    摘要： A latch assembly includes a chassis and a rotatable claw-type latch bolt moveably mounted on the chassis. The latch bolt has a closed position for retaining a striker and an open position for releasing the striker. The latch bolt is provided with a latch abutment remote from a center of rotation. The latch assembly further includes a pawl rotatable about a pawl axis and having an engaged position for holding the latch bolt in the closed position and a disengaged position that allows the latch bolt to move to the open position. The latch assembly includes an eccentric arrangement defining a first axis and the pawl axis remote from the first axis. The latch assembly also includes a reset lever rotatably fixed to the eccentric arrangement for mutual rotation with the eccentric arrangement about the first axis. The latch assembly includes a biasing lever configured to transmit a biasing force to the reset lever at a position remote from the first axis and to the latch bolt via the latch abutment. The latch assembly includes a biasing device arranged to apply the biasing force to the biasing lever. The latch assembly is configured such that when the pawl retains the latch bolt in the closed position, the biasing lever applies a force to the reset lever to promote disengagement of the pawl, and such that when the pawl is disengaged, the biasing lever promotes the rotation of the latch bolt into the open position.

    摘要翻译： 闩锁组件包括底盘和可移动地安装在底盘上的可旋转爪型闩锁螺栓。 闩锁螺栓具有用于保持撞针的关闭位置和用于释放撞针的打开位置。 闩锁螺栓设置有远离旋转中心的闩锁支座。 闩锁组件还包括可围绕棘爪轴线旋转并且具有用于将闩锁闩锁保持在关闭位置的接合位置的棘爪和允许闩锁闩锁移动到打开位置的脱离位置。 闩锁组件包括限定第一轴线的偏心装置和远离第一轴线的棘爪轴线。 闩锁组件还包括可旋转地固定到偏心装置的复位杆，用于使偏心装置围绕第一轴线相互旋转。 闩锁组件包括偏置杆，所述偏压杆构造成在远离第一轴线的位置处将偏置力传递到复位杆，并且经由闩锁邻接件传递到闩锁螺栓。 闩锁组件包括偏置装置，其被布置成将偏置力施加到偏置杆。 闩锁组件被构造成使得当棘爪将闩锁闩锁保持在关闭位置时，偏置杆向复位杆施加力以促使棘爪脱离，并且使得当棘爪脱离时，偏置杆促使 闩锁螺栓旋转到打开位置。
