한편, 에어백쿠션(30)은 팽창되면서 개방부(24)를 빠져나온 후 헤드라이너(40)를 밀어내고, 이로 인해 헤드라이너(40)는 차실내를 향해 벌어진다. 따라서, 헤드라이너(40)와 필라트림(50) 사이에 에어백쿠션(30)이 전개되는 틈이 형성되고, 에어백쿠션(30)은 헤드라이너(40)와 필라트림(50) 사이의 틈으로 빠져나와서 차실내의 도어와 탑승자 사이로 전개되어 탑승자를 보호할 수 있는 것이다.On the other hand, the airbag cushion 30 is pushed out of the open portion 24 while inflating the headliner 40, thereby causing the headliner 40 is opened toward the interior of the vehicle. Therefore, a gap is formed between the headliner 40 and the pillar trim 50, and the airbag cushion 30 is formed, and the airbag cushion 30 falls into the gap between the headliner 40 and the pillar trim 50. It will be deployed between the door and the occupants in the cabin to protect the occupants.

또한, 자동차의 충돌 사고시나 전복 사고시에 승객의 머리가 헤드라이너(40) 에 부딪치는 경우가 발생하는데, 이와 같이 탑승자의 머리가 헤드라이너(40)에 부딪치면 헤드라이너(40)가 탄성지지부(25)에 접촉되어 탄성지지부(25)를 밀게 되므로, 탄성지지부(25)가 수납부재(20)에 수납된 에어백쿠션(30)을 향해 오므라들어서 탑승자의 머리 충격을 흡수할 수 있다.In addition, when the head of the passenger hits the headliner 40 during a car crash or rollover accident, the headliner 40 is elastic support (when the head of the passenger hits the headliner 40 in this way) Since the elastic support 25 is pushed in contact with 25, the elastic support 25 may be retracted toward the airbag cushion 30 stored in the accommodation member 20 to absorb the head shock of the occupant.

도 4는 본 발명의 제2 실시예에 의한 커튼에어백 장치의 작동 전 상태를 도시한 단면도, 도 5는 본 발명의 제2 실시예에 의한 커튼에어백 장치의 작동 후 상태를 도시한 단면도, 도 6은 도 4 및 도 5에 도시된 수납부재의 사시도이다. 여기서는 전술한 실시예와 동일한 것에 대해서는 동일한 도면부호를 부여하여서 그에 대한 설명은 생략하고, 다른점만을 설명하기로 한다.Figure 4 is a cross-sectional view showing a state before the operation of the curtain airbag apparatus according to a second embodiment of the present invention, Figure 5 is a cross-sectional view showing a state after the operation of the curtain airbag device according to a second embodiment of the present invention, Figure 6 Is a perspective view of the housing member shown in FIGS. 4 and 5. Here, the same reference numerals are given to the same as the above-described embodiments, and description thereof will be omitted, and only differences will be described.

도 4 내지 도 6을 참조하면, 본 발명의 제2 실시예에 의한 커튼에어백 장치는 전술한 실시예와 다른점을 알 수 있다.4 to 6, it can be seen that the curtain airbag apparatus according to the second embodiment of the present invention is different from the above-described embodiment.

즉, 탄성지지부(25)에는, 탄성지지부(25)가 에어백쿠션(30)의 팽창력에 의해 벌어질 수 있도록, 보강리브(26)의 일부가 절개되어 노치부(28)가 형성된다.That is, a part of the reinforcing rib 26 is cut in the elastic support part 25 so that the elastic support part 25 can be opened by the expansion force of the airbag cushion 30, and the notch part 28 is formed.

자세히 설명하면, 에어백쿠션(30)에 가스가 유입되어 에어백쿠션(30)이 팽창되면 에어백쿠션(30)의 팽창력에 의해 탄성지지부(25)가 벌어지게 되는데, 이때 탄성지지부(25)는 노치부(28)의 양면이 서로 접촉될 때까지 벌어질 수 있다.In detail, when the gas is introduced into the airbag cushion 30 and the airbag cushion 30 is inflated, the elastic support 25 is opened by the expansion force of the airbag cushion 30, wherein the elastic support 25 is notched. It may be opened until both sides of 28 are in contact with each other.

