Definitions
- the invention relates to a motor vehicle door lock, with a locking mechanism, furthermore with a release lever for opening the locking mechanism, and with a locking lever pivotable about an axis, which locks the locking mechanism, at least when deceleration forces of predetermined magnitude and direction occur, for example in the event of an accident ("crash case"). ), invalidates.
- the locking lever In a motor vehicle door lock of the construction described above, as described for example in DE 10 2011 010 816 A1 of the applicant, the locking lever relative to the locking mechanism in normal operation in a blocking position. In the event of a crash, the locking lever blocks the locking mechanism and releases it only for normal operation.
- the locking lever is elastically connected to the release lever by at least one spring. So as soon as the release lever is pivoted to open the locking mechanism, this pivoting movement ensures at the same time that the locking lever is acted upon by the spring. Consequently, the locking lever is taken over the spring. In this way, the locking lever undergoes a movement in normal operation, so that overall the reliability is increased at the same time simple structure.
- the locking lever or the mass barrier realized at this point ensures that high acceleration forces occurring in the event of an accident or a "crashfaH" can not lead to unintentional opening of the locking mechanism and consequently of an associated door lock and thus also of the motor vehicle door. Rather, this crash case leads to the fact that when the described abnormal acceleration forces of the release lever experiences no action. This can be done by blocking an actuating lever mechanism which normally acts on the release lever during normal operation.
- both the locking lever in DE 102011 010 816 A1 and the one corresponding to EP 1 375 794 A2 are each connected to a lock case independently of the locking mechanism and also the actuating lever mechanism. This results in a position of the axis of the locking lever, which is typically defined by a bearing pin, which has a more or less pronounced distance from the operating lever mechanism and also the locking mechanism.
- the structure of the known motor vehicle door locks with the locking lever is designed relatively bulging. This runs contrary to the trend towards increasingly compact designs. This is where the invention starts.
- the invention is based on the technical problem of further developing such a motor vehicle door closure in such a way that, with the functionality remaining unchanged, a particularly compact and inexpensive embodiment is made available.
- a generic motor vehicle door lock in the invention is characterized in that the locking lever is so articulated connected to an actuating lever acting on the release lever, that both levers taken together in normal operation a predetermined Normalbetuschistsweg without mechanical blockade and crash operation one of the normal operation path describe different Crashbetuschistsweg with simultaneous mechanical blockade.
- the locking lever initially experiences, in contrast to the prior art, a bearing on an actuating lever. That is, the locking lever is pivotally connected to the actuating lever and learns in contrast to, for example, the teaching of DE 10 2011 010 816 A1 no rotatable mounting in a lock case.
- the mechanical blockage ensures that the operating lever acting on the release lever does not even reach the release lever or can not mechanically interact with the release lever. As a result, it is ensured in crash mode and on completion of the Crashbetuschistsweges by the two combined levers that the locking experienced no unintentional opening.
- the mechanical blockage on the crash actuation path corresponds to the fact that the actuation lever can not reach the trigger lever at all or can not interact with it. Consequently, the locking mechanism is not opened unintentionally.
- the invention comprises both variants in such a way that the actuating lever directly on the release lever works as well as deviant embodiments in which the actuating lever indirectly with the interposition of one or more elements, the release lever acts on the opening of the locking mechanism.
- the design is such that in normal operation and in a normal operation, the two levers taken together complete the Normalbetuschistsweg. This does not lead to a mechanical blockage of both levers.
- the crash operation corresponds to the fact that the two levers taken together deviate from the normal operation path deviating Crashbet effetistsweg.
- the crash actuation path deviates from the normal actuation travel in that typically the lock lever is blocked.
- the operating lever also experiences a blockage, before it can interact directly or indirectly with the release lever to open the locking mechanism. In this way, an undesirable opening of the locking mechanism is suppressed as described.
- the mechanical blockade of the two combined levers and the locking lever is usually provided by a housing-fixed stop.
- This stop may be arranged on the edge of the lock case or may even be integrated in it.
- This additionally supports the compact design of the motor vehicle door lock according to the invention, because exposed and separately mounted stops are expressly dispensed with, but rather the stop is structurally integrated in the lock case or can be integrated.
