Abstract

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.
