Abstract: A spindle drive (10), with a spindle (20) which is rotatable about a rotation axis (24) at least indirectly by a drive motor (12), the spindle (20) having a thread-like spindle turn (22) on which a spindle nut (26) is arranged movably in the longitudinal direction of the rotation axis (24), and with a worm gear (15; 15a) which is arranged in a gear housing (14), is drivable by the drive motor (12) and is connected to the spindle (20) for conjoint rotation therewith.

Abstract: The invention relates to a spindle gearbox (1) of an electric seat drive, comprising a gearbox housing (2) for mounting a worm gear (3) and a worm, the worm meshing with the worm gear (3), a threaded spindle (4, 5) connected to the worm gear (3), a first lid (6), and a second lid (7), wherein the first lid (6) and the second lid (7) are fastened parallel to one another on the gearbox housing (2). The threaded spindle (4, 5) is guided through the first lid (6), and the first lid (6) is fastened on the gearbox housing (2) independently of the second lid (7).
