The present teachings relate to a neck fan for a vehicle seat for generating a usable air flow that emerges from the neck fan toward a passenger, said neck fan being provided with at least one air conveying device for generating a usable air flow in the region of a headrest or the upper end of a seat back. It is provided that one or more compensating means are provided, by means of which asymmetrical climatic conditions caused by interfering currents in the area surrounding a passenger can be compensated for, and that one or more compensating means act asymmetrically on the usable air flow and/or impart an asymmetry to the cross-section of the usable air flow, at least in the region of an outlet of the neck fan, said asymmetry relating to at least one geometric or thermodynamic parameter.
