Abstract

A curtain air bag device for protecting the head of a passenger is provided to ensure smooth deployment of the air bag by guiding a pillar ramp to be slid on a pillar trim. A curtain air bag device for protecting the head of a passenger includes a curtain type air bag(13), a piller ramp member(16), slit grooves(18), a bracket(17), and a bolt fixing member(20). The curtain type air bag is accommodated between a chassis body(11), a pillar trim member(12), and a head liner. The piller ramp member surrounds the curtain type air bag and is widened when the curtain type air bag is deployed. The slit grooves are formed at both upper ends of the pillar ramp part. The bracket is inserted into the slit grooves at its lower end. The bolt fixing member fixes the bracket to the chassis body.

본 발명은 차량 탑승자의 머리 보호를 위한 커튼형 에어백 장치에 관한 것이다.The present invention relates to a curtain airbag device for protecting the head of a vehicle occupant.

차량의 운전석 및 조수석에는 차량의 충돌시 탑승자의 머리를 보호하기 위하여 도 4에 도시하는 것과 같이 천장부위에 커튼형 에어백(1)을 접어 가이드 플레이트(2)에 의해 수용 및 보호토록 한 상태에서 지붕사이드 멤버 인너패널(3)에 볼트고정구(4)를 통해 장착하고 있다.(미국특허 제 6,305,707호 참조)In the driver's seat and the passenger seat of the vehicle, in order to protect the occupant's head in the event of a collision, the roof-type airbag 1 is folded on the ceiling to receive and protect the roof by a guide plate 2, as shown in FIG. It is attached to the side member inner panel 3 through the bolt fastener 4 (refer US patent 6,305,707).

이에따라 차량에 충격력이 가해지면 커튼형 에어백(1)의 내부에 급속히 가스가 충진되면서 부풀어 올라 기둥장식부재(5, 필러 트림부재)의 상부끝단부(5a)에 의해 지지되고 있는 지붕헤드라이닝(6)이 점선도시 상태와 같이 끝단부(5a)로 부터 이탈되면서 부풀어오르는 커튼형 에어백(1)이 펼쳐져 차실내로 유입되며, 이와같은 상태에서 관성력에 의해 전방으로 쏠리게 되는 탑승자의 머리가 풍선처럼 팽창된 에어백(1, 일점쇄선)에 받쳐 지지되므로써 전면 유리창에 머리를 부딪히거나 고개가 꺽어지는 현상을 방지하게 되는 것이다.Accordingly, when an impact force is applied to the vehicle, the roof head lining 6 supported by the upper end portion 5a of the pillar decorative member 5 (filler trim member) is swollen up while rapidly filling gas inside the curtain airbag 1. As shown in the dotted line state, the bulging curtain-type airbag (1) is inflated as it is separated from the end portion (5a) and flows into the cabin. It is supported by the airbag (1, dashed line), which prevents the head from hitting the windshield or the head bent.

그러나 상기한 종래 구조에 의하면 커튼형 에어백(1)이 전개시 지붕헤드라이닝(6)을 밀면서 차실내로 팽창하게 될 때 에어백(1)이 좌우로 흔들려 불안정한 거동 상태를 보이게 되는 점과 기둥장식부재(5)에 걸려 에어백이 전개되지 아니하는 전개불량을 유발하는 문제점이 있었다.However, according to the conventional structure described above, when the airbag 1 expands into the cabin while pushing the roof head lining 6 when the curtain airbag 1 is deployed, the airbag 1 swings from side to side to show an unstable behavior and a pillar decoration member. There was a problem that caused the deployment failure that the airbag is not caught (5).

이에 본 발명은 상기한 점을 감안하여 제안한 것으로서 그의 목적으로 하는 것은Accordingly, the present invention has been proposed in view of the above-described aspects, and has as its object

차량 충돌시 탑승자의 머리를 보호하기 위해 전개되는 커튼형 에어백이 좌우로의 흔들림이 없이 안정적으로 전개되며, 전개되는 도중에 걸림되는 부분이 없어 작동의 안정성이 확보되는 차량 탑승자의 머리보호를 위한 커튼형 에어백 장치를 제공하는 데 있다.Curtain-type airbags that are deployed to protect the occupant's head in the event of a vehicle crash are stably deployed without shaking from side to side. An airbag device is provided.

