Definitions

  • the present invention relates to a motor vehicle door lock with a locking mechanism with a catch and a pawl.
  • the closure further includes a trigger lever, a blocking lever and two operating levers.
  • the blocking lever prevents rotation of the trigger lever and thus opening of the ratchet when at least one of the operating levers is operated at an operating speed exceeding a predetermined threshold. This occurs, for example, in an accident, especially in a side impact.
  • the door lock cooperates with a locking bolt or equivalent with a striker.
  • the door lock is arranged in the motor vehicle door and the locking bolt on the vehicle body, but also a reverse arrangement is possible.
  • the rotary latch rotates about its axis of rotation, so that the locking pin is caught in the rotary latch and thus opening of the motor vehicle door is prevented.
  • the pawl cooperates with the catch by preventing rotation of the catch and thus the release of the striker.
  • door handle or "handle” means any handle on the door of a motor vehicle the operation of which actuates an associated operating lever of the motor vehicle closure.
  • a side impact strong accelerations act on the motor vehicle.
  • a door handle has a certain inertia, so that the side impact can lead to an actuation of the door handle.
  • the operation is jerky with an operating speed that exceeds the operating speed by a human significantly. This is also the case when the door handle hangs on an object Based on the operating speed of the door handle and thus the associated operating lever can thus distinguish whether the locking is to be disabled, so effectively prevents rotation of the catch in its release position for the locking pin shall be.
  • the threshold for this distinction is an operating speed limit, which is defined, for example, as the limit angular speed of an actuating lever.
  • This functionality enables a motor vehicle door lock according to the independent claim 1.
  • Advantageous embodiments are specified in the dependent claims. From the publication DE 10 2011 010 815 A1 is a motor vehicle door lock with a locking mechanism with a catch and a pawl, acting on the pawl trigger lever, acting on the trigger lever blocking lever, and with a first actuating lever which acts on the trigger lever and a first leg spring on the blocking lever known.
  • the present invention relates to a motor vehicle door lock with a ratchet with a catch and a pawl, acting on the pawl release lever, acting on the trigger lever blocking lever, a first actuating lever which acts on the trigger lever and a first leg spring on the blocking lever, and a second operating lever, which acts on the release lever and a second leg spring on the blocking lever.
  • the pawl prevents, as usual in motor vehicle door locks and already described above, a rotation of the rotary latch about its axis of rotation, through which a captive locking bolt is released and can open the vehicle door. This is what the Pawl into the catch. To trigger the locking the release lever acts on the pawl.
  • a rotation of the release lever about its axis of rotation causes a rotation of the pawl about its axis of rotation, so that the pawl disengages from the catch.
  • the rotation of the release lever about its axis of rotation is determined by the rotation causes at least one actuating lever about its axis of rotation.
  • the rotation of an actuating lever about its axis of rotation is caused by the operation of an associated door handle.
  • axis of rotation means a virtual line perpendicular to a plane of rotation in which a point of a component moves as the component is rotated about the axis of rotation.
  • axis of rotation may also refer to the actual physical axis about which a component is rotated, for example in the form of a pin.
  • a leg spring is a lower form of the helical spring with a typically cylindrical spring body wound essentially cylindrical body with two lever-like legs.
  • the main body has a (virtual) axis, which lies in the middle of the winding, that is, defines a central axis of the leg spring. The force is introduced into the leg spring via the legs.
  • the blocking lever acts on the trigger lever by preventing in a blocking position rotation of the trigger lever about the axis of rotation, for example by the trigger lever presses against the blocking lever, and in a release position allows the rotation of the trigger lever about its axis of rotation,
  • an actuating lever is actuated, so causes this actuation of the actuating lever a delayed by the leg spring transition of the blocking lever from its blockage position to its release position.
  • the blocking lever blocks a rotation of the release lever.
  • the duration of actuation of the operating lever caused by the inertia of the handle is shorter than the delay time, so that it does not cause timely release of the locking mechanism.
  • the actuation of the actuating lever causes a force which is introduced into one of the legs of the leg spring.
  • the second leg of the leg spring interacts with the blocking lever. Since the blocking lever exerts a counter force on the leg force due to its inertia, there is a deformation of the leg spring, which is thus tensioned. From a dependent of the spring characteristic deformation of the Leg spring overcomes the force exerted by the leg spring on the blockage force, the mass inertia of the blocking lever and causes its transition from the blockage position to the release position. Until then, the blockage lever prevents rotation of the trigger lever.
