A plurality of skin materials including the second skin material 12 are sewn together to form a plurality of skin materials. As the skin material, for example, leather, woven cloth, non-woven fabric and the like are used. The trim cover 5 may be formed of one type of skin material, or may be formed of a plurality of types of skin material that differ depending on the site.

FIG. 2 shows a sutured portion between the first skin material 11 and one of the second skin materials 12.

The first skin material 11 and the second skin material 12 are sewn together along a suture line L extending in the front-rear direction of the seat. The suture portion 13 between the first skin material 11 and the second skin material 12 is provided with a hanging tool 14 for suspending the suture portion 13 to the cushion pad of the seat cushion 2.

In this example, the hanging tool 14 is composed of a hanging bag 15 formed in a tubular shape and a wire 16 inserted through the hanging bag 15. The seam allowance 17 of the first skin material 11 and the seam allowance 18 of the second skin material 12 formed on the stitched portion 13 are overlapped with each other, and the hanging bag 15 has the seam allowance 18 of the overlapped seam allowances 17 and 18. It is arranged on the side and overlapped with the seam allowances 17 and 18. Then, when the first skin material 11 and the second skin material 12 are sewn together along the sewn line L, the hanging bag 15 is attached to the first skin material 11 and the second skin material 12 along the sewn line L. It is sewn.

Further, the stitched portion 13 is provided with a flexible protective material 19, and in this example, the protective material 19 is composed of a seam allowance 17 of the first skin material 11. The seam allowance 17 of the first skin material 11 is formed wider than the seam allowance 18 of the second skin material 12, and when the seam allowances 17 and 18 are vertically hung from the seam portion 13, the seam allowance 17 is larger than the seam allowance 18. Also extends downward, and similarly extends downward from the hanging tool 14 vertically hung from the suture portion 13, and the protective material 19 formed by the seam allowance 17 extends downward from the hanging tool 14. ing.

The seam allowance 18 of the second skin material 12 may be formed wider than the seam allowance 17 of the first skin material 11, and the protective material 19 may be composed of the seam allowance 18, but the seam allowances 17 and 18 that are overlapped may be formed. When the hanging bag 15 is arranged on the seam allowance 18, it is preferable that the seam allowance 17 on the side opposite to the seam allowance 18 on which the hanging bag 15 is arranged is formed wide, and the protective material 19 is composed of the seam allowance 17. .. When the hanging bag 15 is sewn to the seam allowances 17 and 18, the seam allowance 18 is arranged on the seam allowance 17, and the hanging bag 15 is superposed on the seam allowance 18, but the relatively narrow seam allowance 18 is relative. The wide seam allowance 17 does not cover the seam allowance 17 and facilitates sewing.

The protective material 19 is for alleviating the contact between the back surfaces of the first skin material 11 and the second skin material 12 and the wire 16 of the hanging tool 14 and suppressing the wear of the first skin material 11 and the second skin material 12. belongs to. The hanging tool 14 is provided over substantially the entire length of the seat cushion 2 in the front-rear direction of the seat, whereas the protective material 19 is at least the central portion of the seat cushion 2 in the front-rear direction of the seat, as shown in FIG. That is, it is provided in a portion where the load of the seated occupant is relatively concentrated. The protective material 19 may be dispersedly provided at a plurality of locations in the central portion of the seat cushion 2 in the front-rear direction of the seat, or may be provided over a substantially overall length including the central portion of the seat cushion 2 in the front-rear direction of the seat. You may.

3 and 4 show a state in which the suture portion 13 between the first skin material 11 and the second skin material 12 is suspended from the cushion pad of the seat cushion 2.

The cushion pad 6 of the seat cushion 2 is formed with a hanging groove 7 extending in the front-rear direction of the seat along the suture portion 13 between the first skin material 11 and the second skin material 12 of the trim cover 5, and is hung. A wire 8 as a holder is provided at the bottom of the groove 7. A substantially C-shaped hog ring 20 is crimped around the outer circumference of the wire 16 of the hanging tool 14 and the wire 8 of the hanging groove 7, and the hanging tool 14 is inserted into the hanging groove 7. In the rolled state, it is locked to the wire 8 via the hog ring 20. As a result, the suture portion 13 provided with the hanging tool 14 is suspended in the hanging groove 7.

