Description

Technical Field

[0001] The present invention relates to a seat. Background Art

[0002] In a seat such as a vehicle seat, a recessed portion may be provided in a seat cushion, a seat back, an armrest, etc. The inner bottom surface and the inner side surface of the recessed portion in the seat are defined by a decorative member (for example, Patent Document 1).

[0003] use Fig.13 The structure of the decorative member provided to define the inner bottom surface and the inner side surface of the recessed portion in the seat according to the conventional technology will be described.

[0004] like Fig.13 As shown, in the seat involved in the prior art, a decorative piece composed of three decorative sheets 901 to 903 sewn three-dimensionally is arranged to define the inner bottom surface and inner side surface of the recess. Fig.13 The structure of the decorative member shown can be applied to a seat belt buckle accommodating portion (a recessed portion for accommodating a seat belt buckle) provided in a seat cushion of a rear seat of a vehicle.

[0005] Specifically, the decorative sheet 901 is a member constituting the bottom surface portion, which defines the inner bottom surface of the seat belt buckle storage portion (recess), and the decorative sheets 902 and 903 are members constituting the side surface portion, which define the inner side surface of the recess. The decorative sheet 903 is bent into a U-shape by two folding lines LN91 and LN92, and the edge 903a is sewn to the edge 901a of the decorative sheet 901 (arrow C1), and the edges 903b and 903c are sewn to the edges 901b and 901c of the decorative sheet 901, respectively (arrows C2 and C3). The edge 902b of the decorative sheet 902 is sewn to the edge 903d of the decorative sheet 903 (arrow C4), and the edge 902c is sewn to the edge 903e of the decorative sheet 903 (arrow C5). Furthermore, the edge 902a of the decorative sheet 902 is not sewn to the edge 901d of the decorative sheet 901, thereby forming a seat belt insertion opening for passing the seat belt therethrough.

[0006] Furthermore, a resin plate 912 is provided on the back side (seat cushion block side) of the bottom portion formed by the decorative sheet 901. The resin plate 912 is sewn to the decorative sheet 901 and the decorative sheet 903 through sewing lines LN93 to LN95 (arrow C6). The resin plate 912 is attached to the decorative member in order to maintain the bottom portion of the decorative sheet 901 in a planar shape and to suppress wrinkles generated on the bottom portion.

[0007] However, in the seat according to the above-mentioned prior art, since the decorative part is formed by three-dimensionally sewing the plurality of decorative sheets 901 to 903, it is possible to cause an increase in manufacturing cost and problems in appearance quality. Specifically, in the seat according to the above-mentioned prior art, in order to sew the plurality of decorative sheets 901 to 903, the sewing operation becomes complicated, and a complicated management operation is required for managing the components of the plurality of decorative sheets 901 to 903. Therefore, it is possible to cause an increase in manufacturing cost.

[0008] In addition, in the seat according to the above-mentioned prior art, since the plurality of decorative sheets 901 to 903 are three-dimensionally sewn together to form a three-dimensional decorative piece, there may be a size error of each decorative sheet 901 to 903 during cutting and / or an error during sewing, which may cause problems in appearance quality.

[0009] The above-mentioned vehicle seat is only an example, and the same problem may exist in seats other than vehicle seats.

[0047] In addition, Figure 4Although not shown in the figure, the front right side surface 10e2 is similar to the rear right side surface 10e1, and the portion facing the seat belt insertion opening 2d is folded back and the overlapping portion is sewn.

[0048] 3. Structure of the decorative member 10 before three-dimensional sewing

[0049] use Figure 5 The structure of the decorative member 10 before three-dimensional sewing will be described. Figure 5 It is a development view showing a state in which members constituting the garnish 10 are extracted.

