  • the known motor vehicle lock ( WO 2009/040074 A1 ), from which the invention proceeds, is equipped with the usual closing elements latch and pawl.
  • the motor vehicle lock further has a lock mechanism which can be brought into various functional states such as “unlocked”, “locked”, “theft-proof” and “child-proof”.
  • the motor vehicle lock further comprises an internal operating lever, which is coupled in the mounted state with a door inner handle, and an external operating lever, which is coupled in the assembled state with an outside door handle on.

  • the two rocker arms extend in a first approximation of the rocker axis, starting in opposite directions. It does not necessarily matter that the two rocker arms run straight. Furthermore, it is not important that the two rocker arms have the same length.
  • a transmission rocker in the present sense is an elongated structure which translates a drive-side adjustment on the drive-side rocker arm into an output-side adjustment on the clutch element-side rocker arm.
  • the advantages of the invention can be fully exploited with the variants according to claim 4. This is especially true in the design of the coupling element as a resilient bendable wire or strip, as this results in a very simple and at the same time flexible structural structure.

Also in this respect results in a particularly compact arrangement. It is also conceivable that the coupling element 7 is aligned with its elongate portion 18 only with respect to one of the two lever axes 14, 15 in the above manner. In this case, the corresponding lever axes 14, 15 are not identical.

This can basically a separate spring arrangement be waived. Alternatively or additionally, however, it may be provided that the spring bias of the coupling element 7 on the coupling element side rocker arm 13 in any case also goes back to a spring arrangement coupled to the coupling element 7.
