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 basic loading and the total loading that varies during operation of the adjusting apparatus.
