본 발명은 자동차의 도어(door)에 취부되는 임팩트바(impact bar)에 관한것으로서, 특히 임팩트바에 패드를 부가시켜, 측면부 충돌시 충격으로부터 승원의 안전성이 향상되도록 하는 자동차 도어용 임팩트바의 패드 취부구조에 관한 것이다.The present invention relates to an impact bar mounted on a door of an automobile. In particular, by adding a pad to the impact bar, the pad mounting of the impact bar for an automobile door improves the safety of the occupant from impact during side impact. It's about structure.

종래 자동차 도어용 임팩트바의 취부구조는, 제1도와 제2도에 도시되는 바와 같이 내측판넬(11)과 외측판넬(12)이 절곡되어 소정의 공간을 형성하는 결합되고, 내측 공간 양측부에 각기 정션(junction)(13)이 용접에 의해 내측판넬(11)에 부착되고, 양쪽의 정션(13)에 중공의 환봉으로 된 임팩트바(impact bar)(20)의 양단부가 지지되어, 차량의 측면부 충돌등의 사고로 외측판넬(12)가 파손되는 경우, 임팩트바(20)가 파손된 외측판넬(12)의 진입을 억제하고 충격에너지를 흡수하여, 실내에 승차한 승원이 보호되도록 되어있다.The mounting structure of the impact bar for a conventional automobile door is combined with the inner panel 11 and the outer panel 12 bent to form a predetermined space, as shown in FIG. 1 and FIG. Junctions 13 are attached to the inner panel 11 by welding, and both ends 13 are supported at both ends of an impact bar 20 made of hollow round bars. When the outer panel 12 is damaged due to an accident such as a side part collision, the impact bar 20 suppresses the entry of the damaged outer panel 12, absorbs the impact energy, and protects the occupant in the room. .

그러나, 이러한 종래 자동차 도어용 임팩트바의 취부구조는, 차량의 측면부 충돌로 외측판넬(12)과 함께 임팩트바(20)가 파손되는 경우, 강체인 임팩트바(20)가 승원에 충격을 전달하게 되어 있기 때문에, 승원이 전달받는 충격이 비교적 크게 되어 승원의 안전이 위협되는 문제점이 있었다.However, such a conventional mounting structure of the impact bar for a car door is such that when the impact bar 20 is damaged along with the outer panel 12 due to the side impact of the vehicle, the rigid impact bar 20 transmits an impact to the occupant. Since the impact that the crew receives is relatively large, there is a problem that the safety of the crew is threatened.

본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위해, 승원의 측부에 위치되는 임팩트바의 일단부 외주면에 상하 양쪽으로 연장되는 브라켓이 취부되고, 상기 브라켓의 상하 양단부에 패드가 취부되어, 임팩트바가 승원에게 충격을 전달하게 되는 경우, 상기 패드에 의해 충격이 완충되도록 하는 자동차 도어용 임팩트바의 패드 취부구조를 제공하는 데 있다.An object of the present invention is to solve the conventional problems as described above, a bracket extending up and down on both sides of the outer peripheral surface of the end of the impact bar located on the side of the occupant is mounted, the pad is attached to the upper and lower ends of the bracket, When the impact bar is to deliver an impact to the occupant, to provide a pad mounting structure of the impact bar for the vehicle door to cushion the impact by the pad.

이하 첨부된 도면에 의하여 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.

본 발명의 도어도 제3도와 제4도에 도시되는 바와 같이 내측판넬(11)과 외측판넬(12)이 절곡되어 소정의 공간을 두고 결합되고, 내측 공간 양측부에 각기 정션(13)이 취부되고 양쪽의 정션(13)에 중공의 환봉으로 되는 임팩트바(impact bar)(20)의 양단부가 지지된다. 단, 본 발명은 실내의 승원이 위치하는 부위인 임팩트바(20)의 후단부 외주면에 소정폭을 가지고 상하방향으로 연장되는 브라켓(31)이 취부되어, 브라켓(31)의 상단과 하단부에 각기 완충용 패드(30)가 취부됨을 그 기술적 구성상의 기본 특징으로 한다.3 and 4, the inner panel 11 and the outer panel 12 are bent and joined to a predetermined space, and the junctions 13 are mounted on both sides of the inner space. And both ends of an impact bar 20 which are hollow round bars at both junctions 13 are supported. However, in the present invention, the bracket 31 extending in the vertical direction with a predetermined width is mounted on the outer circumferential surface of the rear end of the impact bar 20, which is the site where the occupant is located, and the upper and lower ends of the bracket 31 are respectively provided. It is a basic feature of the technical configuration that the shock absorbing pad 30 is mounted.

여기에서, 브라켓(31)은 중간부가 일정 반경을 가지는 곡면으로 형성되는 제1브라켓과 제2브라켓이 임팩트바(20)의 후단부 외주면에서 용접에 의해 결합되고, 제1브라켓의 상단부와 하단부에 각기 강판(33)이 볼트(32)에 의해 체결되어, 강판(33)의 외측면이 외측판넬(12)에 부착되고, 강판(33)의 내측면에 패드(30)가 취부된다.Here, the bracket 31 is the first bracket and the second bracket is formed in a curved surface having a predetermined radius in the middle portion is joined by welding on the outer peripheral surface of the rear end of the impact bar 20, the upper end and the lower end of the first bracket Each steel plate 33 is fastened by the bolt 32, the outer surface of the steel plate 33 is attached to the outer panel 12, the pad 30 is mounted on the inner surface of the steel plate 33.

이와 같이 구성되는 본 발명은, 차량의 측면부에 충격하중이 작용되어 외측판넬(12)가 파손되는 경우, 임팩트바(20)가 충격에너지를 흡수하고, 일정 이상의 충격하중으로 인해 임팩트바(20)가 파손되는 경우, 승원의 착좌위치에서 설치된 패드(30)가 내측판넬(11)를 통해 승원에게 전달되는 충격을 완충하도록 한다.According to the present invention configured as described above, when the impact load is applied to the side surface of the vehicle and the outer panel 12 is damaged, the impact bar 20 absorbs the impact energy, and the impact bar 20 due to the predetermined or more impact load. If is broken, the pad 30 installed in the seating position of the crew to cushion the shock transmitted to the crew through the inner panel (11).

이러한 본 발명은 임팩트바(20)가 외측판넬(12)를 통해 전달되는 외부의 충격에너지를 흡수하고, 충격하중이 일정이상이 되어 임팩트바(20)가 파손되는 경우, 패드(30)에 의해 승원에게 전달되는 충격이 저감되도록 하므로, 승원의 안전성이 향상되도록 하는 효과가 있다.In the present invention, the impact bar 20 absorbs the external impact energy transmitted through the outer panel 12, and the impact bar 20 is damaged by the pad 30 when the impact bar 20 is damaged by a predetermined or more. Since the impact delivered to the occupant is reduced, there is an effect that the safety of the occupant is improved.

이상에서 살펴본 바와 같이, 본 발명은 임팩트바에 취부되는 패드가 승원의 측부에 위치되어, 임팩트바가 승원과의 충격접촉시 승원에게 전달되는 충격이 저감되도록 하는 매우 유용한 것이다.As described above, the present invention is very useful that the pad is mounted on the impact bar is located on the side of the occupant, so that the impact transmitted to the occupant when the impact bar is in contact with the occupant is reduced.
