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.

Spindle drive for longitudinally adjusting a motor vehicle seat

An adjusting means for adjusting two vehicle parts relative to each other, in particular for the longitudinal setting of a vehicle seat is provided. The adjusting means comprising an adjusting gear unit arranged on a first vehicle part and a spindle arranged on a second vehicle part, which extends in longitudinal direction, is in engagement with the adjusting gear unit and along which the adjusting gear unit is movable for adjusting the first vehicle part relative to the second vehicle part. There is provided a reinforcement part which supports the adjusting gear unit with respect to the first vehicle part in the longitudinal direction of the spindle such that due to the reinforcement part with forces introduced in the longitudinal direction from the first vehicle part into the adjusting gear unit the adjusting gear unit is supported with respect to the first vehicle part with a higher rigidity than with forces introduced against the longitudinal direction.
