縫着して接ぎ合わせている。2. Description of the Related Art Conventionally, for example, as a trim cover used for a seat cushion (SC) of an automobile seat as shown in FIG. 5, there is a trim cover using leather (cowhide, horsehide, etc.). This trim cover has a frame (A) with a predetermined shape
It is formed by sewing (A), the body (B) and the town (C). Then, as shown in FIG. 6, the frame (A) and the like are made of a slab elastic material (20) made of urethane foam and cut into a predetermined shape in order to improve the feel of the skin. Is integrally sewn with the sewing thread (4) on the back surface of the sheet and joined together.

At the same time as cutting 0), the elastic piece (20) is cut into the skin piece (1
It is done by gluing it to the outer circumference of 0).

る。Therefore, each skin piece (1
Since 0) is leather and has different elasticity and the like, the quality is uneven, while the elastic piece (20) has elasticity. for that reason,
Skilled work is required for sewing the frame (A) and the like, and the workability is poor, and one or both of them float up as shown by the chain line in FIG. 6, resulting in unstable quality. In addition, for example, when the body (B) is sewn to the frame (A), the skin pieces (10) that are the surface sides of the frame (A) and the body (B) are joined and overlapped with each other, but the outer surface is formed. Since the elastic piece is not formed with a notch for positioning, the body (B) is accurately positioned and cannot be joined to the frame (A).

い欠点がある。On the other hand, for a trim cover which does not use leather, as disclosed in Japanese Utility Model Laid-Open No. 3-31399,
It is disclosed that a flexible material is sandwiched between an outer skin piece and an elastic piece, and the outer skin piece and the elastic piece are bonded to each other at an outer peripheral portion of the flexible material. When this skin piece is made of leather, the skin piece has rigidity, and therefore the elasticity of the elastic piece is impaired by the flexible material, and there is a drawback that it cannot be used as a trim cover.
