Definitions

  • the invention relates to a motor vehicle lock according to the preamble of claim 1.
  • motor vehicle lock is to be understood comprehensively in the present case. This may be the lock of a side door, a trunk lid or other closure element in a motor vehicle.
  • the motor vehicle lock in question is equipped with the usual closing elements latch and pawl, the latch in a main latching position, in a pre-latching position and in an open position can be brought.
  • the pawl is in a sunken position in which it holds the latch in the detent positions, and in an excavated position in which it releases the latch, adjustable.
  • the pawl can be in a motor and / or manual operation, which serves to open the vehicle door, lift out. For this purpose, an actuating mechanism is provided.
  • a known motor vehicle lock with the above structure shows the DE 195 05 779 A1 , It is designed as an electric lock, so that the actuation process can be done by motor.
  • the actuating mechanism on an opening drive which consists essentially of a drive motor and a drive motor downstream of the actuator.
  • the actuating element can be brought to the motorized lifting of the pawl with this in drive engineering engagement.
  • the problem with the motor vehicle lock in question is basically the crash safety.
  • high crash accelerations which, due to inertia forces, can lead to an undesired, automatic lifting of the pawl.
  • the result is an unexpected opening of the vehicle door in the event of a crash, which represents a great danger to the occupants of the motor vehicle.
  • Another known motor vehicle lock shows a constructive measure to block the unwanted automatic adjustment of the handle lever of a door handle in the event of a crash.
  • an adjustable blocking lever is provided, which is designed as a pivotable inertia element. When high crash accelerations occur with the corresponding preferred direction, the blocking lever comes into blocking engagement with another lever, which in turn is connected to the handle lever of the door handle. The adjustment of the handle lever is thus blocked in the event of a crash.
  • a disadvantage of the arrangement with inertia element is first the fact that the position of the pivot axis of the inertia element is fixed from the outset. This leads to undesirable design restrictions. Furthermore, it is disadvantageous that in the event of a crash always a certain reaction time must be calculated, namely the time required for the blocking lever to collapse. It is therefore to provide a freewheel of the handle lever, which can be a hindrance in normal operation. As a result, the above, designed for the handle lever of a door handle blocking principle with inertia element is only partially practicable.
  • the known motor vehicle lock ( DE 101 64 829 B4 ), from which the present invention proceeds, is designed as an electric lock, which has a very special construction to avoid the unwanted lifting of the pawl in the event of a crash.
  • a blocking lever is provided, which is coupled to the opening drive.
  • the blocking lever can be brought by a suitable control of the opening drive in a blocking position in which the blocking lever blocks the lifting of the pawl.
  • the opening drive is self-locking, so that the blocking position is held securely.
  • a disadvantage of the known motor vehicle lock is the fact that a manual operation is not possible or only with a large design effort. This is due to the fact that the blocking lever coupled to the opening drive must of course also be brought into the release position for the manual actuating operation. For this purpose, if necessary, provide a suitable coupling.
  • the invention is based on the problem, the known motor vehicle lock in such a way and further develop that a high crash safety is achieved with simpler design means.
  • an adjustable locking lever is provided, which is always in the blocking position and thereby blocks the lifting of the pawl. Only in the context of an actuating operation, the actuating mechanism adjusts the locking lever in the release position, so that the lifting of the pawl is possible. In the event of a crash, the blocking lever is thus already in the blocking position and does not have to be adjusted first.
  • the actuating mechanism is assigned to a Schuitenußachse pivotable, mounted in a bearing lock nut, which is preferably associated with a lock cylinder and adjustable by this for a manual operation.
  • the lock cylinder is the locking nut preferably via a suitably designed paddle or the like. coupled.
  • the Sch locatednuß is associated with an actuating lever which comes in a manual operation in engagement with the pawl or coupled to the pawl lever and lifts the pawl.
  • the blocking lever coupled to the lock nut preferably rigidly connected to the lock nut, and thereby releases the pawl in a manual operation before lifting the pawl.
  • a further opening drive for a motorized actuating operation is provided in a variant, by which the adjustment of the blocking lever is controllable.
  • the combination of the closing nut for the manual actuating operation with the opening drive for the motor-driven actuating operation is presently to be emphasized as particularly advantageous.
