The invention discloses a motor vehicle seat lifting device and relates to the technical field of automobile components. The motor vehicle seat lifting device comprises a rotating arm axle tube mounted between two cushion frame side plates as well as a torsion rod, wherein two ends of the rotating arm axle tube are hinged with one corresponding rotating arm, one end of the torsion rod is mounted in the rotating arm axle tube, and the other end of the torsion rod is buckled above the rotating arms; limiting parts are arranged inside one end of the rotating arm axle tube, the bending part of the torsion rod is inserted into the rotating arm axle tube to be clamped with the limiting parts; the limiting parts adopt two limited blocks shaped like Chinese character 'ji' and having opposite openings, a plurality of small holes are formed in one end of the rotating arm axle tube, and the two limited blocks are welded in one end of the rotating arm axle tube after the angle is adjusted. The problems that the upper and lower parts of a seat lifting rack cannot rotate flexibly and accurately, the production process is complicated, the cost is high and the seat lifting and rotating torque is not uniform due to the fact that the torsion rod can be connected and limited in the steel tube only when the connecting part of the steel tube is pressed to be flat can be solved.
