof generates heat to ignite the gunpowder and to burn a gas generating agent. "Gas" is quickly injected into the airbag to inflate the airbag.

따라서, 이와 같이 작동되는 에어백은 차량의 충돌시 팽창되면서 탑승자의 머리와 흉부 부위를 충격으로부터 보호하게 된다.Thus, the airbag operated as described above is inflated during the collision of the vehicle, thereby protecting the occupant's head and chest from impact.

특히, 차량의 사이드 에어백은, 차량의 측면 충돌시 측면 충격력으로 인해 탑승자가 차량의 내측면에 부딪혀 입는 2차 부상을 방지하기 위한 것으로, 이를 첨부도면 도 1 내지 도 3을 참조하여 설명한다.In particular, the side airbag of the vehicle is for preventing secondary injuries caused by the occupant hitting the inner surface of the vehicle due to the side impact force during the side impact of the vehicle, which will be described with reference to FIGS. 1 to 3.

도 1에 도시된 바와 같이, 종래의 사이드 에어백(이하, "에어백 모듈"로 통칭함)(10)은 루프패널(미도시)과 헤드라이너(4) 사이의 양측단부에 내장되어, 센터필라 즉 B-필라(이하, "센터필라"로 통칭함) 측으로 전개되게 설치된다.As shown in FIG. 1, a conventional side airbag (hereinafter referred to as "airbag module") 10 is embedded at both end portions between the roof panel (not shown) and the headliner 4, thereby providing a center pillar. It is installed to be deployed to the B-pillar (hereinafter referred to as "center pillar").

상기와 같이 설치된 에어백 모듈(10)의 일단에는, 차량의 충돌시 전달되는 충격강도에 따라 ECU(미도시)에 의해 제어되어 에어백 튜브(16)내로 다량의 가스를 고압 분사하는 인플레이터(20)가 설치된다.At one end of the airbag module 10 installed as described above, an inflator 20 which is controlled by an ECU (not shown) according to the impact strength transmitted when a vehicle collides, and injects a large amount of gas into the airbag tube 16 at high pressure. Is installed.

이를 도 2를 참고로 좀 더 자세히 설명하면, 루프패널과 헤드라이너(4) 사이에는 다수의 인너패널(6)과 보강브라켓(8)이 내장되어 설치되고, 헤드라이너(4)의 양측단부에는 내장재인 도어트림과 센터필라트림(2)이 접하여 설치된다.2, a plurality of inner panels 6 and a reinforcement bracket 8 are installed between the roof panel and the headliner 4, and both ends of the headliner 4 are installed. The door trim and the center pillar trim (2), which are interior materials, are installed in contact with each other.

즉, 헤드라이너(4)의 양측단부는 인너패널(6)측으로 단차지게 절곡된 걸림턱(4a)이 형성되고, 이 걸림턱(4a)에는 센터필라트림(2)의 상단부가 접하여 설치된다.That is, both side ends of the headliner 4 are provided with a locking step 4a bent stepwise toward the inner panel 6 side, the upper end of the center pillar trim (2) is provided in contact with the locking step (4a).

이와 같이 설치된 헤드라이너(4)와 센터필라트림(2)의 경계부상에 에어백 모듈(10)이 근접되게 위치되어 설치된다.The airbag module 10 is located in close proximity to the headliner 4 and the center pillar trim 2 provided as described above.

상기 에어백 모듈(10)은, 그 하우징(12)의 일측 즉 마운팅부(12a)가 인너패널(6)에 볼팅되고, 하우징(12) 내부에는 인플레이터(20)에 의해 인플레이터(20)에 인접한 부위부터 순차적으로 팽창되면서 전개되는 에어백 튜브(16)가 포개진 상태로 내장되며, 하우징(12)의 일측에는 에어백 튜브(16)의 전개시 튜브(16)에 의해 개구되는 도어(12b)가 설치된다.In the airbag module 10, one side of the housing 12, that is, the mounting portion 12a is bolted to the inner panel 6, and the inside of the housing 12 is adjacent to the inflator 20 by the inflator 20. The airbag tube 16, which is expanded while being sequentially inflated, is embedded in a superimposed state, and one side of the housing 12 is provided with a door 12b opened by the tube 16 when the airbag tube 16 is deployed. .

