Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a sun visor for a vehicle.

[0002]

2. Description of the Related Art Conventionally, a sun visor for a vehicle has a structure in which a bearing member having a bearing hole into which a support shaft is rotatably inserted is fixed to a wire frame inside a sun visor body. It has been known. In the vehicle sun visor having such a structure, a clip for applying a required operating torque to the sun visor body is attached to a predetermined position of the bearing member. In order to prevent the sun visor body from coming off with respect to the support shaft, a protrusion for preventing the sun visor from being provided is provided on the shaft of the support shaft, while a notch-shaped engagement with the protrusion of the support shaft is provided on the bearing member. Generally, a part was formed.

[0003]

In the above-described conventional sun visor for a vehicle, a notch-shaped engaging portion which engages with a projection for retaining the support shaft is provided on a bearing member to which a clip is attached. The bearing member must be formed, and the structure of the bearing member is complicated. SUMMARY OF THE INVENTION An object of the present invention is to provide a sun visor for a vehicle in which the sun visor body can be prevented from coming off with respect to a support shaft with a simple structure in view of the above-mentioned conventional problems.

[0004]

Means for Solving the Problems To achieve the above object, the first invention has a gist as set forth in claim 1. Therefore, the retaining piece formed integrally with the clip for applying the required operating torque to the sun visor main body can prevent the sun visor main body from coming off by engaging with the retaining portion formed on the support shaft. For this reason,
With respect to the conventional bearing member, there is no need to form a notch-shaped engaging portion that engages with the protrusion for retaining the support shaft,
The structure of the bearing member is complicated. Further, it is also possible to integrally form a bearing portion having a bearing hole in the sun visor body and to eliminate the bearing member, which is highly effective in cost reduction.

Further, a second aspect of the present invention has a configuration as described in claim 2. Therefore, the clip including the tubular body through which the support shaft is inserted and elastically contractable and expandable, and the legs integrally extended from the tubular body, bends one spring plate. It can be formed by processing,
The production and assembly of the clip becomes easy.

A third aspect of the present invention has a gist of the structure according to the third aspect. Therefore, the leg portions of the clip are constituted by the first and second leg portions that are connected at one end by the folded portion, and extend integrally from the tips of the first and second leg portions, respectively. A cylindrical body of the clip is constituted by the first and second elastic pieces, which are elastically contracted / expanded with a gap set between the mutually extending ends. For this reason, a clip can be easily manufactured by bending one long spring plate.

[0007] The fourth invention has a gist of the structure as set forth in claim 4. Therefore, the first and second clips
The required elastic force can be applied to the first and second elastic pieces of the cylindrical body by restricting the two leg pieces by the restricting means. In other words, the required operating torque can be applied to the sun visor body.

[0008] The fifth invention has a gist as set forth in claim 5. Therefore, the restraining means can be constituted by the restraining piece integrally formed on the first leg piece side and the engaging portion formed on the second elastic piece side so as to be able to engage with the restraining piece. A dedicated restraining member for restraining the second leg pieces can be manufactured separately from the clip, and the labor for assembling to the clip can be reduced.

[0009] The sixth invention has a gist as set forth in claim 6. Therefore, since the bearing portion having the bearing hole into which the support shaft is relatively rotatably fitted is formed integrally with the sun visor body, a dedicated bearing member is manufactured separately from the sun visor body and assembled to the sun visor body. The labor can be reduced. Furthermore, the clip can be easily assembled from the outside of the sun visor body by forming the clip assembling hole opening outside the sun visor body so as to cross the bearing hole.

Is pressed and held. Thus, the sun visor body 20 is configured.

In this manner, the sun visor main body 20 can be easily composed mainly of the three components of the main body trim 21, the visor plate 50 and the holder 60, and the cost can be reduced. Further, the main body trim 21, the visor plate 50, and the holding body 60 are integrated by a very simple operation of press-fitting and inserting the insertion portion 63 of the holding body 60 into the annular groove 46 of the main body trim 21, and the sun visor main body 20 is integrated. Since it can be configured, it is highly effective in cost reduction. In addition, by inserting the insertion portion 63 of the holding body 60 into the annular groove 46 of the main body trim 21 by press-fitting, the engagement concave portion 64 of the insertion portion 63 and the engagement projection 47 of the annular groove 46 are engaged. In this case, the holding body 60 can be prevented from coming off by the engaging force, and a problem that the holding body 60 comes out unexpectedly can be prevented.

In the sun visor main body 20 configured as described above, a clip 70 is inserted and mounted in the clip mounting hole 24 of the main body trim 21.
Then, the bearing hole 23 of the bearing part 22 of the main body trim 21 is formed.
When the horizontal shaft 14 of the support shaft 10 is inserted into the clip 70, the horizontal shaft 14 is pushed in while elastically expanding the insertion hole of the cylindrical body 75 of the clip 70. As shown in FIG.
Is inserted to a predetermined position of the bearing hole 23 of the bearing portion 22 of the main body trim 21 so that the horizontal shaft portion 14
The claw portion 87 of the retaining piece 86 of the clip 70 is engaged with the retaining groove 16 of FIG. Then, the sun visor body 20 is prevented from coming off the horizontal shaft portion 14 of the support shaft 10 by the engaging force of the retaining piece 86 of the clip 70 with the retaining groove 16 of the horizontal shaft portion 14.

