Locking device for a flap of a vehicle, method of operation

The invention relates to a locking device for a flap of a vehicle, in particular for a front door of a motor vehicle, with a lock that locks the flap in its closed position and this one with an actuable pawl

cooperating catch for locking and releasing a flap associated with the closing element, with a pivotable catch hook which catches in its catching position released by the catch locking element in a gap opening position of the flap, and with a Bowden cable for actuating the locking device.

Furthermore, the invention relates to a method for operating such

Locking device.

Locking devices of the type mentioned are known from the prior art. In order to prevent unauthorized opening of flaps or doors, especially in motor vehicles, this is usually associated with a locking device which locks the flap in its closed position. Conventional locking devices have for this purpose a lock comprising a catch and a cooperating with this pawl. In the locked state, the rotary latch locks a closing element of the flap, wherein the rotary latch is usually spring-loaded in the direction of its release position. In order to keep the catch in its locked position, it locks with or on the pawl which holds the catch in the locked position against the spring force. By pressing the pawl and the subsequent release of the latch, the catch is released and the flap can be opened. For flaps of vehicles that open to the front, whose

Swivel axis is thus seen in (forward) driving direction behind, an additional safety mechanism is needed, which prevents improper operation of the locking device, the flap is fully opened by the wind. This is the case in particular with hoods and vehicles, the trunk of which is arranged at the front of the vehicle. To secure it is known to provide a pivotable fishing hook, which catches the released of the catch in a catching position in a gap opening position of the flap. The fishing hook allows in its catch position thus opening the flap only to the gap opening position, in which the flap is usually urged by a spring element. Another or complete opening of the door is only possible if the catch hook is released from the closing element. This can be done either by pivoting the closing element or by re-actuation of the locking device, as disclosed for example in the published patent application DE 10 2009 010 975 A1. The locking device disclosed therein is actuated by a Bowden cable.

The invention has for its object to provide a locking device and a method for their operation, which allow a simple complete unlocking or releasing the door.

The object underlying the invention is achieved by a locking device having the features of claim 1. It has the significant advantage that it can fully release the flap by just one operation. For this purpose, it is provided that the pawl and the catch hook in opposite directions in each case against a spring force in their respective release division are displaced, in particular pivotable, wherein a soul of the Bowden cable with the pawl or with the fishing hook and one end of a shell of the Bowden cable according to the fishing hook or are operatively connected to the pawl so that upon actuation of the Bowden cable of the fishing hook and the pawl are forced into their release division. According to the invention, it is thus provided that the Bowden cable is connected both to the catch hook and to the pawl of the lock in order to actuate both at the same time. This ensures that released by an operation of the Bowden cable, the catch and the fishing hook is removed from its catch position, so that the flap can be fully opened after a single actuation of the locking device. In order to prevent an undesirable complete opening of the flap during operation, the catch hook is preferably associated with a separate, in particular vehicle speed-dependent working safety device.

Preferably, the sheath of the Bowden cable to that with the pawl or

Catch hooks connected end following a curvature. The curvature leads as

Deflection element to the fact that the soul rests on the inside of the shell and thereby at

Actuation of the Bowden cable generates laterally acting forces on the end, which cause the pawl and fishing hooks are urged in opposite directions.

Conveniently, the core is arranged to extend, after curvature, at an angle to the portion of the soul between the point of attachment of the core to the pawl and the end of the sleeve to the fishing hook. Here, the principle "action equal reaction" is exploited.This is to be explained by the following example: The soul is connected to the pawl and the end of the shell with the fishing hook.Thus the soul runs from the pawl through the arranged on the fishing hook shell and through the curvature, when the soul is pulled, the soul pulls directly on the pawl the attachment point of the soul formed on the pawl spaced from its axis of rotation, so that a lever action is generated, which converts the pulling movement of the soul in a rotational movement of the pawl. Since the pawl is spring-loaded and counteracts this spring force of the tensile force, the soul is urged due to the angled course or due to the deflection in the curvature against the inside of the sleeve. The greater the spring force is designed, the greater the force with which the soul is pressed laterally in the curvature against the sleeve. The lateral contact force of the soul and the spring force thus correlate with each other. If the catch hook immovable, the soul will only support the curvature of the sleeve, and the pawl is actuated. If the catch hook is not hindered in its rotational movement, then the lateral contact force of the soul acts in the curvature against the spring force of the spring acting on the catch hook. By an appropriate interpretation of the pawl and the fishing hook associated springs can thus be achieved that upon actuation of the Bowden cable, that is applied to the soul tensile force, the pawl by the tensile force of the soul and the fishing hook by the side contact pressure of the soul the curvature simultaneously urged against the respective spring action

or relocated. The same applies to an embodiment in which the soul is connected to the fishing hook and the shell with the pawl. If one of the parts is hindered in its movement, nevertheless the other part is movable or rotatable. Due to the advantageous embodiment, the displacement of the pawl and the catch hook in a simple manner in opposite directions with only one

Actuator allows.

