  • a locking system with a rotatable adjusting element which can be manually moved into two switching positions.
  • the actuating element interacts with a spring element, the spring element enabling the actuating element to be locked in two switching positions.
  • Different embodiments of spring elements are disclosed, which consist of a spring element and a form-fitting Allow engagement of the actuating element with the spring element to secure the position of the actuating element.
  • the DE 195 36 648 A1 shows a motor vehicle door lock with a child safety system and a child safety button.
  • the child safety button is rotatably arranged in a bearing recess of the motor vehicle door lock.
  • the child safety button has an eccentrically rotating control cam which works on a coupling element. Depending on the position of the control cam, the associated actuating lever mechanism for internal actuation is interrupted or mechanically connected.
  • the DE 10 2014 114 347 A1 discloses a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and pawl, furthermore with an actuating lever mechanism working on the pawl and with a child safety device with a child safety lever which is spring-loaded.
  • the motor vehicle door lock is characterized in that the child safety lever and the spring are designed as a one-piece structural unit.
  • the spring element formed in one piece on the actuating element is designed in such a way that an increased pressure acts on the actuating element in an intermediate position between the two locking positions, so that the actuating element is pivoted into the locking position.
  • the adjusting elements known from the prior art have basically proven themselves, but can then reach their limits if, for example, the motor vehicle lock with means for automatically resetting the function inserted by means of the adjusting element have. In this case, the adjusting element must also be actuated and the corresponding spring force or counterforce from the adjusting element must be overcome. This is where the invention comes in.
  • the object of the invention is to provide an improved motor vehicle lock.
  • a motor vehicle lock having a locking mechanism with a rotary latch and at least one pawl, the rotary latch being latchable by means of the pawl in at least one latching position, an adjusting device with an adjusting element and an on the actuating element acting on the spring element, wherein the actuating element can be positioned by means of the spring element and wherein the actuating element can be reset by means of the spring element after actuation of the actuating element.
  • the structure of the motor vehicle lock according to the invention now makes it possible to provide an actuating element with which, on the one hand, a high level of functionality can be ensured and, at the same time, the reset of the inserted function is made possible with minimal expenditure of energy.
  • actuating element with which, on the one hand, a high level of functionality can be ensured and, at the same time, the reset of the inserted function is made possible with minimal expenditure of energy.
  • sufficient forces must be made available via the electric drive, which also enable the inserted function to be reset at any point in time and with a high degree of security.
  • the reset must be performed can be guaranteed in the starting position. If in this case it is also necessary to overcome a spring force of an actuating element, then additional loads are placed on the electric drive.
  • actuating means moves, for example, a lever chain and / or interrupts an actuating lever chain in such a way that, for example, a child safety device can be inserted.
  • a child safety device is present when an internal operating lever and in particular the operating lever chain of the internal operating lever does not lead to an unlocking of the locking mechanism.
  • the motor vehicle lock can be unlocked by means of an external actuating lever and thus the door can be opened, actuation of the internal actuating lever, however, does not lead to the motor vehicle lock being opened.
  • a function or a functional state is set in the motor vehicle lock that is user-defined and remains in the functional state after it has been inserted.
  • the adjusting element is reset by means of the spring element, that is to say it is returned to the starting position after it has been deflected, the functional state that was set by means of the adjusting element is retained.
  • This offers the advantage that when the child safety device is reset, that is to say, for example, when the child safety device is disengaged, which is reset electrically, for example, the adjusting element does not have to be returned to the starting position. This increases the ease of movement when resetting and relieves an electric drive, for example.
  • a functional state can be set by means of the actuating element, which can then be interpreted again manually and / or electrically, then there is also the possibility of interpreting the functional state by actuating the actuating element again.
  • an actuating chain to be actuated by means of the actuating element, which operates, for example, according to a ballpoint pen principle, so that the functional state is inserted when the actuating element is actuated for the first time, the functional state after a second actuation of the actuating element can be interpreted again.
  • the actuation chain can, for example, have a heart curve which, with the aid of springs, can insert or interpret different functional states.
  • the adjusting element can be brought into engagement with a control contour.
  • the adjusting element is accommodated in the motor vehicle lock in a pivotable manner, for example by means of a switch nut into which a tool can be inserted.
  • the actuating element engages in a control contour which, on the one hand, enables the pivoting path of the actuating element to be limited and, on the other hand, can exert a spring force on the actuating element that enables the actuating element to be reset.
  • the control contour thus serves to limit the pivoting angle of the actuating element and, on the other hand, the actuating element can be reset by means of the control contour itself.
  • the control contour is preferably introduced into a housing of the motor vehicle lock, preferably formed in one piece with the housing of the motor vehicle lock, so that a minimal number of components are required to implement the construction of the motor vehicle lock according to the invention.
  • the control contour can be designed, for example, as a pitch circle trajectory with a stop at the start and end.
  • the control contour can provide at least one positive locking position for the actuating element.
  • the adjusting element is preferably at least in the area of the engagement contour of the Tool for actuating the actuating element constructed axially symmetrically and stored in an opening of the housing.
  • a further bearing point can be provided in the motor vehicle lock, in which the adjusting element can be stored, guided and / or retained.
  • the adjusting element can be actuated through the housing opening, with a hexagon, for example, being insertable into a cooperating opening in the adjusting element.
  • the adjusting element has a base body, the base body having a bearing point and at least one recess.
  • the base body has a bearing point that can be received, for example, in a bearing point of the housing.
  • the actuating element is usually designed with a small number of actuations over the service life, the use of, for example, a separate bearing sleeve can be advantageous, for example, when smooth actuation of the actuating element and / or low-noise actuation of the actuating element is required.
  • a plain bearing or a separate bearing means such as a plastic guide for the adjusting element, is conceivable.
