A door opening and closing apparatus for a vehicle, includes a latch mechanism adapted so as to retain a vehicle door in a closed state relative to a vehicle body, an outside lever provided within a space formed inside of the vehicle door so as to be positioned closer to an interior of the vehicle and linked to an outside handle adapted to be rotatably supported by the vehicle door, a detection switch detecting an operation to the outside handle when the outside lever contacts the detection switch in response to an operation of the outside lever, and a release device releasing a retention of the vehicle door in the closed state by means of the latch mechanism by the release device actuating the latch mechanism when a rotational operation of the outside handle is detected by the detection switch while the vehicle door is in a locked state.

Door opening and closing apparatus for vehicle

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.

Door closing apparatus

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.

Door lock apparatus for a vehicle

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. The drive mechanism. includes a guide wall face arranged so as to face the operating portion and a biasing member for biasing the operating portion to be pressed against the guide wall face. The operating portion can be separated from the guide wall face by an external force greater than a biasing force of the biasing member.

Door lock device for a vehicle

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.

Door lock system

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.
