이하에서는 상기 범퍼 빔(2), 범퍼 스테이(3), 범퍼 커버(4), 에너지 압소버 (5)를 포함한 플라스틱제 범퍼와, 강판제 범퍼인 ㄷ형 범퍼본체를 범퍼 시스템(10)이라 칭한다.Hereinafter, the plastic bumper including the bumper beam 2, the bumper stay 3, the bumper cover 4, and the energy absorber 5, and the c-shaped bumper body, which is a steel plate bumper, are referred to as a bumper system 10.

11은 고정부재로서, 상기 고정부재(11)는 강판을 박스형으로 형성하여 상기 사이드 멤버(1)에 볼트로 체결하거나 용접 등으로 결합한 것이다.11 is a fixing member, and the fixing member 11 is formed by forming a steel plate in a box shape and fastening the bolt to the side member 1 by a bolt or by welding.

12는 하부 범퍼수단으로서, 상기 하부 범퍼수단(12)은 상기 고정부재(11)에 원형 또는 4각단면의 지지부재(13)를 스프링 지지판(14)과 함께 수평으로 결합하고, 상기 지지부재(13)에 코일 스프링(15)을 내장함과 동시에 완충부재(16)를 슬라이딩 할 수 있게 설치하며, 상기 완충부재(16)의 선단은 범퍼 커버(4)에 접촉 은폐되게 한 것이다.12 is a lower bumper means, and the lower bumper means 12 horizontally couples the support member 13 of the circular or quadrangular cross section with the spring support plate 14 to the fixing member 11, and the support member ( The coil spring 15 is embedded in the 13 and installed to slide the shock absorbing member 16. The tip of the shock absorbing member 16 is concealed in contact with the bumper cover 4.

상기 완충부재(16)는 지지바(26)와 상기 지지바(26)에 설치하는 발포 또는 비발포 플라스틱 또는 고무 등으로 된 완충봉(27)으로 구성하고, 상기 지지바(26)에 안내공(28)을 형성하여 지지부재(13)에 핀(29)으로 슬라이딩 할 수 있게 지지한 것이다.The buffer member 16 is composed of a support bar 26 and a buffer rod 27 made of foamed or non-foamed plastic or rubber installed on the support bar 26, and guide holes on the support bar 26. Formed by 28 to support the sliding member to the support member 13 to the pin 29.

이상과 같은 본 발명은 차량과 차량이 충돌하였을 때에는 기존의 강판제 또는 플라스틱제 범퍼에 의하여 충돌 에너지를 흡수하고, 차량과 보행자가 충돌할 경우에는 보행자의 대퇴부가 먼저 기존의 범퍼에 충돌되고 보행자의 대퇴부가 기존의 범퍼에 충돌되면 다리가 차량 측으로 진입되면서 다리가 완충부재(16)에 충돌되는 바, 상기와 같이 다리가 완충부재(16)에 충돌되면 완충봉(27)에서 충돌 에너지를 흡수함과 동시에 다리가 차량 측으로 진입되는 것이 억제되고 다리부위보다 중량이 무거운 상반신이 굽혀짐으로서 다리부의 상해치가 경감되는 것이다.In the present invention as described above, when the vehicle collides with the vehicle, collision energy is absorbed by the existing steel plate or plastic bumper, and when the vehicle collides with the pedestrian, the thigh of the pedestrian first collides with the existing bumper, When the thigh collides with the existing bumper, the leg enters the vehicle side and the leg collides with the shock absorbing member 16. As described above, when the leg collides with the shock absorbing member 16, the shock absorbing rod 27 absorbs the collision energy. At the same time, it is suppressed that the leg enters the vehicle side, and the injured value of the leg portion is reduced by bending the upper body, which is heavier than the leg portion.

상기와 같이 다리가 차량 측으로 진입되는 것이 억제될 때 그 충돌 에너지가 클 경우에는 완충부재(16)가 안내공(28)에 안내되면서 고정부재(11) 측으로 슬라이딩하고 완충부재(16)가 고정부재 측으로 슬라이딩할 때 지지부재(13)에 내장된 코일 스프링(15)이 탄성 변형하면서 재차 충돌 에너지를 흡수함으로서 다리의 상해치를 더욱 더 경감함과 동시에 무릎 골절을 예방할 수 있는 것이다.When the collision energy is large when the leg is prevented from entering the vehicle as described above, the shock absorbing member 16 is guided to the guide hole 28 and slides toward the fixing member 11, and the shock absorbing member 16 is fixed. When the coil spring 15 embedded in the support member 13 is elastically deformed when sliding to the side, absorbing the collision energy again, it is possible to further reduce the injury of the leg and at the same time prevent knee fracture.

상기한 실시예에서는 플라스틱제 범퍼를 적용한 차량에 대하여 설명하였으나 본 발명은 강판제 범퍼를 적용한 차량에 대하여도 적용할 수 있으며, 이 경우에는 ㄷ형 범퍼본체가 범퍼 커버의 대응 구성요소로서 기능을 하고, 고정부재는 프레임에 결합하는 것이다.In the above embodiment, but described with respect to the vehicle to which the plastic bumper is applied, the present invention can be applied to the vehicle to which the steel plate bumper is applied, in which case the c-shaped bumper body functions as a corresponding component of the bumper cover, The fixing member is to be coupled to the frame.

이상과 같이 본 발명은 기존의 범퍼 시스템을 적용한 차량의 차체의 하부에 하부 범퍼수단을 결합하여 탑승자의 다리부위에 가하여지는 충돌 에너지를 흡수하였음으로 탑승자의 다리부위의 상해치를 경감하고, 무릎 골절을 예방할 수 있는 것이다.As described above, the present invention combines the lower bumper means to the lower part of the vehicle body to which the existing bumper system is applied, thereby absorbing the collision energy applied to the leg portion of the occupant, thereby reducing the injury of the leg portion of the occupant, and reducing the knee fracture. It can be prevented.
