Definitions

  • the invention relates to a lock for a motor vehicle according to the preamble of claim 1.
  • a lock for a motor vehicle includes a locking mechanism with a rotatably mounted rotary latch for receiving a locking bolt, which is also called lock holder.
  • the locking mechanism further has a pawl with which the catch can be latched for holding the locking bolt.
  • the catch of a motor vehicle lock usually has a bifurcated inlet slot formed by load arm and catching arm (also called infeed mouth) into which the locking bolt of a vehicle door or flap, for example bonnet or boot lid, arrives when the door or flap is closed.
  • load arm and catching arm also called infeed mouth
  • the locking pin or lock holder then rotates the catch from an open position towards the closed position until the pawl locks the catch. This position is called detent position.
  • the locking bolt can then not leave the inlet slot of the rotary latch.
  • a lock may also include a blocking lever capable of blocking the pawl in its detent position.
  • the blockage lever must be pivoted out of its blocking position or turned out so that the pawl can leave its locking position for opening the locking mechanism.
  • the pre-detent position serves to intercept the corresponding door or flap if it does not reach the main detent position when closing. If the rotary latch is rotated further starting from the pre-latching position, this finally reaches the main latching position.
  • a lock basically has a release lever that is operated to open or unlatch a ratchet.
  • a trigger lever is typically connected to a handle of a door or flap. If the handle is pressed, the release lever is actuated or pivoted to detent the locking mechanism and thus to open the lock.
  • the handle can be operated unscheduled, which would lead to an opening of the locking mechanism. It should be ensured that such a lock then does not open unplanned.
  • a lock provided with a locking mechanism, which comprises at least one actuating lever for triggering or opening the locking mechanism, that is, a release lever.
  • the lock further includes a locking lever which blocks the operating lever at predetermined vehicle accelerations.
  • the publication DE102011010816A1 discloses a motor vehicle door lock, which is equipped with a locking mechanism 1, 2, 3, further with a working on the locking mechanism 1, 2, 3 operating lever mechanism with a release lever 4, and with a locking lever 10.
  • the locking lever 10 blocks the locking mechanism 1, 2, 3 at least when occurring acceleration forces of predetermined size, for example in an accident (crash case).
  • the invention has for its object to improve a lock and further, in particular such that in the event of a crash unplanned opening is avoided.
  • a lock in particular for a door or flap of a motor vehicle, with a locking mechanism comprising a catch, a pawl for locking the catch in a locking position, preferably a blocking lever for blocking the pawl in its latching position and a release lever for opening the locking mechanism in particular provided by a lifting of the blocking lever from its blocking position.
  • the lock comprises a locking device which comprises a blocking position, such that the locking device is able to prevent the locking of the locking mechanism in the event of excessive acceleration, in particular of the release lever and / or an associated handle of a door or flap.
  • the lock further comprises an anti-rotation device, which is able to prevent a shock-related or pulse-related opening operation of the locking mechanism.
  • Essential is the consideration to provide an anti-rotation, by which a shock-related or pulse-induced opening operation of the locking mechanism can be prevented, preferably by appropriate intervention can be blocked.
  • a blocking finger or locking stop the blocking lever and a locking finger or locking stop are assigned to the release lever, the rotation is such that the rotation only locks a movement of the blocking lever, if the locking device at excessive acceleration or crash acceleration, the opening of the locking mechanism prevented.
  • the invention prevents in this position, the rotation of the lifting of the blocking lever from its blocking position by pushing the locking finger or locking stop of the blocking lever against the locking finger or locking stop of the release lever, such a blockade does not take place when the trigger lever is in a different position.
  • the rotation is then such that the occurring in particular in the event of a crash excessive acceleration, which can affect especially as pulses or shocks on the locking mechanism, do not cause the locking mechanism, for example, even without contact of the release lever automatically due to inertia solves. This makes it possible to prevent a crash-induced or shock-related opening of the locking mechanism.
  • the anti-rotation comprises a plurality of locking fingers and / or locking stops.
  • a locking finger or locking catch are assigned to the blocking lever and a locking finger or locking stop to the triggering lever in the rotation.
