Description

[Detailed description of the invention] The present invention relates to a sliding roof structure for a vehicle.

In a sliding roof structure for a vehicle in which the opening/closing body is moved to the rear of the roof to open the roof opening, a so-called external sliding sliding roof device, the opening and closing body is moved to the rear of the roof to open the roof opening. It is desirable to ensure as large a length as possible from front to back.

As such an external sliding type sliding roof device, Japanese Utility Model Application Publication No. 161418/1983 is known.

In Utility Model Application No. 53-161418, a link is pivotally attached to the roof part that forms the rear edge of the opening, and the tip of this link is engaged with a guide rail on the side of the opening/closing body, so that the opening/closing body can be opened with the link erected. It is moved to the rear of the roof.

However, in such a structure, the length of the guide rail on the opening/closing body side becomes the movement range of the opening/closing body, so in order to ensure a large front-to-back length of the opening when opening, it is necessary to extend the guide rail over the entire length of the opening/closing body. However, there was a problem in that the weight of the opening/closing body increased.

The present invention has been devised to solve the above-mentioned problems, and an object of the present invention is to provide a sliding roof for a vehicle that can secure a large longitudinal length of the opening when opened while reducing the weight of the opening/closing body. It is there to provide structure.

To achieve the above object, the present invention includes: an opening formed in a vehicle body roof; an opening/closing body that can freely open and close the opening; a tilt-up mechanism that tilts up the rear end of the opening/closing body; and a vehicle body side guide provided on the vehicle body side. a rail, an opening/closing body side guide rail provided on the opening/closing body side, and slidably engaging with each of the guide rails to guide the opening/closing movement of the opening/closing body onto the rear roof when the rear end of the opening/closing body is tilted up. A connecting body is provided, and the connecting body extends in the front-rear direction so that the rear end of the connecting body is located on the rear roof when the opening/closing body is opened.

According to such a configuration, the movement range of the opening/closing body is determined by the movement range of the coupling body on the vehicle body side guide rail, the movement range of the coupling body on the opening/closing body side guide rail, and the length of the coupling body portion located on the rear roof. Therefore, the range of movement of the opening/closing body in the front-back direction can be increased, and the length of the opening in the front-back direction when opened can be ensured to be large.

Further, it is no longer necessary to provide the opening/closing body side guide rail over the entire length of the opening/closing body, so that the opening/closing body side guide rail can be shortened and the weight of the opening/closing body can be reduced.
