Definitions

  • the lever on the bearing pin side is connected to the lever carrying the locking surface by means of a pawl joint which is formed by a spherically shaped nose on the lever carrying the locking surface, which in a suitable joint socket on the bearing pin-side lever.
  • a stop lug is formed on the lever carrying the locking surface, which is clamped over by the lever on the bearing pin side and which, when the pawl arrangement opens, moves from the locking position stop into the kinking stop of the lever on the bearing pin side.
  • both lugs of the lever carrying the locking surface have sliding contact with the lever on the bearing pin side. This is a sliding friction to overcome, which requires a relatively large force for the actuation of the pawl until the catch is unlocked.
  • the lever carrying the locking surface is not only guided via a pin-slot connection, but is also still under the action of a spring. The disadvantages explained above also apply to this.
  • the invention has for its object to provide a motor vehicle door lock in which the pawl arrangement is very easy to move when the motor vehicle door is opened.
  • the pawl joint is designed as a pin joint and that the locking surface bearing lever at a distance from the locking surface has a bearing pin receptacle for the bearing pin, which has the locking position stop, and the switching stop with the switching stop, and that when the pawl arrangement is opened, the locking position stop is released from the bearing pin, and the bend stop comes to rest on the bearing pin.
  • the catch when the motor vehicle door is opened, the catch is unlocked by kinking the pawl arrangement.
  • the lever mechanism which forms the pawl arrangement, in the locked position strong, but can be easily bent when the pawl arrangement is unlocked. This can be achieved in various ways.
  • a preferred embodiment in which the pawl arrangement carries a tensile load in the locking position is characterized in this context in that the lever carrying the locking surface is designed as a two-armed lever, in which one lever arm the locking surface and the opposite lever arm beyond the pin joint, the bearing pin receptacle, and that the lever arm with the locking surface of the lever carrying the locking surface and the bearing pin-side lever are arranged one behind the other, and that the bearing pin receptacle on the opposite lever arm of the lever carrying the locking surface is designed as a fork, which includes the bearing pin and that Switching game defined, and that in the locking position with a mating surface contact of the locking surface and counter locking surface, the connecting line running in the plane of the pawl arrangement between the axis of the bearing pin, the axis of the pin joint and the contact line of the line contact which occurs at the beginning of the bend runs in a straight line.
  • the lever carrying the locking surface is designed as a one-armed lever which has the locking surface at one end and the pin joint at the other end, and in that in the area between the locking surface and the pin joint, the bearing pin receptacle is arranged in the form of a window which defines the switching game, and that the lever carrying the locking surface and the lever on the bearing pin side are superimposed are arranged, and that in the locking position with a mating surface contact of the locking surface and counter locking surface, the connecting line running in a plane parallel to the pawl arrangement between the axis of the bearing pin, the axis of the pin joint and the contact line of the line contact which occurs at the beginning of the bend runs in a straight line
  • the pawl arrangement it is expedient for the pawl arrangement to have a return spring arrangement which counteracts the buckling.
  • the invention is based on the knowledge that during the opening movement of the pawl arrangement, a rolling friction between the locking surface and the counter-locking surface can be initiated or superposed when the kink, if the one-piece and rigid pawl in the known embodiment is operated by a lever mechanism in the manner described and way is replaced.
  • the rolling friction significantly reduces the force required to initiate the pawl opening movement.
  • the further opening can be continued with surprisingly little force until the catch is unlocked because the kink between the lever on the bearing pin side and the lever carrying the locking surface increases as the opening movement of the pawl arrangement continues, the angle of Kink becomes smaller.
  • the motor vehicle door lock 1 shown in the figures has a rotary latch 3 which can be rotated about a pivot bolt 2 and a pawl arrangement 5, 6 which can be pivoted about a bearing bolt 4.
  • a lock holder 7 fastened to the door post of the motor vehicle fits into a lock holder recess in the rotary latch 3 one as shown in the figures. 1, 2 and 4 that the pawl arrangement 5, 6 in the closed state of the motor vehicle door with a blocking surface 8 engages a counter-blocking surface 9 on the catch 3 in the blocking position of the pawl arrangement 5, 6 with a mating surface contact.
  • the pawl arrangement 5, 6 is a lever mechanism with a bearing pin-side lever 5, which can be pivoted about the bearing pin 4, and one the blocking surface 8 supporting lever 6 executed.
  • the two levers 5, 6 can be bent against one another via a pawl joint 10 with a joint axis parallel to the bearing pin 4.
  • the lever 6 supporting the locking surface 8 is a two-armed lever and has a locking surface lever arm 11 and a lever arm 12 on the bearing pin side.
  • the pawl arrangement 5, 6 can be actuated via the so-called external actuation or the so-called internal actuation. From a comparative view of FIGS. 2 and 3 it can be seen that when the pawl arrangement 5, 6 is opened when the motor vehicle door is closed, the lever 6 carrying the locking surface 8 bends relative to the lever 5 on the bolt side and the blocking position stop 14 of the bearing pin receptacle 13 is released from the bearing bolt 4 and the bend stop 15 comes to rest on the bearing pin 4. This happens more or less suddenly. In this way, the mating surface contact, which can be seen in FIGS. 1, 2 and 4 between the blocking surface 8 and the counter-blocking surface 9, is converted into a line contact 16. This can be seen in Fig. 3. The line contact which arises when the pawl arrangement 5, 6 begins to buckle has also been indicated at 16 in FIGS. 1, 2 and 4.
  • 1 to 3 is the embodiment in which the pawl arrangement 5, 6 experiences a tensile load in the locked position.
  • the bearing pin-side lever 5 and the locking surface 8 carrying lever 6 with his Pawl lever arm 11 are arranged one behind the other that the bearing arm-side lever arm 12, of the lever 6 carrying the locking surface 8 with a fork, which forms the bearing pin receptacle 13 and defines the switching play.
  • 1 and 2 that in the locking position the connecting line 17 extending in the plane of the pawl arrangement 5, 6 runs between the axis of the bearing pin 4, the axis of the pawl joint 10 and the contact line of the line contact 16 in a straight line.
  • the locking surface 8 and the counter locking surface 9 are still in this locking position with a mating surface. 3 shows the conditions at the beginning of the bending movement.
  • FIG. 4 shows another embodiment in which the pawl arrangement 5, 6 experiences a pressure load in the locked position.
  • the peg-side lever 5 and the lever 6 carrying the locking surface 8 are arranged one above the other.
  • the bearing pin 4 includes a recess in the lever 6 carrying the locking surface 8, which represents the bearing pin receptacle 13 and defines the switching game.
  • the arrangement is such that in this locking position, the connecting line 17 running parallel to the level of the pawl arrangement 5, 6 runs between the axis of the bearing pin 4, the axis of the pawl joint 10 and the contact line of the line contact 16 in a straight line.
