Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sunroof device having a sunroof on the roof of a vehicle.

A sunroof device is well known in which an opening is formed in the roof of a vehicle and the opening is opened and closed by tilting and sliding the sunroof (for example, see Japanese Patent Publication No. 46-5162).

1 and 2 show a conventional sunroof device. That is, an opening 2 is formed in the vehicle roof 1, and the cover member 3 is disposed within the opening 2. In order to open the rear part of the opening 2 by tilting the cover member 3, the cover member 3 is hinged on its front side, specifically at a point 5 which is a predetermined distance rearward from the front edge 4 but approximately on the front side. . Therefore, while the cover member 3 is being tilted, or when the cover member 3 is in the open state after chilling, the front edge 4 is below the vehicle roof 1. It is necessary to accommodate a wind reflector in the lower part of the front edge of the sunroof in order to prevent noise caused by the running wind through the opening when the opening is opened by sliding the cover member 3. Therefore, the movement of the front edge 4 of the cover member 3 below the vehicle roof 1 during and after tilting makes it difficult to accommodate the wind deflector. Furthermore, the fact that the front edge 4 of the cover member 3 is maintained at a position lower than the vehicle roof 1 after the tilting is completed means that when the vehicle is running, the wind blows from the gap 6 between the edge of the opening 2 and the front edge 4 of the cover member 3. will enter the vehicle interior,
It causes noise.

Furthermore, when sliding the cover member 3 to be stored under the roof 1 behind the opening 2, the cover member 3
If the front part of the wind deflector is lowered, it will interfere with the wind deflector, making it difficult to accommodate it (for example, see Japanese Patent Laid-Open No. 113918/1983).

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a sunroof device in which the front edge of a cover member does not move below the vehicle roof during tilting, after tilting, and during sliding.

Note that the guide plate 31 may be fixed to the front moving part 26 and the front shaft 38 may be fixed to the connecting plate 30.

Next, tilting and sliding of the cover member 11 will be explained.

When the cover member 11 is closed, the front shaft 3
8 is in the mid-height part 36 of the guide groove 34 (FIG. 3a), and the rear shaft 49 is in the lower part of the guide groove 44.

Tilting is performed by moving the cable 25 forward. As the cable 25 moves forward, the front moving section 26 and the rear moving section 27 linearly move forward along the rails 21, 22, 85. Since the front edge of the cover member 11 is in contact with the vehicle roof 12 via the lip seal 63, forward movement of the cover member 11 is prevented. The front shaft 38 is therefore guided into the lower part 35 of the guide groove 34 (FIG. 4a) and the cover member 1
1 is maintained at a constant height position, that is, the same height position as the vehicle roof 12, without descending relative to the vehicle roof 12, regardless of the turning of the cover member 11, which will be described later. , or rise. On the other hand, along with the forward movement of the rear side moving part 27,
Since the rotating plate 45 also moves forward, the rear shaft 49 comes into contact with the front end of the guide groove 44, and while the roller 90 slides on the cam surface 46 of the rotating plate 45, the rotating plate 45 is moved forward relative to the roller 47. Turn clockwise at (Figure 4b). In this way, the rear edge of the cover member 11 rises.

At the end of tilting, the front shaft 38 is in contact with the front end of the lower part 35 of the guide groove 34 (FIG. 5a), and the rotating plate 45 is almost in an upright state (FIG. 5b), so that the rear edge of the cover member 11 A predetermined vertical gap is formed between the vehicle roof 12 and the vehicle roof 12 . The height of the front edge of the cover member 11 is maintained at the same height as the vehicle roof 12, and is not lower than the vehicle roof 12.

Sliding is performed by moving the cable 25 backward. As the cable 25 moves rearward, the front moving section 26 and the rear moving section 27 linearly move rearward along the rails 21, 22, 85. When the cover member 11 is closed, the rear edge of the cover member 11 is in contact with the vehicle roof 12 (FIG. 3b), so the front shaft 38 is in contact with the high part 3 of the guide groove 34.
7, and the rear shaft 49 moves to the higher part of the guide groove 44. As a result, the cover member 11 descends while keeping its front edge and opening edge substantially opposed to each other, becomes substantially parallel to the guide rails 21, 22, and 85 (FIGS. 6a and 6b), and moves rearward.
In this way, as shown in FIG. 7, the opening 13 is completely opened.

Thus, according to the present invention, the cover member 11
to the guide plate 31 connected to the front lower part of the
A guide groove 34 is formed that extends in the front-back direction while changing in the vertical direction, and the movement of the front part of the cover member 11 during tilting and sliding is
It is defined by a guide groove 34 and a front shaft 38 inserted into the guide groove 34. In this way, during tilting and at the start of sliding, the front edge of the cover member 11 is fixed to the vehicle roof 1.
It is maintained so that it does not fall below 2. Therefore, the sunroof device of the present invention does not pose an obstacle to the arrangement of the wind deflector at the lower part of the sunroof position when the sunroof is closed, and the sunroof device of the present invention does not interfere with the arrangement of the wind deflector at the lower part of the sunroof position when the sunroof is closed. The generation of noise due to wind intrusion can be effectively prevented.

Note that FIGS. 13 to 16 show the arrangement of the wind deflector. A wind deflector 101 having a predetermined width and extending in the left-right direction is rotatably supported by a shaft 102 of a frame 16 at its front end. The hinge spring 103 is arranged at the front end of the wind deflector 101 and exerts a force in the upright direction of the wind deflector 101. Arms 104 having a predetermined length are arranged at both left and right ends of the opening 13, respectively. The arm 104 is rotatably supported by the frame 16 at the rear end, and is inserted into the elongated hole 106 of the bracket 105, which is attached to both left and right ends of the rear end of the wind deflector 101, through a pin 107 at the front end. is included. When the cover member 11 is closed (14th
) and during tilting (FIG. 15), the front shaft 38 of the front moving part 26 moves the arm 10.
4 is pressed from above, and the wind deflector 101 is maintained in a substantially horizontal state.
When the front shaft 38 moves rearward with the sliding of the cover member 11 (FIG. 13), the wind deflector 101 is moved by the hinge spring 10.
3 makes it stand up at a predetermined angle. In this way, the wind deflector 101 deflects the wind while the vehicle is sliding, thereby preventing noise caused by the wind during sliding. The sunroof device according to the invention is particularly advantageous if such a wind deflector 101 is arranged below the cover member 11 in the closed position.
