Abstract

A manufacturing method of a trim cover surface material, includes: providing a jig including a first frame configured to hold an outer periphery of an outer material and a second frame configured to hold an outer periphery of a wadding material by overlapping the wadding material on the outer material which is held by the first frame; holding the outer periphery of the outer material with the first frame of the jig; forming through holes at the outer material which is held by the jig; holding the outer periphery of the wadding material with the second frame of the jig while the outer material is held by the first frame of the jig; and forming stitches at the outer material and the wadding material which are overlapped and held by the jig.

First claim

What is claimed is:

1. A manufacturing method of a trim cover surface material, the trim cover surface material including: an outer material which is formed with a plurality of through holes by a predetermined pattern; and a wadding material laminated on the outer material, the trim cover surface material being formed with stitches that sew together the outer material and the wadding material at gap portions between through hole patterns, the manufacturing method comprising:
providing a jig including: a first frame configured to hold an outer periphery of the outer material; and a second frame configured to hold an outer periphery of the wadding material by overlapping the wadding material on the outer material which is held by the first frame;
holding the outer periphery of the outer material with the first frame of the jig;
forming the plurality of through holes in the outer material which is held by the jig;
holding the outer periphery of the wadding material with the second frame of the jig while the outer material is held by the first frame of the jig; and
forming the stitches in the outer material and the wadding material that are overlapping and held by the jig.

2. The manufacturing method of the trim cover surface material according to claim 1 , further comprising:
positioning the outer material and the jig holding the outer material relative to a drilling machine that forms the plurality of through holes in the outer material; and
positioning the outer material, the wadding material and the jig holding the outer material and the wadding material relative to a sewing machine that forms the stitches in the outer material and the wadding material.

3. The manufacturing method of the trim cover surface material according to claim 2 , further comprising:
coupling the jig to the drilling machine when the jig is holding the outer periphery of the outer material;
decoupling the jig from the drilling machine when the jig is holding the outer periphery of the outer material after forming the plurality of through holes in the outer material; and
coupling the jig to the sewing machine when the jig is holding the outer periphery of the outer material and the outer periphery of the wadding material.

4. The manufacturing method of the trim cover surface material according to claim 1 , wherein holding the outer periphery of the outer material with the first frame of the jig further comprises holding the outer periphery of the outer material with a plurality of clamps of the first frame.

5. The manufacturing method of the trim cover surface material according to claim 1 , wherein holding the outer periphery of the wadding material with the second frame of the jig further comprises holding the outer periphery of the wadding material with a plurality of clamps of the second frame.

6. A manufacturing method of a trim cover surface material, comprising:
forming a plurality of through holes in an outer material of a trim cover surface material while holding an outer periphery of the outer material with a jig; and
forming a plurality of stitches in the outer material thereby coupling the outer material to a wadding material of the trim cover surface material while holding an outer periphery of the wadding material with the jig and while holding the outer periphery of the outer material with the jig,
wherein holding the outer periphery of the outer material with the jig further comprises holding the outer periphery of the outer material with a first frame of the jig; and
wherein holding the outer periphery of the wadding material with the jig while holding the outer periphery of the outer material with the jig further comprises holding the outer periphery of the wadding material with a second frame of the jig surrounding the first frame of the jig.

7. The manufacturing method of the trim cover surface material according to claim 6 , wherein forming the plurality of through holes further comprises mounting the jig on a drilling machine.

8. The manufacturing method of the trim cover surface material according to claim 7 , wherein mounting the jig on the drilling machine further comprises coupling an engaging part of the jig to an engaging part of the drilling machine when the jig holds the outer periphery of the outer material.

9. The manufacturing method of the trim cover surface material according to claim 6 , wherein forming the plurality of stitches further comprises mounting the jig on a sewing machine.

10. The manufacturing method of the trim cover surface material according to claim 9 , wherein mounting the jig on the sewing machine further comprises coupling an engaging part of the jig to an engaging part of the sewing machine when the jig holds the outer periphery of the outer material and the outer periphery of the wadding material.

11. The manufacturing method of the trim cover surface material according to claim 6 , wherein forming the plurality of stitches further comprises forming the plurality of stitches between the plurality of through holes in the outer material coupling the outer material to the wadding material.

12. The manufacturing method of the trim cover surface material according to claim 6 , wherein holding the outer periphery of the outer material with the first frame includes holding the outer periphery of the outer material with a first clamp of the first frame; and
wherein holding the outer periphery of the wadding material with the second frame includes holding the outer periphery of the wadding material with a second clamp of the second frame.

13. The manufacturing method of the trim cover surface material according to claim 6 , further comprising:
positioning the outer material and the jig holding the outer material relative to a drilling machine that forms the through holes in the outer material; and
positioning the outer material, the wadding material and the jig holding the outer material and the wadding material relative to a sewing machine that forms the stitches in the outer material and the wadding material.
