摘要： Disclosed herein is a seat rail for vehicles. The seat rail of this invention eliminates gaps between a lower track and an upper track in horizontal and vertical directions, and distributes a load transmitted through the upper track, thus improving overall durability. The invention reduces the number of parts required, thus reducing the cost of a product and the working hours, realizing a light product, reducing fuel consumption, improving operational performance, reducing operational noise, and improving operating sensation. Further, the invention secures strength sufficient to support bending moment of the upper track, which is a concern during a head-on collision or a rear-end collision, thus maximizing the safety of passengers.
