As shown in the figure, since the seat rail is built into the roof side 1, the roof side 1 is formed in a considerably bulging shape on the inside of the vehicle.

By the way, the sun visor 2 is usually located on both sides of the upper part of the front window to block direct eye light, but in the case of a car equipped with the above-mentioned passive seat belt, when the sun visor 2 is stored on the ceiling surface, Bulging end 1a of roof side 1
(shown by the shaded area in Fig. 6) and the sun visor 2, and not only can a smooth retracting operation not be expected, but
There was a problem that it could not be held in the correct storage position.

As a countermeasure for these, in order to avoid the bulging end 1a of the roof side 1, the side edge 3a of the sun visor body 3 is
A sun visor molded into a curved shape has been proposed, but not only is the molding cost high, but it also does not look good when in use, so improvements have been desired.

In this regard, the side edge 3a of the sun visor body 3
A sun visor of a type that prevents interference with the roof side 1 is being considered by cutting out the roof side 1, that is, setting the longitudinal dimension to be small (reducing the side edge 1 to 3b shown by a dashed line).

However, in the case of such a miniaturized sun visor 2, when the sun visor 2 is used, a gap is created between the side edge 3b of the sun visor body 3 and the front pillar 4, and sufficient light shielding performance cannot be obtained. Driving was not always satisfactory.

《Purpose of the invention》 This invention was made in view of the above-mentioned circumstances, and the purpose of the invention is to provide a sun visor for use in a vehicle with passive seat belts, to ensure the desired light-shielding performance, and to To provide a sun visor for an automobile that can be expected to be smoothly retracted without interfering with the vehicle body side (roof side) when the sun visor is retracted.

<<Configuration and Effects of the Invention>> In order to achieve the above object, a sun visor according to the present invention includes a sun visor main body having an opening at one side edge and a recess formed from the opening toward the center, and the sun visor body. An auxiliary visor is housed in a recess of the main body so as to be freely drawn out, a biasing means for pulling the auxiliary visor into the recess, and when the sun visor is used, the auxiliary visor is pulled out to the side relative to the biasing means and placed in a predetermined position. and an engaging means for positioning and engaging the auxiliary visor with respect to the sun visor main body, and when the sun visor main body is stored on the ceiling surface, the auxiliary visor pulled out from the sun visor main body comes into contact with and is pressed against the vehicle body side, and the above-mentioned engagement means is provided. The auxiliary visor is characterized in that the auxiliary visor is automatically housed in the recess in the sun visor body when the coupling means is released.

That is, according to the present invention, the auxiliary visor is housed within the sun visor main body, and this auxiliary visor can be freely pulled out from one side edge of the main body, so when using the sun visor, by pulling out the auxiliary visor, sufficient light shielding can be achieved. This increases the area and greatly contributes to safe driving.

Furthermore, in the present application, when the auxiliary visor is pulled out and the sun visor in use is stored on the ceiling surface, the auxiliary visor comes into contact with the vehicle body side (the roof side that protrudes toward the interior of the vehicle) and is pressed. Since this auxiliary visor is automatically stored in the sun visor main body, there is an advantage that it can be easily and smoothly retracted without interfering with the roof side.

<<Description of Embodiment>> Hereinafter, an embodiment of the automobile sun visor according to the present invention will be described in detail with reference to the accompanying drawings.
