    • A motor-vehicle door latch has a door-mounted fork displaceable between an open and a fully latched position and through an intermediate semilatched position and a body-mounted door bolt engageable with the fork and retainable thereby only in the semilatched and fully latched positions. A door-mounted pawl can pivot about a pawl axis between a holding position engaging and retaining the fork in the fully latched and semilatched positions and a freeing position permitting the fork to move freely between its positions. A controller is connected to a servomotor in turn coupled to the door bolt for displacing same between an outer and an inner position so that, when the bolt is engaged with the fork in the fully latched position, movement of the bolt into the inner position pulls a door carrying the latch tightly closed. A switch lever can pivot about the pawl axis. Interengaging formations on the switch lever, on the pawl, and on the fork displace the switch lever into a first position with the fork in the semilatched and open positions and with the pawl in the open position and displace the switch into a second position with the fork in the fully latched position. A switch between the control means and the switch lever prevents operation of the servomotor except in the second position of the switch lever.
    • 机动车门闩具有可在打开和完全闩锁位置之间移动并通过中间半固定位置的门安装的叉和能够与叉接合并且仅由半固定和完全锁定位置保持的车身安装的门螺栓。 门安装的棘爪能够绕着卡爪轴线转动,该保持位置在完全锁定和半固定的位置处与叉子保持接合并保持,并且允许叉子在其位置之间自由移动的释放位置。 控制器连接到伺服电动机,然后又连接到门螺栓,用于在外部位置和内部位置之间移位,使得当螺栓在完全闩锁的位置与叉接合时,螺栓进入内部位置拉动 一个携带闩锁的门紧密关闭。 开关杆可围绕棘爪轴线枢转。 开关杆,棘爪和叉子上的入口结构将开关杆移动到第一位置,其中叉子处于半固定和打开位置,并且棘爪处于打开位置,并将开关置于第二位置 叉子处于完全锁定位置。 控制装置和开关杆之间的开关防止除了开关杆的第二位置之外的伺服电机的操作。
