Locking device for a motor vehicle with locking in the event of a crash

description

The invention relates to a locking device comprising a locking device for a motor vehicle door or motor vehicle door, an actuating device for opening the locking mechanism, a locking device for locking the locking device and a safety device, the unintentional opening of the locking mechanism in the case of high accelerations and / or Case of high speeds can prevent.

In an accident, also called crash, in which, for example, two vehicles collide with each other, usually very high acceleration forces occur, which can amount to a multiple of the acceleration due to gravity. As a result, the locking device including the lever mechanisms such as the handle of a door or flap exposed to considerable forces, which can lead to an unwanted opening of the locking mechanism and consequently an unwanted opening of the associated door or flap.

Attention is drawn to the publications EP 1 518 983 A2, WO 2012/013182 A2, DE 10 2014 014 619 A1, DE 100 34 670 A1, DE 42 29 068 A1 and DE 25 08 834 A1 and German Patent Application No. 102016209608.7.

The aforementioned features known from the prior art can be combined individually or in any combination with one of the objects and embodiments according to the invention described below.

It is an object of the invention to provide a further developed locking device.

To solve the problem, a locking device according to the main claim is used. Advantageous embodiments will be apparent from the dependent claims. To achieve the object, a locking device comprising a locking mechanism for closing a motor vehicle door or motor vehicle door, an actuating device for opening the locking mechanism, a locking device for locking the locking device, a safety device, the unintentional opening of the locking mechanism in the case of high accelerations and / or in the case of high speeds, and a controller for activating the locking device for locking the locking device in the case of high accelerations and / or high speeds. A folding device is provided, which is arranged to ensure that the closing device is locked by the locking device when the locking device has been activated by the controller.

When using such a control, it may happen that accelerations and / or speeds occur in which the controller only very briefly activates the locking device, so that the locking device can not complete the locking process and goes into an undefined intermediate state, in which a unintentional opening of the vehicle door or vehicle door can not be reliably prevented. By providing the flanging device is ensured in such a case that the locking operation is performed in the intended manner to the end, so that in particular in the event of a crash inadvertent opening of the vehicle door or vehicle door can be reliably prevented.

Concretely, this may be described in more detail by an example of a controller arranged to contact or release an electrical contact or a movable switch electrical switch by high acceleration and / or high speed. Contact can be eg pressing. Loosening can be released, for example, from a depressed state. In a first embodiment, the closing device may be arranged so that only as long as the electrical contact or switch remains contacted, the locking device is activated. In a second embodiment, the locking device may be arranged so that only as long as the electrical contact or switch remains dissolved, the locking device is activated. Thus, in the first or second embodiments, if the contacting or disengagement stops before the locking operation has been completed, it may happen that the locking device transitions to the above-mentioned undefined intermediate state.

For example, in such an undefined intermediate state, a bolt driven by the locking motor may have already been moved into contact with the intended mating contour for locking, but without reaching the planned locking position, so that the bolt is not yet reliably locked to the mating contour. Unintentional opening of the vehicle door or vehicle door can not be reliably prevented. The flanging device can then ensure, for example, that the electrical contact or switch is contacted at least as long as in the first embodiment and / or remains dissolved in the second embodiment until the locking process is over. The bolt has then reached the intended locking position, so that in particular in the event of a crash inadvertent opening of the vehicle door or vehicle door can be reliably prevented.

In one embodiment, the controller includes a switch that may be actuated by contacting or releasing a component of the actuator and / or the safety device to activate the latch. The component is a mechanical component, in particular a lever-like component. Additional components for actuation can thus be saved and a closing device with particularly few parts can thus be provided.

In one embodiment, the component can engage in a detent position and / or be held in the detent position. A locking of the locking device by pressing the switch can be ensured very reliable. In one embodiment, the component can actuate the switch only when reaching the detent position or after reaching the detent position and / or hold the switch in an actuated state in the detent position. A particularly reliable operation of the switch can be guaranteed.

In one embodiment, the closing device is set up so that, by unlocking the closing device, the component can leave the locking position and / or can be moved back into a starting position. A complex backward movement of the components by the user or by a workshop can be omitted. In the unactuated state of the actuator and / or the standby state of the safety device, the component is in the starting position. If the component is the outside operating lever, the home position will be the home position.

In one embodiment, the component is an inertia member, a mechanical safety member, and / or an external actuating lever. A dual function for the component can be realized in this way.