한편, 탄성지지부(25)에는, 탄성지지부(25)의 벌어지는 각도를 제한하는 스토퍼(29)가 더 배치된다. 즉, 탄성지지부(25)는 상술한 바와 같이 노치부(28)의 양면이 서로 접촉될 때까지 벌어질 수도 있지만, 탄성지지부(25)가 에어백쿠션(30)의 팽창력에 의해 비틀어지면서 벌어질 경우에 노치부(28)의 양면은 서로 접촉하지 못 하게 되므로 탄성지지부(25)의 벌어지는 각도를 제어할 수 없게 된다. 따라서, 탄성지지부(25)에는 탄성지지부(25)가 에어백쿠션(30)의 팽창력에 의해 벌어질 때 노치부(28) 전면과 접촉되어 탄성지지부(25)의 벌어지는 각도를 제어할 수 있는 스토퍼(29)가 노치부(28)의 후면과 수평하게 배치된다.On the other hand, the stopper 29 which limits the opening angle of the elastic support part 25 is further arrange | positioned at the elastic support part 25. As shown in FIG. That is, the elastic support 25 may be opened until both sides of the notch 28 are in contact with each other, as described above, but when the elastic support 25 is twisted by the inflating force of the airbag cushion 30, the elastic support 25 is opened. Since both sides of the notch 28 are not in contact with each other, the opening angle of the elastic support 25 cannot be controlled. Therefore, when the elastic support portion 25 is opened by the inflating force of the airbag cushion 30, the elastic support portion 25 is in contact with the front surface of the notch portion 28 so as to control the opening angle of the elastic support portion 25 ( 29 is disposed horizontally with the rear surface of the notch 28.

스토퍼(29)는 노치부(28)의 전면과 수평하게 배치되어, 탄성지지부(25)가 벌어질 때 노치부(28)의 후면과 접촉되어서, 탄성지지부(25)의 벌어지는 각도를 제한할 수 있다. 본 실시예에서는 스토퍼(29)가 노치부(28)의 후면과 수평하게 배치되어, 탄성지지부(25)가 벌어질 때 노치부(28)의 전면과 접촉되어서, 탄성지지부(25)의 벌어지는 각도를 제한하는 것으로 예시하였다.The stopper 29 is disposed horizontally with the front surface of the notch portion 28, and when the elastic support portion 25 is opened, it is in contact with the rear surface of the notch portion 28, thereby limiting the opening angle of the elastic support portion 25 have. In this embodiment, the stopper 29 is disposed horizontally with the rear surface of the notch portion 28, and when the elastic support portion 25 is opened, the stopper 29 is in contact with the front surface of the notch portion 28, the opening angle of the elastic support portion 25 It is illustrated as limiting.

노치부(28)의 크기는, 수납부재(20)에 수납된 에어백쿠션(30)이 팽창되면서 개방부(24)로 빠져나온 후 탄성지지부(25)와 필라트림(50) 사이의 틈(C)에 걸리지 않게, 탄성지지부(25)가 에어백쿠션(30)을 가이드할 수 있도록, 탄성지지부(25)가 에어백쿠션(30)의 팽창력에 의해 적절하게 벌어질 수 있는 크기로 형성되는 것이 바람직하다.The size of the notch part 28 is the gap between the elastic support part 25 and the pillar trim 50 after exiting the opening part 24 while the airbag cushion 30 stored in the housing member 20 is expanded. It is preferable that the elastic support 25 is formed to a size that can be appropriately opened by the inflating force of the airbag cushion 30 so that the elastic support 25 can guide the airbag cushion 30 so as not to be caught. .

