Description

  • The invention relates to a locking device for a vehicle door, in particular for a motor vehicle front flap, according to the preamble of claim 1.
  • For fixing in its fully closed position, a vehicle door on the body side is usually associated with a lock catch that can be locked by a pawl, which can fix a door-side closing element in a closed position and release it in a release position. To increase the ease of use of the vehicle cooperating with the catch pawl is usually operable for opening the lock via a cable from the interior of the vehicle, so that a driver can initiate the opening process of the vehicle door without leaving the vehicle.
  • In order to meet the high requirements in the field of motor vehicle safety, the vehicle door may not open completely immediately as a result of actuation of the cable from the vehicle interior, for example, opened at high speed vehicle front doors affect the view of the driver and thus a high security risk can represent.
  • Therefore, vehicle front flaps are transferred as a result of operation of the cable first in a latching position and not directly in the full release position. In this intermediate detent position, the front flap is usually in a slightly raised position, in which the door-side closing element is still held by the catch. For complete opening of the front door, the driver must leave the vehicle and operate, for example, arranged in the area of the motor vehicle front bumper, additional, released in the intermediate detent position of the front door actuator. Since the arrangement of such an actuator varies depending on the vehicle type, the actuator must often be sought by "blind" scanning.
  • Such a lock is for example from the DE 199 37 405 A1 known, where in addition to the operable from the vehicle interior pawl still a latch is provided. After the catch has left its closed position due to an actuation of the pawl, the latch can lock the catch in a different position, the intermediate latching position. In this way, a direct pivoting of the catch is to be prevented in its release position.
  • Such a lock is also from the DE 42 24 982 C1 known, where there is a Haupttrastsperrklinke operated from the vehicle interior and a separate, non-coaxially arranged, but spatially spaced Vorrastsperrklinke, the catch can lock in a Vorraststellung.
  • The DE 43 13 570 A1 also shows a similar lock with a conventional pawl for fixing the catch in a main latching position. In addition, the rotary latch on an opposite side of a linkage system is assigned, which can block the catch in a latching position and is manually operated.
  • Finally, the reveals DE 90 06 995 U1 a lock with a catch, which has a catch hook-like leg. This, at least in one embodiment of the rotary latch associated with the hook means can serve to lock the lock catcher in the unlocked state of the castle.
  • For final release of the catch, the driver must leave his vehicle and operate the latch from the front of the vehicle. By the additional latch is thus achieved that the driver does not accidentally open the front door at high speeds by accident from the vehicle interior ago.
  • However, the requirement to have to leave the vehicle for a full opening of the front door, increasingly considered uncomfortable and disturbing, so that in the meantime printed documents unassailable considerations, the front door of a motor vehicle by pressing the same cable twice from the vehicle interior of the vehicle forth in a to move completely open position.
  • The principle of such considerations should be discussed here with reference to the schematic 1 to 3 be explained.
  • 1 shows a schematic side view of a front of a motor vehicle above the front bumper arranged locking device 110 with a body-side rotary latch 114 , The catch 114 sets in the illustrated closed position a leg shown in three different positions 112 a striker for the sake of clarity, not shown motor vehicle front door. The front flap, not shown, is in the illustrated position of the locking device 110 completely closed.
  • The catch 114 is in the illustrated closed position at a first contact surface 132 from a locking pawl located in its locking position, shown broken off 116 locked. After a first actuation of a merely schematic shown cable 129 in the pulling direction Z by the driver of the motor vehicle from the interior of the vehicle forth, the pawl 116 against the pivoting direction A about its pivot axis 115 in a release position according to 2 convicted and the catch 114 hereby released. The catch 114 can now pivot with respect to the figures clockwise spring biased in the direction of pivot B.
  • Because the pawl 116 is biased with respect to the figures in the counterclockwise direction in the pivoting direction A, performs a termination of the operation of the cable 129 to that the pawl 116 from its release position according to 2 in their locking position according to 3 swiveled back. After taking their locking position, the pawl 116 evidenced 3 with a second contact surface 133 the catch 114 interact and the catch 114 Lock in the illustrated intermediate catch position. The locking device described is thus at a single operation of the cable 129 in a latching position according to 3 transferred, in which the front flap, not shown assumes a slightly raised position. The thigh 112 the striker is still in this position of the catch 114 held so that the front door does not release the engine compartment below it.
