Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism, also with a working on the locking mechanism lever mechanism with release lever, and with a locking lever, which blocks the locking at least when occurring acceleration forces of predetermined size, for example in an accident ("crash").
  • the operating lever mechanism is usually composed of one or more levers. Usually, an Innbetuschistshebel, an external operating lever and a release lever are used in the minimum. In addition, the operating lever mechanism often also includes a clutch lever. If the actuating lever mechanism is acted upon, the locking mechanism can be opened in this way. For this purpose, typically the release lever engages a pawl of the ratchet and lifts it from an associated catch. The catch then opens spring-assisted and releases a previously captured locking pin. As a result, an associated motor vehicle door can be opened.
  • An acting on an operating lever mechanism locking lever is, for example, in the DE 197 19 999 A1 presented.
  • the lock or the blocking lever blocks an opening lever when the accelerating forces described in the course of an accident.
  • the lock or the locking lever and the opening lever are arranged transversely to the pivoting direction of the opening lever relative to each other displaceable. When caused by the increased acceleration forces relative displacement of the opening lever runs into the lock. This should be an unintentional opening in the event of a crash in structurally simplified design available. Also, a permanent blockage of the opening lever is basically addressed.
  • a crash lock on a door lock is described.
  • This has a pivotable locking lever, which can pivot by inertia force about its pivot axis in a locking element arresting a locking position.
  • a counter-locking surface is provided, which is designed stationary.
  • a motor vehicle door lock according to the preamble of the claim is known, which is provided with a lockable by a pawl in a closed position and after a by actuation of a pawl actuator (28) caused pivoting of the pawl from this blocking position in a release position movable catch.
  • this document proposes that the pawl is movement blocked in its blocking position by a vorlösbaren upon actuation of the pawl actuating member to be designated as a blocking lever blocking member.
  • the locking lever blocks both in undisturbed normal operation and in the event of a crash, the pawl and releases it only for deflected normal operation.
  • the WO 2009/150225 A2 discloses a closure device having at least one
  • a motor vehicle door lock with a locking mechanism, also with a working on the locking mechanism operating lever with a release lever, and with a locking lever which blocks the locking mechanism, wherein the locking lever relative to the locking mechanism in normal operation is in blocking position or releases.
  • the DE 20 2006 012091 U1 apparently a motor vehicle lock with lock latch and pawl, wherein the latch is engageable in a main latching position, in a Vorrastrus and in an open position and wherein the pawl in a sunken position in which it holds the latch in the main latching position and in a raised position, in the it releases the latch, is adjustable, wherein the pawl by means of an actuating mechanism in an actuating operation can be lifted and wherein an adjustable locking lever is provided which can be brought into a blocking position and in at least one release position, wherein the blocking lever located in the blocking position (4) a Lifting the pawl (2) blocked.
  • the invention is based on the technical problem of finding an alternative locking lever arrangement.
  • an elastic coupling is further provided in a generic motor vehicle door lock, wherein the locking lever and the operating lever mechanism are connected by at least one spring and the inertial forces of the locking lever occurring in the event of a crash exceed any coupling forces to the operating lever more or less significantly.
  • Normal operation means in the context of the invention functional states of the motor vehicle door lock, in which only acceleration forces occur that correspond to normal driving dynamics processes.
  • the locking lever is still active, so permanently active. Because the locking lever is in its blocking position both in the unactuated state during normal operation and in the event of a crash. In this functional position, the locking lever acts on the pawl for the locking mechanism in the direction of its blocking position. In other words, take the locking lever, the pawl and consequently also the locking mechanism in normal operation as well as in the event of a crash in each case the blocking position.
  • the locking lever Only when opening in normal operation, the locking lever allows the release position of the pawl and thus the locking mechanism, so there are thus the locking lever, the pawl and thus the locking mechanism in their respective release position.
  • a release lever of the operating lever mechanism does not work in the opening sense on the locking mechanism, but in this respect is at rest.
  • the release lever thus does not work on a pawl of the composite of the catch and pawl locking mechanism in the opening sense.
  • the operating lever mechanism is in peace compared to the locking mechanism.
