PROBLEM TO BE SOLVED: To provide an air distribution duct for seat pads, seat pad including the air distribution duct, and manufacturing method therefor contributing to improvement in quality stability and yield by reducing workload and preventing floating of a duct tip end in setting the air distribution duct in a foaming mold.SOLUTION: A synthetic-resin air distribution duct 2 for seat pads includes a duct 21 extending from a base part 26 that includes an air introduction inlet 26e in a back side 2b, and air exhaust outlets 25a provided on he duct 21 in a surface 2a side. The air distribution duct includes through-holes 21c at a back-side pipe wall 21f of the duct 21 facing the air exhaust holes 25a.
【課題】発泡型への配風ダクトのセットで、作業負担を少なくして導管先端部の浮き上がり防止を図り、品質安定,歩留まり向上に貢献できるシートパッド用配風ダクト、配風ダクト入りシートパッド及びその製造方法を提供する。【解決手段】裏面2b側にエア導入口26eが在る基部26から導管21が延在して、表面2a側の該導管21にエア噴出口25aが設けられる合成樹脂製のシートパッド用配風ダクト2であって、前記エア噴出口25aに対向する前記導管21の裏面側管壁21fに透孔21cが設けられてなる。【選択図】図1
