Title:
SUDDEN CLOSURE PREVENTING DEVICE FOR VEHICULAR SLIDE DOOR
Document Type and Number:
Japanese Patent JP3404687
Kind Code:
B2
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.