In one embodiment, the actuation of the switch may be by contacting or releasing. A particularly simple structure of the controller can be achieved.

In one embodiment, the switch is formed by an electrical switch with a movable switching element. A particularly simple structure can be realized in this way.

In one embodiment, the switch is formed by a circuit having one electrical switch contact or two electrical contacts. A component of the actuating device and / or safety device can then assume the dual function of a switching element. In one embodiment, the switch is immovably connected to the inertial member and / or may be actuated by the mechanical safety member or the external operating lever. A particularly reliable operation can be made possible.

In one embodiment, the switch is fixedly connected to the external actuating lever and / or can be actuated by the inertia element. A particularly reliable operation can be made possible.

In one embodiment, the switch may be actuated by the inertia member and the outside actuating lever and / or the inertia member and the outside actuating lever are electrically conductively connected together, preferably via a common axis for rotatably supporting the external actuating lever and inertia member. A particularly reliable operation of a switch, which is formed in particular of a circuit and the external actuating lever and the inertia element as switching elements, can thus be made possible.

In one embodiment, the holding device comprises a holding circuit, in particular a delay element, an RC element or a hold circuit. The locking device can thereby be selectively activated for the time required for locking.

In one embodiment, the switch via the electrical holding circuit acts on a load switch or circuit breaker for supplying the locking device or an electrical drive of the locking device with electrical energy. The locking device or the electric drive of the locking device can thereby be supplied specifically for the time required for locking with electrical energy for driving the locking operation. Without the electrical energy, the locking process stops. Without electrical energy can therefore not be locked. If the switch acts via the holding circuit on a load switch or circuit breaker for supplying the locking device or an electrical drive of the locking device with electrical energy, this means the following. The electrical energy is transmitted or blocked depending on the load switch or circuit breaker to the locking device or an electric drive of the locking device. The load switch or circuit breaker is in turn controlled by the switch. The holding circuit is interposed, ie between the switch and the load switch or circuit breaker. Thus, when the switch sends a signal to the load switch or circuit breaker for passing the electrical energy, the latch circuit ensures that this signal is maintained for at least the required period of time for latching, regardless of the length of actuation of the switch. In one embodiment, the above-mentioned switch may be another further load switch or circuit breaker. The locking device then comprises at least two load switches, two circuit breakers or a load switch and a circuit breaker.

In one embodiment, the holding device is configured so that the locking device can be brought motorized into a locking position when the shorter than the time required for it was actuated. In the locking position of the locking operation is carried out to the end and the locking device locked in the intended manner. The time required for this is measured from an unlocking position of the locking device or the locking operation until reaching the locking position. It can be so effectively avoided that the locking device remains in an undefined intermediate position between the unlocked position and the locking position, because the switch has not been operated long enough.

In one embodiment, the closure device includes a sensor for measuring acceleration and / or velocity. A particularly reliable locking of the locking device in the event of a crash can be achieved. A ratchet generally comprises a catch for receiving a latch bolt and a pawl for latching the catch with the latch bolt received in a skin-lock position, preferably also in a pre-latch position. Optionally, a blocking lever is provided for blocking the pawl in its locking position with the catch. The locking mechanism is preferably firmly connected to the motor vehicle door or motor vehicle door. The locking pin is then firmly attached to the vehicle body. But the reverse case is possible. A release lever, which can be actuated by a handle, for example, serves to release the pawl from the latched state with the catch to open the locking mechanism.

An actuating device generally comprises a handle for the user to open the vehicle door or vehicle door, an external operating lever and / or a release lever.

A locking device basically comprises an electric drive to lock and unlock using the electric drive. In particular, the electric drive comprises a locking motor. With the electric drive, the locking operation can be driven, so for example, a lever or latch for locking from an unlocking position are moved to a locking position. Locking by means of a locking device prevents the locking mechanism from being opened by actuating the actuating device. In order to open the lock, you must first unlock. A locking can take place in that the coupling is interrupted by an actuating element to the locking mechanism. An associated actuating element can then indeed be actuated, for example, by pivoting. However, such a movement is then not transmitted so that thereby the locking mechanism is opened, since the coupling is interrupted. For example, can be blocked by the lever or the latch, a release lever, so that the locking mechanism remains closed upon actuation of the handle or external operating lever by the user or unplanned as a result of a crash. In particular, the locking device comprises a door control device or is connected to a door control device, with which the locking and unlocking can be controlled by means of the electric drive. For example, all doors and flaps can be centrally locked and unlocked. The switching times of such door control devices are usually more than 100 ms. A locking device may in particular be a central locking system of a motor vehicle or connected to a central locking device.

