Abstract: Adjustment fitting, in particular for a motor vehicle seat, having a first fitting part and having a second fitting part that is rotationally adjustable relative to the first fitting part about an axis of rotation, wherein the first fitting part has associated with it an outer wheel with internal teeth, in which wheel is inserted, in the manner of a wobble mechanism, an inner wheel with external teeth hat is associated with the second fitting part, and wherein the inner wheel forms a receiving space that is eccentric to the axis of rotation, and having an eccentric cam rotatably inserted in the eccentric receiving space, having a drive shaft for driving the eccentric cam. A central seal is placed in an axial gap between the two fitting parts.

Abstract: In order to reliably detect a jamming situation, in particular in a seat adjusting means, provision is made for a total loading exerted by the drive during a start phase to be determined and for this to be fixed as the basic loading. The existence or non-existence of a jamming situation is finally determined during a monitoring phase by comparing the gasinc loading and the total loading that varies during operation of the adjusting apparatus.
