Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention (Industrial Application Field) This invention relates to a hood member tensioning device for a hood type sunroof device.

(Prior Art) Generally, the hood member of a hood type sunroof device is made of a flexible material and is folded to one side of the roof opening when the sunroof is fully opened.

The canopy member is provided with a front cover and a catcher cover at the front and rear, and since the middle part is foldable, it is difficult to ensure watertightness in the middle part, which has no rigidity, when it is fully opened. For this purpose, for example, a system is known that uses tension members to maintain tension on both sides when the top member is fully opened, as described in Japanese Utility Model Application Publication No. 63-15222.

The tension member 103 is formed of Y-V- or the like, and as shown in FIGS. 6 and 7, tension members 103 are provided on both sides of the hood member 101, and the tension member 103 is given tension by a spring member 105. . The spring member 105 is a hollow cylindrical portion 10
It has a structure in which it is inserted and protected within 7.

(Problem to be Solved by the Invention) As described above, the spring member 105 that applies tension is inserted into the hollow cylindrical portion 107, and then
In the region J5, both sides of the hood member 101 appear to have a large thickness D.

For this reason, it is particularly strongly affected by wind pressure from the side, and in some cases, there is a risk that it may be pushed up and rainwater may enter the vehicle interior. In recent years, due to the development of expressways, there are many regular meetings that run at high speeds, and the current situation is that the body itself is designed to be a Flash Surf Ace in order to reduce wind resistance as much as possible. This goes against the trend of becoming an ace, and what's more, the surfacing phenomenon becomes stronger. In addition, if the depth D is large, it is likely to be affected by rainwater such as direct rain, which is undesirable from the standpoint of sealing performance. In addition, since the tension member 103 passing through the cylindrical portion 107 moves inward from the folded portion in the intermediate region of the hood member 101, the hood member 1
01, it was difficult to obtain tension toward the inside of the car, making it easy to float.

Therefore, with this invention, it is possible to obtain the tension of the top member in the direction of the inside of the car with a simple device, and it is also watertight and has a floating V property. It is an object of the present invention to provide a hood member tensioning device for a hood type Sunroots device.

[Structure of the Invention (Means for Solving the Problem) In order to achieve the above object, the present invention includes a front bracket and a seat bracket that cover the roof opening of the vehicle body, and when the roof opening is fully opened, the roof opening is closed. In the J-shaped hood type ZANRU 7 device in which a canopy member that can be opened and closed by folding on one side is installed, a tension body is passed through the bag-shaped folded portions formed on both sides of the canopy member, and in the area of the front bracket,
One end of the tension body, which is pushed against the inner wall surface of the folded part by the guide part and guided inward, is locked to the locking member, while the inner wall surface of the folded part is pressed by the guide part in the region of the rear bracket. A biasing means H2 is provided for locking the other end of the tensioning body, which is pressed against and guided inward, to a locking member, and at least one of the locking members applies a tensioning force to the tensioning body. .

(Function) According to such a hood member tensioning device, when the hood member is fully opened, g-tension can be obtained by the tensioning bodies on both sides of the hood member. At this time of tension, since the locking member is located inward, it does not affect the thickness of the folded portion.

Further, since the tension member is pressed against the inner wall surface of the folded portion by the guide portion, the hood member is given tension in the direction of the interior of the vehicle and is strongly pressed downward.

In this case, since the thickness of the folded portion is reduced to the thickness of the guide portion, the influence of rain and scum from the sides can be reduced.

(Embodiment) Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings of FIGS. 7 to 5.

In the figure, reference numeral 1 indicates a roof opening provided on the roof of the vehicle body. A top frame is provided. Flange portion 3a of guide rail member 3.3
