    LOCK FOR A MOTOR VEHICLE
    BACKGROUND OF THE INVENTION
    FIELD OF THE INVENTION [0001] The invention concerns a lock for a motor vehicle,
    DESCRIPTION OF THE INVENTION [0002] A lock for a motor vehicle comprises a locking assembly with a rotating tongue mounted in a rotatable manner to admit a locking pin, this also called a hammer. The locking assembly further comprises a locking latch to which the rotating latch can be engaged to retain the locking pin.
    [0003] The rotating tongue of a motor vehicle normally comprises a fork-shaped entry slot (also called an entry opening), which is formed by the loading arm and the rotating tongue arm and in which the locking pin (also called d® hammer) of a vehicle door or hatch, for example, a cover or trunk lid, enters when the door or hatch is closed. The locking pin or hammer then rotates the rotating tongue from an open position to the direction of the closed position, until the tongue engages the rotating tongue. This position is called the gear position. The locking pin, then, cannot leave the entry slot of the rotating tongue.
    [0004] Additionally, a lock may comprise a locking lever capable of locking the locking latch in its engaged position. The locking lever must be pivoted or rotated out of its locked position in order for the locking tab to be able to leave its engaging position to open the locking assembly.
    2/9 [0005] There are locks such as those known in US 2010 052 336 A1 in which the rotating tongue is capable of introducing an opening torque in the locking tongue, if the latter is in its engaged position. Such a lock requires a locking lever in order to be able to engage the locking assembly. Such locks can be opened with little effort.
    [0006] There are motor vehicle locks with two gear positions, that is, a preliminary gear position and a main gear position. The preliminary gear position is used to rotate the respective door or door in a rotating way when it does not reach the main gear position during the closing process. If, starting from the preliminary gear position, the rotating lug is still rotated, correspondingly, it will finally reach the main gear position.
    [0007] As a principle, a lock comprises a release lever that is actuated in order to open or disengage a locking assembly. Such a release lever is usually attached to a door handle or hatch. If the handle is actuated, the release lever is actuated or pivoted in order to disengage the locking assembly and then open the lock.
    [0008] In the event of a collision, the handle may be actuated inadvertently, which would cause the locking assembly to open. It must be ensured that such a lock does not open inadvertently in such a case.
    [0009] In order to ensure that a lock does not open inadvertently in the event of a collision, a lock with a locking assembly is provided in accordance with EP 1518983A2, which comprises at least one actuation lever to release or open the locking assembly, that is, a release lever. THE
    The lock also comprises a locking lever that locks the actuation lever during predetermined vehicle accelerations.
    [0010] In the event of a collision, there are particularly large accelerations compared to the usual opening process. If the actuation lever blocks only large accelerations in the vehicle, as in the case of a collision, an unintentional opening of the locking assembly in the event of a collision can be prevented. In the case of a normal actuation of the door handle, the actuation lever is not blocked by the lack of a great acceleration in order to allow, then, that the lock is opened.
    SUMMARY OF THE INVENTION [0011] In view of the problems described above, the invention provides, in one aspect, a lock in which an inadvertent opening is prevented in the event of a collision.
    [0012] In order to achieve this object, according to an embodiment of the invention, a lock with a locking assembly is provided, which comprises a rotating tongue and a tongue to engage the rotating tongue. In addition, the lock may comprise a locking lever capable of locking the locking tab if the locking tab is located in its engaging position. In addition, a release lever for opening or releasing the locking assembly is provided. If the release lever is actuated, the locking lever or the locking lever is then moved out of its locking position, if the bio lever is not accelerated excessively. If excessively large accelerations of the release lever occur, such as those caused by a collision, then the locking device prevents the release lever from being able to move the locking latch or the biking lever out of its position. locking or locking, respectively. The lock is,
    4/9 therefore, unable to open if the release lever is accelerated in the event of an accident, [0013] In one embodiment, the locking device comprises an inert lever and a locking lever, The inert lever and the locking lever are interconnected in such a way that the inert lever is moved together with the locking lever by the release lever only when the release lever is accelerated in the usual manner, such as when the door handle is actuated in the common way, for example, by a driver of the vehicle, Ern such a case, the joint movement of the inert lever and the biking lever occurs in such a way that the locking lever is unable to prevent the locking assembly from being opened, if the release lever is excessively accelerated , as possible in the event of a collision, then, due to the inertia of the inert lever, only the locking lever is moved, namely, to a position in which it additionally locks and, the release lever pivot in such a way that the locking assembly is prevented from being opened.