  • the motor vehicle lock is equipped with the usual closing elements latch 1 and pawl 2.
  • the latch 1 is engageable in a main latching position and in an open position. Possibly. can also be provided a Vorrastwolf. However, this is not important for the proposed solution.
  • the pawl 2 can be in a sunken position (Fig. 1, 3) bring, in which it holds the latch 1 in the main latching position.
  • a raised position (Fig. 6) is provided, in which it releases the latch 1.
  • the present motor vehicle lock is equipped as an electric lock with mechanical redundancy.
  • it has an actuating mechanism 3, by means of which the pawl 2 in an actuating operation both manually and by motor can be lifted.
  • an adjustable blocking lever 4 is provided, which can be brought into a blocking position (FIGS. 1, 2) and into at least one release position (FIGS. 3, 4, 5, 6, 7, 8). It can be seen from the illustration in FIG. 1 that the blocking lever 4 located in the blocking position blocks a lifting of the pawl 2, in FIG. 1 a pivoting of the pawl 2 to the left. The illustration in Fig. 3, however, it can be seen that the locking lever 4 located in the release position releases a lifting of the pawl 2.
  • the blocking lever 4 can be adjusted in this case in two different release positions, such as a synopsis of Figs. 3 and 7 results. This will be explained in more detail below.
  • the actuating mechanism 3 cooperates in a manner yet to be explained with the blocking lever 4 in such a way that it moves the blocking lever 4 into the release position during an actuating operation.
  • the blocking lever 4 remains in the blocking position.
  • the blocking lever 4 is therefore always in the blocking position and is only adjusted to the release position, if this is absolutely necessary in the context of an actuating operation. Accordingly, the blocking lever 4 is in the event of a crash already in the blocking position and does not need to be transferred to the blocking position.
  • the blocking lever 4 and all movement-coupled with the blocking lever 4 components are designed so that the occurring at high crash accelerations acting on the blocking lever 4 inertia forces are low and not to an adjustment of the Lead the blocking lever 4 out of the blocking position.
  • the locking lever 4 is to be provided with stiffening ribs or other constructive measures to still achieve the necessary strength.
  • the blocking lever 4 does not need to come directly with the pawl 2 into engagement. However, this is provided in the illustrated preferred embodiment so far.
  • the blocking lever 4 is provided with a stop surface 5, which is engageable with the pawl 2 or a lever coupled to the pawl 2 in engagement.
  • the pawl 2 or just coupled to the pawl 2 lever a counter-stop surface 6.
  • the stop surface 5 lies in the path of movement of the counter-stop surface 6.
  • This freewheel corresponds to the gap 7 shown in Fig. 1 between the stop surface 5 and counter stop surface 6.
  • the freewheel is advantageous in that jamming in particular between the locking lever 4 and the pawl 2 is avoided under all circumstances.
  • the actuating mechanism 3 has the closing nut axis 10 pivotally lock nut 11, which is preferably associated with a lock cylinder, not shown, and adjustable by this for a manual operation. In this case, a key-operated opening of the vehicle door is possible.
  • the use of a closing nut 11 is advantageous here in particular with regard to its resistance to an undesired adjustment due to high crash accelerations. By the storage of such a closing nut 11, this can also absorb high blocking forces.
  • the Sch askednuß 11 is associated with an actuating lever 12 which comes in a manual operation in engagement with the pawl 2 or a lever coupled to the pawl 2 and the pawl 2 lifts.
  • actuating lever 12 which comes in a manual operation in engagement with the pawl 2 or a lever coupled to the pawl 2 and the pawl 2 lifts.
  • a direct coupling between the operating lever 12 and the pawl 2 is provided.
  • the pawl 2 has a corresponding actuating surface 13a. The exact functionality will be explained below.
  • the blocking lever 4 is coupled to the closing nut 11 and can be adjusted by this.
  • the blocking lever 4 is rigidly connected to the closing nut 11.
  • a manual actuation process is triggered by starting from the situation shown in Fig. 1, the Sch thoroughlynuß 11, for example, by actuating the associated lock cylinder, in Fig. 1 is adjusted to the right.
