To provide a trim cover of a vehicle seat, of which stretch characteristics at a junction between a high stretch skin material and a low stretch skin material are gradually changed, thus reducing discomfort of a seat occupant sufficiently.SOLUTION: A trim cover 7 of a vehicle seat 1 includes a high stretch skin material 10 and a low stretch skin material 11 that are joined together. A junction 12 between an edge of the high stretch skin material 10 and an edge of the low stretch skin material 11 has: multiple high stretch protrusions 13 provided at the edge of the high stretch skin material 10; and multiple low stretch protrusions 14 provided at the edge of the low stretch skin material 11. The multiple high stretch protrusions 13 and the multiple low stretch protrusions 14 each formed in a sharp tapered shape are disposed alternately in a direction of extension of the junction 12. At least a part of a border line BL between the high stretch protrusion 13 and the low stretch protrusion 14 adjacent to each other in the direction of extension of the junction 12 lies on the side of the low stretch protrusion 14, relative to a line segment SL connecting a tip of the high stretch protrusion 13 to a tip of the low stretch protrusion 14.SELECTED DRAWING: Figure 3
【課題】乗物用シートのトリムカバーの高伸張性表皮材と低伸張性表皮材との接合部における伸張特性を緩やかに変化させ、着座者が覚える違和感を十分に軽減する。【解決手段】乗物用シート1のトリムカバー7は、互いに接合される高伸張性表皮材10と、低伸張性表皮材11とを含み、高伸張性表皮材10の縁部と低伸張性表皮材11の縁部との接合部12は、高伸張性表皮材10の縁部に設けられている複数の高伸張性突部13と、低伸張性表皮材11の縁部に設けられている複数の低伸張性突部14と、を有し、複数の高伸張性突部13と、複数の低伸張性突部14とは、先鋭なテーパ状にそれぞれ形成され、接合部12の延在方向に交互に配置されており、接合部12の延在方向に隣り合う高伸張性突部13と低伸張性突部14との間の境界線BLの少なくとも一部は、高伸張性突部13及び低伸張性突部14それぞれの先端を結ぶ線分SLを低伸張性突部14側に越えている。【選択図】図3