이와 같이 구성되는 경우에는, 탑승자의 머리가 헤드라이너(40)에 부딪치면 헤드라이너(40)가 탄성지지부(25)에 접촉되어 탄성지지부(25)를 밀게 되므로, 탄성지지부(25)가 노치부(28)를 중심으로 수납부재(20)에 수납된 에어백쿠션(30)을 향해 오므라들어서 탑승자의 머리 충격을 흡수할 수 있다.In such a configuration, when the head of the occupant hits the headliner 40, the headliner 40 contacts the elastic support 25 and pushes the elastic support 25, so that the elastic support 25 is notched. The airbag cushion 30 accommodated in the housing member 20 may be retracted around the 28 to absorb the head shock of the occupant.

상기와 같이 구성된 본 발명의 실시예에 의한 커튼에어백의 작용을 도 4 및 도 5를 참조하여 살펴보면 다음과 같다.Looking at the operation of the curtain airbag according to an embodiment of the present invention configured as described above with reference to Figures 4 and 5 as follows.

먼저, 자동차 사고가 발생되어 수납부재(20)에 수납된 에어백쿠션(30)으로 가스가 유입되면 에어백쿠션(30)은 팽창되기 시작하고, 이러한 에어백쿠션(30)의 팽창력에 의해 탄성지지부(25)가 노치부(28)를 중심으로 벌어지면서 개방부(24)의 크기가 커지게 되어, 에어백쿠션(30)은 개방부로 빠져나오면서 전개되기 시작한다.First, when a car accident occurs and gas flows into the airbag cushion 30 stored in the housing member 20, the airbag cushion 30 starts to expand, and the elastic support 25 is caused by the expansion force of the airbag cushion 30. As the center is opened about the notch 28, the size of the opening 24 is increased, and the airbag cushion 30 starts to unfold as it exits to the opening.

이때, 탄성지지부(25)는 노치부(28)의 양면이 접촉될 때까지 또는 노치부(28)의 전면이 스토퍼(29)에 접촉될 때가지 벌어져서 전개되는 에어백쿠션(30)을 가이드한다.At this time, the elastic support 25 guides the airbag cushion 30 that is opened until the both sides of the notch 28 are in contact or until the front surface of the notch 28 is in contact with the stopper 29.

에어백쿠션(30)은 탄성지지부(25)의 안내를 받으며 전개되면서, 탄성지지부(25)와 필라트림(50) 사이의 틈(C)에 걸리지 않고 계속 전개가 되며, 헤드라이너(40)를 밀어 내고 헤드라이너(40)와 필라트림(50) 사이의 틈으로 빠져나와서 도어와 탑승자의 사이로 전개되어 탑승자를 보호한다.The airbag cushion 30 is deployed while being guided by the elastic support 25, and continues to develop without being caught in the gap C between the elastic support 25 and the pillar trim 50, and pushes the headliner 40. It exits into the gap between the headliner 40 and the pillar trim 50 and is deployed between the door and the occupant to protect the occupant.

한편, 자동차의 충돌 사고시나 전복 사고시에 승객의 머리가 헤드라이너(40)에 부딪치면 헤드라이너(40)는 탄성지지부(25)에 접촉되어 탄성지지부(25)를 밀게되고, 이로 인해 탄성지지부(25)는 노치부(28)를 중심으로 수납부재(20)에 수납된 에어백쿠션(30)을 향해 오므라들어서 승객의 머리 충격을 흡수하게 된다.On the other hand, when the passenger's head hits the headliner 40 during a car crash or rollover accident, the headliner 40 is in contact with the elastic support 25 to push the elastic support 25, thereby causing the elastic support ( 25 is retracted toward the airbag cushion 30 accommodated in the receiving member 20 around the notch portion 28 to absorb the head shock of the passenger.

상기와 같이 본 발명의 실시예에 의한 커튼에어백 장치는, 에어백쿠션(30)이 접혀져서 수납되는 수납부재(20)의 일면이 개방되어, 에어백쿠션(30)을 용이하게 수납할 수 있을 뿐만 아니라 구조가 간단하여 에어백모듈의 중량 및 원가를 절감할 수 있다.As described above, in the curtain airbag device according to the embodiment of the present invention, one surface of the accommodation member 20 in which the airbag cushion 30 is folded and received is opened to easily receive the airbag cushion 30. Simple structure can reduce weight and cost of airbag module.
