Claim:
1. A longitudinal adjustment device for a motor vehicle seat, comprising: two pairs of rails adjustable parallel to an x-axis; one locking device for each of the pairs of rails, which locking devices can each be moved to a release position to allow adjustment of the respective pair of rails; a handling mechanism; and a common actuating unit for the two locking devices that cooperates with the two locking devices, wherein the actuating unit comprises a housing, an electric drive motor, a gear unit connected to the electric drive motor, and an actuator connected to the gear unit, wherein the actuating unit is configured to exert a pulling force on each of the locking devices, wherein the housing is connected to one of the locking devices and the actuator is connected to the other locking device, wherein the force exerted on one of the locking devices is in an opposite direction to the force exerted on the other locking device, the actuating unit carries out a linear movement to exert such forces, the linear movement is parallel to a y-axis, and the linear movement extends over at least twice a distance required to move one of the locking devices to the release position, wherein the x-axis and the y-axis are perpendicular to each other, and wherein one of the locking devices reaches the release position before the other of the locking devices reaches the release position.
