Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a decorative bead provided on the skin of a cushion pad in automobile seats, sofas, beds, etc. used as furniture.

(Prior Art) Conventionally, as shown in FIG. 7, there is a bead 3 made of a slightly soft synthetic resin, in which a fin 2 for skin suturing is linearly projected from a bead 1 having a circular cross section.

Then, a skin 4 made of synthetic leather, soft resin, etc. is sewn to both sides of the fin 2 of the bead 3 to form a seat cover 5 (see Fig. 8), and this seat cover 5 is sewn by a predetermined method. The surface of the pad 6 made of a cushion material was coated under tension.

(Problem to be Solved by the Invention) By the way, when the seat cover 5 is covered as described above, the fin 2 of the bead 3 is in a state of protruding toward the pad 6 as shown in FIG. Therefore, depending on the way the seat cover 5 is stretched, the shape of the surface of the pad 6, etc., the fin 2 can be positioned downward as shown in FIG. 9 or upward as shown in FIG. 10. In response to the difference in how the fin 2 is accommodated, the ball portion 1 is fixed at different positions as shown in the figure.

In this way, as shown in FIG. 6, the bead 3 provided on the sheet 7 is partially as shown in FIG. 9, and in other parts as shown in FIG.
By being fixed in the state shown in Figure 0, the beading edge 3 as a whole becomes meandering 8, resulting in a problem of poor appearance as a decoration.

Therefore, the object of the present invention is to prevent such meandering at the bead edge.

(Means for Solving the Problems) In order to solve the above problems, this invention is a decorative bead provided along the seam of the skin for covering pads of automobile seats, etc. The bead includes a bead with a predetermined cross-sectional shape and a fin protruding from the bead, and is integrally molded from synthetic resin, and the fin is attached to the epidermis on the proximal side to be sutured to the epidermis. The joint portion and the seating portion on the distal end side form a substantially L-shaped cross section.

(Function) In the bead configured as described above, when the epidermis is sewn to both sides of the epidermal joint of the fin, which has an approximately L-shaped cross section and is projected from the bead, to cover the pad, the epidermal joint is covered with a pad. It becomes a state in which it protrudes toward the surface of. At this time, the seating part provided at the tip of the fin so as to be bent at 90° or a predetermined angle similar to this with respect to the epidermal joint becomes almost parallel to the surface of the pad, making surface contact with the surface of the pad. Sit in a stable position.

Therefore, the fixed position of the ball portion remains constant without meandering.

(Example) Next, a first example of the present invention will be described based on FIGS. 1 to 3.

The bead 9 (see FIG. 2) is an elongated member integrally molded using a synthetic resin material soft enough to be penetrated by a sewing needle. The bead edge 9 consists of a bead portion 10 having a circular cross section and a single fin 11 protruding from the bead portion 10.

The fin 11 is formed into a bent cross-sectional shape having an epidermal joint portion 12 on the proximal side and a seating portion 13 on the distal side. As shown in FIGS. 2 and 3, the skin joint portion 12 protrudes from the ball portion 10 along the radial direction, and is formed to have a width as small as possible so that a skin 14, which will be described later, can be sewn to both sides of the skin joint portion 12. There is.
The seating portion 13 is bent and protruded from the tip of the skin joint portion 12 at an angle of 90°, and is formed to have a width that allows it to sit stably on the surface of a pad 15, which will be described later.

The present embodiment is constructed as described above, and includes, for example, an automobile seat 1 as shown in FIG.
6 is used as follows:

That is, first, the skin 14 is sewn to the skin joint portion 12 of the fin 11 at the bead 9 from both sides to form a bag-shaped seat cover 17. Then, the seat cover 17 is applied under tension to the surface of the pad 15 made of a cushion material (sponge, etc.) by a predetermined means (see FIG. 3).

During such work, the skin joint 12 receives the tensile force of the skin 14 from both sides and protrudes toward the pad 15. Therefore, since the seating part 13 is positioned substantially parallel to the surface of the pad 15, the lower surface of the seating part 13 is seated in surface contact with the surface of the pad 15. As long as there are no abnormal variations in the way the skins 14 on both sides are stretched or the shape of the surface of the pads 15 during the covering operation, the above-mentioned seating condition will not be affected. Due to the stability of the seated state of the fin 11, the fixed position of the ball portion 10 becomes constant, and the meandering of the ball edge 9 is prevented (see FIG. 1).

Next, a second embodiment of the present invention will be described based on FIG. 4.

In the bead 18 of this embodiment, a skin joint 20 protrudes from the ball 19 along the tangential direction, and a seating part 21 extends outward from the tip of the skin joint 20.
is bent and protruded at an angle of approximately 90°.

The configuration, operation, and effects of this embodiment other than the above are the same as those of the first embodiment.

Next, a third embodiment of the present invention will be described based on FIG.

In the bead 22 of this embodiment, the skin joint 24 protrudes from the bead 23 along the tangential direction, and the seating part 25 extends inward from the tip of the skin joint 24.
is bent and protruded at an angle of approximately 90°.

The configuration, operation, and effects of this embodiment other than the above are the same as those of the first embodiment.

(Effects of the invention) As described above, according to this invention, the ball part and one fin are integrally molded from synthetic resin, and the fin is connected to the epidermal joint part on the proximal end and the distal end. It is formed into a substantially L-shaped cross section by the side seating portions, and such a very simple structure can effectively prevent meandering of the ball portion.