Activation of the locking device may be, for example, driving the locking motor to drive the locking operation or supplying the locking motor to drive the locking operation with electrical energy.

A safety device which can prevent unscheduled opening of the locking mechanism in the case of high accelerations and / or in the case of high speeds is preferably a mechanical safety device. A mechanical safety device has the advantage compared to electrical devices, not to rely on an electrical power supply. In particular, the safety device comprises an inertia element and a mechanical safety device element movably mounted relative to the inertia element. Preferably, the inertia element and the mechanical safety element are movably coupled together by a dynamic energy storage, preferably by a spring. The inertia member is preferably an inertia lever or an inertia member. For example, it can be prevented in a mechanical manner that in the event of a crash, the release lever is pivoted for opening the locking mechanism.

A controller for activating the locking device may comprise an electrical circuit, wherein the circuit may be closed or opened by contacting or releasing an inertia element and / or by contacting or releasing a mechanical safety device element to activate the locking device. Alternatively or additionally, the Control include an electrical switch with movable switching element, which can be contacted or solved in particular by the inertia element and / or the mechanical safety element, in particular due to a high acceleration and / or high speed.

Alternatively or additionally, a control may be such that deformations occurring in the event of a crash are used directly to close an electrical circuit and thereby supply an electrical drive with the locking motor of the locking device with power and thus lock. The control device can be integrated in the actuating device. The control device may be part of the safety device, which is able to mechanically prevent opening when high accelerations are present, that is, when acceleration is excessively fast.

A controller may interact with a lever, in particular the mechanical safety device element, or may comprise a separately provided lever. In both alternatives, the lever is preferably arranged so that the lever is exposed in the event of a crash sufficiently large forces to be pivoted. This pivoting can close a circuit immediately or actuate an electrical switch, which then closes a circuit. By closing the circuit then an electric drive with the locking motor can be supplied with power, thereby the locking process is driven. Preferably, the central locking system is powered by closing the circuit so that all the doors and flaps connected to the central locking system are then locked.

In one embodiment, the lever may be held by a spring element in an initial position so that low accelerations are not sufficient to pivot the lever for locking. Only by a high acceleration of the lever can be pivoted so that thereby the locking device is activated. In particular, the spring element can Move the lever back to the starting position. If there is no obstacle or no counterforce, the spring element is able to return the lever to the starting position.

Basically possible is a mechanism that locks in the case of a high acceleration controlled by the controller. But it is preferably provided that is locked by an electric drive. Preferably, a central locking is supplied with electric power to lock in the event of a crash as possible all doors and flaps as quickly as possible.

"In the case of high acceleration" means that there is a limit for accelerations of components. Exceeding an acceleration of a designated component exceeds the limit, so there is a high acceleration.

"In the case of high speeds" means that there is a limit for speeds of designated components. If a speed of a component provided for this exceeds the limit value, then there is a high speed. An opening of the locking mechanism is thus acceleration-dependent and / or speed-dependent prevented. In addition, the locking system is locked depending on it. It is so reliably prevented that in a crash, a door or flap can open unscheduled.

The safety device, which is able to prevent unscheduled opening of the locking mechanism in the case of high accelerations, comprises in one embodiment an inertia element that does not move or at least retard in the case of a high acceleration and / or in the case of a high speed compared to a or several other components of the safety device, in particular the mechanical safety device element, and / or compared to one or more other components of the actuator, preferably the external operating lever. Alternatively or additionally, the Inertia element in the case of high accelerations and / or in the case of high speeds move differently compared to the case of low accelerations and / or low speeds. In particular, in the case of a high acceleration and / or in the case of a high speed, the outside operating lever moves with a time lag relative to the mechanical safety element.

If, due to high acceleration and / or due to high speed, the inertia element does not move or is delayed in time compared to one or more other components of the safety device and / or the actuator, then in one embodiment an electrical switch is actuated. In an alternative or supplementary embodiment, an electrical switch may be operated by the inertial member moving differently due to high acceleration and / or due to high speed as compared to the case of low accelerations and low speeds, respectively. By actuating the electrical switch, the locking device is activated. In particular, after a crash has occurred, the locking device can be activated particularly quickly, in particular within 70 ms, measured from the crash until the locking device is locked, that is, until the locking process which has been completed as intended. It can thus be made possible that a crash after Ersteinschlag sustained by an electric switch, in particular a load switch or circuit breaker, from the crash pulse directly or through the safety device, the unscheduled opening of the locking in the case of high accelerations and / or high speeds can be prevented, is switched. The switching causes an activation of the locking device, for example, sufficiently fast compared to switching by means of a door control device, which can also be electrically locked with the rule.

