摘要： A vehicle door latch has a forkbolt, a detent that holds the forkbolt in a latched position and a power operated release mechanism that moves the detent to release the forkbolt. The power operated release mechanism includes a power unlatching lever and a motor driven actuator having a jackscrew for moving the power unlatching lever via a slide, bell crank lever and bell crank link that provide a toggle enhancement. A mechanical override lever is provided to move the power unlatching lever in the event of power failure.

摘要： A vehicle door latch has a forkbolt, a detent that holds the forkbolt in a latched position, a release mechanism that moves the detent to release the forkbolt and a lock mechanism for disabling the release mechanism. The detent is moved by an intermittent lever that is part of the release mechanism and part of the locking mechanism. A lock lever forming part of the lock mechanism moves the intermittent lever back and forth between an unlock position where the intermittent lever drives the detent to release the forkbolt and a lock position where the intermittent lever free wheels with respect to the detent. The intermittent lever is pivotally connected to an unlatching lever of the release mechanism that is operated by inside and outside release levers. The lock lever includes a lower lock lever, an upper lock lever and a spring that stores energy when the lower lock lever pivots with respect to the upper lock lever. The lock mechanism includes an inside lock lever and an outside lock lever for operating the lower lock lever. The door latch also includes a motor driven actuator assembly for operating the lock mechanism and a double lock assembly for disabling the lock assembly so that the door latch cannot be unlocked by the inside lock lever.
