This reduces the safety of the occupants.

즉, 본 발명에 따른 상기 임팩트패드(30)는 도 3과 도 4에 도시된 바와 같이, 도어(10)의 내측패널(12)에 결합되는 하판부재(31)와, 도어트림(13)에 결합되는 상판부재(32)와, 차체의 좌우방향으로 상기 하판부재(31)와 상기 상판부재(32)를 벌집구조로 연결하는 중간부재를 포함하여 구성된다.That is, the impact pad 30 according to the present invention has a lower plate member 31 coupled to the inner panel 12 of the door 10 and the door trim 13 as shown in FIGS. 3 and 4. The upper plate member 32 to be coupled, and the intermediate member for connecting the lower plate member 31 and the upper plate member 32 in a honeycomb structure in the left and right directions of the vehicle body.

여기서, 상기 중간부재는, 상기 하판부재(31)와 상기 상판부재(32) 사이의 공간을 차체의 좌우방향을 따라 다수개로 분할하도록 상기 하판부재(31) 및 상기 상판부재(32)와 평행하게 배치되는 평판형상의 격판부재(33)와, 상기 하판부재(31)와 격판부재(33) 및 상기 격판부재(33)와 격판부재(33) 그리고 상기 상판부재(32)와 격판부재(33)를 연결하도록 설치되는 물결모양으로 형성된 다수개의 연결부재(34)로 구성된다.Here, the intermediate member is parallel to the lower plate member 31 and the upper plate member 32 to divide the space between the lower plate member 31 and the upper plate member 32 into a plurality in the left and right directions of the vehicle body. The flat plate member 33, the lower plate member 31 and the plate member 33, the plate member 33 and the plate member 33 and the upper plate member 32 and the plate member 33 are arranged Consists of a plurality of connecting members 34 formed in the shape of a wave installed to connect the.

상기와 같은 구성으로 된 본 발명의 임팩트패드(30)는, 상기 하판부재(31)와 연결부재(34) 및 상기 격판부재(33)와 연결부재(34) 그리고 상기 상판부재(32)와 연결부재(34) 사이에 다수개의 충격흡수공간(35)이 형성된 구조를 갖는다.Impact pad 30 of the present invention having the configuration as described above, the lower plate member 31 and the connection member 34 and the diaphragm member 33 and the connection member 34 and the upper plate member 32 is connected A plurality of shock absorbing spaces 35 are formed between the members 34.

상기 연결부재(34)는 물결모양이 차체의 전후방향을 향하도록 설치된다.The connecting member 34 is installed so that the wave shape faces the front and rear direction of the vehicle body.

한편, 상기 하판부재(31)와 상기 상판부재(32) 그리고 상기 격판부재(33)와 상기 연결부재(34)는 모두 압축페이퍼로 형성된다.On the other hand, the lower plate member 31 and the upper plate member 32 and the diaphragm member 33 and the connection member 34 are all formed of compressed paper.

이와 같이, 압축페이퍼로 형성되면 경량화를 도모할 수 있게 되므로 연비향상에 도움이 되고, 또한 충분한 강성확보가 가능한 장점이 있게 되므로 측면 충돌 사고시 발생한 충격력에 의해 임팩트패드(30)가 급격히 붕괴되는 현상이 방지되어 탑승자의 안전을 더욱 효과적으로 보호할 수 있게 된다.As such, when the compression paper is formed, it is possible to reduce the weight, so that it is helpful to improve fuel efficiency, and also has the advantage that sufficient rigidity can be secured, so that the impact pad 30 collapses rapidly due to the impact force generated during the side collision accident. This can prevent the passenger's safety more effectively.

상기 격판부재(33)의 두께(T3)는 상기 상판부재(32)에서 상기 하판부재(31)쪽으로 갈수록 점차 두껍게 형성되고, 상기 상판부재(32)의 두께(T2)는 가장 두껍게 형성된 상기 격판부재(33)의 두께(T3)보다 더 두껍게 형성되며, 상기 하판부재(31)의 두께(T1)는 상기 상판부재(32)의 두께(T2)보다 더 두껍게 형성된 구조를 갖는다.The thickness T3 of the diaphragm member 33 is gradually increased from the upper plate member 32 toward the lower plate member 31, and the thickness T2 of the upper plate member 32 is the diaphragm formed thickest. It is formed thicker than the thickness T3 of 33, the thickness T1 of the lower plate member 31 has a structure formed thicker than the thickness T2 of the upper plate member (32).

