Claim:
A vehicle seat, comprising: at least one passage for heating or conditioning air; deviating means associated to the seat to control a flow of air through said at least one passage, wherein said deviating means includes at least one deviating device operating by Coanda effect; wherein said deviating device includes a main inlet duct, at least two secondary ducts that branch off the main duct, and a Coanda effect control member, associated with at least one wall of the inlet duct and displaceable between a first position, in which the flow from the inlet duct adheres due to the Coanda effect to a wall of the inlet duct that extends into a wall of a first of said secondary ducts, whereby the flow of air is deviated into said first secondary duct, and a second position, in which the flow detaches from said wall and adheres, due to the Coanda effect, to an opposite wall of the inlet duct that extends into a wall of the second secondary duct, in such a way that the flow is deviated into said second secondary duct; and wherein said at least one passage includes a plurality of grooves formed in an upper surface of a body of a padding of a cushion of the seat, immediately adjacent to a cover of the padding, each of said plurality of grooves communicating at upstream ends thereof with said inlet duct and communicating at downstream ends thereof with a discharge duct inside the seat or associated to the seat, in such a manner that the flow of air through said plurality of grooves performs a flushing function of an area of the seat configured to contact a user's body, without substantially passing through the cover of the seat.