  • Even if by the described, not writable device 110 already increases the ease of use and a component savings can be obtained by eliminating an additional latch, so here there is the danger of unintentional opening of the vehicle door. The vehicle door is in an opening operation namely only in their latching position according to 3 locked when the driver pulls the cable, starting from 1 , once, briefly pressed and the pawl 116 then immediately in their locking position according to 3 can return. However, should the driver keep the cable from inside the vehicle permanently (or unintentionally), or at any rate for a longer period of time, the pawl will become activated 116 according to their release order 2 convicted and remains there. In this case, the second contact surface 133 the catch 114 at a pivoting of the catch 114 in the direction of pivot B not from the pawl 116 be contacted so that the catch 114 from its closed position according to 1 pivoted directly into its release position without being locked in its intermediate catch position. Thus, the vehicle door can be fully opened in a single, continuous operation of the cable, which, for example, at high speeds to a high security risk, z. B. by an impairment of the field of view of the driver can lead.
  • Based on the not writable prior art according to the 1 to 3 The object of the invention is to increase the safety of the device described, without restricting their ease of use.
  • The invention solves this problem with the features of claim 1 and is accordingly characterized in that the locking device has a lockingly coupled to the pawl locking device which provides a blocking surface, which can be contacted at befindlichem in release position pawl for blocking the catch with a holding surface of the rotary latch is.
  • The principle of the invention is therefore to provide a locking device which prevents pivoting of the catch when the pawl is in its release position and the catch is on its way from the closed position to the intermediate latching position. This prevents the vehicle driver can fully open the vehicle door by a single, sustained actuation of the pawl. It is now necessary to actuate the pawl for a complete opening of the vehicle door at least twice.
  • The blocking surface in this case assumes a blocking or a releasing position in dependence on the position of the pawl. In this way it can be prevented that, in a continuous operation of the pawl, by which the pawl is held in its release position, the catch can pass from its closed position directly into its release position. The blocking surface of the locking device can contact the catch namely before exceeding their intermediate catch position and thus lock the catch in a securing position. This securing position of the rotary latch preferably differs from the intermediate locking position.
  • The locking device can block the catch in this way until the pawl can leave its release position after completion of the ongoing operation and can return to a locked position. Now, the locking device can release the catch, so that the catch is transferred to its intermediate catch position in which it can be locked by the displaced in the locking position pawl.
  • It should be noted that the locking device coupled to the pawl is provided only as a backup in the event that the pawl is actuated over a longer period. In particular, it is conceivable that the blocking surface of the locking device does not block the rotary latch at all as a result of an actuation of the locking pawl, For example, if the driver has operated a cooperating with the pawl cable in a proper manner only very short and the pawl was immediately shifted back into its locked position due to their preload. In such a case, the locking of the catch in its safety position is not necessary because the catch can be locked in its intermediate catch position of the zurückverschwenkten pawl. In other words, the locking device ensures that the catch can always be locked by the pawl when it reaches its intermediate catch position.
  • The gear coupling between the locking device and the pawl is preferably achieved in a mechanical manner. The decisive factor here is that the blocking surface can contact or release the catch as a function of the position of the pawl. Instead of a mechanical motion coupling is therefore also another type of gear coupling, for example, a coupling by optical or electronic signal transmission conceivable in which a position detection of the pawl takes place and the position of the locking device is automatically changed in response to the detected pawl position.
  • In the locking device according to the invention, the rotary latch is preferably arranged on the body side and cooperates with a vehicle door-side closing element, which may be formed for example as a U-shaped striker. In principle, however, a reverse arrangement of the rotary latch and closing element and the use of other closing elements, such as locking bolts, etc., conceivable.