To ensure this function safely, the sheath of the Bowden cable preferably has a stiffening at least in the region of the curvature. This is always the case

Presence of the curvature and in relation to the section between the pawl and fishing hook angled course of the soul guaranteed. In principle, instead of a curvature of the sleeve, another deflection element may be provided at the end of the sleeve, such as a deflection roller, a deflection cylinder or the like, about which the soul in particular at a certain predetermined angle of the pawl or the

Arrived fishing hook coming deflected into the sleeve.

According to an advantageous embodiment of the invention it is provided that the catch hook has a driving lever which is pivotally mounted up to a fishing hook stop relative to the fishing hook and firmly connected to the soul or the end of the shell of the Bowden cable. The fishing hook is thus designed in several parts, wherein the connection according to the invention with the Bowden cable takes place in that the soul or the end of the shell are firmly connected to the driving lever. The entrainment element is up to that Fanghook stop pivotally mounted relative to the catch hook. At the fishing hook stop it is positively on the fishing hook to take the fishing hook in a further displacement of the driving lever - as already mentioned above. The catch hook can thereby be pushed or moved by the driving lever in the desired direction, on the one hand, and on the other hand, it can also be detached from the

Mitnahmehebel be shifted in this direction, which in particular when closing the flap has advantages, since in this case the fishing hook can be automatically pushed from its catching position by closing the flap, if he has a corresponding

Operating slope or -Kulisse has on its side facing the flap.

The catch hook and the entrainment element preferably have a common first axis of rotation. Optionally, the axis of rotation is also an axis of rotation of the rotary latch.

As a result, a particularly compact locking devices is offered, which requires only a small space.

The pawl of the lock preferably has a second axis of rotation arranged parallel to the first axis of rotation. The pawl is thus arranged adjacent to catch hook and driving lever and in particular to the catch. The pawl and the catch hook are thus pivotable about two adjacent axes of rotation, wherein the

Attachment points for the soul and the shell are arranged at the catch hook or the pawl spaced from the respective axis of rotation, in order to produce a lever effect upon actuation of the Bowden cable. Due to the parallel arrangement of the first and second rotational axis is avoided that upon actuation of the Bowden cable transverse forces on pawl and fishing hooks arise, which could lead to increased friction and thus to a more difficult operation of the locking device.

According to an advantageous embodiment of the invention it is provided that the

Mitnahmehebel a pivotable locking lever is associated, which engages spring-loaded on the driving lever in the release position of the fishing hook to lock the fishing hook in its release position. Thus the fishing hook after pressing the

Locking means by means of the Bowden cable remains in its release position, so that the flap can be fully opened, even after the tensile force has been removed on the Bowden cable, the fishing hook is locked in its release position. This is the

Spring-loaded locking lever engages engaged on the driving lever, so that the catch hook or the driving lever remains in a release position. The locking lever is preferably acted upon by a spring element always in touching contact with the driving lever and is displaced by the pivoting movement in the locking position. By operating the locking lever in particular by pivoting the locking lever contrary to the spring force out of the detent position, the catch hook can be released again, so that it is spring-loaded back into its catch position.

