Embodiments of the present invention will be described below with reference to the drawings. 1 is an explanatory view showing a use state of the sun visor, FIG. 2 is an explanatory view showing a stored state of the sun visor, FIG. 3 is a longitudinal sectional view showing a slide mechanism of the sun visor, and FIG. 4 is a line IV-IV in FIG. FIG. 5 is a sectional view and FIG.

As shown in the figure, a sun visor according to the present embodiment has a sun visor main body 1 formed in a substantially rectangular shape for shielding light, and the sun visor main body 1 is vertically rotated about a horizontal axis (X axis) line. And a support means 2 for supporting it rotatably about an axis (Y-axis) line. This support means 2
As shown in FIG. 3, a mounting bracket 5 is fixed to the ceiling 3 of the passenger compartment by screws 4 and an arm 6 is mounted to the mounting bracket 5.

The mounting bracket 5 is mounted on the ceiling 3 so that the shaft hole 5a is substantially horizontal in the vehicle width direction. The arm 6 is made of a rod (or pipe) having a substantially L-shape and having a circular cross section, and its horizontal shaft portion 6a is attached to the mounting bracket 5.
The shaft hole 5a is rotatably inserted into the shaft hole 5a in a state in which a predetermined slip resistance is applied and is prevented from coming off. A substantially cylindrical slider 7 fixedly incorporated in the sun visor body 1 is rotatably fitted to a vertical shaft portion 6b extending substantially orthogonally from the horizontal shaft portion 6a of the arm 6. . In the case where the sun visor body 1 is of a type formed by a foam 1a containing a frame (not shown) and a skin 1b covering the foam 1a, the slider 7 is used when the foam 1a is foamed. Visor body 1
Is insert molded at one end in the longitudinal direction.

Therefore, the sun visor main body 1 supported as described above rotates vertically with the arm 6 about the shaft hole 5a of the mounting bracket 5 to use the sun visor body 1 along the windshield 10 (FIG. 1). 1) and a stowed position along the ceiling surface (a position shown in FIG. 2).
By horizontal rotation about b, the occupant can be displaced between the front position corresponding to the windshield 10 and the lateral position of the occupant corresponding to the front door glass.

The slider 7 is slidable in the axial direction with respect to the vertical shaft 6b of the arm 6. Therefore,
When the sun visor main body 1 is displaced to the use position, the height position of the sun visor main body 1 can be adjusted.
In order to hold the sun visor body 1 after the position adjustment at the adjustment position, a leaf spring 8 as a position holding member is attached to the slider 7 side.

One end of the leaf spring 8 is fixed to the slider 7, the other end is slidable in the guide groove 7a, and has an engaging projection 8a at an intermediate portion. The engagement convex portion 8a engages with the substantially concave continuous concave portion 6c formed in the vertical axis portion 6b of the arm 6 along the axial direction, thereby holding the sun visor body 1 at the adjustment position. Therefore, the above-mentioned arm 6, slider 7 and leaf spring 8 constitute a slide mechanism of the present invention. In this case, the engagement recess 6
c is engaged with and disengaged from the engaging projection 8a.
Is elastically deformed. Therefore, the spring force of the leaf spring 8 is set so as not to hinder the sliding of the slider 7.

In order to adjust the height of the sun visor body 1 not only at the front position but also at the side position of the occupant, the engaging recess 6c is provided on the vertical shaft 6b. It is similarly provided at a position shifted by 90 degrees in the circumferential direction. In addition, the bottom surface of each engaging recess 6c is formed in a flat surface as shown in FIG. 4, and the engaging boss 8a of the leaf spring 8 abuts on this flat surface, so that the sun visor body 1 is It is positioned at the front position or the side position, respectively. In the normal state where the sun visor body 1 is displaced to the front position of the occupant, as shown in FIGS. 1 and 2, the shaft formed at the end opposite to the arm 6 is disengaged by the bearing holder 9. It is freely supported.

The sun visor for a vehicle according to the present embodiment is configured as described above. Therefore, in use, the sun visor body 1 is displaced to the use position by rotating the sun visor body 1 together with the arm 6 from the retracted position about the shaft hole 5a of the mounting bracket 5 to the use position, so that the light enters through the windshield 10. Light from the front of the vehicle can be blocked. When the light beam enters from the side through the front door glass, the sun visor body 1 is pivotally displaced to the side position of the occupant around the vertical shaft portion 6b of the arm 6 so that the light beam from the side is removed. Can be shielded from light.

When the sun visor main body 1 is detached from the bearing holder 9 in the above-described usage mode, the arm 6 is slid up and down along the vertical shaft portion 6b to manually adjust the height position. Can be adjusted. For this reason, as shown in FIG. 5, it is possible to shield the sun visor body 1 from a standard position where the sun visor body 1 is raised most (a virtual line position shown) to a lowest position (a solid line position shown) where the sun visor body 1 is most lowered. That is, according to the present embodiment, a light-shielding range corresponding to the physique of the occupant can be obtained, and the height position can be adjusted according to the incident angle (height) of the light beam. Will spread.

Further, since the sun visor body 1 can be positioned by the engagement between the engagement projection 8a of the leaf spring 8 and the engagement recess 6c of the vertical shaft 6b, the position in the vertical direction due to vehicle vibration or the like is increased. The displacement can be prevented, and the adjustment position can be reliably held. Further, the sun visor main body 1 displaced to the front position or the side position includes the engaging convex portion 8a and the engaging concave portion 6a.
Since the position is determined by the contact with the plane c, horizontal displacement due to vehicle vibration is prevented.

As described above, according to the sun visor according to the present embodiment, in addition to the function equivalent to the conventional one, the sun visor has the function of adjusting the light blocking range according to the physique of the occupant. The number of parts is smaller than that of the type that is additionally set. Also, when compared with a general standard specification sun visor, it is possible to provide a functionally superior sun visor with almost the same number of components.

It should be noted that the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist of the present invention. For example, when the sun visor body 1 is formed of a hard synthetic resin, the slider 7 is desirably formed integrally with the sun visor body 1. Further, as the position holding member that holds the sun visor body 1 at the adjustment position, for example, a ball or a pin pressed by a coil spring can be used instead of the leaf spring 8. In addition, the position holding member may be provided on the side of the vertical shaft portion 6b of the arm 6 including this case. Further, it is desirable to set a positioning mechanism between the horizontal shaft portion 6a of the arm 6 and the fitting surface of the mounting bracket 5 for securely holding the sun visor body 1 in the storage position.
