Definitions
- the invention relates to a locking device, in particular for a motor vehicle with a lock comprising a lock mechanism and a release lever for opening the lock mechanism and a trigger actuating lever for triggering the release lever.
- a lock for a motor vehicle comprises a lock mechanism, namely in principle 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 Einiaufschlitz formed by load arm and tentacle (also called inlet mouth), in which the locking bolt of a vehicle door or flap, for example, hood or trunk lid, passes when the door or flap is closed.
- 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 Drehfaile starting from the pre-locking accordingly rotated further, this finally reaches the main detent position.
- a lock has a release lever that is actuated or released by means of a release actuation lever in order to open or unlatch a locking mechanism.
- a trigger actuating lever is typically connected to a handle of a door or flap. If the handle is actuated, the trigger actuating lever is actuated or pivoted. As a result, the release lever is actuated or pivoted to detent the locking mechanism and thus to open the lock.
- a locking device with a locked lock can also be locked. If the locking device is locked, pressing a handle does not result in the lock being unlatched. An associated door or flap can not then be opened by pressing a handle.
- the handle can be actuated unscheduled, which can lead to an opening of the locking mechanism. It should be ensured that such a lock then does not open unplanned.
- EP 1 518983 A2 discloses a lock provided with a locking mechanism which comprises at least one actuating lever for triggering or opening the locking mechanism, that is to say a triggering lever.
- the lock also has a locking lever, the actuating lever at a given
- the object of the present invention is to provide a lock in which an unplanned opening is avoided in the event of a crash.
- the shooting device comprises a lock with a lock mechanism.
- the lock includes a release lever for a Opening the lock mechanism.
- the locking device has a trigger actuating lever for triggering the trigger lever.
- the release lever In an initial position, the release lever is not coupled with the release lever and the lock mechanism is locked. Further, there is a coupling member which couples the trigger operating lever with the trigger lever for opening the lock mechanism when the trigger operation lever is operated from the home position. The coupling member does not engage the tripping operation lever with the tripping lever for opening the lock when the tripping operation lever is excessively accelerated from the home position by operation. So there is a limit acceleration, the exceeding of which has the consequence that the coupling member does not couple and therefore does not result in an actuation of the trigger actuating lever, that the lock mechanism opens.
- the lock mechanism is basically provided by a locking mechanism comprising a catch and a pawl for rusting the catch.
- the lock preferably further comprises a blocking lever capable of blocking the pawl when in its latching position.
- Other lock mechanisms are also possible.
- the lock may include a pre-locking pawl, which may be basically identical or integral with the release lever.
- the pawl can be moved out of its detent position directly by the release lever.
- This embodiment usually does not include a blocking lever for blocking a pawl.
- the blocking lever is thereby moved out of its blocking position when the release operating lever is not excessively accelerated.
- the lock can not open when, for example, the trigger actuating lever and / or an associated handle of a door or flap are correspondingly accelerated in the event of a crash.
- the coupling member is moved by a spring in the coupling position.
- a spring has the property of being able to act as a rigid body with sufficiently slow movements, so as to move the coupling member into its coupling position. At excessively large accelerations, however, the spring behaves due to the inertia of the coupling member is not like a rigid body, but is stretched. The inertia of the coupling member can thus be used to prevent the coupling member from being moved to the coupling position at excessively high accelerations by the spring.
- the spring can be moved in particular by the trigger actuating lever. In this way it can be achieved in a simple manner that the coupling member is moved in the manner described in order to couple at sufficiently low accelerations and not to couple at excessively high accelerations.
- a further spring may be provided, with which the coupling member can be moved from its coupling position back to an initial position. In a technically simple manner is achieved so that the spring can be moved appropriately.
- the coupling member is preferably rotatably attached to the release lever. This attachment is particularly well suited to be able to move the coupling member as planned in its coupling position.
