<p>The foam body (2) has a porous covering (3) in the resting- or contact area (4). A first flexible shell (7) opposite this area includes cavities (8) across the foam body. A second flexible shell (9) is sealed below the first, and includes a housing (10) sealing with the fan (11). First and second air distribution layers (14, 15) are located between the shells, and between the covering and the foam body. - The foam body (2) has a porous covering (3) in the resting- or contact area (4). A first flexible shell (7) opposite this area includes cavities (8) across the foam body. A second flexible shell (9) is sealed below the first, and includes a housing (10) sealing with the fan (11). First and second air distribution layers (14, 15) are located between the shells, and between the covering and the foam body. The distribution layers are textile with a network of pores connecting longitudinally and transversely. A sealed separation layer (16) extends between the foam and the second air distribution layer. It faces the upper openings of the cavities. The covering comprises a facing textile layer (5) and a flexible layer (6) for comfort. The first shell has a returned section (12) inside which the edge (13) of the second shell is sealed. The seat filling so formed, retains its ventilation qualities after 900,000 cycles of testing for wear. - An INDEPENDENT CLAIM is included for the method of making the seat padding structure, using a molding and foaming process.</p> |
