A vehicle door latch with a one-motion door opening mechanism, a free-play antitheft mechanism and a clutch mechanism

摘要

A vehicle door latch device comprises: a one-motion door opening mechanism transmitting an opening movement of an inside open handle 19 both to a lock lever 23 and to a ratchet 4; a free-play type antitheft member 60; and a clutch mechanism 39 provided between the one-motion mechanism and the inside open handle 19. The clutch mechanism 39 is so connected to the antitheft member 60 that the clutch mechanism is displaced to an uncoupling state where it does not transmit the opening movement to the one-motion mechanism when the antitheft member 60 is changed over to an antitheft position, and that the clutch mechanism 39 is displaced to a coupling state where it transmits the opening movement to the one-motion mechanism when the antitheft member 60 is changed over to an antitheft cancelled position. Thus when the antitheft member is in the antitheft position, it is not possible for either of the inside door button or the inside door handle to unlock and release the latch.
