Definitions

  • the present invention relates to a lock unit comprising at least one rotary latch, in which the rotary latch has a main catch and a preliminary catch.
  • An additional main pawl with a Haupttrastklinkenburnachse and a blocking pawl are also provided, wherein the blocking pawl fixes the main latch when engaged with the catch.
  • a lock unit has a pre-latching pawl which is rotatably mounted on the main latching axis of rotation and can be brought into engagement with the rotary latch.
  • Such lock units are used in particular to lock doors and / or flaps in motor vehicles.
  • Such a lock unit is for example from the WO 2008/061491 A1 out.
  • the positions of the catch and the main catch of the catch are on different levels and are served by two separate levers, namely the release lever (for the pre-rest) and the pawl (for the main catch) ,
  • the locking has proven itself, but can be further improved.
  • lock units in this context, in particular, a reduction in the triggering forces and an increase in the operating comfort are in the foreground.
  • these are components which are made available in large quantities as part of series production, so that manufacturing and cost-specific aspects must also be taken into account are.
  • the integration of such lock units in motor vehicles must also take into account the limited space available and the maintenance of the function over a long period of time and a variety of actuation actions.
  • the noise of the lock unit or the locking mechanism plays an important role in its operation.
  • a lock unit which has at least one rotary latch in which the catch has a main catch and a pre-rest, a main pawl with a Hauptastastklinkenburnachse, a blocking pawl which fixes the main pawl in engagement with the rotary latch, and a Vorrastklinke on the Main locking ratchet axis of rotation rotatably mounted and can be brought into engagement with the rotary latch.
  • the lock unit has at least one elastic element which, at least at times, the blocking pawl and the pre-locking pawl clamped against each other, wherein the bias in the open position is preferably greatest.
  • Such a lock unit is usually arranged in a (at least partially) sealed lock housing, which is arranged on the body, in particular the door, of the motor vehicle.
  • a lock unit has a locking mechanism, wherein the rotary latch is a central component.
  • the catch serves to fix a lock holder arranged on the body (also called a locking bolt or striker).
  • the catch partly encloses the lock holder in its closed position. In this closed position, the main pawl abuts the main catch of the catch.
  • the main catch is in particular a recess or projection formed on the circumference or the side surface of the rotating surface.
  • the main pawl is rotatably supported on a main catch pawl rotational axis which is remote from the rotation axis of the catch.
  • the catch has in addition to its open position and its closed position still an intermediate position, the so-called pre-rest position.
  • the rotary latch In this pre-locking position of the closing operation of the lock unit or the vehicle door, not completely completed, however, the rotary latch is already blocked motion to prevent the lock holder is released.
  • the pre-locking pawl engages the catch, namely by contacting the catch of the catch.
  • the pre-catch can be formed as a projection or recess on the circumference or a side surface of the rotary latch.
  • the main latch and the Vorrastklinke are mounted on a common Haupttrastklinkenburnachse and can, in particular due to their temporally offset engagement with the catch against each other are relatively pivoted.
  • the arrangement of the main pawl and the Vorrastklinke on one axis leads to a particularly compact design of the locking mechanism.
  • the main pawl, the Blocking pawl and / or the Vorrastklinke is a metal component, which is designed in particular in the manner of a punching component.
  • the blocking pawl which blocks the self-opening mechanism, is now in particular positioned so that it rests against the main catch on the side opposite the catch. Thus, it counteracts the pivotal moment generated by the rotary latch with respect to the main latch.
  • This blocking pawl is preferably also arranged pivotably.
  • an elastic element which acts between the blocking pawl and the pre-locking pawl in such a way that these components are braced against one another, a movement of the one component can thus be transmitted via the elastic element in the other component.
  • This interaction of the elastic element with the blocking pawl and the pre-locking pawl need not be present for all positions of the lock unit, however, such an embodiment is preferred.
  • the elastic element is in particular designed or arranged such that by a movement of the blocking pawl and / or the Vorrastklinke a changed spring force between these components is generated. Most preferably, the greatest spring force is provided when the lock unit is in the open position.
  • a positive spring force should also be provided in the closed position.
