본 발명은 커튼에어백 보호쿠션의 파손방지구조에 관한 것으로서, 더욱 상세하게는 사고시에 승객의 머리부가 심각한 상해를 입지 않도록 보호하는 커튼에어백 보호쿠션의 외측에 가스가 차지 않는 프로텍터를 대어 보호쿠션의 전개시 도어 글라스 파편이나, 차체나 트림의 예리한 파편이 직접 보호쿠션에 닿는 것을 방지하는 커튼에어백 보호쿠션의 파손방지구조에 관한 것이다.The present invention relates to a breakage prevention structure of a curtain airbag protection cushion, and more particularly, to protect the head of a passenger from serious injury during an accident, by applying a protector that does not occupy gas on the outside of the curtain airbag protection cushion. The present invention relates to a breakage prevention structure of a curtain airbag protection cushion, which prevents the door glass fragments or the sharp pieces of the car body or the trim from directly contacting the protection cushion.

일반적으로 차량용 에어백 시스템은 일정 크기 이상의 충돌사고 발생시 에어백을 풍선처럼 부풀게 함으로써 에어백의 쿠션 작용에 의해 승객의 충격을 완화하고 승객이 차체 밖으로 튕겨 나가는 것을 방지하는 안전장치로서, 정면 충돌 시 앞좌석 승객을 보호하는 운전석 에어백(Driver Air-Bag, DAB) 및 조수석 에어백(Passenger Air-Bag, PAB) 등이 있다.In general, a vehicle airbag system is a safety device that mitigates a passenger's shock by cushioning the airbag and prevents the passenger from being thrown out of the vehicle body by inflating the airbag like a balloon in the event of a crash of a certain size or more. Driver Air-Bag (DAB) and Passenger Air-Bag (PAB).

그런데 근래에 들어서는 상기와 같은 에어백에 의한 탑승자 보호효과를 극대화하고자 시트의 좌우측면이나 루프사이드레일에도 에어백을 설치하여 측방향 충돌의 충격에 대해서도 탑승자를 보호할 수 있도록 되어 있다.However, in recent years, in order to maximize the protection effect of the occupants by the airbag as described above, airbags are installed on the left and right sides or the roofside rails of the seat to protect the occupants against the impact of the lateral collision.

이중 상기 루프사이드레일에 설치된 에어백을 커튼에어백(curtain air bag, CAB)이라 칭하는데, 이는 상기 에어백이 루프사이드레일로부터 하방으로 완전 전개되었을 때 도어 글라스를 가리게 되므로 마치 창문에 설치되는 커튼과 같은 형상을 취하는 것에 기인한 것이다.The airbag installed in the roofside rail is called a curtain air bag (CAB), which covers a door glass when the airbag is fully deployed downward from the roofside rail. It is due to taking.

상기한 커튼에어백(CAB)의 전개 원리는 차량의 측면 차체에 측면 충돌 가속도를 감지하는 측면충돌감지센서와 에어백 시스템을 제어하면서 오전개를 방지하기 위한 에어백 컨트롤 유닛에서 일정한 가속도값 이상을 인식하면 에어백을 전개한다.The principle of the deployment of the curtain airbag (CAB) is that the airbag control unit and the airbag system detect the side collision acceleration on the side body of the vehicle and control the airbag when the airbag control unit detects a certain acceleration value or more. Deploy

이러한 커튼에어백은 운전석, 조수석 쪽에 프런트필라에서 리어필라까지 장착되어 전석과 후석의 승객 모두를 보호하며, 특히 측면충돌이나 전복사고시 전개되어 승객의 머리부가 심각한 상해를 입지 않도록 보호한다.These curtain airbags are mounted from the front pillars to the rear pillars on the driver's and front passenger's sides to protect both passengers in the front and rear seats, and especially in the event of side collisions or rollovers to protect the passengers' heads from serious injury.

도 1a와 도 1b는 종래 커튼에어백 보호쿠션의 고정구조와 보호쿠션 전개시의 도면이다.Figures 1a and 1b is a view of the conventional structure of the curtain airbag protection cushion and the deployment of the protection cushion.
