Abstract

A height adjustment mechanism for a vehicle seat includes an adjustment parallelogram. The adjustment parallelogram includes a seat frame part, an upper rail and lateral links connecting the seat frame part and the upper rail. A spindle drive can adjust the adjustment parallelogram such that a distance between the seat frame part and the upper rail is changed by changing a length of the spindle drive. The spindle drive connects two obliquely opposing corners of the adjustment parallelogram (1) together in a reinforcing manner.
