To prevent the foamed resin from leaking out from the seamed portion of the skin sheet during foaming.SOLUTION: In a headrest 10 of the present disclosure, of a headrest body 10H, a seamed portion 22 below a middle position in the vertical direction (for example, a position at a height of 1/4 to 1/5 from the lower end of the headrest body 10H) is a seamed sewing portion 23. A seamed portion 22 above the middle position in the vertical direction is a seamed welding portion 24. At the seamed sewing portion 23, skin sheets 21 are sewn together with a sewing thread 23A, and at the seamed welding portion 24, synthetic leather layers 31 of the skin sheets 21 are joined together.SELECTED DRAWING: Figure 5
【課題】発泡途中で、発泡樹脂が表皮シートの継ぎ合わせ部から漏れ出てしまうことを防ぐことが求められている。【解決手段】本開示のヘッドレスト10では、ヘッドレスト本体10Hのうち、上下方向の途中位置(例えば、ヘッドレスト本体10Hの下端から1/4~1/5の高さの位置)から下側の継ぎ合わせ部22は、継ぎ合わせ縫製部23となっていて、上下方向の途中位置から上側の継ぎ合わせ部22は、継ぎ合わせ溶着部24となっている。継ぎ合わせ縫製部23では、表皮シート21同士が縫糸23Aにより縫い合わされ、継ぎ合わせ溶着部24では、表皮シート21の合皮層31同士が結合している。【選択図】図5
