Abstract

본 발명은 차량의 정면 충돌로 인한 관성력에 의해 운전자의 가슴부분이 받는 충격으로 인한 상해를 저감하기 위한 자동차용 스티어링 칼럼의 충격 흡수장치로 이를 실현하기 위하여 자동차의 충돌을 감지하는 충돌 감지센서와, 이 충돌 감지센서로부터 신호를 인지하여 에어백장치를 작동시키는 전자제어장치와, 이 전자제어 장치의 신호에 의해 개구작동하여 오일이 리저버 탱크로 리턴되도록 스티어링 칼럼의 오일챔버에 설치된 솔레노이드 밸브와, 이 솔레노이드 밸브의 개구에 의해 오일이 가압 배출되도록 하므로서 전달된 충격력을 흡수하도록 설치한 충격 완충장치를 포함하여 이루어지고 있다.The present invention relates to a shock absorber for a steering column of a vehicle for reducing an injury caused by an impact of a bicep of a driver due to an inertial force caused by a frontal collision of a vehicle, A solenoid valve installed in the oil chamber of the steering column so that the oil is returned to the reservoir tank by an opening operation by a signal of the electronic control unit, And a shock absorbing device provided so as to absorb the transmitted impact force by allowing the oil to be pressurized and discharged by the opening of the valve.