    [0014] In an embodiment of the invention, the locking device comprises a spring that interconnects the inert lever with the locking lever, such that the inert lever is moved together with the locking lever by the release lever only when the release lever it is accelerated in the usual way Technically simple, this prevents the lock from being able to open unintentionally in the event of a collision. Acceleration in a usual manner means that there are no excessively large accelerations of the release lever (as a rule due to a collision).
    [0015] In an embodiment of the invention, a spring leg is connected to the inert lever. Such a connection is provided, in particular, if the spring leg rests against an outline of the inert lever, preferably in an inclined state. The contour can be provided by δ / 9 a projection or gap of the inert lever. Another spring leg is connected to the locking lever. Such a connection is provided, in particular, when the spring leg rests, preferably inclined, against an outline of the locking lever. A projection or gap in the locking lever can provide the contour. In the case of lower accelerations, the spring acts as a rigid connection between the locking lever and the inert lever. In the case of lower accelerations, the locking lever and the inert lever are therefore moved together by an actuation of the release lever to open the mechanism assembly. Release lever actuation occurs by the actuation of a corresponding door handle or door handle.
    [0016] In the event of a great acceleration, the spring, due to the inertia of the Inert lever, is deformed in such a way that only or at least predominantly the locking lever is moved, but not or at least practically nothing the inert lever. In particular, the spring is additionally inclined in the event of a corresponding large acceleration. If the lock lever is moved independently of the inert lever, the lock lever then enters its locked position. In the locking position, the release lever is prevented from being able to be rotated further, such that the locking assembly is opened accordingly.
    [0017] In one embodiment, the locking lever comprises a shoulder which can be moved by the release lever to move the locking lever. If the release lever is actuated, the cam and therefore the lock lever are moved.
    [0018] In a preferred embodiment of the invention, the shoulder of the locking lever provides the contour mentioned above for the spring or a spring leg.
    [0019] Preferably, the mass of the inert lever is at least two, three, four or more times greater than the mass of the lever
    6/9 lock, so that the inert lever can be reliably moved only at low accelerations of the release lever, [0020] In one embodiment of the invention, a rotating safety lever mounted against a contour of the inert lever in an Inclined manner, so that the inert lever is reliably moved only at low accelerations of the release lever, [0021] In one embodiment of the invention, the lock comprises a locking profile rigid or rotatably connected to an lock the lock, the locking profile serves to lock the locking lever if the release lever is excessively accelerated, if the locking lever is locked by the locking and s profile then is located in its locking position, the lever release cannot be rotated, in such a way that the locking set is opened according to this, [0022] The safety lever mounted in a rotatable manner comprises the locking profile in order to reduce the number of parts.
    [0023] In one embodiment, the lock may comprise a locking lever that can lock the locking tab in its locking position. In this mode, a lever can engage a shoulder on the locking lever in order to remove the locking lever from its locking position.
    [0024] In one embodiment, a release lever can act as a second locking latch in order to engage the rotating latch.
    BRIEF DESCRIPTION OF THE FIGURES [0025] The Invention is described below with reference to the attached Figures, which show:
    7/9 [0026] Figure 1 is a schematic side view of a locking assembly according to an exemplary embodiment of the invention; ........................ ............................ ...................... ...... ............................................ ....................................
    [0027] Figure 2 is a first detailed view of the locking device according to the exemplary embodiment of the invention;
    [0028] Figure 3 shows a second detailed view of the locking device according to the exemplary embodiment of the invention.
