Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide rail structure for a sunroof device used in vehicles such as passenger cars.

[0002]

2. Description of the Related Art As a conventional sunroof device, there is a slide targa roof type device as disclosed in Japanese Patent Laid-Open No. 5-22124. In this type,
An opening is formed corresponding to the front seat between the windshield mounting front frame that is fixed to the vehicle body and the fixed roof that is fixed to the rear frame that is fixed to the vehicle behind the front door. A pair of left and right fixed rails are arranged on the lower side, a movable rail is supported on the fixed rail so as to be movable back and forth, and a movable roof that opens and closes the opening by forward and backward movement is provided on the fixed rail. Is provided with a guide groove, and the movable rail is provided with a group of rollers engaged with the guide groove of the fixed rail.

[0003]

In the above-mentioned prior art, since the roller group provided over the entire length of the movable rail engages with the fixed rail, when the opening is open, that is, the movable roof is inside the fixed roof. The vertical support of the movable roof is relatively stable when it is stored in, but when the movable rail protrudes forward to close the opening, the number of rollers acting for movement gradually decreases. However, the opening / closing resistance may increase, or vertical play may occur.

Further, since the fixed rail and the movable rail support the movable roof only by the engagement of a pair of rollers and the guide groove in the vertical direction, it is difficult to increase the moving distance of the movable rail and the floating occurs. In some cases, the supporting strength is low. Further, since the position between the roller and the guide groove is not regulated in the left-right direction, the movable rail may have left-right rattling.

A first object of the present invention is to form a movable rail in a gate-shaped cross-section covering a fixed rail, and a guide groove for engaging a roller provided in the front portion of the fixed rail on the upper side of each left and right inner surface of the movable rail. By forming a guide groove that engages with a roller provided at the front of the movable rail on the lower side of each outer surface of the fixed rail, the movable roof is prevented from rattling in the vertical direction at each opening and closing position. Can be opened and closed smoothly,
Another object of the present invention is to provide a guide rail structure for a sunroof device, which enables a movable rail to have a long moving distance.

A second object of the present invention is to make the outer diameters of the rollers of each group of the fixed rail and the movable rail smaller than the vertical gaps of the guide grooves with which they engage, and to make the rollers of each group the guide grooves. By dividing the support roller that comes into contact with the upper and lower surfaces and the regulation roller and arranging the support rollers on both sides of the regulation roller in the front-rear direction, it is possible to strongly support the downward moment applied to the front part of the movable rail and prevent lifting. (EN) Provided is a guide rail structure for a sunroof device.

A third object of the present invention is to provide, on the rear part of the movable rail and the front part of the fixed rail, left and right position restricting shoes capable of sliding contact with the inner surfaces of the respective guide grooves.
(EN) It is possible to provide a guide rail structure of a sunroof device capable of preventing the movable rail from rattling on the left and right.
