본 발명은 차량 도어용 임팩트패드에 관한 것으로, 특히 측면 충돌사고시 발생하는 충격력에 의해 급격하게 붕괴되는 현상을 없앨 수 있도록 하면서 충격흡수 성능도 향상시킬 수 있도록 구조를 개선한 차량 도어용 임팩트패드에 관한 것이다.The present invention relates to an impact pad for a vehicle door, and more particularly, to an impact pad for a vehicle door that has an improved structure to improve shock absorption while eliminating the phenomenon of sudden collapse by an impact force generated in a side collision accident. will be.

일반적으로, 차량의 바디(body)에는 탑승자의 승하차를 위해 힌지를 매개로 회전 개폐되는 도어가 장착되어 있는 바, 상기 도어의 구조는 도 1과 도 2에 도시된 바와 같다.In general, the body of the vehicle (bar) is equipped with a door that is rotated to open and close through the hinge for getting on and off the occupant, the structure of the door as shown in Figs.

즉, 차량의 도어(10)는 도시된 바와 같이 외측패널(11)과 내측패널(12) 및 도어트림(13)으로 구성되며, 상기 외측패널(11)과 내측패널(12)사이의 공간에는 도어(10)를 개폐를 위한 윈도우글래스(G)가 윈도우 레귤레이터(도시않됨)에 의해 승하강 작동이 가능하도록 구비된다.That is, the door 10 of the vehicle is composed of the outer panel 11, the inner panel 12 and the door trim 13, as shown in the space between the outer panel 11 and the inner panel 12 A window glass G for opening and closing the door 10 is provided to enable a lowering operation by a window regulator (not shown).

여기서, 상기 외측패널(11) 및 상기 내측패널(12)은 서로 중첩을 이룬 다수 군데가 상호 용접 결합됨으로써 하나의 도어 조립체를 형성하게 된다.Here, the outer panel 11 and the inner panel 12 are formed by welding a plurality of places overlapping each other to form a door assembly.

또한, 상기 도어트림(13)은 클립(C)과 같은 다수의 고정수단을 통해 상기 내측패널(12)에 고정되어 결합되는 구조이다.In addition, the door trim 13 has a structure that is fixed and coupled to the inner panel 12 through a plurality of fixing means such as a clip (C).

한편, 상기 도어(10)의 내부에는 임팩트바(20)와 임팩트쿠션(30)이 설치되는데, 상기 임팩트바(20)는 차체의 길이방향을 따라 설치되는 것으로서 측면 충돌시 발생한 충격력에 의해 도어(10)가 급격하게 붕괴되는 현상을 막을 수 있도록 부재가 지닌 자체의 강성으로 충격력을 저감시켜 탑승자의 안전을 확보할 수 있도록 된 것이다.On the other hand, the impact bar 20 and the impact cushion 30 is installed in the interior of the door 10, the impact bar 20 is installed along the longitudinal direction of the vehicle body by the impact force generated during the side impact ( In order to prevent the sudden collapse of 10), the member's own rigidity can reduce the impact force to ensure the safety of the occupants.

또한, 상기 임팩트쿠션(30)은 상기 인너패널(12)과 상기 도어트림(13)사이의 정해진 공간내에서 마운팅브라켓(31) 및 체결볼트(32)를 통해 상기 도어트림(13)에 고정 설치되거나 또는 테이프나 접착제와 같은 별도의 접착부재를 매개로 고정 설 치된다.In addition, the impact cushion 30 is fixedly installed on the door trim 13 through a mounting bracket 31 and a fastening bolt 32 within a predetermined space between the inner panel 12 and the door trim 13. Or fixedly installed via a separate adhesive member such as tape or adhesive.

상기 임팩트쿠션(30)은 블로우 성형에 의해 제작된 충격흡수부재로서, 상기 임팩트바(20)와 함께 측면 충돌시 발생한 충격력을 저감시켜 탑승자의 안전을 보호하게 된다.The impact cushion 30 is a shock absorbing member manufactured by blow molding, and protects the occupant's safety by reducing the impact force generated during side impact with the impact bar 20.

