Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism, also with a working on the ratchet operating lever mechanism with release lever, and with a locking lever which blocks the ratchet at least when occurring acceleration forces of predetermined size, for example in an accident ("crash").
  • An operating lever mechanism is usually composed of one or more levers. Usually, an Innbet Ober Trentshebel, 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 is to unintentional opening in the event of a crash in structurally simplified design are made available, Also, a permanent blocking of the opening lever is basically addressed.
  • a crash lock on a door lock is described.
  • This has a pivoting locking lever, which can pivot by mass force about its pivot axis in a blocking element locking a transmission element.
  • a counter-locking surface is provided, which is designed stationary.
  • a motor vehicle door lock according to the preamble of claim 1 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) 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 latch comprising at least one latch with a catch and a pivotable first latch, wherein a trip lever is moved so that the trip lever cooperates with a drive pin of the first latch during its movement and a side pawl spring abuts between the pintle and the trip lever during the interaction , Disclosed is still a motor vehicle door lock, with a locking mechanism, further with a working on the locking mechanism operating lever with a release lever, and with a locking lever which blocks the locking, wherein the locking lever relative to the locking mechanism in normal operation is in blocking position or releases.
  • the DE 20 2006 012091 U1 discloses a motor vehicle lock with latch and pawl, wherein the latch can be brought into 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.
  • a generic motor vehicle door lock in the invention is characterized in that the locking lever and the release lever are elastically coupled by at least one spring and connected to each other and the inertia forces of the locking lever occurring in the event of a crash any coupling forces to the trigger more or less clear exceed.
  • the locking lever is thus practically in a permanently active state. Because the locking lever stands for the blockage of the locking mechanism in the non-actuated state, so in the event that the motor vehicle door lock is at rest and the locking mechanism is not deflected in a blocking adjustment. Typically, the deflected ratchet in normal operation causes it to be opened. For this purpose, usually the pawl is lifted from the catch.
  • the last-described functional state of the locking opening corresponds to the opening normal operation, provided that excessive acceleration forces do not act on the motor vehicle door lock in question.
  • the interpretation in the context of the invention is such that the locking lever is in the non-actuated state in Blockadegna.
  • D. h. The locking lever does not change its relative position compared to the locking mechanism even in the event of a crash and is contrary to a movement of the locking mechanism. This is essentially due to the fact that the locking lever is balanced in itself, ie the center of gravity is located in the pivot point of the locking lever.
  • the locking lever is typically pivotable about an axis pivoting lever.
  • the locking lever is usually stored together with the locking mechanism in a lock case, which provides the necessary rigidity and position accuracy to the aforementioned components and their storage.
  • the locking lever is usually a two-arm lever with blocking arm and balance arm.
  • the locking lever is preferably coupled to the operating lever mechanism.
  • the locking lever is connected to a release lever of the operating lever mechanism.
  • the release lever works as usual on the locking pawl of the locking mechanism, namely to its opening in a lifting sense. So as soon as the release lever is pivoted to remove the locking pawl of the pawl and lift the pawl of the catch and thus open the locking mechanism, this pivoting movement ensures at the same time that the locking lever is acted upon by the spring. In normal operation, this deflection of the release lever causes the locking lever via the spring between the release lever and the locking lever, as it were "taken” becomes. As a result, the lock lever can not block the lock in the described normal opening operation.
  • the moment of inertia of the locking lever is designed so that even the tensioned by the release lever spring between the release lever and the locking lever can not pivot this.
  • the locking lever can block the locking mechanism in the event of a crash if the masses of lever mechanism and locking mechanism and the spring coupling the release lever with the locking lever can not overcome the moment of inertia of the locking lever in the tensioned state. As a result, there is practically no relative movement between the blocking pawl and the locking lever in the event of a crash. The locking lever thus ensures in the event of a crash for the desired blockage of the locking mechanism.
  • the coupling between on the one hand the locking lever and on the other hand the locking mechanism for example, by a cam, a molding, etc. can take place.
  • the locking lever may have the cam in question or a shape that interact with the blocking pawl.
  • the reverse can also be done.
  • the contour is to be designed so that the blocking pawl rotating in the open direction can not initiate any opening torque into the blocking lever.
  • a motor vehicle door lock which initially has a particularly high reliability. Because of the locking mechanism associated with the locking lever is operated at virtually every deflection in normal operation. For this purpose, it is only necessary that the release lever of the actuating lever mechanism is pivoted into the locking mechanism opening sense. In this process, the release lever takes over the intermediate spring with the locking lever, so that as a result, the locking pawl is no longer blocked and can be lifted by the release lever with respect to the catch.
