DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a sun visor on a vehicle body, and more particularly to a structure for improving shock absorption.

[0002]

2. Description of the Related Art As a conventional mounting structure of a sun visor for a vehicle, for example, there is one shown in FIG. this is,
A front roof rail 21 is disposed along the vehicle width direction at the front edge of the vehicle body roof, and a side roof rail (along the front edge of the vehicle roof along the vehicle front-rear direction at the side edge of the vehicle roof). A front pillar (not shown) disposed substantially along the vertical direction of the vehicle is connected via a brace 22.

[0003] A resin headlining 23 is provided on the ceiling of the vehicle body roof, and a sun visor 24 is provided below the headlining 23.

[0004] The sun visor 24 is attached by a flat head bolt 26 with a mounting bracket 25 interposed between a head lining 23 and an embossed portion 22 a of a brace 22.

Here, the front roof rail 21 and the brace 22 are made of a steel plate.
In order to secure the bonding strength between the front roof rails and the side pillars, the brace 22 has a thickness larger than the thickness of the front roof rail 21 (for example, when the thickness of the front roof rail 21 is 0.7 mm). The thickness of the brace 22 is 1.4 mm).

[0006] As this type, Japanese Utility Model Laid-Open No. 1-14 is disclosed.
There is one described in Japanese Patent No. 5815.

[0007]

As described above, since the mounting bracket 25 is mounted on the thicker brace 22, the mounting stability of the sun visor 24 is high. In other words, the deformation of the mounting portion against external force. Resistance is high.
However, on the contrary, when an impact is applied to the sun visor 24 from the vehicle interior side due to a vehicle collision or the like, there is a problem that absorption of impact energy is not good.

Accordingly, an object of the present invention is to provide a vehicle sun visor mounting structure capable of better absorbing the shock energy when an impact load acts on the sun visor from the vehicle interior side. .

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and has a front roof rail disposed at a front edge of a vehicle body roof along a vehicle width direction; A thicker plate than the front roof rail is provided on a lower surface side of a corner where a side roof rail disposed along a vehicle front-rear direction at a side edge and a front pillar disposed substantially along the vehicle vertical direction intersect. An opening is formed in a portion of the brace overlapping the front roof rail, and the front rail
Swelling downward from the opening,
Forming an embossed portion fitted to the parts, is characterized in that fitted with service Nbaiza in the embossed portion.

[0010]

According to the present invention, since the sun visor is mounted on the front roof rail having a small thickness, the deformability of the mounting portion is higher than in the conventional case where the sun visor is mounted on the thick brace. When an impact load acts on the sun visor from the vehicle interior side, the impact energy can be favorably absorbed. In addition, since an opening is provided in the brace made of thick plate material and the sun visor is attached to the front roof rail located at this opening, the load of the sun visor itself is at the peripheral edge of the opening of the brace via the front roof rail. Because of the burden, the support strength of the sun visor can be ensured.

Further, by fitting the embossed portion of the front roof rail into the opening of the brace, the two can be positioned by the fitting at the time of assembling the vehicle body, so that the assembling workability is improved.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show one embodiment of the present invention.

First, the structure will be described. A front roof rail 1 is disposed along a vehicle width direction at a front edge portion of a vehicle body roof. And a front pillar 10 arranged substantially along the vertical direction of the vehicle via a brace 2.

The brace 2 is made of a steel plate having a thickness of 1.4 mm, and has a forked shape as shown in FIG. An opening 2a is formed in the brace 2 at a position where the sun visor 4 is attached.

The front roof rail 1 has a plate thickness of about 0.7 mm and both ends are longer than the conventional one (the right end is shown in the drawing). An embossed portion 1a fitted into the opening 2a of the brace 2 is formed downward at both ends thereof. The front roof rail 1 and the brace 2 are connected to the embossed portion 1a.
Is inserted into the opening 2a of the brace 2, and the opening 2
Spot welding is performed at several locations on the periphery of a.
In addition, the welding location of this spot welding is sufficient as the bonding strength between the front roof rail 1 and the brace 2,
In addition, it is determined that the embossed portion 1a is deformed at the time of impact and can absorb impact energy.

The front roof rail 1 and the brace 2
A resin headlining 3 forming a vehicle body ceiling is disposed below the headliner. The head lining 3 is formed with a convex portion 3a at the same position as the embossed portion 1a, whereby the front roof rail 1 and the head lining 3 are formed.
And a gap is secured between them.

In the convex portion 3a and the bottom surface of the embossed portion 1a of the front roof rail 1, there are several holes 3b, 1
b are formed, and the mounting bracket 5 of the sun visor 4 is mounted by the countersunk bolts 6 and the nuts 11 through the holes 3b and 1b. The sun visor 4 is mounted via the mounting bracket 5.

More specifically, the sun visor 4 has a sunshade portion 8 rotatably provided on a horizontal axis 7a of an L-shaped support shaft 7, and a vertical axis 7b of the support shaft 7 rotatably mounted on the mounting bracket 5. Is provided. The support shaft (not shown) is detachably supported by the mounting bracket 5. Then, as shown in FIG.
And by rotating the sunshade surface portion 8 about the longitudinal axis 7b of the support shaft 7, it can be used as a sunshade for the side of the vehicle. The mounting bracket 5
Since the mounting position is the same as the conventional one, even when used as a sunshade for the side of the vehicle, the sunshade surface portion 8 is located at the same position as the conventional one, and can exhibit the same sunshade function as the conventional one.

According to the mounting structure of the sun visor 4 having such a configuration, the mounting bracket 5 of the sun visor 4 is mounted on the front roof rail 1 having a small thickness. As compared with the case where the sun visor 4 is mounted, the deformability of the mounting portion is higher, and when an impact load acts on the sun visor 4 from the vehicle interior side, the impact energy can be favorably absorbed. Further, since the opening 2a is provided in the brace 2 made of a thick plate, and the sun visor 4 is attached to the front roof rail 1 located at the opening 2a, the load of the sun visor 4 itself is reduced by the brace via the front roof rail 1. 2 opening 2
Since it is borne by the peripheral portion of a, the supporting strength of the sun visor 4 can be ensured.

Further, an embossed portion 1a swelling downward is formed at the edge of the front roof rail 1, and the embossed portion 1a is fitted into the opening 2a of the brace 2, so that the fitting is achieved by the fitting during the assembly of the vehicle body. Both can be positioned, and assembling workability is improved.

[0022]

As described above, according to the present invention, since the sun visor is mounted on the front roof rail having a small thickness, the sun visor is compared with a conventional case where the sun visor is mounted on a thick brace. When the mounting portion has a high deformability and an impact load acts on the sun visor from the vehicle interior side, the impact energy can be favorably absorbed. In addition, since an opening is provided in the brace made of thick plate material and the sun visor is attached to the front roof rail located at this opening, the load of the sun visor itself is at the periphery of the opening of the brace via the front roof rail. Because of the burden, the support strength of the sun visor can be ensured.

Further, by fitting the embossed portion of the front roof rail into the opening of the brace, the two can be positioned by the fitting at the time of assembling the vehicle body, so that the assembling workability is improved.
