PROBLEM TO BE SOLVED: To provide a seat cushion containing a duct, which can reduce pain caused by a hog ring while suppressing reduction in air volume of the duct.SOLUTION: In a seat cushion containing a duct, a wire exposure hole 15 for exposing a wire 12 in a pad is formed on a front side surface of a seat pad. Pairs of movement restriction projections 40, which project to the front side of the seat pad and are arranged in pairs so as to sandwich the wire exposure hole 15 in an extension direction of the wire 12 in the pad, are disposed in a duct 30 so as to sandwich the wire 12 in the pad. A distance D4 between the movement restriction projections 40 disposed so as to sandwich the wire 12 in the pad is narrower than an outer diameter D3 of a hog ring 25. A distance D2 between the movement restriction projections 40 disposed so as to sandwich the wire exposure hole 15 is narrower than the outer diameter D3 of the hog ring.SELECTED DRAWING: Figure 6
【課題】ダクトの風量低下を抑えつつ、ホグリングによる痛みを軽減可能なダクト入りシートクッションを提供する。【解決手段】ダクト入りシートクッションでは、シートパッドの表側面に、パッド内ワイヤ12を露出させるワイヤ露出孔15が形成されると共に、ダクト30に、シートパッドの表側に突出すると共に、パッド内ワイヤ12の延在方向でワイヤ露出孔15を挟むように対をなして配置される移動規制突部40が、パッド内ワイヤ12を挟むように1対ずつ配設され、パッド内ワイヤ12を挟むように配置された移動規制突部40同士の間隔D4は、ホグリング25の外径D3より狭く、ワイヤ露出孔15を挟むように配置された移動規制突部40同士の間隔D2は、ホグリングの外径D3より狭くなっている。【選択図】図6
