Definitions

  • the invention relates to a motor vehicle lock having a locking mechanism, with a catch and at least one pawl, a release lever, by means of the release lever, the pawl is disengaged from the catch, a memory lever function, wherein by means of the memory lever function actuated to disengage the catch release lever in a actuated position is fixable.
  • the motor vehicle locks used in the flaps, doors, sliding doors or hoods are equipped with a variety of functions. One of these functions is that even in the case of opening a locking mechanism in a motor vehicle lock reclosing or incomplete opening is prevented.
  • the lock is a tailgate lock
  • the locking mechanism remains in the engagement area of the lock holder, since the flap is loaded with a high load, especially a snow load, is acted upon.
  • the catch engaged with the lock holder can not completely move out of the engagement area of the pawl or swing out of the engagement area of the pawl, so that there is the risk that the pawl engages again with the catch.
  • the snow load function can be integrated in a motor vehicle lock.
  • the once disengaged pawl during the opening operation is held in a position in which the pawl can not get back into engagement with the rotary latch.
  • the disengagement holding the pawl is referred to as storage lever function or snow load function.
  • a motor vehicle lock and in particular a tailgate lock has become known, which is equipped with a memory lever function.
  • a release lever is provided in which a Mitauerkontur is provided, with which the pawl is disengaged from the catch can be brought. It is in the known motor vehicle lock to an electrically operated lock, wherein the release lever is actuated via a cam. Release lever and pawl are pivotally mounted on a common axis, so that the release lever can pivot the pawl on the Mitêt noirkontur.
  • a memory lever formed on the housing of the motor vehicle lock which cooperates with a projection of the release lever, so that the release lever is held in its deflected position, the open position, in the deflected or open position. That is, after a pivoting of the release lever and thus a disengagement of the pawl with the catch of the release lever is fixed in position or held by the interaction of the jump on the release lever with the storage lever in position. At the same time, the detent pawl is held in a position by means of the driver contour, which prevents re-engagement with the rotary latch.
  • the memory function prevents the pawl from coming into engagement with the main catch or the catch of the catch. Only when the catch has been fully opened, a triggering contour on the catch with the storage lever engages and releases the release lever, whereby the release lever and the pawl can be moved back into their original position or engage and engage the catch. That is, the release lever and the pawl are applied to the rotary latch. The concern takes place by means of a spring preload.
  • Another motor vehicle lock has become known from DE 103 61 168 A1.
  • the motor vehicle lock described also comprises a memory lever function, wherein a spring arm cooperates with a latching connection element with a latching connection counter element in such a way that a latching pawl can be held out of engagement with the rotary latch.
  • the latching connection element is formed on the drive arm and cooperates with a contour, the latching connection counter-element, on the catch.
  • Detent connection element and locking connection counter element are designed such that they engage when opening the locking mechanism and lead over the main locking position and a pre-locking position away the pawl. Only in the fully opened state, the latching connection element and the locking connection counter-element come out of engagement again. In the fully open state locking latching element and latching counter-element are thus released from each other and the pawl is spring biased to the rotary latch.
  • a problem that may arise in motor vehicle locks with a memory function is that when closing the locking mechanism, the pawl and / or the release lever are guided by the catch and can learn depending on the speed of actuation of the catch when closing by the catch a pulse .
  • trigger and / or pawl are applied to the catch and are spring biased guided by the catch. If the catch is accelerated too much during closing, this can lead to the pawl and / or the release lever being subjected to a pulse or force in such a way that the catch and / or the release lever can enter the storage lever function. In this case closing of the locking mechanism by the memory lever function would be prevented.
  • the object of the invention is to provide an improved motor vehicle lock.
  • it is an object of the invention to increase the reliability of motor vehicle locks and to ensure an intervention of the locking functions at any time with great certainty.
  • it is It is an object of the invention to provide a structurally simple and inexpensive motor vehicle lock.

  • a disengaged for disengaging the catch release lever is fixed in an actuated position and wherein the release lever is only partially feasible through the catch. Due to the fact that the release lever is only partially feasible through the rotary latch, the possibility is now created that the release lever is held securely to each position of the rotary latch in an abutment position on the rotary latch. Unintentional movement of the release lever, for example by rapid actuation by means of the rotary latch, can thus be purposefully controlled, that is, the release lever is guided only in the area by means of the rotary latch, which is necessary for the function of the release lever.
  • the motor vehicle lock according to the invention has a locking mechanism, with a rotary latch and at least one pawl.
  • Rotary latch and pawl act in such a way that the pawl fixes the catch in a position in which the catch has been moved by means of, for example, a lock holder.

  • the motor vehicle lock on a release lever by means of the release lever, the pawl or pawls can be disengaged from the catch.
  • the release lever engages the pawl and moves the pawl in a region which is outside a pivoting range of the rotary latch.
  • the rotary latch is thus able to reach by means of a spring preload and / or a sealing pressure of the flap or door in an open position. In the opening positions, the door or flap can then be fully opened.
  • the pawl is held by means of the release lever out of engagement with the rotary latch. This may be necessary in particular if, as described above, a snow load acts on a tailgate, for example, and the flap can not be completely opened. An operator of the motor vehicle is then able to open the flap, even though the pawl is in a position to be in a position, with respect to the angle of rotation of the catch, to engage, for example, a pre-catch of the catch.

This can be For example, done by an operator manually opens the tailgate. In a fully open position of the catch, the memory lever function is then deactivated, so that the pawl and the release lever get back into contact with the catch.
  • the release lever is only partially guided through the rotary latch.
  • the release lever is only partially guided through the rotary latch when the body is closed. This is in particular to the advantage that the release lever can not be transferred by the closing movement of the rotary latch in an undefined position and in particular not in a storage lifting position.
