본 발명은 커튼 에어백용 루프레일 사이드부 구조에 관한 것으로, 더 상세하게는 루프레일사이드인너와 헤드라이닝 사이에 설치되는 커튼에어백을 견고히 지지함과 동시에, 상기 커튼에어백이 설치되어 있는 헤드라이닝에 차실에 탑승한 승원의 머리등과 같은 신체가 접촉하는 경우에도 효과적으로 충격에너지가 흡수되도록 발명된 것이다.The present invention relates to a roof rail side part structure for a curtain air bag, and more particularly, to firmly support a curtain air bag installed between the roof rail side inner and the headlining, and to the head lining in which the curtain air bag is installed. Even when the body such as the head of the occupant in contact with the body is invented so that the impact energy is effectively absorbed.

종래 커튼 에어백용 루프레일 사이드부 구조는 도 1과 도 2 및 도 3에 도시하고 있는 바와 같이, 필러(미도시)에 용착된 루프레일사이드인너(120')의 양쪽 선단면에 루프패널(150')의 선단면이 용착되어 있는 사이드아우터패널(110')이 폐단면을 형성하며 용착되고, 상기 루프레일사이드인너(120')의 전후부에는 전방부 어시스트핸들브라켓(400')과 후방부 어시스트핸들브라켓(400')의 일단이 각각 용착되어있다.As shown in FIGS. 1, 2, and 3, the roof rail side part structure of the conventional curtain airbag includes a roof panel 150 formed at both front end surfaces of the roof rail side inner 120 ′ welded to a filler (not shown). A side outer panel 110 'on which the front end surface of') is welded is welded to form a closed end surface, and the front assist handle bracket 400 'and the rear part are formed at the front and rear portions of the roof rail side inner 120'. One end of the assist handle bracket 400 'is welded, respectively.

한편, 상기 전방부 어시스트핸들브라켓(400')과 후방부 어시스트핸들브라켓(400')의 후단부와 선단부에는 프리모션헤드폼리브(600')의 양단이 각각 별도의 체 결부재에 의해 결합되며, 상기 프리모션헤드폼리브(600')가 결합되어 있는 전방부 어시스트핸들브라켓(400')과 후방부 어시스트핸들브라켓(400')에는 헤드라이닝(200')을 관통하며 삽입된 각각의 어시스트핸들(500')의 체결부(510')가 끼워져 고정되며, 상기 어시트핸들브라켓(400')이 용착되어 있는 루프레일사이드인너(120')와 헤드라이닝(200') 사이에는 커튼에어백(300')이 설치되어 있다.On the other hand, both ends of the pre-motion head form rib 600 'are coupled to the rear end and the front end of the front assist handle bracket 400' and the rear assist handle bracket 400 'by separate fastening members, respectively. Each of the assist handles penetrating through the headlining 200 'is inserted into the front assist handle bracket 400' and the rear assist handle bracket 400 'to which the free motion head form rib 600' is coupled. The fastening part 510 'of the 500' is fitted into the curtain airbag 300 between the roof rail side inner 120 'and the headlining 200' on which the seat handle bracket 400 'is welded. ') Is installed.

이러한 종래 커튼 에어백용 루프레일 사이드부 구조는 차실에 탑승한 승원이 어시스트핸들브라켓(400')에 체결부(510')가 끼워져 결합되어 있는 어시스트핸들(500')을 손쉽게 이용할 수 있게 됨은 물론, 상기 어시스트핸들(500')이 설치되어 있는 루프레일 사이드부에 승원의 신체가 부딪히는 경우에는 헤드라이닝(200')에 내장되어 있는 프리모션헤드폼리브(600')가 탑승자에게 가해지는 충격을 완충시켜 주고 있다.The roof rail side part structure for the conventional curtain airbag can easily use the assist handle 500 'in which the occupant in the cabin is fitted with the fastening part 510' fitted to the assist handle bracket 400 '. When the body of the occupant hits the roof rail side portion where the assist handle 500 'is installed, the shock absorbed by the pre-motion head form rib 600' built in the headlining 200 'is absorbed. I'm letting you.

한편, 차량을 운행중 측면으로 추돌사고등이 발생하는 경우에는 커튼에어백(300')이 전개되면서 차실에 탑승한 승원이 부상당하는 것을 억제시키고 있다. On the other hand, if a collision accident or the like occurs while driving the vehicle, the curtain airbag 300 'is deployed to suppress the injuries of the occupants in the cabin.

그러나 이러한 종래 커튼 에어백용 루프레일 사이드부 구조는 차량을 조립시 루프레일의 사이드부 전후부에 각각의 전방부 어시스트핸들브라켓(400')과 후방부 어시스트핸들브라켓(400')의 일측부를 루프레일사이드인너(120')에 용착시킨 상태에서 커튼에어백(300')에 처짐이 발생하지 않도록 함과 동시에 차실에 탑승한 승원의 머리등과 같은 신체가 헤드라이닝(200')에 접촉하는 경우에는 충격을 흡수하면서 부상당하지 않도록 하는 별물의 프리모션헤드폼리브(600')의 양측단부를 각각 전방부 어시스트핸들브라켓(400')과 후방부 어시스트핸들브라켓(400')의 전후부에 각각 체결부재를 이용해 결합시켜야 함으로써, 차량을 조립시 부품수가 증가하고 작업량이 증가하여 조립성이 저하되는 문제점이 있었다.However, the roof rail side part structure for the conventional curtain airbag has one side of each of the front assist handle bracket 400 'and the rear assist handle bracket 400' at the front and rear sides of the roof rail when assembling the vehicle. In the state where the curtain air bag 300 'is welded to the side inner 120', the sagging of the curtain airbag 300 'does not occur, and the body such as the head of the crew in the cabin touches the headlining 200'. Fastening members on both sides of the front motion handle bracket 400 'and the rear assist handle bracket 400' respectively at both ends of the free motion head form rib 600 'to prevent injury from being absorbed. By using the combination, there is a problem in that the number of parts when assembling the vehicle and the amount of work is increased to reduce the assembly.

또한, 종래에는 상기 헤드라이닝(200')과 루프레일사이드인너(120') 사이에 설치되어 있는 커튼에어백(300')이 추돌사고 등에 의해 전개 시, 상기 커튼에어백(300')을 지지하고 있는 프리모션헤드폼리브(600')가 파손되면서 발생된 파편이 차실로 유입되어 차실에 탄승한 승원의 신체와 접촉하는 것에 의해 부상을 입게되는 문제점이 있었다. In addition, when the curtain airbag 300 'installed between the headlining 200' and the roof rail side inner 120 'is conventionally deployed by a collision or the like, the curtain airbag 300' is supported. There was a problem that the debris generated while the free motion head form rib (600 ') is broken into the car compartment and injured by contact with the body of the occupant riding the car.