[0050] like Figure 5 As shown, the decorative member 10 is formed in a manner that the parts 10a to 10d, 10e1, and 10e2 each having a rectangular shape are continuous. The side parts 10b to 10d, 10e1, and 10e2 are formed continuously as a whole to have a long strip shape. The bottom part 10a is provided so as to be continuous with the left side part 10b with a line LN1 therebetween, and protrudes in a direction orthogonal to the longitudinal direction of the side parts 10b to 10d, 10e1, and 10e2.

[0051] The decorative member 10 has folded portions 10a2, 10e7, 10e8 and seam allowances 10a1, 10a3, 10b1, 10c1, 10c2, 10d1, 10d2, 10e3 to 10e6 as edges of the respective portions 10a to 10d, 10e1, 10e2. The folded portions 10a2, 10e7, 10e8 and seam allowances 10a1, 10a3, 10b1, 10c1, 10c2, 10d1, 10d2, 10e3 to 10e6 are continuous with the respective portions 10a to 10d, 10e1, 10e2 at lines LN4 to LN8, LN10 to LN12, and LN14 to LN19. The folded portions 10a2, 10e7, 10e are folded back at folding lines LN10, LN14, LN19, and are sewn at respective overlapping portions.

[0052] In the right Figure 5 When the decorative member 10 shown is three-dimensionally sewn, it is bent at the lines LN1 to LN3, LN9, and LN13, and sewn by the butted sewing lines LN5, LN7, LN12, LN16, LN17, and LN18. Specifically, the sewing line LN5 is sewn with the sewing line LN17, and the sewing line LN7 is sewn with the sewing line LN18. In addition, the sewing line LN12 is sewn with the sewing line LN16. Moreover, it is sewn with the edge (seam allowance) of the seat surface decorative member 9 by the sewing lines LN4, LN6, LN8, LN11, and LN15.

[0053] 4. Sewing of the resin plate 12 and the bottom surface 10a of the decorative member 10

[0054] use Fig. 6A and Figure 6B Sewing of the resin plate 12 and the bottom surface portion 10 a of the garnish 10 will be described. Fig. 6A The resin plate 12 included in the rear vehicle seat 1 according to the present embodiment is shown. Figure 6B As a comparative example, the use of Fig.13 The resin plate 912 included in the seat according to the conventional technology will be described.

[0055] like Figure 6B As shown, in the seat involved in the prior art, in order to be with the decorative pieces 901, 903 (refer to Fig.13 ) must be sewn with the resin plate 912 along the three sewing lines LN93 to LN95. That is, in the prior art, in order to sew the three decorative sheets 901 to 903 in three dimensions, the edge 901a of the decorative sheet 901 and the edge 903a of the decorative sheet 903 must be sewn along the sewing line LN95 (refer to FIG. Fig.13 ) and sew the edge 901b of the decorative sheet 901 and the edge 903b of the decorative sheet 903 along the sewing line LN93 (refer to Fig.13 ) and sew the edge 901c of the decorative sheet 901 and the edge 903c of the decorative sheet 903 along the sewing line LN94 (refer to Fig.13 And, because the extension direction of sewing line LN95 is the direction intersecting with sewing lines LN93 and LN94, the action of rotating the decorative pieces 901, 903 and the resin plate 912 must be performed when sewing.

[0056] On the other hand, Fig. 6A As shown, in the vehicle rear seat 1 according to the present embodiment, the garnish 10 and the resin plate 12 can be joined by sewing only along two sewing lines (linear lines) LN20 and LN21 parallel to each other. That is, as described above, since the garnish 10 is formed of a continuous member and is provided so that the bottom surface 10a and the left side surface 10b are continuous, there is no need to sew along the two sewing lines (linear lines) LN20 and LN21. Figure 6B Therefore, in the present embodiment, the joining of the decorative member 10 and the resin plate 12 is completed by sewing along the two sewing lines LN20 and LN21, which are the sewing lines along the sewing of the seams between the bottom surface 10a and the rear side surface 10c and the sewing of the seams between the bottom surface 10a and the front side surface 10d. Therefore, in the present embodiment, the joining of the decorative member 10 and the resin plate 12 can be achieved by repeatedly sewing in the same direction without rotating the decorative member 10 and the resin plate 12 during sewing.