In one embodiment, motor terminals of a central locking system, advantageously controlled by the control device, are supplied with power from a battery to lock all doors or flaps. Regardless of the speed with which a handle is pulled, the door remains securely closed.

A mechanical safety device that can prevent opening in the event of a crash reacts within 4 to 30 ms in one embodiment. In one embodiment, a switch is actuated by means of a relative movement of an inertia element, in particular inertia lever. This switch can thus serve as a load switch directly in the lock of a locking system. In one embodiment, an end stop of an inertia element, in particular inertia lever, actuate a switch. Also, this switch can thus serve as a load switch directly in the lock of a locking system.

A load switch can be used so that the load switch operates the central locking directly, in particular from the lock, that is, e.g. powered. On the detour via the door control unit can be omitted, the switching time is about 120 ms. The central locking system can thus lock the lock within 30 to 35 ms.

Together, a switching time of 4 ms to 30 ms results as the reaction time of the mechanical safety device plus 30 ms to 35 ms as the reaction time of the central locking results in a total reaction time of a maximum of 65 ms. This means that lock allows locking before the time of "new pulses" approximately after 70 ms. In one embodiment, a separate "speed-dependent lever (80g)" arranged in the lock can also be used to actuate the central locking or to actuate a switch which activates or supplies power to the central locking. In one embodiment, the locking device is used for a so-called E-lock. These are locks, which are usually operated in normal operation, using only electric drives.

In one embodiment, a crash sensor, preferably a sensor for acceleration measurement, is provided, which in the case of a crash, an electric Circuit closes so as to lock immediately, preferably by means of a central locking. The crash sensor is housed in particular in a lock housing of the locking system. Within the lock housing then inter alia, the locking mechanism and / or one or more components of the actuator are housed. In particular, a component of the actuating device, such as an external operating lever, is connected to an outside handle via a Bowden cable or a linkage. A pivoting of the outer handle is then transmitted through the linkage to this component, ie, for example, to an external operating lever, so as to be able to open the locking mechanism without the need for electrical energy. In the lock housing, alternatively or additionally, a switch can be accommodated with which, in the event of a crash, a circuit is closed so that it is locked. In the lock housing, a battery may alternatively or additionally be present in order to be able to provide the current through the battery which is required for locking by closing a circuit provided for this purpose.

Embodiments of the invention will be explained in more detail with reference to figures. Features of the embodiments and other alternative or supplementary embodiments described below may be combined individually or in a plurality with the claimed subject matter. The claimed protection areas are not limited to the embodiments.

Figure 5: Schematic representation of a section of a closing device showing the actuating device in the unactuated initial position, the safety device, an electrical switch of the controller and the holding device according to a fifth embodiment.

Figures 1 to 5 all show an external operating lever 1 of an actuating device which is rotatably mounted by an axis 5 on a plate, not shown, or a housing of the actuating device. The plate or the housing may also be part of a tailed, not shown lock, which includes a locking mechanism 20 of the catch and pawl. The external actuating lever 1 is in particular connected via a Bowden cable, not shown, a rope or a linkage with a handle, not shown, for the user. However, the external operating lever 1 can also already be a handle of a motor vehicle door or motor vehicle door. The free end of the elongated external actuating lever 1 has as attachment for the rope, linkage or the Bowden cable an eyelet 10, for example in the form of a bore.

In Figures 1 to 5, the actuating device is in an initial position in which the actuating device is not actuated, that is unconfirmed, is. When the handle is actuated, the external actuating lever 1 is pivoted about the axis 5 in a clockwise direction by means of the cable, the linkage or the Bowden cable. Through the axis 5, a bow-like release lever 2 of the actuator and a bow-like inertia element 4, in particular inertial lever, the safety device are also rotatably mounted. On the outside operating lever 1, a mechanical safety member 3 is rotatably fixed by an axle 8.