상기한 목적을 달성하기 위하여 본 발명은The present invention to achieve the above object

차체바디와 필러 트림부재 및 헤드라이너 사이에 수용되어 헤드라이너를 밀치고 전개되는 커튼형 에어백과;A curtain airbag received between the body body, the filler trim member, and the headliner to push and deploy the headliner;

그 커튼형 에어백을 감싸고 있으며, 커튼형 에어백이 전개될 때 벌어지게 되는 필러 램프부재와;A filler lamp member surrounding the curtain airbag, which is opened when the curtain airbag is deployed;

상기 필러 램프부재 상부의 양단에 형성되는 슬릿홈과;Slit grooves formed on both ends of the filler lamp member;

상기 양측 슬릿홈에 하단이 끼워지는 브라켓트와;A bracket to which lower ends are fitted into both slit grooves;

그 브라켓트를 상기 차체 바디에 고정하는 볼트고정구; 를 포함하여 구성된 것을 특징으로 한다.A bolt fixture for fixing the bracket to the vehicle body; Characterized in that configured to include.

이하에 본 발명의 구성을 첨부한 도면을 참조하여 설명한다.The configuration of the present invention will be described below with reference to the accompanying drawings.

도 1은 본 발명에 의한 차량 탑승자의 머리보호를 위한 커튼형 에어백 장치를 나타내는 도면이며, 도 2는 본 발명에 의한 커튼형 에어백 장치의 단면도이며, 도 3은 본 발명에 의한 커튼형 에어백의 작동시의 상태를 나타내는 도면이다.1 is a view showing a curtain airbag device for protecting the head of a vehicle occupant according to the present invention, Figure 2 is a cross-sectional view of the curtain airbag device according to the present invention, Figure 3 is the operation of the curtain airbag according to the present invention It is a figure which shows the state of city.

도면에 있어 부호 11은 차체바디이며, 부호 12는 필러 트림부재이고, 부호 13은 헤드라이너이다.In the figure, reference numeral 11 denotes a body body, reference numeral 12 denotes a filler trim member, and reference numeral 13 denotes a headliner.

상기한 차체바디(11)와 필러 트림부재(12) 및 헤드라이너(13) 사이의 공간부(14)에는 커튼형 에어백(15)이 필러 램프부재(16)에 둘러싸여져 설치되어 있다.In the space 14 between the body body 11, the filler trim member 12, and the headliner 13, a curtain airbag 15 is surrounded by the filler lamp member 16.

이 필러 램프부재(16)는 종래의 경우 차체 구조물에 직접 볼트 체결에 의해 고정되는데 반하여, 본 발명의 경우에 있어서는 필러 램프부재(16)가 브라켓트(17)를 개재하여 간접적으로 차체바디(11)에 고정설치되고 있다.While the filler lamp member 16 is fixed by bolting directly to the vehicle body structure in the related art, in the case of the present invention, the filler lamp member 16 is indirectly connected to the body body 11 via the bracket 17. It is fixedly installed.

상기한 필러 램프부재(16)는 2개의 단부(16a)(16b)가 서로 겹쳐져 상자형태를 취하므로써 그 내부에 커튼형 에어백(15)을 수용하게 되며, 필러 램프부재(16)의 상면(16c)의 양측에는 슬릿홈(18)(18)이 형성되어 있고, 그 슬릿홈(18)(18)에 상기 브라켓트(17)(17)의 하단이 끼워져 지지하는 구조를 취하고 있다.The filler lamp member 16 has the two end portions 16a and 16b overlapping each other to take the form of a box to accommodate the curtain airbag 15 therein, and the upper surface 16c of the filler lamp member 16. Slit grooves 18 and 18 are formed on both sides of the slit, and the lower ends of the brackets 17 and 17 are fitted into the slit grooves 18 and 18 so as to support them.