[0057] 5. Effect

[0058] In the vehicle rear seat 1 according to the present embodiment, the decorative member 10 defining the inner bottom surface and the inner side surface of the seat belt buckle accommodating portion 2b is formed by a continuous member, rather than sewing a plurality of decorative pieces as in the prior art. Furthermore, in the decorative member 10, since the bottom surface portion 10a and the side surface portions 10b to 10d, 10e1, and 10e2 are continuous, the work related to sewing can be reduced by the amount corresponding to the continuous portion.

[0059] In addition, in the vehicle rear seat 1 according to the present embodiment, since the three-dimensional decorative member 10 is formed by three-dimensionally sewing a continuous member, the man-hours for managing the members during manufacturing can be reduced compared to the case where the decorative member is formed by three-dimensionally sewing a plurality of decorative sheets 901 to 903 as in the above-mentioned prior art. Thus, the manufacturing cost can be reduced.

[0060] In addition, in the vehicle rear seat 1 according to the present embodiment, since the decorative member 10 is formed by three-dimensionally sewing one member, the dimensional error during the cutting and sewing of the member can be suppressed to a small level compared to the prior art in which a plurality of decorative sheets 901 to 903 are three-dimensionally sewn. Thus, a high appearance quality can be achieved.

[0061] In addition, in the vehicle rear seat 1 involved in the present embodiment, since the decorative part 10 is constructed in a manner that the bottom surface part 10a and the left side surface part 10b are continuous, the side surface parts 10b to 10d, 10e1, and 10e2 can be erected from the bottom surface part 10a with the continuous part (line LN1) as the boundary, and by sewing the sewing line LN5 and the sewing line LN17, sewing the sewing line LN12 and the sewing line LN116, and sewing the sewing line LN7 and the sewing line LN18, the decorative part 10 with a three-dimensional shape can be constructed by a single component, and a higher appearance quality can be achieved while suppressing the increase in manufacturing costs as described above.

[0062] Furthermore, in the vehicle rear seat 1 according to the present embodiment, the rear right face portion 10e1 and the front right face portion 10e2 are sewn together at the seam allowances 10e3 and 10e4 (sewing lines LN12 and LN16) to form the annular side face portions 10b to 10d, 10e1, and 10e2, and the inner side of the seat belt buckle receiving portion 2b can be entirely defined by the decorative member 10. That is, the decorative member 10 having a three-dimensional shape that defines the entire inner bottom surface and inner side surface of the seat belt buckle receiving portion 2b can be formed by three-dimensionally sewing one member.

[0063] In addition, in the vehicle rear seat 1 involved in this embodiment, since the stitching portion (stitching portion S4) between the rear right side surface 10e1 and the front right side surface 10e2 is arranged in the central part of the right side surface 10e in the vehicle width direction (between the corners), the rigidity of the right side surface 10e can be improved, which has an advantage in achieving high appearance quality.

[0064] Furthermore, in the vehicle rear seat 1 involved in the present embodiment, since the right edge of the bottom surface portion 10a and the lower edge of the right side surface portion 10e are not sewn together and the portion is used as the seat belt insertion opening portion 2d for passing the seat belt, even if an opening portion is not separately provided in the side surface portions 10b to 10d or the bottom surface portion 10a, the seat belt insertion opening portion 2d can be provided without sewing and thus improving workability.

[0065] Furthermore, in the vehicle rear seat 1 according to the present embodiment, the end edges of the bottom surface portion 10a and the right side surface portion 10e constituting the edge of the seat belt passage opening portion 2d are folded back (folded back portions 10a2, 10e7, 10e8), and the overlapping portions thereof are sewn, thereby achieving high rigidity at the edge of the seat belt passage opening portion 2d, and reliably suppressing the buckle from being buried or sinking due to an undesired opening.

