  • Device for ventilating vehicle chairs
    Patent number: 6003950
    Abstract: A device for ventilating chairs which has an air-permeable covering portion (13, 14) which is applied over the filling (7) of the chair, an insert (15; 59) located between the covering portion and the filling and a suction device (26) which through a system of suction openings in the covering (57, 60) and the insert (40, 56) evacuates the ventilating air.