  • the locking fingers and / or locking stops as pins, bolts, pins o. The like. Be configured. As a result, the rotation can be provided in a space-optimized manner at the castle.
  • the anti-rotation is such that a blocking of the opening process of the ratchet takes place exclusively in a shock-related or pulse-induced movement process of the blocking lever.
  • the rotation in a regular opening and / or closing operation of the locking mechanism, in particular in a corresponding rotation of the release lever expediently cause no blocking.
  • the functionality of the lock is ensured in regular use. The lifting of the blocking lever to open the locking mechanism and the collapse of the blocking lever to block the locking lever are still guaranteed in this way.
  • the rotation is designed for blocking the rotational movement of the blocking lever, preferably in such a way that locking fingers and / or locking stops can be brought into engagement in the opening direction from a predetermined rotation of the blocking lever.
  • the arrangement of the rotation is then made such that the one or more locking fingers and / or locking stops engage only from a predetermined rotation of the blocking lever.
  • the blocking lever can therefore be locked from a certain rotation or a Leerhub to prevent unwanted opening operation of the locking mechanism.
  • a shock-related or impulse-related movement process of the blocking lever can be reliably locked, the idle stroke improves the functionality for a regular opening and closing of the locking ensures.
  • the rotation for example in the form of locking fingers and / or locking stops can be directly or indirectly attached to the blocking lever and / or release lever.
  • the locking fingers and / or locking stops can be designed in one piece with the blocking lever and / or release lever.
  • the blocking lever locking finger and / or locking stop is arranged adjacent to the blocking contour section.
  • the locking finger and / or locking stop is then located on the arm of the blocking lever which is associated with the blocking contour section.
  • the arrangement is such that, viewed in the opening direction of the blocking lever, the locking finger and / or blocking stop is arranged in front of the arm of the blocking lever.
  • a lock is provided with a locking mechanism comprising a catch and a pawl for locking the catch.
  • the lock further includes a blocking lever which is capable of blocking the pawl when it does is in its rest position.
  • a release lever for opening or releasing the locking mechanism.
  • the blocking lever is thereby moved out of its blocking position if the release lever is not accelerated excessively. If excessively high accelerations of the release lever occur, as can be caused by a crash, then a locking device of the lock prevents the release lever from being able to move the blocking lever out of its blocking position. Therefore, the lock can not open if the release lever in the event of a crash is accelerated accordingly strong.
  • the locking device comprises at least two locking positions. Is the locking device in a first blocking position, for example as a result of an excessively accelerated release lever, in particular caused by an impact in a crash, and releases the locking device from the first locking position, for example due to a rebound, in particular delayed and / or repeated rebound
  • the locking device can continue to avoid by taking a second or further blocking position that the locking mechanism opens, so in one embodiment, the release lever moves the blocking lever out of its blocking position.
  • the locking device in one embodiment comprises an inertia lever and a locking lever.
  • Inertial lever and locking lever are connected together so that the inertia lever is moved together with the locking lever by the release lever only when the release lever is accelerated in the usual manner, as in a usual operation of the door handle is the case.
  • the joint movement of the inertia lever and locking lever takes place in such a way that the locking lever can not prevent the opening of the locking mechanism.
  • the handle and associated trip lever are generally not excessively accelerated.
  • the inertia lever and locking lever are connected to each other so that when strongly accelerated release lever or greatly accelerated grip a door or flap, as in a crash is possible due to the inertia of the inertia lever only the locking lever is moved in one of the blocking positions of the locking device, which blocks further pivoting of the release lever or the handle such that an opening of the locking mechanism is avoided.
  • the locking means comprises a spring which interconnects the inertia lever and the lock lever so that the inertia lever is moved together with the lock lever by the release lever only when the release lever is accelerated in a conventional manner.
  • One leg of the spring is connected in one embodiment of the invention with the inertia lever. Such a connection is in particular present when the leg of the spring is preferably biased against a contour of the inertia lever. Another leg of the spring is connected to the locking lever. Such a connection is present in particular when the leg of the spring preferably biased against a contour of the locking lever.
