Abstract

본 발명은 자동차 도어용 임팩트바의 구조에 관한 것으로서, 차량의 내부로 승원이 승하차 하도록 하는 도어(40)의 내측공간부(45)에 충격에너지를 흡수하도록 하는 임팩트바(20)가 취부되는 것에 있어서, 상기 임팩트바(20)가 속이 빈 사각형상으로 형성되고, 상기 사각형상의 임팩트바(20)의 좌우 양측단부는 절곡되어 플랜지(25)가 형성되며, 상기 플랜지(25)는 도어(40)의 내측판넬(50)의 양측부에 취부하여, 사각형상으로 이루어진 좌우 양측단부가 플랜지(25)되는 것에 의해 폐단면(26)이 형성된 임팩트바(20)를 내측판넬(50)과 외측판넬(60)이 소정의 간격을 두고 결합되는 도어(40)의 공간부에 위치 시킨 후, 상기 내측판넬(50)의 양측면에 임팩트바(20)의 플랜지(25)가 용접에 의해 취부되어 도어(40)에 충격하중이 작용되는 경우, 외측판넬(60)을 통하여 내측으로 작용되는 충격하중이 임팩트바(20)의 폐단면(26) 내부에서 폭넓게 확산 되도록 하는 자동차 도어용 임팩트바의 구조이다.The present invention relates to a structure of an impact bar for an automobile door, wherein an impact bar (20) for absorbing impact energy is installed in an inner space (45) of a door (40) to allow an occupant to get in and out of a vehicle. In this case, the impact bar 20 is formed in a hollow rectangular shape, the left and right both ends of the rectangular impact bar 20 is bent to form a flange 25, the flange 25 is the door 40 Attached to both sides of the inner panel 50 of the inner side, the left and right both ends of the rectangular shape of the flange 25, the impact bar 20 having a closed end surface 26 is formed into the inner panel 50 and the outer panel ( 60 is located in the space portion of the door 40 coupled at predetermined intervals, and then the flange 25 of the impact bar 20 is mounted on both sides of the inner panel 50 by welding, so that the door 40 When an impact load is applied), the inner side is moved inwardly through the outer panel 60. The impact bar used is a structure of the impact bar for an automobile door so that the impact bar 20 can be widely spread within the closed end surface 26 of the impact bar 20.
