Abstract: A door closing apparatus includes a latch mechanism operated for opening or closing a door of a vehicle, a driving mechanism transmitting a driving force to the latch mechanism to operate the latch mechanism, a first lever rotatably disposed about a first rotational axis and rotating in one direction in response to transmission of an operation force of a door handle to the first lever so that the latch mechanism is controlled at the unlatched state, a second lever having an engaging portion which engages with the first lever and rotatably disposed about a second rotational axis being different from the first rotational axis. The second lever rotates in the one direction about the second rotational axis in response to a rotation in the one direction of the first lever to interrupt transmission of the driving force from the driving mechanism to the latch mechanism.

Abstract: 1. A door closing apparatus includes a latch mechanism operated for opening or closing a door of a vehicle, a driving mechanism transmitting a driving force to the latch mechanism to operate the latch mechanism, a first lever rotatably disposed about a first rotational axis and rotating in one direction in response to transmission of an operation force of a door handle to the first lever so that the latch mechanism is controlled at the unlatched state, a second lever having an engaging portion which engages with the first lever and rotatably disposed about a second rotational axis being different from the first rotational axis. The second lever rotates in the one direction about the second rotational axis in response to a rotation in the one direction of the first lever to interrupt transmission of the driving force from the driving mechanism to the latch mechanism.

Abstract: A driving mechanism includes: a drive gear fixed to a motor; a sun gear rotatably provided and having a gear portion engaged with the drive gear; a ring gear coaxial with the sun gear and locked not to rotate relative to the sun gear and being allowed to rotate relative to the sun gear; a planetary gear engaged with the sun gear and the ring gear; a planetary carrier coaxial with the sun gear and connected to the planetary gear, the planetary carrier outputting force in response to rotation and revolution of the planetary gear associated with rotation of the sun gear and relative to the ring gear locked not to rotate. A central engaged portion of the driving gear and the gear portion and a central engaged portion of the sun gear, the ring gear and the planetary gear are arranged on the same plane.

Abstract: A vehicle door lock apparatus includes a latch, an operating member for performing a lock operation for rotating the latch to a lock position by being moved from a neutral position to a first position and an unlock operation for rotating the latch to an open position by being moved from the neutral position to a second position, a control unit for switching a moving direction of the operating member, an operated member for being operated along with the operating member moved to the second position, a restricting member for restricting a movement of the operated member in a predetermined position, and a detecting means for detecting the operated member being positioned adjacent to the predetermined position. The control unit enters a standby mode through a process of bringing the operating member to return to the first or second position side after the unlock operation or the lock operation is completed.

Abstract: A vehicle door lock device includes a latch being rotatable between an open position in which the latch is disengageable from a strikes and a lock position in which the latch is prohibited to disengage from the striker, and an actuator for rotating the latch toward the lock position and including an operating portion engageable with an operated portion formed at the latch and a drive mechanism for moving the operating portion being in an engaged state with the operated portion along a predetermined path.

Abstract: A door lock system has a closing mechanism for bringing an ajar condition of a door into a fully closed condition. The fully closed condition of the door is locked for the sake of safety by the locking operation of a locking-and-unlocking mechanism. The locked condition of the door is released by an unlocking operation of the locking-and-unlocking mechanism. Moreover, by actuating a double lock mechanism, the door under the locked condition is further brought into a double-looked condition under which the unlocking operation of the locking-and-unlocking mechanism cannot be established. The closing mechanism, the locking and-unlocking mechanism, and the double lock mechanism are driven by a common electric motor thus allowing the door lock mechanism to be reduced in size and manufactured less expensively.

Abstract: A door lock assembly having a reduced size. The door lock assembly comprises: a closer mechanism for bringing a vehicle door from a partially closed state to a completely closed state; a locking/unlocking mechanism for bringing the vehicle door in the completely closed state to a locked state and an unlocked state; and a drive mechanism including a single motor acting as a drive source for actuating the closer mechanism and the locking/unlocking mechanism.
