A closure or grille airflow shutter system, particularly for a motor vehicle includes a first shutter featuring at least one first adjustable shutter element with a first adjustment travel between a first and a second position. A second shutter features at least one second adjustable shutter element with a second adjustment travel between a first and a second position. A shutter coupling couples the first and the second shutters to one another in such a way that the second shutter element is not adjusted or adjusted over a first section of the second adjustment travel, which is smaller than the first section of the first adjustment travel, during an adjustment of the first shutter element over a first section of the first adjustment travel and adjusted over a second section of the second adjustment travel during an adjustment of the first shutter element over a second section of the first adjustment travel.