  • the spring acts as a rigid connection between the locking lever and the inertia lever. At low accelerations therefore locking lever and inertia lever are moved together by pressing the release lever for opening the locking mechanism.
  • the spring is deformed so that only the locking lever is moved, but not the inertia lever.
  • the spring is further biased at a correspondingly strong acceleration. If the locking lever is moved independently of the inertia lever, then the locking lever then enters its position locks. In the blocking position it is prevented that the release lever can be further rotated in such a way that this causes an opening of the locking mechanism.
  • the locking lever comprises a driver that can be moved by the release lever for moving the locking lever. If the release lever is actuated, the driver and thus the locking lever are moved.
  • the catch of the locking lever passes through a slot of the inertia lever, so as to allow a relative movement between the locking lever and the inertia lever.
  • the mass of the inertia lever is several times greater than the mass of the locking lever so as to achieve reliable, that the inertia lever is moved only at low accelerations of the release lever.
  • the mass of the inertia lever is two times, preferably three times, more preferably four times greater than the mass of the locking lever.
  • the lock has a locking contour, which is rigidly connected to a lock case of the castle.
  • the locking contour is used to lock the locking lever when the release lever is accelerated excessively. If the locking lever is locked by the locking contour and thus is in its blocking position, the release lever can not be further rotated so that thereby the locking mechanism is opened.
  • the locking contour is arranged flat against the inner wall of the lock case to transmit the impact forces in the attack of the locking lever to the locking contour on the lock case.
  • the blocking contour can be dimensioned so small.
  • the locking lever is connected to the inertia lever so that a projection of the locking lever adjacent to the outer contour of the inertia lever at not excessive acceleration of the trigger lever or handle, to that portion of the outer contour of the inertia lever, which when pivoting for opening a still locked in locking position locking the locking contour faces and / or maximum distance from the axis of the inertia lever has. Due to the small distance between locking lever and locking contour with locked locking mechanism, a particularly rapid locking of the locking mechanism by the locking device in the event of a crash and rebound can be effected.
  • the locking contour has an arc whose center corresponds to the axis of the inertia lever.
  • the radius of the arc is greater by a gap width than the maximum distance of the outer contour of the inertia lever from the axis thereof. Due to the small distance between the locking lever and Lock contour with locked locking mechanism, a particularly rapid locking of the locking mechanism by the locking device in the event of a crash and rebound can be effected.
  • the locking lever at the one end has a projection which faces radially outward with respect to the axis of the inertia lever. If the locking lever is moved relative to the inertia lever due to excessive acceleration of the release lever and / or handle, so the projection in the direction of the locking contour or is facing the locking contour and ensures that the locking lever is held securely in a locking position in the locking contour , This helps to provide a plurality of blocking positions in a technically simple manner.
  • the locking contour comprises a stop and / or at least one recess for locking the locking lever when the trigger lever and / or handle is excessively accelerated.
  • the recess or the recesses are preferably arranged counter to the clockwise starting from the stop in the circumferential direction of the inertia lever.
  • a blocking position of the locking device or the locking lever can be determined by the stop or the recess or recesses.
  • Setting a blocking position by, for example, a stop or a recess means that a blocking position is then occupied by the locking device when the stop or the recess by blocking or blocking the locking lever are able to prevent unscheduled opening of the lock.
  • a recess which is preferably arranged in the circumferential direction of the inertia lever counterclockwise, allows a renewed engagement or locking of the locking lever and thus avoiding unscheduled opening of the locking mechanism in the case of rebound effects.
  • a recess of the locking contour is formed triangular. Due to the triangular configuration of a recesses a self-centering when locking the projection of the locking lever is effected in the recess and allows a particularly high reliability of the locking device.
  • the locking lever has a triangular-shaped projection with bevels on both sides, wherein the counter-clockwise slope has a smaller pitch than the other opposite slope of the projection, which is arranged in a clockwise direction about the axis of the locking lever. Due to the different slopes of the slopes of the projection, a particularly secure hold of the locking device or the projection of the locking lever in the blocking positions can be effected in the event of a crash.