그러나, 통상적으로 사용되는 종래의 임팩트쿠션(30) 중 충격흡수성능의 향상에 중점을 둔 제품들은 자체적으로 보유한 강성이 충격력을 효과적으로 지탱할 수 있는 만큼 확보하지 못한 경우가 대부분이며, 이와 같은 경우 충격력에 의해 급격하게 붕괴됨으로써 탑승자의 부상이 커지게 되는 문제점이 있었다.However, among the conventional impact cushions 30, which are usually used, the products focused on the improvement of the shock absorbing performance are not secured as much as the rigidity possessed by itself can effectively support the impact force. There is a problem that the injury of the occupant is increased by a sudden collapse.

또한, 자체적인 강성에 중점을 두어 제작된 제품들은 반대로 충격흡수성능이 떨어지는 경우가 대부분이며, 이와 같은 경우에도 탑승자의 부상이 커지는 문제점이 발생하게 된다.In addition, products manufactured with a focus on its own rigidity are most often inferior in shock absorption performance, and even in this case, a problem of injuries of the occupants occurs.

이에 본 발명은 상기와 같은 모든 문제점들을 해소하기 위해 안출된 것으로서, 자체적으로 보유하는 강성 증대를 통해 측면충돌 사고시 발생하는 충격력을 효과적으로 지탱할 수 있게 하여 급격한 붕괴현상을 없앨 수 있도록 하고, 동시에 충격흡수성능도 향상시킬 수 있도록 구조를 개선하여 탑승자의 안전을 더욱 효과적으로 보호할 수 있도록 하는 차량 도어용 임팩트패드를 제공함에 그 목적이 있다.Accordingly, the present invention has been devised to solve all the above problems, and can effectively support the impact force generated in the event of a side collision by increasing the rigidity possessed by itself to eliminate the sudden collapse phenomenon, and at the same time the shock absorption performance An object of the present invention is to provide an impact pad for a vehicle door that can improve the structure so that the passenger's safety can be more effectively protected.

상기와 같은 목적을 달성하기 위한 본 발명의 임팩트패드는, 측면충돌시 붕괴되는 도어의 내측패널 및 도어트림과 접촉하는 패널접촉면과 트림접촉면을 구비하여 이루어지는 차량 도어용 임팩트패드에 있어서, 상기 패널접촉면에서 상기 트 림접촉면을 향해 오목한 모양으로 형성된 다수개의 패널측개구홈 및, 상기 트림접촉면에서 상기 패널접촉면을 향해 오목한 모양으로 형성되면서 상기 패널측개구홈과 각각 대칭구조를 갖도록 형성된 다수개의 트림측개구홈을 더 구비하여 이루어짐과 동시에; 상기 패널측개구홈과 상기 트림측개구홈사이의 내부공간은 속이 빈 챔버로 형성되는 한편; 상기 패널측개구홈과 상기 트림측개구홈은, 상기 패널접촉면과 상기 트림접촉면사이의 중간지점에서 서로 근접하게 이격되어 마주 대하는 바닥면과, 상기 바닥면에서 패널접촉면 및 트림접촉면까지를 각각 연결하는 경사진 둘레면을 구비하도록 형성된 것을 특징으로 한다.In the impact pad of the present invention for achieving the above object, the impact pad for a vehicle door comprising a panel contact surface and a trim contact surface in contact with the inner panel and the door trim of the door that collapses during side impact, the panel contact surface A plurality of panel side opening grooves formed in a concave shape toward the trim contact surface and a plurality of trim side openings each formed to have a symmetrical structure with the panel side opening grooves while being formed in a concave shape toward the panel contact surface at the trim contact surface. At the same time having a further groove; An inner space between the panel side opening groove and the trim side opening groove is formed as a hollow chamber; The panel side opening groove and the trim side opening groove are spaced apart from each other at an intermediate point between the panel contact surface and the trim contact surface to face each other, and to connect the panel contact surface and the trim contact surface, respectively, from the bottom surface. It is characterized in that it is formed to have an inclined peripheral surface.
