Description

The present invention relates to a vehicle in which a seat cover that constitutes the appearance of a seat includes a first skin piece, a second skin piece, and a line fastener that engages the edges of the first skin piece and the second skin piece. for sheet.

This type of seat cover is typically composed of a plurality of skin pieces, and the edges of adjacent skin pieces are sewn together or detachably attached with wire fasteners. For example, in a seat back that serves as a backrest, a bag-like seat cover has a skin piece on the side of the saddle that serves as the side of the seat and a skin piece on the back surface side, and covers internal members such as a seat frame and a seat pad. are doing. In some cases, the edges of these skin pieces are detachably attached to each other by a line fastener that extends vertically in consideration of the convenience of arranging the seat cover. That is, when the seat cover is installed, the wire fastener is opened to widen the space between the two skin pieces, so that the seat cover can be smoothly fitted over the inner member of the seat back. Then, in order to make the seat cover bag-like again after the covering work, the wire fastener is closed to the lower end portion and the edges of the two upholstery pieces are hooked.

Here, it can be said that it is better not to expose the end portion of the hooked wire fastener to the outside as it is, from the viewpoint of ensuring the appearance of the sheet. For example, an automobile seat back disclosed in Patent Document 1 has a seat skin corresponding to the seat cover of the present invention and a slide fastener corresponding to the wire fastener of the present invention. The seat upholstery has a pair of adjacent upholstery pieces, and a slide fastener is arranged between the pair of upholstery pieces. This slide fastener has a cloth tape sewn to the edge of one skin piece, another cloth tape sewn to the edge of the other skin piece, and a slider for hooking both cloth tapes. In the known technique, each cloth tape is sewn to the corresponding upholstery piece up to near the end, thereby ensuring the positioning of the slide fastener with respect to the seat upholstery. Further, a tubular storage portion made of cloth is attached to the end of the cloth tape, and the end portion of the slide fastener after hooking is stored in this storage portion. That is, after the slider is slid to the end portion to close the slide fastener, the end portion of the slide fastener after hooking is stored in the storage portion so as not to be exposed to the outside, thereby avoiding deterioration of the appearance of the seat to some extent. can be done.

Patent No. 5477641 specification

By the way, in the known technology, the storage portion itself is exposed to the outside, and the position of the end portion of the slide fastener (wire fastener) after hooking can be seen. Met. Of course, it is also possible to fold the hooked wire fastener and insert the end portion thereof into, for example, the back side of the skin piece on the Kamachi surface side for storage. However, in such a configuration, the insertion of the end portion may cause the skin piece to be deformed and the position to be shifted, and such a situation is not preferable from the viewpoint of maintaining the appearance of the seat cover. For example, the skin piece on the back surface side follows the end part and deforms so that it dents, causing wrinkles in the seat cover and gaps (triangular gaps, etc.) at the joints with the skin piece on the Kamachi surface side. I have something to do. If there is a gap between the two skin pieces, the internal structure of the seat may be exposed through this gap, and when the seat is viewed from the seating surface side, unintended light leakage may occur through the gap. is also of concern. The present invention has been devised in view of the above-mentioned points, and the problem to be solved by the present invention is to secure the positionability of the wire fastener and attach the end portion of the wire fastener after hooking to the seat cover. It is to be stored in a more attractive appearance on the back side.

As a means for solving the above problems, a vehicle seat of the first invention includes a seat cover that constitutes the appearance of the seat, and includes a first skin piece and a second skin piece that is arranged adjacent to the first skin piece. and a line fastener for engaging edges of the first skin piece and the second skin piece. Then, the edges of the first skin piece and the second skin piece are in a hooked state by closing the wire fastener to the end, and the end of the wire fastener after hooking is connected to the first skin piece and the second skin piece. It can be stored by inserting it into the back side of one of the skin pieces. In this type of configuration, it is desirable to store the end portion of the hooked wire fastener in an attractive manner on the back side of the seat cover while ensuring the positioning of the wire fastener.

