  • the transmission lever is pivoted during normal operation of the release lever. Normal operation is understood to mean the intentional opening of a motor vehicle door. A via a spring connected to the transmission lever mass moment of inertia is pivoted simultaneously with the transmission lever.
  • the release lever is movable and actuates the locking mechanism indirectly or directly, so that the motor vehicle door lock is unlocked and opened.
  • Fast opening means an unintentional opening in which high acceleration forces act on the outside handle, for example in an accident situation such as a crash.
  • the release lever is blocked by the inertia element, wherein the inertia element in contrast to the transmission lever remains in its position due to its high mass.
  • the transmission lever is pivoted.

  • the transmission lever can be omitted with a favorable arrangement of the components.
  • the inertia element is rotatably mounted on a movably mounted transmission lever.
  • the inertia element and the transmission lever are mounted on the same pivot.
  • the inertia element and the transmission lever have the same axis of rotation. It is advantageous that the same forces act on both levers. Another advantage is the interaction via a spring.

  • the actuating lever is rotatably mounted on an axle. The operating lever can pivot or turn.
  • the actuating lever has at its one bearing point opposite end of an extension or a hingedly connected member, wherein the extension projects beyond a bearing point of the inertia element.
  • the bearing point of the mass moment of inertia lies on the Operating lever, preferably the extension or a hinged member.
  • a transmission lever At the extension of a transmission lever is attached.
  • the transmission lever interacts with a locking lever.
  • the transmission lever is mounted on a rotation axis which is parallel to the common axis of rotation of the mass moment of inertia and the actuating lever.
  • the transmission lever can actuate a locking lever, preferably a central locking lever, wherein a lock of the motor vehicle door lock is inserted. Space-related ways in the vehicle door lock are solved via the use of a transmission lever.
  • the transmission lever actuates the locking lever.
  • a locking lever is a central locking lever.
  • the locking lever blocks the outside operation.
  • the door can not be opened from the outside when locked by the locking lever.
  • the extension can cooperate with a microswitch, wherein in a deflection of the actuating lever of the microswitch is actuated.

  • the lock is also able to lock the ratchet when the battery is no longer functional, for example in an accident situation. It is conceivable, for example, to provide the switching means with a Glühdrahtomme, wherein the switching means after a predetermined time, for example, two seconds, out of function. The vehicle door can then be unlocked.
  • the power supply of the motor vehicle door lock can also be done via the normal electrical system, in particular from the starter battery.
  • the extension is durable by means of a positioning means, in particular a spring and / or a damping means in its position.
  • the extension is held by a positioning in an end position. An unwanted deflection of the extension is prevented.