즉, 상기 하판부재(31)는 측면 충돌 사고시 충격력을 가장 먼저 전달받는 부위이기 때문에 두께(T1)를 가장 두껍게 하여 충분한 강성을 확보하도록 하고, 이를 통해 임팩트패드(30)의 급격한 붕괴현상을 예방하도록 한다.That is, since the lower plate member 31 is a portion that receives the impact force first when a side collision occurs, the thickness T1 is thickest to secure sufficient rigidity, thereby preventing the sudden collapse of the impact pad 30. do.

그리고, 상기 격판부재(33)가 상기 상판부재(32)에서 상기 하판부재(31)쪽으로 갈수록 두께(T3)가 점차 두껍게 형성되는 이유는, 강성 확보에 서로 차이를 둠으로써 상기 격판부재(33)가 충격력을 흡수하면서 순차적으로 붕괴될 수 있도록 하기 위함이며, 이를 통해 탑승자의 안전을 보다 효과적으로 보호할 수 있도록 하기 위함이다.The reason why the thickness T3 is gradually increased as the diaphragm member 33 moves from the upper plate member 32 toward the lower plate member 31 is different from each other to secure rigidity. In order to be able to collapse sequentially while absorbing the impact force, and to thereby more effectively protect the safety of the occupants.

또한, 상기 상판부재(32)는 충격력을 가장 나중에 전달받는 부위이면서 탑승자와 가장 근접한 위치에 설치되는 부위이기 때문에 최종적으로 전달된 충격력을 충분히 견딜 수 있도록 하기 위해, 가장 두껍게 형성된 상기 격판부재(33)의 두께(T3)보다 두께(T2)를 더 두껍게 형성하였다.In addition, since the upper plate member 32 is a portion that receives the impact force lastly and is installed at the position closest to the occupant, the plate member 33 formed thickest to sufficiently endure the impact force finally delivered. The thickness T2 was formed thicker than the thickness T3 of.

그리고, 상기 하판부재(31)와 격판부재(33) 및 상기 격판부재(33)와 격판부 재(33) 그리고 상기 상판부재(32)와 격판부재(33) 사이의 간격(L1)은 상기 상판부재(32)에서 상기 하판부재(31)쪽으로 갈수록 점차 증가하도록 형성되고, 상기 충격흡수공간(35)의 단면적(A1)은 상기 상판부재(32)에서 상기 하판부재(31)쪽으로 갈수록 점차 증가하도록 형성된 구조를 갖는다.The lower plate member 31 and the diaphragm member 33, the diaphragm member 33 and the diaphragm member 33, and the gap L1 between the upper plate member 32 and the diaphragm member 33 are the upper plate. The member 32 is formed to gradually increase toward the lower plate member 31, and the cross-sectional area A1 of the shock absorbing space 35 increases gradually toward the lower plate member 31 from the upper plate member 32. Has a formed structure.

이에 따라, 본 발명의 임팩트패드(30)는 측면 충돌 사고시 발생한 충격력에 의해 상판부재(31)에서 하판부재(32)쪽으로 순차적으로 붕괴되면서 충격력을 충분히 흡수할 수 있게 됨으로써, 탑승자를 보다 더 안전하게 보호할 수 있는 장점이 있다.Accordingly, the impact pad 30 of the present invention is capable of absorbing the impact force sufficiently while being sequentially collapsed from the upper plate member 31 to the lower plate member 32 by the impact force generated during the side collision accident, thereby protecting the occupant more safely. There is an advantage to this.

이상 설명한 본 발명에 따른 임팩트패드(30)는 강성이 충분히 확보된 구성일 뿐만 아니라 충격력을 순차적으로 충분히 흡수할 수 있는 구조이기 때문에, 측면 충돌 사고시 발생한 충격력에 의해 형상이 급격하게 붕괴되는 현상이 없어지게 되고, 또한 보다 향상된 충격흡수성능을 통해 탑승자의 안전을 더욱 안정적으로 보호할 수 있는 장점이 있다.Impact pad 30 according to the present invention described above is not only a structure that is sufficiently secured rigidity, but also a structure capable of absorbing the impact force sufficiently in sequence, there is no phenomenon that the shape is suddenly collapsed by the impact force generated during the side collision accident In addition, there is an advantage that can more stably protect the safety of the occupant through improved shock absorption performance.