Therefore, in the vehicle seat of the present invention, the backing material that is spread out in a planar shape is arranged on the back surface of the first skin piece, and the first skin piece and a part of the backing material are fixed to the cover side. and a fastener-side fixing portion that fixes only the end portion of the wire fastener and the backing material. The rest part, except for a part, can move relative to the first skin piece to follow the end part of the hooked wire fastener. Only the reliance material is fixed to the end portion of the wire fastener of the present invention by the fastener-side fixing portion, and the first skin piece is not fixed. For this reason, when storing the end portion of the wire fastener after hooking, the first skin piece can be maintained at a predetermined position without following the insertion of the end portion as much as possible, which is an excellent seat cover. It has a configuration that contributes to ensuring a good appearance. In the present invention, a part of the backing material is fixed to the back side of the first skin piece by the cover-side fixing part, and the end part of the wire fastener is fixed to this backing material by the fastener-side fixing part. there is Therefore, even when the wire fastener is not fixed to the first skin piece before hooking, it can be positioned and arranged at an appropriate position on the first skin piece via the reliance material.

The vehicle seat of the second invention is the vehicle seat of the first invention, wherein the backing material is developed in the surface direction along the back surface of the first skin piece, and the first skin piece and the first skin piece It is in a state of being sandwiched between the inner members in the covered sheet.

A fastening hole for fastening to is provided. The end portion of the wire fastener is arranged on the vehicle floor surface side, and the cover-side fixing portion is provided at a position farther from the vehicle floor surface than the fastening hole. In the present invention, the end portion of the hooked wire fastener can be stored while being inserted into the back side of the corresponding skin piece using the fastening hole as a mark. At this time, by providing the cover-side fixing portion at a position farther from the floor surface of the vehicle than the fastening hole, the first skin piece portion fixed to the wire fastener at this cover-side fixing portion can be inserted into the end portion. It is possible to more reliably avoid situations such as follow-up.

A vehicle seat according to a fourth invention is the vehicle seat according to any one of the first to third inventions, wherein the cover-side fixing portion and the fastener-side fixing portion are provided adjacent to each other in the direction in which the line fastener extends. At the same time, the reliance material is fixed to the wire fastener portion adjacent to the end portion and to the first skin piece portion arranged over the wire fastener portion by the cover-side fixing portion. In the present invention, the fastener-side fixing portion and the cover-side fixing portion are arranged side by side in the direction in which the wire fastener extends, and the cover-side fixing portion fixes the backing material to both the wire fastener and the first skin piece. By doing so, it becomes possible to position and arrange the wire fastener more reliably via the backing material.

A vehicle seat according to a fifth aspect of the invention is the vehicle seat according to any one of the first to fourth aspects of the invention, wherein the backing member has a length dimension of the edge disposed on the distal end side that is greater than that of the opposite edge. It's getting bigger. In the present invention, it is possible to appropriately spread the reliance material into a planar shape by using the relatively large edge on the distal end side as a handle.

A vehicle seat according to a sixth aspect of the invention is the vehicle seat according to any one of the first to fifth aspects of the invention, wherein the backing material is made of a face material thinner than the first skin piece. In the present invention, since the backing material arranged on the back side of the first skin piece is relatively thin, it is possible to avoid as much as possible the generation of unnatural irregularities in the first skin piece caused by the backing material.

A vehicle seat according to a seventh invention is the vehicle seat according to the first to sixth inventions, in which the first skin piece and the second skin piece have different appearances, and the backing material is the second skin. It has a similar appearance to the first skin piece rather than the piece. In the present invention, since the first skin piece and the backing material have similar appearances, it is possible to cover the internal members in the seat with a better appearance by these two members.

According to the first aspect of the present invention, the end portion of the hooked wire fastener can be stored on the back side of the seat cover with good appearance while ensuring the positioning of the wire fastener. Further, according to the second invention, the end portion of the wire fastener can be positioned more stably.