  • In its closed position, the catch can be locked by the pawl such that the closing element is fixed in the mouth of the catch and the vehicle door is thus locked relative to the vehicle body. The catch is pivotable from its closed position into its angular offset, also referred to as catch position intermediate latching position and there lockable by the pawl. It assumes a position in which the striker is held in the opening direction of the vehicle door of the catch. The vehicle door can now be located, for example, in a partially open position, in which it can not be completely opened due to the held striker. However, it is also conceivable that the vehicle door does not release an opening when the catch is in the intermediate catch position. In particular, but not necessarily, the vehicle door has a different position when the catch is in the closed position and when the catch is in the intermediate catch position.
  • The catch may have a hook-shaped rotary latch leg, which ensures that the striker can not escape in the intermediate catch position in the opening direction of the vehicle door from the catch. It is alternatively conceivable that the striker can be kept in the intermediate detent position of a conventional, no catch hook rotary latch, as far as the displacement angle between the located in the closed position of the catch and the catch in the intermediate catch position is only correspondingly low.
  • From the intermediate locking position, the vehicle door can preferably be returned to its closed position by conventional manual pressurization or with electronic aids.
  • The pawl can lock the catch both in its closed position and in its intermediate catch position and can be transferred to release the catch in each case in a release position. The two positions of the pawl, in which it can lock the catch, are here advantageously identical, so that the pawl between a release position and a locking position is adjustable. However, it is also conceivable that the pawl has two different locking positions, the z. B. are angularly offset from one another, so that the pawl in a first locking position lock the catch in the closed position and can lock the catch in the intermediate catch position in a second locking position.
  • For the purposes of this patent application, the term "vehicle door" is to be understood as meaning any component of a vehicle which is suitable for opening a vehicle opening, that is to say, for example. As a body-side opening or opening in the vehicle interior, to close and release again when actuated. In a vehicle door may therefore, for example, to a front or tailgate of the vehicle, but also to a side door or alternatively to a valve disposed in the vehicle interior flap, such. B. a flap of a glove box, act.
  • According to an advantageous embodiment of the invention, the contacting of the blocking surface with the holding surface prevents a displacement of the rotary latch from the closed position to the release position. As a result, the security of the locking device is increased overall and prevents a driver obtains a complete opening of the vehicle door by a single, sustained actuation of the pawl. The contacting of the blocking surface with the holding surface preferably prevents a displacement of the rotary catch from the closed position into the intermediate catching position. This prevents the catch from starting from its closed position, its latching position reached as long as the pawl is still in its release position. The blocking surface can thus block the catch until the pawl returns to its locking position, in which the pawl can prevent pivoting of the catch beyond the intermediate latching position. In principle, however, it is also conceivable that the blocking surface only contacts the catch when the catch reaches its latching position. In such a case, the intermediate catch position of the catch corresponds to its securing position.
  • According to a further advantageous embodiment of the invention, the rotary latch on a first contact surface which is contactable for locking the rotary latch in its closed position of the pawl. The catch is thereby locked in the closing position defining the closed position of the pawl. Advantageously, the rotary latch has a second contact surface, which can be contacted by the pawl in order to lock the rotary latch in its intermediate latching position. This ensures that the catch can be locked in different positions of the same pawl. An additional latch is therefore superfluous.
  • The catch can therefore be contacted in the closed position by a locking surface of the pawl on a first contact surface and pivot after release by the pawl in its intermediate catch position, in which the pawl returned from its release position can contact the catch on a second contact surface for locking in the intermediate catch position , The pawl can take on contacting the first contact surface in particular the same locking position, as in contacting the second contact surface, so that the first and second contact surface are each contacted by the same locking surface. However, the two locking positions can also differ from each other, wherein the pawl can provide two different locking surfaces.
  • Advantageously, the second contact surface forms the holding surface. This allows a particularly simple embodiment of the rotary latch. The second contact surface of the rotary latch thus has a dual function, since it can be contacted both for blocking the catch from the separate locking surface, as well as in the intermediate locking position of the pawl.
