Longitudinal seat-adjustment device and vehicle seat

Abstract

A longitudinal seat-adjustment device may have one rail arrangement having at least one rail pair and at least one locking element. The rail arrangement is formed from a top rail and a bottom rail, which are movable relative to one another. The at least one locking element is held in a spring-loaded and movable manner on the top rail and blocks a movement of the top rail in the bottom rail in a locking position and enables a movement in an unlocking position. An additional lock is provided, which interacts with the locking element in the locking position in such a way that a movement of the locking element in at least one spatial direction is limited or blocked. A vehicle seat having such a longitudinal seat-adjustment device is also provided.
