In other words, there is no need to attach separate clip members individually using special tools, as was conventionally used, and the locking piece of the joining member provided in advance on the trim cover part can be attached to the other cover part. Since it is only necessary to connect the terminals at the joints, the joining work between the terminals becomes easy.

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

FIG. 1 is a sectional view showing a schematic configuration of a seat back 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, a seat back 11 includes a pad material 12 and a seat frame 13 to which this pad material 12 is attached.
and a trim cover 14 that covers the pad material 12. 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 has a front trim cover part 15 and a rear trim cover part 16.
are joined in advance into a bag shape, and pad material 1 is placed inside this bag shape.
It can be put on to store 2. Further, a bag-shaped portion 16A is formed at the end of the rear trim cover portion 16 by sewing or other joining means, and a relatively rigid metal wire 17 is inserted into the bag-shaped portion 16A. ing. The bag-shaped portion 16A has a plurality of notches 1 cut from the end thereof.
6B, a part of the wire 17 is exposed in this notch 16B, and a hole-shaped engaging part 18 is formed by the notch 16B and the exposed part of the wire 17. On the other hand, a joining member 19 is provided at the end of the front trim cover part 15 in correspondence with the engaging part 18 of the rear trim cover part 16. This joining member 19 is formed of a fixing piece 20 and a locking piece 21, each molded from a synthetic resin material. Fixed piece 2
0 is fixed at one end to the end of the cover portion 15, and the other end is hingedly engaged with one end of the locking piece 21 via the pivot shaft 22. Furthermore, a through hole 23 is formed in the surface of the fixing piece 20. Further, the locking piece 21 is elastic and formed in a substantially C-shape, and a locking protrusion 24 that is press-fitted into the hole 23 of the fixed piece 20 is provided on the outer surface of the free end.

When joining the ends of the front trim cover part 15 and the rear trim cover part 16 to each other,
First, with each terminal drawn toward each other, press the locking piece 21.
The free end of is inserted into the engaging portion 18 (see FIG. 3), and further rotated to a position where the protrusion 24 corresponds to the hole 23 of the fixing piece 20. When the locking piece 21 is pushed from the outside toward the fixed piece 20 with a finger or the like at this rotation end, the protrusion 24 is press-fitted into the hole 23, and as a result, the free tip of the locking piece 21 is fixed to the fixed piece 20. (See Figure 4). In this state, the engaging piece 21 and the engaging part 1
8 are in a chain connection state, and each cover part 15 and 16
terminals are now connected to each other.

Therefore, in this structure, the engagement piece 21 that passes through the engagement portion 18 does not use a clip member that is attached with a special jig such as a heavy hook ringer, which is used in the conventional terminal processing structure. The ends of each cover part 15, 16 can be joined by simply pressing the fixing piece 20 against the fixing piece 20, improving work efficiency. Moreover, the joining member 19 is fixed in advance to the end of the front trim cover section 15, and unlike the conventional end processing structure, separate members are not attached individually, making parts management easier and further improving work efficiency. do.

In the above embodiment, the joining member 19 is attached to the front trim cover section 15, and the joining member 19 is attached to the rear trim cover section 16.
Although a structure in which the engaging portions 18 are respectively provided is shown, the arrangement may be reversed. Also, joining member 1
The number of attachment portions 9 and engaging portions 18 may be determined as required. Furthermore, in the joining member 19, a fixing piece 20 that pivotally supports each engagement piece 21 is formed into a single plate shape and placed along the end.
A plurality of engaging pieces 21 may be attached using the same as a common fixing piece.

<<Effect of the invention>> As explained above, according to the trim cover end processing structure for a vehicle seat of the present invention, the hole-shaped engagement portion provided at the end of one trim cover part is connected to the end treatment structure of the trim cover part of the other trim cover part. By inserting the locking piece of the joining member provided at the end and fixing the rotating end of the locking piece to the fixed piece, the engaging part and the locking piece are chained together, and the locking piece is connected between the ends of each trim cover part. Since these are connected to each other, the locking piece of the joining member can be connected to the engaging part provided on the other cover part without using a special tool, and the connection between the terminals can be easily performed. Joining work becomes easier.

Further, the joining member has a fixed piece fixed to an end of the trim cover portion, one end of which is pivotally supported by the fixed piece, and the other end of which rotates through the engaging portion and is fixed to the fixed piece at the rotating end. The locking piece is configured to be chained to the engaging part, so that the locking piece can be inserted into the hole-shaped engaging part by pointing the locking piece toward the fixing piece and pushing it with a finger or the like. Since the free end of the locking piece is fixed, installation work is very easy and requires less work force.

Furthermore, in the process of fixing the end of the trim cover part, the joining member is configured so that the inner wall of the locking piece comes into pressure contact with the wire and pulls the end of one cover part, so that it becomes chain-bonded with the engaging part. With this configuration, it is possible to completely prevent the occurrence of wrinkles between both covers after the ends of both covers are joined.