  • According to another advantageous embodiment of the invention, the locking device is designed as a lever element. In this way, a particularly simple displacement of the blocking surface can be achieved. Due to the design of the locking device as a lever element, a mechanical movement coupling between locking device and pawl can also be formed in a particularly simple manner.
  • Advantageously, the lever element is designed to be pivotable, whereby a particularly störungsunanffällig storage of the locking device is achieved. Alternatively, however, a linearly displaceable lever element is conceivable.
  • According to a further advantageous embodiment of the invention, the lever element has a first arm, for providing the blocking surface, and a second arm, for coupling with the pawl on. In this way, a particularly simple construction for achieving a comfortable coupling with a pivotable pawl is achieved. For example, a shift of the pawl into the release position can lead to a displacement of the blocking surface in the path of movement of the pivoting rotary latch. On the other hand, a pivoting of the lever element can cause a pivoting of the pawl.
  • Advantageously, the lever element has a cam, which engages for coupling with the pawl in a gate of the pawl. In this way, a particularly secure coupling between the locking device and the pawl is provided. The cam can in this case walk along during a pivoting of the lever part or the pawl in the backdrop. According to an alternative advantageous embodiment of the invention, the pawl has a mouth and the lever member on a nose, wherein the nose of the lever element engages for coupling with the pawl in the mouth of the pawl. As a result, a coupling of pawl and lever element can be achieved in a particularly simple way. The mouth can in this case in particular have a circular arc-shaped contour, in which the rounded nose of the lever element can engage particularly effectively.
  • According to an advantageous embodiment of the invention, a cable is provided for actuating the pawl. This allows a comfortable operation of the pawl. In particular, the cable can be designed as a Bowden cable. The cable can either attack directly on the pawl, or actuate this indirectly, for example via an arm of the lever element.
  • Advantageously, the cable from the vehicle interior of the motor vehicle is operable forth. This allows a high degree of operating comfort of the locking device. Thus, a driver sitting on the steering wheel of the vehicle can open the front flap of the vehicle without having to leave the car. For this purpose, the cable in the interior of the vehicle usually has an actuating element in the manner of a switch, handle or similar. In order to avoid intentional misuse of the opening function of the vehicle door from the vehicle interior ago, the additional safety devices may be assigned to the actuating element accessible from the vehicle interior, which provide, for example, that the actuator is operable only at very low speeds or stopped motor. In this context, the arrangement of a triggering of the actuating element preventing locking button is conceivable.
  • In certain installation situations, it is basically also conceivable that the pawl is additionally or alternatively operable via a cable operated from the vehicle outside.
  • According to an advantageous embodiment of the invention, the cable pull on the lever element. As a result, an optimal geometry of the locking device is achieved. In particular, the lever element may have on its second arm, which serves to couple with the pawl, an extension to which the cable or the Bowden cable is attached. Alternatively, the lever element may also have a third arm on which the cable pull acts. By operating the cable can be done in this way, both an actuation of the pawl and a displacement of the blocking surface in the path of movement of the rotary latch.
  • Alternatively, the cable can also attack directly on the pawl.
  • According to a further advantageous embodiment of the invention, a leg of the catch is formed catching hook-shaped. In this way, the vehicle door-side closing element can be kept particularly secure at lockable in intermediate latching position catch. In particular, the rotary latch leg may be hook-shaped, which faces the vehicle door in its closed position. In the intermediate locking position of the locked rotary latch, the closing element can then be held by the hook-shaped extension of the leg.

  • The locking device according to the invention is according to a first embodiment in the 4 to 7 presented and in their entirety with 10 designated.
  • evidenced 4 serves the locking device 10 establishing a not fully illustrated vehicle front door 11 one of the sake of clarity not shown motor vehicle. The locking device 10 is usually in the foremost area of the motor vehicle, which moves in operation, for example in the direction of travel X, arranged approximately above the vehicle bumper and fixed there on the body side. For cooperation with the locking device 10 has the vehicle front flap 11 a closing element in the form of a U-shaped striker shown in the figures in side view 12 with a horizontal striker base leg 46 on.
