摘要： A switch assembly of a vehicle door latch device, the switch assembly includes: a latch switch detecting a position of a latch, the latch being pivotally supported by a latch shaft to be engaged with a striker; a ratchet switch that detecting a position of a ratchet, the ratchet being pivotally supported by a ratchet shaft to be engaged with the latch and prevented reverse rotation of the latch; and a one common switch case that the latch switch and the ratchet switch are installed in the one common switch case. The latch shaft and the ratchet shaft are arranged to be isolated across a striker moving trajectory of the striker. The one common switch case is arranged on a latch body on one side of a striker moving trajectory.

摘要： A vehicle door latch device includes: a latch unit configured to keep a vehicle door in a door-closed state by engaging with a striker of a vehicle body; a power release mechanism configured to make the vehicle door openable by releasing engagement between the latch unit and the striker; a disengagement mechanism installed in a path coupling the power release mechanism with the latch unit, the disengagement mechanism being configured to be switched between a connected state and a disconnected state; and a lever configured to switch the disengagement mechanism from the connected state to the disconnected state. The lever is configured to be connectable to both of a full-open position holder, operating when the vehicle door reaches a full-open position by door-opening slide, and a disengagement operating unit for manual operation.

摘要： An opening and closing device of a vehicle sliding door includes: a fully closed latch mechanism; a fully opened latch mechanism; a power releaser; a power closer; a canceler; a lock mechanism; and a relay control mechanism that includes an inner handle. The lock mechanism, the power releaser, and the canceler are disposed in the fully closed latch mechanism. The relay control mechanism includes a handle lever configured to, when a door opening operation is performed on the inner handle, rotate in a first direction to unlatch the fully closed latch mechanism and activate the cancel mechanism, and when a door closing operation is performed on the inner handle, rotate in a second direction to unlatch the fully opened latch mechanism. The inner handle is pivotally supported by the handle case of the relay control mechanism so as to be rotatable in two directions.

摘要： A vehicle door operation device includes an inside handle, a full open unlocking lever for transmitting a closing operation of the inside handle to a full open door latch device, and a full closure unlocking lever for transmitting an opening operation of the inside handle to a full closure door latch device. The inside handle has first and projecting portions, and when the inside handle rotates in a first direction by the closing operation, the first projecting portion is brought into abutment with the full open unlocking lever to enable the full open unlocking lever to operate, whereas when the inside handle rotates in a second direction by the opening operation, the second projecting portion is brought into abutment with the full closure unlocking lever to enable the full closure unlocking lever to operate.

摘要： A vehicle door operating device includes an opening inside lever connected to an inside handle in a door inside a vehicle, a childproof lock lever that moves between a childproof unlock position and a childproof lock position; a switch lever, a childproof sensor and a single engagement pin. When the childproof lock lever is in the childproof lock position, opening action of the inside handle cannot be transmitted to a door latch device, but can be transmitted to the switch lever. When the childproof lock lever is in the childproof unlock position, releasing action of the opening inside lever can be transmitted to door latch devices for holding a door closed via a single engagement pin, but cannot be transmitted to the switch lever. When the childproof lock lever is in the childproof lock position, the releasing action of the opening inside lever cannot be transmitted to the door latch device via the engagement pin, but can be transmitted to the switch lever.

摘要： A vehicle-door opening and closing device includes: a latch unit configured to keep a vehicle door in a half latched state or a fully latched state; a power close mechanism configured to displace the vehicle door from the half latched state to the fully latched state; a power release mechanism configured to release the fully latched state to bring the vehicle door to an openable state; and a drive gear configured to be driven by a motor. The power release mechanism is configured to be actuated with a drive force of the drive gear. A return switch configured to be switched upon driving in a predetermined drive range sufficient to complete actuation of the power release mechanism is placed near the drive gear. The motor is configured to return the drive gear based on a signal from the return switch.
