Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a skin tension structure in a seat bag such as an automobile seat.

(Prior Art) In a seat back for an automobile seat, as shown in FIG. 3, a cover set wire e is inserted through the lower side connecting portion d of the back side portion c of the skin b covering the seat back body a in the vehicle width direction; The rear side connection part g of the lower surface side part f is connected to the cover set wire h, which is inserted in the vehicle width direction, using a hog ring i at the lower part of the back of the seat bag body a, so that the skin b
is being set up.

(Problem to be solved by the invention) However, in the above conventional example, since the lower side connection part of the back side part is pressed against the hog ring by the skin in tension, the lower side connection part d of the back side part is pressed against the hog ring as shown in FIG. There is a problem in that the part corresponding to the hog ring i is lifted up by the hog ring i, and a local swell occurs in the lower side connection part d, resulting in an unsightly appearance.

Further, due to the swell of the lower side connecting portion d, vertical wrinkles are generated in the entire back side portion c of the skin b, which further deteriorates the appearance.

In view of the above-mentioned problems, the present invention has been developed to create a tensioning system for the skin on the seat back that can avoid the lower connection part of the back side of the skin from rising due to hog ring, and can eliminate vertical wrinkles on the back side of the skin. The purpose is to provide structure.

(Means for Solving the Problems) In order to achieve the above object, the present invention hogs the lower side connection part of the back side part of the skin covering the seat bag body and the rear side connection part of the lower side part at the lower part of the back side of the seat bag body. In the skin tension structure of a seat bag that is fastened using a hog ring, a convex part that backs up the lower side connection part is provided at the part corresponding to the lower side connection part of the pad of the seat bag body, and the amount of protrusion of this convex part is determined by adjusting the amount of protrusion of the hog ring. The pad is characterized by being set to such an extent that the entire back side part can be tensioned without wrinkles when set, and a recess for accommodating the hog ring is formed below the projection of the pad.

(Function) According to the above configuration, the convex portion provided on the pad of the seat bag body backs up the lower side connecting portion of the back side portion of the skin in tension, and the concave portion below the convex portion accommodates the hog ring. As a result, the entire lower side connecting portion can be lifted by the convex portion, while the hog ring can be accommodated in the recess, so that the portion of the lower side connecting portion corresponding to the hog ring is lifted by the hog ring and the local area is lifted up by the hog ring. You can avoid getting excited. In this manner, by avoiding local swelling of the lower side connecting portion and lifting the entire lower side connecting portion, it is possible to prevent the occurrence of vertical wrinkles as in the conventional example on the entire back side portion of the epidermis.

〔Example〕

1 and 2 show an embodiment in which the present invention is applied to a seat back for an automobile seat.

Seat bag body 1 is seat bag frame 2
and seat back pad 3. The skin 4 covering the seat bag main body 1 is composed of a full surface side part 5 covering the front surface of the seat bag main body 1, a back side part 6 covering the back surface, and a lower surface side part 7 covering the lower surface. The front side part 5 and the back side part 6 are
The upper edge and both side edges of the seat bag body 1 are sewn together with a welt 8 in between. Front side part 5
and the lower surface side portion 7 are sewn together at the lower front surface of the seat bag body 1. The back surface side portion 6 and the lower surface side portion 7 are connected at the lower back surface of the seat bag body 1 using a hog ring 9.

A hanging cloth 11 for inserting and holding the cover set wire 10 in the vehicle width direction is sewn to the back side of the lower side part of the rear side part 6, and a lower side connecting part 12 with the lower side part 7 is sewn.
is formed. The lower side portion of the back side portion 6 extends slightly below the lower side connecting portion 12, and forms a cover portion 13 that covers the connection portion with the lower side portion 7. On the other hand, the folded edge of the rear side portion of the lower surface side portion 7 is sewn to form a rear side connecting portion 15 through which the cover set wire 14 is inserted and held in the vehicle width direction.

A portion of the seat back pad 3 corresponding to the lower side connecting portion 12 is provided to protrude toward the rear side, and a convex portion 16 for backing up the lower side connecting portion 12 is formed in the vehicle width direction. Further, a recess 17 for accommodating the hog ring 9 is formed below the protrusion 16 of the seat back pad 3. The recess 17 may be formed over the entire length of the protrusion 16 in the vehicle width direction, or may be formed only at a portion corresponding to the hog ring 9.

In the above configuration, the lower side connection part 12 of the back side part 6 of the epidermis 4 and the rear side connection part 15 of the lower side part 7
When connecting, the back surface of the lower side connecting portion 12 is brought into contact with the convex portion 16 of the seat back pad 3. The cover set wire 10, which is inserted and held by the hanging cloth 11 of the lower side connecting portion 12, is positioned slightly below the convex portion 16, that is, above the concave portion 17 of the seat back pad 3. On the other hand, the cover set wire 14, which is inserted and held by the rear side connecting portion 15 of the lower surface side portion 7, is positioned in the lower part of the recess 17.

In this state, both cover set wires 10 and 14 are fixed using a plurality of hog rings 9. epidermis 4
becomes a tension state, and the lower side connection part 1 of the back side part 6
2 comes into pressure contact with the convex portion 16 of the seat back pad 3. Thereby, the lower side connecting portion 12 can be evenly backed up by the convex portion 16, so that the entire back side portion 6 can be stretched without wrinkles. In addition, the hog ring 9 and both connecting parts 12 and 15 are attached to the cover part 13 of the back side part 6.
Since it is covered with

Further, since the hog ring 9 is accommodated in the recess 17 of the seat back pad 3, the lower side connecting portion 1
I will never lift 2. Therefore, the lower side connection part 1
It is possible to avoid local bulges from occurring in 2. In this case, there is no problem even if the hog ring 9 is in contact with the wall surface of the recess 17.

The present invention can be configured in various ways other than those shown in the above embodiments.

For example, the specific configurations of the seat bag body and the skin are not limited to those shown in the above embodiments, and can be designed as appropriate.

(Effect of the invention) According to the invention, since the lower side connection part of the back side part can be backed up by the convex part of the seat back pad, the back side part can be tightened without wrinkles, and the Since the hog ring that connects the lower side connection part and the rear side connection part of the lower side connection part can be accommodated in the recess of the seat back pad, this hog ring lifts up the lower side connection part and creates a local bulge. This can be avoided.
