Case parts of an adjustment mechanism for a seat adjustment device of a motor vehicle can be joined together along a parting line via joint surfaces. The joint surfaces are provided for the purpose of reciprocal placement of the case parts by way of a joining process. Contact surfaces of the case parts are present in addition to the joint surfaces The contact surfaces are in non-parallel alignment to the joint surfaces. Transferred gear forces running parallel to at least a section of the joint surfaces are absorbed by the contact surfaces. The case parts are fastened to one another by way of screw connections. The contact surfaces of the one case part are respectively held in position with respect to the contact surfaces of the other case part solely due to the screw connections. With such a case, high loads can be absorbed in spite of a small size.

Gear case of a seat adjusting drive for a motor vehicle

In a vehicle seat, in particular a motor vehicle seat, a sensor device () is arranged between the superstructure of the vehicle seat and the seat rail () of the vehicle seat, in order to measure forces transmitted from the superstructure into the seat rail (). The sensor device () can be positioned at least partially inside the seat rail ().

Sensor device for a vehicle seat

In a longitudinal adjuster for a vehicle seat, in particular for an automobile seat, for motor-driven longitudinal adjustment of the vehicle seat (), having a first seat rail () defining the longitudinal direction, a second seat rail () that can be made to slide relative to the first seat rail (), a first drive element () in the first seat rail (), and a second drive element () cooperating with the first drive element () to achieve longitudinal adjustment, the second drive element () being mounted in a drive casing () belonging to the second seat rail (), the drive casing () being mounted longitudinally between two bearing plates () connected to the second seat rail (), and each bearing plate () is firmly attached to the second seat rail () on at least two sides.

Longitudinal adjuster for a vehicle seat

In a longitudinal adjuster () for a vehicle seat, in particular a motor vehicle seat, having a first seat rail (), a second seat rail () that can be slid lengthwise relative to the first seat rail (), and at least one locking element () movably borne in the second seat rail (), reaching outward at least in certain areas through openings () of the second seat rail () and cooperating with notches () of the first seat rail () to lock the longitudinal adjuster (), at least one marginal layer (') of the locking element () is softer than a marginal area (&#x2032;) of the second seat rail () bordering the openings () and/or a marginal area of the first seat rail () bordering the notches ().

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.
