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 fourth
As shown in the figure, two pieces of skin material h are sewn together with a sewing machine so that the upper part is open, and then punched and cut on the outside of the sewn part to form a bag body f. After inserting the core body p through the opening edge f1 at the upper end, welding is performed slightly inwardly of the opening edge f1 using a high-frequency welder, and furthermore, a welding ridge t is formed, an unnecessary part is removed, and a part for attaching the support shaft is welded. The sun visor body s was manufactured by drilling a 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) A method for manufacturing a sun visor body according to the present invention involves stitching two overlapping skin materials so that a discontinuous portion is formed in a portion of the skin material in accordance with the contour shape of the sun visor body. The seamed edges are cut along the sewing lines on the outside of the sewing lines, and the opening edges are cut along the discontinuous portions. Next, this bag body is turned inside out to create an outer skin bag, and then a core body having a cut formed on one end edge is attached to the opening edge so that the cut is opposite to the opening edge. The core body is inserted into the skin bag through the core body, and then inserted near the opening edge into the cut, and this insertion part is adhered within the cut to enclose the core body in the skin bag. have

(Function) When manufacturing the sun visor body, an outer bag is created by turning over a bag body that has a seamed edge cut along the edge line and an open edge cut along the discontinuous part where there is no stitched line. By inserting the vicinity of the opening edge into the slit of the core body, which has a slit pre-formed on one end edge and inserted into the skin bag, and gluing the insertion portion within the slit, the core body is Enclose in a skin bag.

(Example) Next, an example of the present invention will be described with reference to FIGS. 1 to 3.

When manufacturing a sun visor body S having a parallel upper edge S1, a lower edge S2, a substantially straight side edge S3, and a bent side edge S4, first, two pieces of skin material 1 are cut from cloth or the like. , 1 are stacked one on top of the other with their skin surfaces facing inside, and are sewn continuously with a sewing machine in a partially discontinuous state, except for discontinuous portions 2 described later, in accordance with the contour shape of the sun visor main body S. During this sewing process, the upper edge S1, the lower edge S of the sun visor body S, the upper edge S1, and the lower edge S
2 and the bent side edge S4, respectively, to form a discontinuous portion 2 that is not sewn at a position corresponding to the straight side edge S3 of the sun visor body S (see Fig. 1). (see 4).

Next, the sewn together skin materials 1 are punched out using a press machine slightly outside the sewing line 3 and the discontinuous portion 2 to match the contour shape of the sun visor body S, and the unnecessary parts are cut to form one side edge 4a. An opened bag 4 is formed (see FIG. 1B). At this time, a stitched edge 9 is formed between the stitched line 3 and the punched edge.

Furthermore, this bag body 4 is turned over to create a bag-like outer skin bag 5 having an opening edge 5a (see FIG. (see Figure 1 D). This core body 6 is molded to fit tightly into the skin bag 5, and its width is slightly shorter than the width of the skin bag 5. A hole 7 is pre-pierced near the proximal end of the protrusion 6a of the core 6, and a linear side end surface 6b of the core 6 facing the opening edge 5a of the skin bag 5 is recessed inward. A slit-like cut 8 is provided in advance over almost the entire length.

Next, after applying adhesive to both sides of the cut 8 of the core body 6, the outer skin bag 5 near the opening edge 5a is folded inward and inserted into the cut 8 of the core body 6, and this insertion part 10 is inserted into the cut 8 of the core body 6. The core body 6 is sealed in the skin bag 5 by adhering it to the inner wall surface of the cut 8 with an adhesive (see FIG. 1E). However, the opening edge 5a of the skin bag 5 may be inserted into the cut 8, and then adhesive may be applied to the insertion portion 10 to adhere the insertion portion 10.

Furthermore, the sun visor main body S can be manufactured by punching out the support shaft hole 11 with a high-frequency welder or the like while the core body 6 is enclosed in the skin bag 5. However, the sun visor body S may be provided with a support shaft, support fittings, etc. as necessary.

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

In this example, when manufacturing the sun visor body, two overlapping skin materials 1 are sewn together along sewing lines 3 so that a discontinuous portion 2 is formed in a part to match the contour shape of the sun visor body S. , Punch out and cut both the sewn skin materials 1 and mark the sewing line 3.
A bag body 4 having a seam edge 9 cut along the sewing line 3 and an opening edge cut along the discontinuous portion 2 on the outside of the bag body 4 is formed.
After creating the outer skin bag 5 by turning over the core body 6 with a cut 8 formed on one end edge, the cut 8 forms the opening edge 5a.
The skin bag 5 is inserted through the opening edge 5a so as to face the
After inserting the core body 6 into the skin bag 5, the vicinity of the opening edge 5a is inserted into the notch 8, and this insertion portion 10 is adhered within the notch 8, thereby enclosing the core body 6 within the skin bag 5.

Therefore, when the core body 6 is enclosed in the skin bag 5, the welding process of welding a part of the peripheral edge of the skin with a high-frequency welder or the like can be eliminated, and the process of enclosing the core body 6 can be simplified.

Further, since the outer skin bag 5 is formed by turning the sewn bag body 4 inside out, the seam edge 9 formed between the sewing line 3 and the punched edge is hidden inside the outer skin bag 5, and the outer skin bag 5 The conventional welding process is used to improve the appearance of the peripheral edge of the skin bag 5 and to insert the vicinity of the opening edge 5a of the skin bag 5 into the cut 8 of the core body 6 to enclose the core body 6 inside the skin bag 5. By eliminating the hard welded edges formed by the sun visor body S from the peripheral edge of the sun visor body S, the outline shape of the sun visor body S is simplified across the sewn edges of the outer skin bag 5 and the insertion part 10, and the outline of the sun visor body S is simplified. This has the effect of improving the appearance of the peripheral area.

Further, by eliminating local differences in hardness and softness at the periphery of the sun visor body S, the hardness and softness and feel of the periphery can be made uniform over the entire circumference.

Furthermore, since the sewn edges 9 are hidden inside the outer skin bag 5, the control limit of punching accuracy in the punching process of both the outer skin materials 1 sewn together can be relaxed.

(Effects of the Invention) Since the present invention is configured as described above, it is possible to reduce the number of man-hours in the process of manufacturing the sun visor body by enclosing the core body in the skin bag, and
All of the joints between the seamed edges and the open edges of the skin bag can be enclosed within the skin bag and hidden from the outside.
The appearance and feel of the peripheral edge of the sun visor body can be improved and balanced, and since the opening edge of the skin bag is bonded within the cut, the bonding strength of the opening edge can be strengthened.