In FIGS. 1 to 5, the safety device is in a ready state. In the standby state, the components of the safety device, ie the inertia element 4 and the safety device element 3, do not move relative to the external operating lever 1 during operation, but move with the external operating lever 1. In the standby state, therefore, the inertia element 4 and the safety device element 3 follow the movement of the external actuating lever 1 during an actuating operation and the return to the starting position of the actuating device. As long as no high acceleration and / or high speed occur, the safety device remains in this standby state.

The axis 8 of the safety device element 3 is located between and / or approximately at the level of free ends of the release lever 2 and the inertia element 4. The safety device element 3 has a long arm 6 and a short arm 7, in particular forming an L-shape. In particular, the long arm 6 is slimmer than the short arm 7. The long arm 6 is biased in particular with its free end to the inertia member 4, when the actuator is unactuated and the safety device is in the standby state. For biasing a biased spring 9 of the securing device is responsible, which is attached at one end to the inertia member 4 and with its other end on the outer lever 1. External actuating lever 1 and inertia element 4 are thus biased by a spring 9 coupled together. The inertia element 4 comprises a pawl receptacle 11, preferably in the form of an angular or L-shaped end, by which the safety device element 3 is prevented in the standby state shown, in particular to pivot in a clockwise direction. When the safety device element 3 is pivoted, the safety device is no longer in the standby state. The end angled portion of the pawl receptacle 1 1 is shorter than the distance between the short arm 7 and the release lever 2. The short arm 7 of the security device element 3 includes the long arm 6 at a right angle. The free end of the short arm 7 in the standby state adjoins the free end of the release lever 2, but has a distance 12 to this end in the unactuated state of the actuator as shown.

The mechanism of the actuator works for unlocking or opening a not shown locking mechanism 20 from the initial position in Figures 1 to 5 as follows. When a handle, not shown, is actuated, the outer operating lever 1 pivots, in particular clockwise. At normal acceleration, the inertia element 4 and the outer actuating lever 1 behave together like a rigid body due to the coupling by the spring 9. This has the consequence that during an actuating movement the

Safety device element 3 is held by the pawl receptacle 1 1 and the safety device remains in the standby state that the short arm 7 finally reaches the free end of the release lever 2 and then the release lever 2 is also pivoted in particular clockwise. By this pivoting a locking mechanism 20 is opened and that by Flerausbewegen a not shown pawl of the locking mechanism 20 from its detent position. As a result, the rotary latch, not shown, of the locking mechanism 20 is released, which then in

Can pivot opening direction. An unillustrated latch bolt, previously held by the catch, may leave the ratchet 20 so as to open an associated vehicle door or vehicle door. By such an actuation operation, no switch of the controller is actuated, and consequently the locking device 18 is not activated. The inertia element 4 and / or the safety device element 3 are thus involved in the actuation process and / or partially constitute part of the operating chain. Therefore, the safety device element 3, and in particular the inertia element 4, can simultaneously be part of the safety device and the actuating device.

At high acceleration, the external operating lever 1 and the inertia element 4 do not behave like a rigid body due to the spring coupling by the spring 9. For example, if by a crash an unscheduled actuation, ie pivoting, the external actuating lever at high acceleration and / or high speed, increases the distance between the pawl receptacle 1 1 and the external actuating lever 1, whereby the safety device element 3 and the free end of the arm 6 of the jack receptacle 1 1 is moved away. The safety device element 3 can now pivot in particular clockwise. This happens as soon as subsequently the short arm 7 reaches the free end of the arm of the release lever 2. Since the short arm 7 is shorter than the long arm 6, the free end of the long arm 6 is moved out of the engagement area of the pawl receiver 11 at a relatively high speed. The safety device element 3 does not come into engagement with the release lever 2. The release lever 2 is thus not pivoted. In the embodiments of Figures 4 and 5 - and in the embodiments of Figures 1 to 3 without taking into account the Flalteeinrichtung - slides instead the safety device element 3 over the release lever 2 of time, without pivoting it. A locking mechanism 20 is thus not opened at high acceleration.

If, however, the actuating device is actuated with a sufficiently low acceleration and / or speed, then the inertia element 4 and the external actuating lever 1 behave like a rigid body. The movable switching element 14 is then not actuated. Therefore, the locking device 18 is then activated for locking.

Since the outer operating lever 1, the trigger lever 2 and the inertia element 4 in an embodiment as shown in Figures 1 to 5 on a common axis. 5 are fixed and extend in approximately the same direction, only a small space is required. Normally, it is not necessary to engage in advance, so that a lock can be opened without problems and with very little delay by pressing it. Also, a disengaged state need not be previously released. Due to the simple structure with a small number of parts, the actuator works reliable and durable.

