Summary:PURPOSE: An impact-absorbing type steering system of a vehicle is provided to prevent driver's chest from being getting injured by moving a steering wheel away from a driver by the impact applied to the vehicle regardless the direction of the impact force applied to the steering wheel. CONSTITUTION: An impact-absorbing type steering system of a vehicle comprises an upper shaft(1) seated in an upper tube fixed to a dash board through a bracket and combined to a steering wheel; a lower shaft(2) seated in a lower tube to the dash board through the bracket and connected to a gearbox converting the rotational force of the steering wheel; and a moving unit disposed between the shafts. The moving unit generates gas by a working signal of an air bag and moves the upper shaft toward the lower shaft. Thus, the steering wheel is moved away from a driver and an injury in the driver's chest is prevented. 본 발명은 차량의 충격흡수형 조향시스템에 관한 것으로, 조향시스템의 조향휠로 가해지는 충격력의 방향에 관계없이 차량에 가해지는 일정 이상의 충격에 의해 조향휠을 운전자로부터 멀리 이동시켜 운전자의 가슴부상을 방지함에 그 목적이 있다. 상기와 같은 목적을 달성하기 위한 본 발명은, 대쉬보드 부위로 브라켓트(B)를 매개로 고정되는 어퍼튜브(RT)내로 수용되면서 조향휠에 결합된 어퍼샤프트(1)와, 대쉬보드 부위로 브라켓트(B)를 매개로 고정되는 로워튜브(LT)내로 수용되면서 조향휠의 회전력을 변환하는 기어박스로 연결된 로워샤프트(2) 및 이 샤프트(1,2)사이에 구비되어 에어백의 작동신호에 의해 가스를 발생시켜 상기 어퍼샤프트(1)를 로워샤프트(2)쪽으로 이동시키는 이동수단으로 이루어진 것을 특징으로 한다.
