Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to an end treatment structure for a trim cover in a vehicle seat.

<<Prior Art>> As shown in FIG. 9, a conventional vehicle seat has a pad material 2 of a seat 1 attached to a seat frame 3, and a front trim cover part 4 and a rear trim cover part 5 are joined together in advance. It has a structure in which a pad material 2 is wrapped in a trim cover 6 formed in the shape of a bag. Bag-like parts 4A and 5A are formed at the ends of each trim cover part 4 and 5 by sewing or other joining means, and a dedicated jig such as a hook ringer is connected between both the bag-like parts 4A and 5A at this end. They are joined by a plurality of clips 7 that are attached at predetermined intervals using the trim cover 5, and this joint is covered by an extension 5B of the rear trim cover 5, so that the clips 7 are hidden. In some cases, a wire or the like is inserted as a core material into the bag-shaped parts 4A and 5A to be joined by the clip 7, and the clip 7 is fixed to this wire.

<<Problems to be solved by the invention>> However, in the conventional trim cover terminal processing structure for vehicle seats, it is necessary to join multiple clips 7 using a special jig; It's heavy and tiring, and if you don't have the skill, there is a risk of mishitting or getting injured. Therefore, there are problems of poor workability and high costs. Moreover, if the sheets are simply joined using the clip 7, the appearance will be poor if the joined parts are visible because the sheets are hidden. Therefore, in order to hide the clip 7 at this joint part, it is covered with the extension part 5B of the rear trim cover 5, but this extension part 5B
Generally, the extension part 5B is rolled up and arranged, so when the seat is folded forward, the extension part 5B turns over and the clip 7 is visible, and the tip of the extension part 5B becomes wavy, which does not look very good. It was hot.

The present invention has been developed in view of the above problems, and eliminates the multiple clips that were attached using special jigs in the conventional structure, and has a structure that can be easily operated without requiring any skill. To provide a trim cover end processing structure for a vehicle seat, which improves workability and reduces man-hours, and at the same time prevents spoiling the appearance even if the joint part is not covered with a trim cover extension. The purpose is to

<Means for Solving the Problems> In order to achieve the above object, the present invention uses a trim cover formed by joining a front trim cover portion and a rear trim cover portion to each other in a bag shape to cover the seat pad material. The terminal processing structure of a trim cover in a covered vehicle seat includes a bag-shaped portion provided at the terminal end of each trim cover portion, and a substantially V-shaped shape having a pair of wire pieces connected to each other at one end. A wire member is provided, each of the other end portions of the wire piece is inserted from one end side of the different bag-like portions, and the respective other end portions protruding to the other end side are fixedly connected to each other to connect each of the bag-like portions. pressed against each other,
The device is configured to close the connection between the terminals.

<<Operation>> According to the present invention, each other end of a pair of wire pieces in a wire member is inserted from one end side of a different bag-shaped part, and the respective other ends protruding from the other end are fixedly connected to each other. The respective ends of the front trim cover part and the rear trim cover part are joined to each other and closed. Therefore, the work of joining and fixing is only required at one end, which improves work efficiency.
Moreover, since only one boundary line created by the bag-shaped parts abutting each other is visible at the joint, the appearance of the joint is not degraded.

<<Example>> Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an exploded perspective view, partially cut away, showing the schematic structure of a seat bag to which a trim cover end processing structure for a vehicle seat according to an embodiment of the present invention is applied. In the figure, the seat bag 11 is composed of a pad material 12, a seat frame 13 to which the pad material 12 is attached, a trim cover 14 that covers the pad material 12, and the like. The pad material 12 is attached with the seat frame 13 held by the main body portion 12A and the lower bent portion 12B. On the other hand, the trim cover 14 that covers the pad material 12 is made by joining the front trim cover part 15 and the rear trim cover part 16 in advance into a bag shape, and covers the pad material 12 so as to store the pad material 12 in the bag shape. Further, at the ends of the front trim cover part 15 and the rear trim cover part 16, there are bag-shaped parts 15A, respectively.
and 16A are formed by sewing or other joining means. And the trim cover 14 is made of padded material 12
After storing, the bag-like parts 15A, 16A of the terminal are joined to each other by a joining means and closed. This bag-like part 15
The joining means for joining A and 16A is a pair of wire pieces 1 in which a relatively rigid metal wire is folded at the middle part and one end part 20 is connected to each other.
It is composed of a wire member 19 formed into a V-shape by 7 and 18. Also each piece of wire 1
The other end portions 21 and 22 of 7 and 18 are bent approximately circularly in opposite directions within one plane. However, this bent tip does not completely contact the main body of each wire piece 17, 18, and at least each wire piece 17, 1
A gap is formed between the main body and the main body by a diameter separation of 8.

