Definitions

• the invention relates to a motor vehicle door lock, with a locking mechanism, also with at least one actuating lever, and with a locking lever.
• the locking lever can be coupled directly to the actuating lever, at least in order to assume its locking position. This happens in the course of a first stroke of the actuating lever.
• the associated motor vehicle door lock or its locking mechanism can now be opened as part of a second stroke.
• Such a two-stroke actuation has proven itself, even in connection with an optional child safety and / or anti-theft device. However, at this point it is necessary to first move the anti-theft device or the child safety device into its "off" position to unlock the locking mechanism. It is expensive.
• both two-stroke operations and single-stroke operations are described in the prior art.
• an associated locking mechanism or the motor vehicle door lock is first unlocked in the course of the first stroke and then opened during the second stroke.
• the single stroke actuation ensures that both unlocking and opening are carried out in the course of a single stroke.
• Both approaches are implemented with different and sometimes complicated lever mechanisms. It is expensive. This is where the invention comes in.
• the invention is based on the technical problem of developing a motor vehicle door lock of the design described at the outset in such a way that, with a very simple construction, both problem-free two-stroke actuation and one-stroke actuation to open the locking mechanism are possible.
• a generic motor vehicle door lock is characterized in that the actuating lever has a first partial lever and a second partial lever, and in that the lock locking lever controls a coupling element, which optionally connects the two partial levers with each other.
• DE patent application 101 64 484 also has a divided actuating lever and a coupling element which optionally connects the two partial levers to one another.
• the locking lever controls the coupling element
• the coupling lever or the coupling element is acted upon by a security device, which can be an anti-theft device and / or a child security device.
• the present innovation thus generalizes the use of an actuating lever with a first partial lever and a second partial lever, which are optionally connected to one another with the aid of the coupling element, in such a way that the mostly already existing locking lever or a comparable locking element is now used to control the coupling element is used.
• An additional security device in the form of a child security device and / or an anti-theft device is accordingly not necessary.
• a safety device can of course be used, as will be described in more detail below.
• the inside handle lever may be connected to an inside door handle be while the internal actuation release lever works on the locking mechanism or a release lever usually provided there. This means that the actuating lever is regularly, but not restrictively, the inner actuating lever.
• the locking lever has a control pin for a driving contour on the coupling element.
• both of the aforementioned elements ensure that the coupling element connects the two partial levers of the actuating lever to one another or not.
• the control pin of the locking lever can also act on one leg of a leg spring which is arranged on the coupling element.
• the coupling element is largely a coupling lever, which is pivotably mounted on the other partial lever of the inner operating lever.
• This other partial lever is mostly the inner actuation release lever.
• the clutch element or the clutch lever engages in a recess in one of the partial levers, which is the inner actuation handle lever.
• the coupling element itself has a receptacle for this one partial lever or the inside actuation lever.
• the actuating lever pivots the locking lever in the course of a first stroke when the locking lever is in the locking position so that it, that is to say the locking lever, engages the coupling element with the two partial levers.
• the locking lever can of course also provide the required engagement of the coupling element with the two partial levers independently of the actuating lever, namely by the motor being controlled accordingly.
• the locking mechanism is then opened as part of a second stroke of the actuating lever.
• the locking lever has the control pin for the contour or the leg spring on the coupling element, one-stroke actuation of the actuating lever can also be used instead of the two-stroke actuation described.
• control pin is not attached to the locking lever, so that when the actuating lever is triggered for the first time, the coupling element directly couples the inner actuating handle lever to the inner actuating trigger lever.
• Such a single-stroke actuation is recommended, for example, when the motor vehicle door locks are automatically locked while driving in a motor vehicle. It may then be desirable for a vehicle occupant to be able to unlock and simultaneously open the motor vehicle door lock with only a single stroke.
• situations are conceivable in which the motor vehicle door locks are locked from the inside manually or at the push of a button while driving or even when stationary. In order to distinguish this state from the fact that no locking has been carried out, one will work with a two-stroke actuation in the former case, whereas with unlocked motor vehicle door locks, of course, only a one-stroke actuation is required to open the locking mechanism.
• the theory of the invention opens up the possibility of either one-stroke or two-stroke actuation depending on the customer's wishes and the Requirements to be able to open the locking mechanism or the motor vehicle door lock. To distinguish between these two basic procedures, it is only necessary to equip the locking lever with the control pin or not.
• the coupling element can be acted upon by a child safety device and / or anti-theft device.
• the "childproof lock on” or “anti-theft lock on” position corresponds to the fact that the coupling element is in the pivoted-out position, and consequently the two partial levers of the actuating lever are not connected to one another.
• the coupling element only connects the two partial levers of the actuating lever to one another when both child safety and theft protection take their position “off”. This includes moving the locking lever to the "unlocked” position.
• a motor vehicle door lock is made available which not only impresses with a particularly simple and compact structure when the actuating lever is actuated two-stroke, but can also be converted in the sense of a single-stroke override. This is achieved in a simple manner in that the control pin on the locking lever is omitted, so that the coupling element engages immediately in the course of one stroke in order to mechanically connect the two relevant partial levers to one another.
• the motor vehicle door lock described can also optionally be equipped with an anti-theft and child safety function combine. This is where the main advantages can be seen.
• the basic structure of the motor vehicle door lock in question includes a locking mechanism 1, 2 consisting of a rotary latch 1 and pawl 2, an actuating lever 3a, 3b and two locking levers 4, 5.
