Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a vehicle seat trim cover end processing structure for fixing the end portion of the trim cover covering the pad material of the vehicle seat to the seat frame. .

<<Prior Art>> In a vehicle seat such as an automobile, force is applied to the seat cushion or seat back in a direction along its surface as the seat accelerates, decelerates, changes direction, etc. Therefore, in order to prevent the trim cover covering the surface of the seat pad material from peeling off under any force, it is necessary to fix the end of the trim cover to the seat frame. There is.

As shown in FIG. 5, for example, as an end treatment structure of such a trim cover, a metal ring 5 is attached to an end portion 4 of a trim cover 3 covering a pad material 2 supported by a substantially frame-shaped seat frame 1. A plurality of engagement holes 6 are provided with edges, and hooks 7 for hooking the engagement holes 6 of the terminal portion 4 are formed on the seat frame 1 side by cutting and raising, and the pad material 2 is pressed and compressed. It is known that the end portion 4 of the trim cover 3 is locked to the seat frame 1 at multiple locations by strongly pulling the end portion 4 of the trim cover 3 and locking the engagement hole 6 to the hook 7. .

Another structure is one in which the terminal portion and the seat frame are fixed using a plurality of clips such as hook rings.

《Problem that the invention attempts to solve》 However, in the former structure, the trim cover 3
A plurality of engagement holes 6 are provided for each terminal portion 4 of the
When the pad material is sequentially engaged with a plurality of hooks 7 provided on the seat frame 1 in correspondence with the engagement holes 6, the pad material remains until all the engagement holes 6 are engaged with the hooks 7. It is necessary to pull each terminal part 4 with a considerably strong force while the parts 2 are pressed and compressed. For this reason, there was a problem in that continuous work required physical strength and increased the burden on the worker.

In addition, the latter structure has the problem of poor workability as it is tiring and requires a lot of man-hours to attach multiple clips using a special jig such as a heavy hook linger.

Furthermore, in both the former and latter structures mentioned above, the end portion of the trim cover is pulled locally at the plurality of interspersed engagement sites, which may cause wrinkles or distorted shape of the end portion. I had a problem with it not looking very good.

The present invention was developed in view of these problems, and provides an average pulling force to the entire tip of the end portion that is pulled toward the seat frame, thereby eliminating wrinkles that tend to occur around the end portion, thereby creating a trim cover. To provide a trim cover terminal processing structure for a vehicle seat that improves the appearance of the trim cover and facilitates engagement and fixation of the trim cover and a frame.

<Means for Solving the Problems> In order to achieve this object, the present invention covers the pad material supported by the seat frame with a trim cover, and connects the end portion of the cover to the locking portion on the frame side. In the trim cover end processing structure for a vehicle seat, the locking portion is formed of a pair of locking pieces facing each other, and a rod-shaped member is commonly inserted into a hole provided in each of the locking pieces. The member has a stopper formed at one end thereof, a stopper having a slot at the other end, and a bag-shaped portion into which the rod-shaped member is inserted into the terminal portion, and the rod-shaped member is inserted into the other end. The structure is such that the end portion and the frame are fixed by being commonly inserted into the holes of both the locking pieces and the bag-like portion from the end side.

<<Operation>> With this configuration, the work of fixing the end portion of the trim cover and the frame can be done by aligning the bag-like portion on the trim cover side with each locking piece on the frame side, and then fixing the end portion of the trim cover to the frame. It is sufficient to simply insert the rod-shaped member into the hole of each locking piece. Therefore, the conventional fixing work in which multiple fixing operations are performed on the same terminal part is eliminated, and work efficiency is improved. At the same time, the terminal portion is evenly stretched by the rod-shaped member, so that wrinkles and the like do not occur.

<<Example>> Hereinafter, an example of the present invention will be described based on the drawings.

