Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism, further comprising at least one actuating lever for triggering the locking mechanism, and with a locking lever pivotable about an axis, which locks the locking mechanism at least at deceleration forces of predetermined size and direction, for example in the event of an accident ("crash case"). , ineffective.
  • the locking mechanism typically consists of a catch and a pawl.
  • the locking mechanism When occurring in conjunction with an accident deceleration forces of predetermined size and direction, there is a fundamental risk that the locking mechanism will open unintentionally, because the deceleration forces act on the actuating lever to trigger the Gesperres.
  • Such inadvertent openings in particular in the event of an accident, prevent the locking lever which, in the case of the deceleration forces of predetermined magnitude and direction, sets the locking mechanism inoperative.
  • the mentioned deceleration forces or associated vehicle accelerations mostly act in the transverse (ie in the Y) direction of the motor vehicle and occur mainly in the event of a side impact.
  • the locking lever is equipped with a stop recess.
  • the stop recess engages in blockade case acted upon pawl or beaufschlagtem actuating lever in an opening of a counter-locking surface a form-fitting.
  • the desired blockage of the release lever or locking mechanism is given under all conceivable circumstances and in particular during the entire time within which the mentioned delay forces occur, maintained. That has proven itself.
  • the procedure is such that the blocking lever is assigned a blocking means which fixes the blocking lever in its deflected position. In this deflected position, the locking lever only goes over when the motor vehicle door lock is subjected to acceleration forces or deceleration forces of a predetermined magnitude and direction, for example those which are observed in the event of an accident.
  • the locking lever is mechanically deflected in the teaching of WO 2012/013182 A2 and ensures that the at least one operating lever or the entire operating lever mechanism is mechanically ineffective or is set ineffective. In this way, a simple and functional design is realized and malfunction can be virtually ruled out even after years or decades of use. Because the locking lever performs in normal operation at a loading of the operating lever mechanism or the actuating lever relative movement, so that overall the mobility of the locking lever is ensured and corrosion, caking, etc. need not be feared. That has proven itself.
  • the phenomenon may occur when recourse to such locking lever and in the event of a crash that the operating lever tends to so-called "bouncing". That is, the operating lever is initially blocked during the accident by the locking lever and then bounces off the locking lever or slightly away from the locking lever to then apply again by the unchanged applied deceleration forces on the locking lever. This may still lead to an unwanted opening during a crash. This is to be avoided at all costs, so that the locking mechanism and consequently the motor vehicle door remain closed and the safety devices typically present in a side door can have their full effect. This is where the invention starts.
  • the invention is based on the technical problem of further developing such a motor vehicle door lock so that unintentional opening of the locking mechanism can be reliably precluded, and indeed also and in particular during a crash process. Specifically, in particular, the previously explained “bouncing" of the operating lever relative to the locking lever to be avoided.
  • a generic motor vehicle door lock in the invention is characterized in that the locking lever is eccentrically mounted on the or its axis and thereby generates a function of the occurring deceleration forces an operating lever blocking counter-torque.
  • the locking lever for this purpose has a focus located above or below its axis, which in response to the occurring deceleration forces (and their direction) which generates the operating lever blocking counter-torque on the locking lever.
  • the eccentric arrangement of the center of gravity compared to the axis for the locking lever ensures that at the occurring deceleration forces on the locking lever, a torque is generated about the axis.
  • This torque is designed overall as a counter-torque in comparison to a rotational movement of the actuating lever (in the opening sense or in the "crash").
  • the direction of the counter-torque on the locking lever and that of the actuating lever in the event of a crash are thus directed in opposite directions.
  • the locking lever is typically equipped with a stop against which the actuating lever moves in the event of a crash and is thereby blocked. Since the locking lever in addition by the attacking deceleration forces has the counter-torque in question with respect to its axis, this counter-torque acts counter to the direction of the actuating lever, which in the Crash case executes. As a result, the previously mentioned “bouncing" of the actuating lever is counteracted. For as soon as the actuating lever leaves its position on the stop of the locking lever during the crash due to such a bouncing process, the counter-torque acting on the locking lever ensures that the locking lever can, as it were, follow the actuating lever that lifts off the stop in the short-term.
  • the center of gravity is arranged in the axial extension above or below the axis of the locking lever.
  • the invention favors an axial center of gravity arrangement above the axis of the locking lever, although this is generally not mandatory.