  • the two actuating levers and the trigger lever are preferably designed such that an actuation of an actuating lever up to a first deflection of the actuating lever causes only a movement of the leg of the associated leg spring. Only from a second deflection, which is greater than the first deflection, the actuation of the actuating lever causes a rotation of the trigger lever. This results in a latency between the action of the actuating lever on the leg spring and on the release lever. The latency depends on the operating speed of the operating lever. If the latency is greater than the delay time caused by the leg spring, then the blocking lever is in its release position before the actuation of the actuating lever causes a rotation of the trigger lever. Otherwise, the blockage lever blocks the rotation of the release lever.
  • the motor vehicle door lock preferably has a lock case on which the rotary latch, the pawl, the Ausschöschebel, the blocking lever, the first operating lever and optionally the second operating lever are rotatably mounted.
  • the lock case is thus a carrier for rotatable components of KraftfahrzengtverInstitutes.
  • the lock case may form the housing or a part of the housing of the motor vehicle door lock.
  • the first operating lever is an external operating lever operable by a door handle on the outside of the motor vehicle
  • the second operating lever is an internal operating lever operable by a door handle on the inside of the motor vehicle.
  • the first operating lever is an inside operating lever and the second operating lever is an outside operating lever.
  • the second operating lever can directly, ie directly, act on the second leg spring, so move a leg of the leg spring.
  • the second actuating lever acts indirectly, ie indirectly, on the leg spring by a connecting lever or a connecting slide is arranged functionally between the second operating lever and the second leg spring.
  • the second operating lever moves the connecting lever or the connecting slide, which in turn acts on the second leg spring.
  • a connecting lever is pivoted by the second operating lever, a connecting slide is translationally moved by the second operating lever.
  • the connecting lever or the connecting slide on a groove which receives an angled end of a first leg of the second leg spring.
  • the second leg of the second leg spring acts on the blocking lever. If the connecting lever or the connecting slider is moved by an actuation of the actuating lever, this causes a movement of the first leg of the second leg spring, which generates a tension of the second leg spring. Since the angled end of the first leg of the second leg spring can move in the groove, movement of the connecting lever or the connecting slider produces only a pivotal movement of the first leg of the second leg spring, but no extension of this leg.
  • the axis of the first leg spring corresponds to the axis of rotation of the blocking lever.
  • the first leg spring and the blocking lever are seated on the same pin, so that the first leg spring is simultaneously fixed with respect to a movement perpendicular to its axis.
  • a leg of the first leg spring with respect to its axis rotatably connected to the blocking lever.
  • a movement of this leg of the first leg spring for example, due to a rotation of the main body of the first leg spring about its axis, thus producing an identical rotation of the blocking lever about its axis of rotation.
  • the blocking lever for example, a recess which receives an angled end of the leg of the first leg spring. This results in a positive connection between the angled end of the leg of the first leg spring and the blocking lever.
  • the axis of rotation of the blocking lever is parallel to the axis of rotation of the release lever. This simplifies blocking the rotation of the release lever by the blocking lever.
  • the axis of the second leg spring is parallel to the axis of the first leg spring.
  • the axes of the two torsion springs are preferably not identical.
  • the axes of rotation of the pawl, the trigger lever and the first actuating lever are identical.
  • the pawl, the release lever and the first confirmation lever are preferably mounted on the same pivot. This results in a simplified interaction between the components, in particular between the first operating lever and the release lever.
  • the blocking lever and the release lever are designed inhibiting. This means that the release lever prevents a transition of the blocking lever from its blocking position to its release position as long as the release lever presses against the blocking lever.
  • the release lever for example, a projection which prevents the passage of the blocking lever.
  • the locking remains locked as long as an operating lever is actuated.
  • the blocking lever and the release lever are configured such that the blocking lever can leave its blocking position in the direction of its release position while the release lever presses against the blocking lever.
  • FIG. 1 shows a three-dimensional view of the invention relevant components of a motor vehicle door lock.
  • Directional information refers exclusively to the representation in the figure and are thus only illustrative and not restrictive.
  • the motor vehicle door lock 1 has a lock case 2, which serves as a carrier for further components of the motor vehicle door lock 1.
  • a rotary latch 3 which has a recess for receiving a striker, not shown in the figure.
  • a pawl 4 Arranged around a common axis of rotation on the lock case 2 are furthermore a pawl 4, a release lever 5 and an external operating lever 6 as the first actuating lever.
  • the pawl 4 is closest to the lock case 2, the outside operating lever 6 farthest from the lock case 2 and the trigger 5 between the pawl 4 and the outside operating lever 6.
  • the pawl 4 is configured and arranged to rotate the rotary latch 3 can prevent its closed position shown in the figure clockwise by being in engagement with the rotary latch 3.
  • An inner operating lever 8 as a second operating lever is rotatably mounted on a lock housing, not shown.
