Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a method for doubly opening and closing an opening formed in the roof of an automobile using a translucent lid and a non-translucent sunshade. This article relates to a sunroof device.

(Prior art) In this type of sunroof device, it is not possible to immediately ventilate the interior of a car simply by tilting up the translucent lid, that is, by simply lifting the rear part of the lid and tilting it upward. Moreover, there is the inconvenience of having to open the sunshade.

Therefore, in conventional sunroof devices of this kind, for example, as disclosed in Japanese Utility Model Application Publication No. 132919/1983, a ventilation opening with a louver is provided in the sunshade, and the ventilation can be achieved by simply tilting up the lid. through the mouth,
Some are designed to ventilate the inside of the car, while others have a sunshade that opens slightly toward the rear when the lid is tilted up.

(Problem to be Solved by the Invention) In the above-mentioned conventional device in which the sunshade is provided with a ventilation hole, even when the lid is closed, the sunshade ventilation hole is always open, so the heating inside the car is heated through this ventilation hole. The hot air from the air conditioner and the cold air from the air conditioner may escape into the roof, causing drafts, or even if there are louvers, undesirable light from outside the car may shine into the car depending on its direction, causing the ceiling area inside the car to be exposed. It is not possible to completely block out light, and furthermore, when the sunshade is closed, the ventilation opening is always exposed to the inside of the car, which poses problems such as unfavorable aesthetics of the inside of the car.

In addition, in conventional devices in which the sunshade opens slightly rearward in conjunction with the lid's tilt amplifier, the part where the lid opens (rear) and the part where the sunshade opens (front) are shifted back and forth. However, there is a problem in that a long passage for air to flow is formed between the lid and the sunshade, resulting in poor ventilation.

The object of the present invention is to provide a sunroof system [3] that completely solves the above-mentioned problems.

(Means for Solving the Problems) The sunroof device of the present invention allows an opening formed in the roof of an automobile to be opened and closed in a double manner by having a light-transmitting lid and a non-light-transmitting sunshade. In addition, in the sunroof device, the roof is provided with a drive device that moves the lid between a fully closed position where the lid is closed and a tilted position where the lid is tilted rearward and upward from the roof. at least 2 divided into
The rear sunshade is linked to the drive device so as to open in conjunction with the movement of the lid from the fully closed position to the tilt position.

(Function) In the sunroof device of the present invention, the drive device:
When the translucent lid is chilled, the unit sunshade at the rear opens in conjunction with this, so both the lid and the sunshade open at the rear, making it possible to improve ventilation compared to conventional devices.

To close the rear unit sunshade, it may be possible to automatically close it in conjunction with the operation of the drive device when returning the lid from the tilted position to the fully closed position. After that, the rear unit sunshade may be closed manually from inside the vehicle.