- the locking lever is connected in the manner of a toggle lever to the actuating lever.
- the locking lever and the operating lever include a toggle bracket between them.
- the normal operation corresponds to a predetermined knee lever angle
- the crash mode belongs to a comparatively larger (or smaller) knee lever angle. That is, the crash operation is by a characterized by the knee lever angle of normal operation deviating toggle lever angle.
- the deviation of the knee lever angle between the two hingedly interconnected levers automatically causes the assembly of the two levers or the two levers together describe the Crashbetusch and the locking lever moves against the aforementioned stop and can drive.
- the design is usually made in such a way that the normal operation path belongs to a circular arc movement of an outer edge of the blocking lever in comparison to the axis with a predetermined radius.
- the Crashbetusch corresponds to a circular arc movement of the outer edge of the locking lever with the opposite larger (or smaller), at least deviating, radius.
- the outer edge of the locking lever initially describes a circular arc with the axis as the center.
- this axis is an axis of rotation which is defined by a bearing pin receiving the actuating lever. That is, the operating lever is rotatably mounted on the bearing pin in question, wherein the bearing pin is in turn anchored in the lock case.
- the said and thus defined axis also acts as an axis or axis of rotation for the opposite pivotable locking lever.
- the circular arc or the associated circular arc movement has a different radius.
- the design is usually made such that the normal operation path corresponds to the circular arc movement with a given radius, whereas the crash operation path describes a circular arc with a larger radius.
- the Crashbetuschiresweg may also belong to a smaller radius compared to the predetermined radius in the Normalbetrucistsweg.
- the two levers in normal operation perform a forced movement in the joint coupling them. That is, the normal operation corresponds to the fact that the two levers forcibly change the knee lever angle between them. This corresponds to the mentioned forced movement.
- caking, corrosion, etc. are prevented in the coupling joint in question from the outset, because in normal operation, that is, each time the actuating lever is acted upon to open the ratchet, the toggle between the operating lever and the locking lever is inevitably varied.
- a guide slot is provided for the forced movement of the two levers as a rule.
- the locking lever interacts at least at the end of Normalbet2011,sweges with the relevant guide slot.
- the design is generally made so that the locking lever runs at the end of Normalbet2011,sweges and acted upon trigger lever against the guide slot in question and pivots away from the operating lever.
- the included between the two levers knee lever angle is increased and actuates the joint to ensure its long-term reliability.
- the knee lever angle can also be reduced.
- the two levers can be elastically coupled together by a spring.
- the spring generally ensures that together with a stop, the two levers are held in a toggle lever angle belonging to the normal operation to each other, and elastically yielding.
- the invention usually proceeds in such a way that the knee lever angle in question is increased both in the course of the above-described forced movement at the end of the normal operating travel and experiences a comparable increase in the event of a crash.
- the spring is usually a leg spring with two legs.
- one leg is designed as an actuating lever leg and the other leg is designed as a locking lever leg.
- the operating lever leg is applied to the actuating lever or is connected to this.
- the locking lever leg enters into a mechanical connection with the locking lever.
- An additional eyelet or a leg eye of the leg spring connecting the two legs is received by a bearing pin, which provides the articulated support between the locking lever and the actuating lever.
- the normal operation corresponds to a specific knee lever angle, which in the event of a crash undergoes a magnification caused by the attacking deceleration forces in the example case.
- the stop which is preferably arranged or formed on the lock case.
- FIG. 1 shows the motor vehicle door lock according to the invention in section in a perspective view
- FIG. 2A to 2C show the motor vehicle door lock according to FIG. 1 in its rest position (FIG. 2A), in a normal operation (FIG. 2B) and finally in the course of a crash actuation (FIG. 2C).
- a motor vehicle door lock which has an unspecified and shown locking mechanism of catch and pawl.
- On the locking mechanism operates a release lever 1, the movement in a direction indicated in Fig. 1 arrow direction causes the pawl is lifted from the catch in a known manner.
- the catch can spring-open open and a previously captured locking pin release.
- a motor vehicle door can be opened or opened. For this corresponds the so-called normal operation.
- an operating lever 2 is provided in the embodiment.
