Abstract: A seat adjustment apparatus for adjusting seat elements of a seat in a motor vehicle comprises a gear mechanism housing of an electric motor/gear mechanism unit attached to a fitting part of a first seat element by an attachment element. A rotation movement can be transmitted to a rotation axis by the gear mechanism unit of the electric motor/gear mechanism unit. The attachment element can be attached to the gear mechanism housing by an end region and has an expansion plug part which projects through a recess in the fitting part, and has a passage opening axial to the recess in the fitting part and an identical cross section. An expansion element, which radially expands the expansion plug part, can be inserted into the passage opening.