In the embodiments of Figures 1, 2, 3, and 5, the switching element 14 is actuated by the pivoting of the safety device element 3 at high acceleration and / or high speed, in particular clockwise about the axis 8. This moves due to the force of a prestressed spring element (not shown) in a contact in the electrical switch 13 or in a release from the electrical switch 13 out. By pressing an unillustrated circuit is closed in particular, alternatively opened, and thereby the locking device 18 is activated.

In the embodiments of Figures 1, 2 and 3, as mentioned above, a switch in the form of an electrical switch 13 is provided with movable switching element 14. The switch can be actuated to activate the locking device 18 by the movable switching element 14 is released from a contacted held state. For example, the switch can be actuated by the switching element 14 is released from a pressed-down state, that is released, is. In particular, the contacting, pressing, pressing, flipping, releasing and / or releasing takes place by the safety device element 3.

In the embodiment of Figure 1, the movable switching element 14 of an electrical switch 13 is arranged on the underside of the safety device element 3 and / or preferably laterally attached to the outer actuating lever 1, preferably on the side of the inertia element 4. A flattening device 28, 29 is provided by a latching receptacle 29th in the form of a particular rectangular Recess in the safety device element 3 and a locking element 28 in the form of a particular rectangular retaining bolt or latch bolt preferably formed with a slope. The latching receptacle 29 is provided in particular within the long arm 6 and extends parallel to the axis 8. The latching element 28 is provided above the axis 8 on the external actuating lever 1. The latching element 28 is displaceably movably guided and / or spring-biased parallel to the axis 8 of the safety device element 3 in a retaining-bolt opening 21 in the outer-actuating lever 1. When at high acceleration and / or high speed the

Safety device element 3 of the pawl receptacle 1 1 unlocked, pivoted about the axis 8, the switching element 14 releases and thereby actuates the electrical switch 13, the retaining latch or latch bolt engages in the recess or the locking receptacle 29 when the safety element 3 reaches the detent position , In the locked position, the safety device element 3 is thus secured and can neither pivot the trigger lever 2, nor pivot back to the switching element. It is thus ensured that the electrical switch 14 remains actuated. The locking device is therefore activated for a sufficiently long time to complete the locking process. By unlocking the locking device, the locking element 28 can be pulled out of the recess or the locking receptacle 29, so that the security device element 3 is moved back in particular by a return spring, not shown, and thus brings the safety device back into the ready state in which the switching element 14 is pressed is held.

In the embodiment of Figure 2, the electric switch 13 is attached to the outer operating lever 1 as in the case of Figure 1. However, the switching element 14 is now in the initial position shown on the inertia element 4. The electric switch 13 can thus be operated faster compared to the case shown in FIG. A holding device 28, 29 is formed by a latching receptacle 29 in the form of a recess, in particular with a bevel in the safety device element 3 and a latching element 28 in the form of a retaining bolt with a contour adapted to the recess. The Locking receptacle 29 is provided in particular within the long arm 6 and extends parallel to the axis 8. The locking element 28 is provided above the axis 8 on the external actuating lever 1. The latching element 28 is displaceably movably guided and / or spring-biased in a guide 22 parallel to the surface of the outer actuating lever 1 and / or radially to the axis 8 of the safety device element 3. The safety device element 3 has a holding arm 23, which extends the short arm 7 with a thinner width compared to the arm 7. If at high acceleration and / or high speed, the safety device element 3 is unlocked from the pawl receptacle 1 1, pivoted about the axis 8, the switching element 14 releases and thereby actuates the electrical switch 13, the retaining latch snaps into the recess or the locking receptacle 29, when the safety device element 3 reaches the detent position. In the locked position, the holding arm 23 keeps the inertia element 4 at a distance from the switching element 14 such that the electrical switch 13 can not be contacted by the inertia element 4 and thus remains actuated. The safety device element 3 thus ensures that the release lever 2 is not pivoted and the switching element remains loosened. The electrical switch 14 therefore remains actuated and the locking device is activated for a sufficient time to complete the locking process. By unlocking the locking device, the locking element 28 can be pulled out of the recess or the locking receptacle 29, so that the security device element 3 is moved back in particular by a return spring, not shown, and thus brings the safety device back into the ready state in which the switching element 14 is pressed is held.

