Abstract:
A door lock system includes a ratchet, a latch, a ratchet lever that disengages the ratchet from the latch when a disengaging operation is performed, a first link lever that moves to and from a transmitting position and a non-transmitting position, wherein when the first link lever is at the transmitting position, the ratchet lever is allowed to disengage the ratchet from the latch, and when the first link lever is at the non-transmitting position, the ratchet lever is inhibited from disengaging the ratchet from the latch, a second link lever that is pivotally coupled to a base end of the first link lever at a base end of the second link lever and that moves in response to a locking operation and an unlocking operation. A distal end of the first link lever and a distal end of the second link lever constantly overlap each other.
