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.
