Vehicle latch
A latch includes a housing, a fork bolt operably coupled to the housing and pivotal between an unlatched position, a primary latched position, and a secondary latched position, and a detent lever operably coupled to the housing and arranged to cooperate with the fork bolt. A drive link is operatively connected to the fork bolt and to the detent lever. An override lever is operably coupled to the drive link. A manual release lever is operably coupled to the override lever. The manual release lever is movable between a rest position and a release position. The drive link is automatically moved out of a path of rotation of the fork bolt when the manual release lever is moved to the release position.
1. A method of operating a latch, the latch including a fork bolt, and a detent lever, the method comprising:
providing a drive link selectively engageable with the fork bolt and the detent lever;
providing an override lever movably mounted about a post, the override lever being operably coupled to the drive link;
providing a manual release lever mounted to the post, the manual release lever being rotatable relative to the post and the override lever, wherein the manual release lever is operably coupled to the override lever as the manual release lever rotates about the post;
rotating the manual release lever about the post into engagement with the detent lever;
pivoting the detent lever out of engagement with the fork bolt via rotation of the manual release lever about the post, wherein disengaging the detent lever from the fork bolt allows the fork bolt to rotate along a path of rotation to an unlatched position;
translating the override lever relative to the post and the manual release lever in response to rotation of the manual release lever about the post; and
moving the drive link out of a path of rotation of the fork bolt in response to translating the override lever relative to the post, wherein the fork bolt is freely rotatable to an unlatched position when the fork bolt is disengaged from the detent lever and the drive link is separated from the path of rotation of the fork bolt.
2. The method of claim 1 , wherein rotating the manual release lever includes rotating a cam surface of the manual release lever into engagement with a contoured surface of the override lever.
3. The method of claim 2 , wherein the override lever is operably coupled to the drive link such that translating the override lever applies a force to the drive link to move the drive link out of the path of rotation of the fork bolt.
