DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunroof device for a vehicle in which a slide lid for opening and closing an opening formed in a roof of a vehicle is moved along guide rails provided on both side edges of the opening. In particular, the present invention relates to a structure of a guide and support of a drain that moves together with a slide lid.

[0002]

2. Description of the Related Art Conventional sunroof devices for vehicles include:
For example, as shown in FIG. 8, it is disposed on both side edges of an opening formed in the roof of the vehicle, and has a side wall (a1) on the opening side (right side in FIG. 8) and a side wall (left side in FIG. 8). Side wall (a2)
A slide lid (not shown) capable of opening and closing the opening is slidably supported in the front-rear direction on a guide rail (a) having a substantially U-shaped cross section, and receives and guides rainwater entering from the opening. The drain rail (b) for draining rainwater draining into a gutter groove (a3) formed integrally with the rail (a) slides in accordance with the opening and closing of the slide lid, so that the guide rail (a) is located outside the vehicle. Horizontal portion (a) formed at the upper end of the side wall (a2)
4), it was slidably mounted via the shoe (c).

[0003]

However, the above-mentioned conventional sunroof apparatus has a shoe (c) fixed to the drain (b).
Is fitted to the horizontal portion (a4) formed on the outer side wall (a2) of the guide rail (a), so that the drain (b) needs to be laid across the opening side wall (a1). is there. Therefore, the vicinity of the center of the curved drain (b) becomes higher, and both ends of the drain (b) become higher by the thickness of the shoe (c), so that the drain (b) and the slide lid are stored. There is a problem that the height dimension of the accommodation space between the roof and the ceiling must be made larger than necessary.
When the height of the opening-side wall (a1) is reduced so that the drain (b) does not interfere with the opening-side side wall (a1), the inside of the guide rail (a) and each part housed therein are reduced. However, there is a problem that the appearance is deteriorated due to being exposed to the vehicle interior side.

The present invention has been made in view of the above-described problems of the prior art, and has been made to reduce the thickness of the entire sunroof device and the height of the storage space as much as possible. It is an object of the present invention to provide a sunroof device for a vehicle that can improve the performance.

The sliding body (8a) of the rear slider (8) has a guide rail on its side on the opening (R1) side.
It is not shielded by the side wall (6a) of (6) and is not exposed to the opening (R1) side.

Next, the operation of this embodiment will be described. The operation of the tilt lid (1) is not directly related to the present invention, and therefore, the description is omitted. When the slide lid (5) is in the fully closed position shown in FIG. 3, the link (22) of the front slider (7) is connected to the control groove (6) of the guide rail (6) by the slider (23).
d) to be held in the upright position
By (6a), the sliding body (7a) and the slider (23) are shielded from being exposed to the opening (R1) side. Also, after the slider
In (8), the slider (25a) is engaged with the stopper groove (6j),
While being held in the upright position, the sliding body (8a) is shielded by the side wall (6a) and is not exposed to the opening (R1) side. The drain (12) is located below the rear end of the slide lid (5).

When the driving wire (15) is pulled by the driving means (13), the rear slider (8) moves rearward, and the slider (2) is moved.
5a) is lifted upward by the inclined portion of the guide groove (8b), comes out of the stopper groove (6j), and is guided by the guide rail.
(6) Move to the upper piece (6h). The link (2
5) is moved from the standing position to the falling position, and the slide lid (5) is in a flap down state in which the rear end is lowered.

Further, when the drive wire (15) is pulled,
The slide lid (5) moves rearward together with the front and rear sliders (7) and (8), and at a predetermined position, the slider (23) passes through the switching path (6i) and guide rail (6). By moving from the control groove (6d) to the upper piece (6e), the link (22) moves from the standing position to the lying position, and lowers the front end of the slide lid (5), as shown in FIG. Like the slide lid (5)
Slides rearward in a state where both front and rear ends are lowered, is housed in a housing space between the roof (R) and the ceiling of the vehicle, and is fully opened. The drain (12) is accommodated in the accommodation space by sliding backward on the upper piece (6e) of the guide rail (6) in accordance with the backward movement of the slide lid (5).

[0024]

(A) According to the first aspect of the present invention, the entire drain can be set as low as possible without interfering with the side wall of the guide rail, and both ends of the drain can be set at the same position. Since the guide rail can be lowered to a position close to the side wall of the outside of the vehicle, the thickness of the entire sunroof device can be reduced, and the height of the accommodation space can be reduced. In addition, the side wall on the opening side can shield each groove of the guide rail and the sliding body of the slider disposed therein so as not to be exposed to the opening side, and particularly, from the inside of the vehicle compartment. You can improve the appearance when you look at it.

(B) According to the second aspect of the present invention, the upper piece provided at the upper end of the side wall on the opening side of the guide rail can be engaged with the drain so as not to fall off, and formed below the upper piece. The space thus formed can be used as various guide means such as a control groove for guiding a slider protruding from a side surface of a link for raising and lowering a slide lid provided on a slider.

(C) According to the invention of claim 3, various guide means can be incorporated in the side wall on the opening side of the guide rail which is higher than the other side wall.
