2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Laid-Open No. 55-39219, for example, guide rails installed along the left and right sides of the roof of an automobile and slidable along the guide rails. A supporting bracket (frame) of a movable roof device, which has a supported sliding panel and is configured to open and close the opening formed in the roof part by the sliding panel, is attached to the inner panel of the roof side rail. ,
It is known that a reinforcing member is arranged below the support bracket to sufficiently secure the support strength of the guide rail and to support the movable roof device in a stable state.

[0003]

When the movable roof device is configured to be stably supported by disposing the reinforcing member below the support bracket for supporting the movable roof device, as described above, By providing the reinforcing member, there are problems that the number of parts is increased and the manufacturing cost is increased, and the reinforcing member projects into the vehicle interior to reduce the vehicle interior space.

In particular, when the opening area of the opening formed in the roof portion of the vehicle body is set large, the area of the sliding panel installed in this opening becomes large, and the weight of the movable roof device becomes heavy. Inevitably, a plurality of support brackets are arranged along the sides of the opening in order to prevent the roof side rail from being deformed according to the load input from the movable roof device. By doing so, it is necessary to disperse and support the load, and there is a problem that the structure becomes more complicated.

In view of such circumstances, the present invention provides a movable roof device supporting structure for an automobile capable of stably supporting the movable roof device with a simple structure without providing a separate reinforcing member. It is a thing.

The inner panel 9 is superposed on the wall surface of the inner panel 9 located outside the vehicle and integrally joined by means such as spot welding.

The inner end of the support bracket 12 located on the rear side of the vehicle body is attached to the overlapping portion of the flange portion 26 of the pillar reinforcement 25 and the rail inner panel 9 with the attachment bolt 17. . Further, since the rail inner panel 9 and the flange portion 26 of the pillar reinforcement 25 are installed in a state of being separated from each other on the outer side of the installation position of the mounting bolt 17, the rail inner panel 9 and the flange A closed cross section 21 is formed by the portion 26.

As described above, the upper end of the pillar inner member including the pillar inner panel 14 constituting the center pillar 6 and the pillar reinforcement 25 of the quarter pillar 7 arranged behind the center inner panel 14 is attached to the left and right sides of the roof portion 1. Is introduced into the roof side rail 10 installed on the vehicle inner side and is superposed on the wall surface of the rail inner panel 9 located outside the vehicle, and the upper end portions (flange portions) 16 and 26 of the pillar inner member and the rail inner panel 9 are also provided. And the support brackets 11 and 1 of the movable roof device at the overlapping portion with
Since 2 is attached, the load input from the movable roof device is applied to the center pillar 6 and the quarter pillar 7 from the support brackets 11 and 12 via the pillar inner member.
Can be effectively supported by transmitting to the whole.

Therefore, the support brackets 11, 1 are
The movable roof device can be stably supported with a simple structure without providing a separate reinforcing member or the like for reinforcing the mounting portion of No. 2, and the vehicle interior space as in the case where the reinforcing member is provided. Can be prevented from becoming narrow. Further, even when the opening area of the opening 5 formed in the roof portion 1 is increased to increase the weight of the movable roof device, a small number of support brackets 11, 12 allows the movable roof device to be stably supported.

In particular, as shown in the above embodiment, the upper end of the pillar inner member including the pillar inner panel 14 of the center pillar 6 and the pillar reinforcement 25 of the quarter pillar 7 has a flange portion 16 extending in the front-rear direction of the vehicle body. 26, and the flange portions 16 and 26,
According to the configuration in which the rail inner panel 9 and the rail inner panel 9 are overlapped with each other, the mounting portions of the support brackets 11 and 12 can be supported over a wide range, so that the support state of the movable roof device is effectively stabilized. There is an advantage that it can be done.

Further, in the above embodiment, the center of gravity of the movable roof device according to the sliding displacement of the sliding panel 4 has a center pillar 7 disposed behind the center pillar 6 from the vicinity G1 of the installation position of the center pillar 6. The position of the center of gravity of the movable roof device is set so as to move to the vicinity G2 of the installation position of, and the support brackets 11 and 12 are arranged at positions corresponding to the installation part of the center pillar 6 and the installation part of the quarter pillar 7, respectively. Since it is provided, the movable roof device can be stably supported regardless of whether the sliding panel 4 is located at the front end position where the opening 5 is closed or at the rear end position where the opening 5 is opened. .

Further, in the above-described embodiment, the flange portions 16 and 26 provided on the upper end portion of the pillar inner member including the pillar inner panel 14 of the center pillar 6 and the pillar reinforcement 25 of the quarter pillar 7 and the rail inner panel. Closed cross section 2 formed by 9 and
Since 1 is disposed on the outer side of the installation position of the mounting bolt 17, the mounting portion of the support brackets 11 and 12 can be reinforced to effectively stabilize the supporting state of the movable roof device and the vehicle body. There is an advantage that it is possible to prevent generation of noise due to the joint portions of the flange portions 16 and 26 and the rail inner panel 9 coming into contact with each other in response to the vibration of the above.

In order to effectively improve the support strength of the movable roof device, the thickness of the pillar inner panel 14 of the center pillar 6 and the pillar reinforcement 25 of the quarter pillar 7, which are the pillar inner members, is set to the pillar outer panel. It is desirable to set it to a value larger than 13 and 23. With such a structure, the rigidity of a box-shaped vehicle body such as a so-called one-box car can be effectively improved, and the seat belt for the front seat attached to the center pillar 6 can be effectively improved. It is possible to effectively increase the support strength of the belt anchor and the like, and also effectively increase the support strength of the belt anchor of the seat belt for the rear seat and the seedback catcher of the rear seat attached to the quarter pillar 7. Can be made.

Further, in the above embodiment, an example in which the size of the opening 5 is set to a value larger than that of a normal movable roof device has been described, but the rear end position of the opening 5 is set to the installation portion of the center pillar 6. The size of the opening 5 may be set to a normal size by locating the opening 5 on the front side.
In this case, the support bracket 11 may be provided only at the position corresponding to the installation portion of the center pillar 6, and the support bracket 12 provided at the installation portion of the quarter pillar 7 may be omitted. Further, in a sedan type vehicle in which a rear pillar is arranged on the rear side of the center pillar 6, a support bracket for supporting the movable roof device may be arranged at a position corresponding to the installation portion of the rear pillar.
