Abstract

PURPOSE:To improve the outside appearance and touch feeling by covering the obverse and reverse surfaces of a core body having an elastically deformable slit on the peripheral part and seaming skin members on the outer periphery of the slit and pushing the seamed part into the slit, in a sun visor for vehicle. CONSTITUTION:The obverse and reverse surfaces of a core body 1 having an elastically deformable slit 2 on the periphery are covered by two skin members 6, and the edge parts of the shin members 6 are seamed along the outer periphery of the slit 2. Therefore, a bag-shaped body 9 consisting of the skin member 6 having the core member 1 enveloped is formed. Then, a seamed part 8 is pushed into the slit 2. Therefore, the seamed part 8 can be concealed, and the outside appearance and the touch feeling of the peripheral part can be improved.

Description

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

(Prior art) In the past, Il! of the sunpipe body was used. When constructing J construction, two skin materials are sewn together along both side edges and the bottom edge to form a bag with an open top edge, and the core is inserted into the bag through the top edge of the bag. The upper end edge was welded with a high frequency welder 'C, the core was enclosed in the bag, and unnecessary parts were removed to create a sun visor body.

(Problems to be Solved by the Invention) In the case of the above-mentioned manufacturing means, there are problems that the cost is high due to the welding process and welding equipment for the bag body, and the ridge that is welded and hardened to a part of the peripheral edge of the sun visor body. As a result, there are problems in that a difference in hardness and softness occurs at the peripheral edge of the sun visor body, and the appearance of the peripheral edge deteriorates.

The present invention aims to solve the above problems.

(Means for Solving the Problems) The present invention uses two skin materials on the surface of a core body, which has a slit formed along the entire circumference at the peripheral edge, and the edges on both sides of the slit are formed to be elastically deformable. and the outer skin bag in which the peripheral edges of both skin materials are sewn together along the slits with the back surfaces stacked on top of each other to form a skin bag in which the sewn edges are formed in a circumferential shape and the core body is enclosed, The gist of the present invention is to provide a method for manufacturing a number visor main body, in which the vicinity of the sewn V edge is pushed inside the slit inside out through the slit, and is sandwiched between the edges on both sides.

(Function) The sewn edges of the inner skin, which are overlapped on the front and back sides of the core and sewn along the periphery of the core, are pushed into the slit formed on the periphery of the core, and the seamed edges are sewn on both sides of the slit. The sewn edges are held inside the core body with the sewn edges turned inside out, and the pull-out is stopped at the edges 'r4'.

(Example) Next, one embodiment of the present invention will be explained according to the inside of bacteria.

As shown in Fig. 1 (A), Fig. 2, and Fig. 3, the core 1 constituting the core of the sun visor body F1 is molded from a synthetic resin foam material, and the top of its periphery has a diameter of about 1M. A narrow slit 2 is formed over the entire circumference, and hollow portions 3.4 are formed inside the core body 1 near the periphery and near the center, respectively, and are provided on both sides of the slit 2. Each of the pair of opposing edges 5.5 has a cross section curved into a substantially arcuate shape and is elastically deformable.

In this example, the core body 1 is formed by joining a pair of shell bodies molded into the same shape so as to face each other.

W the sun visor body H! When building a JJ, first
As shown in Figure (B) and Figure 4, it is slightly larger than the core body 1,
With the two outer skins 6.6 cut into similar shapes to the core 1 stacked on the front and back surfaces of the core 1, the peripheral edge of the inner skin 6 is endlessly cut along the slit 2 of the core 1. The skin bag 9 is sewn together with a seam 7 of the shape of the shape, and a seam edge 8 is formed on the peripheral edge to form an outer skin bag 9, and the core body 1 is enclosed in the outer skin bag 9.

Next, as shown in FIG. 1(c), FIG. 5, and FIG. The seam 7 is forcibly pushed into the inside of the slit 3, and the seamed edge 8 is turned inside out to form a bulging part 10 inside the slit 2, and the seam 7 is pushed into the inside of the slit 2. The peripheral part of the skin bag 9 is fixed to the peripheral part of the core body 1 by sandwiching the vicinity of the proximal end of the swelling part 10 between both end edges 5,
A sun visor body H can be created.

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

Now, in this example, when manufacturing the sun visor body 11, two skin materials 6 are formed into a core having a slit 2 formed along the entire circumference at the periphery and edges 5 on both sides of the slit 2 being elastically deformable. The peripheral edges of both skin materials 6 are sewn together along the slits 2 while superimposed on the front and back surfaces of the body 1, so that a sewn edge 8 is formed in a circumferential shape and the core body 1 is enclosed. After configuring the outer skin bag 9, pass the area near the seamed edge 8 through the slit 2.
Push it inward in an upside-down state and pinch it between the edges 5 on both sides.

Therefore, it is possible to eliminate the welding process of welding the skin material when enclosing the core body, and to easily encapsulate the core body 1 into the skin bag 9 and finish the peripheral part of the skin bag 9. This has the effect of simplifying the manufacturing process and manufacturing equipment and reducing the manufacturing cost of the sun visor body H.

Furthermore, since the vicinity of the seamed U edge 8 of the outer skin bag 9 is inserted inside the slit 2 and the seam 7 is hidden inside the core body 1, the seamed edge 8 and the seam 7 can be removed from the peripheral edge of the sun visor body 1. By erasing it, the appearance and feel of the peripheral edge of the sun visor body H can be improved over the entire circumference, and since the bulge portion 10, which is bulged by turning over the seam edge 8, is formed inside the slit 2, the bulge can be removed. Hattori 10 is on both ends 5
The handling is properly stopped and the state in which the peripheral edge of the core body 1 is covered with the skin bag 9 can be stably maintained.

(Effects of the Invention) That is, the present invention combines two skin materials with a core body in which slits are formed around the entire circumference of the periphery, and the edges on both sides of the slits are formed to be elastically deformable. The peripheral edges of both skin materials are sewn together along the slit with the front and back surfaces stacked one on top of the other, thereby forming a skin bag in which the sewn edges are formed in a circumferential shape and the core body is enclosed. Then, the vicinity of the sewn edge is pushed inside the slit inside out through the slit and held between the edges on both sides, thereby eliminating the melting process of welding the outer skin and manufacturing the sun visor body. In addition, the manufacturing equipment can be simplified, and seams and seam edges are eliminated from the periphery of the sun visor body, thereby improving the appearance and feel of the periphery of the sun visor body over the entire circumference, thereby providing a hanging effect.
