[Object of the invention]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunroof device having a tilt function and a slide mechanism.

[0003]

2. Description of the Related Art Conventionally, a sunroof apparatus of this type is disclosed in Japanese Utility Model Laid-Open Publication No. 1-148916. This includes an opening formed in the vehicle roof,
A guide rail disposed on both side edges of the opening, a front shoe and a lyash you slidably supported by the guide rail, a support bracket rotatably supported by the front shoe, and a support bracket. A formed long hole, a link rotatably supported by the riyashiyu, a guide pin implanted in the link and slidably inserted into the long hole, and a roof panel fixed to the support bracket and opening and closing the opening. The guide pin slides in the elongated hole by sliding the riyashi you, and the support bracket is rotated by the cam action of the elongated hole by the sliding of the guide pin. , The roof panel is tilt-up, tilt-down, or slide.

[0004]

However, in the sunroof device described above, since the guide pin and the support bracket are made of metal, when the guide pin slides in the elongated hole of the support bracket, the guide pin and the elongated hole are not connected to each other. A rubbing noise is generated by sliding contact with the peripheral wall, and a vibration noise is generated by a squeeze or the like for assisting sliding of the guide pin with respect to the long hole.

[0005] Therefore, an object of the present invention is to reduce abnormal noise between a guide pin and a long hole, and to provide a technical object thereof.

Means for Solving the Problems In order to solve the above technical problem, the technical means taken in the present invention is formed so as to cover the entire peripheral wall of the elongated hole and guide pins are slidably contacted. That is , it has a resin piece.

[0008]

The above technical means operates as follows. The guide pin comes into sliding contact with the resin piece by sliding in the elongated hole of the guide pin. Thereby, rubbing noise and vibration noise can be reduced.

[0009]

An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, guide rails 2 are provided on both side edges of an opening 1 a formed in a vehicle roof 1 via a housing 3. A rain gutter portion 3a is formed at a position where the periphery of the opening 1a of the housing 3 is located. The opening 2 is provided with a roof panel 4 for opening and closing the opening 2.

As shown in FIGS. 1 and 2, support brackets 5 are fixed to both sides of the roof panel 4. The support bracket 5 has a substantially inverted L-shape having an upper wall 5a and a side wall 5b, and the support bracket 5 is fixed to the roof panel 4 at the upper wall 5a. On the guide rail 2, a front shoe 6 and a riyashiu 7 are slidably supported. A guide block 8 is fixed to the rear of the side wall 5b of the support bracket 5 at a predetermined interval. On the opposing surface of the guide block 8 and the side wall 5b, substantially inverted and substantially elliptical elongated holes 9 and 10 are formed with phases shifted in the front-rear direction. The front shoe 6 rotatably supports a front edge of a support bracket 7 by a pin 12. The lyasy you 7 is connected to a drive mechanism (not shown) via a cable 11. The link 13 is rotatably supported by the pin 7 on the reashi you 7. This link 13 has a metal guide pin 1
The guide pins 14 and 15 are slidably inserted into the elongated holes 9 and 10, respectively. A guide bar 16 is rotatably supported on the front shoe 6 by a pin 17.
When the opening 1a is closed, a rail inch channel 18 located at the rear edge of the opening 1a is connected to the guide bar 16 via a holder 19.

As shown in FIG. 3 to FIG.
The resin piece 20 that slides on the guide pin 15
Is fixed all over the area. The resin piece 20 may be formed integrally with the elongated hole 10 by indie molding or the like, or may be formed separately.

Next, the operation will be described. When the drive mechanism is actuated to slide the reashiu 7 forward through the cable 11, the guide pins 14, 15 slide in the elongated holes 9, 10, respectively. The sliding of the guide pins 14 and 15 causes the support bracket 5 to rotate about the pin 12 due to the shape (cam action) of the elongated holes 9 and 10, whereby the rear part of the roof panel 4 is lifted and tilted up. Work,
The rear part of the opening 1a is in a tilt opening state in which the rear is slightly opened. Further, when the drive mechanism is operated to slide the riyashiu 7 backward through the cable 11, the guide pins 14, 1
5 slides in the elongated holes 9 and 10, respectively. This guide pin 1
Due to the sliding of the holes 4 and 15, the brackets 5 rotate around the pins 12 in the opposite direction due to the shapes of the elongated holes 9 and 10, and the rear part of the roof panel 4 is pushed down to further tilt down and further. The guide pins 14 and 15 abut the rear ends of the slots 9 and 10 due to the sliding of the rear shell 7 rearward, and the support bracket 5 slides rearward. Thus, the opening 1a is fully opened.

As described above, the guide pin 15 slides in the elongated hole 10 due to the sliding of the re-sealing member 7. At this time, the guide pin 15 comes into sliding contact with the resin piece 20. Accordingly, it is possible to reduce the rubbing noise caused by the sliding contact when the guide pin 15 slides in the elongated hole 10 and the vibration noise due to the squeak and the like for assisting the sliding of the guide pin 15 with respect to the elongated hole 10. . In addition, by adjusting the thickness of the resin piece 20, the gap between the elongated hole 10 and the guide pin 15 can be partially adjusted, so that the strength can be improved and the play can be easily prevented.

According to the present invention, an opening formed in a vehicle roof, guide rails provided on both side edges of the opening, a front shoe and a rear shoe slidably supported by the guide rail, A support bracket rotatably supported by the front shoe, an elongated hole formed in the support bracket, a link rotatably supported by the rear shoe, and a slide implanted in the link and sliding into the elongated hole A guide pin freely inserted therethrough, and a roof panel fixed to the support bracket to open and close the opening, wherein the sliding operation of the rear shoe causes the guide pin to slide in the elongated hole, and tilt up the roof panel to rotate the said support bracket by the cam action, the sunroof device for tilt-down or sliding, the whole area of the peripheral wall of the elongated hole Since the guide pin is formed to cover the peripheral wall constituted the sunroof device with a resin piece is sliding, with the following effect can.

It is possible to reduce abnormal noises such as rubbing noise and vibration noise generated between the guide pin and the elongated hole.

By adjusting the thickness, the gap between the elongated hole and the guide pin can be partially adjusted, so that the strength can be improved and the play can be easily prevented.
