A ventilation device of a vehicle includes an air outflow opening disposed on an upper side of a backrest of a seat of the vehicle such that an airflow from the air outflow opening flows in a direction of a roof of the vehicle. A plurality of air guiding elements are pivotably mounted in a region of the air outflow opening where an air volume of a front partial airflow and a rear partial airflow is settable by the plurality of air guiding elements. A further air guiding element is disposed on the roof in a region of the airflow where the airflow is dividable and deflectable by the further air guiding element.
