Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to an eccentric bezel for a trim cover for decorating a stitched portion of a trim cover such as a seat.

[Conventional technology]

For example, a trim cover that forms the surface of a seat of a vehicle or the like is configured by connecting a plurality of partial skins and the like having various shapes and thicknesses by stitching or the like. In such a trim cover, if the seam between the outer skins is exposed, the appearance quality of the seat is deteriorated. Also, the bending part,
The seating surface skin such as the scab is formed, for example, with an elastic material on the back surface. Therefore, an unnatural step is generated in the sutured portion with the town, etc.
It deteriorates the appearance quality.

Therefore, a bead is used to cover the seam of the stitched portion and to fill the step between the epidermis having different thicknesses to give the stitched portion a decorative feeling.

As a bead, for example, as shown in FIG. 5 (A), a hollow ball core main body 114 and a seam allowance portion 112 used at the time of sewing are integrally provided, and are folded from a soft resin material or the like. It is known that it can be freely bent. In such a bead 110, the seam allowance portion 112 is provided substantially on the center line of the bead main body 114, and the bead is formed in a symmetrical shape.

Such a bead 110 is, for example, interposed between the skin terminals 124 and 126 that are folded back to each other, and on the back surface of the trim cover,
The seam allowance portion 112 is attached to the suture portion 132 by integrally suturing it together with the end of the epidermis. In such a configuration, the outer skin ends are brought closer to the bead body direction due to the elasticity of the skins 124 and 126, the cushion body 130, etc., so that the seam 134 is covered by the bead body 114 and the suture portion 13
The step 2 is filled up, and the appearance quality of the sheet can be improved.

[Problems to be solved by the device]

However, since the seat trim cover is normally pulled under the elasticity of the seat cushion body 130 and the like, the stitched skin and the like are pulled in different directions. Particularly, as shown in FIG. 5 (A), between the outer skin 124 of the scab and the outer skin 126 of the gusset, the outer skin of the gusset is downward, that is, in the direction opposite to the bead body 114. , Is pulled under a large tensile force. Therefore, the bead body 114
There is a possibility that a gap 144 may be formed between the upper surface and the outer skin 126 of the gusset portion, and the seam 134 may be exposed from the gap. Since the exposure of the seam 134 deteriorates the appearance quality of the sheet, the known bead 110 does not sufficiently improve the appearance quality of the sheet.

Further, for example, as shown in FIGS. 5 (A) and 5 (B), when suturing epidermis having different thicknesses, usually, the epidermis of the stab part is used.
The position to be sewn is determined based on the thick epidermis such as 124. Therefore, the thin skin side such as the skin 126 of the gusset portion is bent at a position away from the ball core main body 114, and a gap 144 is likely to be formed between the skin and the ball core main body. Quality cannot be improved sufficiently.

An object of the present invention is to provide an eccentric bezel for a trim cover that suppresses the generation of a gap between the bead body and the outer skin and improves the appearance quality of a seat or the like.

[Means for Solving the Problems]

To achieve this object, according to the present invention, the bead body and the seam allowance portion are integrally formed, and the seam allowance portion extends in the tangential direction of the bead body.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, an eccentric bead 10 for a trim cover according to the present invention has, for example, a hollow ball core main body 14 and a seam allowance portion 12 used at the time of sewing, and is made of a soft material. It is made of a resin material and can be bent. And the seam allowance part 12
Are extended eccentrically with respect to the center of the core body 14.

As can be seen from FIG. 2, for example, a trim cover 20 of an automobile seat 18 has a plurality of skins forming each part of the seat surface, for example, a skin 22 of a bent portion, a skin 24 of a scab, and a town. The outer skins 26 and the like of the parts are formed, and each of the outer skins is connected to the adjacent outer skin by suture or the like. Here, for example, as shown in FIG. 3, the skin 22 of the bent portion and the skin 24 of the scabbard portion that form the seating surface of the seat 18 are designed to give the seated person a good feel and feel. The elastic material 28 is formed on the back surface.

Then, for example, a cushion body 30 made of fretan foam or the like placed on a seat frame (not shown)
The seat 18 is formed by covering the trim cover 20 with the trim cover 20.

