Description

The invention relates to a door lock for a vehicle, in particular for a motor vehicle, with a lock latch for locking the door through at least one door opener arranged inside the vehicle and through a door opener on the outside of the vehicle to unlock the door is adjustable, with a locking device by a closing cylinder nut and by an electrical actuator between an unlocked position in which the lock latch with the door openers is coupled, a simple locking position in which the lock latch of the door opener on the outside of the vehicle is decoupled, and one Double locking position is adjustable, in which the lock latch probably from the inside of the vehicle as well as from the outside of the vehicle provided the door opener is decoupled.

In the case of a door lock of the type mentioned at the beginning, the lock latch can be used which locks the door, unlocks the door openers. To a To prevent unauthorized persons from opening the door, the ver Locking device provided with which the lock latch for securing the Door lock in a single locking position from the outside on Vehicle and in a double locking position also from be decoupled from the door opener located inside the vehicle can. To adjust the locking device is usually one Locking cylinder nut provided with one on the outside of the door NEN lock cylinder is operatively connected, and an electrical actuator  intended. The door lock is designed so that an adjustment of the locking device from the simple locking position in the double locking position only by the electri cal actuator is possible. So that the door even with one Failure of the electrical actuating device can be unlocked, it must be ensured that the locking device from the outside through the lock cylinder both from the single locking position tion as well as from the double locking position to the entries position can be moved. The locking cylinder nut stands for this usually by several coupled levers with the Ver locking device in operative connection.

It is an object of the invention to provide a door lock in which the Coupling of the lock cylinder with the locking device comparatively simple way.

The invention solves the problem by a door lock with the features according to claim 1 and in particular by a with the lock cylinder nut active control element that is used to adjust the locking mechanism gelungseinrichtung is coupled with this, by pressing the Lock cylinder nut in a first direction the locking device ver from the unlocking position to the simple locking position is adjustable, and by pressing the lock cylinder in one the first direction opposite the second direction the locking establishment of one of the two locking positions in the entries position is adjustable.  

In the door lock according to the invention the lock cylinder nut is through a single control element coupled to the locking device. By using only a single control element with which the Locking device can be unlocked or locked, is the Assembly of the door lock according to the invention compared to known Door locks simplified, in which the lock cylinder by meh rere coupled lever with the locking device ver is bound. So with the known door locks, the levers in front given order in the housing of the door lock and be connected to each other. In contrast, the inventor must In accordance with the door lock only the adjusting lever is inserted into the door lock housing be set. Furthermore, the use of only one position a jamming of the door lock, as is the case with each other coupled levers known door locks occurs more often, almost out closed, thereby the operational safety of the door according to the invention lock is increased compared to the known door locks.

Further advantageous developments of the invention result from the following description, the drawing and the subclaims.

So is preferred in a preferred embodiment of the door lock beat the actuator with the electrical actuator tion to couple, so that when you press the lock cylinder in the first direction also the electrical actuator the latches tion device from the unlocked position to the simple locks position adjusted. Simultaneously with the electrical actuation direction, the locking device is also torn by the actuator In this way it is possible to use additional levers that hold the lock cylinders  couple with the electrical actuator, who does not the, whereby the structure of the door lock despite the additional functi on the cylinder lock is simple.

In a further development of this embodiment of the door lock further proposed that the actuator even when loading again actuate the lock cylinder in the first direction, the electrical actuation Activation device that the locking device of their Single locking position in its double locking position poses. The locking device is in this operating position in the it is in the simple locking position, but not from Actuator actuated.

Furthermore, it is advantageous if the control element with the elec trical actuator interacts that when actuated the lock cylinder in the second direction the electrical actuation device the locking device of one of the two locks in the unlocked position. This one too Embodiment of the door lock can by using the Stell element to activate the electrical actuator on additional components in the door lock can be dispensed with.

To actuate the electrical actuation device by the actuator element is proposed near the lock cylinder a first Provide microswitch, the one provided on the actuator Button is actuated. In a further development of this execution form is preferably a second Mi near the lock cylinder kroschalter provided, which also with the electrical actuator  connected is. If the cylinder lock is in the first Rich adjustment, the control element actuates the first microswitch that is on the other hand controls the electrical actuating device in such a way that it the locking device from the unlocked position to the simple Locked position or, if necessary, also in the double locks position adjusted. In contrast, the lock cylinder is in the second Moving direction, the button of the control element actuates the second one Microswitch, which in turn is the electrical actuator controls that the locking device of one of the two Ver locking positions moved to the unlocking position. By ver use of an actuator on which one for actuating the micro switch provided button is formed, can comparatively se simple way on the actuator from the lock cylinder the motion transmitted to the electrical actuator gen be forwarded.

