In a motor-vehicle seat a padding body of a cushion and/or backrest has a passage for air coming from an air conditioning system of the motor-vehicle. This passage includes a closed cavity defined between a lowered surface formed in an outer surface of the padding body and the seat cover. At least part of the closed cavity is separated from the cover through a layer of a material substantially impervious to air, configured to exchange heat by thermal conduction, through the cover with a body of an occupant.

1. A motor-vehicle seat, comprising: a seat cushion, anda seat backrest,wherein each of said seat cushion and seat backrest comprises: a padding body constituted of foamed plastic material, anda cover applied on said padding body,wherein in the padding body of at least one of said seat cushion and seat backrest is formed a passage for a flow of air coming from an air conditioning system of the motor-vehicle,wherein said passage for the air coming from the air conditioning system of the motor-vehicle comprises a cavity defined between said cover and a lowered surface portion formed in an outer surface of the padding body,wherein at least part of said cavity is separated from the cover through a layer of a material substantially impervious to air, adapted to exchange heat by thermal conduction through said cover, with a body of an occupant,wherein said layer of material substantially impervious to air covers a central portion of said lowered surface, and wherein said lowered surface includes lateral portions formed in lateral portions of said padding body on which said cover is applied with interposition of layers of a material pervious to air, so that part of the air flow supplied within said cavity comes out from the lateral portions of the seat through said layers of air-pervious material and through the cover, the latter being also of a material pervious to air, whereas at the central portion of the padding body said layer of material substantially impervious to air exchanges heat by thermal conduction, through said cover with the body of the occupant, andwherein said substantially air impervious layer has a plurality of holes for passage of air, for generating localized air jets. 2. The seat according to claim 1, wherein said lowered surface has a plurality of supporting projections and that on said projections there is supported a three dimensional mesh spacing fabric, having an outer layer constituting said layer of material substantially impervious to air. 3. The seat according to claim 2 wherein said layer of a material substantially impervious to air covers an entire extension of said lowered surface. 4. The seat according to claim 1, wherein: said cavity of the padding body is connected to the air conditioning system of the motor-vehicle by an air supply line which extends from the motor-vehicle air conditioning system to an outlet mouth located above a floor panel of the motor-vehicle and arranged under the motor-vehicle seat,said outlet mouth located above the motor-vehicle floor panel communicates with an air guiding line carried by the seat, which extends from an inlet mouth located under the seat to said cavity formed in the padding body,said outlet mouth located above the motor-vehicle floor panel and said inlet mouth located under the seat are in fluid communication with each other by an auxiliary connecting system which maintains said communication in different adjustment positions of the seat relative to the floor panel, both along longitudinal and vertical directions. 5. The seat according to claim 4, wherein said outlet mouth located above the motor-vehicle floor panel and said inlet mouth located under the seat are not mechanically connected with each other, said auxiliary connecting system comprising a suction hood device associated to the inlet mouth. 6. The seat according to claim 5, wherein said suction hood device comprises a closed casing with a lower wall facing the outlet mouth having two inlet apertures provided with respective suctions fans, said apertures being spaced from each other along the longitudinal direction of the motor-vehicle, to an extent such that at least one of these apertures is located in proximity of said outlet mouth in any position of the longitudinal adjustment of the seat. 7. The seat according to claim 6, wherein said outlet mouth is connected by a flexible and extendable duct to said inlet mouth and in that said inlet mouth is defined by a sleeve element movable longitudinally along a flat lower wall of a hollow casing, said sleeve element being associated with a wall in form of a roll-up shutter, slidably mounted along an endless path within said casing. 8. The seat according to claim 7, wherein said casing has an inner cavity separated by a longitudinal partition into two chambers arranged side by side which are respectively communicated to cavities formed in the padding body of the seat cushion and the seat backrest. 9. The seat according to claim 5, wherein said suction hood device has an opened lower side, facing said outlet mouth and having a longitudinal extension sufficient to have a portion thereof located above said outlet mouth in any position of the longitudinal adjustment of the seat, at least one suction fan being provided at one end of the suction hood device which is in communication with said cavity formed in the padding body of the seat.
