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 blocking the actuating lever at predetermined vehicle accelerations, which thus prevents unintentional opening of the locking mechanism.
- a motor vehicle door lock of the design described above is in the context of DE 101 30 260 A1 described.
- the vehicle accelerations are usually those in the transverse direction of the motor vehicle (Y-direction), which act mainly in a side impact on the motor vehicle door lock and of course the body as a whole. If these vehicle accelerations exceed a certain predetermined threshold value, then the locking lever ensures that the at least one actuating lever is blocked. Consequently, the locking mechanism can not (more) be triggered.
- the locking lever If the vehicle acceleration (in the transverse direction) falls below the threshold value, then the locking lever usually returns to its untripped original position, so that the locking mechanism can be (re) opened. As a result, it is achieved in detail that the motor vehicle door lock and thus the associated motor vehicle door is not opened unintentionally during the accident. Before and after course, a deterioration of the door opening should not be given. That is, the locking lever only takes during the occurring vehicle accelerations above the threshold of its triggered position, which corresponds to the blockage of the actuating lever.
- the invention is based on the technical problem of developing a motor vehicle door lock of the above-described design so that the locking lever not only perfectly takes over its blocking function for the operating lever, but additionally functional impairment of the operating lever can be reliably excluded in normal operation.
- a generic motor vehicle door lock is characterized in that the triggered locking lever slides along beaufschlagtem operating lever on a guide surface with an end stop, so that the operating lever is blocked only after sweeping an adjustable actuating travel.
- the locking lever has a boom which slides in its untriggered position along the guide surface.
- the locking lever may have a stop surface which is guided in its triggered position on the guide surface or also slides along. That is, in the normal case and not triggered locking lever, the boom ensures that the usually stored on the operating lever locking lever maintains this normal position throughout. Indifferent layers or operating states of the locking lever can thus be reliably excluded.
- the locking lever is transferred when a certain threshold of these vehicle accelerations is exceeded in its triggered position. This has the consequence that the boom away from the guide surface and rather slides along the stop surface of the locking lever on this guide surface. In both cases, that is, when triggered and not triggered locking lever, consequently, the operating lever and with it the locking lever mounted thereon can be properly move, the locking lever is positioned consistently. This looks in the untriggered position of the locking lever in detail so that the locking lever is positioned at least by means of the boom and an additional stop on the operating lever.
- the locking lever has in the region of its bearing axis on the actuating lever via a spring which biases him in the direction of the stop on the actuating lever, it is clear that as it is given a three-point positioning of the locking lever in normal operation. For this, ensure the bearing axis of the locking lever on the operating lever, the stop on the actuating lever on which the locking lever spring-applied and finally the boom on the locking lever, which slides on movements of the actuating lever and consequently the entrained locking lever on the usually housing-fixed guide surface.
- the locking lever can not move into any intermediate position or an indifferent operating state in normal operation.
- the locking lever slides with its stop surface along the guide surface. This also ensures proper positioning.
- the forces associated with the vehicle accelerations must first overcome the force of the spring on the locking lever. The design is made so that this is the case only in a (side) impact. If the corresponding vehicle acceleration fails or falls below the threshold value given by the force of the spring, then the locking lever returns to its normal position.
- the guide surface with end stop is - as already stated - usually fixed to the housing and may be connected to an already existing motor vehicle door lock housing or a part thereof.
- a molded-on design has proven itself. Because both the actuating lever and the locking lever are regularly designed as a flat lever and lie in directly superimposed planes, the guide surface is above the operating lever and is as Arch surface formed. It is understood that the relevant arc surface is formed with the same level as the plane spanned by the locking lever level.
- the stop in conjunction with the guide surface on a triangular receptacle for a correspondingly shaped blocking tooth on the locking lever.
- This triangular recording is achieved by the blocking tooth when acted upon actuating lever only after sweeping the adjustable actuating travel. Its shape makes it possible that the blocking tooth can easily engage in the triangle recording - guided along the guide surface - and swung out of this triangle recording feather-assisted in the absence of vehicle acceleration or falling below the threshold.