With the sewn portion 13 suspended in the hanging groove 7, the protective material 19 formed by the seam allowance 17 of the first skin material 11 is also inserted into the hanging groove 7, and is a hanging tool. It is arranged so as to overlap the wire 16 on the opening 7a side of the suspension groove 7 with respect to the wire 16 of the 14th. As described above, when the hanging tool 14 and the protective material 19 are vertically hung from the suture portion 13, the protective material 19 extends downward from the hanging tool 14, and the edge portion 19a of the protective material 19 is, for example, It is rolled up and packed in the hanging groove 7.

FIG. 4 shows a state in which the occupant is seated on the seat 1 and the cushion pad 6 of the seat cushion 2 is compressed.

As the cushion pad 6 is compressed, the groove depth of the hanging groove 7 becomes smaller, and the wire 16 of the hanging tool 14 relatively floats toward the opening 7a of the hanging groove 7. The surfaced wire 16 approaches the back surfaces of the first skin material 11 and the second skin material 12 covering the opening 7a, and when the groove depth of the suspension groove 7 before compression is relatively small, the wire 16 Reaches the back surfaces of the first skin material 11 and the second skin material 12.

Here, the protective material 19 is arranged so as to overlap the wire 16 on the opening 7a side of the hanging groove 7 with respect to the wire 16 of the hanging tool 14. Even if the wire 16 reaches the back surfaces of the first skin material 11 and the second skin material 12 covering the opening 7a due to the compression of the cushion pad 6, the wire 16, the first skin material 11, and the second skin material 12 A protective material 19 is interposed between the back surface of the wire 16 and the back surface of the first skin material 11 and the second skin material 12 is prevented from being in direct contact with each other. As a result, it is possible to suppress wear and tear of the first skin material 11 and the second skin material 12 even when the occupant repeatedly sits down and leaves the seat, and the durability of the trim cover 5 can be improved.

In this example, when the hanging tool 14 and the protective material 19 are vertically hung from the suture portion 13, the protective material 19 extends downward from the hanging tool 14, and the edge portion 19a of the protective material 19 is, for example, It is rolled up and packed in the hanging groove 7. Therefore, the cushioning action of the protective material 19 interposed between the wire 16 and the back surfaces of the first skin material 11 and the second skin material 12 is enhanced, and the first skin material 11 and the second skin material 12 are worn or torn. It can be further suppressed.

As shown in FIG. 5, both the seam allowance 17 of the first skin material 11 and the seam allowance 18 of the second skin material 12 are extended below the hanging tool 14, and the seam allowances 17 and 18 constitute the protective material 19. You may. This also enhances the cushioning action of the protective material 19, and further suppresses wear and tear of the first skin material 11 and the second skin material 12.

Further, in this example, the protective material 19 is composed of the seam allowance 17 of the first skin material 11, and it is possible to save the trouble of joining another protective material to the sewn portion 13. However, as shown in FIG. 6, the protective material 19 is configured separately from the first skin material 11 and the second skin material 12, and may be sewn to the seam allowances 17 and 18. When the protective material 19 is formed separately from the first skin material 11 and the second skin material 12, the degree of freedom of the material used for the protective material 19 is increased. Therefore, as the material of the protective material 19, for example, a material having better wear resistance than the first skin material 11 and the second skin material 12 can be used, and the durability of the trim cover 5 can be further enhanced.

The contact between the wire 16 and the back surfaces of the first skin material 11 and the second skin material 12 due to the compression of the cushion pad 6 is more likely to occur as the groove depth of the hanging groove 7 before compression is smaller, and the protective material 19 is used. The protection of the first skin material 11 and the second skin material 12 that have been used is particularly useful when the groove depth of the hanging groove 7 is 20 mm or less. Considering the general diameters of the wires 8 and 16, the groove depth of the hanging groove 7 is preferably 10 mm or more.

Up to this point, the present invention has been described by taking the trim cover 5 of the seat cushion 2 as an example, but the present invention can also be applied to the trim cover of the seat back 3 shown in FIG. Further, the present invention can be applied not only to seats mounted on vehicles such as automobiles, but also to seats for vehicles other than vehicles such as aircraft and ships.
