The present invention relates to an air-conditioning system part (1) made of woven or non-woven cloth comprising a wall provided with at least first system of through-holes (21) for air distribution, whereby the through-holes of the first system are characterized in that the double of the root of the quotient of the through-hole (21) surface value in the inlet thereof and the value {pi} is less than or equal to the value of thickness of the part (1) wall in a region adjacent to the through-hole (21) and that the through-hole (21) axis (O1) forms with the plane of the through-hole (21) inlet an angle {alpha} = 60 degrees to 89 degrees, preferably 80 degrees to 88 degrees, most preferably 83 degrees to 87 degrees. |
