Description

The present invention relates to a motor vehicle locking system according to the The preamble of claim 1 or claim 7.

DE 100 01 415 C1, which forms the starting point of the present invention, discloses a motor vehicle locking system with an electric motor openable Motor vehicle lock and an electrically operated child safety lock.

So far, each electrically openable motor vehicle lock from safety or For redundancy reasons associated with a manually operable opening mechanism, so that the motor vehicle lock in case of failure of the electrical system basically from the inside remains mechanically openable. For child safety is this opening mechanism lockable by electric motor. Electromotive blocking is expensive, as a motor, a gearbox and possibly additional levers are required.

The term "motor vehicle lock" is in the present invention primarily to understand a side door lock of a motor vehicle. However it can also a tailgate lock, a hood lock or a flap lock one Act motor vehicle.

The term "child safety device" in the present invention is a optionally blocking an inside opening of a motor vehicle lock and thus the associated motor vehicle door, in particular for the protection of Children against unwanted or careless opening, to understand.

The present invention is based on the object, a motor vehicle locking system specify a comfortable child safety lock with simple and cost-effective construction is made possible.

The above object is achieved by a motor vehicle locking system according to claim 1 or claim 7 solved. Advantageous developments are the subject of Dependent claims.

A basic idea of the present invention resides in the motor vehicle lock Assign a manually operable from the inside opening mechanism, by the parental control manual, and only manually blokkierbar is, the parental control otherwise electrically effective and ineffective is to be set, thus so far only electrically and mechanic-free is working. The term "blocked" or the term "blockable" is in the Meaning of the teaching of the present invention to understand functionally. constructive this can be realized by a mechanical blocking in such a way that the manually operable from the inside opening mechanism, except for tolerances and inherent elasticities of the power train, no longer moving can be. More common is the realization of a freewheel circuit, so that the manually operable opening mechanism in the position "child-proof" easy makes an idle stroke and remains ineffective.

An alternative idea of the present invention resides in the motor vehicle lock from the inside electrically open form, with the child safety by means of a particular accessible to a driver switch optionally permanently switched on or off.

Preferably, the child safety device is temporarily deactivated in the switched-on state, so that during the period of such deactivation an occupant despite activated child safety lock the actually child-safe motor vehicle door can open by actuation of the inner actuator, without opening the vehicle door from the outside is required.

In the figures, the same reference numerals for the same or similar parts used, with corresponding or comparable properties and advantages be achieved, even if a repeated description is omitted.

Fig. 1 shows a schematic representation of a motor vehicle 1 with a proposal Motor vehicle locking system 2 with preferably several Motor vehicle locks 3, in particular side door locks for side doors 4. The arrows in Fig. 1 indicate the approximate mounting positions of the illustrated Motor vehicle locks 3 in the motor vehicle 1 at.

Each motor vehicle lock 3 is preferably motor, in particular electric motor in training as a so-called electric lock, openable. For example can an indicated in Fig. 2 drive 5, such as an electric motor, for Opening a pawl, not shown, lift out, in the closed state For example, lock a rotary latch, not shown. however can the motor vehicle locks 3 also powered by other motor or be pneumatically openable, for example. Preferably that is Open, however, each electrically controllable.

Fig. 2 shows a schematic representation of a first embodiment of the proposal Motor vehicle locking system 2, namely a motor vehicle lock 3 on an associated motor vehicle door 4.

The motor vehicle locking system 2 has an internal operating element 6 which from an operator, not shown in the interior or passenger compartment of the Motor vehicle 1 is actuated to the associated motor vehicle lock 3 means of the drive 5 to open. The inner actuator 6 is accordingly in particular associated with the respective motor vehicle door 4, preferably arranged on the inside.

The inner operating element 6 allows an electrically controlled opening of the Motor vehicle lock 3. Preferably, the inner actuating element 6 as electric pushbutton, changeover switch, microswitch or other sensor trained or provided with it. Instead of a manual operation of the inner actuator 6 may also be a touch or even approach suffice. The inner actuator 6 and this associated components So lead in the normal state in an operation to an electrically controlled Opening the associated motor vehicle lock 3 by means of the drive 5th

The motor vehicle locking system 2 further comprises a child safety device 7, the in the set or switched-on state causes the motor vehicle lock 3 and thus the vehicle door 4 can not be opened from the inside. This will be discussed later.

In the first embodiment, the motor vehicle locking system 2 has a from the inside manually operable opening mechanism 8, in particular from Safety or redundancy reasons is provided, so that the motor vehicle lock 3 in case of failure of the electrical system basically mechanically openable from the inside remains. The opening mechanism 8 allows in particular a mechanical lifting a pawl, not shown in the motor vehicle lock. 3

The opening mechanism 8 is manually operated from the inside, for example by means of the internal actuating element 6, or - as indicated in Fig. 2 - by means of a separate internal actuating lever 9, another handle o. The like.