[0066] Furthermore, in the vehicle rear seat 1 according to the present embodiment, since the bottom portion 10a of the decorative member 10 and the resin plate (reinforcement plate) 12 are sewn along two parallel straight lines (sewn by sewing lines LN20 and LN21), high workability can be ensured without changing the sewing direction when sewing the bottom portion 10a and the resin plate 12. Thus, an increase in manufacturing cost can be suppressed.

[0067] In the vehicle rear seat 1 according to the present embodiment, the bottom surface 10a and the rear side surface 10c are overlapped and sewn when the sewing line LN20 is sewn, and the bottom surface 10a and the front side surface 10d are overlapped and sewn when the sewing line LN21 is sewn (see FIG. Figure 3 ), therefore, strong seaming of the bottom portion 10a and the resin plate 12 can be achieved, and high workability can be ensured.

[0068] As described above, in the vehicle rear seat 1 according to the present embodiment, when the garnish 10 defining the inner bottom surface and the inner side surface of the seat belt buckle accommodating portion (recess) 2 b is provided, an increase in manufacturing cost can be suppressed and an excellent appearance quality can be achieved.

[0069] [Modification 1]

In this modification, the lower edge of the rear right side surface portion 10e1 and the right edge of the bottom surface portion 10a are sewn together (sewing portion S10).

[0072] On the other hand, in the portion located at the front side in the vehicle front-rear direction relative to the stitching portion S4 between the rear right side face portion 10e1 and the front right side face portion 10e2, the lower edge of the front right side face portion 10e2 and the right edge of the bottom face portion 10a are not stitched together, but a seat belt insertion opening portion 22d is provided. That is, in this modification, a seat belt insertion opening portion 22d smaller than that of the above-mentioned embodiment is provided in the vehicle width direction. Moreover, in the stitching portion S4, the rear right side face portion 10e1 and the front right side face portion 10e2 are stitched together, and in the stitching portion S10, the lower edge of the rear right side face portion 10e1 and the right edge of the bottom face portion 10a are stitched together, so there is an advantage in ensuring high rigidity of the right side face portion 10e.

[0073] In addition, in this modification, since the structure other than the form of the seat belt insertion opening 22d is the same as that of the above-mentioned embodiment, the same effect as that of the above-mentioned embodiment can be obtained.

[0131] In the seat involved in the above technical solution, the decorative member defining the inner bottom surface and the inner side surface of the recessed portion is formed by three-dimensionally sewing a continuous member. Therefore, compared with the above-mentioned conventional technology of three-dimensionally sewing a plurality of decorative pieces, the work involved in sewing can be reduced.

[0132] Furthermore, in the seat according to the above technical solution, the decorative part is formed of a continuous member, so compared with the case where the decorative part is composed of multiple members as in the above-mentioned conventional technology, the man-hours for member management during manufacturing can be reduced, thereby reducing the manufacturing cost.

[0133] Furthermore, in the seat involved in the above technical solution, since a three-dimensional decorative part is formed by three-dimensionally sewing a continuous member, the dimensional error during cutting and sewing of the member can be suppressed to a smaller level compared with the case of using multiple members. Thus, a high appearance quality can be achieved.

[0134] In the seat involved in the above technical solution, the side surface portion can have a long strip shape, and the bottom surface portion can be configured as: it is continuous with a portion of the long side extending along the length direction of the side surface portion, and it protrudes from the continuous portion in a direction intersecting with the length direction, and the bottom surface portion and the side surface portion can be sewn to each other at least partially in the edge portion except for the mutually continuous portion.

[0135] In the seat involved in the above technical solution, a portion of the long side extending in the length direction in the side portion is formed as a decorative piece in a manner that the bottom portion and the side portion are continuous. Therefore, the side portion can be erected from the bottom portion with the continuous portion as the boundary, and a three-dimensional decorative piece can be formed from a single component by sewing at least a portion of the edges to each other. As described above, the increase in manufacturing costs can be suppressed and a high appearance quality can be achieved.