  • The vehicle front flap 11 is in 4 shown in its fully closed position, in which the striker 12 from a body-side, about a pivot axis 13 pivotable catch 14 is penetrated, wherein the striker base leg 46 in the mouth 47 the catch 14 is arranged. The catch 14 is in the illustrated closed position of a about a pivot axis 15 pivotable pawl 16 locked, leaving the striker 12 and thus also the vehicle front flap 11 are fixed relative to the vehicle body. The catch 14 has for this purpose a first contact surface 32 on, which for locking the catch 14 in its closed position by a locking surface 45 the pawl 16 is contactable.
  • The catch 14 and the pawl 16 are common with a lever element 17 on a body-side mounting plate 18 assembled. That around a pivot axis 19 pivotable lever element 17 is formed essentially two-armed, wherein a first lever arm 20 at its the pivot axis 19 opposite end of arm 21 a blocking area 22 to interact with the catch 14 while the second lever arm 23 including the coupling of the lever element 17 with the pawl 16 serves. For this purpose, the second lever arm 23 a coupling cam 24 on which in one, in the pawl 16 sunken, backdrop 25 intervenes. In this way, the lever element 17 and the pawl 16 formed motion coupled.
  • The second lever arm 23 also has a lever extension 26 on, which at its extension end 27 fastener 28 for connecting a cable in the form of a Bowden cable 29 provides.
  • There the soul 30 of the Bowden cable 29 with a safety anchor 31 which of the fasteners closes 28 of the lever element 17 is engaged behind, is the lever element 17 by operation of the Bowden cable 29 in the pulling direction Z about its pivot axis 19 pivoted clockwise with respect to the figures.
  • The end of the Bowden cable, not shown 29 leads into the vehicle interior and closes there with an actuating element, for example an operating handle. This operating handle can be actuated by the driver without having to leave the vehicle to do so.
  • As already stated, is in 4 the closed position of the front flap 11 indicated. The catch 14 is in its closed position in which it is from the pawl 16 is locked. The pawl 16 is of a spring element, not shown with respect to 4 along the pivoting direction A, ie clockwise biased in the illustrated locking position, while the catch 14 regarding the 4 along the pivoting direction B, ie counterclockwise, is biased by a spring element, also not shown in a release position.
  • Operates the driver from a position according to 4 the end of the Bowden cable, not shown 29 so exercises the anchor 31 (Cable nipple) of the Bowden cable 29 a force in the pulling direction Z on the lever element, which can also be referred to as a cable pull lever 17 off and pivots the cable lever 17 thereby in accordance with the figures in a clockwise direction in a position according to 5 , Due to the coupling of cable lever 17 and pawl 16 over the cam 24 becomes the pawl 16 this against their spring preload in their in 5 shown release position pivoted in which they turn the catch 14 releases.
  • Because the released catch 14 is biased in the direction of pivoting B in its release position, this then pivots out of its closed position 4 in a position according to 5 in which they are from the blocking area 22 of the cable lever 17 is prevented from further pivoting, if the pawl is still in its release position. The cable lever 17 So represents a barrier device. For completeness, it should be noted that the front door 11 in this pivoting of the catch 14 from the closed position according to 4 in the position according to 5 is slightly shifted with respect to the figures upwards.
  • 5 illustrates the essential idea of the locking device according to the invention 10 : While the pawl 16 is in its release position, blocks the blocking surface 22 of the cable lever 17 the catch 14 and prevents further pivoting of the catch 14 in Pivoting direction B. Would the blocking surface 22 the catch 14 do not prevent further pivoting, so could the catch 14 with activated Bowden cable 29 , ie in the release position located pawl 16 , simply swing it into its release position without touching the pawl 16 hold true. In other words, a sustained operation of the Bowden cable 29 by the driver to an immediate opening of the front door 11 lead without the front door 11 or the catch 14 is locked in an intermediate catch position. To avoid confusion, it should be noted at this point that the catch 14 in their position according to 5 not yet in its intermediate catch position. 5 shows a securing position in which the blocking surface 22 of the cable lever 17 with a second contact surface 33 the catch 14 to block the catch 14 interacts.
