Abstract
Official abstract text for this publication.
A spindle drive for longitudinally adjusting a motor vehicle seat is provided. The spindle drive comprising an adjustment rail that can be longitudinally adjusted relative to a body mounted rail and an adjusting mechanism that includes a driving worm connected to a driving device as well as a spindle nut, the external teeth of which mesh with the external teeth of the driving worm, and the internal teeth of which mesh with the external thread of a spindle. The spindle nut is formed by a hybrid spindle nut that has a functional part, which is located in the force flux between the driving worm and the spindle, and at least one strengthening part, deflecting crash forces from the adjustment rail into the spindle.
