Description

sun visor device

technical field

The present invention relates to a sun visor device mounted on a sunroof of a vehicle.

Background technique

Generally, a vehicle sunroof in which glass is fixed to an opening provided on a vehicle roof is known. The sunroof brightens the interior of the car and gives the occupants a feeling of openness and refreshment. But on the other hand, if the sunshade device is installed for the skylight, it is possible to choose whether to block the sunlight from the skylight according to the specific conditions and requirements of the passenger. In the prior art, there is a technology related to a sun visor device mounted on the inside of a vehicle {for example, refer to Japanese Utility Model Publication No. 2-12920 [page 3 (design configuration) to page 4, line 5, FIG. 2 ]}.

The sun visor device disclosed in Japanese Utility Model Laid-Open No. 2-12920 has a pair of sun visor members divided into left and right parts. The pair of sunshield members cover the sunroof in a butted state at the central portion of the sunroof. In addition, a light-shielding portion made of ceramic print or the like is formed at the central portion of the skylight. Thereby, the gap (joint portion) between the left and right shade members is covered by the shade portion, and light can be incident therein without passing through the gap. However, like the sun visor device disclosed in Japanese Patent Application Laid-Open No. 2-12920, even if a light-shielding portion made of ceramic printing is formed on the sunroof, it cannot completely prevent light from entering through gaps in the sun visor member. In addition, there is a problem that the sunroof must be formed with a shade portion that matches the position of the pair of shade members when they are closed. The light-shielding part must be matched in position with the parts separated from it, and if the positions between them are not exactly matched, light will enter. In addition, there is another problem that forming the sunshade portion on the sunroof itself affects the feeling of openness and refreshment when the sunroof is opened.

In order to avoid the incident of light as described above, a structure in which the visor members are stacked up and down is considered, but this causes a problem of increased thickness.

FIG. 6 is an enlarged view of part VI in FIG. 3 .

As shown in FIG. 6 , on the visor members 11L and 11R, opposing holding members 12L and 12R (hereinafter referred to as 12 as needed) are provided along the inner end 11 a in the vehicle width direction. Each front end portion 12b is provided with a groove portion 14 and a protrusion portion 13 .

The holding member 12 is a component assembled from an upper member and a lower member. The holding member 12 sandwiches the inner end 11 a of the visor member 11 in the up-down direction on the base end 12 a side. In addition, on the front end portion 12b side, the upper member and the lower member are bent relative to each other to form an opening 12c that opens in the vehicle width direction. Inside the front end portion 12b, a partition wall 12d protruding downward from the upper member is formed. Furthermore, the lower surface side of the middle part 12e of the holding member 12 is recessed upwards, and it has the shape which can hook a finger|toe in this recessed part.

The protrusion 13 is made of, for example, an elastic material such as synthetic rubber, is formed in a hollow shape, and is easily deformed when an external force acts on it. The protruding portion 13 is fitted inside the front end portion 12b of the right grip member 12R, and the front end protrudes from the opening portion 12c. In addition, the groove 14 is fitted inside the front end portion 12b of the left grip member 12L, and a portion corresponding to the protruding portion 13 is formed in a concave shape. In addition, by making the partition wall 12d in close contact with the bottom of the groove portion 14 flat, even if the positional relationship between the groove portion 14 and the protrusion portion 13 deviates in the vertical direction, the distance between the groove portion 14 and the protrusion portion 13 will not change. change.

When the position of the shade members 11L and 11R in the closed state is fixed, when the protrusion 13 enters the groove 14 , a slight gap A1 is formed between the protrusion 13 and the groove 14 . The gap A1 is an interval through which light cannot enter, for example, about 3 mm. As a result, when the protruding portion 13 enters the groove portion 14 , the original incident path of light can be bent, thereby preventing light from entering through the gap between the visor members 11L, 11R. In addition, since the gap A1 is formed between the protrusion 13 and the groove 14 , even when the visor members 11L, 11R are closed with a strong force, the protrusion 13 and the groove 14 do not collide. Therefore, it is possible to prevent one visor member 11L from abutting against the corresponding visor member 11R and causing them to slide in the opening direction.

In addition, when the position of the visor members 11L, 11R is fixed in the closed state, a slight gap A2 is formed between the holding members 12L, 12R. The gap A2 is, for example, 0.5 to 2.5 cm. Furthermore, the position (joint portion) of the gap A2 and the position (joint portion) of the gap A1 are provided at positions shifted from each other in the vehicle width direction. By setting in this way, it is possible to provide double partitions on the original incident path of light.

The operation of the sun visor device 1 configured as above will be described.

If the finger is hooked in the middle part 12e of the holding member 12 shown in FIG. 6, and each visor member 11 is pulled toward the left and right directions, the visor member 11 will be guided by the guide grooves D1 and D2 (refer to FIG. 5 ). slide, thereby the glass sunroof 21 can be opened. A passenger can make any seat in the car receive sunlight from the sunroof 21 by opening any shade member 11 shown in FIG. In addition, if all the visor members 11 are opened, a large-area lighting portion can be formed, thereby effectively improving the sense of openness in the vehicle interior.

In addition, when the pair of visor members 11 are pushed toward the center in the vehicle width direction, each visor member 11 slides under the guidance of the guide grooves D1 and D2, and its position is determined by abutting against the stopper S shown in FIG. 2 . . Thereby, by closing the visor member 11, the glass sunroof is covered, and sunlight is blocked.

From the above description, the following effects can be obtained in this embodiment.

When the protruding portion 13 enters the groove portion 14, the original incident path of light can be made to meander. Therefore, it is possible to reliably prevent light from entering between the pair of visor members 11 . In addition, when the visor member 11 is closed, gaps A1, A2 are formed between the protruding portion 13 and the groove portion 14, and between the holding members 12, 12, and there is no direct contact. Therefore, it is possible to prevent one visor member 11L ( 11R) from abutting against the opposite visor member 11R ( 11L) and causing them to slide in the opening direction.

In addition, since the gap A1 and the gap A2 are shifted in the vehicle width direction, the original incident path of light is double-blocked. Therefore, it is possible to more reliably prevent light from entering between the pair of visor members 11 .

In addition, even if there is a dimensional error caused by forming or assembling the protrusion 13 and the groove 14, the protrusion 13 can easily enter the groove 14 by deformation, thereby effectively preventing light from entering. Also, even if one visor member 11L (11R) hits the opposite visor member 11R (11L), the impact can be cushioned by the deformation of the protrusion, so that each visor member 11 can be prevented from sliding in the opening direction.

In addition, since the partition wall 12d that is in close contact with the bottom of the groove portion 14 is formed as a plane, even if the positional relationship between the protrusion portion 13 and the groove portion 14 deviates, the partition wall that is in close contact with the bottom of the protrusion portion 13 and the groove portion 14 can be ensured. 12d The gap between the two remains unchanged.

The above is the description of the embodiments of the present invention. However, the present invention is not limited to the above-mentioned embodiments, and can be implemented in various forms.

For example, in the above embodiment, the sun visor device 1 is divided into three large openings 20 and arranged respectively, but one of the small openings may be arranged.

In addition, the sun visor device of the type in which the sun visor member opens in the vehicle left-right direction has been described above, but the present invention can also be applied to a sun visor device in which the sun visor member opens in the vehicle front-rear direction.
