[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunroof shade device.

[0002]

2. Description of the Related Art Conventionally, as a sunroof shade device, for example, a sunroof shade device described in Japanese Utility Model Application Laid-Open No. 63-4828 (this is referred to as a first prior art) and Japanese Utility Model Application Laid-Open No. 3-12491.
Japanese Unexamined Patent Publication No. 3 (this is referred to as a second prior art) is known.

[0003] In the first prior art, a hatch made of a transparent material is provided in an opening formed in a roof, and a shade covering the interior side of the hatch is formed of a rollable material, and a front edge of the opening is formed. A retractor configured to be able to take up and pull out a shade is provided inside the roof of the vehicle, and a hook that can engage a handle provided at a tip of the shade is provided at a rear edge of the opening. I have. That is, when the shade is pulled out from the retractor and the handle is engaged with the hook, the cabin side of the hatch is shielded by the shade, and when the shade is wound around the retractor, the hatch is not shielded by the shade. .

In the second prior art, a hatch made of a transparent material is provided in an opening formed in a roof, and a shade plate covering the inside of the hatch inside the cabin inside the cabin inside the hatch vertically overlaps the hatch. And the hatch is slidably supported at the open position stored inside the roof without overlapping vertically. That is, when the shade plate is slid to the closed position, the hatch is shielded by the shade, and when the shade is slid to the open position, the shade is stored in the roof and the hatch is not shielded.

[0005]

However, in the first prior art, since the shade is wound up by the retractor, the front and rear space for storing the shade on the roof is small, and the opening of the opening is small. Although a large area can be ensured, there is a problem that a vertical dimension for accommodating the retractor inside the roof is required, and the thickness of the roof at this portion is increased, and the head clearance is reduced.

On the other hand, the second prior art has a structure in which the shade plate is slid, so that the vertical dimension required for storing the shade plate is small, and it is easy to secure the head clearance by making the roof thinner. However, there is a problem that the front and rear dimensions for storing the shade plate in the roof other than the opening are required, so that a large area of the opening cannot be secured.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems.
The purpose is to achieve both head clearance and head clearance.

[0008]

In order to achieve the above-mentioned object, a sheet-shaped shade is provided in a roof of a vehicle body, the opening being closed by a hatch made of a transparent material, and the hatch of the hatch is closed. Is provided, at the front edge or the rear edge of the opening of the roof, while storing a shade, is provided with a shade storage section in which a shade doorway for entering and exiting the shade at the end on the opening side is provided,
One or a plurality of fixed rods which are horizontally mounted in the shade storage portion in the vehicle width direction and fixed at end positions on the shade entrance / exit side, and which are horizontally mounted in the shade storage portion in the vehicle width direction. And a guide means extending in the front-rear direction to the shade storage portion is provided with one or a plurality of slide rods slidably supported at both left and right end portions back and forth, and is inserted into the shade storage portion from the shade doorway. A folding mechanism is provided that folds the shade with a slide rod, folds the fixed rod with a fixed rod, and folds the shade with a folding line that extends in the vehicle width direction. A drive means for moving from the position to the end position on the opposite side is provided.

According to the second aspect of the present invention, the driving means is constituted by a spring which urges each slide rod in a direction away from the shade entrance and exit, and stores the shade with one end of the shade and an opening of the roof. A lock mechanism is provided at the end opposite to the side where the part is provided.

According to the third aspect of the present invention, the driving means comprises a spring for urging each slide rod in a direction away from the shade port and an actuator for pulling the shade in the opening closing direction.

[0011]

In the shade device according to the first aspect, when the shade is opened without blocking the hatch, the shade is folded in a zigzag manner by being folded back by the slide rod or the slide rod and the fixed rod of the folding mechanism in the shade storage portion. I have.

Next, when the shade for closing the hatch is closed, one end of the shade is pulled toward the opening from the shade entrance / exit of the shade storage portion, and the pulling force pulls the slide rod in the direction of the shade entrance / exit and the guide means. The shade is drawn out from the shade doorway by an amount that moves along the fixed rod and reduces the turnover between the shade rod and the fixed rod.
In this case, since the shade is folded back by the slide rod, the shade having a length approximately twice as long as the movement amount of one slide rod is drawn out from the shade entrance / exit.

Next, when the shade is opened again, the slide rod is slid by the driving means in a direction away from the shade doorway. As a result, the amount of turning back of the shade between the fixed rod and the slide rod increases, and the shade is drawn into the shade storage portion, so that the hatch is not shielded.

In the apparatus according to the second aspect, when the shade is closed, the slide rod is pulled out while resisting the urging force of the spring for urging the slide rod. Therefore, when the shade is opened, the slide rod slides due to the urging force of the spring, and the shade is drawn into the shade storage portion.

Further, when the shade is pulled out until the entire hatch is shielded, one end of the shade is fixed to the roof by the lock mechanism, and the closed state is maintained.

In the apparatus according to the third aspect, when the shade is closed, the actuator is driven in the shade withdrawing direction to draw the shade against the spring. In this case, when the drive of the actuator is stopped, the shade is tensioned inside the hatch at that position by the tension of the spring.

When the shade is opened, when the actuator is driven in the shade storage direction, the slide rod slides by the urging force of the spring, and the amount of the shade corresponding to the driving amount is stored in the shade storage portion.