  • the trigger lever is deflected to deflect a blocking pawl and lift the pawl from the catch.
  • the catch is released from the pawl and can spring-assisted transition to its open position.
  • a previously captured locking pin is released. Since the locking bolt is typically connected to a motor vehicle door, the motor vehicle door also comes free in this process.
  • the locking lever In normal operation as well as in the event of a crash, the locking lever is permanently active in its blocking position. Because the locking lever ensures that the Pawl remains in its blocking position. In this blocking position the pawl holds the ratchet or fixes the ratchet. For this purpose, the pawl attack on the catch and fix them in their main rest position or closed position. In the event of a crash, the mass moment of inertia of the locking lever ensures that it does not follow any movements of the operating lever mechanism and also can not follow, and that Crash therapiessuncol.
  • each opening operation for the locking mechanism corresponds in the context of the invention to a loading of the locking lever, which is transferred from its blocking position to the release position.
  • each normal actuation and release operation causes the locking lever to be moved. Any corrosion, caking, etc. as in the prior art can not occur hereby. As a result, the reliability is increased in a structurally simple structure.
  • the locking lever is designed as a pivotable about an axis pivoting lever.
  • the locking lever is typically stored together with the locking mechanism in a lock case.
  • the blocking arm preferably engages the pawl, at least in such a way that the pawl can be released for opening.
  • the locking lever is coupled to the release lever of the actuating lever mechanism.
  • the elastic coupling according to the invention has proved to be particularly favorable, because in this way, in particular in the event of a crash, the locking lever can remain at rest and yet any movements of the operating lever mechanism are allowed. However, such movements of the operating lever mechanism are not transmitted to the locking lever or blocked by him locking mechanism.
  • the locking lever and the release lever are connected by at least one spring.
  • the spring can engage the blocking arm of the blocking lever.
  • the release lever is acted upon in such a way that it actuates the blocking pawl and lifts the pawl from the closed catch.
  • the release lever acts simultaneously on the spring elastically coupled thereto locking lever.
  • the locking lever can release the pawl in this process, the locking lever may interact with the pawl locking contour, a cam, a molding, etc. have. In this case, any game between the locking lever and the pawl is dimensioned so that the process described goes smoothly vonstatten.
  • the locking lever interacts according to the invention with the pawl.
  • the pawl in turn attacks the catch of the locking mechanism.
  • the pawl may be mounted on the operating lever mechanism.
  • a bearing of the pawl takes place below the release lever.
  • the blocking pawl may attack on one edge of the rotary latch. Any movements of the actuating lever mechanism thus do not lead to a locking opening as long as the blocking pawl is lifted from the pawl.
  • the pawl interacts with the locking lever, which in turn is mounted on the release lever. Only when the locking lever assumes its release position, the pawl can be removed from their engagement with the ratchet and the catch free with the pawl lifted.
  • the moment of inertia of the locking lever is designed so that even in the event of a crash and the occurring here abnormal acceleration forces virtually no relative movement of the locking lever takes place.
  • the pawl and the locking lever thus remain even in such a case at rest, so that this also applies to the locking mechanism. Unintentional openings of the locking mechanism are thereby excluded.
  • the interpretation is usually made so that the inertial forces of the locking lever occurring in the event of a crash any coupling forces to the operating lever mechanism exceed more or less clearly.
  • the locking lever is advantageously coupled elastically via the addressed spring with the release lever.
  • the inertia forces acting on the locking lever are designed significantly larger than any of the coupling spring constructed tensile forces, which are transmitted for example from the deflected release lever on the locking lever.
  • FIGURE shows a motor vehicle door lock according to the invention schematically.
  • a motor vehicle door lock which is equipped with a locking mechanism 1, 2, 3 from a rotary latch 1 of a blocking pawl 2 and a pawl 3.
  • the locking mechanism 1, 2, 3 is mounted in a lock case 18.
  • the rotary latch 1 has a corresponding axis 4 and the blocking pawl 2 is also equipped with its own axis 5.
  • actuating lever mechanism 6, 7, which is composed of a release lever 6 and a further connected lever 7 or more other levers.