  • the blocking pawl acts on the main pawl in the closed position, so that it is positioned in front of the main catch of the rotary latch, but additionally the pre-catch is biased via the elastic element towards the rotary latch, so that it is in particular in a predetermined, defined position is fixed and is stored quietly in the operation of the motor vehicle and the vibrations occurring.
  • the elastic element can also be designed in several parts, but a one-part design is preferred.
  • a plurality of elastic elements can also act between the blocking pawl and the pre-locking pawl, but with a view to a reduced number of parts, the provision of a single elastic element is likewise preferred here.
  • the elastic element is most preferably made with a metallic material.
  • the at least one elastic element induces a torque both in the blocking pawl and in the pre-locking pawl, at least during the closing operation of the lock unit.
  • the elastic element acts in particular in the manner of a return spring for these components, which should thus take their preferred detent positions.
  • the restoring force by means of the elastic element in the arrangement of blocking pawl and Vorrastklinke in the open position of the catch to the position Vorrast be greatest, then be partially degraded, the remaining spring force is sufficiently large, the locking pawl upon reaching the position of the main catch in front of the main pawl to pivot.
  • a (residual) spring force acting between blocking pawl and pre-latching pawl is also preferred in this phase.
  • the safety during operation of the lock unit is additionally increased.
  • many single-acting return springs are used, but nevertheless allow a closing operation when one of the return springs, e.g. is broken. This does not reveal to the user that there is a malfunction.
  • the elastic element comprises a spring, wherein the spring is preferably stored together with the blocking pawl.
  • the elastic element may basically comprise further components, but the embodiment with a single spring is preferred.
  • the spring is most preferably provided with a wire-shaped element.
  • this spring is mounted on the axis of rotation of the locking pawl. In principle, it is possible that a part of the spring is positioned stationary, but it is also possible that the spring can rotate about the axis of rotation of the locking pawl, namely, depending on the different positions of locking pawl and / or Vorrastklinke.
  • the elastic element, or the spring cooperates with an outer contour of the blocking pawl and / or the pre-locking pawl, but it is also possible for the elastic element or the spring to fit in a corresponding recess (for example the spring) side surface) the locking pawl and / or the Vorrastklinke engages (for example in the manner of a bore).
  • an embodiment of the lock unit is preferred in which the blocking pawl and / or the Vorrastklinke is connected to an actuating element.
  • the actuating element may in particular be designed in the manner of a lever and serves e.g. for initiating the opening process, wherein it is connected by means of a lever mechanism and / or Bowden cables with a handle of the door. With the actuating element, the blocking pawl and the pre-latching pawl, e.g. be moved simultaneously or at different times. Even a single operation is possible.
  • the main latch can be brought into engagement with the main latch and the latch can be brought into engagement with the latch, the main latch and the main latch being arranged in a first plane and the latching latch and the latching device being in a second plane.
  • a blocking of the rotary latch takes place in two planes perpendicular to the axis of rotation of the rotary latch.
  • the pre-restraint is e.g. formed in the manner of a projection laterally on the rotary latch. It is very particularly preferred that the blocking pawl is also arranged in the first plane.
  • a first leg of the elastic element with a first link of Vorrastklinke at least temporarily is present and that a second leg of the elastic member at least temporarily abuts with a second link of the blocking pawl, wherein the first leg of the elastic member in the second plane and the second leg of the elastic member in the first plane is arranged.
  • the first leg and the second leg of the elastic element are preferably L-shaped, while the region of the elastic element connecting the legs, in particular a wire-shaped one, is arranged spirally around the bearing of the blocking pawl. The legs contact with the short, bent end portion of the first gate of Vorrastklinke, or the second gate of the blocking pawl on the peripheral region.
  • the first leg during the movement of the pre-locking latch can run relatively freely on the first link of Vorrastklinke or is guided along this first link of Vorrastklinke.
  • the first link of the pre-locking pawl preferably forms a guide section of several millimeters, for example up to 5 mm or up to 10 mm.
  • such a free fixation of the second leg is not realized on the blocking pawl, but rather a fixed position is realized to the blocking pawl. This is particularly favored by the fact that the contact point of the second leg rotates at the blocking pawl in a joint attachment and thus the distance to the storage is not changed.
  • the pre-locking pawl on a Drehwinkelbegrenzungsarm which rests temporarily on a Drehwinkelbeskyr.