특히, 에어백 튜브(16)에 의해 개구되는 하우징(12)의 도어(12b)는, 에어백 튜브(16)의 전개시 도어(12b)의 상단부가 하우징(12)으로부터 탈거되면서 회전되어 센터필라트림(2)의 상단부에 접하면서 센터필라트림(2)과 인너패널(6) 사이의 공간을 폐쇄시킴으로써 에어백 튜브(16)의 전개를 안정적으로 유도하게 된다.In particular, the door 12b of the housing 12 opened by the airbag tube 16 is rotated while the upper end of the door 12b is removed from the housing 12 when the airbag tube 16 is deployed. By closing the space between the center pillar trim 2 and the inner panel 6 while contacting the upper end of 2), the deployment of the airbag tube 16 is stably induced.

이는, 헤드라이너(4)의 측단부와 접하는 센터필라트림(2)이 시트벨트(미도시)가 내장되어 설치되는 등의 연유로 인해 헤드라이너(4)로부터 차실내측으로 더 돌출되게 설치되어 있어, 전개되는 에어백 튜브(16)가 센터필라트림(2)과 인너패널(6) 사이의 공간으로 유입되는 것을 막기 위함이다.This is because the center pillar trim 2 which is in contact with the side end of the headliner 4 is installed to protrude further from the headliner 4 to the interior of the vehicle due to the installation of a seat belt (not shown). In order to prevent the airbag tube 16 deployed from being introduced into the space between the center pillar trim 2 and the inner panel 6.

그리고, 하우징(12)의 하면 즉 센터필라트림(2)에 인접한 면에는, 에어백 튜브(16)의 전개시 인너패널(6)과 접하여 하우징(12) 하면의 회전을 제어함으로써 도어(12b)가 센터필라트림(2)에 안정적으로 접할 수 있도록 한 안내판(14)이 설치된다.On the lower surface of the housing 12, that is, the surface adjacent to the center pillar trim 2, the door 12b is contacted by controlling the rotation of the lower surface of the housing 12 in contact with the inner panel 6 when the airbag tube 16 is deployed. A guide plate 14 is installed to stably contact the center pillar trim 2.

즉, 에어백 튜브(16)의 전개시는 하우징(12)으로부터 도어(12b)의 상단부가 탈거됨과 동시에 하우징(12) 하면이 하방향으로 밀려 회전되는데, 이때 하우징(12) 하면과 이격된 안내판(14)이 인너패널(6)에 접하면서 하우징(12) 하면의 회전량을 제어하여 도어(12b)가 안정적으로 센터필라트림(2)의 상단부에 접하게 하여, 센터필라트림(2)과 인너패널(6) 사이의 공간을 차단시킴으로써 이 공간으로 에어백 튜브(16)가 유입되는 것을 방지하였다.That is, when the airbag tube 16 is deployed, the upper end of the door 12b is removed from the housing 12 and the lower surface of the housing 12 is pushed downward and rotated. At this time, the guide plate spaced apart from the lower surface of the housing 12 ( While the 14 is in contact with the inner panel 6, the amount of rotation of the lower surface of the housing 12 is controlled so that the door 12b is stably in contact with the upper end of the center pillar trim 2, so that the center pillar trim 2 and the inner panel are in contact with each other. The airbag tube 16 was prevented from entering the space by blocking the space between the spaces (6).

따라서, 에어백 튜브(16)의 전개시는 도 2에 가상선으로 도시된 바와 같이, 안내판(14)과 하우징(12)의 도어(12b)에 의해 센터필라트림(2)과 인너패널(6) 사이의 공간부가 차단됨으로써 전개되는 에어백 튜브(16)가 센터필라트림(2)과 인너패널(6) 사이의 공간으로 전개되지 않고 차실내로 안정적으로 전개되어 탑승자의 측면부위 특히 머리 부위를 효과적으로 보호하였다.Accordingly, when the airbag tube 16 is deployed, the center pillar trim 2 and the inner panel 6 are guided by the guide plate 14 and the door 12b of the housing 12, as shown in FIG. The airbag tube 16, which is deployed by blocking the space portion between the two, is stably deployed into the cabin without being deployed into the space between the center pillar trim 2 and the inner panel 6, thereby effectively protecting the occupant's side, especially the head. It was.

이때, 상기와 같이 개구되는 도어(12b)에 의해서 헤드라이너(4)의 측단부는 도 3과 같은 개방라인을 형성하면서 센터필라트림(2)의 상단부로부터 이탈되는 한편 도 2에 가상선으로 도시된 바와 같이 벤딩되어, 에어백 튜브(16)가 토출되어 전 개될 수 있는 출구를 형성하게 된다.At this time, the side end of the headliner 4 is separated from the upper end of the center pillar trim 2 by forming the open line as shown in FIG. As can be bent, the airbag tube 16 is discharged to form an outlet through which it can be deployed.