  • a motor vehicle door lock which is equipped with a locking mechanism 1, 2, 3 of a rotary latch 1, a locking pawl 2 and a pawl 3.
  • a working on the locking mechanism 1, 2, 3 release lever 4 is provided.
  • the release lever 4 In order to open the ratchet 1, 2, 3, the release lever 4 must be pivoted about its axis 5 in a clockwise direction, as an arrow drawn in the figure makes clear. As a result, the release lever 4 engages with an edge 6 on a pin 6 'of the blocking pawl 2. As a result, the locking pawl 2 rotates counterclockwise in accordance with the indicated direction of the arrow about its axis 7. Once the locking pawl 2 is lifted from the pawl 3, the catch 1 can pivot about its axis 8 spring assisted clockwise and release a merely indicated locking pin 9. The locking pin 9 is connected to a motor vehicle door, not shown.
  • a locking lever 10 which is rotatably mounted about an axis 11.
  • the axis 8 of the catch 1, the axis 7 of the blocking pawl 2, the axis 5 of the release lever 4 and finally the axis 11 of the locking lever 10 are defined in total in a lock case 12.
  • it may in each case be bearing journals which are aligned substantially parallel to one another and for the most part stand upright on a base surface of the lock case 12. This is of course only to be understood as illustrative and not restrictive.
  • the locking lever 10 is formed as pivotable about its axis 11 pivot lever 10. As already explained, the locking lever 10 is mounted together with the locking mechanism 1, 2, 3 in the lock case 12.
  • the locking lever 10 is a two-arm lever with a blocking arm 10a and a balance arm 10b.
  • the blocking arm 10a represents the blocking pawl 2 facing arm of the locking lever 10, whereas the compensating arm 10b of the blocking pawl 2 faces away.
  • the blocking arm 10a is equipped with a recess or recess 13 in which an edge 13 'of the blocking pawl 2 engages.
  • the reverse can also be done.
  • the blocking pawl 2 has a molding 13 and the locking lever 10 is equipped with a corresponding edge 13 '.
  • the locking lever 10 is conceivable and is encompassed by the invention. Either way, the locking lever 10 in the normal operation shown in the figure ensures that the locking pawl 2 is blocked in the event of a crash and can not perform the direction indicated in the opening case counterclockwise movement about the axis 7, which is initiated by the release lever 4 during its operation , In other words, the locking mechanism 1, 2, 3 is blocked because the blocking pawl 2 experiences the blockage described by the locking lever 10.
  • the locking lever 10 is coupled to the release lever 4.
  • an elastic coupling in the form of a spring 14 is provided at this point.
  • This spring 14 connects the locking lever 10 and the release lever 4 with each other.
  • the spring 14 preferably engages the blocking arm 10a of the blocking lever 10.
  • the design in the exemplary embodiment is such that the release lever 4 and the locking pawl 2 are arranged with their respective axes 5, 7 on a connecting line and, in contrast, the locking lever 10 is located below its arrangement. D. h., The locking lever 10 is placed below the connecting line through the two axes 5, 7 on the one hand the trigger lever 4 and on the other hand, the blocking pawl 2.
  • the actuating edge 6 acting on the blocking pawl 2 ensures that the blocking pawl 2 completes the counterclockwise movement indicated in the figure about its axis 7. Subsequently, the pawl 3 can be lifted from the catch 1, which in turn opens spring-assisted and releases the previously captured locking pin 9. For this corresponds to the normal operation, in which the locking lever 10, the locking mechanism 1, 2, 3 and the blocking pawl 2 releases.
  • a spring, not shown, on the blocking lever 10 ensures that the blocking lever with the movement of the Release lever 4 in the starting position also in the non-actuated state, the rest position is returned.
  • the trigger lever 4 can be deflected depending on the acceleration forces occurring and depending on the direction of force. That is, the trip lever 4 would experience a comparable clockwise action about its axis 5 as in a "normal” operation. In contrast to this "normal” operation but in the event of a crash on the locking lever 10 and also blocked by him blocking pawl 2 act inertial forces.
  • the moment of inertia of the locking lever 10 is designed so that in the described crash case, there is no relative movement of the locking lever 10 and the blocker latch 2 is blocked by the locking lever 10.
  • the design is such that the deflected in the assumed crash case release lever 4 with the thus tensioned spring 14, the locking lever 10 also can not deflect and the blockage of the locking mechanism 1, 2, 3 thus occurs.
