Definitions
- Motor vehicle lock in particular motor vehicle door lock
- 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 also with at least one operating lever and one release lever, which engage via a coupling element in its at least one engaged position and disengaged in its disengaged position Can be brought into engagement, and with at least one inertia lever for acting on the coupling element in its disengaged position at least in the event of a crash.
- the actuating lever consequently works on the release lever when the coupling element is in the engaged state.
- a locking mechanism that is generally in the closed state can be opened via the release lever.
- the release lever acts on a pawl as part of the locking mechanism, which is thereby lifted from its latching engagement with an associated rotary latch.
- the actuation lever does not act because an associated actuation lever chain between the actuation lever and the release lever is interrupted.
- the locking mechanism located in the closed state remains in its closed functional position.
- the mass inertia lever now ensures that the clutch element located in its engaged position is disengaged, at least in the event of a crash.
- the event of a crash corresponds to high accelerations or transverse accelerations of generally 5g and more, so that an unintentional opening of the locking mechanism is thereby avoided.
- an associated motor vehicle door remains closed and safety systems usually located in the motor vehicle door, such as side impact protection or side airbags, can develop their full effect to protect the motor vehicle occupants.
- a control lever is provided in addition to the inertia lever, which interacts with the inertia lever.
- the control lever is guided in a control contour of the mass inertia lever. This is intended to provide a defined control of the clutch behavior.
- the motor vehicle lock and in particular the motor vehicle door lock can be opened without any problems. This should be possible both from the inside for possibly uninjured or slightly injured occupants as well as from the outside for rescue personnel. In practice, this is often made more difficult by the fact that individual or all motor vehicle doors have been locked before the crash, so that any problems can arise from this.
- a crash safety device for a motor vehicle door which acts practically exclusively on the outside door handle. This is because a holder is provided for connecting a pull element for actuating the motor vehicle lock using a door handle. The tension element is blocked with the help of a crash element.
- the further prior art according to DE 10 2016 124 941 A1 describes, among other things, a crash lock with a locking device and a release device.
- the release device is equipped with a mechanical timer. This allows a movable component of a motor vehicle, and in particular a motor vehicle door, to be opened after a predetermined time. This is a period of 1 to 5 seconds.
- the invention is based on the technical problem of further developing such a motor vehicle lock and in particular a motor vehicle door lock in such a way that a particularly functional structure is made available, which allows and provides easy opening from the inside or from the outside after a crash .
- a generic motor vehicle lock and in particular a motor vehicle door lock is characterized within the scope of the invention in that the coupling element can be controlled into a first and a second engaged position depending on the configuration of the operating lever.
- the coupling element can be transferred into at least two different engaged positions, namely the first engaged position and the second engaged position.
- the actuating lever is an internal actuating lever
- the clutch element is controlled into the first engaged position in the example.
- This first engaged position may correspond to the inside actuating lever in question continuously engaging the release lever.
- the invention is based on the knowledge that in the event of a crash, forces act almost predominantly on an outside door handle and consequently on an associated outside operating lever, while the inside door handle and consequently also the inside operating lever remain unaffected.
- the first engaged position can reflect this situation, namely that the inside door handle and with it the inside actuating lever - even in the event of a crash - are continuously engaged with the release lever, so that motor vehicle occupants can easily free themselves from the associated motor vehicle after such an accident.
- the procedure with regard to the outside actuating lever is such that this, like the associated outside door handle, does not engage with the release lever in the event of a crash. That is, in the event of a crash, the clutch element that is in the first engaged position is acted upon with the aid of the mass inertia lever in such a way that the outside actuating lever is disengaged from the release lever.
- both an internal actuating lever and an external actuating lever are implemented.
- the design is usually such that in the first engaged position of the clutch element and when the clutch element is acted upon by the mass inertia lever, only the external actuating lever is disengaged from the release lever.
- the inside actuating lever is still in engagement with the release lever in the first engaged position of the clutch element and when the clutch element is acted upon by the mass inertia lever. That is to say, the pivoting movement of the mass inertia lever that is associated with the crash and is typically observed is idle in the first engaged position of the coupling element in relation to the inside actuating lever.