In the embodiment of Figure 3, the electrical switch 13 is attached to the inertia member 4 and thus advantageously contributes to increase the weight of the inertia member 4 at. The movable switching element 14 is applied to the safety device element 3. If the distance between the inertia element 4 and the safety device element 3 is increased due to a high acceleration, the movable switching element 14 is thereby released, that is to say released. The locking device 18 is activated. A Holding device 28, 29 is formed by a locking receptacle 29 in the form of a particular round depression in the short arm 7 and a locking element 28 in the form of a particular bolt-like retaining bolt. The latching element 28 is disposed in the standby state below the long arm 6 and inserted into a recess 21 parallel to the axis 8 in the outer actuating lever 1, slidably guided and / or spring-biased. When at high acceleration and / or high speed the

Safety device element 3 of the latch receptacle 1 1 unlocked, pivoted about the axis 8, the switching element 14 releases and thereby actuates the electrical switch 13, the retaining latch engages in the recess or the locking receptacle 29 when the safety element 3 reaches the detent position. In the locked position, the safety device element 3 is thus secured and can neither pivot the trigger lever 2, nor pivot back to the switching element. It is thus ensured that the electrical switch 14 remains actuated. The locking device is therefore activated for a sufficiently long time to complete the locking process. By unlocking the locking device, the locking element 28 can be pulled out of the recess or the locking receptacle 29, so that the security device element 3 is moved back in particular by a return spring, not shown, and thus brings the safety device back into the ready state in which the switching element 14 is pressed is held.

Alternatively, in the case of Figure 3, the movable switching element 14 abut against the external operating lever 1 in the illustrated starting situation. Again, an acceleration-related increase in distance between the inertia member 4 and the outer operation lever 1 causes a release of the movable switching element 14. An activation of the locking device is thus achieved.

In the embodiment of Figure 4, the switch is formed by an electrical circuit 24 with the electrical contacts 15, 16 and components of the actuator and / or safety device. In particular The components take on the dual function of a movable switching element. The electrical circuit 24 is connected to or comprises an electrical power supply 19. In one embodiment, the switch for activating the locking device 18 can be actuated by the outer actuating lever 1 contacts or pushes the electrical contacts 16 and at the same time the inertia element 4 contacts or pushes the electrical contacts 15, as shown in FIG. In the starting position of the actuating device and in the standby state of the safety device, the electrically conductive inertia element 4 is electrically connected to the electrical contact 15. If, in the case of excessively high acceleration, the inertia element 4 is not released from the electrical contact 15 or not quickly enough due to its higher inertia compared to the external operating lever 1 and the safety device 3 attached thereto, the electrically conductive external operating lever 1 reaches the electrical contact 16 and thus includes a circuit comprising the electrical conductor 17, the locking device 18, in particular the electric drive of the locking device 18 and a power supply 19, which corresponds in particular to a battery of the closing device. In this embodiment, the inertia element 4 is electrically connected, for example via the electrically conductive axis 5 with the external actuating lever 1. If, however, the external actuating lever 1 and the inertia element 4 behave like a rigid body due to a sufficiently low acceleration, the inertia element 4 is released from the electrical contact 15 before the external actuating lever 1 makes electrical contact with the electrical contact 16. The locking device 18 is then not activated for locking the locking device.

Thus, the locking device 18 remains activated in this way long enough for an end leading the locking process, a Falteschaltung 30 is provided in the circuit 24, which ensures when activating the locking device 18 by closing the circuit that the activation of the locking device 18 at least while maintaining until the Locking device was locked, so the locking process was completed.

It is in principle possible that in one embodiment by the circuit which can be closed by the external actuating lever 1 and the inertia element 4 by means of the electrical contacts 15 and 16, the locking device 18 or the drive of the locking device 18 is supplied directly with electrical energy. An additional load switch or circuit breaker can be saved and a particularly short reaction time can be achieved.

Since the time required for locking the activation time is usually always the same or at least can be determined by an activation time, which can always lead to reliable locking, the holding circuit 30 is configured in one embodiment that upon activation of the locking device 18 by pressing the switch, the locking device 18 remains activated for the specified activation time. This embodiment can also be combined with a control which, as in the exemplary embodiments of FIGS. 1, 2, 3 and 5, provides an electrical switch 13 with a movable switching element 14 whose actuation leads to the activation of the locking device 18. In particular, the holding circuit is a delay element, an RC element or a so-called hold circuit, which is also known in English as a hold switch or holding circuit.