When the ends of the trim cover parts 15 and 16 are joined to each other with the wire member 19, the other end 21 of the wire piece 17 is connected from one end side of the bag-shaped part 15A, and the other end 22 of the wire piece 18 is End 1
6A from one end side, and each bag-shaped part 1
This is done by fixedly connecting the other end portions of 5A and 16A that protrude toward the other end side. This other end 2
For example, as shown in FIG. 2, the fixed connections 1 and 22 penetrate into each bent portion through a gap formed between the bent tip at each other end 21 and 22 and the main body of each wire piece 17 and 18. This is done by being engaged. At the time of this engagement, each bag-shaped portion 15A, 1
6A is strongly sandwiched between the wire pieces 17 and 18 from the inside, and at the same time, a reaction force acts between the other ends 21 and 22, so that the other ends 21 and 22 are firmly engaged with each other.

As explained above, according to this structure, the ends of each trim cover 15, 16 can be connected to the pair of wire pieces 17, without providing a clip member in the middle part of the ends as used in the conventional end processing structure.
18 can be reliably joined. Furthermore, at the joint, only one boundary line created by the bag-shaped parts 15A, 16A coming into contact with each other can be seen. Therefore, unlike the conventional structure, there is no clip member that makes the appearance bad, and there is no need to separately cover this joint with a cover or the like. Furthermore, in the joining work, the pair of wire pieces 17 and 18 are connected to different bag-shaped parts 15.
After inserting into A and 16A, the other end parts 21 and 22 protruding toward the other end side can be easily joined by fixedly connecting them to each other at one place at the same time. Also, it does not require a heavy special jig, so it is easy to work. Get better.

Note that the wire member 19 is not only a pair of wire pieces 17 and 18 made by folding back the middle of one wire, but also a pair of wire pieces 17 and 18.
8 may be fixed to each other to form one V-shaped wire member.

In addition to the structure shown in FIG. 2, the means for fixedly connecting the other ends 21 and 22 of the wire member 19 may be, for example, a structure shown in FIGS. 3 to 8, if necessary. is also good. That is, the modified example shown as an exploded perspective view in FIG. 3 and as a sectional view taken along line A-A in FIG. 3 in a fixedly connected state in FIG. This structure uses a synthetic resin fixture 23 for fixed connection. This fixture 23 is provided with a recess 24 that receives the other ends 21 and 22 in a crossed state, and a protrusion 25 that locks the received other end 21 so that it does not come off. Projection 2 that locks the end portion 22 to prevent it from coming off
6 are provided on opposing surfaces.

In addition, a modified example shown as an exploded perspective view in FIG. 5 and a sectional view taken along line B-B in FIG. 5 in a fixedly connected state in FIG.
are simply bent in opposite directions on the same plane,
This other end is inserted into a recess 27 provided in a fixture 28 made of synthetic resin, and the bent ends of each of the other ends 21 and 22 are pressed against the inner wall surface of the recess 27 and locked. .

The modification shown in FIG. 7 is a further modification of the modification shown in FIG. The locking of the other ends 21 and 22 is made even stronger.

Further, in the modification shown in FIG. 8, the other ends 21 and 22 are made into a straight line shape, and these two other ends 21 and 22 are press-fitted into a recess 31 of a fixture 30 made of synthetic resin. be.

<<Effects of the invention>> As explained above, according to the vehicle seat trim cover terminal processing structure of the present invention, the joints at the terminals of the front trim cover part and the rear trim cover part that are joined to each other can be neatly finished. Value increases. Furthermore, since the joining work is simple, workability is improved and costs can be reduced.
