Description

The invention relates to a locking device for a vehicle according to the preamble of Claim 1 or claim 2.

Such a closing device comprises at least one lock; one the lock states the locking device (i.e., the lock states of the lock or locks) Transmission, by which the closing device in at least three or four different lock states can be brought, for example, the unlocked, the locked, the theft-proof and the child-safe state correspond; and a rotatably mounted contour disc of the transmission, which defines the Lock state is rotatable with a drive, the different lock states each certain angular positions of the contour disc are assigned.

In one known from DE 199 17 789 A1 locking device of this type is the Contour disc through a drive disc provided with inner and outer elevations formed, which is scanned by one end of a lever. The other end of the lever is the lock (that is, the locking parts of the locking device, such as a rotary latch and a pawl) and affects the interaction of an actuator, such as. a door handle or outside door handle, with the lock. For example, in the theft-proof state of the closing device is the Lock operated neither by means of the inside door handle nor by means of the outside door handle.

That is, an operation of the inside door handle or the outside door handle is not on the corresponding lock elements (e.g., pawl and catch) are transmitted. Conversely, the door can be both in the unlocked state of the locking device open by means of the inside door handle as well as by means of the outside door handle. In appropriate In this way further lock states, such as e.g. the locked or the child-secured Define state.

The invention is based on the problem of a closing device of the input mentioned type to further improve, especially in terms of ease of use.

This problem is inventively with the creation of a locking device the features of claim 1 or of claim 2 solved.

According to claim 1 is in a contour disc with which the closing device in at least four different lock states can be brought, the contour disc designed such that the contour disc from each angular position, the one unlocked from the different Condition (e.g., locked condition, theft or parental control), immediately in an unlocked state corresponding angular position can be brought without Here, a third lock state occurs.

The solution according to the invention may, in a specific embodiment, be e.g. thereby be realized that the individual lock states each determined Angle areas are assigned to the contour disc, wherein the angle ranges in Circumferential direction of the contour disc are arranged one behind the other and at each Angle range of contour disc, one of unlocked different state is assigned immediately adjoins an angular range, the unlocked State is assigned.

In the solution according to the invention therefore not just the individual Lock states arranged one behind the other on the contour disc, but to each Angular range corresponding to a state different from the unlocked state, At least one angular range, which corresponds to the unlocked state, is adjacent. For this must be provided on the contour disc multiple angle ranges, each correspond to the unlocked state.

The solution according to the invention has the advantage that of each lock state of the Unlocked state is different, a very fast transition to the unlocked state is possible. The solution according to the invention is particularly useful advantageous to apply so-called keyless-entry or passive-entry systems which the locking device is automatically transferred to the unlocked state, when a person approaches the vehicle and presses its exterior door handle, the from the system has been identified as a person authorized to drive the vehicle is. The authorized person can be identified, for example, by means of a signal generator they carry with them.

In such locking systems, it is necessary that after identification of the Use authorized person and by pressing the outside door handle by a such person brought the locking device very quickly in the unlocked state becomes. Otherwise the door would not open immediately when the outside door handle is actuated, which interpreted by the user as a defect or at least as uncomfortable would be felt. Problems of this kind can occur especially when the Locking device is in a lock state, which still by other lock states is disconnected from the unlocked state. The solution to these problems desirable rapid transition to the unlocked state is achieved by the invention Solution guaranteed.

The inventively designed locking device can be used both in locking systems with only one lock (e.g., single vehicle door closure) as well Locking systems for actuating several locks (central locking in Motor vehicles) are used.

According to claim 2, in a closing device with a gear, with which the Locking device can be brought into at least three different lock states, the Contour disc designed such that upon rotation of the contour disc along a predetermined direction of rotation to a different unlocked from the state always immediately follows the unlocked state. In other words, there is at least one direction of rotation with the property that upon rotation of the contour disc along this Direction of rotation on each area of the contour disc with one different from the unlocked one Condition each corresponding to the unlocked state area follows.

In this case, not only is it guaranteed that everyone from the unlocked state various state on the contour disc is adjacent to an area of the unlocked State corresponds, but it is moreover even guaranteed that at a rotation of the contour disc along a certain direction of rotation in each case the immediate Transition to the unlocked state is possible.

The inventively designed contour disc can be easily by a disc-shaped body are formed, which extends in a plane and in particular can be integrally formed. Thus, the contour disc by a Cam are formed, in which the outer and / or inner contour of the represent different lock states.

The unlocked state of the closure device preferably corresponds to one Lock state in which each lock is unlocked. There is only one, clearly defined, unlocked lock state, namely the state of the locking device, in which all locks are unlocked so that the corresponding flaps of the Vehicle (e.g., vehicle doors in the case of door locks) without children or Anti-theft device can be opened.