    DETAILED DESCRIPTION OF THE INVENTION [0029] As shown in Figure 1, the locking assembly of a lock comprises a rotating latch 1, a locking latch 2, a locking lever 3, an inert groove 4 below the locking lever 3 and a safety lever 5. Rotating latch 1, locking latch 2, inert lever 4 and safety lever 5 are rotatably mounted on a metal plate 6. Additionally, there is a release lever. Figure 1 shows a section 7 of the release lever. The release lever 7 can be positioned above the locking tab 2 and can be rotatable on an axis 9.
    [0030] The rotary tab 1 can rotate about its axis 8. The locking tab 2 can rotate about its axis. The inert lever 4 can rotate about its axis 10. The weight of the inert lever 4 is much greater than the weight of the locking lever 3, at least two, three, four or more times.
    [0031] As shown in Figure 1, the locking tab 2 blocks a clockwise rotation of the rotating tab
    1. Therefore, the locking tab 2 is in its engaged position. In order to unlock the locking set, it is necessary to turn locking tab 2 clockwise. When locking latch 2 has reached its engaging position, rotary latch 1 can rotate clockwise in the direction of its position
    8/9 open. When the rotating latch 1 reaches its aborted position, the lock support 11 of a vehicle door or vehicle door can leave the locking assembly. It is then possible to open the corresponding door or hatch.
    [0032] The locking lever 3 is rotatably mounted on the inert lever 4 adjacent to a lever arm of the release lever 7. In addition, the locking lever 3 and the inert lever 4 are interconnected by an inclined spring 12. A first leg 13 of the spring 12 rests against a projection 14 of the inert lever 4 at an angle. The second leg 15 of the spring 12 rests against a projection 16 of the locking lever at an angle, as shown in detail in Figures 2 and 3.
    [0033] Projection 10 also acts as a rebound. The lever arm mentioned above the release lever 7 can engage the shoulder 16 in order to move the lock lever 3 to the left. The locking lever 3 can be rotated about its axis 17 or together with the inert lever 4 around the axis 10.
    [0034] Activation by a drive or by another person of a corresponding cable from a vehicle connected to the locking assembly, such as a Bowden cable or other known means, results in rotation of the release lever 2 in a clockwise direction. In such a case, the corresponding release lever arm moves the locking lever 3 to the left. When the acceleration is low, the spring 12 acts as a rigid connection between the inert lever 4 and the locking lever 3. For this reason, movement of the locking lever 3 to the left results in rotation of the inert lever 4, together with the locking lever 3 counterclockwise around axis 10. Release lever 7 engages with a shoulder, respectively a projection 18, of the locking tongue 2 in order to remove the locking tongue from its
    9/9 engaged position, Finally, it is possible to open the corresponding door or hatch.
    [0035] During collisions of the motor vehicle, parts of the door handle or other vehicle components can accelerate and cause unwanted cable action, resulting in a strong acceleration of the release lever 7, A strong acceleration of the release lever 7 results in a strong acceleration locking tab 3 to the left. In this case, the spring 12 does not act as a rigid connection between the locking lever 3 and the inert lever 4 due to the high weight and inertia resulting from the inert lever 4 and / or due to a frictional force between the inert lever 4 and the safety lever 5, since the safety lever 5 rests at an angle in an outline of the inert lever 4, As a result, the Inert lever 4 does not rotate about its axis
    10. Instead, the locking lever 3 rotates clockwise, in the direction of the position as shown in Figure 3, about its axis 17.
    [0036] When the lock lever reaches the position as shown in Figure 3, the safety lever 5 can block a movement of the lock lever 3 to the left. In such a case, an additional clockwise rotation of the release lever 7 is not possible. As a result, the locking tab 2 will rest in its engaged position, as shown in Figure 1.
    [0037] The movement of the inert lever 4 back to its starting position, as shown in Figure 1, can be achieved by gravity and / or by an additional spring, [0038] The safety lever mounted in a rotatable way can be rotated about its axis 19, Due to a spring 20, the safety lever rests against an outline of the inert lever in an Inclined manner,