  • the actuating element itself or the base body of the actuating element is preferably received directly in the lock housing, that is to say the housing cover or the housing base.
  • the recess arranged in the adjusting element is used to pivot the adjusting element and thus to actuate it.
  • a slot-shaped opening in the actuating element is preferably conceivable, since a slot-shaped recess offers the advantage that the actuating element can be actuated by means of a wrench or a screwdriver. Such aids are mostly available.
  • the base body has an extension, the extension extending from the base body to the control contour, and if the extension is in engagement with the control contour, then there is a further embodiment variant of the invention.
  • An extension on the base body can be advantageous because the extension with the control contour enables angular movements of the actuating element that are defined jointly.
  • the base body is by means of the extension of the actuating element can also be arranged at a distance from the control contour in the motor vehicle lock. This increases the flexibility in the design, since not all installation spaces are available directly on the base body of the actuating element for the formation of a control contour.
  • the extension can also be used to access the component in the motor vehicle that is to be actuated by means of the actuating element.
  • the extension then not only serves to limit or guide the actuating element, but also serves at the same time as an actuating element for inserting the desired functional state. Continuous abutment of the extension on the control contour ensures that the adjusting element can be additionally guided, which in turn ensures increased functional reliability.
  • the extension is formed in one piece with the base body of the actuating element.
  • the adjusting element is preferably made of plastic, and more preferably made of a plastic produced by means of an injection molding process.
  • the one-piece construction of the adjusting element is thus possible in an advantageous manner and in one operation.
  • This also facilitates the assembly of the actuating element, since in this case only a single component is required to form an actuating element arranged pivotably in the motor vehicle lock.
  • the adjusting element interacts advantageously with the housing, the motor vehicle lock housing also being made of plastic.
  • the material pairing plastic of the adjusting element and plastic of the housing results on the one hand in favorable manufacturing costs and on the other hand a high degree of structural freedom in the formation of the adjusting element or the mounting and guidance for the adjusting element can be guaranteed.
  • the extension forms a spring element for the actuating element.
  • the extension can serve as an additional guide for the adjusting element, secondly, an angle limitation can be made by means of the extension, and thirdly, by means of the extension the functional state can be inserted in the motor vehicle lock and fourthly, the extension itself can form the spring element for resetting the actuating element.
  • the extension arranged on the actuating element can consequently take on essential functions for the actuating element and the function of the actuating element, whereby the insertion of a functional state in the motor vehicle lock can be ensured with minimal structural effort and the smallest possible number of components.
  • the extension as a spring element and an extension formed on the base body can form the spring element for resetting the adjusting element.
  • the spring constant can advantageously be set via the thickness, that is to say the width of the extension over the extension of the actuating element. Depending on the desired moment, it is conceivable to vary the thickness of the extension and thus to adjust the spring force acting on the adjusting element. If the extension has an essentially uniform thickness, the extension in the area of the connection to the base body can have a greater thickness, so that sufficient long-term stability or permanent elasticity of the extension on the actuating element or base body can be ensured.
  • the extension can be brought into engagement with the control contour in a form-fitting manner, at least in some areas, so that in particular a stop for the control element can be formed.
  • a form-fitting engagement of the extension in the control contour can be advantageous, for example, in the starting position of the adjusting element, for example in order to be able to give the operator of the adjusting element haptic feedback that the adjusting element is in the starting position.
  • the extension can interlock positively in the control contour and thus indicate that the final position of the actuating element has been safely reached or, in turn, provide the operator with haptic feedback that the final position of the actuating element has been reached.
  • a functional state in the motor vehicle lock can be set in the simplest way, the operator only having to set the functional state without having to return the adjusting element to the starting position. This enables simple operation and, at the same time, an electrical reset of the functional state, for example, can be achieved with less energy consumption.
  • Figure 1 a basic illustration of an actuating element in a motor vehicle lock, only the components essential to explain the invention being reproduced.
  • FIG. 1 components of a motor vehicle lock are reproduced for the insertion of a functional state.
  • the actuating element 1 is shown in a top view of a switch nut 5, which extends through an opening 6 of the housing 2.
  • the housing 2 is only shown in certain areas, so that the extension 8 formed on a base body 7 and the interaction of the extension 8 with the control contour 3 can be seen.
  • the starting position A of the actuating element in which the actuating element 1 is in the non-actuated state.
  • the control element 1 When actuated via the shift nut 5 and in particular the recess 9, the operator can pivot the adjusting element 1 in the direction of the arrow P clockwise. If the actuating element 1 is pivoted in the direction of the arrow P, the extension 8 reaches the actuation position B, the extension 8 engaging with the actuation lever 4 and in particular with an actuation section 10 of the actuation lever 4. If the adjusting element 1 is moved further in the direction of the arrow P, the actuating lever 4 is pivoted about its pivot axis S in the direction of the arrow P1.
  • the extension 8 reaches its end position E, the extension 8 coming into engagement with a stop 11.
  • the actuating lever 4 has then been pivoted so far that the functional state to be inserted by means of the actuating element 1 is reached.
  • the end position E of the extension 8 is shown in principle with the dashed line 8 '.
  • a restoring force F builds up, which is designed in such a way that the adjusting element 1 is automatically returned to the starting position A.
  • the actuating lever which is pivotably accommodated in the motor vehicle lock, is transferred into its functional position and can, for example, be returned to the position shown in FIG. 2 by means of a manual and / or electrical intervention (not shown) Figure 1 position shown are returned.
  • the actuating lever 4 can be reset by repeatedly actuating the shift nut 5.
  • the inventive construction of the actuating element 1 and in particular the connection of the extension 8 to the base body 7 enables the construction of an actuating element with the smallest possible number of components, so that a structurally advantageous design variant of a motor vehicle lock can be provided.
