  • an electromotive Opening aid for a pawl.
  • the electric motor of the drive unit due an opening signal energized, which, for example, on Outside door handle is generated.
  • a manual external actuation chain either does not exist at all or should only be used during emergency operation be effective.
  • the well-known electromotive Opening aid ensures that the operation of the door handle concerned is relatively easy, since only whose return spring must be deflected and a Actuation of the associated lock mechanism is unnecessary.
  • the motor opening or receives Closing aid no feedback on this not complete completed opening process of the locking mechanism.
  • the motor vehicle door may be damaged can open independently, without requiring an operation an internal and / or external operating lever required is.
  • this unintentional opening basically also while driving can not be excluded, revealed security problems for the vehicle occupants.
  • the invention aims to provide a total remedy.
  • the invention is based on the technical problem, a Motor vehicle door lock of the initially described Design to develop so that an unintentional Opening on the associated motor vehicle door in particular after an initiated electromotive opening process avoided at all costs.
  • the operating lever is in its position maintains and, moreover, the pawl in its depressed Position to release the catch remains and not - as in the prior art - in its closed position swings back.
  • the motor vehicle door lock according to the invention thus remains at not completely open Rotary catch in the functional position, which at full opened rotary latch is taken. This, anyway until this condition has been recognized. Then can the depressed pawl by a reversal of motion the drive unit (again) in its locking position convict.
  • these inventions ensure that that a not completely open rotary latch after example, open signal without doubt is detected and appropriate precautions result Has. This includes not just an ad in the display, but in particular the fact that the pawl depressed is held or the motor vehicle door lock its corresponding to the complete opening of the catch Maintains functional position.
  • the drive unit usually drives one Cam device, which acts on the actuating lever.
  • the cam device has at least two Cam, namely a lever cam for the operating lever and a position cam for a position measuring device.
  • a lever cam for the operating lever
  • a position cam for a position measuring device.
  • the lever cam With the help of the lever cam becomes the operating lever acted upon in the sense of opening the Gesperres.
  • an intermediary Lever for example, a trigger, in accordance Senses on the pawl.
  • the adjustment of the cam device can be adjusted overall hold and evaluate. It acts it is at the position measuring device usually a On / Off switch, which of an operating contour on Position cams with fully opened catch - and only then - is triggered and otherwise unencumbered remains. Consequently, the position measuring device for it used, only with registered complete opening of the Turning the drive unit off.
  • the cam device is under interposition a spring to one acted upon by the drive unit Driven pulley connected.
  • This spring will when acted upon drive unit initially tense and only then transfers movements of the drive unit the cam device. This can be done by positive locking between the drive unit and the cam device in tensioned Spring done. The tensioned spring can then relax again when the lever cam releases the operating lever happened. With the relaxing of this spring goes the return of the actuating lever to its original position associated.
  • the cam device usually has an in a circular recess engaging in the driven pulley Circular segment disc, which can be addressed with the help of Spring supported against the circular recess.
  • the aforementioned nose can of course also arranged other components of the motor vehicle door latch be, as long as she just makes sure not fully opened catch the cam device is blocked. That is, the nose likes an independent one Lever, an accessory, an actuator, etc. be arranged and the drive unit and acted upon by her Components - not fully open Rotary catch - block. Basically, the invention comes also completely without such a nose, if the drive unit and acted upon by her components, in particular the cam device, directly from the lever, the auxiliary device, the actuator, etc. are set.
  • the nose is on one Locking lever provided, which usually exists anyway is.
  • This locking lever may be a Central locking levers act.
  • the nose-bearing locking lever sure that when not opened catch the cam device is blocked.
  • a motor vehicle door lock is provided whose position of the rotary latch is usually queried as it were after an opening signal.
  • the rotary latch, the drive unit and acted upon by her components such as the operating lever and the pawl in this functional position.
  • the aforementioned blockage of the drive unit and the components acted upon by it can also be performed by an independent element, for example by the already existing locking lever. This has the consequence that the status "open" of the motor vehicle door lock is as it were frozen or stored, although the catch (not yet) is not fully open. As a result, unwanted openings, as they can not be excluded in the prior art, reliably avoid.
  • the invention allows a slow opening of the associated door, for example in a narrow parking space.
  • This slow opening of the associated door is associated with a further advantage.
  • the associated drive reacts faster than the dynamics of the door, that is, if the door does not follow or can not follow the drive or the drive unit on the bottom line, it still does not come to so-called Vorrasthakeln, as is known in practice.
  • Vorrasthakeln as is known in practice.
  • a motor vehicle door lock is shown, which with a drive unit 1 for acting a Gesperres 2, 3 is equipped.
  • the drive unit 1 is used for motor Opening the lock 2, 3, although with this Drive unit 1 basically also closing movements of the locking 2, 3 can be displayed.
  • the locking 2, 3 after sending a keyless Opening signal ("Keyless-Go") to open.
  • Keyless-Go a keyless Opening signal
  • An associated one Motor vehicle door can subsequently easily and swung open without much effort. The especially for tailgates, but increasingly also for Side doors.
  • an actuating lever 4 is realized, which on the one hand is acted upon by the drive unit 1 and on the other hand on the lock 2, 3 works.
  • the cam device 5, 6, 7 has at least two cams 5, 6, namely a lever cam 6 for the actuating lever 4 and a position cam 5 for a position measuring device 8.
  • this position measuring device 8 is in the context of the embodiment to a On / off switch 8, which is acted upon by an actuating contour 5a on the position cam 5 with fully open rotary latch 2.
  • this actuating contour 5a on the position cam 5 does not come into contact with the switch 8 equipped with a probe, the switch 8 or the position measuring device 8 remains unencumbered, and accordingly can not send a signal to a merely indicated control device 9. This is the case when the catch 2 is not fully open.
  • the then blocked drive unit 1 is switched off after a predetermined period of time, which in turn provides the control device 9, which acts on the drive unit 1 accordingly.
  • the cam device 5, 6, 7 has, in addition to the lever cam. 6 and the position cam 5 additionally a circular segment disc 7, which in a circular recess 10 a Output disk 11 engages. This driven pulley 11 meshes with a worm wheel 12, which in turn from the drive unit 1 is rotated.