By integrally molding the bearing portion 22 having the bearing hole 23 with the main body trim 21, it is necessary to form a dedicated bearing member and dispose the bearing member inside the sun visor body, unlike the related art. As a result, the number of parts and the number of assembling steps can be reduced correspondingly, and the cost can be reduced. Further, the sun visor body 20 can be prevented from coming off by a simple structure in which the retaining piece 86 formed on the clip 70 is engaged with the retaining groove 16 of the horizontal shaft portion 14.

As described above, the sun visor body 20 is mounted on the horizontal shaft portion 14 of the support shaft 10 to constitute the sun visor 1 for a vehicle. A bracket 2 is attached to the longitudinal axis portion 11 of the support shaft 10, and the support shaft 1 is attached by the bracket 2.
With 0, the sun visor body 20 is mounted on the front side of the ceiling of the vehicle compartment. The sun visor body 20 (body trim 2)
The first to third engaging portions 31 and 3 of the support shaft 30 of 1)
One of the hooks 2 and 33 is selected and hooked to a fixed support hook (not shown) at the front side of the ceiling of the passenger compartment so as to be detachable. Thereby, the sun visor body 20
Is stably supported. In other words, in a vehicle having a different cabin width, the distance from the position where the support shaft 10 is mounted to the support hook may be large or small. Even in such a case, the first to third of the support shaft 30 may be different. It is possible to select one of the hooking portions 31, 32, and 33 and to hook it on the support hook.

As described above, when the vehicle sun visor 1 is mounted, the sun visor main body 20 is rotated around the axis of the horizontal shaft portion 14 of the support shaft 10, so that the sun visor main body 20 is attached to the vehicle ceiling surface. The arrangement is switched between a storage position along the windshield position and a light shielding position along the windshield. When the sun visor body 20 is in the storage position, the engagement surface 15 of the horizontal shaft portion 14 and the engagement pieces 80 and 81 of the clip 70 are engaged with each other as shown in FIGS. Thus, the sun visor body 20 is held at the storage position.

When the sun visor body 20 is rotated against the engaging force between the engaging surface 15 of the horizontal shaft portion 14 of the support shaft 10 and the engaging pieces 80 and 81 of the clip 70, the sun visor body 20 is rotated. 20 rotates toward the light blocking position. At this time, the cylindrical body 75 of the clip 70 is elastically expanded while being in contact with the outer peripheral surface of the horizontal shaft portion 14. Then, the sun visor main body 20 is rotated by a required operation torque exceeding the rotational friction force generated between the inner peripheral surface of the cylindrical body 75 and the outer peripheral surface of the horizontal shaft portion 14, so that the sun visor main body 20 is in a desired state. It is arranged at a light shielding position. Immediately before the sun visor body 20 arranged at the light blocking position is arranged at the original storage position, the sun visor body 20 is moved to the storage position under the action of the elastic force based on the elastic expansion of the tubular body 75 of the clip 70. Is rotated until.

In the clip 70 of this embodiment, as shown in FIGS. 7 and 8, the restraining piece 82 of the first leg 73 is engaged with the engaging hole 83 of the second leg 74. By doing so, the first leg piece 73 and the second leg piece 74 can be restrained in a closed state. Then, a required elastic force can be applied to the cylindrical body 75 constituted by the first elastic piece 77 and the second elastic piece 78. For this reason, the rotational friction force between the inner peripheral surface of the cylindrical body 75 and the outer peripheral surface of the horizontal shaft portion 14 is insufficient, thereby preventing the sun visor body 20 disposed at the light shielding position from unexpectedly rotating. be able to. Further, immediately before the sun visor main body 20 is placed at the original storage position, it is possible to prevent a problem that the sun visor main body 20 is not rotated to the storage position due to insufficient elasticity of the tubular body 75 of the clip 70. Furthermore, it is possible to prevent a problem that the sense of moderation when the sun visor body 20 is disposed at the storage position is lost due to the lack of elasticity of the cylindrical body 75, and the like.

In this embodiment, the first elastic piece 77 and the second elastic piece 78 constituting the cylindrical body 75 of the clip 70 are provided with an oblique gap S at the center in the width direction. A flat engagement piece 80 separated by and substantially flush with each other;
81 are formed respectively. When the sun visor body 20 is stored along the ceiling surface of the passenger compartment, the first elastic piece 77 and the second elastic piece 77
The engaging pieces 80 and 81 of the elastic piece 78 are stably engaged with each other. As a result, the sun visor body 20 can be reliably held at the storage position.

The present invention is not limited to the above embodiment. For example, in the above embodiment,
The sun visor main body 20 is constituted by the main body trim 21, the visor plate 50, and the holding body 60. However, the present invention can be implemented even if the sun visor main body has the same structure as the conventional one.

[0030]

As described above, according to the present invention,
The sun visor main body can be prevented from falling off by a very simple structure in which a retaining piece engaging with the retaining portion of the support shaft is integrally formed with a clip for applying a required operating torque to the sun visor main body.
