<p>A vehicle door latch has a forkbolt (24), a detent, a release mechanism that moves the detent (26) to release the forkbolt (24), a lock mechanism for disabling the release mechanism, an inside lock lever (96) for operating the lock mechanism and a double lock for disabling the inside lock lever (96). The detent (26) is moved by an intermittent lever (46). A composite lock lever (82, 84) moves the intermittent lever (46) back and forth between an unlock position where the intermittent lever (46) drives the detent to release the forkbolt (24) and a lock position where the intermittent lever (46) free wheels with respect to the detent (26). The intermittent lever (46) is pivotally connected to an unlatching lever (44) of the release mechanism that is operated by inside (68) and outside (60) release levers. The composite lock lever (82, 84) includes a lower lock lever (82), an upper lock lever (84), and a spring (86) that stores energy when the lower (82) pivots with respect to the upper lock lever (84). The inside lock lever (96) and an outside lock lever (106) operate the lower lock lever (82). When engaged, the double lock assembly blocks the upper lock lever (84) so that the vehicle door latch cannot be unlocked by the inside lock lever (96).</p> |
