Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a trim cover mounting structure that can prevent a pattern recessed portion at a location where the trim cover is curved and assembled to a cushion pad from being bent or bent.

2. Description of the Related Art In general, in a trim cover in which a surface material, a wading material, and a wading cover are attached or joined together by forming a concavo-convex pattern on the surface side, if the pattern concave part is a deep groove, the cushion pad is curved. It is known that the circumferential length changes between the peaks and valleys of the convex portions of the pattern and the concave portions of the pattern at the place to be adhered, and the pattern is bent at the concave portions, which tends to cause floating folds.

Conventionally, in order to eliminate this drawback, a trim cover is known in which a heat-weldable rigid cloth such as polyvinyl chloride is integrally welded to the back surface of the curved part along with a skin material, a wading material, and a wading cover.
(Jitsukai No. 59-30000).

Problems to be Solved by the Invention However, since this trim cover heat-welds the heat-weldable rigid cloth in the linear pattern recesses, the pattern recesses become even more rigid, resulting in a small rounded shape. Curved parts may encourage the occurrence of floating and folding, and the texture will be poor, resulting in a flat pattern over the entire surface.

Means for Solving the Problems The present invention provides a trim cover mounting structure in which a closed or semi-closed foam strip having a certain degree of rigidity is provided at least on the back surface corresponding to the pattern recess at the part where it is curved and assembled to the cushion pad. It is constructed by fitting and fixing a cushion pad into a concave groove provided on the curved surface of the cushion pad at a depth equal to or greater than the thickness of the foam material band.

Function: With the mounting structure of this trim cover, even if the independent or semi-closed foam strip is curved into a relatively small rounded shape, the tension of the closed cells can sufficiently withstand it, and since it has a certain degree of rigidity, it will not cause creases or bends. Because it doesn't get stiff,
With this fitting attachment, the pattern recessed portion can be curved and assembled to the cushion pad without causing any lifting or folding.

Embodiments The following description will be made with reference to the accompanying drawings.

As shown in FIG. 1, this trim cover consists of a skin material 1, a wadding material 2, and a wading cover 3, which are joined together by sewing or heat welding to form a pattern recess 4. A concavo-convex pattern is formed on the surface. On the back side of this trim cover, a band 5 of independent or semi-closed foam material having a certain degree of rigidity is sewn or glued to at least the part corresponding to the pattern recess 4 where it will be curved and assembled to the cushion pad, as will be described later. It is attached in the same direction as the pattern recess 4 by attaching it to the pattern recess 4 to make it integral. This foam band 5
For example, a synthetic resin such as semi-rigid urethane, PE, PP, foamed rubber, or PVC with a closed cell ratio of 50% to 100% can be used.
It is preferable to use one having a relatively large thickness.

If the trim cover is curved at the point where the foam band 5 is attached, as shown in Figure 2, each closed cell will maintain the void without being crushed, and a tension effect will be exerted, forming a fold line on the surface side. No bending or bending will occur.
Furthermore, since the foam material strip 5 is adhered along the pattern recess 4, it acts to attract and hold the pattern recess 4, so that the pattern recess 4 does not come up and bend. Since it is flexible, it also has a good texture.

When this trim cover is assembled to cover the cushion pad 6 shown in FIG. 3, the portion corresponding to the top portion is curved.
is provided. The foam material strip 5 can be fixed inside the groove 7 with an adhesive. At this time, if the depth of the groove 7 is made larger than the thickness of the foam material strip 5, as shown in FIG. By hanging the pattern concave portions 4 into the pattern convex portions, it is also possible to push up the pattern convex portions, and a pattern with excellent unevenness can be formed.

In the above-described embodiment, the foam band 5 was attached along the pattern recess 4, but if necessary, a flat foam band or a concave-convex foam band in the same direction as the groove direction could be attached over the front surface of the bending part. You may also do so.

Effects of the Invention As described above, according to the trim cover mounting structure according to the present invention, even if the cushion pad is curved according to the curved surface of the cushion pad, no lifting or folding occurs in the pattern concavity, resulting in an appearance with excellent shape retention. Be able to form good sheets.

Claims (1)

[Scope of utility model registration request] A closed or semi-closed foam material strip having a certain degree of rigidity is attached to the back surface corresponding to at least the pattern recess at the point where the cushion pad is curved and assembled, and the depth is the same as or greater than the thickness of the foam material strip. A trim cover mounting structure is characterized in that it is fixed by being fitted into a concave groove provided on the curved surface of a cushion pad.
