DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deflector device for a vehicle sunroof device.

[0002]

2. Description of the Related Art An opening is provided in a part of a roof of a vehicle, a glass lid is slidably mounted in the opening, and the glass lid is slid rearward by an operation of a driving motor to open the roof. Is an open state and the glass lid is slid forward to seal the opening of the roof in a closed state, which is generally referred to as a sunroof apparatus, and is provided in more vehicles than before.

In the sunroof apparatus, left and right guide rails are disposed along lower portions on both sides of an opening provided in the roof, and a driving shoe is slidably fitted to the guide rail, and a lifting mechanism is mounted on the driving shoe. Both sides of the lid are supported via the like, and when the drive motor is driven from the fully closed state of the lid and the drive shoe slides backward through the drive cable, first, the lifting mechanism operates to lower the lid. Later slide back to full open,
When the drive shoe slides forward by the drive of the drive motor from the fully opened state, the lid slides forward, and then the elevating mechanism operates to raise the lid so that the lid is flush with the roof surface and the opening is opened. In a fully closed state.

In a sunroof device, a deflector is attached to a lower portion of a front edge of a roof opening so as to be able to undulate.
In the open state of the lid, the deflector is held in an upright use state, and the air inside the vehicle interior flows out of the roof opening due to the aerodynamic effect of the deflector, and the deflector turns downward with the lid closing operation. When the lid is fully closed, the deflector is held in a storage position substantially along the lower side of the lid.

As shown in FIG. 2, for example, the deflector has a deflector plate 11 whose front edge is attached to a frame below a front edge of a roof opening by a hinge pin 11a so as to be vertically rotatable, and a sunroof is provided at a rear end. Left and right deflector arms mounted on left and right guide rails or frames of the apparatus so as to be vertically rotatable with pins 12a, and front end pins 12b slidably engaged with guide grooves 11b on side edges of the deflector plate 11. 12, a spring (not shown) for urging the deflector plate 11 to rotate upward and a spring (not shown) for urging the deflector arm 12 to rotate upward, and a lid bracket fixed to the lid of the sunroof device. A deflector shoe is provided for slidingly contacting the upper edge of the deflector arm 12, and the lid is moved forward. During the sliding closing operation, the deflector shoe slides the upper edge of the deflector arm 12 forward and presses and rotates the deflector arm 12 downward about the pin 12a, whereby the deflector plate 11 also moves the hinge pin 11a. When the lid is pivoted downward to a storage position substantially along the lower part of the lid and the lid is slid rearward, the deflector shoe slides rearward on the upper edge of the deflector arm 12 when the lid is slid rearward. Generally, the deflector plate 11 is rotated upward by the biasing force of each spring, and the deflector plate 11 is generally held at a use position standing upright at the front edge of the roof opening.

[0006]

When the lid is opened and closed,
In the sunroof device of the type that does not involve the vertical movement of the front of the lid, there is no particular problem with the deflector operating mechanism using only the deflector shoe as described above. In the case of the lid, the deflector shoe provided on the lid bracket also moves up and down integrally with the vertical movement of the front part of the lid, so when the lid is closed, it is once turned downward to the lowest position by sliding the lid forward. The deflector plate 11 and the deflector arm 12 rotate upward following the rise of the deflector shoe accompanying the raising operation of the front part of the lid, and when the lid is fully closed, as shown in FIG. The plate 11 and the deflector arm 12)
The storage position is not the lowest position shown by the chain line, but the position shown by the solid line rotated upward by a certain angle from the lowest position becomes the storage position, and the holding at the storage position becomes unstable. Not only does a certain deflector 10 flutter or hit other components, but also a gap is formed between the frame 15 and the deflector 10 where a finger or the like enters from the inside of the vehicle. If the lid is opened by mistake, the deflector 10
Has a problem that a finger or the like may be pinched by rotating downward from the storage position indicated by the solid line to the lowest position indicated by the chain line.

An object of the present invention is to solve the above-mentioned conventional problems.

[0008]

According to the present invention, a guide rail is provided along lower portions on both sides of an opening of a roof, and a driving shoe is fitted on the guide rail so as to be slidable in the front-rear direction. A lid made of glass is supported via an elevating mechanism, and a front shoe, which is a component of the elevating mechanism, is fitted to the guide rail so as to be slidable in the front-rear direction, and only the driving shoe does not slide. In a sunroof device in which the lid moves up and down by sliding in the front-rear direction and the lid operates in the front-rear direction by driving the front shoe together with the driving shoe in the front-rear direction, when the lid is slid forward, The deflector shoe slides on the upper edge and is depressed and rotated downward by pressing and rotating the deflector to the lowermost storage position. For example, the front shoe has a deflector stopper that is provided on the lid bracket and engages with the deflector arm at the lowermost position at the front end position of the lid to restrain the deflector arm from rotating upward. When the deflector shoe rises to the fully closed state and the deflector shoe moves upward from the upper edge of the deflector arm as the lid rises, the deflector stopper provided on the front shoe moves the deflector to the lowest storage position. It is possible to prevent the deflector from fluttering or hitting other parts, and to eliminate the possibility of the finger or the like being pinched.
