To this end, the incision line 410 is preferably formed in the headlining 400 corresponding to the position on the center line of the occupant's head.

도 5는 본 발명의 일 실시예에 따른 차량용 사이드 커튼에어백장치의 에어백쿠션을 나타낸 도면이다.5 is a view showing an airbag cushion of the side curtain airbag apparatus for a vehicle according to an embodiment of the present invention.

도 5에 도시된 바와 같이, 탑승자 머리 양측방향으로의 에어백쿠션(200) 전개는, 한 쌍의 롤링쿠션(210)을 통해 구현된다. 이 한 쌍의 롤링쿠션(210)은 차량 충돌 시 시트(500)에 앉은 탑승자 머리의 양측방향으로 경사지게 전개되는 구조를 갖는다.As shown in FIG. 5, the deployment of the airbag cushion 200 in both directions of the occupant's head is implemented through a pair of rolling cushions 210. The pair of rolling cushion 210 has a structure that is inclined in both directions of the occupant's head sitting on the seat 500 when the vehicle crash.

즉, 한 쌍의 롤링쿠션(210)은 외측단부가 인플레이터(100)의 공급관(110)에 연결되고 내측단부가 탑승자 머리의 일측방향으로 전개되도록 권취된 일측 롤링쿠션(211)과, 외측단부가 인플레이터(100)의 공급관(110)에 연결되고 내측단부가 탑승자 머리의 타측방향으로 전개되도록 권취된 타측 롤링쿠션(212)으로 구성된다. 이때, 일측 롤링쿠션(211)의 내측단부는 내측 반시계방향으로 권취되고, 타측 롤링쿠션(212)의 내측단부는 내측 시계방향으로 권취된다.That is, the pair of rolling cushions 210 have one side rolling cushion 211 and an outer end of which the outer end is connected to the supply pipe 110 of the inflator 100 and the inner end is wound to be developed in one direction of the occupant's head. It is composed of the other rolling cushion 212 is connected to the supply pipe 110 of the inflator 100 and the inner end is wound to be deployed in the other direction of the occupant's head. At this time, the inner end of the one side rolling cushion 211 is wound in the inner counterclockwise direction, the inner end of the other rolling cushion 212 is wound in the inner clockwise direction.

따라서, 차량 측면 충돌시 인플레이터(100)의 가스가 롤링쿠션(210)에 공급되면, 일측 롤링쿠션(211)은 시트(500)에 앉은 탑승자 머리의 일측방향으로 전개되면서, 충격으로부터 탑승자의 일측방을 보호하고, 타측 롤링쿠션(212)은 시트(500) 에 앉은 탑승자 머리의 타측방향으로 전개되면서, 충격으로부터 탑승자의 타측방을 보호한다. 예를 들어, 탑승자가 운전석에 앉아 있는 경우, 일측 롤링쿠션(211)은 조수석의 탑승자로부터 운전석의 탑승자를 보호하고, 타측 롤링쿠션(212)은 차량 측면 충돌로 인한 직접적인 충격으로부터 운전석의 탑승자를 보호할 수 있다.Therefore, when the gas of the inflator 100 is supplied to the rolling cushion 210 during the vehicle side collision, the one side rolling cushion 211 is deployed in one direction of the occupant's head sitting on the seat 500, and the passenger's one side from the impact And the other rolling cushion 212 is deployed in the other direction of the occupant's head sitting on the seat 500, to protect the other side of the occupant from the impact. For example, when the occupant is sitting in the driver's seat, one side rolling cushion 211 protects the occupant of the driver's seat from the passenger seat, and the other rolling cushion 212 protects the occupant of the driver's seat from direct impact due to a vehicle side collision. can do.
