Definitions

  • the present invention relates to a motor vehicle door lock with the features the preamble of claim 1.
  • motor vehicle door lock is to be understood comprehensively. There are not just side door locks and hatchback locks, but also, for example Tailgate locks covered by it. For the rest, the term motor vehicle door lock means the entire system, the components of which are also distributed could be.
  • Motor vehicle door locks are known in a variety of embodiments. Motor vehicle door locks with central locking drive are becoming increasingly common, Opening drive, auxiliary locking drive, all electric motor driven. An example of this can be found in EP 0 894 920 A1. at this motor vehicle door lock are on the locking elements and in the lock mechanism a variety of microswitches, partially designed as non-contact sensors, in particular Hall sensors, their signals be evaluated and implemented in a lock electronics.
  • a motor vehicle door or flap has one facing the outer wall of the door Damp room, in which moisture from above on the window shaft in frequent not insignificant amount occurs, and a separate and opposed mostly sealed drying room, directed towards the inside of the motor vehicle door or flap.
  • the locking elements are necessarily located are usually located on the front of the vehicle door or hatch.
  • the drying room there are electrical components and devices, for example Loudspeakers etc.
  • a damp room / dry room separation is for example already known for electric window regulators.

  • the control unit It is essential that the information of reaching the closed position or the Main latching position of the lock latch mechanically via the distance force transmission means is transmitted to the control unit. It is provided here that the movement of the lock latch into the closed position or the main rest position causes an actuating force on the removal power transmission means and that the resulting movement of the range transmission means can be evaluated in terms of circuitry in the control unit. This is done by means of a pulling function of the removal force transmission means in a first Direction of actuation of the closing element, in particular the pawl. By means of a pulling function of the distance force transmission means in one second direction, opposite to the first direction, is reaching the Locking position or the main latching position of the lock latch can be signaled mechanically.
  • the distance force transmission means with the closing element here the pawl, coupled including a two-way freewheel. This enables the lock latch with the pawl already engaged still a certain overstroke and possibly the pawl lagging when closing the motor vehicle door lock.
  • a large freewheel means that when in the closed position or in the main rest position lock latch to lift the pawl in principle the existing freewheel must be “bridged". This is particularly so against the background problematic that the operating forces on the outside door handle and should be as small as possible on the inside door handle to ensure maximum convenience to ensure. These low operating forces can be generally realize by an appropriate translation, so that a small Actuating force is "bought" by a large actuation stroke. It is obvious that against this background the above-mentioned freewheeling is problematic is.
  • Claim 7 shows a solution such as a large movement of the distance transmission means compared to the release movement of the pawl can be realized without having to put up with a freewheel.
  • a freewheel At in the lock position or the main latching position causes the latch an operating force on the distance power transmission means immediately an operating force on the pawl.
  • the freewheel is adjustable by an Intermediate element, which is coupled to the lock latch, largely avoided.