  • the actuating lever 12, which is the blocking lever 4 at the same time, is thereby brought into abutment with the actuating surface 13a of the pawl 2 according to FIG.
  • the actuating surface 13a of the pawl 2 At the same time leaves the abutment surface 5, the trajectory of the counter-stop surface 6.
  • the pawl 2 is converted accordingly to its lowered position. This is done by the usual bias of the pawl 2 in the incident position.
  • the blocking lever 4 and with it the actuating lever 12 then falls back into the blocking position shown in Fig. 1. This is because in the illustrated and so far preferred embodiment of the blocking lever 4 is biased by a spring element, not shown, in the blocking position.
  • the blocking lever 4 is not assigned to a single release position. From the blocking position (FIG. 1), the blocking lever 4 can be adjusted to the left in the first release position on the one hand (FIGS. 3, 4, 5, 6) and on the other hand to the right in the second release position (FIG. Fig. 8).
  • release position so no discrete position of the locking lever 4 is meant, but only the fact that the blocking lever 4 is outside the blocking position.
  • the blocking lever 4 from the blocking position in both adjustment directions, each against the bias is adjustable.
  • the bias always returns the blocking lever 4 in the blocking position.
  • a motorized actuating operation is provided in the illustrated embodiment. It is just an electric lock with mechanical redundancy.
  • the actuating mechanism 3 has an opening drive 15 for the motorized lifting of the pawl 2. It is provided that the opening drive 15 during the motor opening operation, first the blocking lever 4 in a release position, in Fig. 1 links around, adjusted, and then the pawl 2 lifts. This will be explained in more detail below.
  • the opening drive 1 is equipped with a drive motor 16 indicated in FIG. 1 and an actuating element 17 connected downstream of the drive motor 16.
  • the adjusting element 17 preferably has a control contour 18 which is in engagement with a control lever 19 coupled to the blocking lever 4 or the like. stands or can be brought.
  • the control lever 19 can basically also be the blocking lever 4 at the same time. It is only important that the control contour 18 transfers the blocking lever 4 during the motor-driven actuating operation before the pawl 2 is lifted into the release position.
  • the adjusting element 17 is equipped with an actuating contour 20, which comes with further adjustment of the adjusting element 17 into engagement with the pawl 2 or a lever coupled to the pawl 2 and the pawl 2 lifts.
  • the pawl 2 has a further actuating surface 13b. This can be seen from a synopsis of FIGS. 5 and 6.
  • the actuator 17 is configured in a preferred embodiment substantially disc-shaped and rotatable about an actuator axis 21.
  • the control surfaces of the two contours - control contour 18 and actuating contour 20 - at least partially directed substantially radially outward.
  • the two contours 18, 20 are arranged in axially different planes on the adjusting element 17. With a suitable design of the components involved, this leads to a particularly compact arrangement, as is apparent from the drawing.
  • the Sch conductednußachse 10 and the actuator axis 21 are preferably spaced from each other and aligned substantially parallel to each other. In terms of the above compactness, it is advantageous here that the blocking lever 4 and the control lever 19 are arranged in axially different planes on the closing nut 11.
  • the closing nut 11 is designed together with the blocking lever 4, the actuating lever 12 and the control lever 19 as einstükkiges component.
  • the blocking lever 4, the actuating lever 12 and the control lever 19 are designed as separate levers, as far as the levers 4, 12, 19 is not one and the same lever. This is in the illustrated embodiment, yes in the blocking lever 4 and the actuating lever 12 of the case.
  • the individual levers 4, 12, 19 are then in turn coupled to the closing nut 11, preferably rigidly connected to the closing nut 11.
  • the proposed solution can basically be applied to all types of motor vehicle locks with or without opening drive. Accordingly, it can also be provided that, in addition to or as an alternative to an opening drive, a drive, for example a central locking drive, is provided by which the blocking lever 4 can be adjusted to the release position.
  • a drive for example a central locking drive
  • the proposed solution is applicable to a motor vehicle lock, which is associated with a tailgate or a trunk lid of a motor vehicle, as far as a mechanical coupling to an outside door handle is not provided.
  • the handle lever of such an outside door handle again represents a source of danger in the event of a crash.