  • the Vorrastklinke so not only has an arm, which is ultimately brought before the pre-rest of the catch to the plant, but also a, in particular laterally projecting, smaller running Drehwinkelbegrenzungsarm.
  • a Drehwinkelbeskyr is provided in this lock unit, in particular in a position between the Vorrastklinke and the blocking pawl.
  • This Drehwinkelbeskybeskyr may be designed pin-shaped and optionally be surrounded by a damping material.
  • the pre-locking pawl If the catch has reached a position which lies between the pre-locking position and the main-locking position, the pre-locking pawl is pressed by means of the elastic element in a position that the Drehwinkelbegrenzungsarm rests against the Drehwinkelbeskyr. In other positions of the rotary latch toward the open position, the pre-latching pawl bears against the rotary latch itself and is therefore fixed in a predetermined position by means of the elastic element and the rotary latch itself.
  • the invention finds particular application in a motor vehicle having at least one lock unit described here according to the invention.
  • FIG. 1 schematically shows a lock unit 1 of a simplified only indicated here motor vehicle 11.
  • the locking mechanism consisting of a rotary latch 2, a main latching pawl 3, a blocking pawl 5 and a pre-latching pawl 6, is arranged in a housing 20 which is positioned, for example, in or on a motor vehicle door.
  • the lock unit 1 has the task, for example fixed to the vehicle body lock holder 21 to fix in the closed position.
  • the rotary latch 2 which is usually rotatably mounted on a rotary latch axis 23, has a lock holder recess 22, a main catch 8 and a preliminary catch 9.
  • the lock holder 21 is securely received in the lock holder recess 22 of the rotary latch 2.
  • the rotation (clockwise here) of the catch 2 due to the spring bias is hindered by the fact that the main pawl 3 rests against the main catch 8 of the catch 2.
  • a force is introduced from the catch 2 into the main pawl 3, which is not directed to the Haupttrastklinkenburnachse 4 ("self-opening mechanism"). From the introduced through the catch 2 to the main pawl 3 force results in the main latch 3, a torque 24 in the clockwise direction.
  • the main pawl 3 is locked against pivoting in a clockwise direction by a blocking pawl 5 which is rotatably mounted on the blocking pawl rotational axis 26.
  • the blocking pawl 5 forms a stop 25 in the closed position of the lock unit 1 for the main catch pawl 3, wherein the contact force applied thereto passes through the blocking pawl rotational axis 26.
  • the main pawl 3 is securely fixed to the main catch 8 of the catch 2. Consequently, a secure positioning of the main pawl 3 by the blocking pawl 5 can be ensured even in a further, counterclockwise rotation of the rotary latch 2 (for example, when squeezing the door seal).
  • This elastic element 7 is designed in the manner of a (return) spring 10 and has a first leg 14 and a second leg 15.
  • the first leg 14 is engaged with a first link 16 of the pre-latching pawl 6 and the second leg 15 is engaged with a second link 17 of the blocking pawl 5 in engagement.
  • the first link 16 and the second link 17 are provided so as to allow sliding of the end portions 28 of the first leg 14 and the second leg 15 on the respective surface (guide portion 29).
  • a second plane 19 located higher up with respect to the observer plane (cf. Fig. 2 ) is located on the catch 2, the pre-catch 9, which is in the so-called pre-locking position (not shown here) with the pre-catch 6 in contact.
  • the Fig. 2 now shows the just described lock unit 1, which is installed in or on a motor vehicle 11 shown schematically here, in a perspective view.
  • the spatial arrangement of the individual elements of the lock unit 1 is particularly clear. So lets the Fig. 2 , recognize that the pre-catch 9 of the rotary latch 2, the Vorrastklinke 6 and the elastic member 7 are at least substantially in the second plane 19, whereas The remaining elements of the lock unit 1: rotary latch 2, main latch 3 and blocking pawl 5 are at least substantially in the first plane 18.
  • an actuating element 27 is provided here, that simultaneously actuates the blocking pawl 5 and the pre-latching pawl 6, wherein the actuating element 27 is designed, for example, as a rotatably mounted lever plate.
  • Fig. 1 and Fig. 2 illustrated device can be carried out in different ways, in particular with regard to the shape and the number of individual elements.
