The invention relates to the technical field of automobile seats, and discloses a C-shaped arc sliding groove and double-roller concealed seat leg support which comprises a seat cushion framework, a synchronous rod and the like, a left metal plate support and a rivet are riveted into an assembly and then welded to the seat cushion framework, and a right metal plate support and a rivet are riveted into an assembly and then welded to the seat cushion framework. The middle metal plate bracket is welded with the seat cushion framework; the large roller and the small roller are assembled on the rivet; the left limiting strip and the right limiting strip are assembled to the middle metal plate support. The motor is assembled on the seat cushion framework through a first screw. According to the concealed seat leg support with the C-shaped arc sliding grooves and the double rollers, the C-shaped arc sliding grooves and the double rollers are adopted, the problem that the leg support shakes up and down and left and right during operation can be solved, and the concealed seat leg support is simple in process, convenient to assemble and low in cost; the large plastic part is divided into the three plastic parts, the three plastic parts are connected through the screws, and the problem that the large plastic part cannot be subjected to mold stripping in the process is solved.
