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 ( ) 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 ( ), which can be operatively connected to the second seat rail, and a control signal generator ( ), which can move in relation to the displacement measuring device ( ), are provided for playing a role in resuming the stored longitudinal seat position.

Longitudinal adjuster for a vehicle seat

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. In order to prevent cancellation of the connection position between the locking lever supported at the upper rail and the row of teeth of the lower rail even when the release device is unintentionally actuated as the result of a collision by application of pressure to the grip bar or actuating stirrup in the rearward direction, the grip bar or the actuating stirrup is arranged so as to be displaceable longitudinally against the force of a spring element which positions the grip bar or actuating stirrup in the forward initial position and can be deflected to the rear when loaded by pressure acting toward the rear in the longitudinal direction of the seat.