- one end of the coupling member may be, for example, by means of a bolt on a contour of the release lever rest when the coupling member is in the non-coupling position.
- the contour thus represents a limitation for the coupling member, which advantageously prevents excessive pivoting. This ensures trouble-free operation.
- One arm of the trigger actuating lever can detect the coupling member in the coupling position in a structurally simple embodiment. It is made in a particularly simple manner, a coupling between the trigger actuating lever and the trigger lever when the trigger actuating lever is not accelerated excessively.
- the coupling member is preferably made of metal in order to provide a sufficiently large inertial mass, without having to provide excessively large space therefor.
- a locking lever is provided which can be pivoted from a locking position to a non-locking position, and vice versa.
- the locking lever prevents in its locking position that the coupling member can get into its coupling position. It succeeds in a technically simple and very reliable way to lock a lock. This also prevents a lock from being able to open unintentionally due to rebound effects at excessively high accelerations.
- the locking lever can be pivoted in an advantageous embodiment by pivoting the release lever in its non-locking position.
- a suitable movement of the locking lever is achieved in its non-locking position and that is when a lock should be opened according to plan. Because the pivoting of the trigger then has in particular the consequence that a Lock mechanism is opened, so in particular a locking mechanism is unlocked.
- one end of the coupling member is advantageously located above the arm of the trip actuating lever, as seen from the axis of the trip actuating lever. Then the Kupplungsgiied can not be pivoted into its coupling position. This further avoids the possibility that a lock may open unscheduled due to rebound effects. It can be provided such a large Kochhub that certainly the coupling member is moved back by rebound, and then unscheduled to get into its coupling position.
- the release lever for a Bowden cable or a linkage.
- the release lever can be connected to a handle, so as to open the lock by pressing the handle can.
- the handle may be an outside handle or an inside handle of a door or flap.
- the trip lever, the triggering he and the coupling member are arranged in three different levels to provide a suitable locking device can.
- a sensor that is able to detect a crash.
- This may be, for example, a sensor that is already provided for activating airbags. If the sensor detects a crash, then advantageously the locking lever is moved into its locking position. This additionally prevents that by rebound effects the lock can be opened unplanned.
- the sensor can be designed so that it can detect excessively high accelerations, as they can occur in the event of a crash.
- the sensor can alternatively or additionally be a tilt sensor, which is able to detect inclinations, such as these can occur in the event of a crash.
- a particular advantage is that an unscheduled opening of a lock is not realized by a blocking concept. In the event of a crash, advantageously no force is introduced into the locking system which could have a destructive effect.
- FIG. 1 shows components of a locking device according to the present invention in an unlocked position of the locking device. Shown are a trigger actuating lever 1 and a release lever 2. The trigger actuating lever 1 and the release lever 2 can be pivoted about a common axis 3. The trigger actuating lever 1 is thus arranged in a different plane than the trigger lever 2. There is a coupling member 4, which is pivotally mounted at the end of an arm of the release lever 2. The coupling member 4 can be pivoted about the axis 5, which is fixed to said arm of the release lever 2. The coupling member 4 is arranged in a plane between the plane of the release lever 2 and the plane of the release lever 1. A
- Leg spring 6 is held by the axis 3. A leg 7 of the leg spring 6 abuts a projection 8 of the release lever 1. The other leg 9 of the leg spring 6 abuts against an arm 1 0 of the coupling member 4.
- spring 6 it is achieved that a pivoting of the release lever 1 in a clockwise direction has the consequence that the coupling member 4 can be pivoted counterclockwise opposite.
- spring ensures that the Kupplungsgiied 4 rests with a pin 1 1 on a contour 12 of the release lever 2 in a basic position.
- the coupling member 4 is thus spring-loaded correspondingly by a prestressed spring, which introduces a clockwise torque in the case of Figure 1 in the coupling member 4.