In a preferred embodiment of the door lock, the elek tric actuator a total of two electrical actuation units for adjusting the locking device. The first electrical actuation unit is used to lock and unlock the locks device between the unlocked position and the single Locking position. The second electrical actuator serves there against for adjusting the locking device between the single Locking position and the double locking position. Here too is the actuator with the first and second electrical actuators tion unit coupled, whereby the assembly effort is low. Of further is the separate control of the locking device tion achieved by the separate electrical actuators that  in this embodiment compared to an embodiment in which only one electrical actuator for adjusting the locking device between the unlocked position, the simple locking position and the double locking position is used at same number of locking operations the separate actuation units are actuated less frequently than just an electrical actuator supply unit and the separate actuation units consequently a ver equally have a longer service life.

As a control element is preferably displaceable in its longitudinal direction cher lever used, the teeth at one end has, which with a provided on the lock cylinder Gegenver toothing is engaged. By using the control lever as a control element can the actuating movement of the lock cylinder in the ratio nis large distances to the size of the door lock, so that the locking device with a comparatively large distance to Lock cylinder nut can be arranged. This simplifies the construction of the door lock, since the individual components of the Door lock at most with little regard to the position of the Locking device can be arranged in the door lock housing nen.

Is the actuator used to operate the microswitch, such as It was particularly beneficial to use the button in training in the immediate vicinity of the toothing on the actuating lever so that the Forces generated by the gearing when switching the microswitches can be included.  

The locking device preferably has two pivotable gela raised lever, with one lever serving as a locking lever, the between a decoupling position, in which he removes the latch from the Door openers decoupled, and a coupling position is movable in the he couples the lock latch with the door openers. The as a carrier lever trained second lever is used to adjust the locking lever between its decoupling position and its coupling position. The In this embodiment, the adjusting lever has an elongated hole, which with the driver lever is in operative connection and when actuated the locking cylinder nut comes into engagement with the driver lever in this way, that the driver lever is pivoted and the locking lever of its decoupling position to its coupling position or vice versa emotional.

The driver lever is in a preferred embodiment by a elastic element, preferably a compression spring, with the locks tion lever coupled such that the driver lever relative to the Verrie lever is pivotable when the locking lever is blocked, and that the driver lever the locking lever between its Decoupling position and its coupling position adjusted when the Locking lever is not blocked. This way you can total three different switching states of the locking device on simp che way can be realized.

In a further development of this embodiment it is proposed the locking lever in its position in which it actuates the keeps decoupled from the lock latch, in addition to block so despite an actuating movement of the driving lever, the locking lever  remains in its decoupling position. However, is the interlocking bel released, he can from his decoupling position in his Kopp position can be adjusted. In this way, the locks The simple locking system in an elegant and simple way and double locking with a single locking lever make.

In this embodiment of the door lock, in which the aforementioned Locking device is used, the electrical actuator supply device preferably two electrical actuation units, the electrical actuation units be independent of each other are driven and to adjust one of the two levers of the Ver locking device serve.

The invention will be described below using an exemplary embodiment ter explained in more detail with reference to the accompanying drawings. In it gene:

Fig. 1 is a plan view of an inventive door lock is in ner dual-locking position,

Fig. 2 is a plan view of the door lock of FIG. 1 during the adjustment in its double locking position, and

Fig. 3 is a plan view of the door lock of FIG. 1 while understanding in its unlocked position.

Fig. 1 shows a top view of a door lock 10 for a motor vehicle. The door lock 10 usually has a lock latch (not shown) with which the door of the motor vehicle can be locked on the door frame. With the help of a door opener arranged inside the vehicle and a door opener provided on the outside of the vehicle door, the lock latch of the door lock 10 can be unlocked so that the door can be opened. In order to prevent opening of the vehicle door by unauthorized persons, the door lock 10 is equipped with a locking device 14 arranged in the door lock housing 12 , with which the door opener for securing the door lock 10 can be decoupled from the lock latch, as will be explained later.

