Abstract
A vehicle seat comprises at least one passage for a heating or conditioning air flow and a flow deviating device associated to the seat to control the flow of air through such passage. The flow deviating device comprises at least one Coanda effect deviating device. In the case of application to the front seat of a car, the passage internal to the seat for the ventilation air flow has an upstream end communicating with an air supplying duct, and a downstream end communicating with a discharge duct whose outlet opens at the rear of the seat, to ventilate the rear part of the car passenger compartment. Said passage inside the seat is formed on the surface of the seat padding in the area of contact with the user's body, immediately below the cover of the padding. The discharge duct is arranged such that the flow of air through the passage carries out a flushing action of the area of contact with the user's body and is not forced to flow substantially through the cover.
