DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door guide apparatus for an automobile, in which a suspended and supported door is pulled toward a vehicle body at a terminal end of a closing operation and is closed.

[0002]

2. Description of the Related Art In a conventional slide door guide apparatus for a vehicle, the end of a guide rail of a door is curved toward the inside of a vehicle in a horizontal plane, and a roller of a front hanging means of the door is used for closing the door. The door is pulled toward the vehicle body by entering the curved end portion at the end portion, thereby tightening the door and the vehicle body frame.

[0003] However, if the rails are bent inward, the floor area in the vehicle is reduced accordingly, and the passenger space and luggage storage space in the vehicle are reduced, which is also a problem in loading and unloading luggage. Also, the work of mounting the rail is troublesome.

[0004]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a sliding door guide apparatus for an automobile, which allows a door to be sufficiently tightened without having to curve the end of the rail inward in a horizontal plane. is there.

[0005]

Means for Solving the Problems Hereinafter, a description will be given using reference numerals in the accompanying drawings. In a sliding door guide device for a vehicle according to the present invention, a first link 13 and a second link 14 of the same length are arranged at an intermediate point. The first link 13 is connected by a pivot 15
The upper end of the first link 13 is connected to the holder 7 of the upper roller 5 by the pivot 9, the lower end of the first link 13 is connected to the lower part of the support plate 11 on the back of the door mounting plate 18 by the pivot 15, The lower end is connected to the holder 8 of the lower roller 6 by the pivot 10 and the upper end of the second link 14 is connected to the support plate 1.
, The upper roller 5 is fitted to the upper rail 3 fixed to the vehicle body side, and the lower roller 6
Into the lower rail 4 fixed to the vehicle body 1, and the lower end of the lower rail 4 on which the lower roller 6 rolls at the end of the closing operation of the door 2 is moved from the end of the upper rail 3.
Bend down in the vertical plane to separate .

[0006]

The sliding door guide device for an automobile is provided two at the upper part of the door 2 and one at the lower part. When the door 2 is closed, the rollers 5 and 6 roll toward the ends of the upper rail 3 and the lower rail 4, and when reaching the end, the distance between the upper rail 3 and the lower rail 4 increases, and the link mechanism closes. Operating in the direction, the door 2 approaches the vehicle body 1 and the door 2 is tightened.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the actual turning example shown in FIGS. 1 to 5, the upper rail 3 is fixed to the vehicle body 1 straight, and the guide groove 1 extends in the longitudinal direction.
9 are provided, and guide edge plate portions 20 and 21 project from the upper and lower side edge portions in parallel with the guide groove 19. The lower rail 4 is disposed parallel to the upper rail 3 in a vertical plane, and has a left end curved in the vertical plane. The lower rail 4 is provided with a guide groove 22 in the length direction, and also has guide edge plate portions 23 and 24 protruding from the upper and lower edges of the curved portion in parallel with the guide groove 22.

The shaft support plate 11 has an L-shaped cross section, and has an escape slot 12 in the longitudinal direction of the pivotal portion of the pivot 17.
The pivot 17 can move freely when the link mechanism is opened and closed.

[0009]

As described above, according to the present invention, since the rails are formed straight in the horizontal plane, the floor area in the vehicle can be maximized and effectively used, and the cabin space and luggage of the rear seats can be utilized. The storage space can be expanded. Further, since there is no curved portion in the horizontal plane, the shape and structure of the rail mounting portion of the vehicle body are simplified, and the rail mounting operation can be performed without trouble.