[Seat back forming work]
Here, the right seat back 6 and the left seat back 7 shown in FIGS. 1 to 3 have substantially the same basic configuration, and the forming work is also substantially the same. Therefore, the details of the forming operation will be described below by taking the right seat back 6 as an example. In the right seat back 6, referring to FIGS. 3 and 11, the right and left lower ends of the seat frame 6F are fastened and fixed to brackets BR which form a substantially inverted L shape when viewed from the rear, and stand up from the vehicle floor surface FS. (In FIG. 11, only a portion of the seat frame and the left fastening hole are shown for convenience). Therefore, in a state in which the back side of the seat pad 6P is supported by the seat frame 6F, the bag-like seat cover 6S is put over them. At this time, in the seat cover 6S shown in FIG. 12, the slider 13 is moved upward to open the wire fastener 10 (see the slider shown by the dashed line in FIG. 13). By widening the space between the first skin piece SP1 and the second skin piece SP2 in this way, the seat cover 6S can be smoothly covered over the seat pad 6P and the seat frame 6F. After covering the seat cover 6S, the slider 13 is moved downward to close the wire fastener 10 to the end 10E, and the edges of the first skin piece SP1 and the second skin piece SP2 are hooked. (see slider shown in Figure 13 in practice). The end portion 10E of the hooked wire fastener 10 is formed by the first fastener piece 11 portion and the second fastener piece 12 portion located below the folded portion 6SS of the first skin piece SP1.

12 are hooked to make the seat cover 6S bag-like, the seat pad 6P and the seat frame 6F are covered as shown in FIGS. 13 to 15. Become. By the way, in this embodiment, referring to the circled part in FIG. It is The seat cover portion where the cover-side fixing portion 31 is formed is thicker than the portion above it (the circled portion of FIG. 13 consisting of only the first skin piece SP1 and the first fastener piece 11). It can be said that it is a place where unintended irregularities are more likely to occur. Therefore, in this embodiment, as shown in FIG. 7, the thickness of the backing material 20 arranged on the back side of the first skin piece SP1 is intentionally made small. Therefore, in the seat cover portion where the cover-side fixing portion 31 shown in FIG. 14 is formed, it is possible to avoid the generation of unnatural irregularities caused by the backing material 20 as much as possible, thereby ensuring an excellent appearance of the seat cover 6S. It is a configuration that contributes to

Before or after the above-described hooking operation, the lower end of the seat cover 6S shown in FIG. 4 can be locked to the seat cover 6S via each J-hook. At the time of this locking operation, the backing material 20 is spread in the planar direction (vertical and lateral directions) along the back side of the first skin piece SP1. At this time, in the present embodiment, the relatively large lower edge portion 20d of the backing material 20 is arranged downward, so that the lower edge portion 20d is used as a handle to appropriately spread the backing material 20 into a planar shape. It is possible to Furthermore, by sandwiching the backing material 20 in the unfolded state between the first skin piece SP1 and the seat frame 6F as shown in FIG. It can be positioned and placed.

[Storage of the terminal part of the wire fastener after hooking]
In this embodiment, referring to FIGS. 4 and 12, the hooked wire fastener 10 is folded halfway and its end portion 10E is inserted into the back side of the second skin piece SP2 for storage. In this type of configuration, it is desirable to store the end portion 10E of the hooked wire fastener 10 on the back side of the seat cover 6S in a more attractive manner. That is, it is not preferable from the viewpoint of maintaining the appearance of the seat cover 6S that the first skin piece SP1 is deformed to follow the end portion 10E and be recessed toward the front right side due to the insertion of the end portion 10E. For example, referring to FIGS. 15 and 16, it is assumed that the position P1 of the lower left edge (turned-back portion 6SS) is shifted forward and right due to the depression of the first skin piece SP1. In such a case, a gap (such as a triangular gap) is generated between the first skin piece SP1 and the second skin piece SP2, and the seat frame 6F and the like may be exposed through this gap. Also, referring to FIG. 2, when the seat backs 6 and 7 are viewed from the seating surface side, a gap (such as a triangular gap) between the skin pieces causes a gap between the seat backs 6 and 7. There is also concern that unintended light leakage may occur from the gap C.

Therefore, in the present embodiment, referring to FIG. 4, the backing material 20 is arranged on the back surface of the first skin piece SP1, and the first skin piece SP1 and a part of the backing material 20 are arranged. and a fastener-side fixing portion 32 for fixing only the end portion 10E of the wire fastener 10 and the backing material 20 are provided. The portion of the backing material 20 except for a portion (upper portion of the left edge portion 20a) can move relative to the first skin piece SP1 to follow the end portion 10E of the wire fastener 10 after hooking. That is, only the backing material 20 is fixed to the end portion 10E of the wire fastener 10 by the fastener-side fixing portion 32, and the first skin piece SP1 is not fixed. When storing the end portion 10E of the hooked wire fastener 10, the first skin piece SP1 is kept at the predetermined position P1 without following the insertion of the end portion 10E as much as possible. Therefore, the action of the above-described backing member 20 and the fixing portions 31 and 32 will be described in detail below using the right seat back 6 as an example.