To operate the locking device 14 is in the door lock housing 12 with a lock cylinder not shown in operative connection lock cylinder 16 is accommodated, which is arranged in the figures in the upper section of the door lock housing 12 and can be actuated from the outside when the door lock 10 is mounted. The locking cylinder nut 16 is coupled by a control lever 18 with the locking device 14 shown in FIGS. 1 to 3 in the lower region of the door lock housing 12 ge. Between the locking device 14 and the lock cylinder nut 16 , two electrical actuation units 20 and 22 in the door lock housing 12 are added, which also serve to secure and unlock the locking device 14 .

The locking device 14 has two levers 26 and 28 which are pivotably mounted on a common first bearing journal 24 . The guren in the Fi partially obscured drawn lower drive lever 26 has a protruding in the figures to the right-facing first tab 30 from the vertically upward parallel to the longitudinal direction of the first pivot pin 24 is a Actuate the supply tap 32nd By about 90 degrees offset from the first lug 30 viewed in the counterclockwise direction of the figures, protrudes from the contractor with lever 26 from a second lug 34, also protruding from the vertically upward a driver pin 36th The driver lever 26 is used to operate the upper locking lever 28 , as will be explained later tert.

The upper locking lever 28 , which is used to decouple the lock latch from the door openers and which is pivotably mounted on the lower driving lever 26 on the first bearing pin 24 , has a radially outwardly protruding actuating section 38 which is angled at its end and points to the right in the figures . The two levers 26 and 28 are elastically coupled to one another by a compression spring 39 such that the two levers 26 and 28 can be pivoted relative to one another, but return to their rest position by the compression spring 39 , as shown in the figures , as soon as external forces on the two levers 26 and 28 are eliminated.

The locking lever 28 is movable between a coupling position, in which it brings the two door openers into operative connection with the lock latch, and a decoupling position, in which it decouples the two door openers from the lock latch. To adjust the locking lever 28 is the driver lever 26 , which, coupled by the compression spring 39 , the locking lever 28 between the coupling position and the decoupling position can pivot back and forth. The INTERLOCKS is lung lever 28 in its coupling position, the Verriegelungseinrich tung is moved to its unlocked position fourteenth On the other hand, the locking lever 28 is in its decoupling position, the locking device 14 is at least simply locked. For double locking the locking device 14 , the locking lever 28 can also be blocked in its decoupling position, as will be explained in detail later, so that despite a movement of the driver lever 26, the locking lever 28 remains in its decoupling position, the between the two levers 26 and 28 arranged compression spring 39 is stretched accordingly and pulls the driving lever 26 back into its starting position after its actuation.

The locking device 14 is thus between an unlocking position in which the lock latch is coupled to the door openers, a single locking position in which the lock latch is decoupled from the door opener arranged on the outside of the vehicle, and a double locking position in which the The lock latch is decoupled both from the door opener provided inside the vehicle and from the outside of the vehicle. The latter double locking position serves, inter alia, to ensure that unauthorized persons who, for example, break in the window of the vehicle, cannot operate the door lock 10 from inside the vehicle.

For operating the drive lever 26 is manually housing on Türschloßge 12, an unillustrated intermediate lever of a door knob mounted pivotably engaged with the operating pin 32 of the driver lever 26 in operative connection. The intermediate lever is in turn coupled to the inner door opener. Is the locking device 14 in its unlocked position, in which the door knob is in its raised position, the door lock 10 can be operated by both in the neren and by the outer door opener.

To simply lock the locking device 14 from the vehicle interior, only the door button has to be pressed down. The door knob operated by the intermediate lever and the actuating pin 32, the driver lever 26 , which in turn pivots the locking lever 28 into its decoupling position.

If the locking lever 28 is not blocked in its decoupling position, the door lock can be opened either by pulling the door knob or by pressing the inner door opener. When the door button is actuated, the driver lever 26 is pivoted by the intermediate lever, which in turn adjusts the locking lever 28 from its decoupling position to its coupling position by means of the compression spring 39 , in which it couples the door opener to the lock latch. If, on the other hand, the door opener inside the vehicle is actuated, it first presses the door button into its raised position. During its movement into the raised position, the door knob in turn adjusts the driving lever 26 through the intermediate lever, which pivots the locking lever 28 into the coupling position through the compression spring 39 .

