    • A latch assembly includes a latch movable between released and restrained positions and a latch spring biasing toward the released position. A first lever is movable between open and closed positions, corresponding to the released and restrained positions, respectively. A first lever spring biases toward the closed position. A second lever is movable between unlocked and locked positions, corresponding to the first lever open and closed positions, respectively. A second lever spring biases toward the locked position. An active material based actuator selectively moves the second lever from the locked to unlocked position in response to an activation signal. A primary activation mechanism selectively produces the activation signal without a mechanical connection to the passenger compartment. An auxiliary activation mechanism does not rely on the vehicle power system. A key or portable energy storage device may cause the activation signal from the primary or auxiliary activation mechanism.
    • 闩锁组件包括可在释放和限制位置之间移动的闩锁和朝向释放位置偏置的闩锁弹簧。 第一杆可以在打开位置和关闭位置之间分别对应于释放和限制位置。 第一杆弹簧偏向关闭位置。 第二杆分别在解锁和锁定位置之间移动,分别对应于第一杆打开和关闭位置。 第二杆弹簧偏向锁定位置。 基于活动材料的致动器响应于激活信号选择性地将第二杠杆从锁定位置移动到解锁位置。 主激活机构选择性地产生激活信号,而不与机舱连接。 辅助启动机构不依赖于车辆动力系统。 钥匙或便携式能量存储装置可以引起来自主要或辅助激活机构的激活信号。
