According to the present invention, disclosed is a bicycle saddle lowering device. The saddle lowering device installed on a bicycle with a fixation lever to fixate a height position of a saddle is in a state that motion of a trigger member having elastic force in a direction towards the fixation lever is blocked by a stopper, and the bicycle is safely operated. When the bicycle is excessively suddenly stopped or collided during running, a stopping state of the trigger member is released when a rider directly presses an operation button or a sensor detects that a speed change is equal to or larger than a predetermined value. Thereby, the trigger member releases a lock state of the fixation lever while hitting the fixation lever and the saddle is lowered by a weight of the rider. Eventually, the center of gravity of the bicycle rider is moved downwards, so an accident is prevented.

    자전거 안장하강장치가 개시된다. 안장의 높낮이 위치를 고정시키는 고정레버를 구비한 자전거에 장착된 안장하강장치는 고정레버를 향하는 방향으로 탄성력을 가진 공이부재가 스토퍼에 의해 움직임을 저지당하고 있는 상태이며 자전거는 안전하게 운행하고 있다. 이 후 자전거가 주행 중 과도하게 급정거하거나 충돌하게 되면 탑승자가 직접 구동버튼을 누르거나 센서에 의해 속도 변화가 소정치 이상인 것으로 감지되는 것에 의해 공이부재의 스토핑 상태는 해제된다. 이에 의해 공이부재는 고정레버를 타격하면서 고정레버의 잠금상태를 해제하며 탑승자의 무게에 의해 안장이 하강된다. 결국 자전거의 탑승자의 무게중심이 아래로 이동하여 안전사고가 방지된다.
