Description

  The present invention relates to a deflector device for a vehicle sunroof.

In a general vehicle sunroof, the lid is slidably disposed in the front-rear direction of the vehicle body in the opening formed in the roof panel. When the lid is in the rear storage position, the opening is opened and the lid is moved forward. The opening closes when overhanging.
In addition, a deflector device having a rectifying action is installed in front of the opening. The deflector device includes a deflector arm that can be raised and lowered on both sides of an opening, and a deflector blade installed between the front end portions of the left and right deflector arms. When the lid is retracted, the deflector arm and the deflector are spring-powered. When the blade stands up and the lid moves forward, the deflector arm and the deflector blade are pushed from above and fall down.

As a mechanism for raising the deflector panel consisting of the deflector arm and the deflector blade, one end is locked to the front side of the housing fixed to the vehicle opening, and the other end is locked to the deflector panel. There is known a sliding roof device for a vehicle provided with a coil spring that urges a deflector panel in a standing state (see Patent Document 1).
However, this requires troublesome assembly because the deflector panel must be attached to the vehicle roof and the coil spring must be attached to the housing. Further, since the coil spring has a height even in a compressed state, it is difficult to increase the standing angle of the deflector panel, and in order to lower the mounting position of the coil spring, the shape of the housing must be changed.

Also, a leaf spring having one end pivotally attached to the inner frame side so as to be able to stand up / fall down and a rectifying plate connected to the other end, and one end fixed to the inner frame side to urge the arm to the standing state A deflector of a sunroof device having a radiant angle is also known (see Patent Document 2).
This deflector device has a drawback in that a link mechanism for determining the standing angle of the arm has to be installed separately, so that the number of parts increases, installation is troublesome, and cost increases.

A groove 16 that is slightly wider than the leaf spring 5 is formed on the outer periphery of the slide pin 15 along the circumferential direction, and the front end of the leaf spring 5 is wound around the groove 16.
The slide pin 15 is slidably engaged with the inside of the guide member 6 in the front-rear direction, and the front end portion of the leaf spring 5 wound around the slide pin 15 is inserted into the guide groove 7 formed in the bottom portion of the guide member 6 in the front-rear direction. Is slidably engaged.

When the lid c moves forward and the opening b is closed, as shown by a broken line in FIG. 3, the deflector arm 3 is laid down by being pressed by the lid c from above. Then, the leaf spring 5 installed below the deflector arm 3 is also pressed flat, and the front end portion of the leaf spring 5 is positioned closer to the front end of the guide groove 7 of the guide member 6 as indicated by the broken line in FIG.
When the lid c is retracted and the opening b is opened, the force for pressing from the upper side disappears. Therefore, as shown by the solid line in FIG. 2, the deflector arm 3 is moved upward by the force that the leaf spring 5 tries to return to the normal state. Pushed up. As a result, the deflector blade 4 that is installed at the front end of the deflector arm 3 and has a rectifying action projects upward from the opening b.

Along with this, the front end of the leaf spring 5 retreats along the guide groove 7 of the guide member 6, and the slide pin 15 attached to the front end of the leaf spring 5 also moves backward in the guide member 6. To do.
Then, the slide pin 15 comes into contact with the front end surface of the spacer 8, and further retreat is restricted, and the standing angle of the deflector arm 3 is determined.
At this time, the front end portion of the leaf spring 5 wound around the slide pin 15 enters the notch 10 of the spacer 8.

Therefore, by changing the dimension of the spacer 8 in the front-rear direction, the rear stop position of the front end portion of the leaf spring 5 is changed, whereby the standing angle of the deflector arm 3 can be changed.
Further, since the leaf spring 5 is caught above the receiving shaft 14 to restrict the rise of the deflector arm 3, the deflector arm 3 and the deflector blade 4 provided at the front end thereof are less likely to be rattled. Even if the shaft support portion for the deflector bracket 2 is damaged, the deflector arm 3 and the deflector blade 4 do not fall off.
