Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for closing an opening of a bag having a cushion body inserted therein.

[0002]

2. Description of the Related Art Generally, the backrest of a vehicle seat is
The cushion body is covered with a cover made of a predetermined skin material. In the back portion, a bag-shaped cover and a cushion body are formed independently, and after inserting the cushion body from the lower opening of the cover,
Some are manufactured by closing the openings of the cover.

Conventionally, when closing the opening of the cover,
A person holds both sides of the edge of the opening with his / her hand, and while pushing the cushion body inward, pulls the edge of the opening by hand and pulls it to bring both sides of the edge closer to each other, and then connects them by an appropriate connecting means. It was

[0004]

By the way, since the backrest portion of the vehicle seat has the lumbar support portion and the side support portion, it is uneven in a complicated manner, and the cover and the cushion body are formed in conformity with the shape. Then, in order to improve the appearance of the backrest as a finished product, the cover and the cushion body have almost the same size, or the cushion body is formed slightly larger, and when the cushion body is inserted into the cover. There is no gap between them.

Therefore, after inserting the cushion body into the cover, a considerable amount of force is required for the work of retracting the cushion body to the deep end. Further, similarly, the work of pulling the both sides of the edge portion of the opening of the cover toward each other requires a considerably large force. Furthermore, these operations required multiple workers. The present invention has been made in view of the above-mentioned problems of the conventional techniques, and an object of the present invention is to provide a method for closing the opening of a bag, which can improve workability and productivity. Where it is.

[0006]

The present invention has been made in order to achieve the above-mentioned object, and its gist is to provide a method for closing the inside of a cushion body in which a cushion body is inserted. Hang the inserted bag with the opening facing up and hook one side of the edge of the opening on the hanging tool,
Next, the other side of the edge portion of the opening is pulled toward the one side so that the one side of the edge portion and the other side are irremovably coupled via a coupling tool. There is a matching method.

[0007]

The cushion body can easily reach the inner end of the bag by its own weight by suspending the bag in which the cushion body is inserted with its opening facing upward. If a downward force is applied to the cushion body in this state, the effect is more certain. Since one side of the opening edge of the bag hooked on the hanging device is pulled downward by the weight of the cushion body, pulling only the other side of the opening edge allows the other side to Can be pulled to one side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings from FIG. 1 to FIG. It should be noted that this embodiment is a mode in which the "method for closing the opening of the bag" according to the present invention is applied to the manufacture of the backrest portion of the vehicle seat. Figure 3
As shown in FIG. 1, the backrest portion 1 of the vehicle seat includes a bag-shaped cover (bag) 10 formed in a predetermined shape, and a cushion body 2 formed in the predetermined shape and inserted into the cover 10.
It is composed of 0 and 0.

The cover 10 has an opening 11 in its lower portion. Reinforcing parts 12 and 13 are provided at the front and rear of the edge of the opening 11 in the cover 10. A wire 14 is inserted through the reinforcing portions 12 and 13 as shown in FIG. FIG. 3 shows a state immediately after inserting the cushion body 20 into the cover 10 through the opening 11 and before closing the opening 11. At this time, the cushion body 20 has not yet reached the back end of the cover 10.

The opening 11 is closed as follows. First, as shown in FIG. 1, prepare a hanger 30,
The hanging tool 30 is fixed to the wall 40 or the like. Hanging equipment 30
For example, as shown in FIG. 4, both ends 31 and 32 of a substantially U-shaped iron bar are sharpened and slightly bent upward as shown in FIG. Reference numeral 33 in the drawing is a stopper.

As shown in FIGS. 1 and 4, the backrest 1 is turned upside down so that the opening 11 of the cover 10 is directed upward, and the rear end of the reinforcing member 13 is provided with the tip 31 of the suspender 30.
As shown in FIG. 2, the wire 14 in the reinforcing portion 13 is hung on the tips 31 and 32 of the backrest portion 1 to penetrate the back portion 1.
Hang.

In this way, the backrest portion 1 is attached to the suspension 3
When it is hung at 0, the cushion body 20 advances to the innermost end of the cover 10 due to its own weight. It should be noted that if the cushion body 20 is pushed down by hand, it is possible to more surely reach the back end of the cover 10.

Next, from this state, the front reinforcement portion 12 of the cover 10 is grasped by hand and pulled toward the reinforcement portion 13 while pulling upward. And the reinforcement part 1
The wire 2 (not shown) of the reinforcing portion 12 is hooked on both ends 31, 32 by penetrating the both ends 31, 32 of the suspender 30. During this work, the reinforcement body 13 has a cushion body 20.
Since the weight of the reinforcing member 13 acts on the reinforcing member 13, the reinforcing member 13 is not lifted and separated from the hanger 30.

As described above, by hooking the reinforcing portion 12 on the suspending tool 30, both the reinforcing portions 12 and 13 can be positioned adjacent to each other, and thereafter, this state can be maintained without human intervention. You can Therefore, the subsequent work of closing the opening 11 can be performed very easily. The opening 11 is closed by connecting the reinforcing portions 12 and 13 with a hog ring device (connector) 50 at predetermined intervals, as shown in FIG. The means for closing the opening 11 may be a means other than the hog ring device.

In this way, the cushion body 20 is covered by the cover 1.
It can be easily pushed into the rear end of 0, and the opening 11 of the cover 10 can be easily closed. Moreover, these operations can be performed by almost one person, and workability and productivity are improved.

The present invention is not limited to the above embodiment and various modes can be adopted. For example, in the above-described embodiment, the reinforcing portion 12 is also hooked on the hanging tool 30, but the reinforcing portion 12 does not necessarily have to be hooked on the hanging tool 30. Further, the shape of the hanging tool 30 is not limited to that of the above-described embodiment. Further, the application target of the "method for closing the opening of the bag" according to the present invention is not limited to the backrest portion of the vehicle seat, but can be applied to other things.

[0017]

As described above, according to the present invention, the opening of the bag can be closed very easily, and the excellent effect of improving workability and productivity can be obtained. .
