Definitions
- the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and a pawl, and with a release lever for acting on the pawl and for opening the locking mechanism.
- motor vehicle lock is to be understood broadly in this case and applies not only to motor vehicle door locks, but also, for example, to motor vehicle locks in connection with the locking of seats, flaps, etc.
- motor vehicle locks are nowadays and increasingly operated by electric motors. This means that special comfort applications can be implemented and the operating forces are low.
- the release lever is composed of the pawl release lever and the confirmation release lever. While the pawl release lever primarily ensures that the pawl can be lifted from its latching engagement with the rotary latch when the locking mechanism is closed, a pivoting movement is usually entered into the release lever as such via the actuation release lever. In terms of their basic concept, both levers are designed to be functionally and mechanically separate.
- the two levers are coupled to one another in a rotationally fixed manner. If, on the other hand, the pin is moved out of the recess, a relative movement between the two levers is possible and conceivable, as will be explained in more detail below with reference to the description of the figures. As a result of this relative movement, any blockages in the release lever can be easily solved, for example by a motor or electric motor drive or an actuating lever or other blockages. All that is required for this is that the coupling member decouples the two levers from each other, so that a relative movement between the two levers is then possible.
- the pawl spring mentioned can ensure that the pawl goes into its basic position and can also go over, in which the rotary latch then is held during the transition to its closed position.
- the pawl spring not only acts on the pawl accordingly, but is also able, according to the invention, to be able to move the pawl release lever relative to the actuation release lever if, for example, the actuation release lever should be blocked.
- the thrust element for acting on the coupling member is advantageously a worm wheel. That is, for this purpose, the said worm wheel or thrust element regularly has a circumferential eccentric or an arc contour, with the help of which the coupling member is transferred from its coupled position in the basic position to the decoupled position.
- a spring may act on the coupling member, which biases the coupling member in the direction of its position coupling the two levers.
- the invention is based on the knowledge that the coupling member is typically designed at the same level as the two levers, which are also mounted on the same axis.
- the stop edge of the coupling member can describe a plane that is perpendicular to this plane.
- the axis for the thrust element is usually also arranged in this plane, so that rotations around the axis of the thrust element pivot the corresponding arc contour, which in turn moves the coupling member from its “coupled” position in the basic position to the “uncoupled” position via the stop edge Transferred to the two levers through a linear adjustment process.
- FIG. 2 shows the object according to FIG. 1 during an electromotive opening process
- Fig. 4 shows the motor vehicle lock according to Fig. 3 during a reset movement in the decoupled state.
- the release lever 3, 4 is designed in two parts.
- the two-part release lever 3, 4 is initially composed of the pawl release lever 3, which acts on the pawl 2 and has already been mentioned, and an additional actuation release lever 4.
- the actuation trigger lever 4 can in turn interact with an actuation lever (not expressly shown), an electric motor drive or both.
- said actuating lever and/or the electric motor drive can also act on the pawl release lever 3 in order to achieve the overall two-part release lever 3, 4 in the course of opening the locking mechanism 1, 2 in the clockwise direction indicated in FIG. 1 to pivot about the axis of rotation 5.
- Fig. 1 the motor vehicle lock is shown in a basic position.
- the release lever 3, 4 is acted upon for an opening process. This corresponds to the fact that the release lever 3, 4 rotates about its axis of rotation 5 in the Fig. 1 is acted upon in the clockwise direction indicated.
- the stop edge 6a of the coupling member 6 is opposite the thrust element or worm wheel 9. Both the pawl release lever 3 and the actuation release lever 4 are rotatably coupled to one another via the coupling member 6.
- the coupling member or the coupling slide 6 can then be moved linearly via the thrust element or worm wheel 9 during the transition from FIG. 2 to FIG. 3. This is previously in a position that mechanically couples the two levers 3, 4 to one another. As a result, both levers 3, 4 are pivoted synchronously about the common axis 5 during the opening process of the release lever 3, 4.
- the pawl 2 cannot be transferred to its basic position using a pawl spring, not shown. This can be detected sensorically using the sensor or pawl switch already described in the introduction and not expressly shown.
- a control unit querying the sensor or pawl switch in question may then ensure that the thrust element 9 is acted upon, in such a way that the coupling member 6 moves to the “right” in the exemplary embodiment according to FIG. 2 and indicated by the arrow there becomes.
- the two opposing pins 7 leave their associated recesses 8, so that subsequently and in accordance with the functional illustration in FIG. 3, the two levers 3, 4 are decoupled from one another. This can lead to a relative movement between the Both levers 3, 4 come, as can be seen by comparing Figures 2 and 3.
- the pawl release lever 3 is pivoted (slightly) in the counterclockwise direction around the axis of rotation 5 during the transition from FIG. 2 to FIG. 3, as an arrow in FIG. 3 indicates.
- This is ensured by the pawl spring assigned to the pawl 2 and not expressly shown.
- the pawl 2 assumes its basic position comparable to the position in FIG.
- the actuation release lever 4 can also follow the pivoting movement of the pawl release lever 3, as can be seen in the transition from FIG. 3 to FIG. 4.
- the coupling member 6 can be returned to its starting position as shown in FIG. A spring (not expressly shown) which biases the coupling member 6 towards this basic position may ensure this.