The opening mechanism 8 is - in particular only when the vehicle door is open 4 - manually blocked, in particular by a locking lever 10 o. The like. Im blocked state, therefore, the vehicle door lock 3 is no longer inside mechanically openable. In that regard, the term is blocked or blockable, to understand functionally. Constructively, this can, as shown, by a mechanical Blocking be realized so that the internal operating lever 9 is not more can be moved. But it is equally possible, often preferred, one Free-wheeling circuit, so that the internal operating lever 9 in the position "child-proof" performs an idle stroke.

Accordingly, the child safety device 7 includes the only manually operable Locking lever 10 or other only manually operable locking mechanism (or idle stroke mechanics). The blocking of the opening mechanism 8 takes place So not motor, as otherwise in the prior art at a Electric lock common, but only manually. This saves a drive.

The locking lever 10 is preferably a microswitch 11 or other sensor assigned, so that the manual locking of the opening mechanism 8 detectable is.

The motor vehicle locking system 2 here and preferably has a central or decentralized, possibly including several modules or components Control device 12. The inner actuator 6 and the microswitch 11 or another sensor are connected to the control device 12.

Upon actuation of the inner actuator 6, an opening signal is generated detected by the control device 12 only as drive or Opening signal to the motor vehicle lock 3 and its drive 5 forwarded or is output when the parental lock function is turned off or deactivated or deactivated. The control device 12 provides Accordingly, a working exclusively electrical and mechanical Part of the child safety device 7.

When switched on or effectively set child safety 7 gives the controller 12 no opening or drive signal to the motor vehicle lock. 3 or its drive 5, even if the inner actuator 6 of a not shown vehicle occupants is actuated.

Said, electrically operated child safety function is preferably automatically turned on when the manual blocking of the opening mechanism 8 has been detected by means of the microswitch 11 or other sensor. Corresponding is the child safety device 7 or the electrically operated child safety function automatically turn off again when the manual override Blocking the opening mechanism 8 is detected.

Alternatively or additionally, the electrically operated child safety function by means of a vehicle driver, not shown in particular and / or passenger accessible switch 13 either on or off be.

According to a particularly preferred embodiment, the electrically working Child safety function, in particular by means of one for one not illustrated driver and / or passenger accessible switch, buttons 14 o. The like., Temporarily deactivated, so that during the period of such deactivation - So in particular during the switch 13 in a parental control function einschaltenden position is - upon actuation of the inner actuator 6, the motor vehicle lock 3 opens electrically.

The parental control function is thus temporarily disabled only electrically or settable. This is advantageous, for example, when the driver a vehicle occupant getting out of the principle by the parental control function allow from the inside not openable motor vehicle door 4 want. An opening of the motor vehicle lock 3 from the outside is in the proposal Solution not required; rather, in this case, a vehicle occupant open the motor vehicle lock 3 from the inside and out of the vehicle 1 get off.

The temporary deactivation preferably takes place only for a predetermined, in particular, predefinable time duration, only during an actuation of the button 14 and / or only for a single opening of the motor vehicle lock. 3

The button 14 is designed in particular as a push-button, so that preferably in general only a temporary deactivation of the child safety device 7 - so the electrically operated child safety function - is possible. This can be prevented be that the parental control function unintentionally permanently disabled becomes.

Preferably, the (temporary) deactivation of the parental control function - In particular by means of the button 14 - optionally for the rear right or left Rear door 4, for both rear doors 4 and / or for the passenger door 4 done.

In addition, when the child safety device 7 is switched on deactivation is preferred displayed, in particular by means of a preferably for the driver well visible light 15 or other indication.

It should be noted that the drive, signal generation and processing respectively usually carried out electrically or electronically. For reasons of simplification is not in the present invention between electric and electronically distinguished. Rather, the term "electric" should also be a electronic or software-based control, evaluation, processing, Signal generation u. Like. Include.

Hereinafter, with reference to FIG. 3, a second embodiment of the proposal Motor vehicle locking system 2 explained. Here are only essential Differences of the second embodiment from the first embodiment highlighted. Otherwise, at least essentially arise corresponding or comparable properties and advantages.

In the second embodiment, no opening mechanism 8 is provided. The motor vehicle lock 3 is therefore generally not mechanically open from the inside. This allows a particularly simple and therefore cost-effective design.

The complete abandonment of an otherwise for safety and redundancy reasons provided mechanical Öffenbarkeit the motor vehicle lock. 3 from the inside is therefore responsible, because in a mechanically acting child safety In any case, the case may occur that the motor vehicle lock 3 mechanically not openable. Accordingly, the child safety device 7 works the second embodiment only electrically - ie without moving Parts and mechanic-free. This allows a further simplification of the structure. For optional permanent on and off the child safety lock 7 is at the second embodiment of the switch 13 is required.

Instead of the switch 13 can be switched on and off in both embodiments in any other way, in particular by the driver, controllable be, for example, by a software-based control function o. The like., which realizes the function of the switch.

The proposed motor vehicle locking system 2 is preferably for Rear doors 4 of the motor vehicle 1 a rear door and / or for a passenger door. 4 used.
