An air-guiding device for an interior of a motor vehicle includes a housing forming a cavity, slats accommodated in the cavity, and an outlet opening. The slats are formed pivotably in a direction of a body transverse axis and configured to deflect an air flow in the direction of the body transverse axis. The outlet opening enables the air flow to flow into the interior of the motor vehicle. The slats are arranged upstream of the outlet opening and spaced apart, for non-visibility, from the outlet opening in a direction of a body longitudinal axis. A central web is arranged in the cavity. The central web is configured to deflect the air flow in a direction of a motor vehicle vertical axis, and the central web divides the cavity in the direction of the motor vehicle vertical axis into a first flow duct and a second flow duct.