• the two locking levers 4, 5 are coupled to one another by a pin 6 of the locking lever 5 engages in an elongated hole 7 of the inner locking lever or driving lever 4.
• only one locking lever 4, 5 is also possible.
• a motor or electric motor 8 which is only indicated in FIG. 3, is capable of locking lever 5 at the transition from FIG. 1 to FIG. 2 as indicated in FIG To turn clockwise, so that the inner locking lever 4 or driving lever rotates counterclockwise about its axis 9 by the engagement of the pin 6 in the recess or the elongated hole 7.
• the two partial levers 3a, 3b of the actuating lever 3a, 3b composed thereof, which in the exemplary embodiment is an internal actuating lever 3a, 3b, are mounted.
• One of the partial levers 3a is designed as an internal actuation handle lever 3a, while the other partial lever 3b represents an internal actuation release lever 3b.
• the described motor movement of the locking lever 5 and consequently of the inner locking lever 4 has the consequence that a pin 10 located on the inner locking lever 4 interacts either with a contour 11 on a coupling element 12 or with a leg of a leg spring 22 arranged on the coupling element 12 ,
• the coupling element 12 designed as a coupling lever 12 is capable of mechanically coupling the two partial levers 3a, 3b to one another or not.
• the coupling element or the clutch lever 12 is pivotally mounted on the other partial lever 3b or the inner actuation release lever 3b and has a receptacle 13 for the one partial lever 3a or the inner actuation handle lever 3a.
• the coupling element 12 is in one overall Recess 14 of one of the partial levers 3a and the inner actuating handle lever 3a is arranged. If, according to a first embodiment variant according to FIGS. 1 and 2, the internal locking lever 4 executes the counterclockwise movement about the axis 9 during the transition from FIG. 1 to FIG. 2, the pin sliding along the contour or driving contour 11 ensures 10 of the inner locking lever 4 for the coupling element 12 to be pivoted out through an opening area 11a of the contour. Because with the described counterclockwise movement of the inner locking lever 4, the pin 10 moves, as it were, "upwards" in FIGS. 1 and 2.
• a leg spring 22 is arranged on the clutch lever 12, in particular on a mandrel 21, which at the same time also coincides with the axis of rotation of the clutch lever 12 mounted on the inner actuation lever 3b, which spring spring connects to the control pin 10 of the Locking lever 4 corresponds.
• Control pin 10 a rotary movement according to FIGS. 1 and 2 in the counterclockwise direction, the control pin 10 shifts the leg 23 of the leg spring 22 according to FIG. 5 with the consequence that the coupling lever 12 is displaced out of its pivoted-out position via the leg spring 22.
• control pin 10 of the locking lever 4 is arranged in an area between the two legs 23, 24 of the leg spring 22, the control pin 10 being shown in FIG.
• the pivoted-out coupling lever or the coupling element 12 now enables the two partial levers 3a, 3b to be mechanically connected to one another with the aid of the coupling element 12 after the end of a first actuation stroke. This is shown in FIG. 2 and in FIG. 5.
• the locking lever 4, 5 or the internal locking lever 4 has ensured the control of the coupling element 12, namely by the interaction of its pin 10 with either the contour 11 or the leg spring 22 on the coupling element 12.
• the first stroke of the actuating lever 3a, 3b or of the inner actuating handle lever 3a is brought about by a pulling movement on an inner door handle 15 which is connected to the relevant inner actuating handle lever 3a via any connecting element.
• the inner actuation release lever 3b can work on a release lever 16 which has a bevel 17 is equipped, against which a nose 18 of the inner actuation release lever 3b rests.
• the internal actuation handle lever 3a is moved back spring-assisted into the position according to FIG. 1 after the pulling movement corresponding to the first stroke.
• this pre gear overlaps the receptacle 13 of the coupling element 12 the inner actuation release lever 3b, so that the coupling element 12 comes to rest in the recess 14 by connecting the partial levers 3a, 3b (cf. FIG. 3).
• the nose 18 is able, in the course of a second stroke of the actuating lever 3a, 3b, to actuate the release lever 16 such that the locking mechanism 1, 2 is opened.
• the described motorized pivoting of the inner locking lever 4 counterclockwise about its axis 9 corresponds, for example, to a central locking function. Because in the "locked" position according to FIG. 1, pulling movements on the inner door handle 15 result in the actuating lever 3a, 3b starting with a cantilever 19 against a stop 20 of the locking lever 5 and this, that is to say the locking lever 5, in its position " unlocked “transferred. - Of course, the inner locking lever 4 can not only be pivoted by motor, but also manually, but this is not shown.
• the second stroke of the actuating lever 3a, 3b then ensures that the now continuous mechanical connection from the inner door handle 15 to the release lever 16 makes it possible for the locking mechanism 1, 2 to be opened when the inner door handle 15 is pulled.
• the described vehicle door lock Kra also allows a lifting operation of the locking mechanism 1, 2. For this purpose, this one stroke not only ensures unlocking of the motor vehicle door lock, but also opening it at the same time.
• the control pin 10 is not attached to the locking lever or inner locking lever 5.
• the coupling element 12 falls directly into the recess 14 when the internal actuation lever 3a is acted upon.
• the boom 19 ensures that the internal locking lever 4 assumes its "unlocked” position. Due to the mechanical coupling of the the two partial levers 3a, 3b, the locking mechanism 1, 2 can be opened directly in the course of this stroke of the interior actuating handle lever 3a.
• the motor vehicle door lock therefore does not assume the intermediate position according to FIG. 2 in this case during the transition from FIG. 1 to FIG. 3.
