Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a hood type sunroof device for opening and closing a roof opening of a vehicle with a hood.

(Prior Art) Conventionally, as a hood-type sunroof, an opening is formed in a vehicle roof, and a mounting frame having an indoor opening located below the opening is fixed to the periphery of the opening of the roof. Front and rear guide rails are laid on both left and right sides of the roof, and a flexible hood that covers the roof opening and a flexible back cloth that covers the indoor opening are provided. The front ends of the hood and the back cloth serve as a front cover. While being attached, the rear end is fixed to the roof side, and the horizontal aggregate that supports the hood from the lower side and the rear aggregate of the horizontal aggregate are vertically movably connected to the horizontal aggregate and urged upward. The floating aggregate is attached to the upper surface side of the backing fabric, and the left and right sides of the front cover and the horizontal aggregate are supported by guide rails so that they can be moved back and forth. Also, fold the back cloth in a corrugated shape and extend the hood and back cloth by moving the front cover and the horizontal aggregate forward. There is something that I tried to show.

(Problems to be solved by the invention) In the above-mentioned conventional one, when high speed traveling is performed in a state where the hood is in the opening closed posture, a negative pressure is generated on the upper surface side of the hood due to the influence of the air flow, The phenomenon that the hood is pulled upward occurs. At this time, since the force that presses the floating aggregate to float is only the tension of the hood and the back cloth, there is a fear that the floating aggregate will also float as the hood floats up. And a gap is formed between the upper surface of the left and right inner openings of the mounting frame and the appearance becomes poor.

Therefore, tension members that are tensioned by the movement of the front cover when the back cloth is extended are stretched between the front cover and the rear indoor opening edge and at the left and right ends of the back cloth, and the left and right ends of the back cloth are stretched. It has been proposed that the parts be pressed against the upper surfaces of the opening edges of the left and right chambers of the mounting frame.

However, since the middle part of the back cloth in the left-right direction is not pressed, the middle part is pulled upward by the upward force acting on the floating aggregate, causing wrinkles in the back cloth, and the left and right end parts of the back cloth. It cannot be said that the seal between the upper surface of the left and right inner openings of the mounting frame is sufficiently sealed.

An object of the present invention is to provide tension to the back cloth when the opening of the hood is closed, and to make the left and right ends of the back cloth closely adhere to the left and right indoor opening edges of the mounting frame.

(Means for Solving the Problem) The technical means taken by the present invention to achieve the above-mentioned object is to install a mounting frame at the periphery of an opening of a vehicle roof, which has an indoor opening located below the opening. The front and rear guide rails are fixed on the left and right sides of the mounting frame, and a flexible hood that covers the opening and a flexible backing that covers the indoor opening are provided. While attaching to the front cover, the rear end is fixed to the roof side, and the horizontal aggregate and the floating aggregate connected to the horizontal aggregate so as to be able to float are attached below the hood and on the upper side of the back cloth. In a hood-type sunroof in which the left and right sides of the front cover and the horizontal aggregate are movably supported by guide rails in the front-rear direction, and the back cloth is foldable and extendable by the front-back movement of the front cover and the horizontal aggregate, Between the rear indoor opening edge and both left and right edges of the back cloth, A tension member is tensioned by the movement of the front cover when the cloth is extended and presses the left and right ends of the back cloth against the upper surfaces of the opening edges of the left and right chambers of the mounting frame. The tension member is attached to both ends of the tension member, and both ends of the tension member are engaged with the tension member so as to pull down the back cloth when the tension member is tensioned.

(Operation) According to the present invention, by moving the front cover 8 back and forth, the horizontal aggregate 20 moves forward and backward, and the floating aggregate 21 moves up and down, whereby the hood 7 and the back cloth 26 are folded and extended. To be done. Then, when the back cloth 26 is extended to close the indoor opening 4, the left and right ends of the back cloth 26 are pressed against the upper surfaces of the left and right indoor opening edges of the mounting frame 3 by the tension of the tension member 31. The back cloth 26 near the floating aggregate 21 is pulled down in the left-right direction via the member 29.