  • Such a counter-torque is always conceivable and representable when the center of gravity of the locking lever - as realized in the invention - does not coincide with the axis of the locking lever about which this is pivotally mounted. This is the essence of the eccentric bearing according to the invention.
  • the locking lever on a connected spring is regularly designed as a leg spring and connected with a leg to the locking lever.
  • the other leg or generally the spring is acted upon in normal operation by the actuating lever, for the deflection of the locking lever.
  • the locking lever typically has a guide recess for a guide arm engaging the actuating lever therein.
  • the guide arm can be equipped with a spring acting on the pin, which usually passes through the guide recess.
  • the locking lever is a rectangular lever, which is mounted eccentrically on the axle.
  • the rectangular lever may optionally spatially extended and thus be formed with side walls, to provide in this way below the rectangular lever a protected receiving space for on the one hand the spring and on the other hand, the spring interacting with the pin on the guide arm.
  • the center of gravity displacement typically described in the axial extension of the axis above or below said axis is usually implemented by the locking lever is equipped in the axial extension in the direction of the locking mechanism with an extension. As a result, the center of gravity moves into a position in axial extension above the axis of the locking lever. This is of course only an example and not necessarily to understand.
  • the actuating lever is typically a release lever for a pawl as part of the locking mechanism.
  • the locking mechanism is composed of a catch and the already mentioned pawl, which is incident in the closed state of the locking mechanism in a main catch of the catch.
  • the actuating lever or release lever engages behind a stop on the pawl to open the locking mechanism, so that it is pivoted away from the rotary latch.
  • the catch can spring open open and release a previously captured locking pin.
  • the locking lever ensures that the operating lever or release lever is blocked and the pawl can not lift off the catch.
  • the locking lever can still be assigned a stop in the housing.
  • This stop regularly ensures that the locking lever is blocked in case of deceleration forces in an opposite direction.
  • deceleration forces in the opposite direction can occur, for example, when a side impact on the other takes place in comparison with the vehicle side in question.
  • the stop is arranged in total so that the Locking lever can easily perform the pivoting movements described about the axis in normal operation.
  • a motor vehicle door lock which is characterized by special reliability.
  • the invention ensures that in the event of a crash under certain circumstances occurring "bouncing" between the operating lever or release lever and the locking lever is controlled or does not lead to unintentional openings of the locking mechanism during an accident.
  • the locking lever is mounted eccentrically on its axis.
  • the locking lever generates in the event of a crash, the operating lever blocking counter-torque, which catches any bouncing as described.
  • FIG. 1A and 1B the motor vehicle door lock according to the invention in the installed state (FIG. 1A) and with the locking lever removed and the actuating lever (FIG. 1B), FIG.

  • the ratchet 1, 2, 3 is composed of a rotary latch 1 and in the exemplary embodiment, two pawls 2, 3 together.
  • the locking latch 3 assumes the actual blocking function, whereas the pawl 2 is designed as a so-called comfort pawl.
  • the decisive factor is that the locking mechanism 1, 2, 3 located in the main locking position, for example, in FIGS. 1A and 1B, can be opened by lifting the locking pawl 2, 3 away from the rotary latch 1.
  • an actuating lever 4 is provided, which is in the embodiment and not limiting to a release lever 4.
  • actuating lever or release lever 4 and the pawl 2, 3 or their comfort pawl 2 are mounted coaxially in a lock case 5.
  • a bearing pin 6 is provided, which defines the aforementioned common axis.
  • the actuating lever or release lever 4 in the illustration according to FIGS. 1 A and 1 B is pivoted about the bearing mandrel 6 or the axis defined thereby in a clockwise direction. This can be seen in the transition from FIGS. 1A, 1B to FIG. 2.
  • the pawl 2, 3 is lifted off the rotary latch 1.
  • the comfort pawl 2 also makes a clockwise movement about the axis 6 common to the trip lever 4.
  • the pawl 3 is pivoted counterclockwise about its axis 7 so that the pawl 2, 3 releases the catch 1 as a whole, as in the transition from FIG Figs. 1A, 1B for Fig. 2 becomes clear. Normal operation corresponds to this.
  • a locking lever 8 which is rotatably mounted about an axis 9 in the lock case 5.
  • the axis 9 is defined by an associated bearing pin for the locking lever 8.
  • the locking lever 8 ensures that the locking mechanism 2, 3, at least when occurring deceleration forces F predetermined size and direction, for example, in an accident ("crash"), set ineffective.
