Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of an automobile seat in which fine wrinkles are formed in the seat skin.

(Prior Art) Conventionally, in an automobile seat (front seat, rear seat) 1 as shown in FIG. 1, a flexible seat skin 2 has a widthwise raphe 3,
. . , 3 form a plurality of bulges 4, . . . , 4, and each bulge 4, .

However, in the conventional crease removal structure, as shown in FIGS. 2a and 2b, a skilled worker uses a gear sewing machine to draw the skin 2 against the pad 6 while inserting raphe lines 3, . . . , 3. Because I tried to pull it apart, it looked more like a dart had been removed than a wrinkle, which lowered the product value, and it was a hassle to pull it out by hand.
There was a problem that the wrinkles were not finished in an even pitch.

(Purpose of the invention) The present invention was made in view of the above-mentioned conventional problems, and the purpose is to provide an automobile seat that can form fine wrinkles with only a simple sewing operation. It is something.

(Structure of the invention) For this reason, the invention is constructed by sewing elastic pieces of rubber under tension over the entire length of each raphe line in the width direction of the flexible seat skin.

(Effects of the invention) According to the invention, a large number of fine wrinkles are formed at a uniform pitch on the seat skin due to the contraction of the stretched rubber piece, resulting in a good appearance and increased product value. Along with a significant improvement,
The work is easy as all you have to do is sew on the rubber pieces.
The wrinkle removal process can also be simplified.

(Example) As shown in FIGS. 3a and 3b, the widthwise raphe lines 3,...,
3, when forming a plurality of bulges 4,..., 4, the sheet is stretched in a stretched state by stretching the stretchable rubber strips 7,..., 7 over the entire length of each raphe line 3,..., 3. Sew on the back side of outer skin 2.

Thereafter, the seat skin 2 and pad 6 are sewn together via the rubber pieces 7, . . . , 7 along raphe lines 8, .

In this way, the rubber pieces 7,..., are attached to the raphe lines 3,...,3.
7 is sewn, a large number of small wrinkles 9, ..., 9 in the front and back direction are formed in each bulge 4, ..., 4 at a uniform pitch in the width direction due to the contraction of the rubber pieces 7, ..., 7. It becomes.

As shown in FIG. 4, when sewing the seat skin 2 and the pad 6, even if the rubber pieces 7, . 9 will be formed.

In each of the above embodiments, the fine wrinkles 9, . The seat feels softer than conventional dart-shaped ones that do not stretch.