The contour disc interacts with a coupling element which forms the contour disc scans and depending on the angular position of the contour disc an actuator (ie, for example, an outside door handle or a door inside handle) with the Lock couples or decoupled from the lock. Only with a coupling of the respective Actuator with the lock this can be operated to open the door.

By using two coupling elements that scan the contour disc and the depending on the angular position of the contour disc one each Actuator with the lock couple or decouple from this, can lock states defined by a contour disc to two different Actuating devices (in particular a door outer door and a door inner opener) be transmitted.

For this purpose, on the one hand on the contour disc two radially spaced from each other Contours can be provided, each with one of the two coupling elements interact. On the other hand, the two coupling elements on the same contour the contour disc scan, in which case the two coupling elements along the Circumferential direction of the contour disc are arranged spaced from each other.

The contour disc itself is rotatable by means of a drive, which by pressing a Lock cylinder of the lock, a remote control (e.g., via a passive entry system) or another closing element can be put into operation.

Further features and advantages of the invention will become apparent in the following Description of embodiments will be apparent from the figures.

A schematic representation of a door lock and the associated holder in Figures 5a and 5b shows the locking parts of the door lock, namely one to a Axis 30 pivotable pawl 3 with a hook 31 and one with the Pawl 3 cooperating, pivotable about an axis 20 rotary latch 2 with a recess 21 which is associated with a locking pin 80 of the holder 8. Further a sensor 25 is provided, with which the outer contour of the catch 2 to Determination of the angle of rotation is scanned. The castle forming locking parts 2.3 (Rotary latch and pawl) are arranged in a lock housing 90, which on a Door panel is attached.

A locking device of the type described above is well known and therefore need not be explained in more detail.

Of importance for the present invention is the design of a contour disc, can be fixed by means of the different lock states of the locking device. The Essential lock states are the unlocked state, the locked Condition, the lock state "child-proof" and the lock state "Antitheft". Under the unlocked state is the one lock state understood in which the lock both by means of the inside door handle and by means of the outside door handle can be operated to open the door. In the locked state In contrast, the outside door handle is decoupled from the lock, so that the door is not can be opened by pressing the door outer handle. Conversely, in lock state "child resistant" the door inner handle of the lock decoupled, so that the door is not can be opened by pressing the inside door handle. In the lock state "theft-proofed" Finally, both the inside door handle and the outside door handle of the door lock are decoupled so that this neither by means of the inside door handle nor by means of the outside door handle to operate to open the door.

In a locking device to control multiple locks are in the lock state "child-resistant" often only the rear doors of a motor vehicle accordingly secured while the front doors are in the unlocked state. Yet The child-resistant state of the locking device clearly differs from the unlocked state, with respect to the state of the locks of rear doors.

In Figure 1a, a contour disc 1 is shown schematically, with the above have specified enumerated lock states. The contour disc 1 consists of a about a axis A rotatably mounted disc-shaped base body 10, by means of a drive M is rotatable. The drive M, for example, by an operation of the lock cylinder or by means of a remote control to be triggered by Rotation of the contour disc 1 to change the current lock state.

The contour disc 1 is along its circumference in 6 identical sections or Angle ranges 16, 16 ', 16 ", 17, 18 and 19, which along the periphery 15 of the disk-shaped base body 10 are arranged one behind the other and each one Sweep angle range of 60 °.

Of the mentioned sections, three sections 16, 16 ', 16 "are the unlocked state E, a portion 17 of the locked state V, a portion 18 of the lock state "theft-proofed" S and a further section 19 of the castle state "child-proofed" K. The individual lock states E, V, S, K assigned Sections or angular ranges 16 to 19 of the contour disc 1 are in this case arranged one behind the other, that upon rotation of the contour disc 1 about its axis A along a direction D (clockwise) to one of the unlocked state E different lock states K, S, V immediately followed by the unlocked state E. This also applies to a rotation of the contour disc 1 in the opposite direction, ie counterclockwise.

It is clear from FIG. 1a that a state corresponding to the unlocked state E is shown Section or angle range (16 ") could be omitted and that too each of the sections or angular areas 17 to 19, one of the unlocked state E different lock state V, S or K represent, a section or angle range 16, 16 'would be adjacent, which corresponds to the unlocked state E. In In this case, the immediate transition from lock state V ("locked") would be or from lock state K ("child-proofed") to lock state E ("unlocked") no longer possible with any direction of rotation of the contour disc 1. The direct Transition from the lock state K ("child-proofed") to the lock state E ("unlocked") Rather, it would only be in a clockwise rotation of the contour disc 1 and the immediate transition from the lock state V ("locked") in the lock state E ("unlocked") only with a rotation of the contour disc counterclockwise possible.