If, on the other hand, the locking lever 28 is blocked in its decoupling position, the locking lever 28 remains despite the movement of the slave lever 26 by the compressibility of the compression spring 39 in its uncoupling position, so that the door lock 10 remains locked even when the door knob is pulled or the inner door opener is actuated .

For electrical actuation of the locking device 14 , two electrical actuation units 20 and 22 are arranged in the door lock housing 12 . The first electrical actuation unit 20 shown on the left in the figures serves to adjust the locking device 14 between the unlocked position and the simple locking position. For this purpose, the first electrical actuation unit 20 has a first electrical drive 40 which is operatively connected by a first gear arrangement 42 to a threaded spindle 44 . Along the first Ge threaded spindle 44 , a first spindle nut 45 can be moved as soon as the first threaded spindle 44 is rotated about its longitudinal axis. The first spindle nut 45 is connected by a protruding pin 46 with a pivotable about a second journal 47 adjusting plate 48 so that when the first spindle nut 45 moves along the first threaded spindle 44, the adjusting plate 48 is pivoted about the second journal 47 . For coupling the first spindle nut 45 with the actuator plate 48 has a teardrop-shaped opening in about 49 is formed on the actuator plate 48, in which the pin protrudes 46th The peripheral edge of the opening 49 is shaped such that the pin 46 touches the peripheral edge during the linear movement of the first spindle nut 45 so that the force transmitted from the pin 46 to the setting plate 48 acts in the longitudinal direction of the threaded spindle 44 .

On the setting plate 48 , a recess 50 is formed, in which the slave pin 36 protrudes. The recess 50 is designed so that it can adjust the driver pin 36 and thus the driver lever 26 . The length of the recess 50 is dimensioned such that the entraining pin 36 can be adjusted relative to the recess 50 when the steep plate 48 is in its neutral position shown in the figures, in which the first spindle nut 45 is approximately in the middle between the ends of the first threaded spindle 44 is positioned.

If the first electrical actuation unit 20 is now activated, the first electrical drive 40 drives the first threaded spindle 44 , as a result of which the steep plate 48 is pivoted and the drive pin 36 projecting into the recess 50 is carried along. As a result, the catch lever 26 adjusts the locking lever 28 either from the coupling position to the decoupling position or vice versa, depending on the direction in which the threaded spindle 44 rotates.

The second electrical actuation unit 22 arranged to the right of the first electrical actuation unit 20 in the figures has a second electrical drive 52 , which is likewise coupled to a second threaded spindle 56 by a gear arrangement 54 . The second threaded spindle 56 runs at least approximately parallel to the longitudinal direction of the actuating lever 18 . On the second threaded spindle 56 , a spindle nut 58 is screwed, which can be adjusted by rotating the second Ge threaded spindle 56 along this. The spindle nut 58 is rounded at its end facing the second drive 52 . Furthermore, an adjusting pin 59 protrudes vertically upward from its upper side, the purpose of which will be explained later.

If the spindle nut 58 is moved along the second threaded spindle 56 into its lowered position, in which it is arranged at a short distance from the locking device 14 (see FIG. 3), the rounded end face of the spindle nut 58 is cut out of contact with the Stellab 38 of the locking lever 28 . Consequently, the locking lever 28 can be moved back and forth by the driver lever 26 between its coupling position and its decoupling position.

If the spindle nut 58 in the direction of the second drive 52 ent along the second threaded spindle 56 by the rotation of the second Ge threaded spindle 56 is moved into its raised position, the spindle nut 58 presses with its rounded end face the actuating section 38 of the upper locking lever 28 , thereby the upper locking lever 28 is pivoted counterclockwise from its coupling position into its decoupling position. Since the spindle nut 58 abutting the actuating section 38 prevents a pivoting movement of the locking lever 28 , ie blocks it, despite an actuating movement of the driving lever 26 , the locking lever 28 cannot be moved into its coupling position. In this way the locking device 14 is adjusted in its double locking position.

