Abstract

본 발명은 자동차 도어(door)의 내부에 장착되는 임팩트바(impact)의 구조에 관한 것으로서, 측면부 충돌시 승원의 안전성이 향상되도록 하기 위해, 내측판넬( 11)과 외측판넬(12)이 소정의 공간을 두고 결합되는 도어 내부에, 일정폭의 평면으로 형성된 제1임팩트바(21)의 양단부가 취부되고, 상기 제1임팩트바(21)의 안쪽면에 도어 외측으로 개구되게 절곡되고 플랜지가 형성되는 제2임팩트바(22)가 플랜지에 의해 폐단면으로 결합되며, 상기 제1임팩트바(21)와 제2임팩트바(22)의 내부에 도어 외측으로 2중개구부가 형성되고 플랜지가 형성되는 제3임팩트바(23)가 상기 제1임팩트바(21)의 내측면에 플랜지가 결합되어, 차량의 측면부 충돌등의 사고로 외측판넬(12)이 파손되어 제1임팩트바(21)에 하중이 전달되면, 절곡 형성된 제2임팩트바(22)와 제3임팩트바(23)에 의해 하중이 도어의 내측판넬(11)쪽으로 분산되도록 하므로 제1임팩트바(21)의 중간부의 벤딩변형되는 것을 억제하고, 제1임팩트바( 21)에 의해 제3임팩트바(23)와 제2임팩트바(22)의 벌어짐이 억제되어, 외측판넬(12 )의 실내 침입을 효과적으로 억제하며, 다중으로 충격에너지를 흡수하도록 하는 자동차 도어의 임팩트바 구조이다.The present invention relates to the structure of an impact bar (impact) mounted in the interior of the car door (door), in order to improve the safety of the occupant during side impact, the inner panel 11 and the outer panel 12 is a predetermined Inside the door coupled to the space, both ends of the first impact bar 21 formed in a plane of a predetermined width is mounted, bent to open the outside of the door on the inner surface of the first impact bar 21 and a flange is formed The second impact bar 22 is coupled to the closed end surface by the flange, and the two intermediate openings are formed outside the door inside the first impact bar 21 and the second impact bar 22 and the flange is formed. The third impact bar 23 is flanged to the inner surface of the first impact bar 21, the outer panel 12 is damaged due to an accident such as a side portion of the vehicle, the load on the first impact bar 21 When this is transmitted, by the bent second impact bar 22 and the third impact bar 23 Since the load is distributed to the inner panel 11 of the door, the bending deformation of the middle portion of the first impact bar 21 is suppressed, and the third impact bar 23 and the second impact are affected by the first impact bar 21. Opening of the bar 22 is suppressed, effectively preventing the invasion of the interior of the outer panel 12, the impact bar structure of the automobile door to absorb the impact energy in multiple.