그리고 상기 브라켓트(17)(17)는 보조핸들 브라켓트(19)(19)를 겹쳐 고정볼트(20)로서 차체바디(11)측에 고정되도록 설치되며, 상기 필러 램프부재(16)의 접혀지는 모서리부에는 노치부(21)가 형성되어 있다.In addition, the brackets 17 and 17 overlap the auxiliary handle brackets 19 and 19 and are installed to be fixed to the body body 11 side as the fixing bolts 20, and the corners of the filler lamp member 16 are folded. The notch part 21 is formed in the part.

이와같은 본 발명은 차량의 충돌을 센서가 감지하면 커튼형 에어백(15)내에 팽창가스가 급속히 충진되면서 부풀어오르게 되며, 이에따라 보호체인 필러 램프부재(16)가 노치부(21)를 기준점으로 벌어져 펼쳐지게 되며, 헤드라이너(13)의 단부는 필러 트림부재로부터 벗어나 차실측으로 휘어져 개방되며, 이에따라 차실내로 커튼형 에어백(15)이 전개되어지게 되는 것이다.In the present invention, when the sensor detects a collision of the vehicle, the inflating gas is rapidly inflated in the curtain-type airbag 15, and accordingly, the filler lamp member 16, which is a protective body, is opened to the notch 21 by a reference point. The end portion of the headliner 13 is bent away from the filler trim member to be opened to the compartment, and thus the curtain airbag 15 is deployed into the compartment.

그런데 이때 필러 램프부재(16)의 단부(16a)(16b)는 노치부(21)를 기준점으로 꺽어져 필러 트림부재(12)에 걸터앉아 커튼형 에어백(15)의 전개를 돕게되는 것이며, 필러 트림부재(16)가 펼쳐질 때 그의 슬릿홈(18)(18)을 브라켓트(17)(17)가 구속하여, 양측으로 흔들리거나 벗어남이 브라켓트(17)(17)의 구속에 의해 방지되어지게 되는 것이다.However, at this time, the end portions 16a and 16b of the filler lamp member 16 are bent at the notch portion 21 with reference points to sit on the filler trim member 12 to assist the deployment of the curtain airbag 15, and the filler When the trim member 16 is unfolded, the slit grooves 18 and 18 are restrained by the brackets 17 and 17 so that shaking or deviation from both sides is prevented by the restraint of the brackets 17 and 17. will be.

이상과 같은 본 발명은 필러 램프부재를 차체구조물에 직접 고정하지 아니하고 그의 상면 양단에 슬릿홈을 형성하고 브라켓트로 하여금 그 슬릿홈에 끼워져 지지되도록 하고,그 브라켓트를 볼트로써 차체바디에 고정하는 구조를 채택하므로써, 필러 램프부재의 양끝단의 슬릿홈내에 브라켓트가 삽입되어 지지하는 것에 의해 커튼형 에어백의 전개시 좌우로의 흔들림이 방지되어 안정적으로 에어백이 전개되며, 에어백 전개시 필러 램프부재가 필러 트림부재의 단부를 걸터타고 앉아 미끄럼틀과 같은 안내부재로서 기능하므로 필러 트림부재에 에어백이 걸려 전개 작동에 방해되는 일이 없게 된다.The present invention as described above forms a slit groove at both ends of the upper surface thereof without fixing the filler lamp member directly to the vehicle body structure so that the bracket is fitted into the slit groove to be supported, and the bracket is fixed to the body body by bolts. By adopting the bracket in the slit grooves at both ends of the filler lamp member, the lateral movement of the curtain airbag is prevented from lateral swinging and the airbag is stably deployed. By sitting on the end of the member to function as a guide member such as a slide, the airbag is caught by the filler trim member so that the deployment operation is not disturbed.
