Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism with a catch and pawl, a release lever for the pawl, and with at least one acting on the trigger lever drive, wherein the release lever is designed as engageable with the pawl and decoupled from this opening lever.
  • the known measures have basically proven, but are capable of improvement, especially as far as the open position of the catch is concerned.
  • misalignments of the output control curve and / or an unintentional energizing of an associated electric motor can lead to the known release lever is in a position in which the catch can not be closed because the pawl is blocked by the release lever.
  • the invention aims to provide a total remedy.
  • the invention is based on the technical problem of developing a motor vehicle door lock of the design described above so that when the catch is open, the associated motor vehicle door lock or a door connected thereto can always be closed under all circumstances. At the same time, the possibility should still be given of being able to display a quick release or quick release.
  • the invention proposes in a generic motor vehicle door lock, that controlled by the rotary latch bistable rocker lever during opening movements of the catch transfers the opening lever in its disengaged position.
  • the invention proposes in detail that the bistable rocker lever holds the opening lever in the unlocked position of the motor vehicle door lock or in the open catch additionally in this disengaged position or the disengaging position.
  • the bistable rocker arm releases the opening lever when the catch is closed and transfers it into its coupling-in position or engagement position.
  • the pawl has a preferably rectangular contour, the to the coupling connection with the opening lever of a thereto, that is, behind the opening lever, arranged pin is engaged behind.
  • the opening lever usually performs pivoting / lifting / lowering movements. For this purpose, it is connected to the drive in the sense of a crank. Through these crank movements, the aforementioned positions and displacements of said opening lever can be easily achieved.
  • One of the two stable positions of the relevant bistable rocker lever corresponds to the disengaging position of the opening lever or release lever.
  • the other stable position of the rocker arm is usually taken when the catch is closed. Because then the rocker arm is transferred by means of a cam provided on the drive in an opening lever releasing and engaging position. This position of the rocker arm thus belongs to the Einkuppel ein the opening lever.
  • Both above-described bistable positions of the rocker arm are spring assisted, by applying a tilt spring.
  • the rocker arm is designed as a pivotable two-armed intermediate lever pivotable about an axis located between the rotary latch and the opening lever. Because then it makes sense to carry out an arm of this intermediate lever as a spring arm, which acts on said tilt spring, while the other arm takes over the function of a stop arm. Because this stop arm carries end a stop pin, which in disengaging position of the opening lever to the opening lever strikes and holds it in the position in question.
  • the invention also allows a purely manual opening of the locking mechanism by For example, an (inner and / or outer) actuating lever directly or indirectly engages the pawl.
  • the invention ensures that a quick release or quick release of the motor vehicle door lock takes place or can take place by means of an electric motor with the aid of the drive acting on the release lever or opening lever. For as soon as the catch is in the closed position, the rocker arm is transferred to the opening lever releasing and engaging position. This is ensured by a cam on the drive.
  • a motor vehicle door lock is shown with its essential elements for the present invention.
  • this motor vehicle door lock has a locking mechanism 1, 2 with pawl 2 and rotary latch 1.
  • a release lever 3 for the pawl 2 which is designed in this case as with the pawl 2 detachable and decoupled from this opening lever 3.
  • one of the fundamental structure of acting on the release lever 3 drive 4, 5, 6, 7. Of course, in addition to this drive 4, 5, 6, 7 still another drive (for example, anti-theft drive with anti-theft lever) to be realized.
  • the drive 4, 5, 6, 7 is composed of an electric motor 4, a connected propeller shaft 5, a hereby meshing driven pulley 6 and finally a connected to the driven pulley 6 cam 7 together.
  • the driven pulley 6 is rotated by the electric motor 4 in rotation about its axis 8. Both clockwise and counterclockwise rotations are possible.
  • the basic structure further includes a rocker arm or intermediate lever 9, which is rotatably mounted about an axis 10 and two arms, namely a spring arm 9a and a stop arm 9b has.
  • the spring arm 9a is acted upon by a tilt spring 11 in a clockwise direction.
  • the trigger lever or opening lever 3 undergoes a spring action in a clockwise direction, as indicated by an indicated spring 12 is expressed (see Fig .. 3).
  • the stop arm 9b of the intermediate lever 9 is equipped at the end with a bolt 13 which rests in the illustration of FIG. 3 at the opening lever 3 and holds it in the disengaged position, as will be described in more detail below.
  • the pawl 2 is equipped with a rectangular contour 14, which is composed of a coupling piece 14a and a guide piece 14b.
  • a rectangular contour 14 which is composed of a coupling piece 14a and a guide piece 14b.
  • the coupling piece 14a-like the pawl 2 itself-runs essentially horizontally, while the guide piece 14b, by contrast, for the most part extends vertically.
  • a pin 17 arranged on the opening lever 3 or connected thereto also raises the pawl 2. Because this pin 17 engages the coupling piece 14a of the contour 14th on, so that the pawl 2 rotates counterclockwise about its axis 15 (see Fig. 2). As a result, the catch 1 comes free and rotates spring assisted clockwise about its axis 16 until the position to be recognized in Fig. 3 is reached.
  • the opening lever 3 performs so - acted upon by the drive 4, 5, 6, 7 in the counterclockwise direction - and its connection to the driven pulley 6 via a crank joint 18 as a combined combined pan / lifting movement. - Of course, corresponds to a rotation of the driven pulley 6 in a clockwise direction to a pivoting / lowering movement of the opening lever.
  • the bistable rocker arm 9 As soon as the rotary latch 1 moves into its open position in a spring-assisted manner, the bistable rocker arm 9 also rotates about its axis 10, which is arranged substantially between the rotary latch 1 and the opening lever 3. The rotation of the rocker arm or intermediate lever 9 from the position shown in FIGS. 1 and 2 (engagement position of the opening lever 3 or closing position of the rotary latch 1) into the functional position according to FIG. 3 (disengaging position of the opening lever 3 or open position of the rotary latch 1) is thus caused by the catch 1.
  • the motor vehicle door lock In the position of FIG. 3 with an open rotary latch 1, the motor vehicle door lock can be closed at any time. Any blockages are avoided just like sham closures.
  • This pin 13 can be transferred by means of the drive 4, 5, 6, 7 in a the engagement position of the opening lever 3 permitting position by the output disk 6 - starting from the position in Fig. 3 - sweeps in about half a turn clockwise.
