Abstract: A support with a lumbar adjuster device for a motor vehicle seat includes a front side which, in the installed position, faces a seat user's back and a lumbar adjuster device which is arranged on the front side of the support and is intended for setting the position of the lumbar support perpendicular to the plane of extent of the backrest frame. The lumbar adjuster device has at least one adjuster element to be brought into operative connection with the lumbar support, and at least one slide which is movable with respect to the adjuster element. The slide can be moved, firstly, along a tensioning direction along which it is pretensioned, and, secondly, along a drawing direction along which a drawing force can be transmitted to the slide via a drawing means coupled to the slide.

Abstract: A motor vehicle seat system, control arrangement, actuating arrangement, and process are used to control a lumbar support device of a motor vehicle seat. The lumbar adjustment device has a first drive for adjustment in a first adjustment direction and a second drive for adjustment in a second adjustment direction. The adjustment directions differ from each other. A first adjustment position is ascertained in the first adjustment direction and the drive movement of the second drive is controlled as a function of at least one of the first adjustment position and the temporal change in the first adjustment position.

Abstract: A motor seat device includes a drive device for displacing a part of the seat in a particular direction. Data for operating the drive device in reaction to a presetting process is stored in a pre-setting memory. A memory drive device controls the drive device according to this operating data. The drive device is further controlled by having a control mechanism process the operating data issued from the drive device during its inertia rotation. The drive device is elastically coupled to the displaceable part so that an at least temporarily asynchronous movement can occur between the drive device and the displaceable part. The position of the displaceable part is determined by evaluating a signal generated by a drive movement of the drive device. The torque of the drive device or a parameter correlating thereto is evaluated to correct a position error caused by the asynchronous movement.

Abstract: According to the invention, the position of a part of a motor vehicle seat which can be displaced by a drive device (M1-M4) is determined by evaluating a signal (H1-H4) which is generated according to a drive movement of the drive device. In addition to this signal, at least one parameter is evaluated in order to correct a position error caused by at least temporarily asynchronous movements of the drive device and the displaceable part.