- this spring may be attached to the arm with the bolt 1 1 and the other end of this spring at a suitable location on the trigger actuating lever. 1 But it may also be a spring which is held by the axis 5, that extends around the axis 5 around. One end of this spring, not shown, is then suitably connected to the release lever 2 and the other end suitably connected to the coupling member. 4
- locking lever 13 which can be pivoted about an axis 14.
- the locking lever 1 3 is pivoted away from the coupling member 4. There is then no contact between the locking lever 13 and the coupling member 4.
- the locking lever is preferably arcuate in order to lock suitable as described below can.
- stage 1 9 on the side facing the coupling member.
- a stage 1 9 can take care of a particularly suitable support of the locking lever on the actuator 4 in the locked state and / or limit pivotal movement of the release lever 2 suitable when the Ausittlehebel 2 is used as described below to the locking lever 13 from his to swing out the locking position.
- an arm of the trigger actuating lever 1 there is a suspension, for example in the form of a bore 15, in which one end of a Bowden cable or a linkage can be hung or otherwise attached.
- the other end of the Bowden cable or linkage is then connected to a door handle or handle a flap. If the handle is actuated, the release lever 1 is pivoted clockwise.
- the arm with the hole 1 5 is long compared to its other arm 16. It is thus provided a favorable leverage to open the lock with little effort.
- the coupling member 4 has a coupling arm 1 7, with a scheduled coupling is possible.
- This clutch arm 1 7 can couple with the arm 1 ⁇ of the trip lever 1 when the trip lever 1 is not excessively accelerated.
- the end of the coupling arm 1 7 is angled, for example in the direction of the plane in which the trigger actuating lever 1 is located. The angled end can then be detected by the arm 1 6 for a Kuppein.
- the coupling member 4 has to be pivoted counterclockwise about its axis 5 in order to couple in a planned manner and thus open the lock mechanism to be able to. If the locking lever 1 3 is pivoted clockwise and so contacts the coupling member 4 as shown in Figure 2, the coupling member 4 can not be pivoted counterclockwise opposite. Opening the lock mechanism is then not possible by pressing a handle. In particular, this also prevents a lock from being able to open unpially due to rebound effects.
- the locking lever 13 is in particular part of a central locking in order to lock one or more flaps and / or one or more doors of a motor vehicle at the same time by at least one electric drive.
- the release lever 2 has in one embodiment, an arm with an angled end 1 8, with the locking lever 1 3 can be moved back to its unlocked position.
- the release lever 2 is pivoted by an electric drive in the U-clockwise direction.
- the angled end 18 can then detect the Verriegeiungshebel 13 and opposite to the clockwise turn about its axis 14 in its position not locking position.
- the spring 6 behaves at least as much as a rigid body, that the coupling member 4 is pivoted practically simultaneously about its axis 5 opposite to the clockwise direction.
- the coupling member 4 can then, as shown in Figure 3, the release lever 1 with the release lever 2 couple.
- the arm 1 ⁇ of the triggering lever 1 detects the coupling arm 1 7 of the coupling member 4.
- the release lever 2 is also pivoted clockwise.
- the spring 6 does not behave like a rigid body due to inertia of the coupling member 4. Since the coupling member 4 is then not pivoted together with the trigger actuating lever 1 practically at the same time, the arm 16 of the actuating lever 1 does not engage the coupling arm 17 of the coupling member 4 as shown in FIG. The arm 1 6 instead passes below the coupling arm 1 7, so that even then the coupling member 4 can not be pivoted.
- the width of the end of the arm 1 6 or the corresponding length of the contour determines the length of a lifting movement, which can cover the Kuppfungsglied 4 seen from the coupling position.
- the coupling member 4 is wholly or at least predominantly made of metal.
- the other levers such as Ausittlebetuschistshebel 1 and / or tripping lever 2 and / or the locking lever 13 are in the Rule wholly or predominantly of metal, to ensure adequate stability.
- triggering lever 1 and / or release lever 2 wholly or partly made of plastic.
