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.