The actuating lever 18 has at its near the lock cylinder nut 16 arranged upper end a toothing 60 which engages with a trained on the lock cylinder nut 16 , correspondingly designed Gegenver toothing (not shown). The toothing 60 is made of plastic and is injected onto the adjusting lever 18 made of metal. A button 62 is also formed on the toothing 60 and faces the locking cylinder nut 16 . On both sides of the lock cylinder 16 , two microswitches 64 and 66 are provided, which are arranged along a common line in such a way that when the actuating lever 18 moves in the longitudinal direction thereof, the button 62 , depending on the direction of movement of the actuating lever 18, the upper microswitch 64 or the actuated lower microswitch 66 . The two microswitches 64 and 66 are connected by a control unit, not shown, to the drives 40 and 52 of the two electrical actuating units 20 and 22 .

The adjusting lever 18 has a narrow section 68 adjoining the toothing 60 , to which a wider section 70 adjoins. At the transition from the narrow section 68 into the wide section 70 , a driver hook 72 protrudes at right angles from the actuating lever 18 in the direction of the second threaded spindle 56 of the second electrical actuating unit 22 . The slightly rounded driver hook 72 on its top facing the second drive 52 can be brought into engagement with the adjusting pin 59 of the spindle nut 58 of the second electrical actuation unit 22 and adjust the spindle nut 58 along the second threaded spindle 56 , as will be explained later.

In the wider portion 70 of the actuating lever 18 is formed in the longitudinal direction extending slot 74 which is open on the Verriege treatment device 14 side facing. In the slot 74 protrudes the first nose 30 of the lower locking lever 26 , so that the vertical right from the first nose 30 protruding actuating pin 32 is arranged in the slot 74 . The slot 74 is dimensioned and formed on the actuating lever 18 that when the actuating lever 18 is in its rest position shown in Fig. 1, the peripheral edges of the elongated hole 74 are out of engagement with the actuating pin 32 , and the lower locking lever Ver 26 adjustable is without the actuating pin 32 comes into contact with the edge of the elongated hole 74 .

The function of the door lock 10 is explained in more detail below with reference to FIGS . 1 to 3.

If the door lock 10 is unlocked, the locking device 14 is in its unlocked position, in which the lock latch is coupled to the door openers of the door. As soon as the locking cylinder nut 16 is actuated counterclockwise in the closing direction (see FIGS. 1 to 3), the adjusting lever 18 is adjusted in its longitudinal direction in the direction of the upper microswitch 64 by the toothing 60 which engages with the counter-toothing of the locking cylinder nut 16 , the button 62 actuates the upper microswitch 64 , as shown in FIG. 2. As soon as the upper microswitch 64 is actuated, the first electrical drive 40 of the first electrical actuation unit 20 is activated, which drives the first threaded spindle 44 in such a way that the steep plate 48 is rotated clockwise and takes the driving pin 36 with it. By this actuating movement of the driver lever 26 is adjusted, which in turn takes the locking lever 28 and adjusts it in its decoupling position, in which the lock latch is decoupled from the door openers, whereby the locking device 14 is in its simple locking position. Then the setting plate 48 returns to its neutral position shown in FIGS. 1 to 3.

If the upper microswitch 64 or the first electric drive 40 should have failed due to a technical defect, the locking cylinder 16 of the driving lever 26 is adjusted by the actuating lever 18 during actuation by the elongated hole 74 with its edge on the actuating pin 32 engaging and so the driving lever 26 pivots counterclockwise. The driver lever 26 then in turn moves the locking lever 28 into its decoupling position, in which the door openers are decoupled from the lock latch.

If the door lock 10 is now to be secured twice, ie that the locking device 14 is placed in its double locking position, the cylinder nut 16 must be moved back to its neutral position and rotated again into the locking position, whereby the above microswitch 64 is actuated again . If the locking device 14 is already in its single locking position, the control unit (not shown) activates the second electric drive 52 of the second electric actuation unit 22 . As soon as the second electric drive 52 has been activated, the second threaded spindle 56 rotates and moves the spindle nut 58 into its raised position, the spindle nut 58 with its rounded end face having the section 38 of the lever 28 pivoted into the coupling position and coming into contact and blocked it. In this manner, the locking device is chert 14 in its two-compartment locking position gesi, moves along in the on actuation of the drive lever 26 of the Mitneh merhebel 26 free to displace without the lock lever 28 but only compressed, the compression spring 39, which in turn merhebel the Mitneh 26 moved back to its starting position after its actuation. This operating position, in which the door lock 10 is secured twice, is shown in Fig. 1.

