Abstract

본 발명은 충돌에너지 흡수를 위한 니 볼스터구조에 관한 것으로, 인스트루먼트 패널(20)내에 타이 바(30)가 설치된 것에 있어서, 평면부(14)의 양측으로 측면부(15) 및 어깨부(16)를 대칭되게 형성시킨 단면구조를 갖고, 상기 인스트루먼트 패널(20)의 내부 전방에 설치된 타이 바(30)에 용접되는 선단부(11)와, 상기 선단부(11)로 부터 점차적으로 측면 폭이 좁아지면서 형성되는 굴곡부(12)와, 상기 인스트루먼트 패널(20)의 내측 보강판(22)에 고정수단(40)으로 부착되는 상기 굴곡부(12) 끝단의 후단부(13)로 구성되어 길이방향으로 “S”자 형상을 이루는 것을 특징으로 하는 충돌에너지 흡수를 위한 니 볼스터구조인 바, 본 발명에 의하면 충돌시 2차적으로 탑승자의 무릎이 인스트루먼트 패널에 부딪치게 되면 상기 니 볼스터가 좌굴되면서 인스트루먼트 패널이 밀려 들어가도록 하여 인체의 무릎에 가해지는 충돌력을 효과적으로 감소시킬 수 있게 되는 것이다.The present invention relates to a knee bolster structure for absorbing collision energy. In the case where the tie bar 30 is installed in the instrument panel 20, the side portions 15 and the shoulder portion 16 are disposed on both sides of the flat portion 14. It has a cross-sectional structure formed symmetrically, the front end portion 11 is welded to the tie bar 30 installed in the front of the inside of the instrument panel 20, and is formed while the side width gradually narrowed from the front end portion (11) The curved portion 12 and the rear end portion 13 of the end portion of the bent portion 12 which is attached to the inner reinforcing plate 22 of the instrument panel 20 by the fixing means 40, the letter "S" in the longitudinal direction According to the present invention, when the knee of the occupant collides with the instrument panel during collision, the instrument panel is buckled while the knee bolster is buckled. It will be able to effectively reduce the impact force applied to the knee of the human body.
