Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of manufacturing a sun visor body installed in a vehicle interior.

(Prior art) Conventionally, when manufacturing the sun visor body, the sixth
As shown in the figure, two skin materials h are sewn with a sewing machine so that the upper part is open, and then punched and cut to form a bag body f. After inserting the body p, a portion slightly inward of the opening edge f1 is welded using a high-frequency welder, and unnecessary parts such as the opening edge f1 are removed to form a welding ridge t and a hole for attaching the support shaft. The sun visor body s was manufactured by drilling a hole in the hole a.

(Problems to be Solved by the Invention) In the case of the sun visor body s manufactured by the above method, the welded ridge t which is welded by the welder and hardened and sharpened is formed protruding from the upper end of the sun visor body. There was a problem that the appearance of the sun visor body s deteriorated, and there was a risk that hands etc. would be injured by the welded edge t. An object of the present invention is to provide a method for manufacturing a sun visor body that eliminates the above-mentioned problems.

(Means for Solving the Problems) The present invention involves sewing together a skin material with a hole and a non-porous skin material along an endless sewing line surrounding the hole, and punching out the skin material along the sewing line. After that, the punched bag is inserted through the hole and turned over to create a skin. Next, the core is inserted into the skin through the hole, and then the hole is closed with a sealing member. The gist of this paper is a method of manufacturing a sun visor body that is closed by a sun visor body.

(Function) The present invention involves sewing together a skin material with holes and a non-porous skin material, punching it out into a predetermined shape, turning the bag inside out, sewing the entire periphery together, and hiding the seamed edges inside. In addition to creating a skinned epidermis,
With the core inserted into the skin through the hole, the hole is closed with a sealing member to seal the core into the skin, and a welding protrusion is formed from the periphery of the sun visor body in a welding process. The edges are eliminated to even out the finished state of the peripheral edge of the sun visor body.

(Example) Next, an example of the present invention will be described with reference to FIGS. 1 to 5.

Sun visor body S for light shielding installed inside the vehicle interior
When manufacturing the first skin material 1A, the first skin material 1A has a substantially frame-like shape with a square hole 2 opened substantially in the center.
and the non-porous second skin material 1B are stacked on top of each other with their skin surfaces inside, and both skin materials 1A,
1B are sewn together using an endless sewing line 3 surrounding the hole 2 in accordance with the contour shape of the sun visor body S (see FIG. 1B). As both the skin materials 1A and 1B, for example, a flexible sheet material such as cloth or leather is used.

Next, the two skin materials 1A and 1B that have been sewn together are punched out along the sewing line 3 with a cut edge slightly outside the sewing line 3 to remove unnecessary parts, and a bag with a hole 2 opened in the center of one side is formed. 4 (see Figure 1 C).
At this time, a stitched edge 9 is formed along the entire circumference between the stitched line 3 and the punched edge at the peripheral edge of the bag body 4.

Furthermore, this bag body 4 was inserted through the hole 2 and turned inside out, so that both the skin materials 1A and 1B were turned inside out, so that the hole 2 was opened in the center of one side and the sewn edge 9 was hidden inside. A skin bag 5 is created (see Figure 1 D and Figure 2).

Next, a core body 6 made of a hard synthetic resin foam and formed into approximately the same shape as the outer skin bag 5 is inserted into the hole 2.
The core body 6 is inserted into the skin bag 5 through the hole 2 while being deformed (see FIG. An exposed sun visor base 7 is created (see FIGS. 1 and 3).

Furthermore, in order to close the hole 2 in this state, a rectangular plate-shaped sealing member 8 having a size slightly larger than the hole 2 is attached to the periphery of the hole 2 and the exposed portion 6a of the core 6.
The sun visor main body S can be produced by attaching the core body 6 to the skin bag 5 with an adhesive or the like, closing the hole 2 with a sealing member 8, and sealing the core body 6 inserted into the skin bag 5 with the sealing member 8 ( (See Figures 1 and 4). However, in this example, a mirror 10 and a mirror with a lamp to which a lamp 11 is connected are attached to the peripheral edge of the hole 2 as a sealing member 8. Further, a support shaft, a support fitting, etc. are attached to the sun visor main body S as necessary.

Next, the operation and effects of the embodiment having the above configuration will be explained.

Now, in this example, the first skin material 1 with the hole 2 opened
A and a non-porous second skin material 1B are overlapped and sewn together with an endless sewing line 3 surrounding the hole 2,
Next, after punching out a part slightly outside the sewing line 3, the punched bag body 4 is turned inside out through the hole 2 to create an outer bag 5, and then the core body is passed through the hole 2 into the outer bag 5. 6 is inserted, the hole 2 is closed with a sealing member 8.

For this reason, it is possible to eliminate the conventional welding process in which the core is sealed in the skin and then weld the opening edge with a high-frequency welder, and the welded ridge formed in the welding process can be eliminated from the peripheral edge of the sun visor body. This has the effect of equalizing the finished state of the peripheral edge of the sun visor body S, improving the appearance of the sun visor body S, and eliminating the risk of injury to hands or the like by the hardened welded edge.

In particular, since the peripheral edge of the outer skin bag 5 is sewn all the way around and the sewn edge 9 formed on the outside of the sewing line 3 is hidden inside the outer skin bag 5, the finishing of the outer edge of the outer skin bag 5 is difficult. It is possible to even out the condition, hardness, softness, and feel over the entire circumference.

In addition, in order to give the sun visor body S a function different from the original function of the sun visor, a mirror,
When various members such as lamps are attached to the sun visor main body S, these various members can also be used as the sealing member 8 for closing the hole 2,
This has the effect of substantially reducing the cost for closing the hole 2.

Furthermore, since the stitched edge 9 formed on the peripheral edge of the outer skin bag 5 is hidden inside the outer skin bag 5, the control limit of punching accuracy during the punching process can be relaxed.

(Effect of the invention) That is, the present invention provides a skin material with openings,
The non-porous outer skin material is overlapped and sewn together with an endless sewing line that surrounds the hole, then punched out on the outside of this sewing line, and the punched bag is turned inside out through the hole and the outer skin is sewn. The weld process can be eliminated and the weld process can be performed by inserting the core into the skin through the hole and then closing the hole with a sealing member. By eliminating the welded edges formed during the process from the periphery of the sun visor body, it is possible to improve the appearance of the periphery of the sun visor body, and to improve the finishing condition, hardness and softness, and feel of the periphery of the skin. It has a leveling effect.

Moreover, the control limit of the punching accuracy of the bag body can be relaxed.