Only if a total of three sections or angular ranges 16, 16 ', 16 "of the contour disc represent the unlocked state E is ensured that during a rotational movement along exactly one direction of rotation D to each lock state V, S, K, of the unlocked state E is different, each immediately the unlocked state E follows.

FIG. 1b shows an exemplary embodiment of a specific embodiment of the device shown in FIG. 1a shown schematic contour disc 1. The contour disc shown in Figure 1b 1 has in its disk-shaped base body 10 two radially from each other spaced, in the circumferential direction 15 of the contour disc 1 extending contours 11, 12th on. The contours 11, 12 are each formed by a circumferential guideway 11a and 12a, which are provided with radially projecting elevations 11b, 12b. The Bumps 11 b, 12 b are each in the circumferential direction of the corresponding Kon-tur 11, 12 spaced apart and form part of the corresponding Contour 11 or 12.

The two contours 11, 12 of the contour disc 1 are each by a coupling element sampled, as will be explained below with reference to Figures 2a and 2b.

A coupling element, which is guided in one of the contours 11, 12, is then in each case moved radially outward, if at a rotation of the contour disc 1 to its axis A one of the elevations 11 b, 12 b of the corresponding coupling element is felt. In the present case, it is assumed that the sampling of the outer contour 11 by means of a coupling element of the door inner handle of the locking device coupled to the lock or decoupled from this, while by Scanning the inner contour 12 by means of another coupling element of the outside door handle is decoupled from the door lock and coupled with this. It should be a Coupling between the corresponding control device (outside door handle or inside door handle) each with the door lock, if the associated Coupling element a survey 11 b, 12b ertastet.

In this case, the unlocked state E is in each case by such an angular range 16, 16 ', 16 "of the contour disc 1, in which both contours 11, 12 a survey 11 b and 12b have. Because in this case, both the outside door handle as well the door inner handle is coupled to the lock so that the door is activated both by actuation the outside door handle can be opened as well by pressing the inside door handle.

In the angular region 17 of the contour disc 1, the locked state V represents, has only the outer contour 11 a survey 11 b. Accordingly, the door can be opened only by pressing the inside door handle, while opening the door by pressing the outside door handle is impossible.

Conversely, in the lock state "child resistant", by the angle range 19 of the contour disc 1 is represented, only the inner contour 12 is a survey 12b, so that the door only by pressing the door outer handle but not by Operation of the door inner handle can be opened.

In the section or angular region 18 of the contour disc 1, the state "theft-proof" corresponds, is finally in any of the two contours 11, 12 a Survey provided. Accordingly, the door lock can be in this state neither with Use the outside door handle with the inside door handle to open the door.

FIGS. 2 a and 2 b show how the contour disk 1 shown in FIG is scanned by means of two coupling elements 4, 5, wherein the one coupling element 4 the outer contour 11 and the other element 5, the inner contour 12 scans.

Each of the two coupling elements 4, 5 consists of a coupling rod 40 and 50, the is arranged radially with respect to the contour disc 1 and at its the contour disc 1 facing end with a in the corresponding contour 11 and 12 respectively engaging pin 41 and 51 is provided. At their facing away from the contour disc 1 Ends are the coupling rods 40, 50 opposite to each with a T-shaped Recess 42 and 52 provided. About these recesses 42, 52 extends transversely to Extension direction of the coupling rods 40, 50 each have a connecting member 60, 70, the engages with a pin 61 and 71 in the associated recess 42 and 52, respectively. about the one link 60 is the inside door handle with the door lock and on the another link 70 of the outside door handle coupled to the door lock. At a Operation of the inside door handle or the outside door handle for the purpose of opening the Door via the corresponding link 60 and 70, a transmission of Actuation on the door lock to open by acting on the door lock to allow the door. In this case, the corresponding link 60 moves or 70 in an actuating direction B transversely to the direction of extension of the coupling rods 40.50.

However, this movement is only possible if the pin 61 or 71 of the respective connecting member 60, 70 in a section 43, 53 of the recess 42nd or 52 (see also Figure 3) protrudes, the movement of the connecting member 60th or 70 in the direction of actuation B transversely to the direction of extension of the coupling rods 40, 50 permits.

In the plan view of Figure 2b is based on the door outer handle assigned Coupling rod 50 clearly that the T-shaped recess 52 has a first portion 53rd forms, a movement of the connecting member 70 in the operating direction B transverse to the extension direction of the coupling rod 50 permits, as well as a second section 54, the movement of the connecting member 70 in the direction of actuation B not allows. Because of the connecting member 70 down the recess 52 projecting Pin 71 is blocked with respect to movement in the direction of actuation B, when it is in the latter portion 54 of the recess 52.

