  • Patent number: 10195963
    Abstract: A longitudinal adjuster (3), for a vehicle seat (1), includes a lower rail (9), an upper rail (11), moveable in relation to the lower rail (9) in a longitudinal direction (x), and a locking unit (13) for locking the upper rail (11) to the lower rail (9). The locking unit (13) includes two locking elements (VR), which, in order to lock the upper rail (11) and the lower rail (9), engage in the upper rail and the lower rail in a blocking manner in steps such that one of the locking elements (VR) pre-locks the upper rail (11) and the lower rail (9) with play in a pre-locking step and one of the locking elements (VR) locks the upper rail (11) and the lower rail (9) without play in a locking step. A vehicle seat (1) including such a longitudinal adjuster (3) is provided.

  • Patent number: 9963049
    Abstract: A rail pair (1), for a vehicle seat (10), includes at least a lower seat rail (S1) and an upper seat rail (S2), which engage around one another in such a way that a rail profile is formed and which can be moved in relation to each other in a longitudinal direction (L) and can be interlocked by a rail locking device (2). Rolling elements (4) are arranged between the seat rails (S1, S2) in an interaction region. The upper seat rail (S2) includes two side walls (S2.1, S2.2), which two side walls (S2.1, S2.2), in a vertical orientation, protrude largely in parallel and perpendicularly from a bottom region (S2.3). One of the side walls (S2.2) is bent outward in a continued course in some regions of the longitudinal direction (L).
