Abstract: In a longitudinal adjuster for a vehicle seat having a freely pivotable backrest, with the longitudinal adjuster having a first seat rail, a second seat rail, in relation to which the first seat rail can be slid in the longitudinal direction, and a memory device (11) which is assigned to the first seat rail, interacts with the second seat rail and stores a longitudinal seat position which can be left by means of a longitudinal displacement of the vehicle seat when the backrest pivots freely, and resumed when the backrest pivots back, a displacement measuring device (21), which can be operatively connected to the second seat rail, and a control signal generator (53), which can move in relation to the displacement measuring device (21), are provided for playing a role in resuming the stored longitudinal seat position.

Abstract: A seat part is supported at the upper rails of rail arrangements which are arranged at both longitudinal sides of the seat and which comprise, in addition to an upper rail, a lower rail which receives the upper rail in a longitudinally displaceable manner. A locking device which can be disengaged from a row of teeth of each lower rail for the purpose of longitudinal displacement of the seat is arranged at the upper rails. The locking device has a release device which is coupled with toothed arms at swivelably supported locking levers, which toothed arms are spring-loaded in the locking direction. The release device has a two-part release lever formed of a swivelably supported actuating lever and a grip bar or actuating stirrup.
