Abstract

PROBLEM TO BE SOLVED: To ensure safety and prevent the occurrence of a breakage by providing a cushion body unit on a body before a total closure position on the operation locus of a slide door, and causing the cushion body unit to come in contact with a stopper on the slide door only at the sudden closure thereof. SOLUTION: A body is provided with a cushion body unit 6 having a guide rail 8, a cam roller 9 and a cushion body block 10, while the reverse side of a slide door is provided with a stopper lever unit 7 having a stop lever 13 journalled thereto under horizontal energization with a spring 14 at all times. When the slide door moves in a closing direction, a guide roller concentric with a pin 12 enters the guide rail 8 and cam surface 15 on the upper part of the stop lever 13 collides with the cam roller 9. thereby tilting the stop lever 13 in the counterclockwise direction. In the gradual motion of the slide door, the spring 14 resets the stop lever 13 to a horizontal state, and the slide door passes without coming in contact with the cushion body block 10. At the time of the sudden motion, the rightmost end of the stop lever 13 is sprung up over the level of cam action and then the slide door collides with the cushion body block 10. An inertia force is thereby absorbed, and the stop lever 13 is reset to a horizontal state with the spring 14 for moving the slide door to a totally closed position.

2. Description of the Related Art A conventional slide door of this type is provided with an upper rail, a lower rail, and a guide rail facing the front-rear direction at an upper edge and a lower edge of a door opening, and a waist on a side surface of a vehicle body. By engaging roller units provided on the upper, lower, and middle portions of the rear surface of the door with the upper rail, the lower rail, and the guide rail, the sliding door can be freely opened and closed in the front-rear direction.

Since the sliding door has a relatively large opening area and does not swing out of the door, it is convenient for passengers to get on and off and to load and unload luggage even in places where there is no room on the side.

[0004]

However, if this kind of sliding door is released on a slope or the like in a state where the door is not checked, there is a danger that the hand may be suddenly closed and the hand may be caught.

[0005] Further, when a closure is provided in which the striker is forcibly moved to move the door to the fully closed position after the door lock is in the fully latched state, the door lock is provided without the seal rubber. However, there is a drawback that a large force is applied to the door lock and the striker since the door is fully latched.

SUMMARY OF THE INVENTION It is an object of the present invention to secure safety and prevent damage to a door lock and a striker by stopping the slide door before the slide door is fully closed even if the slide door is suddenly closed.

[0007]

According to the present invention, the above-mentioned problem is solved as follows. (1) A device for preventing sudden closing of a sliding door for a vehicle, which is slidably movable in the front-rear direction along a side surface of the vehicle body. A body block is provided, and the slide door is provided with a stopper lever which comes into contact with the buffer block by a quick closing operation and does not come into contact with a gentle closing operation.

(2) In the above item (1), a cam roller is disposed on a side surface of the vehicle body, and a stopper lever pivotally attached to the slide door is provided with a cam surface on which the cam roller rides.
The stopper lever tilted by the cam action collides with the buffer block in a state where the stopper lever does not return from the tilting due to the sudden closing operation.

(3) In the above item (1) or (2), the stopper lever pivotally attached to the slide door is normally urged to a horizontal position by a spring, and against the action of the spring during a cam action. Try to tilt.
