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. 5, in a conventional vehicle seat, a pad material 2 of a seat 1 is 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 both bag-like parts 4A and 5A are connected at these ends using a special jig such as a hook ringer. They are joined by a plurality of clips 7 attached at predetermined intervals, and this joint is further covered by an extension 5B of the rear trim cover 5 to hide the clips 7. 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, the terminal processing structure of the trim cover in the conventional vehicle seat has a plurality of clips 7.
It is necessary to join them using a special jig, but this work is tiring because the special jig is heavy, and if skill is not required, there is a risk of damage or injury. Therefore, there are problems of poor workability and high costs. Moreover, if the parts are simply joined using the clip 7, the appearance will be poor when the joined parts are exposed by folding down the seat or the like. 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 5
B is generally arranged in a rolled-up manner, so when the seat is folded forward, the extension part 5B is turned over and the clip 7 is visible, and the tip of the extension part 5B is wavy, which does not look very good. There was a problem.

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. We provide a trim cover end processing structure for vehicle seats that improves workability and reduces man-hours, and at the same time prevents the appearance from being spoiled even if joints are not covered with trim cover extensions. 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-like part provided at the end of each trim cover part, and a pair of locking pieces inserted into each bag-like part from one end side. and a pair of locking pieces that are inserted from the other end side and engage with each other at positions where they abut the locking pieces of the first U-shaped member. and a second U-shaped member having a second U-shaped member, and the first and second U-shaped members are engaged and connected to each other within the bag-shaped part to press the bag-shaped part to each other and close the ends. It is configured as follows.

<<Operation>> According to the present invention, the first U-shaped member and the second U-shaped member
By engaging and connecting each pair of locking pieces of the letter-shaped member with the opposing locking pieces of each bag-shaped part, the ends of the front trim cover part and the rear trim cover part are joined and closed. . Therefore, the joining operation only requires inserting the first U-shaped member and the second U-shaped member from opposite sides of each bag-shaped portion. Further, at the joint, only a single boundary line created by the bag-like parts abutting against each other is visible.

<<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. In one method, 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 then covering 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 section 15 and the rear trim cover section 16, there are bag-shaped sections 15, respectively.
A and 16A are formed by sewing or other joining means. And the trim cover 14 is padded material 1
2, the bag-like parts 15A, 16A are joined to each other by a joining means at the terminal bag-like parts 15A, 16A and closed. This bag-shaped portion 15
The joining means for joining A, 16A is a first member inserted into each bag-shaped part 15A, 16A from opposite sides.
It consists of a U-shaped member 17 and a second U-shaped member 18. The first U-shaped member 17 has a pair of locking pieces 20 and 21 made by folding a pipe-shaped member from the intermediate portion 19. Both locking pieces 2
0 and 21 are parallel to each other, and when inserted into different bag-like parts 15A and 16A, a distance is maintained such that the bag-like parts 15A and 16A abut each other. Further, a pair of engagement holes 22 are provided at each tip of both the locking pieces 20 and 21. On the other hand, the second U-shaped member 18 has a pair of locking pieces 24 and 25 formed by folding back from the intermediate portion 23. The locking pieces 24 and 25 are parallel to each other, and the first
An interval corresponding to the dimension between the locking pieces 20 and 21 of the U-shaped member 17 is maintained. Also, both locking pieces 2
4 and 25 are press-fitted into respective locking pieces 20 and 21 of the first U-shaped member 17 to form engagement holes 2.
A pair of protrusions 26 that are fitted and locked to 2 are integrally formed. The insertion surface of the protrusion 26 is formed with a tapered portion 26A to facilitate fitting and insertion, and the engaging portion 26B is formed substantially vertically.

When joining the ends of each trim cover part 15, 16 to each other, first, each bag-shaped part 15A, 16