In an alternative embodiment of the control unit, it is proposed that the locking cylinder 16 only have to be held in its locking position for a predetermined period of time for adjusting the locking device 14 in its double locking position, so that the actuating lever 18 actuates the upper microswitch 64 over a longer period of time , which is detected by the control unit and evaluated as a double locking signal. The control unit then sequentially activates the first electrical actuator 20 and then the second electrical actuator 22 to lock the locking device 14 in the manner previously described. Furthermore, there is also the possibility of adjusting the locking lever 28 only by the second electrical actuation unit 22 , with the slave lever 26 being carried along by the compression spring 39 . Regardless of this, there is also the possibility of additionally operating the two electrical actuation units 20 and 22 by a remote control, not shown.

If the door lock 10 is now to be unlocked, the locking cylinder nut 16 is turned clockwise into its unlocking position. The rotary movement of the locking cylinder nut 16 moves the adjusting lever 18 downward in its longitudinal direction, its button 62 coming into contact with the lower microswitch 66 (cf. FIG. 3). By actuating the lower microswitch 66 , the two electrical actuation units 20 and 22 are activated, the spindle nut 58 being moved into its lowered position so that the locking lever 28 is no longer blocked. At the same time, the first electric drive 40 is activated such that the adjusting plate 48 adjusts the driver lever 26 , which in turn moves the locking lever 28 into its coupling position, in which the lock latch is coupled to the door openers.

If at least one of the two electrical actuation units 20 and 22 has failed due to a malfunction, for example due to a malfunction of the lower microswitch 66 or a malfunction of one of the two drives 40 and 52 , the door lock 10 is unlocked by the actuating lever 18 , as explained below becomes. In the double-locked state, the door lock 10 is in the functional state shown in FIG. 1. In this state, the locking lever 28 is pivoted counterclockwise into its decoupling position, in which the lock latch is decoupled from the door openers, and is blocked by the spindle 58 adjusted in the direction of the second drive 52 in its decoupling position. The driver lever 26 in turn is adjusted counterclockwise by the locking lever 28 so that its actuating pin 32 is arranged approximately centrally between the ends of the elongated hole 74 of the actuating lever 18 .

If the locking cylinder nut 16 now rotates into its unlocking position, it adjusts the actuating lever 18 in the direction of the lower microswitch 66 . Should, as already mentioned, unlocking the locking device 14 by the electrical actuation units 20 and 22 no longer be possible, the driver hook 72 first comes into engagement with the adjusting pin 59 of the spindle nut 58 and pulls the spindle nut 58 into its lowered position, whereby the second threaded spindle 56 is rotated accordingly. The spindle nut 58 is pulled out of engagement with the actuating section 38 of the locking lever 28 so that it is no longer blocked, but can be moved freely clockwise from its decoupling position to its coupling position. Approximately at the same time the upper portion of the circumferential edge of the elongated hole 74 comes into engagement with the actuating pin 32 of the slave lever 26 and pivots it clockwise. Due to the pivoting movement of the driver lever 26 , the locking lever 28 is pivoted by the compression spring 39 into its coupling position, in which it couples the lock latch with the door openers. He enables the moving in its neutral position plate 48 due to the dimensions of its recess 50 a movement of the Mitnehmerzap fens 36 relative to the plate 48th As soon as the locking cylinder nut 16 returns to its neutral position, the actuating lever 18 is again moved into its neutral position shown in FIG. 1.

If the door lock 10 is simply secured, ie that the locking device 14 is in its simple locking position, the locking lever 18 is moved in the unlocking position of the actuating lever 18 in the direction of the lower microswitch 66 when the locking cylinder 16 is rotated. In this case, if an actuating movement by the first electrical actuation unit 20 is not possible, the door lock 10 is only opened by the actuating lever 18 . As soon as the actuating lever 18 is pressed in the direction of the lower microswitch 66 , the driver hook 72 is guided past the actuating section 38 of the upper locking lever 28 , while the upper circumferential edge of the elongated hole 74 comes into engagement with the actuating pin 32 of the driver lever 26 , which in turn engages the locking lever 28 pivots into its coupling position in which the lock latch is coupled to the door openers. After opening the door lock 10 , the lock nut 16 is rotated back into its neutral position and the actuating lever 18 is raised again, the lever 26 not being adjusted by the dimensions of the elongated hole 74 , but remains in its neutral position ver.
