Abstract
Official abstract text for this publication.
A trim cover for a seat includes: a high extensible skin material; and a low extensible skin material. A joint part of the edge portion of the high extensible skin material and the edge portion of the low extensible skin material has a plurality of highly extensible protrusions and a plurality of low extensible protrusions, the plurality of highly extensible protrusions and the plurality of low extensible protrusions are each formed in a sharp tapered shape and are arranged alternately in an extending direction of the joint part, and at least a part of a boundary line between the highly extensible protrusion and the low extensible protrusion, which are adjacent in the extending direction of the joint part, is deviated from a line segment formed by connecting respective tips of the highly extensible protrusion and the low extensible protrusion to the low extensible protrusion side.
First claim
Opening claim text (preview).
What is claimed is: 1. A trim cover for a seat comprising: a high extensible skin material; and a low extensible skin material, wherein: an edge portion of the high extensible skin material and an edge portion of the low extensible skin material are bonded to each other; a joint part of the edge portion of the high extensible skin material and the edge portion of the low extensible skin material has a plurality of highly extensible protrusions provided in the edge portion of the high extensible skin material and a plurality of low extensible protrusions provided in the edge portion of the low extensible skin material; the plurality of highly extensible protrusions and the plurality of low extensible protrusions are each formed in a sharp tapered shape and are arranged alternately in an extending direction of the joint part; and at least a part of a boundary line between the highly extensible protrusion and the low extensible protrusion, which are adjacent in the extending direction of the joint part, is deviated from a line segment formed by connecting respective tips of the highly extensible protrusion and the low extensible protrusion to the low extensible protrusion side. 2. The trim cover according to claim 1 , wherein the boundary line has a circular arc shape. 3. The trim cover according to claim 1 , wherein an intersection angle between the line segment formed by connecting respective tips of the highly extensible protrusion and the low extensible protrusion which are adjacent in the extending direction of the joint part and the extending direction of the joint part is 22.5° or more. 4. The trim cover according to claim 1 , wherein a difference between an elongation rate of the high extensible skin material and an elongation rate of the low extensible skin material is 20% or more. 5. The trim cover according to claim 1 , wherein each protruding length of the highly extensible protrusion and the low extensible protrusion is 50 mm or more. 6. A vehicle seat comprising: the trim cover according to claim 1 ; and a cushion pad covered with the trim cover.
