The present invention relates to a side sill assembly of a vehicle including a side sill reinforcement material with improved crash performance, which prevents the side sill reinforcement material from being dislodged and pushed against the side sill within the side sill even when an impact load is input in the longitudinal direction of the vehicle. The side sill assembly of a vehicle including a side sill reinforcement material with improved crash performance according to the present invention is a side sill assembly in which a side sill reinforcement material (40) having a circumference formed with a closed cross-section and having upper and lower ribs (43) formed inside in the height direction of the vehicle is fastened to a side sill inner (31) and a side sill outer (32), wherein a support part (43a) supported by being in contact with a side surface of a support member (52) to which a fastening member (51) is fastened is formed on the upper and lower ribs (43), and the support member (52) to which the fastening member (51) for fastening the side sill reinforcement material (40) and the side sill (30) is fastened is fitted to be in contact with the support part (43a).

    본 발명은 차량의 길이방향으로 충격에 의한 하중이 입력되더라도 사이드실 보강재가 사이드실 내부에서 상기 사이드실에 대하여 이탈되어 밀리지 않도록 한 충돌성능이 향상된 사이드실 보강재를 포함하는 차량의 사이드실 어셈블리에 관한 것이다. 본 발명에 따른 충돌성능이 향상된 사이드실 보강재를 포함하는 차량의 사이드실 어셈블리는, 폐단면으로 둘레가 형성되어 그 내부에 차량의 높이방향으로 상하리브(43)가 형성되는 사이드실 보강재(40)가 사이드실 인너(31)와 사이드실 아우터(32) 체결되는 사이드실 어셈블리에 있어서, 체결부재(51)가 체결되는 지지부재(52)의 측면에 접하여 지지되는 지지부(43a)가 상기 상하리브(43)에 형성되고, 상기 사이드실 보강재(40)와 사이드실(30)의 체결을 위한 체결부재(51)가 체결되는 상기 지지부재(52)는 상기 지지부(43a)에 접하도록 끼워지는 것을 특징으로 한다.
