A vehicle door latch device has actuator and engagement assemblies of a front- or rear-tooth engagement system. The engagement assembly includes a body, a pivotable latch engaging a striker, a pivotable ratchet engaging the latch, and an input lever pivotably supported to the body to transmit its releasing operation to the ratchet. The actuator assembly includes a housing fixed to the body and an output lever transmitting power to the input lever. The housing includes a body covering portion selectively fixed to the engagement assembly of the front-tooth engagement system and that of the rear-tooth engagement system. The output lever is pivotably supported in the housing with an output portion moving vertically based on its releasing operation. The input lever has an input portion that crosses the output portion, and is released by abutting the output portion with the input portion based on the output lever releasing operation.

The present disclosure relates to an opening/closing assistance mechanism for assisting the opening/closing of a latch for an opening. The opening/closing assistance mechanism includes an electric actuator configured to control a closing and an opening of the latch. The electric actuator includes a reducer which includes a drive device configured to perform a displacement stroke which further includes a first stroke portion for the opening of the latch and a second stroke portion for closing the latch. The reducer has a first reduction ratio on the first stroke portion and a second reduction ratio on the second stroke portion. The first reduction ratio is different from, and can be lower than, the second reduction ratio.

The disclosure relates to an overload coupling for an actuating mechanism for actuating a charging, fueling, or service flap on a charging, fueling, or service compartment that is or can be received on or in a body component of a vehicle. The overload coupling includes a drive-side coupling element and an output-side coupling element and, in an engaged state by means of a form-fit and/or force-fit lock, transfer a torque and thus a drive movement from the drive-side coupling element to the output-side coupling element. When a critical torque to be transferred is reached or exceeded in the event of an overload, to lift the form-fit and/or force-fit lock between the drive-side coupling element and the output-side coupling element.