- the locking lever is - as already shown - mounted on the actuating lever, wherein the spanned by two levers planes are arranged substantially parallel to each other. In addition, a complete coverage takes place. That is, the locking lever is located in vertical projection both in its untripped and its released position completely on the operating lever. This is not mandatory.
- a motor vehicle door lock which is characterized by a defined position of the locking lever, in particular in normal operation.
- the locking lever can therefore not be transferred to any intermediate positions that could affect its subsequent function in a possible side impact.
- the reliability is thus significantly increased over prior art embodiments.
- FIG. 1 shows a motor vehicle door lock according to the invention, reduced to the essential components.
- a locking mechanism 1, 2 which is composed as usual of a rotary latch 1 and a pawl 2.
- On the ratchet works an operating lever 3, which is carried out in the context of the example and not limiting as an external operating lever 3.
- the actuating lever 3 is connected to a handle 3 ', which acts on it, so that in the unlocked state of the motor vehicle door lock, the locking mechanism 1, 2 can be opened.
- a release lever 4 may be interposed, but this is not mandatory.
- the motor vehicle door lock additionally has a locking lever 5.
- the locking lever 5 is mounted on the actuating lever 3, to which an axle 6 is used.
- the locking lever 5 but also be carried out independently of the operating lever 3, as long as it is only ensured that the locking lever 5 ensures at predetermined vehicle accelerations F that the operating lever 3 is blocked.
- the locking lever 5 is, however, mounted on the actuating lever 3, in a plane parallel thereto compared to the plane spanned by the operating lever 3 level. It comes in the context of the presentation to a complete coverage. That is, in vertical position or plan view, the surface of the locking lever 5 moves in all its functional positions always within the surface of the actuating lever. 3
- the locking lever 5 can assume two basic positions relative to the actuating lever 3. Shown drawn through is its normal position, which corresponds to the fact that a side impact does not take place. That is, indicated by an arrow vehicle accelerations F in vehicle transverse or Y direction does not exceed the predetermined threshold. This threshold depends on the force or constant of a spring 9, which acts on the locking lever 5 in the direction of a stop 10 in the counterclockwise direction.
- the spring 9 is designed as a spiral spring and surrounds the axis 6, with which the locking lever 5 is mounted on the actuating lever 3.
- the indicated vehicle acceleration F corresponds to an opposing inertial force of the locking lever 5, which leads to an adjustment of the locking lever 5 when the counterforce applied by the spring 9 is overcome. Then the locking lever 9 moves from its solid in its dash-dotted lines indicated triggered position. At the same time proposes the locking lever 5 to the guide surface 7 with the end stop 8, with its stop surface 11. Between these two positions (shown in solid lines and dashed lines), the locking lever 5 can reciprocate.
- the locking lever 5 undergoes a three-point determination in its normally drawn solid position.
- This three-point determination is realized on the one hand by the axis 6 and on the other hand the stop 10 and finally a boom 12 on the locking lever 5.
- the spring 9 ensures that the locking lever 5 rests against the stop 10.
- the boom 12 is at non-triggered position of the locking lever 5 on the guide surface 7 and slides along this, when the operating lever 3 and consequently the locking lever 5 are moved.
- the illustrated guide surface 7 with the end stop 8 is fixed to the housing and integrally formed on a non-illustrated motor vehicle housing.
- the guide surface 7 is located above the actuating lever 3 and is placed in approximately the same plane with the also arranged above the operating lever 3 locking lever 5.
- In the guide surface 7 is an arcuate surface, so that the actuating lever 3 including locking lever 5 can perform in its normal position indicated pivoting movements about an axis 13 in a conventional operation (see the double arrow).
- the stop or end stop 8 in conjunction with the guide surface 7, forms a triangular receptacle 14 for a correspondingly shaped blocking tooth 15 on the blocking lever 5.
