摘要：
An actuating drive for a rail guide of a longitudinal adjustment of a motor vehicle seat has a rotational drive, which has an output shaft (70), and a transmission, which has a spindle nut (54), which is rotationally connected to the output shaft (70) and which has a spindle (52). The spindle (52) has a spindle thread, with which the spindle nut (54) is engaged. The spindle (52) is curved in a circular radius of curvature (42). The radius of curvature (42) is between 1,500 and 3,000 mm. The spindle nut (54) is a straight nut.
