Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunroof structure in which an opening is formed in a roof panel of a vehicle, and a translucent member such as glass is attached to the opening to collect light from the opening. Sunroof structure.

[0002]

2. Description of the Related Art Conventionally, a sunroof structure is known in which an opening is formed in a roof panel of a vehicle, a translucent member such as glass is attached to the opening, and light is drawn from the opening. (For example, refer to Japanese Patent Application Laid-Open No. 10-229587) In this sunroof, an opening extending in the vehicle width direction is provided almost directly above the seating position of the occupant, and a glass panel which is a translucent member is provided in this opening. It is designed to be slidable so that lighting and ventilation can be performed. Therefore, the occupant can obtain an effect such as brightness and a feeling of openness by the sunlight and the scenery inserted from above as compared with the case without the sunroof.

However, in the prior art, since the sunshine from the sun at a high altitude, especially near noon when the sun is strong, directly enters the occupant, there is a case where the head becomes unnecessarily hot and the comfort deteriorates. As a method of preventing the direct sunlight as described above, a method of covering the opening of the sunroof with a shade or the like is conceivable, but this method has a problem in that the sunlight and the scenery are blocked and the open feeling cannot be obtained.

Further, when the sunroof structure has a relatively large opening area of the roof panel opening, the open feeling is improved, but it still has the same problem as described above.
Since it is necessary to secure the weight of the translucent member and the strength of the opening supporting it, the weight of the roof is increased and the roof is increased compared to the case where there is no sunroof or the sunroof structure in which the opening area of the roof panel opening is relatively small. There are problems that the thickness is likely to increase, the weight of the entire vehicle increases, the head clearance decreases, and the manufacturing cost increases.

Therefore, the applicant of the present invention arranged two front seats and two rear seats at both left and right ends in the vehicle width direction, and provided a substantially rectangular sunroof extending in the vehicle longitudinal direction at the center of the roof panel in the vehicle width direction. We have proposed a vehicle with a sunroof structure that is arranged from the front end to the rear end. According to the proposed sunroof structure, as compared to the above-mentioned conventional technology, the sunroof is displaced from the overhead of the occupant, and thus is less likely to receive direct sunlight,
We were able to increase the opportunities to get a sense of openness. Further, according to the structure of the sunroof proposed above, the distribution in the vehicle front-rear direction is longer than that of the above-described prior art, so that the range in which the effect of the sunroof such as a feeling of opening can be obtained in the vehicle interior can be expanded. done.

[0006]

However, even in the latter case, the shade is necessary. In general, the sunroof is configured such that one shade is stored in and around the opening so that it can be put in and taken out around the opening. Therefore, when a part of the opening is covered, the storage side is necessarily placed first. To be covered. Therefore, in the latter case where the effective range of daylighting extends over a wide range and extends in the vehicle front-rear direction, for example, when a shade is attached to the vehicle front end of the sunroof opening, the occupants in the front row open the sunroof. If the passengers in the back row request to cover, both requirements will not be satisfied, and since the shade is operated in the longitudinal direction of the opening, the operation amount of the shade is smaller than that of the former. There was a problem that it became relatively large and inconvenient.

In the latter case, the rear end portion of the translucent member attached to the opening of the sunroof in the vehicle front-rear direction is attached to a relatively low-rigidity portion of the roof panel which does not have a closed cross section. Further improvement in durability and rigidity is required.

The present invention has been made in consideration of such problems and requirements. The problem is to provide a shade having good operability in the sunroof structure extending in the vehicle front-rear direction as in the latter case. The purpose of this is to improve the usability of the sunroof and to further improve its durability and rigidity without reducing the head clearance.
