[0001]

TECHNICAL FIELD The present invention relates to a sunroof device for a vehicle.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Laid-Open No. 63-215420, a sunroof panel having translucency for opening and closing a roof opening formed in a roof panel of a vehicle, and a sunroof below the roof panel. A vehicle sunroof device including a sunshade having a light-shielding property that opens and closes a vehicle compartment opening provided in a frame is known.

[0003]

In the above-mentioned conventional sunroof device, the sunshade can be opened to take in external light, and when the sunroof panel is opened, the sunshade is also automatically opened to prevent external light from being exposed. You will be able to take in the outside air, but in this state the outside light is directly incident on the passenger compartment, so when you take in the outside air, you must put up with this even if the sunshine is strong. In view of the above points, an object of the present invention is to provide a sunroof device capable of taking measures against solar radiation while taking in outside air.

[0004]

[Means for Solving the Problems] In order to solve the above problems,
In the present invention, a sunroof panel having a light-transmitting property for opening and closing a roof opening provided on a roof panel of a vehicle, and a sunshade having a light-shielding property for opening and closing a passenger compartment opening provided on a sunroof frame below the roof panel. In a sunroof device for vehicles equipped with
When released, the sunshade will be opened automatically.
The sub-sunshade having the light-reducing property and the air permeability is provided between the sunroof panel and the sunshade, and the sub-sunshade can be independently opened and closed in the open state of the sunshade.

When the sunroof panel and the sunshade are opened to take in outside air, the sun can be weakened by closing the auxiliary sunshade, and it is possible to take measures against solar radiation while taking in outside air. Also, when the sunshade is opened and only external light is taken in, the auxiliary sunshade can be closed to weaken the sunlight, which improves usability. The sub sunshade can be formed of various materials such as a blind shape. However, if the sub sunshade is formed of a mesh material, the sub sunshade functions as a screen door that prevents insects from jumping into the vehicle interior, which is advantageous.

[0006] By the way, conventionally, a rail frame formed by integrally extruding a guide rail for a sunroof panel and a guide rail for a sunshade is provided on a side portion of the sunroof frame so that the sunroof panel and the sunshade can be freely opened and closed. I support you. Then, the auxiliary sunshade is supported on the guide rail for the sunshade so as to be openable and closable via the slider attached to the side edge portion, or a guide rail is provided on the upper surface of the side edge portion of the sunshade and the auxiliary sunshade can be opened and closed on the guide rail. If the rail frame used in the conventional sunroof device is used as it is, the rail frame used in the conventional sunroof device can be used as it is, which is advantageous in reducing the cost.

1 shows the main components of a sunroof device for a vehicle. Although not shown, the vehicle sunroof device includes a sunroof frame attached to the lower side of the roof panel, and opens and closes a roof opening formed in the roof panel. The edge frame 1a has a transparent plate 1b made of glass or the like. There is provided a sunroof panel 1 formed by fitting in and a sunshade 2 formed of a light-shielding material for opening and closing a passenger compartment side opening formed in the sunroof frame.

A rail frame 3 formed by integrally extruding a guide rail 3a for the sunroof panel and a guide rail 3b for the sunshade on both the left and right sides of the sunroof frame (only one rail frame is shown in the figure). ) Is attached. A side stay 1c is fixed to a side edge portion of the sunroof panel 1, and a free slider 1d on the front side is pivotally attached to the stay 1c, and a drive slider 1e on the rear side is connected via a link 1f. Slider 1d,
1e is slidably engaged with the guide rail 3a.
When the push-pull cable 1g connected to the drive source is connected to the drive slider 1e and the drive slider 1e is pulled rearward by the cable 1g, first, the sunroof panel 1 is tilted rearward and downward via the link 1f. The sun roof panel 1 is retracted along the lower side of the roof panel so that the roof opening is opened. Although this method is called an inner slide method, it is also possible to adopt an outer slide method in which the sunroof panel is tilted rearward and upward and is retracted along the upper side of the roof panel.

The sunshade 2 is supported by a guide rail 3b so as to be movable back and forth through two front and rear sliders 2a and 2b on its side edge portion. Further, at the rear end of the sunshade 2, there is provided a convex portion 2c which can come into contact with the gutter portion 1h provided at the rear end of the sunroof panel 1 from the rear side. When the sunroof panel 1 is opened rearward, the gutter portion is provided. 1h and convex portion 2c
The sunshade 2 is pushed backward via the and to be automatically opened. In the closed state of the sunroof panel 1, the sunshade 2 can be opened and closed independently of the sunroof panel 1.

Between the sunroof panel 1 and the sunshade 2, there is provided a sub-sunshade 4 which is made of a frame member 4a and a mesh member 4b stretched between the sunroof panel 1 and the sunshade 2. The sub sunshade 4 is supported by the guide rail 3b so as to be movable back and forth via two front and rear sliders 4c and 4d attached to its side edge portion. The sliders 4c, 4
d is slidably engaged with the guide rail 3b on the front side of the respective sliders 2a and 2b of the sunshade 2, and when the sunshade 2 is open, the hand 4e provided on the front end of the sub sunshade 4 is reached. The sub sunshade 4 can be opened and closed independently of the sunshade 2.

Thus, when the sunroof panel 1 and the sunshade 2 are opened to take in the outside light and the outside air, the auxiliary sunshade 4 can be closed to take in the outside air and weaken the sunshine. It is possible to prevent the insects from jumping in. Even when the sunshade 2 is opened and only external light is taken in with the sunroof panel 1 closed, the auxiliary sunshade 4 can be closed to reduce the sunlight.

FIG. 2 shows another embodiment in which a rear slider 2b of the sunshade 2 is engaged with a guide rail 3a for the sunroof panel by being positioned behind the drive slider 1e of the sunroof panel 1, When the sunroof panel 1 is opened, the sunshade 2 is pushed rearward through the drive slider 1e and the slider 2b to be opened. Other configurations are not particularly different from those of the above embodiment.

In both of the above embodiments, the sub sunshade 4 is used.
Is supported by the guide rail 3b for the sun shade, however, as shown in FIG. 3, the guide rail 5 may be provided on the upper surface of the side edge of the sun shade 2 and the guide sun 5 may be made to support the sub sun shade 4. . In any of the embodiments, the rail frame 3 used in the conventional sunroof device that does not include the sub sunshade 4 can be used as it is, and the cost can be reduced.