  • the direction of the rotation axis of the inside operation lever 8 is perpendicular to the direction of the rotation axis of the outside operation lever 6.
  • the release lever 5 is configured and arranged such that a counterclockwise rotation about its axis of rotation, the pawl 4 out of engagement with the rotary latch 3 releases.
  • the release lever 5 is provided for example with a pin as a kind of driver, which dips into a recess in the pawl 4.
  • Such a rotation of the trigger lever 5 is generated by the operation of at least one of the operating levers 6 and 8.
  • each of the actuating lever 6 and 8 on a functional surface which can cooperate with a corresponding functional surface of the trigger lever 5 to rotate it counterclockwise about its axis of rotation.
  • a corresponding actuation of an actuating lever 6 or 8 takes place in the installed state of the motor vehicle door lock 1 by means of the actuation of an associated door handle, which causes an actuation of the associated actuating lever 6 or 8.
  • a blocking lever 11 which is rotatably mounted about an axis of rotation.
  • the axis of rotation of the blocking lever 11 is parallel to the axis of rotation of the pawl 4. of the trigger lever 5 and the external actuating lever 6.
  • the blocking lever 11 may occupy a release position in addition to its blockage position shown in the figure. In its blocking position, the blocking lever 11 prevents a rotation of the Auslöschebels 5 counterclockwise and thus a resolution of the engagement of the pawl 4 in the rotary latch. 3
  • a first leg spring 7 is arranged, the central axis of the axis of rotation of the blocking lever 11 coincides.
  • An angled end of a leg of the first leg spring 7 extends positively into a recess of the blocking lever 11.
  • An angled end of the other leg of the first leg spring abuts against a surface of the external operating lever 6.
  • a leg spring Analogous to the external operating lever 6 and the internal operating lever 8 is connected via a leg spring with the blocking lever 11.
  • a second leg spring 10 is arranged on the lock case 2.
  • the axis of the second leg spring 10 is parallel to the axis of the first leg spring 7.
  • the motor vehicle door lock 1 also has a connecting slide 9, which can execute a one-dimensional translational relative movement with respect to the lock case 2. In the figure, this relative movement is from left to right and vice versa.
  • the connecting slide 9 has an opposite to its direction of movement obliquely extending groove, which receives an angled end of the second leg spring 10.
  • the other leg of the leg spring 10 abuts against a side surface of the blocking lever 11.
  • the latter Upon actuation of the external actuating lever 6, the latter first exerts only a force on the adjacent leg of the first leg spring 7, the inertia of the blocking lever 11 exerts a force on the other leg of the first leg spring 7.
  • the external operating lever 6 is not yet in contact with the tripping lever 5 Thus, the external operating lever 6 biases the first leg spring 7 against the inertia force of the blocking lever 11. It should be noted that a frictional force is also added to the inertia force, so that a counterforce of the blocking lever 11 can be used.
  • the blocking lever 11 At a greater operating speed, the blocking lever 11 is still in its blocking position when the external operating lever 6 comes into contact with the triggering lever 5, thus preventing the rotation of the triggering lever 5.
  • a high operating speed such as generated by a side impact, a release of the rotary latch 3 prevented by the pawl 4, because the release lever 5 is blocked by the blocking lever 11.
  • an actuation of the inner actuating lever 8 initially exclusively leads to a tension of the second leg spring 10 before the inner actuating lever 8 comes into contact with the tripping lever 5. If the force exerted by the tensioned second leg spring 10 on the blocking lever 11 exceeds its counterforce, then this moves from its blocking position into its release position. Only from a further actuation of the inner actuating lever 8, this comes into contact with the trigger lever 5 and rotates about its axis of rotation, when until then the blocking lever 11 is in its release position.
  • a very short, jerky operation of an operating lever with an operating speed above an operating speed limit thus causes the trigger lever 5 is blocked during the actuation period by the blocking lever 11 and thus triggering of the locking mechanism 3 and pawl 4 is prevented.
  • the actuating levers 6 and 8 and the release lever 5 are configured and arranged such that an actuation of an actuating lever exerts an (additional or increased) force on the associated leg spring before the functional surface of the actuating lever cooperates with an associated functional surface of the trigger lever 5, to rotate the release lever 5 about its axis of rotation.
  • the beginning of the actuation of the actuating lever 6 or 8 thus initially acts only on the leg spring 7 or 10 and thus on the blocking lever 11, but not yet on the release lever 5.
  • a slow actuation of an operating lever 6 or 8 initially causes the rotation of the blocking lever his Blockadegna in its release position, before a rotation of the trigger lever 5 causes its axis of rotation acts.
  • a key aspect of the present invention is that both actuating levers 6 and 8 each act on a single, common blocking lever 11 via a leg spring 7 or 10.