  • the must Release lever 6 are rotated by the operating lever mechanism 6, 7 in the clockwise direction about its axis 8, as an indicated arrow makes it clear.
  • Such a rotation of the trigger lever 6 causes the trigger lever 6 engages with an edge 9 on a pin 10 of the locking pawl 2.
  • the clockwise movement of the trigger lever 6 in this process corresponds to the fact that the blocking pawl 2 performs a counterclockwise movement about its axis 5.
  • the rotary latch 1 is spring-assisted by its closed position shown in the figure by clockwise rotation in an open position and this case releases a previously captured locking pin 17.
  • the locking bolt 17 is connected to a motor vehicle door, not shown, which also comes free in this process and can be opened.
  • the pawl 3 ensures that the locking mechanism 1, 2, 3 is held in the closed position.
  • the blocking pawl 2 thus acts - if you will - as an additional backup of the catch 1, in addition to the pawl. 3
  • the control of the pawl 3 from the blocking position to the release position (and back) is carried out according to the invention by means of a release lever 6, wherein a locking lever 12 is transferred from its blocking position into a release position.
  • the locking lever 12 is formed as pivotable about an axis 13 pivot lever 12.
  • the locking lever is designed as a two-armed lever and has a Blockadearm 12a and a balance arm 12b.
  • the blocking arm 12a interacts with the already mentioned pawl 3.
  • the locking lever 12 is mounted with its axis 13 together with the locking mechanism 1, 2, 3 in the lock case 18.
  • the respective axes 4, 5, 8 and 13 are arranged on the one hand of the rotary latch 1, the blocking pawl 2 and on the other hand, the pawl 3 and the release lever 6 and finally the locking lever 12 each parallel to each other , All axes 4, 5, 8, 13 are each substantially perpendicular to a ground plane of the lock case 18 and are each anchored in the lock case 18.
  • the locking lever 12 is coupled to the actuating lever mechanism 6, 7.
  • an elastic coupling in the form of a spring 14 is realized.
  • the spring 14 connects in the exemplary embodiment, the release lever 6 with the locking lever 12.
  • the spring 14 engages the blocking arm 12a of the locking lever 12.
  • the locking lever 12 is equipped with a cam or a molding 15 which interacts with a counter-element 16 on the pawl 3.
  • the locking lever 12 has on its Blockadearm 12 a via a recess 15. In this recess 15 engages a arranged on the pawl 3 cam 16 a.
  • the locking lever 12 performs an indicated counterclockwise movement about its axis 13.
  • the locking lever 12 takes its release position shown in phantom.
  • This counterclockwise movement of the locking lever 12 about its axis 13 is caused by the fact that in normal operation of the trigger lever 6 about its axis 8 is pivoted clockwise to open the locking mechanism 1, 2, 3.
  • the actuating lever mechanism 6, 7 acted upon by a door handle, for example, an inside door handle or outside door handle pulling accordingly. This indicates an arrow.
  • the blocking pawl 2 Since the process described and the clockwise rotation of the release lever 6 simultaneously applied with the help of the stop edge 9 the pin 10 on the blocking pawl 2, the blocking pawl 2 is actuated synchronously and the pawl 3 automatically or via a not shown further contour on the trigger lever 6 of the catch 1 lifted. At the end of this process, the catch 1 is free and can pivot starting from the closed position in the figure clockwise about its axis 4 and release the previously captured locking pin 17.
  • the locking lever 12 remains in its blocking position and ensures that the locking pawl 3 for the locking mechanism 1, 2, 3 is likewise acted upon in the direction of its blocking position. That is, the locking lever 12 remains at rest and as a result thereof interacting with the locking lever 12 pawl 3, both levers unchanged maintain their blocking position and thereby hold the catch 1 in the closed state. This position of normal operation is maintained even in the event of a crash. The moment of inertia of the locking lever 12 ensures that it does not come in the event of a crash to a relative movement of the locking lever 12, so that the two locking lever 12 and pawl 3 relative to each other remain at rest.
  • the locking lever 12 acts on the pawl 3 of a locking mechanism 1, 3, which is executed without blocking pawl 2 in the form described, wherein the trigger lever 6 acts directly on the pawl 3.