Preferably, the locking device has an actuatable actuator which brings an actuating element into engagement with the pawl and / or with the catch hook for releasing the locking lever from the latching on the driving lever and / or for locking the catch hook in its catching position. The above-described release of the locking of the locking lever can thus be achieved by means of the actuator or by means of actuatable by the actuator actuator in a simple manner. In particular, that is

Actuating element designed as a linearly movable plunger. Preferably, the actuating element has a link, which with one end of the locking lever in such a way

cooperates, that this is released from its rest position. To lock the

Fanghakens in the fishing position, the actuator or the plunger is moved up to the fishing hook when it is in its catch position. In this case, the plunger preferably acts in a form-fitting manner with a stop of the catch hook, so that it can not be pivoted out of its catch position. In this case, the catch hook is urged with its stop against the plunger upon actuation of the Bowden cable, but prevented from pivoting. However, this does not prevent the pawl is released by means of the Bowden cable from its locking the catch position, so that upon actuation of the Bowden cable unlocking the lock is still possible, however, the flap can only be spent in its gap opening position. The arrangement of the Bowden cable according to the invention allows, as already mentioned, that catch hook and pawl are also independently operable when one of these elements on a

Pivoting is prevented. Thus, it is possible in a simple manner by means of the actuator to continue to ensure the safety function of the fishing hook in operation of the vehicle. In particular, the actuator is actuated vehicle speed dependent. Exceeds the

Vehicle speed a predetermined value, so the actuator moves the

Actuator such that the fishing hook is locked in its catch position. Below the limit speed, the actuator releases the catch hook to allow complete opening of the flap by a single operation of the Bowden cable. To the fishing hook when closing the flap or when crossing the

Limit speed at not fully open flap to spend in its catch position, the actuator is moved accordingly to the locking lever from his

Releasing latching, so that the catch hook by spring force in its catch position

zurückschwinkt. The actuator and its actuator thus form the aforementioned safety device, with which a complete release of the flap can be safely prevented in case of need. Conveniently, the locking device also comprises an operatively connected to the Bowden control element for actuating the locking device. The

Operating element, which is designed in particular as an operating lever or pull knob and facilitates the operation of the locking device for a user, is particularly preferably arranged in a door region of the motor vehicle such that it can only be reached when the door is open. As a result, a complete opening of the flap while driving the vehicle is also prevented. The control element may alternatively be arranged in the trunk, so that a person enclosed therein can be freed from the trunk in a simple manner.

The inventive method with the features of claim 10 provides that detects an actual vehicle speed and in dependence of the detected

Vehicle speed actuates the actuator or the catch hook locked in its catch position or the locking lever is pivoted to release the locking. As a result, depending on the vehicle speed, the securing function of the catch hook is ensured or restored, as already described above, so that unintentional complete unlocking or opening of the flap can be prevented or prevented.

In the following, the invention will be explained in more detail with reference to the drawings. Show here

FIG. 1 shows a locking device in the locking position,

FIG. 2 shows the locking device in a partially unlocked position,

Figure 3 shows the locking device in fully released position and

4 shows the locking device in a gap opening securing position.

Figure 1 shows a locking device 1 for the front door, in particular for a hood or for a trunk of a motor vehicle. The locking device 1 has a flap associated with the closing element 2 in the form of a striker, which is locked on the body side by the locking device 1. For this purpose, the

Locking device 1 further comprises a rotary latch 3, which holds the closing element 2 in a form-fitting manner in the closed position of the flap. Rotary traps are known to those skilled in principle, so that their training and function at this point should not be discussed in more detail. With the catch a pawl 4 cooperates. The pawl is as formed on two-sided lever which is pivotable about an axis of rotation 5. The end of a lever arm 6 is latched to the catch 3, to keep them in their locking the locking element 2 position. The locking is designed so self-locking that without the action of forces from the outside, the locking is not solvable. The end of the lever arm 6 opposite lever arm 7 of the pawl 4 is fixedly connected to one end 8 of a sheath 9 of a Bowden cable 10. If the catch is released from the rotary latch 3, then a spring 1 1 urges the closing element 2 out of the rotary latch 3, as a result of which the rotary latch 3 is rotated in the clockwise direction in the present exemplary embodiment until it releases the closing element 2. To secure the latch, the pawl 4 is spring-loaded, wherein the spring is not shown. The spring is operatively connected to the pawl 4 such that the lever arm 6 is biased in the direction of the rotary latch 3. To release the latch thus the pawl 4 has shifted against the spring force

or be pivoted. The rotary latch 3 and the pawl 4 together form a lock for the closing element. 2

