Definitions

  • the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with an actuating lever chain and with at least one electric motor drive for the actuating lever chain, the actuating lever chain having at least one child safety lever, one anti-theft lever and one central locking lever.

  • Different functional positions of the motor vehicle lock can be realized and implemented via the actuating lever chain and the at least one electric motor drive working on it.
  • the functional position "Child lock on” corresponds to the fact that an associated motor vehicle door (usually one or both of the rear motor vehicle side doors) is locked from the inside. That is, the motor vehicle door in question can be opened from Do not open from the inside, but opening from the outside is possible because there is no corresponding external locking mechanism.
  • the actuating lever chain In the "locked” or “centrally locked” functional position, the actuating lever chain is set up in such a way that, in contrast, an external locking is implemented, but the motor vehicle door in question can still be opened from the inside and unchanged, because in this case an internal locking is not reflected.
  • the functional position “anti-theft” corresponds to the relevant motor vehicle door being locked both on the inside and on the outside. As a result, the motor vehicle door cannot be opened, neither from the inside nor from the outside, even if the window is broken and in the event of an attempted theft.
  • the “locked” or “secured” state of the associated component of the actuating lever chain is usually implemented and implemented in practice in such a way that an associated clutch lever ensures a mechanical interruption. Consequently, the locking mechanism cannot be opened with the (open) actuating lever chain. If, on the other hand, the actuating lever chain or the corresponding part of the actuating lever chain is in the “unlocked” or “unlocked” state, this includes an engaged position of the clutch lever in question. In this case, the actuating lever chain is closed, so that in the unlocked state and, for example, when the actuating lever chain is acted upon manually or by a motor, the locking mechanism can be opened by a release lever lifting the pawl away from its engagement with the rotary latch.
  • the invention is based on the technical problem of further developing such a motor vehicle lock and in particular a motor vehicle door lock in such a way that the structural and monetary outlay is reduced and an embodiment with the lowest possible weight compared to previous designs is observed.
  • the invention proposes in a generic motor vehicle lock and in particular motor vehicle door latch that the electric motor drive as the only drive for Realization of a central locking, a child safety device and an anti-theft device is set up and trained.

  • a locking clutch lever is additionally provided.
  • the locking clutch lever is also and advantageously mounted on the same axis as the child safety lever, anti-theft lever and central locking lever.
  • the lockup clutch lever and central locking lever are typically coupled to each other via a spring. In this way, the central locking lever and the locking clutch lever can perform a mutual relative movement to one another, but are nevertheless each moved back into a specific relative position after a deflection by the spring.
  • the locking clutch lever has an actuating pin for acting on the anti-theft lever.
  • the lockup clutch lever is usually equipped with two control arms. The two control arms engage alternately or together in a recess in the drive. In addition to the two control arms, another control arm of the central locking lever also engages in the relevant recess of the drive.
  • the recess in question is generally found on or in a gear wheel of the drive.
  • the gear wheel is usually the gear wheel on the output side.
  • the electric motor drive mostly has a driven worm, which interacts with a driven gear wheel or first gear wheel.
  • This drive gear wheel or first gear wheel is also and advantageously equipped with an embedded spring, which as a whole returns the electromotive drive to its starting position after it has been acted upon or has been adjusted. This typically applies to both rotational movements that can be implemented using the output gear, i. H. both clockwise and counterclockwise.

  • the electric motor drive for the realization of the central locking, the child safety device and the anti-theft device acts as the only drive and expressly no further second or even more drives are provided. Rather, the sophisticated further kinematics ensure that the individual functional positions can be separated from one another without any problems.
  • the paraxial is predominantly responsible for storing the child safety lever, the anti-theft lever and the central insurance lever in conjunction with the locking clutch lever.
  • the concept of the central locking lever also includes and covers embodiments that do not necessarily have a central locking system for all motor vehicle locks in a motor vehicle or are linked thereto. Rather, the central locking lever can, quite fundamentally, also be a locking lever that is implemented singularly. Since there are usually several motor vehicle locks in a motor vehicle and these are moved centrally to their “unlocked/locked” position, the locking lever in question is typically designed as a central locking lever.
