Latch Devices for Vehicles

Abstract

To keep a slide-door restrained and an opening part of the door closed by the slide-door by preventing the engagement once engaged from being disengaged when load is applied on the slide-door from the inside of the vehicle toward the outside of the vehicle.SOLUTION: This is to provide a latch device for vehicles which includes a latch member 30 rotatably supported between the restraining position that restrains a part to be restrained 12 of a striker 10 and the releasing position that releases the part to be restrained 12, and a ratchet member 40 movably supported between the restricting position that restricts the movement of the latch member 30 to the releasing position and a restriction releasing position apart from the movement locus of the latch member 30. There is an engagement recess part 37 which has made a tooth surface to be formed intersecting the tangential direction of the outer peripheral part on the latch member 30 and there are an engagement arm part 43 with a locking claw 47 of the ratchet member 40 and a movement restriction part 44 positioned on the other side across a ratchet shaft 40C from the engagement arm part 43, and the engagement arm portion 43 is set to weigh more than the movement restriction part 44 in regards to weight distribution.SELECTED DRAWING: Figure 8

Description

technical field [0001] The present invention relates to a latch device for a vehicle that locks and unlocks a sliding door that opens and closes a door opening by sliding. Background technique [0002] Conventionally, the movement of the sliding door is restricted so that the sliding door does not accidentally open when a load is applied to the sliding door from the interior of the vehicle to the exterior of the vehicle. [0003] For example, Japanese Patent Application Laid-Open No. 2008-101336 proposes a structure of a latch device including a latch that is engaged with a striker disposed on the vehicle body when an impact is input, and a latch that is engaged with a striker disposed on the vehicle body. Engaging pawls. [0004] The sliding door for a vehicle is configured to slide on the outer side of the vehicle body, and to enter obliquely with respect to the door opening when the door opening is closed. Therefore, in the structure of Japanese Patent Application Laid-...

AI Technical Summary

Problems solved by technology

Therefore, in the structure of Japanese Unexamined Patent Publication No. 2008-101336, due to the difference in the direction of the load applied to the sliding door for a vehicle, the sliding door for a vehicle may not move in the vehicle width direction but move obliquely, causing the latch and the pawl to disengagement, causing the sliding door to open
