Claim:
A longitudinal adjuster for providing motor-driven longitudinal adjustment of a vehicle seat, the longitudinal adjuster comprising: a first seat rail extending in a longitudinal direction; a second seat rail mounted: for sliding relative to the first seat rail in the longitudinal direction, and so that a space is defined between the first seat rail and the second seat rail; a stationary spindle firmly attached to the first seat rail, wherein the spindle is positioned in the space defined between the first seat rail and the second seat rail; a drive element mounted in a drive casing for cooperating with the spindle to cause the second seat rail to slide relative to the first seat rail in the longitudinal direction; and two bearing plates which are spaced apart from one another in the longitudinal direction, wherein: for each of the bearing plates: there is firm attachment between the bearing plate and the second seat rail proximate at least two sides of the bearing plate so that the bearing plate moves with the second seat rail relative to the first seat rail in the longitudinal direction, and the firm attachment includes at least: a first engagement between the bearing plate and the second seat rail, with the first engagement being proximate a first of the two sides of the bearing plate, and a second engagement between the bearing plate and the second seat rail, with the second engagement being proximate a second of the two sides of the bearing plate, the drive casing is mounted between the two bearing plates so that the drive casing moves with the second seat rail relative to the first seat rail in the longitudinal direction, and the second seat rail includes a plurality of openings which are each discontinuous from one another and are respectively proximate to substantial parts of the bearing plates.
