Closure latch and release mechanism

摘要

A latch assembly includes a forkbolt movable between a released position, allowing opening of a closure, and a restrained position, preventing opening of the closure. A forkbolt spring is configured to bias the forkbolt toward the released position. A primary detent is mounted with respect to the forkbolt and movable between an open position, allowing the forkbolt to move into the released position, and a closed position, not allowing the forkbolt to move into the released position. A secondary detent is movable between an unlocked position, allowing the primary detent to move into the open position, and a locked position, preventing the primary detent from moving into the open position. An actuator selectively moves the secondary detent from the locked position to the unlocked position.

主权项

1. A latch assembly for a vehicle having a closure, comprising:
a forkbolt movable between a released position and a restrained position, wherein the released position allows opening of the closure and the restrained position prevents opening of the closure; a forkbolt spring operatively attached to the forkbolt and configured to bias the forkbolt toward the released position; a primary detent mounted with respect to the forkbolt and movable between an open position and a closed position, wherein the open position of the primary detent allows the forkbolt to move into the released position and the closed position of the primary detent does not allow the forkbolt to move into the released position; a primary detent spring operatively attached to the primary detent, wherein the primary detent spring is configured to bias the primary detent toward the open position; a secondary detent mounted with respect to the primary detent and movable between an unlocked position and a locked position, wherein the unlocked position of the secondary detent allows the primary detent to move into the open position and the locked position of the secondary detent will not allow the primary detent to move into the open position; a tension spring operatively attached to the secondary detent and configured to bias the secondary detent toward the locked position; and an actuator configured to selectively move the secondary detent from the locked position to the unlocked position in the presence of an activation signal.