In one embodiment, a switch is actuated at high accelerations and / or high speeds, so that an activation signal for activating the locking device 18 is generated and / or transmitted for locking the locking device. If the holding circuit is a delay element, RC element or a hold circuit, then this activation signal is delayed in time, extended and / or maintained, in particular using a capacitor. Alternatively or additionally, a circuit is provided which activates the activation signal by means of the connection of an auxiliary power source, eg Auxiliary battery, extended or maintained. Preferably, this extension or maintenance is done automatically or is triggered by pressing the switch. The activation signal can be maintained in one embodiment until the specified activation time has been reached or, for example, the circuit for maintaining the activation signal is interrupted by a limit switch of the locking device. The limit switch is then triggered accordingly when the locking device is locked and / or when the locking position of the locking device is reached.

In particular, the switch acts via an electrical holding circuit 30 on a load switch or circuit breaker 31, which in turn closes the circuit of the drive of the locking device 18. By the holding circuit is then ensured that the locking device 18, which is in particular the central locking of the motor vehicle, and then moves to the end position or locking position or moves when the switch is pressed only briefly.

In one embodiment, a sensor 25 is provided for measuring acceleration and / or velocity. A particularly reliable activation of the locking device can be made possible. In principle, it is possible in one embodiment, which is not shown in the figures, that the switch variants shown in FIGS. 1 to 5 are omitted and replaced by the use of the sensor 25 for measuring the acceleration in the circuit 24 of FIG. The circuit 24 with the sensor 25 for acceleration measurement can then be placed together with the load switch or power switch 31, the holding circuit and in particular with an evaluation device for the sensor signals of the sensor 25 preferably on a printed circuit board or printed circuit board. In particular, the printed circuit board or printed circuit board is arranged within a lock housing of the closing device.

In the embodiment of Figure 5, a switch in the form of an electrical switch 13 is provided with movable switching element 14. The switch can for Activation of the locking device 18 are actuated by the movable switching element 14 is contacted, so contacted from a dissolved state, for example, from the security device element 3, preferably pressed, is. In particular, the contacting, pressing and / or releasing takes place by the safety device element 3.

From the inertia element 4 extends laterally a carrier 26 in the direction of the external actuating lever 1, in particular such that the carrier 26 covers the external actuating lever 1, at least in the starting position. The carrier 26 is in particular C-shaped. An electrical switch 13 with a particular spring-biased switching element 14 is mounted on the carrier 26 and points in the direction of inertia element 4. On the external actuating lever 1 is an actuating projection 27 is shown, in particular parallel to the axis 5 of the external actuating lever 1. In the initial position of the external actuating lever 1, in the actuating device is unactuated and the safety device is in the standby state, the actuating projection 27 is spaced from the switching element 14, so that the switching element 14 is released. The electrical switch 13 is arranged so that the electrical switch 13 is in the released state unactuated and in the contacted state, i. When the switching element 14 is pressed into the electrical switch 13, is actuated. A holding device 28, 29 is formed by a latching receptacle 29 in the form of the actuating projection 27 and a latching element 28 in the form of a retaining latch. The latching receptacle 29 preferably has a ramp-shaped latch contour in the direction of the latching element 28 and / or a bevel. In particular, the guide extends parallel to the surface of the external actuating lever 1 and / or radially to the axis 5 of the external actuating lever 1.

When at high acceleration and / or high speed, the safety device element 3 of the jack receptacle 1 1 unlocked and around the Axis 8 is pivoted, the actuating projection 27 moves toward the switching element 14. In this case, the actuation projection 27 or the latching element 28 displaces the latching receptacle 29 shortly before reaching the latching position, so that in the latching position the latching receptacle 29 engages behind the latching element 28 or engages. In one embodiment, the actuating projection 27 already actuates the electrical switch 13 when the detent position is reached. In another embodiment, the actuating projection 27 and the locking element 28 moves beyond the locking position until it contacts the switching element or presses and thus actuates the electrical switch 13. The actuation of the electric switch 13 is then carried out in time after reaching the detent position. In both aforementioned embodiments, the locking element 28 is held by the locking receptacle 29 in a contacting state with the switching element 14, that the electrical switch 13 remains actuated. The locking device 18 is thus activated for a sufficient time to complete the locking process. By unlocking the locking device, the locking receptacle 29 deflected and the locking element 28 are released so that the safety device can again assume the ready position.
