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 intended to provide unintentional opening in the event of a crash in the case of a structurally simplified design. Also, a permanent blockage 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 is known, which is provided with a lockable by a pawl in a closed position and after a caused by actuation of a pawl actuating member pivoting the pawl from this blocking position in a release position movable catch.
• this document proposes that the catch is blocked in its blocking position by a vorlösbaren upon actuation of the pawl actuator and blocking lever to be designated blocking member.
• the locking lever blocks both in undisturbed normal operation and in the event of a crash, the catch and releases it only for deflected normal operation.
• 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 spring engages the blocking arm of the locking lever and the inertial forces of the locking lever occurring in the event of a crash 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. In contrast, accidents are usually associated with significantly greater acceleration or deceleration. In this case, the following is spoken of abnormal acceleration processes or abnormal acceleration forces or a crash event or accident. Now occurs such an accident or crash, so according to the invention 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 rotary latch in the direction of its blocking position. In other words, take the locking lever, the catch and consequently also the locking mechanism in normal operation as well as in the event of a crash, respectively, the blocking position.
• the locking lever Only when opening in normal operation, the locking lever allows the release position of the catch and thus the locking mechanism, so there are thus the locking lever, the catch 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 Rotary latch remains in its blocking 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.
• the blocking pawl and of course the pawl 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 catch, at least in such a way that the catch 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 engages the blocking arm of the locking 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 may have a blocking contour interacting with the catch, a cam, a formation, etc. In this case, any game between the locking lever and the catch is such that the process described proceeds without problems.
• the locking lever interacts according to the invention with the rotary latch.
• the pawl in turn attacks the catch of the locking mechanism.
• the pawl may be mounted on the operating lever mechanism.
• the rotary latch interacts with the locking lever. Only then, when the locking lever assumes its release position, the catch can come free from its closed position.
• 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 catch 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 more or less significantly exceed any coupling forces to the operating lever mechanism.
• 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.
• For the return movement of the locking lever provides a second spring, which moves it into its blocking position.
• a motor vehicle door lock is equipped with a catch of a catch of a locking pawl and a pawl.
• the locking mechanism is stored in a lock case.
• actuating lever mechanism which is composed of a release lever and an attached further lever or several other levers.
• the release lever In order to open the locking mechanism in the closed state, the release lever must be rotated clockwise about its axis by the actuating lever mechanism. Such a rotation of the release lever causes the release lever engages with an edge on a pin of the locking pawl.
• the clockwise movement of the release lever during this process corresponds to the fact that the blocking pawl performs a counterclockwise movement about its axis.
• the locking pawl releases the pawl and unlocks the previously caught catch.
• the catch is spring-assisted from its illustrated closed position by clockwise rotation in an open position and there is a previously captured locking pin free.
• the locking pin is connected to a motor vehicle door, which is also released during this process and can be opened.
• the pawl ensures that the locking mechanism is held in the closed position.
• the locking pawl thus acts - if you will - as an additional backup of the catch, in addition to the pawl.
• the control of the catch from the blocking position to the release position (and back) is carried out according to the invention by means of a release lever, wherein a locking lever is transferred from its blocking position into a release position.
• the locking lever is designed as pivotable about an axis pivoting lever.
• the locking lever is designed as a two-arm lever and has a Blockadearm and a balance arm. The blockage arm interacts with the already mentioned rotary latch.
• the locking lever is mounted with its axis together with the locking mechanism in the lock case.
• the respective axes of one hand, the rotary latch, the blocking pawl and on the other hand, the pawl and the release lever and finally the locking lever are each arranged parallel to each other. All axes are each substantially perpendicular to a ground plane of the lock case and are each anchored in the lock case.
• the locking lever is coupled to the operating lever mechanism.
• an elastic coupling is realized in the form of a spring.
• the spring in the embodiment connects the release lever with the locking lever.
• the spring acts on the blocking arm of the blocking lever.
• the locking lever is equipped with a cam or a molding, which interacts with a counter-element on the rotary latch.
• the locking lever has on its Blockadearm via a recess. In this recess engages a cam arranged on the catch.
• the locking lever performs a counterclockwise sense movement about its axis.
• the locking lever takes its release position.
• This counterclockwise sense movement of the locking lever about its axis is caused by the fact that in normal operation, the release lever is pivoted about its axis in a clockwise direction to open the locking mechanism.
• the operating lever mechanism may be acted upon by pulling a door handle, for example, an inner door handle or outer door handle. This indicates an arrow.
• the blocking pawl Since the process described and the clockwise rotation of the release lever simultaneously applied by means of the stop edge of the pin on the blocking pawl, the blocking pawl is operated synchronously and the pawl is lifted automatically or via a further contour on the trigger from the catch. At the end of this process, the catch is free and can of the Turn closed position clockwise about its axis and release the previously captured locking pin.
• the locking lever remains in its blocking position and ensures that the catch for the locking mechanism is likewise acted upon in the direction of its blocking position. That is, the locking lever remains at rest and as a result thereof interacting with the locking lever rotary latch, both levers unchanged maintain their blocking position and thereby hold the catch in the closed state. This position of normal operation is maintained even in the event of a crash.
• the mass inertia of the locking lever ensures that it does not come in the event of a crash to a relative movement of the locking lever, so that the two locking lever and catch relative to each other remain at rest.
• locking lever acts on the catch of a locking mechanism which is executed without blocking pawl in the form described, wherein the release lever acts directly on the pawl.
