Description

  The present invention relates to a vehicle sun visor used in vehicles such as automobiles.

  In general, a sun visor used in an automobile is made of an opaque material. For this reason, when the sun visor is rotated to the use position along the windshield, the driver's front field of view is narrowed by the amount of the sun visor and the nearby traffic light becomes invisible. .

  Therefore, in the sun visor described in Patent Document 1 below, a part (lower part) of the sun visor is constituted by a net-like body. The mesh body can transmit light from the mesh. Therefore, according to this sun visor, the field of view is widened by the part constituted by the mesh, and a nearby traffic light can be seen. In addition, since the portion other than the mesh blocks light, the mesh body can reduce the amount of light incident on the eye, thereby reducing glare.

JP-A-10-181348

  However, the mesh body cannot prevent the sunlight that has passed through the mesh from being directly incident on the eyes. For this reason, in the sun visor described in Patent Document 1, the glare can be reduced to some extent, but there is also a certain limit. Therefore, there has been a demand for the development of a sun visor that can see nearby traffic lights and the like and can further reduce the glare of sunlight.

The present invention meets the above-mentioned demands. In a vehicle sun visor, at least a part of which is configured by a mesh having a mesh that allows light to pass therethrough, the translucent light-reducing member is replaced with the mesh and the light. It is characterized in that it is provided so as to face in the transmission direction.
In this case, it is desirable that the dimming member is made of a rigid plate.

  According to the present invention having the above-described characteristic configuration, the amount of light incident on the eyes by the mesh body is reduced. In addition, the light shielding plate reduces the amount of light passing through the mesh of the mesh. Therefore, it is possible to prevent the driver from feeling dazzled by sunlight that has passed through the mesh of the mesh body. Moreover, the light from the traffic light or the like can be visually observed through the mesh of the mesh body and the light reducing plate.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 and 2 show an embodiment of the present invention. The sun visor 1 of this embodiment includes a frame body 2, a mesh body 3, and a light reduction plate (light reduction member) 4.

  The frame 2 is composed of a pair of halves 2A and 2B. The half bodies 2A and 2B are formed by molding a hard resin, and have a shape obtained by dividing the frame body 2 into two at the center in the thickness direction (light transmission direction). Therefore, the pair of halves 2A and 2B are symmetric with respect to the plane that bisects them, and the thickness of the halves 2A and 2B is half the thickness of the frame 2.

  A recess 2a is formed on the inner peripheral surface of the frame 2 made up of the halves 2A and 2B. The recess 2a is arranged at the center in the thickness direction of the frame 2 so that each half of the recess 2a in the thickness direction of the frame 2 is formed in the halves 2A and 2B, respectively. And the recessed part 2a is formed over the perimeter. Clamping protrusions 2b are formed at the open side ends of both side surfaces of the recess 2a. Therefore, the width of the open end of the recess 2a is narrower by the amount of protrusion of the sandwiching protrusions 2b and 2b than the width of the bottom portion.

  The net-like body 3 is made by weaving yarns made of natural fibers, synthetic fibers or inorganic fibers, and is basically a woven fabric. The yarns constituting the mesh body 3 are woven at intervals. Therefore, the mesh of the mesh 3 can transmit light. The interval between the yarns, that is, the size of the mesh is appropriately selected according to the ratio between the amount of light blocked by the mesh 3 and the amount of light transmitted through the mesh of the mesh 3.

  The light reducing plate 4 is made of a translucent plate material. The translucent plate material may be composed of a material that is translucent in itself, or may be composed by uniformly dispersing and mixing a colorant in a transparent resin, and at least one of the transparent plate materials You may comprise by coloring a surface. In any case, the dimming plate 4 is preferably achromatic so that the light transmitted through the dimming light 4 is colorless. In this embodiment, the light reducing plate 4 is constituted by a smoked acrylic plate. The amount of light reduced by the light reducing plate 4 is appropriately determined according to the balance between the reduction of glare caused by sunlight transmitted through the mesh 3 and the visibility of signals and the like.

  The external dimensions of the light reducing plate 4 are set to be slightly larger than the inner dimensions of the frame body 2, and the mesh 3 is set to be slightly larger than the light reducing plate 4. On both sides of the light reducing plate 4, a pair of nets 3, 3 are arranged in contact with both surfaces of the light reducing plate 4. And each outer peripheral part which protruded from the light reduction board 4 of the mesh-like bodies 3 and 3 is being mutually fixed over the perimeter by means, such as sewing. Thereby, the nets 3 and 3 and the light reducing plate 4 are integrated. The integrated nets 3 and 3 and the light reducing plate 4 have their outer peripheral portions inserted into the recesses 2a and sandwiched between the sandwiching portions 2b and 2b. As a result, the frame 2, the nets 3 and 3, and the light reducing plate 4 are integrated to form the sun visor 1.

  According to the sun visor 1 having the above configuration, the light reducing plate 4 reduces the sunlight that has passed through the mesh of the mesh 3. Therefore, it is possible to prevent the driver from feeling dazzled by sunlight. In addition, since the light of the traffic light passes through the mesh of the mesh 3 and the light reducing plate 4, the driver can see the traffic light. Furthermore, since the dimming plate 4 is made of a plate material having rigidity, the strength of the sun visor 1 as a whole is improved.

  FIG. 3 shows another embodiment of the present invention. In the sun visor 1 ′ of this embodiment, only one net 3 is used. Therefore, the mesh body 3 is provided only on one surface of the light reducing plate 4. The mesh body 3 may be provided on the surface of the light reducing plate 4 facing the light incident side (the surface facing the vehicle exterior when the sun visor 1 is used) or on the opposite surface.

In addition, this invention is not limited to said embodiment, In the range which does not deviate from the summary, it can change suitably.
For example, in the above embodiment, most of the sun visor 1 except the frame body 2 is constituted by the mesh body 3 and the light reducing plate 4, but the portion located in the upper part of the inside of the frame body 2. May be constituted by an opaque plate material, and only the portion located in the lower part may be constituted by the net 3 and the light reducing plate 4.
Moreover, although it comprises the board | plate material which has rigidity as a light reduction member, you may comprise by film bodies, such as a translucent resin film.
