  • the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and a pawl, and with a release lever for acting on the pawl and for opening the locking mechanism.
  • motor vehicle lock is to be understood broadly in this case and applies not only to motor vehicle door locks, but also, for example, to motor vehicle locks in connection with the locking of seats, flaps, etc.
  • motor vehicle locks are nowadays and increasingly operated by electric motors. This means that special comfort applications can be implemented and the operating forces are low.
  • a generic motor vehicle lock and in particular a motor vehicle door lock is characterized in the context of the invention in that the release lever is designed in two parts with a pawl release lever acting on the pawl and an actuation release lever that interacts with, for example, an actuating lever and / or drive, both of which Lever are either coupled to one another or decoupled from one another via a coupling member that can be pivoted about an axis.
  • the release lever is composed of the pawl release lever and the confirmation release lever. While the pawl release lever primarily ensures that the pawl can be lifted from its latching engagement with the rotary latch when the locking mechanism is closed, a pivoting movement is usually entered into the release lever as such via the actuation release lever. In terms of their basic concept, both levers are designed to be functionally and mechanically separate.
  • the two levers can now either be coupled to one another or decoupled from one another. If the two levers are coupled to one another, there is a rotationally fixed connection, so that an action on the actuation release lever is and can also be transmitted to the pawl release lever, which in turn then lifts the pawl from its engagement with the rotary latch.
  • the rotary latch can open with spring support and release an associated and previously caught locking bolt.
  • the door equipped with the relevant motor vehicle lock can be opened easily.
  • both levers are separated from each other, so that if necessary, the pawl can be returned to its starting position using a pawl spring, for example, and can fall into the rotary latch.
  • the pawl release lever moves with the pawl and performs a relative movement relative to the actuation release lever.
  • the coupling member is mounted on the actuation release lever so that it can pivot about its axis.
  • the design is such that the coupling member interacts with a stop on the pawl release lever. If the coupling member is therefore in its “engaged” state, the coupling member, which is pivotally mounted about its axis on the actuation release lever, ensures that over the
  • both levers are coupled to one another and in the second case, they are decoupled from one another.
  • a manipulation element In order to be able to pivot the coupling member between the two described functional positions “engaged” and “disengaged”, a manipulation element is usually provided.
  • the manipulation element can be acted upon manually, for example.
  • Such a manual action on the manipulation element is particularly easy and functional if the manipulation element is mounted in, for example, a housing of the motor vehicle lock and in particular the motor vehicle door lock, so that the manipulation element can be manually acted upon from the outside by an operator and pivoted accordingly.
  • the manipulation element may advantageously be an actuation nut, a swivel nut or a comparable manipulation element. Since this is rotatably mounted in the housing of the motor vehicle lock and in particular the motor vehicle door lock, a pivoting movement of the manipulation element can be initiated by an operator via a slot provided, for example, in an actuation nut using a screwdriver, a key, etc.
  • the manipulation element in question is accessible from the outside and may otherwise be hidden under a cap, strip, outside door handle, cover, etc.
  • the manipulation element is generally designed with the interposition of a deflection lever and works on the coupling member using the deflection lever.
  • the deflection lever is generally mounted on the same axis as an electric motor drive for the locking mechanism.
  • the electric motor drive in question is generally used to open the locking mechanism electrically and acts on the actuation release lever for this purpose.
  • the electric motor drive usually has an actuating element that works on the release lever.
  • the coupling member has assumed its “coupled” state
  • the actuation of the actuation release lever via the engaged coupling member results in the pawl release lever, which is mounted on the same axis as the actuation release lever, being taken along.
  • the pawl release lever the pawl can then be lifted from its locking engagement with the rotary latch. In the “disengaged” state, however, an empty movement occurs.
  • the deflection lever is generally designed with a manipulation arm and a coupling arm. This is preferably done in such a way that the manipulation element works on the manipulation arm and the coupling arm works on the coupling member.
  • a pivoting movement of the manipulation element results in the coupling member being either “engaged” or “disengaged” in its functional position.
  • the manipulation element ensures that the coupling member, which is in the “engaged” state, is transferred to its “disengaged” functional position, so that in the event of a blockage of the release lever and/or the electric motor drive, the pawl release lever and the actuation release lever are mechanically separated from one another.
  • the manipulation element is advantageously stored in a housing of the motor vehicle lock.
  • the manipulation element is generally designed to be rotatable about an axis perpendicular to the axis of the release lever. Since the manipulation element rotates about an axis that is oriented perpendicular to the axis of the release lever, the deflection lever is generally required.
  • the deflection lever is mounted on the same axis as the electric motor drive. The axis of the electromotive
  • the drive generally runs parallel to the axis of the release lever.
  • the rotational movement of the manipulation element about its axis initiated by an operator is transferred with the help of the deflection lever into a corresponding pivoting movement of the deflection lever in a plane that runs parallel to the plane of the release lever, so that the deflection lever, which is oriented at the same level as the release lever, is used for the corresponding action on the coupling member ensures and can also provide, which in turn is mounted on the actuation release lever so that it can pivot about its axis.
  • the coupling member As soon as the coupling member is no longer acted upon by the deflection lever and consequently also the manipulation element, the coupling member generally returns to its starting position “coupled” with spring support.
  • the manipulation element and possibly the deflection lever also have an associated return spring.
  • This return spring can be designed as a separate spring element or as a plastic lip on the housing of the motor vehicle lock, which is typically made of plastic.
  • the coupling member is generally designed with a separate spring, which is generally designed as a leg spring.
  • One leg of the leg spring is mounted in a stationary manner, while the other leg rests on the coupling member and is acted upon when the coupling member transitions from its initial “engaged” position to the “disengaged” position.
  • the leg resting on the coupling member can return the coupling member to its initial position “coupled” using the manipulation element via the intermediate deflection lever after the loading of the coupling member has ceased.
  • the action on the manipulation element results in the two components of the two-part release lever, i.e. the actuation release lever and the pawl release lever, being mechanically separated from one another.
  • the coupling member that couples the two levers together in normal operation is pivoted from its “engaged” position to the “disengaged” position.
  • both levers can perform a relative movement against each other.
  • This relative movement can be initiated or supported, for example, by a pawl spring assigned to the pawl.
  • the pawl returns to its basic position with the help of the pawl spring in order to then be able to rust the rotary latch with the locking bolt caught on the side of the rotary latch. All of this is particularly easy to realize and implement in terms of technology and design. This is where the main advantages can be seen.