Furthermore, the locking device 1 has a catch hook 12 which captures the closing element 2 in its illustrated catch position when it has been released by the rotary latch 3, so that the flap of the vehicle is held in a gap opening position and prevented from further opening. The fishing hook 12 is spring loaded in the direction of its catch position, as shown, acted upon. The flap is preferably urged by at least one further spring element in the gap opening position or in the opening direction. The tentacle 12 is arranged pivotably mounted about a rotation axis 13 which is arranged parallel and spaced from the axis of rotation 5. The fishing hook 12 is also formed as a two-sided lever, of which a lever arm 14 with the closing element 2, as described above, cooperates. Thus, the lever arm 14 at its free end a stop 15 as a rear handle, which cooperates with the striker in the catch position. The opposite lever arm 16 of the fishing hook 12 has a fishing hook stop 17 at its free end. The catch hook 12 also has a driving lever 18, which is also mounted pivotably about the axis of rotation 13. The driving lever 19 is formed substantially as a one-sided lever, wherein the free end of its lever arm 18 is fixedly connected to one end of a core 20 of the Bowden cable 10. Between the free end and the axis of rotation 13, the lever arm 19 has a pointing in the direction of the lever arm 16 and the fishing hook 12 projection 21 which rests in the illustrated locking position on the fishing hook stop 17. The driving lever 18 can thus be pivoted maximum to reach the fishing hook stop 17 relative to the fishing hook 12. Furthermore, the driving lever 18 is assigned a locking lever 22. The locking lever 22 is pivotally mounted about an axis of rotation 23 which is parallel and spaced from the axis of rotation 13. The locking lever 22 is formed as a two-sided lever, wherein a lever arm 24 has a latching projection 25 and the other lever arm 26 at its free end a

Actuating cam 27. In the locking position, as shown, the locking lever 22 is located with its the driving lever 18 facing side of this to that further displacement of the driving lever 18 is prevented in the locking direction. As a result, the maximum achievable by the fishing hook 12 locking position by the fishing hook stop 17, the driving lever 18 and the locking lever 22 is set. On the further function of the locking lever 22 will be discussed in more detail later.

The Bowden cable 10 is thus connected by its soul 20 with the driving lever 18 and the end 8 of the shell 9 with the pawl 4. On the end 8 of the shell 9 is followed by a deflection of the core 20 in the form of a preferably rigid curvature 28 of the shell. 9

Alternatively, the sheath 9 and / or the core 20 may, for example, also be guided and deflected by a pipe angle which follows the end 8 and is arranged on the pawl.

Now, if the Bowden cable 10 by means of a corresponding control element (not shown) operated so that the soul 20 is pulled in the direction of arrow 29, so are due to the curvature 28 of the shell 9 and the spring action of the pawl 4 and the tentacle 12, the lever arms 7 and 19 in the direction of the arrows 30 toward each other, that is pivoted or moved in opposite directions. As a result, the lever arm 6 is released from the catch in the direction of the arrow 31 by the catch 3, as shown in FIG. At the same time the lever arm 19 of the driving lever 18 is pulled by the soul 20 to the pawl 4, wherein the driving lever 18 entrains the fishing hook 12 and pivoted about the axis of rotation 13 in the direction of arrow 32, since the projection 21 is in abutting contact with the fishing hook stop 16 , As a result, the stop 15 of the catch hook 12 is moved from the catching position, as shown in Figure 1, in the release position, as shown in Figure 2. Since the rotary latch 3 is no longer locked by the pawl 4, as shown in Figure 2, the spring 1 1 urges the closing element 2 in the direction of the arrow 33 out of the lock, so that the rotary latch 3 is rotated in its release position, such as shown in FIG. The closing element 2 or the flap having the closing element 2 can thus be completely removed or opened.

By the operation of the Bowden cable 10 and the pivoting of the catch hook 12 in its release position, the driving lever 18 moves away from the locking lever 22 and from the lever arm 24, as shown in Figure 2. But since the locking lever 22 is also spring-blown, in such a way that it with its lever arm 24 in the direction of Driving lever 18 is urged, as indicated by an arrow 34, the

Arretiervorsprung 25 of the lever arm 24 in a latching receptacle 43 of the lever arm 19 of the driving lever 18 spent, as shown in Figure 3. The latching thus formed acts self-locking, since the driving lever 18 is urged by the spring-loaded catch hook 12 against the locking lever 22, so that the latching is maintained.

This ensures that after a single operation of the Bowden cable 10 and the corresponding operating element, the locking device 1 remains fully open and the flap can be fully opened. The

Locking device 1 thus makes it possible by only a single operation of a

Operating element to make the complete release of the flap.

