Abstract

A ventilation duct (10) for a passenger interior of a motor vehicle has an inflow duct (12) for supplying air and a main guiding duct (14) that extends from the inflow duct (12) to an outlet opening (16) for guiding at least part of the air of the inflow duct (12) along a main flow direction (28) toward the outlet opening (16). At least one bypass duct (18, 40) can branch from the inflow duct (12) for discharging part of the air of the inflow duct (12). The bypass duct (18, 40) opens into the main guiding duct (14) upstream of the outlet opening (16) and introduces a flow jet (32) into the main guiding duct (14) at an angle to the main flow direction (28) for setting the flow direction of air at the outlet opening (16) without openings or louver grilles that are visible from the passenger interior.
