Description

  The present invention relates to an on-vehicle sun visor that can be connected to a light shielding plate provided in the interior of an automobile and can block light incident from the outside into the interior of the vehicle more preferably.

  For the driver driving a car, the reduction or increase in the amount of light incident on the view more than necessary is a major factor that hinders safe and comfortable driving. In particular, due to the position of the sun during the daytime, sunlight is directly incident in the car, which often causes the driver's visibility to be extremely deteriorated. In addition, since the direction in which the vehicle travels during travel changes with time, it is necessary to continuously take measures to secure visibility from sunlight according to the incident direction and angle. For this reason, the driver blocks the light by using a light shielding plate provided in advance in the car to secure a field of view.

  Further, when the light shielding plate alone can not sufficiently block the light, an additional on-vehicle sun visor may be used which is attached to the light shielding plate and used. The sun visor changes the angle of the sun visor surface in the front-rear direction with respect to the driver's line of sight, with a pivoting part provided on the mounting clip for gripping the light shielding plate, and the sun visor surface and the light shielding plate By adjusting the swing angle in accordance with the incident direction of sunlight or the like and the light source position, the range in which light is blocked by the sun visor in the driver's field of view is determined (see, for example, Patent Document 1).

  Furthermore, a part that slidably holds the sun visor in the left-right direction is connected below the fulcrum of the rotation portion of the mounting clip, and the sun visor is slid in the left-right direction to further shield the driver's desire There is one that can be placed in position (see, for example, Patent Document 2).

  However, most conventional sun visors cope with light shielding only by the movable function of the screen, and are flexible and simple with respect to the incident angle of light, the direction, and the position of the light source, which adversely affect the driver's view. It was not possible to shade accordingly.

  Therefore, focusing on the structure of the conventional sun visor, it is obvious that the screen that shields light has few ingenuity and the driver can not maintain a good view with a simple method, such as adjusting the position of the line of sight. There is still room for improvement.

  SUMMARY OF THE INVENTION In view of the above problems, the present invention has a sliding function and an angle adjusting function of a screen that shields light, and allows the screen to have a plurality of areas with different light shielding properties, thereby allowing the driver to perform light with a simple operation. An object of the present invention is to provide an on-vehicle sun visor capable of achieving securing of forward visibility while shielding light.

In order to solve the above problems, the present invention provides a clip unit,
Joint part,
A substantially plate-shaped screen connected to the clip portion via the joint portion and having a plurality of regions having different light blocking properties;
An upper portion of the joint portion is connected to a bottom portion of the clip portion so as to be adjustable in an anteroposterior direction.
The screen is slidably connected to the lower portion of the joint portion in the left-right direction;
To provide an on-vehicle sun visor characterized by

  In the vehicle-mounted sun visor of the present invention having such a configuration, the screen having the light shielding property can be angle-adjusted in the front-rear direction by fitting the clip portion and the joint portion. Further, since the screen and the joint portion are fitted by the slide rail disposed above the screen and the rail holding portion disposed below the joint portion, predetermined movement is possible. Position adjustment can be performed by sliding in the lateral direction between the distances (the dimension in the longitudinal direction of the slide rail).

  As described above, since the on-vehicle sun visor according to the present invention has the sliding function and the angle adjusting function, the screen can be adjusted as the light source position by arbitrarily adjusting the angle in the front and back direction and the position in the left and right direction. And can be arranged according to the incident angle.

  Furthermore, since the screen is provided with a plurality of areas with different light blocking properties, the driver can select the area of the screen and can transmit light through the areas to make a front view, so that the intensity of the incident light By using the screen and the sliding function and angle adjustment function of the screen in combination in accordance with the incident angle, it is possible to achieve the securing of the optimum view.

Further, in the above-described vehicle-mounted sun visor of the present invention,
It is desirable that the screen has an upper area different from the light shielding property and a lower area.

Further, in the above-described vehicle-mounted sun visor of the present invention,
It is desirable that embossing is performed on the entire upper region.

  Since the screen is provided with an upper area and a lower area which have different light shielding properties, the driver selects from the upper area or the lower area by changing the position (posture change) of the eye in the vertical direction. Since the light is transmitted through the front and can be visually recognized, it is possible to easily achieve both blocking of incident light and visual recognition ahead. Furthermore, since the entire upper region has been subjected to embossing, the permeability is lower than that of the lower region (the light shielding property is higher than the upper region), and even when strong light is incident, the upper region serves as the light source and the eye. The light shielding can be performed more reliably by arranging between the two.

  According to the present invention, it is possible to provide an on-vehicle sun visor capable of achieving the forward visibility while shielding the light with a simple operation.
