본 발명은 자동차 도어 임팩트바(Impact Bar)의 완충구조에 관한 것으로서, 특히 자동차 도어의 내측에 구비된 임팩트바에 충격완충구조를 형성하여 견고하게 함으로써, 측면 충동시 도어에 가해진 충격을 감소시켜 차내 승차자의 안전을 확보하고 차체의 파손을 최소로 줄이기 위한 자동차 도어 임팩트바의 완충구조에 관한 것이다.The present invention relates to a shock absorbing structure of an automobile impact bar, and in particular, to form a shock-absorbing structure in the impact bar provided inside the automobile door, thereby making it firm, thereby reducing the impact applied to the door during side impacts. This invention relates to a shock absorbing structure of an automobile impact bar for securing safety and minimizing damage to the vehicle body.

일반적으로 자동차 도어의 임팩트바란, 자동차 도어의 보강 및 지지장치의 하나로 자동차의 도어 내부에 설치되어 자동차의 도어를 지지하고, 측면 충돌시 도어의 가해진 충격을 완충시키는 역할을 하는 것이다.In general, the impact bar of the car door is one of the reinforcement and support devices for the car door, which is installed inside the door of the car to support the door of the car, and serves to cushion the impact of the door during side impact.

이와 같은 자동차 도어 임팩트바의 구조는 제3도에 도시된 바와 같이 도어(10)의 내측패널(12) 양측에 설치된 브라켓(13)에 임팩트바(20)를 장착시키고, 상기 임팩트바(20)와 도어(10)의 외측패널(11) 내측면 사이에는 충진재(30)를 개재시키도록 구성된다.As shown in FIG. 3, the impact bar 20 is mounted on the bracket 13 installed on both sides of the inner panel 12 of the door 10, and the impact bar 20. And the filler 30 is interposed between the inner surface of the outer panel 11 of the door 10.

이와 같이 구성된 종래 자동차 도어 임팩트바는 도어(10)의 외측패널(11)과 임팩트바(20) 사이에 충진재(30)를 개재하여 자동차의 측면 충돌시 도어(10)에 가해지는 충격을 충진재(30)가 흡수하여 완충시킨후 임팩트바(20)로 전달된다.Conventional vehicle door impact bar configured as described above is filled with the impact applied to the door 10 during the side impact of the vehicle through the filler 30 between the outer panel 11 and the impact bar 20 of the door 10 ( 30 is absorbed and buffered and then delivered to the impact bar 20.

그러나 임팩트바(20)의 형상이 단수한 파이프(Pipe) 형태로 형성되어 있어 자체의 내충격성 및 내굴절성의 취약하여 충격으로부터 도어(10)를 충분히 보지 못하고, 임팩트바(20) 자체가 약간의 충격에도 굴절 등의 변형 및 파손이 발생하게 된다.However, since the impact bar 20 is formed in the shape of a simple pipe, its impact resistance and refractive resistance are weak, so that the door 10 is not sufficiently seen from the impact, and the impact bar 20 itself is slightly Deformation and damage such as refraction occur even in the impact.

상기와 같은 임팩트바(20)는 자체의 내충격성 및 내굴절성 등의 완충구조가 전혀없이 단순히 지지하고 있는 상태이므로 차량의 측면 충돌시 도어(10)에 가해진 외부충격을 효과적으로 지탱하지 못하고 쉽게 변형되어 충격이 감소되지 않은 상태에서 차 내부로 전달될뿐 아니라, 자체의 파손정도가 심하게 된다.Since the impact bar 20 is simply supported without any shock absorbing structure such as its impact resistance and refractive resistance, the impact bar 20 does not effectively support the external impact applied to the door 10 during side impact of the vehicle and is easily deformed. Not only is it transmitted to the inside of the car in a state where the impact is not reduced, but also the degree of damage itself is severe.

그러므로 차내의 승차자가 충돌시 약간의 충격에도 부상 또는 더 위험한 상태에 이르게 되는 등의 문제점이 있다.Therefore, there is a problem that the occupant in the car leads to an injury or a more dangerous state even with a slight impact during a collision.

한편 상기와 같은 문제점으로 해결하기 위한 것으로, 제4도에 도시된 바와 같은 임팩트바의 또다른 형태가 있으나 외측패널(11)에 밀착된 임팩트바(20)의 형태가 수직면을 갖고 후면으로 돌출된 부분이 있으나 이 역시 임팩트바(20) 자체의 신축 등의 변화없이 단순히 임팩트바(20)의 내구성만을 향상하고 내굴절성을 강화하지 못하여 충격을 효과적으로 흡수하지 못해 기존의 임팩트바와 동일한 문제점이 발생되고 있다.On the other hand to solve the problem as described above, there is another form of the impact bar as shown in Figure 4 but the shape of the impact bar 20 in close contact with the outer panel 11 has a vertical surface protruding to the rear Although there is a part, this also improves the durability of the impact bar 20 without changing the expansion and contraction of the impact bar 20 itself, and does not effectively absorb shock because it does not strengthen the refractive resistance, and the same problem occurs as the existing impact bar. have.

따라서, 본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로서, 자동차의 도어 내측에 구비된 임팩트바를 충격을 흡수 및 완충시킬 수 있도록 형성하여 내충격성 및 내굴절성을 강화함에 따라 차량의 측면 충돌시 도어의 파손을 최소로 줄일뿐 아니라, 차체의 파손과 차내 승차자의 안전을 확보하기 위한 자동차 도어 임팩트바의 완충구조를 제공하는데 있다.Accordingly, an object of the present invention is to devise to solve the conventional problems as described above, by forming an impact bar provided inside the door of the vehicle to absorb and cushion the impact to strengthen the impact resistance and refractive resistance In addition to minimizing the damage to the door in the event of a side collision of the vehicle, it provides a shock absorbing structure of the car door impact bar to ensure the damage of the vehicle body and the safety of the occupant in the car.