  • a recess of the locking contour is adapted to the projection of the locking lever in the locking position, which is defined by the recess.
  • this adjustment takes place in the overlapping area.
  • such an adjustment includes the slopes of the slopes of the Tab of the locking lever with a.
  • the stop comprises a bevel of the blocking contour, which is substantially parallel to the slope of the projection of the locking lever in the locking position, which can come in case of locking of the locking mechanism by the locking means in contact with the stop. Due to the substantially parallel shaped bevels can be made smaller by the flat power receiving the stop and the projection.
  • the axis of the locking lever is disposed on the projection opposite end of the locking lever. Due to the arrangement of the axis in preferably the greatest possible distance from the projection, a particularly large pivoting of the projection of the locking lever when actuated by the lever arm of the release lever can be realized and thanks to the thus obtained overlap of the projection in the locking contour a particularly secure hold of the locking device are effected in the blocking position ,
  • the rotation is such that the rotation only locks a movement of the blocking lever when the locking device prevents the opening of the locking mechanism with excessive acceleration or crash acceleration. This ensures in an improved manner that the shocks or pulses occurring in particular in the event of a crash do not cause the locking mechanism to open.
  • Anti-twist device and locking device are preferably functionally connected via the common release lever.
  • the release lever may accordingly have a locking finger and / or locking stop for the rotation and be coupled to the locking lever and / or inertia lever of the locking device. In that regard, a particularly safe and reliable lock is provided by the coupling of the rotation with the locking device.
  • the rotation is designed so that the blocking lever is in the locked by the rotation locked position with a sufficiently large blocking contour portion of the pawl, preferably such that the blocking contour section at least a quarter, more preferably at least half, with the pawl can be brought into engagement.
  • This results in a correspondingly large stop between the blocking contour section of the blocking lever and the pawl.
  • the locking finger and / or locking stopper is configured as an outstanding pin, pin, pin or the like on the blocking lever and / or triggering lever.
  • the locking finger and / or locking stop extends substantially parallel to the axis of rotation of the blocking lever and / or release lever. This allows a compact and reliable with the pivoting about a rotational axis effected rotation.
  • the proposed lock is applicable in all conceivable closing devices. In a particularly preferred embodiment, however, the proposed lock is used in motor vehicles.
  • the FIG. 1 shows a particular metal lock case 1 of a castle that serves to support a Gesperres.
  • the ratchet comprises a rotatably mounted, preferably predominantly made of metal rotary latch 2, which can be rotated about its axis 3 around.
  • the locking mechanism also comprises a main latching pawl 4, preferably made predominantly of metal, and a pre-ratchet pawl 5, which is preferably made predominantly of metal.
  • the main catch pawl 4 and the Vorrastsperrklinke 5 are arranged one above the other and have a common axis of rotation 6, by which the two pawls 4 and 5 can be rotated independently.
  • the ratchet further comprises a blocking lever 7, as in the FIG. 1 shown the main latch pawl 4 in the illustrated locked position of the Blocking locks is possible.
  • the catch 2, the main catch pawl 4 and the blocking lever 7 are located substantially in a common plane. In an overlying level is the Vorrastsperrklinke. 5
  • the rotary latch 2 In order to lock the catch 2 in the pre-locking position, the rotary latch 2 has a protruding pin 8 which can be moved against the lever arm 9 of the Vorrastsperrklinke 5 for locking in the pre-locking position. The end of the lever arm 9 then prevents clockwise rotation of the rotary latch 2 in the direction of its open position.
  • the rotary latch 2 is able to initiate an opening moment in the main latching pawl 4. If the blocking lever 7 leaves its blocking position, then the main latching pawl 4 moves out of its rest position due to the opening moment introduced. The catch 2 can then be moved to its open position by rotating about its axis 3 in a clockwise direction.
  • the Vorrastsperrklinke 5 also represents the release lever of the lock. If the release lever 5 is rotated clockwise and so actuated, so detects a projection 10 of the Vorrastsperrklinke 5 a driver 11 of the blocking lever 7 and thus rotates the blocking lever 7 from its blocking position when the Vorrastsperrklinke 5 or the trigger lever 5 is not excessively accelerated.