- the coupling element is acted upon in the first engaged position with the aid of the mass inertia lever in such a way that the external actuating lever is disengaged from the release lever.
- the second engaged position of the clutch element means that when the clutch element is acted upon by the mass inertia lever, neither the outer actuation lever nor the inner actuation lever are disengaged from the release lever because they are already engaged in the second clutched position of the clutch element assume or have assumed such a disengaged position. That is, in the second engaged position of the coupling element, in the event of a crash, the mass inertia lever has an idle stroke in relation to the coupling element.
- a locking element is generally provided to actuate the coupling element into the first and second engaged position.
- the first engaged position corresponds to the "unlocked” position.
- both the inside actuating lever and the outside actuating lever are mechanically connected to the release lever.
- the inside door handle and the outside door handle So that in this first engaged position and the "unlocked" position of the coupling element in the event of a crash, the outside door handle does not unintentionally correspond to an opening of the associated motor vehicle door, in this first coupled position and when the coupling element is acted upon by the inertia lever, the inertia lever ensures that only the outside actuating lever disengaged from the release lever.
- the inside door handle and with it the inside actuating lever on the other hand, remain unchanged in engagement with the release lever.
- the second engaged position of the coupling element corresponds to the “locked” position of the locking element.
- both the inside operating lever and the outside operating lever are disengaged from the release lever.
- the locking element that controls the coupling element is usually acted upon by a motor and/or manually.
- the locking element is typically equipped with a ring gear and designed as an actuating cam for the coupling element.
- This actuating cam has the said ring gear at one end and is articulated at the other end to the coupling element.
- the coupling element is mounted in a linearly displaceable manner on the release lever.
- the coupling element advantageously has an external actuating lever contour and an internal actuating lever contour.
- the external actuating lever contour is usually realized on the head side of the coupling element.
- the inside actuating lever contour is a pin that connects to the inside of the outside actuating lever contour. To interact with the inside actuating lever, the pin can be gripped from behind by a chamfer on the inside actuating lever.
- the first engaged position of the coupling element now corresponds to the fact that the fold on the inside actuating lever can work on the pin.
- the external operating lever is also able to move against the head-side external operating lever contour. If a crash then occurs, the clutch element that is in the first engaged position is disengaged with the aid of the mass inertia lever. As a result, the outside operating lever contour is shifted out of the area of influence of the outside operating lever, whereas the pin on the coupling element can interact unchanged with the chamfer on the inside operating lever. In the second engaged position of the coupling element, neither the contour of the outside operating lever nor the pin are in the area of action of the outside operating lever or the inside operating lever.
- a motor vehicle lock and in particular a motor vehicle door lock is made available, which works in a particularly functional manner.
- the locking element can be used to control and specify whether, in the event of a crash, the mass inertia lever only applies pressure to the coupling element in relation to the external activation lever or is completely idle.
- no additional controls or levers are required to disable the inside control lever in any way. Rather, the associated motor vehicle door can easily be connected in the unlocked state or with the coupling element in the first coupled state be opened from the inside in the event of a crash.
- FIG. 2A shows the motor vehicle lock according to FIG. 1 in the unlocked state and in the event of a crash in a front view
- FIG. 2B shows the motor vehicle lock according to FIG. 2A in a perspective detail
- FIG. 3 shows the motor vehicle lock according to FIG. 2B in a side view from direction X
- FIG. 4 shows the motor vehicle lock according to FIG. 2 in a front view in the locked state
- Fig. 5 shows the object according to Fig. 4 again in a side view looking from direction Y.
- a motor vehicle lock which is a motor vehicle door lock.
- This has a locking mechanism 1, 2, which is only indicated in FIG.
- the basic structure also includes an inside activation lever 4, which can be seen in FIG. 2B, and an outside activation lever 5.
- a release lever 6 and a coupling element 7 are implemented.
- the coupling element 7 can be displaced in its longitudinal direction, as indicated by an arrow in FIG.
- the coupling element 7 is mounted on the release lever 6 in a linearly displaceable manner according to the exemplary embodiment.