On the basis of Figures 2a and 2b is further clear that the coupling rods 40, 50 in be guided radially outward when their pin 41 or 51 in a Elevation 11 b and 12 b of the respective contour 11, 12 is located. In this state, in FIG. 2b shows, by way of example, the coupling rod 50 assigned to the outside door handle is shown, the associated link 70 engages with its pin 71 in those Section 53 of the recess 52 a, which is a movement of the connecting member in the Actuation direction B allows. So then the outside door handle on the link 70 coupled to the lock such that the door by pressing the Open outside door handle.

The same applies in the state shown in Figure 2a and 2b for the door inner handle, there also associated with the door inner handle coupling rod 40 with its pin 41 in a survey 11 b of the associated contour 11 engages the contour disc 1.

Now, by a rotation of the contour disc 1 along the direction of rotation D of the pin 41, 51 of one of the coupling elements 4, 5 in a portion of the associated contour 11, 12th led, which forms no survey, so gets the corresponding pin 61 and 71 of the associated link 60, 70 in a portion 44, 54 of the respective Recess 42, 52, a movement of the connecting member in the actuating direction B locks. The corresponding actuator (door handle or Outside door handle) is then decoupled from the door lock, so that the door is not through Let open operation of this actuator.

FIG. 3 shows a further specific embodiment of FIG. 1a schematically shown contour disc 1 shown. This is a modification of the in the figures 1b, 2a and 2b illustrated embodiment. Therefore, in the Only the differences from this embodiment explained below. Matching components are each provided with the same reference numerals.

In the embodiment of a contour disc 1 shown in Figure 3 is in the disc-shaped base body 10 only a contour 13 is provided, which consists of a circumferential guideway 13a, which is a plurality in the circumferential direction Has spaced apart, radially outwardly protruding elevations 13b.

In this contour 13 engage two coupling elements 4, 5, each with a pin 41 and 51st a disposed along the periphery 15 of the contour disc 1 spaced from each other are. As a result, the two coupling elements 4, 5 each feel different Regions of the contour 13 from.

In the state shown in Figure 3, both coupling elements 4, 5 engage with their pins 41, 51 in a survey 13b of the contour 13 a. The locking device is located Accordingly, in the unlocked state in which the lock both by means of Türinnenöffners and operated by means of the door outside opener to open the door can be. This can be seen in FIG. 3 from the fact that both connecting members 60, 70 with their pins 61, 71 respectively in such a section 43 or 53 of the associated Recess 42, 52 of a coupling rod 40, 50 engage that movement of the respective connecting member 60, 70 in the direction of actuation B is possible.

From this position, the contour disc 1 in the direction of rotation D in Turned clockwise so far that the two coupling elements 4, 5 in the in Figure 3 dashed lines engage in the contour 13 of the contour disc 1, so another situation arises with regard to the coupling of the actuators the locking device to the door lock. (In Figure 3 is the clarity Half selected a representation in which the position of the two coupling elements 4, 5 relative was rotated to the contour disc 1 counterclockwise. Actually Of course, the contour disc 1 is rotated clockwise and the two coupling elements 4, 5 remain spatially unchanged. As it is, however, for the determination of lock states only on the relative position of the contour disc 1 with respect to the coupling elements 4, 5th arrives, the simplified representation selected in FIG. 3 is permissible.)

In the state shown by dashed lines in Figure 3, a coupling element 4 engages in a Section 13a of the contour 13, which forms no survey, while the other coupling element 5 engages in a section 13b of the contour 13, which has a radial elevation forms. As a result, one of the actuators is decoupled from the door lock, while with the other actuator the door lock to open the door can be operated.

Since in the dashed line indicated in Figure 3 state only the Door outside opener associated coupling element 5 in a survey 13b of the contour 13th engages, can be in this state, the door exclusively by pressing the Open the outside door handle. It is therefore the lock state "child-proof".

Finally, FIG. 1c schematically shows an embodiment of a contoured disk 1 with only three different lock states, e.g. the unlocked State E, the locked state V and the lock state "theft-proof" S are determinable. Each of these states E, V, S is a section or angular range 16, 16 ', 17, 18 of the contour disc 1 assigned. Here are for the unlocked state E two sections or angular ranges 16, 16 'is provided, so that in a direction of rotation D of the contour disc 1 every second section or angle range associated with the unlocked E. This ensures that upon rotation of the Contour disc 1 in direction of rotation D to each of the unlocked state E different Lock state V, S always immediately followed by the unlocked state E.

Also in this figure is schematically coupled to the contour disc 1 drive M shown, which is provided for rotating the contour disc 1.