- the operating lever 2 is part of an unspecified operating lever work.
- the actuating lever 2 can be pivoted about its axis 3 in the direction indicated in FIG. 1 counterclockwise, so that the actuating lever 2 moves with a lever arm 2 'against the release lever 1 and this acts in the direction of arrow to open the locking mechanism.
- the actuating lever 2 To pivot the actuating lever 2 in the counterclockwise direction about its axis 3, the actuating lever 2 is connected regularly and according to the embodiment of an outer door handle 4, which is merely indicated in FIG. Consequently, the actuating lever 2 in the embodiment and not limiting to an external actuating lever. 2
- a locking lever 5 which is connected according to the invention by means of a joint 6 articulated to the operating lever or external operating lever 2.
- the locking lever 5 is acted upon by occurring delay forces of predetermined size and direction, for example in a crash in the direction indicated in FIGS. 1 and 2C by an arrow direction.
- This loading is accompanied by a blockage of the locking lever 5 and also of the actuating lever 2, so that the actuating lever 2 can not act on the release lever 1 to open the locking mechanism, as will be explained in more detail below.
- the locking lever 5 is pivotally connected via the hinge 6 to the actuating lever 2.
- the actuating lever 2 in turn can act on the trigger lever 1.
- Both levers 2, 5 taken together define a toggle lever assembly 2, 5 with the intermediate joint 6, which thus acts as toggle joint 6.
- both levers 2, 5 taken together describe a normal operation path Ri in normal operation.
- the Normalbet2011 tosweg Ri is completed without blockage of the two levers 2, 5.
- the Normalbet2011 tosweg Ri corresponds to a circular arc movement of an outer edge or outer tip 7 of the locking lever 5 in comparison to the axis 3, which acts in this regard as the center of the arc.
- the two levers 2, 5 taken together are mounted together on a bearing pin or bearing pin, which is fixed in a lock case 8 and defines the axis or axis of rotation 3.
- the Normalbet2011 tosweges Ri performs the outer edge 7 of the locking lever 5 in comparison to the said axis 3, the addressed circular arc movement with the radius Ri compared to the center defined by the axis 3.
- the spring 9, 10, 11 is a leg spring 9, 10, 11.
- the leg spring 9, 10, 11 is equipped with a locking lever leg 9, which is connected to the locking lever 5.
- the leg spring 9, 10, 1 1 has an operating lever leg 10, which is connected to the actuating lever 2 or interacts with it.
- the locking lever 5 moves at the end of the Normalbetuschistsweges and already acted triggering 1 for opening the locking mechanism against the relevant guide slot 13.
- the further movement of the locking lever 5 in normal operation that is in a counterclockwise movement of the two levers 2, 5 taken together about their common axis. 3 , now causes the locking lever 5 pivots away from the operating lever 2.
- the associated knee lever angle ⁇ increases and corresponds to a knee lever angle ⁇ with ⁇ ⁇ . This is possible because, in this connection, the spring 2, 5 coupling the two levers 9, 10, 1 1 yields elastically and, moreover, the stop 14 on the locking lever 5 is released from the stop 12 on the actuating lever 2. This can be seen in Fig.
- the crash-actuating path R2 also corresponds to a circular-arc movement, which again performs the outer edge 7 of the locking lever 5 in comparison with the axis 3 representing the center point.
- the crash operation path R2 is equipped with a comparatively larger radius R2. That is, it applies:
- the toggle lever assembly 2, 5 or the levers 2, 5 taken together can not (more) act on the trigger lever 1. Because the outer edge 7 of the locking lever 5 moves against a stop 15, which is formed on the lock case 8 or connected to the lock case 8.
- the two levers 2, 5 are spread in terms of their knee lever, so that the knee lever angle of ß increased.
- This spreading of the two levers 2, 5 has the consequence that the outer edge 7 of the locking lever 5 - caused by the attacking deceleration forces - as it moves with respect to the lock case 8 "out” and thereby the outer edge 7 against the outer edge the lock case 8 provided stop 15 moves. This happens even before the operating lever 2 can interact with the release lever 1. Consequently, the ratchet remains unaffected and can not open unintentionally.