  • The actual intermediate catch position of the catch 14 is reached only after the driver, the actuator of the Bowden cable 29 let go again. Then the pawl 16 due to their preload from their release position according to 5 in their locking position according to 6 zurückverschwenken. By coupling with the pawl 16 becomes the cable lever 17 doing with respect to the figures in the counterclockwise direction according to its initial position 6 moved back. This pivoting of the cable lever 17 leads both to a return displacement of the Bowden cable 29 including securing anchor 31 in the starting position as well as that the Sperrfläche 22 of the cable lever 17 and the second contact surface 33 the catch 14 out of contact, so the catch 14 is released and due to the spring preload from its securing position according to 5 in the direction of pivot B in their intermediate locking position according to 6 pivoted.
  • The catch 14 can not swing undisturbed in their release position, since they with their second contact surface 33 now on the locking surface 45 the pawl again in its locked position 16 meets and of this in their interlocking position according to 6 is locked.
  • evidenced 6 there is the vehicle front flap 11 in a raised position. The front flap-side striker 12 is no longer from the rotary latch 14 set, but is held by this only. The re 6 left rotary latch legs 34 is designed hook-shaped and prevents with its hook extension 35 that the striker base leg 46 completely out of the rotary latch mouth 47 exit and the front door 11 can be opened further. The striker 12 is in this locked intermediate catch position of the catch 14 held, that is with respect to the 6 blocked upwards. However, this holding is only one-sided, so that a movement of the striker 12 regarding the 6 down is possible. Such a downward movement of the striker may, for. B. done when the driver has operated the Bowden cable accidentally and now the front door 11 again manually by pressure to return to their closed position.
  • Starting from the position according to 6 the driver must use the Bowden cable 29 press again to the front flap 11 , or the striker 12 completely release. By re-pressing the pawl 16 from its locked position according to 6 back to their release position according to 7 transferred so that the catch 14 is released and due to their spring bias along the pivot direction B in its release position according to 7 pivoted.
  • The striker 12 is in the release position located catch 14 evidenced 7 released, the striker base leg 46 has the mouth 47 the catch 14 leave and the front door 11 Can now be opened by the driver manually or possibly also with additional electronic or mechanical aids completely.
  • With respect to the embodiment of the 4 to 7 should finally be noted that the actuation of the lever element 17 and thus also the operation of the pawl 16 from the vehicle interior takes place. However, it is also conceivable that at the vehicle front side, so for example in the area above the vehicle bumper, additional means for actuating the lever element 17 or the pawl 16 are provided.
  • A second embodiment of the device according to the invention will now be described with reference to 8th to 12 be explained.
  • 8th schematically shows a locking device 10 ' when in the closed position rotary latch 14 ' , The cooperating with the catch striker and adjoining the striker vehicle front door are omitted for clarity. Regarding the 8th is the motor vehicle front door, not shown, analogous to 4 above the illustrated locking device, wherein the striker, not shown, of the rotary latch 14 ' is determined.
  • The catch 14 ' is about its pivot axis 13 ' pivotable and by a spring element, not shown with respect to the 8th biased in the clockwise direction to its release position. The catch 14 ' has a first contact nose 36 with a first contact surface 32 ' and a second contact nose 37 with a second contact surface 33 ' on.
  • In her in 8th shown closed position is the catch 14 ' at their first contact surface 32 ' from a locking surface 45 ' one around a pivot axis 15 ' pivotable pawl 16 ' contacted and locked in this way. The pawl 16 ' For this purpose, it is approximately V-shaped, with a first, the locking surface 45 ' having locking legs 38 and a second locking leg 39 between which a flat pawl mouth 40 is trained. In terms of 8th is the pawl 16 ' counter-clockwise biased in its illustrated locking position by a spring element, not shown.
  • In the pawl mouth 40 the pawl 16 ' grips a coupling nose 41 a markable as a cable lever lever element 17 ' a, which with respect to the figures of a spring element, not shown, clockwise about its pivot axis 19 ' in the in 8th is biased shown starting position.
