Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a sunroof guide rail mounting structure, and more particularly to a sunroof guide rail mounting structure capable of increasing head clearance.

<Prior Art> A sunroof is known that has an opening provided in the roof of a vehicle and a sunroof panel that can open and close the opening, and that allows the sunroof panel to be tilted or slid. As a slide mechanism for such a sunroof, for example, stays for supporting the sunroof panel are provided at the front and rear of both side edges of the sunroof panel, and guide rails (S
There is one that has a more guided stay that allows the sunroof panel to slide.

On the other hand, glass sunroofs are sometimes used to provide a refreshing feeling due to daylight.
When driving in strong sunlight, it is a good idea to install an additional sunshade to block the direct sunlight from the glass sunroof.

By the way, when such a sunroof is installed, if there is a step between the top surface of the glass panel and the top surface of the roof when the glass panel is closed, from an aesthetic point of view, The level difference is adjusted so that the top surface and the top surface form a substantially continuous surface. The level difference is generally adjusted by adjusting the height of the glass panel, and shims are inserted between the glass panel and the stay. Therefore, for example, as disclosed in Japanese Utility Model Publication No. 58-27851, bolts are used as removable coupling screw means to connect the glass panel and the stay. The connecting portion is provided inside the indoor opening.

However, when installing a sunshade,
The problem is that the shims, stays, bolts, and covers for hiding the bolts are lowered from the glass panel, resulting in a corresponding reduction in head clearance. Furthermore, since a cover or the like is placed on the inner side of the indoor opening, the opening is pinched in the width direction, and when the sunshade is opened, there is a problem in that the substantial area of the glass portion of the glass panel is small.

<Problems to be Solved by the Invention> In view of the problems of the prior art, the main object of the present invention is to provide a sunroof guide rail mounting structure that can increase the head clearance when the sunroof is installed. Our goal is to provide the following.

Next, the nuts 26.35 are loosened, the height of the glass panel 3 is adjusted by inserting the shims 30 as described above, and then the nuts 26.35 are tightened again. Then, the glass panel 3 is returned to the fully open state, and the level difference between the top surface of the glass panel 3 and the top surface of the roof 1 is checked.

Note that the present invention is not limited to a sunroof that uses the sunshade 13 and glass panel 3 of the above embodiment, but is also applicable to a sunroof that uses a panel made of steel plate, for example. Furthermore, even if the connecting portion between the sunroof panel and the support member is provided inside the entire inner opening with respect to the guide rail 6, by using rivets or the like as the connecting means, the connecting portion can be provided on the indoor side at = 15-. Since the amount of protrusion is small, head clearance can be expanded.

Furthermore, the present invention is not limited to the sliding type sunroof shown in the above embodiment, but for example, even in a tilting type sunroof, if a sliding type link mechanism is used in the tilting mechanism part, a guide rail is provided, As in the above embodiment, the height of the rear part of the sunroof panel can be suitably adjusted by interposing the shim 51 between the frame and the guide rail, so it can also be applied to a tilt type sunroof. There are many things. In addition, with this tilt type sunroof, since the sunroof panel cannot be stored in the rear part of the roof 1 and the opening 2 cannot be fully opened, work must be done from the indoor side. It is fixed to the rail side, a blind plug is provided in the ceiling interior material, and shim adjustment work can be performed by tightening or loosening the bolt from the indoor side.

<Effects of the Invention> As described above, by interposing the shim between the guide rail and the roof side frame to adjust the level difference between the top surface of the sunroof panel and the top surface of the roof, the height difference between the sunroof panel and the sunroof panel can be adjusted. There is no need to perform shim adjustment at the joint with the support member.

Therefore, since the coupling portion can be provided outside the inner opening, not only the head clearance can be increased, but also the width direction of the indoor opening can be expanded, which has extremely large effects.
