At least one limiting wall (′) of at least one air outlet duct () is provided with a cylinder (′) extending in the direction of flow of the air outlet duct () and in parallel to the reclining surface () at the discharge-side end, wherein the cylinder (′) has a diameter corresponding to 0.005 to 0.2 times the duct width of the air outlet duct (). According to a variant, at least one limiting wall (′) of at least one air outlet duct () is provided with at least one inner wall () forming a nozzle at the discharge-side end. The distance between the limiting wall (′) and the inner wall () forming a nozzle with the limiting wall (′) is 0.01 to 0.5 times the duct width of the air outlet duct ().
