Abstract

In a skin material for a vehicle, a general surface and a predetermined shape having an outer appearance which is equal to a joint portion obtained by actually bonding a plurality of skin materials are formed in a one-piece skin material in accordance with a transcription, and an outer appearance which is equal to a three-dimensional outer appearance obtained by actually bonding a plurality of skin materials is formed three-dimensionally by one skin material.

Claims

1-15. -15. (canceled)

16. A skin material for a vehicle, comprising:

a general surface and a predetermined shape having an outer appearance which is equivalent to a joint portion obtained by an actual bonding of a plurality of skin materials that is constructed as a one-piece skin material in accordance with a transcription, the skin material comprising an outer appearance which is equivalent to a three-dimensional outer appearance obtained by actually bonding a plurality of skin materials in a three-dimensional form by one skin material.

17. The skin material for a vehicle as claimed in claim 16, wherein the skin material comprises a form material arranged in portions other than the joint portion in a back surface of the skin material and forming a seat surface having a concavo-convex shape.

18. The skin material for a vehicle as claimed in claim 16, wherein the joint portion having the outer appearance equal to the outer appearance obtained by actually bonding the plurality of skin materials is constituted by any one of a joint in accordance with a sewing, a joint in accordance with a welding process and an ornamental stitch portion provided in the skin material surface.

19. The skin material for a vehicle as claimed in claim 16, wherein the joint portion is formed in a shape protruding from the general surface.

20. The skin material for a vehicle as claimed in claim 16, wherein the skin material is structured such that all or a part of a joint portion shape of a plurality of skin materials, an undercut shape of the joint portion, a shape of a sewing thread, an undercut shape of the sewing thread, a shape of a seam hole, a concavo-convex shape obtained by overlapping the skin materials in the joint portion, and a shape showing a biting state of the sewing thread into the skin material are transcribed.

21. The skin material for a vehicle as claimed in claim 16, wherein the outer appearances equivalent to the three-dimensional outer appearances are provided on the boundary of the joint portion.

22. The skin material for a vehicle as claimed in claim 17, wherein the back surface material is arranged in the form material and the form material is pinched by the back surface material and the skin material.

23. The skin material for a vehicle as claimed in claim 18, wherein the ornamental stitch portion is constituted by a pattern portion.

24. A seat for a vehicle, comprising a skin material covering, the skin material covering comprising:

a general surface and a predetermined shape having an outer appearance which is equal to a joint portion obtained by an actual bonding of a plurality of skin materials that is constructed as a one-piece skin material in accordance with a transcription, the skin material comprising an outer appearance which is equivalent to a three-dimensional outer appearance obtained by actually bonding a plurality of skin materials in a three-dimensional form by one skin material.

25. A manufacturing apparatus for a seat for a vehicle covered with a skin material, the manufacturing apparatus comprising:

a forming metal mold for forming the skin material, the forming metal mold comprising a porous metal spray layer forming a cavity surface, and a porous backup layer holding the metal spray layer.

26. The manufacturing apparatus of a seat for a vehicle as claimed in claim 25, wherein a thickness of the metal spray layer is equal to or more than 0.7 mm and equal to or less than 1.0 mm.

27. The manufacturing apparatus of a seat for a vehicle as claimed in claim 25, wherein the forming metal mold is constituted by a vacuum mold.

28. The manufacturing apparatus of a seat for a vehicle as claim 25, wherein the backup layer is constituted by a first layer and a second layer, a thickness of the first layer is equal to or more than 7.0 mm and equal to or less than 10.0 mm, and a thickness of the second layer is equal to or more than 50.0 mm and equal to or less than 70.0 mm.

29. The manufacturing apparatus of a seat for a vehicle as claimed in claim 28, wherein the first layer is formed by a metal powder, and a diameter of a hole formed therebetween is equal to or more than 1.5 mm and equal to or less than 2.0 mm.

30. The manufacturing apparatus of a seat for a vehicle as claimed in claim 28, wherein the second layer is formed by a metal powder, and a diameter of a hole formed therebetween is equal to or more than 3.0 mm and equal to or less than 5.0 mm.