Here, the eccentric bead 10 has, for example, as shown in FIG.
Interposed between the end of the epidermis 26 of the gusset and integrally stitching the seam allowance 12 with each epidermis,
An eccentric bead is provided on the seam portion 32 of the trim cover. At this time, the eccentric bead 10 is arranged so that the bead main body 14 is located, for example, in the direction of the skin 26 of the gusset. With such a configuration, as can be seen from FIG. 3,
Since the bead main body 14 sufficiently covers the outer skin 26 side of the gusset portion at the stitched portion 32, it is possible to suppress the occurrence of a gap between the outer skin of the gusset portion and the eccentric bead 10. Therefore, for example, even if the outer skin 24 of the scabbard portion and the outer skin 26 of the gusset portion are respectively pulled in different directions under the elasticity of the cushion body 30 of the seat, the seam 34 of the seam 34 on the outer skin side of the gusset portion is The exposure is prevented, and the appearance quality of the sheet 18 is improved.

Here, in the embodiment, as can be seen from FIGS. 1 and 3, the seam allowance portion 12 is formed on the tangent line of the bead body 14. According to this structure, the bead main body 14 has the seam allowance portion 12
Since the eccentricity is maximally eccentric, the epidermis side of the gusset portion at the suture portion 32 is sufficiently covered, and the exposed seam 34 is sufficiently covered. However, the seam allowance portion 12 need only be displaced from the center of the bead body 14, and is not limited to being tangential.

Further, in the embodiment, the suture portion 32 of the outer skin 24 of the scab and the outer skin 26 of the gusset are illustrated in FIG. 3 and specifically described, but the present invention is not limited to this and other skins The seam between,
For example, the same can be applied to the stitched portion between the skin 22 of the bent portion and the skin of the gusset portion.

Further, for example, as shown in FIG. 4, even in the case of the skins 36 and 38 having different thicknesses that are pulled in different horizontal directions, if the bead body 14 is located on the thin skin 38 side,
The occurrence of a gap between the outer skin and the thin outer skin is suppressed by the bead body, so that even in the stitched portion 40 of the outer skins 36 and 38 having different thicknesses, the exposure of the seam 42 can be sufficiently prevented.
The appearance quality can be improved.

It should be noted that the eccentric bead 10 of the present invention can be effectively used even in a sutured portion of the epidermis having a different tensile force. In such a case, the eccentric bead 10 is arranged and sewn so that the bead body 14 is positioned in the direction of the epidermis having a large tensile force. Even if the epidermis is strongly pulled from the bead, the ball core body can be sewn. Since it covers the sutured portion of the epidermis, it is possible to suppress the occurrence of a gap and prevent the seam from being exposed.

Further, in the embodiment, the bead main body 14 is formed hollow, but the present invention is not limited to this. For example, the bead main body may be formed solid. However, as in the example, the bead body
If 14 is hollow, the eccentric bead 10 can be made more bendable.

The above-described embodiments are for explaining the present invention, and are not intended to limit the present invention in any way, and all modifications and alterations within the technical scope of the present invention are also included in the present invention. Needless to say.

Although the trim cover bead of the present invention is suitable for automobile seats, the present invention is not limited to this, and can be applied to seats for trains, airplanes, ships, etc., for example.

Further, the present invention is not limited to the vehicle seat, and may be, for example, a conference room,
It may be applied to seats in movie theaters, offices, etc., or beds, sofas, etc.

[Effect of device]

As described above, in the eccentric bead for the trim cover according to the present invention, the seam allowance portion is formed integrally with the bead body and extends in the tangential direction of the bead body. Then, by covering the side such as the thin skin of the suture portion with the bead body,
It suppresses the generation of gaps between the skin and the bead body. Therefore, even if the skin is pulled in different directions under the elasticity of the cushion body of the seat, the seam is not sufficiently exposed at the stitched portion, and the appearance quality of the seat is improved.

In addition, if the bead body is located on the side of the epidermis with a large tensile force at the stitched portion of the epidermis having a different tensile force, even if the skin is pulled under a large tensile force, a gap will be generated by the bead body. It is suppressed and the seam is prevented from being exposed. Therefore, the eccentric bead of the present invention can be effectively used even in the sutured portions of the epidermis having different tensile forces.

If the seam allowance portion is provided on the tangent line of the bead body, the amount of eccentricity of the bead body is maximized, so that the bead body sufficiently covers the side seams such as the thin skin and the seam The exposure, and thus the appearance quality of the sheet, is improved more fully.
