The present invention relates to a locking device for a seat rail of a vehicle, which comprises: a plurality of locking holes formed in a row rail fixed to the bottom of the vehicle in the front/rear direction of the vehicle; a locking pin assembly coupled to an upper rail movably coupled to the low rail to be able to vertically move and including a plurality of locking pins inserted into a part of the plurality of locking holes; an operation lever coupled to the upper rail and vertically moving the plurality of locking pins; and a reinforcement member fixed to the low rail and including a plurality of through-holes communicating with the plurality of locking holes, respectively. The reinforcement member has an extension hole extended from each of the plurality of through-holes. According to the present invention, even if the locking hole is deformed by the locking pin upon a collision of the vehicle, it is prevented that the locking pin is moved toward the front side of the vehicle by the reinforcement member, such that separation of the locking pin is prevented, thereby protecting a passenger from a bigger injury.

    본 발명은 차량용 시트레일의 록킹장치에 관한 것으로, 차량 바닥에 고정되는 로우레일에 차량의 전후 방향으로 형성되는 복수의 록킹홀과, 로우레일에 이동가능하게 결합되는 어퍼레일에 상하로 이동되도록 결합되며 복수의 록킹홀 중 일부에 끼워지는 복수의 록킹핀을 갖는 록킹핀 어셈블리와, 어퍼레일에 결합되며 복수의 록킹핀을 상하 이동시키는 작동레버와, 로우레일에 고정되며 복수의 록킹홀에 각각 연통되는 복수의 관통홀을 구비하는 보강부재를 포함하되, 보강부재는, 복수의 관통홀에 각각 연장되는 연장홀이 형성되는 것을 특징으로 하며, 차량의 충돌시 록킹핀에 의해 록킹홀이 변형되더라도 보강부재에 의해 록킹핀이 차량 전방 쪽으로 이동되는 것을 방지하여 이탈되는 것을 방지할 수 있어 승객을 더 큰 부상으로부터 보호할 수 있다.
