Disclosure of Invention
Problems to be solved by the invention
In some cases, the multiple lines of the press lines of the two skin materials are not continuous at the seams of the two skin materials due to the mutual positional deviation of the two skin materials and the positional deviation of the seams when the two skin materials are joined. In particular, when the bead extends obliquely to the joining direction of the two skin materials, discontinuity of the bead at the joint of the two skin materials is likely to occur. When the discontinuity of the press line is generated at the seam of the two skin materials, the design of the seat may be impaired.
The present invention has been made in view of the above circumstances, and an object thereof is to suppress discontinuity of a pattern at a seam between two skin materials to be joined, and to improve design properties of a trim cover and a vehicle seat.
Means for solving the problems
A decorative cover according to an aspect of the present invention is a decorative cover formed by joining a plurality of skin materials, and includes two skin materials each having a pattern repeated in a joining direction, and elements constituting the pattern of each of the two skin materials are arranged in parallel in a same pattern in an extending direction of a pocket side at least at the pocket side of each of the two skin materials and extend parallel to the joining direction.
A vehicle seat according to an aspect of the present invention includes the trim cover and a cushion pad covered by the trim cover.
Effects of the invention
According to the present invention, it is possible to suppress the discontinuity of the pattern at the seam of the two skin materials to be joined, and to improve the design of the trim cover and the vehicle seat.

Detailed Description
Fig. 1 shows an example of a vehicle seat for explaining an embodiment of the present invention.
The vehicle seat 1 shown in fig. 1 includes: a seat cushion 2 constituting a seat surface portion, a seat back 3 constituting a backrest portion, and a headrest 4 supporting the head of an occupant seated in the seat. The seat cushion 2, the seat back 3, and the headrest 4 each have a cushion pad made of a foam material such as urethane foam, and a frame for supporting the cushion pad.
The cushion pad of the seat cushion 2 and the cushion pad of the seat back 3 are integrally covered with a trim cover 5, and the cushion pad of the headrest 4 is also covered with a trim cover different from the trim cover 5.
Note that, the cushion pad of the seat cushion 2 and the cushion pad of the seat back 3 may be covered by a single trim cover, or the cushion pad of the headrest 4 may be covered by a single trim cover integrally with the cushion pad of the seat back 3, or the cushion pad of the seat cushion 2 and the cushion pad of the seat back 3, in a case where the headrest 4 is a fixed type headrest and is integrally formed with the seat back 3, or the like.
The decorative cover 5 is formed by joining a plurality of skin materials, and for example, leather (natural leather, synthetic leather) or cloth (woven fabric, knitted fabric, nonwoven fabric) can be used as the skin material. The skin material may have a single-layer structure of leather or cloth, or may have a multilayer structure in which a lining material (e.g., a resin foam such as an elastically deformable flexible urethane foam) is laminated on the leather or cloth as a facing material. The decorative cover 5 may be formed of one kind of skin material, or may be formed of a plurality of kinds of skin materials depending on the location.
Of the plurality of skin materials forming the trim cover 5, the two skin materials 10 and 11 to be joined are skin materials covering the widthwise central portion of the front surface of the seat back 3, and patterns that repeat in the joining direction of the skin materials 10 and 11 (the arrangement direction of the skin materials 10 and 11) are formed on the skin materials 10 and 11, respectively.
Fig. 2 and 3 show the respective patterns of the skin materials 10 and 11.
. In the illustrated example, a plurality of lines of pressing lines 12 are formed on the skin materials 10, 11, respectively, and the plurality of lines of pressing lines 12 include: a group of pressing lines inclined toward one side with respect to the bonding direction and extending in parallel with each other; and a group of pressing lines inclined toward the other side with respect to the bonding direction to be linear and extending in parallel to each other. The two groups of wires intersect in a mesh pattern, and thus form a mesh pattern that repeats in the joining direction of the skin materials 10 and 11. The patterns of the skin materials 10 and 11 and the pattern of the pressing line 12 constituting the patterns are not limited to the illustrated examples.
The lines of press-lines 12 reach the respective pocket sides 10a, 11a of the skin materials 10, 11 to be joined, and the ends 12a of the lines of press-lines 12 formed on the pocket sides 10a, 11a are juxtaposed in the same pattern in the extending direction of the pocket sides 10a, 11 a. The skin materials 10, 11 are joined in such a manner that the end portions 12a of the lines of pressing lines 12 are aligned and the lines of pressing 12 are continuous across the seams 13 of the skin materials 10, 11.
As shown in fig. 3, the multi-line pressing line 12 extends obliquely with respect to the joining direction of the skin materials 10 and 11 except for the end portion 12a, and the end portion 12a linearly extends parallel to the joining direction of the skin materials 10 and 11.
Fig. 4 and 5 show the case where the skin materials 10 and 11 are mutually offset in position in the joining direction and joined.
Fig. 4 shows a case where the end portions 12a of the lines of pressing lines 12 of the respective skin materials 10, 11 extend linearly in parallel with the joining direction of the skin materials 10, 11, and although a part of the end portions 12a appears at the seams 13 of the skin materials 10, 11, the continuity of the pressing lines 12 is maintained across the seams 13.
On the other hand, fig. 5 shows a case where a plurality of lines of the pressing lines 12 of the skin materials 10 and 11 extend obliquely to the ends with respect to the joining direction of the skin materials 10 and 11, and the pressing lines 12 are not uniform at the seams 13 of the skin materials 10 and 11 due to mutual positional deviation of the joining direction of the skin materials 10 and 11, and the pressing lines 12 become discontinuous with the seams 13 as the boundary lines 12.
Although the skin materials 10 and 11 are considered to be bonded while being displaced from each other in the bonding direction, the mutual displacement in the bonding direction of the skin materials 10 and 11 is equivalent to the displacement in the bonding direction of the seams joining the skin materials 10 and 11 on the skin materials 10 and 11, and therefore, when the seams joining the skin materials 10 and 11 are displaced, if the end 12a of the pressure line 12 linearly extends parallel to the bonding direction of the skin materials 10 and 11, the continuity of the pressure line 12 can be maintained.
As described above, the end portions 12a of the plurality of lines of the pressing lines 12 formed on the pocket edges 10a, 11a of the skin materials 10, 11 are arranged in the same pattern in the extending direction of the pocket edges 10a, 11a and linearly extend in parallel with the joining direction of the skin materials 10, 11, whereby continuity of the pressing lines 12 can be maintained even if there is a positional deviation between the skin materials 10, 11 and a positional deviation of the seams, and the design of the garnish cover 5 and the vehicle seat 1 can be improved.
Although the respective patterns of the skin materials 10 and 11 have been described as being formed of a plurality of press lines, the elements forming the patterns may be embosses 14 shown in fig. 6 or embossings 15 shown in fig. 7. In any case, the elements constituting the pattern (embosses 14 or embosses 15) are arranged in the same pattern in the extending direction of the pocket edges 10a, 11a at least at the pocket edges 10a, 11a, and extend parallel to the joining direction of the skin materials 10, 11, and when the skin materials 10, 11 are joined, the continuity of the elements is maintained across the joint of the skin materials 10, 11.
