Actuator apparatus and related methods for use with vehicle locks are disclosed. A disclosed locking system for a vehicle includes a movable component of the vehicle and a lock operatively coupled to the movable component. The locking system also includes an actuator assembly. The actuator assembly includes a housing coupled to a vehicle body, an actuator supported by the housing, and a linkage mechanism connecting the actuator to the lock. The locking system also includes an input device supported by the housing. Activation of the input device causes the actuator to change a state of the lock.

A lock includes a base and movable element connected to a handle operable by a user and movable between a first position corresponding to an open condition of the handle and a second position corresponding to a closed condition. An operating element is rotatably mounted on the base and connected to a device for releasing a closing panel, and is rotatable between a first position corresponding to an open condition of the panel and a second position corresponding to a closed condition. A transmission acts between the movable an operating elements and kinematically connects the movable and operating elements such that movement of the movable element causes rotation of the operating element. An uncoupling device acts on the transmission for disengaging kinematically, and in a controlled way, the movable element from the operating element to disable actuation of the operating element by the movable element.

A vehicle door attached to a vehicle body includes a bracket structure disposed between an interior-side panel and an exterior-side panel to support a door lock portion. The bracket structure has an interior-side extension portion disposed on an interior-side and joined to the interior-side panel, and an exterior-side extension portion disposed on an exterior-side and joined to the exterior-side panel. Extension portions extend in an upper-lower direction. As an alternative, a vehicle door includes a middle panel disposed between an inner panel and an outer panel, and a bracket structure disposed between the inner panel and the middle panel to support the door lock portion. The bracket structure has a front extension portion disposed frontward and joined to the inner panel, and a rear extension portion disposed rearward and joined to the middle panel. Extension portions are disposed in a front-rear direction of a vehicle and extend upward.

A vehicle door latch device includes: a latch body including: a latch secured by a latch shaft on a rear surface side of the latch body, the latch being configured to engage with a striker; a ratchet secured by a ratchet shaft on the rear surface side of the latch body, the ratchet being configured to engage with the latch; and a striker advancing path into which the striker advances relatively; a motor configured to release the ratchet from the latch; and an actuator case provided continuously on top of the latch body, the actuator case being configured to accommodate the motor.

A power unit for a powered cinching mechanism with a favorable level of operational noise is provided. A door latch apparatus includes latch unit and power unit. Latch unit has latch that engages striker, ratchet that engages latch and first cinching lever that displaces latch from a half-latched position to a full-latched position. Latch unit is attached to an end portion of a vehicle door. Power unit includes motor, cable drum, deceleration mechanism and closed-type housing that houses them. Operational noise at 300 mm right above the housing of power unit is 42.2 to 40.9 dB at a supply voltage to the motor of 9V, 47.5 to 43.9 dB at a supply voltage of 12V, and 49.7 to 46.5 dB at a supply voltage of 16 V. Deceleration mechanism includes a worm gear and a helical gear.
