Definitions

  • the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of rotary latch and pawl as locking components, furthermore with a closing / opening device with at least one drive and a lever chain that can be acted upon by this, and with a drive pawl following the lever chain for Drive of the associated locking part.

  • closing devices for motor vehicle tailgate locks or Motor vehicle side door locks are also used.
  • the relevant tailgate or motor vehicle side door is transferred from the manually reached pre-locking position with the aid of the drive into a main locking position or main locking position. If during this process it happens that, for example, clothing or - worse still - fingers of an operator are jammed in the door gap, a kind of emergency opening is required or the associated closing process must be interrupted. In the case of such an emergency interruption, the procedure is generally such that the drive pawl for driving the associated locking component is lifted immediately from its engagement with the catch in the event of the closing movement already described above.
  • the generic prior art according to DE 10 2011 012 656 A1 provides in this context that the additionally provided opening drive including opening transmission lever to interrupt the closing function is set up.

  • This allows the rotary latch to open with the assistance of a spring and release a locking bolt that was previously caught. If such an opening movement is interrupted, this can take place again in that the drive pawl is lifted from its engagement with the locking pawl in the example.
  • the problem of being able to implement an emergency interruption regularly arises primarily with closing devices and a corresponding closing process.
  • a generic motor vehicle lock within the scope of the invention is characterized in that the lever chain is equipped with an optionally closable and openable separation point to interrupt a closing / opening movement, while the drive pawl remains in engagement with the locking component.

  • the first actuating lever is generally acted upon indirectly or directly with the aid of the drive.

  • the overall design can be such that the separation point between the two actuating levers in the example is positioned in such a way that the coupling element usually provided in the area of the separation point can be acted upon easily with the aid of the ejector lever, taking into account a structurally simple configuration.