- the coupling element 7 is acted upon by a motor in the exemplary embodiment with the aid of a locking element 10 .
- the locking element 10 is designed as an actuating cam which can be pivoted about an axis 11 .
- One end of the locking element 10 is equipped with a ring gear 10a for engaging a motor drive, not shown.
- the other end of the locking element 10 engages in the coupling element 7 with a joint 10b and ensures the described linear displacement of the coupling element 7 in relation to the release lever 6.
- the mass inertia lever 8, 9 is designed in two parts overall and has a mass element 8 and an actuating element 9 articulated therewith.
- the mass element 8 is mounted in the lock case 3 such that it can rotate about an axis 12 .
- a spring 13 is assigned to the inertia lever 8 , 9 .
- the previously mentioned spring 13 engages with a spring leg in a guide opening 15 in the mass element 8, while another spring leg is stationary in the Lock housing or lock case 3 is anchored.
- the stop 14 for the mass inertia lever 8, 9 also ensures that it can only be acted upon in a clockwise direction about the axis 12 and not in a counter-clockwise direction.
- the locking element 10 retains its position.
- the inside actuating lever 4 and also the outside actuating lever 5 can each be brought into engagement with the release lever 6 via the coupling element 7 in the engaged position and disengaged from the release lever 6 in the disengaged position.
- the coupling element 7 according to the exemplary embodiment is able to do this, depending on Expression of the operating lever 4, 5 in a shown in Figs. 2A and 3 first engaged position and in a shown in Figs. 4 and 5 second engaged position to be able to be transferred.
- the locking element 10 ensures the respective control in the first engaged position and the second engaged position of the coupling element 7.
- the first engaged position according to FIGS. 2A and 3 corresponds to the “unlocked” position of the locking element 10, whereas the second engaged position 4 and 5 to the "locked" position of the locking element 10 corresponds.
- the coupling element 7 has an outer actuating lever contour 7a and an inner actuating lever contour 7b.
- the external actuating lever contour 7a is provided on the head side of the coupling element 7.
- the inside actuating lever contour 7b is a pin 7b adjoining the inside of the outside actuating lever contour 7a.
- the design is such that the external actuating lever 5 can interact with the external actuating lever contour 7a with a projection 5a when the coupling element 7 is in its starting position shown in FIG. 1 or the first engaged position according to FIGS. 2A, 2B and is in the "unlocked” state.
- This interaction corresponds to the fact that the coupling element 7 and the release lever 6 can perform a pivoting movement, indicated in FIG.
- the inside actuating lever contour or the pin 7b In the “unlocked” state or in the first engaged position of the coupling element 7, this can interact with a chamfer 4a on the inside actuating lever 4.
- the design is then further such that in the first engaged position according to FIGS. 2A, 2B and in the event of a crash, only the external actuating lever 5 is disengaged from the release lever 6. That is, in the event of a crash in the first engaged position according to FIGS. 2A, 2B with the clutch element 7 in its right-hand end position, it ensures that the mass inertia lever 8, 9 or the mass element 8 is pivoted clockwise about its axis 12 , so that the actuating element 9 acts on the coupling element 7 and displaces it to the left in relation to the release lever 6 in the exemplary embodiment (cf. FIG. 1). As a result, as shown in the side view according to FIG.
- the projection 5a on the release lever 5 disengages from the contour 7a of the outside activation lever and consequently a deflection of the outside activation lever 5 caused by a crash cannot act on the clutch lever 7 and thus the release lever 6.
- the locking mechanism 1, 2 remains closed.
- the locking mechanism 1, 2 can be opened directly and unchanged with the aid of the inside actuating lever 4 in the first engaged position according to FIGS. Actuation with the aid of the external actuating lever 5 is then also possible because the coupling element 7 is returned to its right-hand end position or the starting position shown in FIG. On the other hand, after the crash acceleration in the exemplary embodiment according to FIGS. 4 and 5 has ceased, it is first necessary for the coupling element 7 to be moved into its unlocked position or first engaged position with the aid of the locking element 10, so that the opening of the locking mechanism can then take place 1, 2 can be carried out via the inside operating lever 4 or the outside operating lever 5.
