1. A ventilation system comprising:
- a seat having an upholstery part, the upholstery part including a pad and a shaped body, the shaped body including;
a bearing surface;
a rear side opposite the bearing surface;
a first opening extending generally from the bearing surface to the rear side; and
a second opening;
a first fan coupled to the first opening and configured to generate a first flow of air generally perpendicular to the bearing surface; and
a second fan coupled to the second opening and configured to generate a second flow of air generally transverse to the first flow of airwherein the shaped body includes a first duct for conveying the first flow of air and a second duct for conveying the second flow of air, the first duct having a first end and a second end, the first end being coupled to the first opening and the second end being closed; and
wherein air flows between the second duct and the first duct via the pad.