As can also be seen from FIGS. 1 to 4, the locking device 1 has an actuatable actuator 35, which moves an actuating element 36, which is designed as an actuating tappet 37, linearly as required. The actuating plunger 37 has at its free end a link 38, which with the fishing hook 12 and / or with the

Actuating cam 27 of the locking lever 22 is engageable.

If, starting from the locking position according to FIG. 1, the actuating tappet 37 is moved by the actuator 35 in the direction of the catch hook 12, according to the arrow 39, the end of the actuating tappet 37 comes into abutting contact with a stop 40 of the catch hook 12. The stop 40 is aligned in the direction of rotation, so that is prevented by the lateral introduction of the actuating plunger 37 under the stop 40, as shown in Figure 4, the fishing hook 12 at a pivoting about the rotation axis 13. In Figure 4, the driving lever 18 and the locking lever 22 are not shown for reasons of clarity. The gate 38 and the end of the actuating plunger 37 is designed such that in the locked state of the catch hook 12, as shown in Figure 4, the catch is still pivotable in its release position. Now, if the Bowden cable 10 is operated as before, the fishing hook 12 is prevented from pivoting and only the pawl 4 is released from the catch 3. The closing element 2 thereby releases from the rotary latch 3 and is urged by the spring as before in the direction of the arrow 33 in the open position. However, since the fishing hook 12 is still in its catching position, the closing element 2 is caught in its opening movement by the fishing hook 12, so that it is not completely detachable from the rest of the locking device 1. Since the flap is urged in the opening direction by the spring described above, the flap thus lingers in a gap opening position. Another opening of the flap is initially not possible. The method described above is preferably carried out by a control device which is assigned to the locking device 1 and drives the actuator 35. If a lever 41 is assigned in the closing element 2, as shown in the figures, the striker can be pivoted out of the catching position on the catching hook 12 in the direction of an arrow 42, so that the flap can be completely opened.

During operation, the vehicle speed is preferably monitored and, when a predefinable limit speed of, for example, 5 km / h is exceeded, the actuating tappet 37 is brought into stop position with the catch hook 12 as described above, so that the flap can not be completely opened while the vehicle is moving. This prevents, for example, that at high speeds and a careless operation of the control element or the Bowden cable 10, the flap completely unlocked and by the

Fahrtwind is fully opened.

The locking device 1 is in its fully open position, as shown in Figure 3, so another section of the gate 38 is used to that in his

Release hook catch 12 to be released from the lock. For this purpose, the gate 38 cooperates with the actuating cam 27 of the locking element 22 such that when the actuating plunger 37 is displaced in the direction of the fishing hook 12 and the locking lever 22 according to arrow 39, the locking lever 22 is pivoted against the spring force or against the direction of the arrow 34 , so that the locking projection 25 moves out of the locking receptacle 43 and thereby the locking of the locking lever 22 is released. Due to the spring loading of the fishing hook 12 is then pivoted back into its catch position, whereby the driving lever 18 reaches its initial position shown in FIG.

The actuator 35 is thus actuated to prevent complete unlocking of the locking device 1, or to release the locking hook 12 holding in its release position locking. The latter is preferably carried out when the locking device is to be completely locked again, or when, after the Bowden cable 10 has been operated, the limit speed is exceeded and the closing element 2 is not yet outside the capture range of the fishing hook 12, so that during the acceleration of the vehicle the fishing hook 12 is moved back into its catch position to prevent further opening of the flap.

In addition, the position of the fishing hook 12 and the rotary latch 3 or further elements of the locking device 1 can be detected during operation by means of suitable sensors. For reasons of clarity, however, such sensors are not shown. Of course, unlike the embodiment described above, it is also conceivable to fasten the core 20 to the pawl 4 or to its lever arm 7 and the end 8 of the casing 9 to the lever arm 19 of the driving lever 18. In contrast to the manual operation of the Bowden cable 10 described above, it is also conceivable to actuate this electromechanically by a corresponding actuator, possibly also hydraulically.

In a closing operation in which the flap is to be locked to the body, the closing element 2 is first urged against the free end of the lever arm 14 of the fishing hook 12. Since the free end is curved, the fishing hook 12 is pivoted in the direction of the arrow 32 and after passing through the stop 15 by the

Fedbescheaufschlagung shifted back. The closing element 2 is further pressed into the catch until it locks with the spring-loaded pawl 4 and the

Locking device 1 is fully locked again.