  • The cable lever 17 ' is designed with three arms. He has a first lever arm 20 ' with one at one end of the arm 21 ' arranged blocking surface 22 ' for cooperation with the rotary latch 14 ' , a second, the nose 41 having lever arm 23 ' and a third lever arm 44 for attachment of a cable or Bowden cable only schematically shown in the figures 29 ' on. The other, not shown end of the cable 29 ' can be operated by a driver located inside the vehicle to open the front door, not shown.
  • When the cable is operated 29 ' in the pulling direction Z, the cable lever pivots 17 ' from the starting position according to 8th with respect to the figures counterclockwise in a position according to 9 until the cable lever 17 ' with a leading edge 42 on a guide surface 43 the catch 14 ' meets. Due to the pivoting of the cable lever 17 ' becomes the pawl 16 ' due to the coupling of coupling nose 41 and pawl mouth 40 in her in 9 shown release position pivoted. This pivoting of the pawl 16 ' takes place against the spring biasing force, with respect to the figures in a clockwise direction. The locking surface 45 ' the pawl 16 ' This causes out of contact with the first contact nose 36 or the first contact surface 32 ' the catch 14 ' so that the catch 14 ' is released.
  • The released catch 14 ' can now pivot clockwise due to its spring bias with respect to the figures until it, as in 10 represented, with the second contact surface 33 ' Your second contact nose 37 on the blocking area 22 ' of the cable lever 17 ' meets. The catch 14 ' is in this safety position of the cable lever 17 ' prevented from further pivoting. In the 10 illustrated securing position of the catch 14 ' corresponds analogously to the position of the rotary latch 14 according to 5 of the first embodiment.
  • If the catch 14 ' in their secured position according to 10 from the cable lever 17 ' is locked and the driver the operation of the cable 29 ' can break off the cable lever 17 ' due to its spring bias with respect to the figures pivot clockwise, so that the cable lever 17 ' from a position according to 10 according to its original position 11 can swing back. Here are the cable lever 17 ' the second contact nose 37 and thus the entire catch 14 ' free, which then turn clockwise into its latched position according to 11 can pivot. Because the pawl 16 ' by the coupling with the cable lever 17 ' automatically pivoted back into its locked position, the catch is 14 ' evidenced 11 in its intermediate catch position of the pawl 16 ' locked. The striker, not shown, is in this case of the hook extension 35 ' of the thigh 34 ' the catch 14 ' held.
  • By pressing the cable again 29 ' in the pulling direction Z, the driver can the pawl 16 ' via a pivoting of the cable lever 17 ' in his in 12 transfer illustrated release position, causing the catch 14 ' released and transferred to its release position.
  • The vehicle operator can use the front door, not shown, starting from a position of the locking device 10 ' according to 12 either fully open or easily by pressurizing in the starting position according to 8th back transfer.
  • It should finally be noted with respect to the second embodiment that the locking device 10 ' their in 10 shown securing position basically only assumes, if the cable 29 ' is kept pressed for a long period of time. Will the cable pull 29 ' On the other hand, it is only activated very briefly, depending on the reaction time of the cable lever 17 ' assume that the in 10 shown safety position is not reached, but the cable lever 17 ' before in its starting position according to 8th swung back and the second contact surface 33 ' the catch 14 ' thus not at all on the Sperrfläche 22 ' of the cable lever 17 ' meets. However, this is safety-harmless, since the pawl 16 ' by the coupling of pawl 16 ' and cable lever 17 ' always in its locking position when the cable lever 17 ' in its initial position according to 8th located. In other words, it is ensured in the locking device according to the invention that the catch 14 ' upon reaching its intermediate catch position according to 11 always from the pawl 16 ' lockable. In its locked securing position according to 10 becomes the catch 14 however, only locked when the driver the cable 29 ' operated over a long period of time, or if he operated the cable only once, but the locking device 10 ' has a correspondingly large inertia, so if the pawl 16 ' remains in its release position for a long period of time.
