- the electric motor drive can be used, by way of example and not restrictively, to electrically open a locking mechanism consisting of a rotary latch and a pawl.
- the electromotive Drive but also apply an exhibitor as a component or associated unit with the required electrical energy.
- the electromotive drive can—as described—be used to the effect that with its help an actuating lever chain is acted upon, for example, it is transferred from the assumed “locked” state to the “unlocked” functional state.
- the emergency energy source inside the motor vehicle lock housing can be replaced according to the invention at regular intervals or its functionality can be checked easily.
- the emergency energy source is arranged according to the invention in the area of the inlet opening for the locking mechanism, which essentially consists of a rotary latch and a pawl.
- the invention is based on the knowledge that when the motor vehicle door belonging to the motor vehicle lock is open, the inlet opening in question for the locking mechanism is directly accessible.
- the emergency energy source can also be checked and replaced without any problems and if necessary.
- the emergency energy source usually has a detachable cover.
- the cover can advantageously be arranged in a recess for accommodating a lock holder which interacts with the ratchet. So as soon as the motor vehicle door is opened and the lock holder releases the depression in question, the emergency energy source is accessible via the detachable cover. This means that the emergency energy source can be removed and replaced if necessary, but also checked and even repaired if necessary.
- the procedure is usually such that the cover is equipped with guide tongues on both sides. This ensures that the cover is properly held in the area of the inlet mouth.
- the coverage is usually considered a sliding rule designed, can therefore be opened and closed by a sliding movement.
- the compartment for accommodating the emergency energy source is generally part of a housing body.
- the lock housing is regularly constructed in at least two parts from said housing body and, in addition, a housing cover.