한편, 상기와 같이 에어백 튜브(16)가 전개될 때, 고속 고압으로 팽창되는 에어백 튜브(16)에 의해 헤드라이너(4)는 도 3에 도시된 바와 같은 개방라인을 형성하면서 에어백 튜브(16)의 전개를 유도하게 된다.On the other hand, when the airbag tube 16 is deployed as described above, the airbag tube 16 forms an open line as shown in FIG. 3 by the airbag tube 16 expanding at high pressure and high pressure. Will lead to the development of.

그러나, 이와 같이 개방되는 헤드라이너(4)는 에어백 튜브(16)의 전개작동과 같이 인플레이터(20)가 위치한 차량 후방측에서 전방측으로 순차적으로 벤딩되면서 개방되는데, 이때 헤드라이너(4)의 개방라인은 도 3과 같이 최초 설치위치로부터 센터필라트림(2)측에서만 차실내로 더 돌출되게 벤딩되고 이 벤딩부위와 수직하게 꺾인 센터필라트림(2) 양편의 헤드라이너(4)는 최초 설치위치보다 오히려 차체바디 즉 인너패널(6)측으로 더 밀려 나가는 개방라인을 갖게 되므로써 센터필라트림(2) 주변의 헤드라이너(4)가 매끄럽게 개방되지 못하고, 그로 인해 에어백 튜브(16)의 전개가 전반적으로 매끄럽게 이루어지지 못해, 탑승자를 2차 부상으로부터 보호하지 못하게 되는 치명적인 문제점이 있었다.However, the headliner 4 opened in this way is opened while being sequentially bent from the rear side of the vehicle in which the inflator 20 is located to the front side, such as the deployment operation of the airbag tube 16, in which the opening line of the headliner 4 is opened. As shown in FIG. 3, the headliners 4 on both sides of the center pillar trim 2 which are bent to protrude further into the interior of the vehicle only from the center pillar trim 2 from the initial installation position are bent from the initial installation position. On the contrary, since the headline 4 around the center pillar trim 2 cannot be smoothly opened by having an open line pushed further toward the body body, that is, the inner panel 6, the deployment of the airbag tube 16 is smooth overall. There was a fatal problem that could not be achieved, which would not protect the occupants from secondary injuries.

이에, 본 발명은 전술한 바와 같은 종래기술의 문제점을 해결하기 위해 안출된 것으로, 루프패널과 헤드라이너 사이에 에어백 모듈을 지지하는 지지브라켓을 형성하여, 에어백 튜브의 전개시 지지브라켓에 의해 헤드라이너가 매끄럽고 신속하게 개방되므로써 에어백 튜브가 차실내로 신속하면서도 안정적으로 전개되어, 차량 의 충돌시 탑승자를 차체바디와의 부딪힘으로 인한 2차 부상으로부터 안전하게 보호할 수 있도록 한 차량용 사이드 에어백의 전개유도구조를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the problems of the prior art as described above, by forming a support bracket for supporting the airbag module between the roof panel and the headliner, the headliner by the support bracket during deployment of the airbag tube The airbag tube is deployed quickly and stably in the interior of the vehicle by the smooth and quick opening, so that the induction structure of the side airbag for the vehicle can be secured to protect the occupant from the secondary injury caused by the collision with the body body when the vehicle crashes. The purpose is to provide.

상술한 목적을 달성하기 위한 본 발명은, 루프패널과 헤드라이너 사이에 내장되게 설치되고, 하우징에 내장되어 팽창되는 에어백 튜브가 하우징과 헤드라이너를 순차적으로 개방시키면서 차실내로 전개되는 차량용 사이드 에어백 모듈에 있어서,
센터필라트림 양편의 루프패널과 헤드라이너 사이의 인너패널에 고정되고 에어백 모듈의 하부를 지지하는 지지브라켓이 구성되며, 상기 지지브라켓은, 루프패널과 헤드라이너 사이의 인너패널에 고정되는 수직부와, 이 수직부로부터 연장 형성되어 인너패널에 고정된 에어백 모듈의 하부를 받쳐 지지하는 중공의 수평지지부가 형성되며, 상기 수평지지부는 센터필라트림측으로부터 멀어질수록 그 중공의 크기가 점차적으로 축소되게 형성된 것을 특징으로 한다.In order to achieve the above object, the present invention provides a vehicle side airbag module installed between the roof panel and the headliner and having an airbag tube that is built into the housing and expands into the vehicle while sequentially opening the housing and the headliner.
