In a longitudinal adjuster () for a vehicle seat having a backrest that can pivot freely, a first seat rail (), and a second seat rail () relative to which the first seat rail () can be displaced longitudinally, a locking device () for locking the longitudinal adjuster (), a memory device assigned to the first seat rail () and interacting with the second seat rail (), said memory device memorizing a set longitudinal seat position which is relinquished when the vehicle seat () is longitudinally displaced during the free pivoting of the backrest () and is then re-assumed once the seat is displaced back again, and an actuation device () assigned to the first seat rail (), which actuation device actuates the resetting of the memory device and the unlocking of the locking device (), the actuation device () is arranged with limited movement capability in the longitudinal direction relative to the first seat rail ().

Longitudinal adjuster for a vehicle seat

A longitudinal adjuster for a vehicle seat includes a displacement sensor (), which can interact with a seat rail, and a control signal emitter (), which can be displaced in relation to the displacement sensor (). The relative movement of the signal emitter () in relation to the displacement sensor () reproducing, from a starting position, the longitudinal displacement carried out. The control signal emitter () is subjected to a control torque, at the latest once the stored longitudinal position of the seat has been reached, and then controls at least one blocking element () which interacts with the seat rail by way of a control spring (). A control bearing () is arranged between the control signal emitter () and the control spring (), which guides the control signal emitter () and which supports the control spring ().

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.

In a locking device for a vehicle seat, particularly a motor vehicle seat with a first component group ( ), having at least one locking element ( ) for interacting with a first seat rail ( ), being pretensioned and movably borne on a second seat rail ( ), and a second component group ( ) being movably borne relative to the first component group ( ) on the second seat rail ( ) and acting on the first component group ( ) when acted on by a manually operated unlocking element ( ), and control elements ( ) for controlling the unlocking process of the first component group ( ), the component groups ( ) are each rigid, and the control elements ( ) are arranged between the first component group ( ) and the second component group ( ).

Locking device for a vehicle seat

The invention relates to a longitudinal seat adjustment system for seats, comprising two pairs of rails ( ) which are set apart from each other. Said pairs of rails each consist of two U-shaped rails, an upper rail ( ) and a lower rail ( ). These two rails ( ) can be switched to a locking position or a release position by means of at least one spring-loaded, plate-shaped locking part ( ). Said locking part ( ) has teeth ( ) on two opposite sides, these teeth engaging in recesses ( ) or openings ( ) in the rails. According to the invention, the edge areas ( ) of the tooth-like recesses ( ) in the lower rail ( ) and/or the edge areas ( ) of the slit-like openings ( ) in the upper rail ( ) are permanently deformable. Consequently, in the locking position, the teeth ( ) of the plate-shaped locking part ( ) which engage in the openings ( ) and recesses ( ) deform the edge areas of said opening ( ) or recesses ( ) in the event of a considerable load, for example in an accident.