  • the delay forces F in question are indicated in FIG.
  • the locking lever 8 is mounted eccentrically on its axis 9.
  • the locking lever 8 generates depending on the occurring deceleration forces F a the actuating lever or release lever 4 blocking counter-torque M, which is shown schematically in FIG.
  • This counter-moment M acts on the locking lever 8 in a clockwise direction with respect to its axis 9.
  • the actuating lever or release lever 4 also performs a clockwise movement about its axis 6, as indicated in FIG. 3 by corresponding arrows. This results in a contact area between the locking lever 8 and the actuating lever 4 to opposite movements, as Fig. 3 makes it clear.
  • the stop 12 or the locking lever 8 can follow the actuating lever 4 as a consequence of the counter-torque M generated in the event of a crash. So it does not come to the introductory already discussed "bouncing”. Rather, the invention ensures that the actuating lever 4 permanently applies in the event of a crash to the stop 12 of the locking lever 8 and is blocked in this way. Since the locking lever 8 retains its position due to its inherent inertia in an accident or the occurring deceleration forces F predetermined size and direction, the operating lever or release lever 4 in this case, the locking mechanism 1, 2, 3 does not open.
  • the locking lever 8 has a center of gravity S arranged above its axis 9 in the context of the exemplary embodiment. This is indicated in FIG. 1A.
  • the center of gravity S is in axial extension above the questionable axis 9 of the locking lever 8.
  • another arrangement of the center of gravity S for example, below the axis 9, conceivable. This is not shown.
  • the locking lever 8 is equipped with a connected spring 13, 14.
  • the spring 13, 14 is not limited to a leg spring with two legs 13, 14.
  • the one leg 13 of the spring 13, 14 is fixed to the locking lever 8, whereas on the other leg 14 of the spring 13, 14 of the Operating lever 4 is present.
  • the operating lever 4 has a guide arm 15, which engages with a pin not explicitly shown in a guide recess 16 on the locking lever 8. This allows the pin with the leg 14 of the spring 13, 14 interact.
  • the locking lever 8 is formed as eccentrically mounted on the axis 9 rectangular lever with side walls 17. That is, the locking lever 8 has a spatial extent. The edges of the rectangular lever or blocking lever 8 project downwards in the direction of the lock case 5.
  • the side walls 17 thus define a receiving space for the spring 13, 14 arranged therein.
  • the pin of the actuating lever 4 connected to the guide arm 15 projects through the guide recess 16 into this receiving space. Thereby, the pin in question with the legs 14 of the spring 13, 14 interact, as will be explained in more detail below.
  • Fig. 1A, 1B shows this normal operation, which is associated with that the release lever 4 is pivoted about its axis 6 in a clockwise direction and as a result of the arm 15 on the actuating lever 4 via the pin, the legs 14 of the spring 13, 14 acted upon. Since the other leg 13 of the spring 13, 14 is firmly connected to the locking lever 8, the locking lever 8 is pivoted about its axis 9 in this process. This happens at each scheduled opening operation of the locking mechanism 1, 2, 3 in normal operation, so that at each opening operation, the locking lever 8 is pivoted about its axis 9. As a result, any caking, corrosion, etc. of the locking lever 8 are reliably avoided.
  • the locking lever 8 remains in its position according to FIG. 1A.
  • the actuating lever or release lever 4 is pivoted by the attacking deceleration forces F clockwise about its axis 6, as indicated in FIG. 3.
  • the pivoting movement of the actuating lever or release lever 4 is stopped as soon as the operating lever 4 moves against the stop 12 of the resting locking lever 8.
  • a previously completed (slight) pivotal movement of the release lever 4 about its axis 6 also leads to the fact that the leg 14 of the spring 13, 14 is slightly pivoted, the spring 13, 14 is thus compressed, by the actuating lever. 4
  • the locking lever 8 In order to realize the described eccentric bearing of the locking lever 8 in detail and to ensure that the associated center of gravity S is arranged in the axial extension of the axis 9 above the relevant axis 9 of the locking lever 8, the locking lever 8 typically has an extension 18, in particular recognizes in Fig. 3. By this extension 18, the mass distribution of the locking lever 8 is displaced in the direction of areas above the axis 9, so that as a result of the center of gravity S occupies the specified position above the axis 9.
  • the stop 19 in or on the lock case 5 or a housing is associated with the locking lever 8.