1 to 3 show an embodiment of the vehicle seat trim cover terminal processing structure according to the present invention, and FIG. 1 is an exploded perspective view of a schematic configuration of a seat cushion to which the same structure is applied Figure 2 is a perspective view of the main parts of the seat cushion, and Figure 3 is a perspective view of the main parts of the seat cushion.
FIG. 2 is a partially cutaway plan view showing a main part of the seat cushion shown in the figure.

1 to 3, the seat cushion 10 includes a substantially frame-shaped metal seat frame 12 to which a cushion spring 11 is attached, a pad material 13 supported on this frame 12, and a pad material 13 supported on the frame 12. The trim cover 14 covers the outer surface of the trim cover 14.

The seat frame 12 has a rectangular bottom wall 16 with an opening 15 in the center, and side walls 17 bent upward on each side of the bottom wall 16. A bent end wall 18 is formed so as to be bent downward. And the bottom wall part 16
side wall portions 17 at each position corresponding to each side wall portion 17.
A pair of locking pieces 19, 2 facing each other along the
0 is provided by cutting and raising a part of the bottom wall portion 16. In addition, the locking pieces 19 and 20 have holes 21 on opposing surfaces through which the rod-shaped member 22 is attached.
is formed. On the other hand, the trim cover 14 has side portions 23 and 2 that cover the four sides of the pad material 13.
This terminal unit 2 is attached to each terminal unit 27 of 4, 25, and 26.
A bag-shaped portion 28 is formed by folding back and sewing a part of 7. The bag-shaped portion 28 is configured such that the rod-shaped member 22 can pass through it.

As shown in FIGS. 2 and 3, the rod-shaped member 22 is made of relatively hard synthetic resin such as polyvinyl chloride, and is provided with a stopper 29 at one end and a slider at the other end. A stopper 31 in which a split 30 is formed is provided. When the rod-like member 22 is pushed into each hole 21 of the locking pieces 19 and 20 from the stopper 31 side, the stopper 31 is deflated inward by the slot 30 and inserted. Further, after insertion, it is locked with a stopper 31 to prevent it from coming off.

In the vehicle seat trim cover terminal processing structure configured in this way, when the terminal section 27 of the trim cover 14 is fixed to the frame 12, the terminal section 27 is fixed to the frame 12.
7 is strongly pulled so that the bag-shaped portion 28 is aligned with each hole 21 in the locking pieces 19 and 20 in a straight line. In this state, the rod-shaped member 22 is passed from the hole 21 on the locking piece 19 side to the hole 21 on the locking piece 20 side through the inside of the bag-shaped part 28.
1, the entire end portion 27 is pulled evenly by the rod-shaped member 22, and the end portion 27 is inserted into the frame 1.
It is fixed at 2.

Therefore, in this structure, the end portion and the frame 12 are fixed by passing one bar member 22 through the hole 21 of the pair of locking pieces 19, 20 and the bag-shaped portion 28 while the end portion 27 is pulled. Therefore, the engagement work for each terminal portion 27 can be easily completed only once.

Moreover, since the entire end portion 27 of each end portion 27 is pulled evenly by one rod-shaped member 22, wrinkles do not occur and the appearance is good, and there is no need for a heavy dedicated jig as in the past. Therefore, the burden on the worker is also reduced.

In addition, in the above embodiment, a structure was shown in which a stopper 31 was provided from the beginning on the insertion end side of the rod-shaped member 22, but as shown in FIG. The part 32 may be heat caulked or cold caulked to prevent it from coming off.

<<Effects of the invention>> As is clear from the above explanation, according to the present invention, the holes of the pair of locking pieces that are pulled once for each terminal part and lined up in a straight line and the bag-like part of the terminal part. Each end of the trim cover can be fixed to the frame simply by inserting one common rod-shaped member, improving work efficiency, and the appearance is improved since wrinkles do not occur at each end. In addition, the burden on the worker is reduced because heavy specialized jigs are not used.
Furthermore, work efficiency is improved.