Referring to FIG. 12, when the wire fastener 10 is closed to the end portion 10E, the end portion 10E of the wire fastener 10 after being hooked is arranged to cross the fastening hole 6FH of the seat frame in the vertical direction. there is 4 and 12, the hooked wire fastener 10 is folded back forward, and the end portion 10E is positioned on the back side of the second skin piece SP2 using the fastening hole 6FH as a mark (the height position is used as a reference). can be inserted into At this time, only the backing material 20 is fixed to the end portion 10E of the wire fastener 10 by the fastener-side fixing portion 32, and the lower left edge (folding portion 6SS) of the first skin piece SP1 is not fixed. ing. Therefore, when storing the end portion 10E, the lower left edge (folded portion 6SS) of the first skin piece SP1 should be kept at the predetermined position P1 without following the insertion of the end portion 10E as much as possible. can. By maintaining the first skin piece SP1 at the predetermined position P1, wrinkles in the seat cover 6S and gaps (triangular gaps) between the seat cover 6S and the second skin piece SP2 are avoided as much as possible. It becomes possible to Further, in this embodiment, referring to FIGS. 4 and 11, the cover-side fixing portion 31 is provided at a position farther from the vehicle floor surface FS than the fastening hole 6FH. By doing so, the first skin piece SP1 portion fixed to the wire fastener 10 by the cover-side fixing portion 31 can be prevented from being excessively stretched by the end portion 10E, and the seat cover 6S is prevented from being unintentionally wrinkled. You can avoid it as much as possible.

As shown in FIG. 4, by inserting and storing the end portion 10E of the hooked wire fastener 10 into the back side of the second skin piece SP2, the end portion 10E can be prevented from being exposed to the outside as much as possible. Furthermore, in this embodiment, the backing material 20 is fixed to the end portion 10E of the wire fastener 10 via the fastener-side fixing portion 32 . Therefore, the backing material 20 is arranged to cover the seat frame 6F from the left side by moving forward following the insertion of the end portion 10E while relatively moving so as to be pulled out from the back side of the first skin piece SP1. be done. By arranging the backing material 20 so as to cover the left side of the seat frame 6F in this manner, the exposure of the seat frame 6F to the outside can be more reliably avoided. In this embodiment, since the first skin piece SP1 and the backing material 20 have similar appearances, it is possible to cover the seat frame 6F with a better appearance with these two members.

As described above, only the backing material 20 is fixed to the end portion 10E of the wire fastener 10 of this embodiment by the fastener-side fixing portion 32, and the first skin piece SP1 is not fixed. Therefore, when storing the end portion 10E of the hooked wire fastener 10, the first skin piece SP1 can be maintained at a predetermined position without following the insertion of the end portion 10E as much as possible. The configuration contributes to securing the excellent appearance of the seat cover 6S. In this embodiment, the wire fastener 10 is attached to the backing material 20 by the fastener-side fixing portion 32 while a part of the backing member 20 is fixed to the back side of the first skin piece SP1 by the cover-side fixing portion 31. is fixed at its terminal end 10E. Therefore, even in a state where the wire fastener 10 before hooking is not fixed to the first skin piece SP1, it is possible to position and arrange it at an appropriate position on the first skin piece SP1 via the reliance material 20. can. Therefore, according to this embodiment, the end portion 10E of the hooked wire fastener 10 can be stowed on the back side of the seat cover 6S with good appearance while ensuring the positioning of the wire fastener 10. FIG. Similarly, in the left seat back 7 as well, the end portion of another wire fastener 100 after hooking can be stowed in an attractive manner on the back side of another seat cover 7S.

