Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a roof opening / closing device for a convertible vehicle.

[0002]

2. Description of the Related Art As a conventional apparatus of this type, Japanese Patent Laid-Open No. 8-2
44465. In this device, the roof link mechanism that supports the roof and the luggage link mechanism that supports the luggage hood each have a drive unit that operates independently to fold the roof of the convertible car and open the cabin to the outside. Are stored in the trunk.

[0003]

However, since the roof link mechanism and the luggage link mechanism operate independently of each other, each mechanism needs to have a high rigidity. Therefore, the mechanism itself becomes large in size, and the weight accordingly. The production cost has increased and the manufacturing cost has increased. In addition, the volume occupied by the luggage link mechanism in the trunk becomes large, and the luggage compartment space in the trunk becomes narrow.

Since the roof link mechanism and the luggage link mechanism are separate mechanisms even when the trunk lid is opened, the roof supported by the roof link mechanism remains in the retracted position. For this reason, the frontage of the trunk, which consists of the stored roof panel and the opening edge of the trunk, becomes narrower,
It was difficult to put luggage in and out of the trunk.

SUMMARY OF THE INVENTION An object of the present invention is to provide a roof opening / closing device in which a mechanism for moving a roof and a trunk lid of a convertible vehicle is downsized and a front opening of the trunk can be widened even when the roof is stored in the trunk. That is.

[0006]

The first technical means taken in order to solve the above-mentioned technical problem is, as shown in the characteristic item 1, "a roof panel mounted above the vehicle cabin, In the vehicle, a back window that is rotatably connected to the rear side of the roof panel, a roof panel that is moved rearward of the vehicle to overlap the back window, and a trunk that is disposed behind the vehicle. A roof link mechanism that moves the roof panel and the back window inward, a luggage link mechanism that supports a trunk lid that covers a trunk so that the trunk lid can be opened and closed at at least one of the front and the rear of the vehicle body, the back window, the trunk lid, and the Roof opening and closing, characterized by including a connecting means for connecting any one of the luggage link mechanisms. It is that you have configured the location. "

According to the above construction, when the roof panel of the vehicle is stored in the trunk and the passenger compartment is opened to the outside air, the roof panel and the back window are overlapped by the roof link mechanism and moved to the inside of the trunk. It On the other hand, the luggage link mechanism opens the trunk lid.
By linking the roof link mechanism and the luggage link mechanism, the roof panel and the back window are stored in the open trunk. At this time, the roof link mechanism and the luggage link mechanism are operated by the connecting means in a state of being connected to each other through the back window or the back window and the trunk lid. The connecting means can share the entire roof link mechanism and the luggage link mechanism to ensure the rigidity of each mechanism, for example, in the twisting direction. Compared to the case where the roof link mechanism and the luggage link mechanism are operated separately by the connecting means, the rigidity of each mechanism may be set to be low, which enables the luggage link mechanism to be downsized, and the trunk inside the trunk. The luggage space can be widened.

Further, when the trunk lid is opened with the roof panel and the roof link mechanism stored in the trunk, the trunk lid rotates upward of the vehicle and a part of the luggage link mechanism is moved as the trunk lid moves. Also moves above the vehicle. Since the back window and the trunk lid or the luggage link mechanism are connected by the connecting means, the back window also moves upward in conjunction with the upward rotation of the trunk lid.

Further, the roof panel and the like, which are overlapped with the back window and are both housed in the trunk, are also moved upward. By the above operation, the so-called frontage of the trunk, which is composed of the edges of the stored roof panel, back window, etc. and the opening edge of the trunk, can be widened, and the loading and unloading of luggage into and from the trunk can be performed easily and smoothly. It will be possible.

More preferably, as shown in the characteristic item 2,
"The connecting means comprises a plurality of connecting members rotatably connected to each other, at least one of the plurality of members is rotatably connected to the back window, and at least one of the remaining members is the trunk lid. Alternatively, the roof opening / closing device according to feature 1 is configured to be rotatably connected to any one of the luggage link mechanisms.

With the above structure, the rotational movement and the linear movement of the back window can be combined.

Further, as described in characteristic item 3, "the connecting means has a first connecting member whose one end is rotatably connected to the back window and one end is rotating to the other end of the first connecting member. It is preferable that the roof opening / closing device according to feature 2 is characterized in that the roof opening / closing device is characterized by comprising a second connecting member that is freely connected and has the other end rotatably connected to the trunk lid.