  • the end of a lever arm 12 of the release lever moves a driver 13 in the FIG. 1 concealed locking lever of a locking device.
  • the locking lever is rotatably connected by an axis 14 with an inertia lever 15. Under the inertia lever 15, the locking lever is arranged.
  • the driver 13 passes through Slot 16 of the inertia lever 15 and is detected above the inertia lever 15 from the lever arm 12 of the Auslesehebels 5.
  • the locking lever is pivoted about its axis 14 in the clockwise direction, but not the inertia lever 15 about its axis 17. This is among other reasons, because the driver 13 of the locking lever extends through the slot 16, which allows a relative movement between the locking lever and the inertia lever 15.
  • One end of the locking lever arrives at excessive acceleration so in a locking position, which is effected by a rigidly attached to the lock case 1 locking contour 18. This prevents that the release lever 5 can be further rotated clockwise for a move out of the blocking lever 7 from its blocking position. It is thus avoided that the blocking lever 7 is moved out of its blocking position for opening the locking mechanism, namely by turning the blocking lever 7 about its axis 19.
  • the blocking contour 18 comprises a stop 25 and the recesses 26 and 27, by which the blocking positions (25, 26, 27) of the locking device or the locking lever 21 are fixed.
  • the locking lever 21 has a triangular projection 28 with bevels on both sides, wherein the counterclockwise inclined 29 has a smaller pitch than the other, opposite slope of the projection, which is arranged in a clockwise direction about the axis 14.
  • the stop 25 is formed as a slope of the locking contour 18, which is substantially parallel to the slope 29 of the Projection 28 of the locking lever 21 is in the locking position. When locking the locking mechanism by the locking device, the slope 29 can come into contact with the stop 25.

  • the inertia lever 15 includes at the lower end a gap 20 which serves to connect to a leg of a spring. The leg of the spring then reaches into this gap 20.
  • the Figures 2 and 3 clarify the structure and function of the locking device in the case of a conventional opening of the lock.
  • FIG. 2 shows the initial situation when the locking mechanism is locked.
  • the locking lever 21 Below the inertia lever 15 is the locking lever 21.
  • a leg 22 of the prestressed spring 23 is located in the recess 20 and is thus connected to the inertia lever 15.
  • the spring 23 is also under the inertia lever 15 and is guided around the axis 17 around.
  • the axis 17 thus contributes to the holding of the spring 23.
  • the other leg 24 of the spring 23 is connected to the locking lever 21.
  • the leg 24 is biased on a lateral contour, for example on a downwardly extending projection of the pawl 21.
  • the spring 23 acts as a rigid connection between the locking lever 21 and the inertia lever 15. Turning the release lever 5 in the clockwise direction then causes in that the driver 13 of the blocking lever 21 is moved to the left. This turns the Actuating lever 15 together with the locking lever 21 about its axis 17 counterclockwise. The locking lever 21 then does not reach its locking position. By turning the release lever 5 clockwise, the blocking lever 7 can be moved out of its blocking position. Then the locking mechanism opens.
  • FIG. 4 shows the case when the release lever 5, starting from in the FIG. 2 situation has been excessively accelerated. Due to the comparatively large mass of the inertia lever 15, the inertia lever 15 is no longer rotated counterclockwise about its axis 17. Instead, the leg 24 is deflected and so brought into the position 24 '. The locking lever 21 is now rotated about its axis 14 in a clockwise direction and moved into its blocking position, which in the FIG. 4 is shown.
  • the blocking position 25 is reached when the end 28 of the locking lever 21 covers the stop 25, so that the inertia lever 15 can not be rotated counterclockwise.
  • the blocking position 25 is thus also taken when the end 28 of the locking lever 21, although the stopper 25 covers, but this does not affect, as in FIG. 4 displayed.
  • the locking contour 18 prevents now that the release lever 5 can be rotated so far about its axis 6 in the clockwise direction that thereby the blocking lever 7 is moved out of its blocking position.
