Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a vehicle sun visor having a structure in which a plate-shaped core body having a skeleton body is installed in a cushion body in order to prevent deformation of the sun visor.

[0002]

2. Description of the Related Art Conventionally, a vehicle sun visor of this type of structure is manufactured as follows. First, as shown in FIG. 8, a metal wire rod is bent into a substantially annular shape corresponding to a sun visor shape to form a bone frame body 111, while a metal flat plate is folded in two to form a bearing body 115. Then, as shown in FIG. 9, both ends of the bone frame body and the bearing body 115 are fixed to each other by spot welding or the like. Further, as shown in FIG. 10, a plate-shaped core body 112 is formed by cutting a plate material such as a corrugated ball, a cardboard, and a hardboard into a shape corresponding to the inner peripheral shape of the bone frame body 111. To do. After that, as shown in FIG. 11, the plate-shaped core body 102 is fitted into the bone frame body 111, and the adhesive tape 10 is attached.
The bone frame body 111 and the plate-shaped core body 102 are connected by 9. Finally, as shown in FIGS. 6 and 7, a plate-like core body 102 having the bone frame body 111 is internally provided in a sandwich shape between the cushion bodies 104 divided into the front and back, and the cushion bodies 104 are externally mounted. By covering with the skin 105,
It was common to manufacture the vehicle sun visor 101.

[0003]

By the way, according to the above-mentioned conventional method, the bone frame body 111, the bearing body 115 and the plate-shaped core body 102 are individually formed, and then the bone frame body 111 is formed.
It is necessary to spot-weld the bearing body 115 to the frame body, fit the plate-shaped core body 102 into the bone frame body 111, and fix the plate-shaped core body 102 with the adhesive tape 109, which increases the number of parts and the number of assembling steps. It becomes high. Further, since both the frame body 111 and the bearing body 115 are made of metal, mainly iron, there is a problem that the weight becomes heavy.

In view of the above-mentioned conventional problems, an object of the present invention is to provide a method for manufacturing a vehicle sun visor which can reduce the number of parts and the number of assembling steps and can reduce the weight.

In order to achieve the above object, a method for manufacturing a vehicle sun visor according to the invention of claim 1 is for a vehicle in which a plate-shaped core body having a bone frame body is provided in a cushion body. A method for manufacturing a sun visor, wherein a plurality of connecting holes are provided in a peripheral portion of the plate-shaped core body at a position facing the bone frame body, and the plate-shaped core body is attached to the bone frame body. After being set in the corresponding molding die, a synthetic resin material is injected into the molding die, and a part of the material is filled in the plurality of connecting holes, so that the peripheral portion of the plate-shaped core body is Both front and back frame parts formed by contacting both front and back sides of
A bone frame body made of synthetic resin is integrally formed with a connecting portion that is formed in each of the plurality of connecting holes and that connects both the front and back frame portions. Further, in the method for manufacturing a vehicle sun visor according to the invention of claim 2, the bearing body is integrally formed with the bone frame body at the same time when the bone frame body is injection-molded.

[0006]

In the method for manufacturing a vehicle sun visor according to the invention of claim 1 configured as described above, a plate-shaped core is set in a molding die corresponding to the bone frame, and the bone frame is injected. By molding, at the same time, the bone frame body can be joined to the peripheral portion of the plate-shaped core body. Further, in the method for manufacturing a vehicle sun visor according to the second aspect of the present invention, the bearing body can be formed integrally with the bone frame body at the same time as the injection molding of the bone frame body.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In FIGS. 1 and 2, a vehicle sun visor 1 includes a plate-shaped core body 2 and a bone frame body 11 made of a synthetic resin, which is provided in the peripheral portion of the plate-shaped core body 2 and integrally has a bearing body 15. A cushion body 4 in which the plate-shaped core body 2 and the bone frame body 11 are provided in a sandwich state, and the cushion body 4
The outer skin 5 that covers the The support shaft 6 is rotatably fitted in the shaft hole 16 of the bearing body 15. Further, a shaft core 17 of the support shaft 7 is integrally formed at a required position of the skeleton body 11, and a flat-split cylindrical shaft 8 is attached to the shaft core 17.

As shown in FIG. 3, the plate-shaped core body 2 is formed by cutting a plate material such as a corrugated ball, a cardboard, and a hard board into a shape corresponding to a sun visor shape. A large number of connecting holes 3 are provided in the peripheral portion of the plate-shaped core body 2 at positions facing the bone frame body 11.

The bone frame body 11 is formed by injection molding of synthetic resin, and has a frame-shaped front frame portion 12 along the peripheral portion on the front surface side of the plate-like core body 2 and the plate-like core body. 2, a back frame portion 13 having a frame shape along the peripheral portion on the back surface side, and both of the front and back frame portions 12 and 1 filled in the connecting holes 3 of the plate-shaped core body 2.
It is integrally provided with the connecting portion 14 connecting the three.

That is, as shown in FIG.
After the plate-shaped core body 2 is set in the pair of molding dies 21 and 22 for injection molding corresponding to the above, a synthetic resin material is injected into the molding dies 21 and 22, and a part of the material is plate-shaped. By filling the multiple connecting holes 3 of the core body 2 respectively, both the front and back frame portions 12 and 13 forming a frame shape by contacting both the front and back surfaces of the peripheral portion of the plate-like core body 2, respectively. A bone frame body 11 made of a synthetic resin is integrally formed with a connecting portion 14 that is formed in each of the connecting holes 3 and that connects the front and back frame portions 12 and 13 together. Further, in the bone frame body 11, the bearing body 15 having the shaft hole 16 and the shaft core 17 of the support shaft 7 are made of the same material as the bone frame body 11 simultaneously with the injection molding of the bone frame body 11. They are integrally formed of resin.

On the other hand, the bone frame body 11 and the bearing body 15 are provided for the cushion body 4 in which a sheet material such as foamed resin or foamed rubber having a cushioning property such as polyurethane foam is divided into two parts. After the plate-shaped core body 2 is internally provided in a sandwiched state, the cushion body 4 is covered with the exterior skin 5, whereby the vehicle sun visor 1 is obtained.

[0012]

As described above, according to the first aspect of the present invention, the bone frame body is formed by injection molding of the synthetic resin, and at the same time, the bone frame body is joined to the peripheral portion of the plate-shaped core body. Therefore, it is possible to eliminate the trouble of assembling the plate-shaped core body and the bone frame body separately and then to assemble these both, and it is possible to reduce the cost and the bone frame body made of synthetic resin. It is possible to reduce the weight. Also,
According to the invention of claim 2, the bone frame body and the bearing body are simultaneously and integrally injection-molded, so that the number of parts and the number of assembling steps can be further reduced, and the cost and the weight can be reduced. Is big.