In addition, in this embodiment, the wire fastener 10 is more stably positioned via the backing material 20 by sandwiching the backing material 20 in the unfolded state between the first skin piece SP1 and the seat frame 6F (internal member). can be placed Further, in this embodiment, the end portion 10E of the hooked wire fastener 10 can be stored while being inserted into the back side of the corresponding skin piece using the fastening hole 6FH as a mark. At this time, by providing the cover-side fixing portion 31 at a position farther from the floor surface of the vehicle than the fastening hole 6FH, the first skin piece SP1 portion fixed to the wire fastener 10 by the cover-side fixing portion 31 is located at the terminal end. It is possible to more reliably avoid the situation of following the insertion of the portion 10E. Further, in this embodiment, the fastener-side fixing portion 32 and the cover-side fixing portion 31 are arranged side by side in the direction in which the wire fastener 10 extends, and the cover-side fixing portion 31 connects the wire fastener 10 and the first skin piece SP1 to the backing material 20 . are fixed on both sides of the By doing so, the wire fastener 10 can be positioned and arranged more reliably with the contact material 20 interposed therebetween. Further, in the present embodiment, the edge (lower edge 20d) on the side of the end portion 10E, which is relatively large, can be used as a handle to appropriately expand the backing material 20 into a planar shape. Further, in this embodiment, since the backing material 20 arranged on the back side of the first skin piece SP1 is relatively thin, the backing material 20 causes unnatural irregularities (highlights) in the first skin piece SP1. can be avoided as much as possible. In this embodiment, since the first skin piece SP1 and the backing material 20 have similar appearances, these two members cover the seat frame 6F and the seat pad 6P (another example of the internal member) with good appearance. It becomes possible to keep Similarly, in the left seat back 7 as well, the constituent members (SP11, 12, 100, 200, etc.) of the left seat back 7 have the same effects as those of the right seat back 6. FIG.

The vehicle seat 2 of this embodiment is not limited to the embodiment described above, and can take various other embodiments. Although the configuration of the seat cover 6S (shape, size, arrangement position, constituent members, etc.) has been illustrated in the present embodiment, the configuration of each member is not intended to be limited. For example, the first skin piece can be arranged on any of the seating surface, the Kamachi surface, the back surface, etc. of the seat, and the second skin piece can also be arranged at an appropriate position corresponding to the first skin piece. can be kept Also, the seat cover can have a plurality of or a single line fastener, and for example, the left and right edges of the first skin piece shown in FIG. Further, the line fastener can be arranged in an appropriate direction, such as the vertical direction or the seat width direction, according to the structure of the skin piece to be hung. Further, the seat cover can be provided with a notch portion instead of the folded portion, and it is also possible to push aside the left edge of the first skin piece and sew the backing material and the first fastener piece together during sewing. .

Further, in the present embodiment, an example has been described in which the end portion of the hooked wire fastener is stored in the back side of the second skin piece. On the contrary, it is also possible to store the terminal end of the wire fastener after hooking on the back side of the first skin piece. It is possible to keep the edges of the pieces in place. The stowed height position of the end portion of the wire fastener may be based on the fastening hole, or may be set independently of the fastening hole.

Moreover, in this embodiment, although the structure of a backing material and each fixing|fixed part was illustrated, it is not the meaning which limits the structure of a backing material and each fixing|fixed part. For example, as the shape of the backing material, geometric shapes such as various polygonal shapes and semi-circular shapes can be used, but it is desirable that the edges of the backing material on the distal side are relatively wide. The backing material can also be arranged on the back side of the first skin piece by utilizing the frictional force generated between it and the first skin piece. In addition, in the method of arranging the backing material using the frictional force, the backing material may be inserted between the first skin piece and the inner member, or may be left in a non-inserted state. Also, the thickness and appearance of the backing material can be set independently of the first skin piece. In addition, each fixing part can be formed by an adhesive or a joining member (such as a fastener) in addition to the suture line, and both fixing parts can be formed by different suture lines or the like. Further, the cover-side fixing portion can fix the first skin piece and the backing material at a position different from that of the fastener-side fixing portion. For example, the cover-side fixing part can be provided at an appropriate position on the backing material, and as long as part of the backing material can follow the wire fastener, it is provided at an appropriate position such as the upper edge side or the right edge side. be able to.

Further, in this embodiment, the seat back is explained as an example, but the structure of this embodiment can also be applied to other seat constituent members such as a seat cushion. Also, the configuration of the vehicle seat can be changed as appropriate. For example, the shape, size, and number of seat cushions and seat backs can be changed as appropriate according to the number of passengers expected to be seated. The seat back may be fixed to the floor surface of the vehicle via a bracket, or may be connected to the rear portion of the seat cushion via a recliner or the like. The configuration of the present embodiment can be applied to general vehicle seats such as vehicles, aircraft, trains, and ships.
