  • the lever-like signal element 34 is in the direction of arrow C (see FIG. 14 ) loaded spring force, wherein the signal element 34 then in the in FIG.
  • the lever-shaped immobilizing element 31 is rotationally coupled to the rotary latch 4 via the adjusting element 47, whereby a rotational movement of the rotary latch 4 from the closed position to the open position, the stop edge 48 of the immobilization element 31 moves away from the rotary latch jaw 6.
  • the movement coupling instead of the catch 4 with the pre-latching lever 26, the pawl 7 or even the drive element 11.
  • a motor vehicle door lock 1 has been presented, which is characterized on the one hand by the fact that the noise during opening is reduced to a minimum and in particular the noise is minimized in the discharge stroke. This is achieved in that the pawl 7 and the rotary latch 4 are moved to each other during the opening process such that the tailgate and thus the vehicle door latch 1 can remove relative to the closing element 2, whereby the pressure on the tailgate pressure or the bias of the tailgate is first reduced before the pawl 7 and the catch 4 finally disengage to release the closure member 2.
  • this is achieved by the hinge axis 20 is moved relative to the axis of rotation 5 of the rotary latch 4 during the opening process, whereby the initially tangential movement to the rotary latch 4 and then the radially away from the rotary latch 4 pioneering movement of the locking portion 8 of the pawl 7 is implemented.
  • the motor vehicle door lock 1 is characterized by a drive requiring a small installation space. This is possible because with the onset of movement of the pawl 7 from the engaged position to the open position the Pawl 7 is no longer spring-loaded by the spring element 38. The pawl 7 is acted upon exclusively in the engaged position by the force of the spring element 38 and decoupled with the onset of movement from the engaged position to the open position of the spring element 38.
  • the drive element 11 and the lever-like signal element 34 cooperate to detect the engagement position and the non-engagement position, whereby only one sensor 36 is used to detect or detect the position of the motor vehicle door closure 1 - instead of two as in the prior art Sensors - needed.
  • the motor vehicle door lock 1 also has an immobilization element 31 with which the closing element 2 is secured without applying an additional force while suppressing rattling noises in the rotary latch jaw 6.
  • the immobilization element 31 is in this case motion-coupled with the rotary latch 4, so that the immobilization element 31 occupies different positions as a function of the open-closed position.
  • a method for opening the motor vehicle door lock 1 in which the pawl 7 and the rotary latch 4 are disengaged for opening by the pawl 7 is at least partially pivoted away from the rotary latch 4.
  • the pawl 7 is moved by the drive member 11 during movement from the engaged position in the direction of the release position such that in this movement with the pawl 7 still engaged rotary latch 4 is moved in the direction of the open position.
  • the drive member 11 is rotated to open the motor vehicle door latch 1 such that the pawl 7 or at least a portion of the pawl 7 is first moved during movement from the engaged position in the direction of the release position substantially tangentially with respect to the rotary latch 4 and then to the Pawl 7 and the catch 4 to disengage, is moved by the rotary latch 4 substantially radially away.
  • the drive member moves the pawl during movement from the engaged position towards the release position such that during this movement with the pawl still engaged rotary latch moves in the direction of the open position. Due to the release mechanism of the motor vehicle door lock, the pawl and the rotary latch during a movement operation of the pawl are still engaged in the direction of the release position. Although this movement of the pawl does not allow the opening of the tailgate. However, by this (first or initial) movement during the opening process, the bias of the tailgate degrades, since the defined movement of the pawl causes a relative movement between the motor vehicle door lock and the closure element and thus a discharge of the tailgate, wherein the rotary latch to a predetermined rotational movement in the open position is turned.
  • the invention provides that the bias between the tailgate or motor vehicle door lock and closing element is reduced before the pawl and the rotary latch are disengaged.
  • the motor vehicle door lock 1 of the type mentioned above is inter alia characterized in that the pawl 7 is subjected to force only in its engaged position and the application of force holds the pawl 7 with the catch 4 in engagement.
  • the merely engaged position of the pawl allows the use of a motorized opening aid that only has to apply the force required to move the pawl to the open position.
  • the pawl can only in Engagement position be spring force loaded. Once the pawl is moved out of the engaged position, no spring force acts on the pawl. In this case, no additional force to overcome a possible spring force is then required.
  • the pawl undergoes a kind of load change in its movement from the engaged position to the release position, wherein outside the engaged position, the pawl is not spring-loaded.
  • the pawl is spring-loaded outside its engaged position, so that in addition to the force of the actual movement of the pawl, an additional force to overcome the acting spring force had to be applied for pivoting in the open position.
  • This is no longer necessary, so that a motor drive with lower power can be used to operate the motor vehicle door closure.
  • a motor drive with lower power can be used to operate the motor vehicle door closure.
  • a smaller motor can be used, so that overall the space of the motor vehicle door lock fails smaller and the motor vehicle door lock is made more compact.
  • the costs for producing the motor vehicle door closure are reduced.
  • an abutment region 37 formed on the locking pawl 7 in the engaged position can be pressed against a stop element 38 such that a latching section 8, which is formed on the end of the pawl 7 opposite the abutment region 37, acts in the direction of the rotary latch 4 is.
  • the stop element By pressing the stop element against the contact area, the pawl is rotated about the hinge axis such that a latching portion of the pawl is urged into the engaged position.
  • the stop element 38 may be formed as an elastic stop surface.
  • the stop element is designed as a spring element 38, wherein in the closed position, a first leg 39 of the spring element 38th pressed against the contact surface 37 of the pawl 7 and a second leg 40 is fixedly supported on a housing member 3 of the motor vehicle door latch 1, and wherein upon movement of the pawl 7 from the engaged position, the first leg 39 of the spring member 38 is brought out of engagement with the contact surface 37 ,
  • the invention provides for the immobilization element in the motor vehicle door lock.
  • the immobilizing element By the immobilizing element, the closing element is clamped in the closed position of the rotary latch between the rotary latch and the immobilizing element, so that a relative movement of the closing element with respect to the rotary latch, which is the cause of the disturbing rattling noise, is prevented. So that the clamping force does not interfere with the opening of the motor vehicle door lock, the immobilizing element is coupled with the rotary latch, which ensures that during a movement of the rotary latch from the closed position to the open position, the immobilizing element is moved accordingly and releases the closing element.
  • the immobilizing element 31 which clamps the closing element together with the rotary latch in its closed position, it is provided that the immobilizing element 31 is coupled with the rotary latch 4 in such a manner that upon movement of the rotary latch 4 in the direction of the open position to release the closing element 2, the immobilization element 31 pivots away from the rotary latch 4. In this way, it is ensured that the immobilizer element is only in the corresponding position when the closing element is to be actually kept motion-inhibited.
  • the movement coupling of rotary latch and immobilization element can be realized in a simple constructive and mechanical manner, characterized in that the rotary latch 4 has a radially offset to its axis 5 arranged adjusting element 47, which in a movement of the rotary latch 4 in the direction of the open position, the immobilization element 31 of the rotary latch 4 pushes away.
