Definitions

  • Motor vehicle lock in particular motor vehicle door lock
  • the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and a pawl, and with a locking element for blocking the locking mechanism when acceleration forces of a predetermined size occur, for example in the event of an accident, the locking element having a pin on the locking mechanism interacts.
  • motor vehicle locks and in particular motor vehicle door locks with a locking mechanism consisting essentially of a rotary latch and a pawl are exposed to high acceleration forces in the event of a crash, it is particularly important to prevent the locking mechanism from being opened unintentionally.
  • the locking mechanism consisting of a rotary latch and pawl assumes its closed position during normal operation of the associated motor vehicle. To ensure that this closed position is maintained even in the event of a crash, various measures are known in the prior art.
  • the procedure is such that an anti-rotation device is provided, which prevents the locking mechanism from opening due to shock or impulse.
  • the anti-rotation device can have one or more locking fingers and/or locking stops, which are assigned to a blocking lever or release lever.
  • the blocking lever ensures that the pawl is blocked in its locking positions.
  • the locking mechanism can be opened using the release lever.
  • the anti-twist device is designed overall in such a way that the blocking lever is blocked in the event of a movement caused by a shock or impulse. Blocking the blocking lever can cause The locking mechanism cannot be opened unintentionally because this requires the blocking lever to be lifted out of its position blocking the pawl. This is relatively technologically complex.
  • the procedure is such that a locking element is deflected by the acceleration forces observed, for example, in an accident.
  • the locking element engages the locking mechanism and holds it in place even after the acceleration forces have disappeared until an actuating lever mechanism acts on the locking mechanism again for the first time.
  • a functional crash barrier is made available, while at the same time creating the possibility of trouble-free and easy operation of the motor vehicle door lock after the crash has ended.
  • the locking element is designed in two parts with a blocking pawl and a ground lever.
  • the blocking pawl and the mass lever are rotatable and mounted on the same axis as each other.
  • a relatively complex construction is provided, as it also requires the ground lever and the blocking pawl. This means that malfunctions cannot be completely ruled out.
  • the invention is based on the technical problem of a motor vehicle lock and in particular a motor vehicle door lock as described above To further develop the design so that an effective crash barrier can be implemented in a simple manner, taking into account a functional and long-lasting structure.
  • the invention proposes in a generic motor vehicle lock and in particular a motor vehicle door lock that the locking element is designed as a recess in a lock case supporting the locking mechanism, into which the pin dips when the locking mechanism is deflected due to acceleration.
  • the invention is initially based on the knowledge that an additional locking element or a supplementary blocking pawl including a ground lever, as in the generic prior art according to EP 2 633 140 B1, is fundamentally unnecessary.
  • the function of the mass lever including the blocking pawl is ultimately taken over by a locking element.
  • the locking element can be the rotary latch and/or the pawl as part of the locking mechanism.
  • the locking element in question is equipped with the pin arranged thereon, if the deformation or displacement of the locking element in question is observed due to acceleration forces occurring, the pin provided on the locking element will dip into the recess. The result of this is that the relevant locking element is blocked and consequently the locking mechanism does not open unintentionally.
  • the locking mechanism or the locking element equipped with the pin can return to its undeflected normal position. This also corresponds to the fact that the pin leaves the recess in the lock case supporting the locking mechanism. This means that the lock is free again and is no longer blocked. I.e., after the elimination of the Acceleration forces are restored to normal functionality
  • the design is such that the pin and the locking element equipped with it are manufactured separately from one another. As a result of the separate production, the locking element and the pin are then combined with one another. This can be done and realized according to the invention by connecting the pin to the relevant locking element.
  • the pin can be riveted, welded, screwed or otherwise preferably permanently connected and coupled to the locking element.
  • the procedure is such that the pin and the locking element are manufactured together.
  • the pin can be stamped into the locking element or generally integrated.
  • the locking element may be loaded with a stamp, which defines the pin by deep drawing or stamping in the locking element.
  • the locking element equipped with the pin can be the pawl, the rotary latch or both.
  • the design is such that the pin is arranged on the rotary latch.
  • the invention is based on the knowledge that the rotary latch is typically equipped with a load arm and a catch arm, which define an inlet mouth between them for the locking bolt that moves in and is caught therein.
  • the motor vehicle lock is arranged in or on an associated motor vehicle door, whereas the locking bolt is mounted on the body side.
  • the locking bolt caught in the inlet mouth of the rotary latch ensures that the locking bolt moves, for example, in a longitudinal direction in relation to the associated motor vehicle.
  • the rotary latch is also displaced in this longitudinal direction.
  • the rotary latch is typically equipped with the pin in question on its load arm, the overall design can be such that when the rotary latch is displaced in the relevant longitudinal direction, the pin engages in the recess. This can largely be done in a form-fitting manner.
  • the procedure here is usually that both the pin and the recess are polygonal.
  • the pin and the recess may each be designed to be triangular.
  • the pin and the recess are generally arranged in the longitudinal direction of the motor vehicle when installed. If there is a crash or frontal crash and thus increased acceleration forces acting in this longitudinal direction, the locking bolt is moved relative to the rotary latch equipped with the pin. As a result of this, the rotary latch also experiences at least a slight movement in this longitudinal direction.
  • the rotary latch Since the rotary latch is equipped with the pin arranged thereon, its movement in this longitudinal direction corresponds to the pin engaging in the recess in the lock case.
  • the recess is arranged in such a way that the pin can engage in it when the locking mechanism is in the closed position, but otherwise (i.e. outside the closed position) no interaction is observed. This happens in any case as long as the acceleration forces act on the locking bolt and thus also on the rotary latch. After the increased acceleration forces have disappeared, the rotary latch can then be removed with its pin from the recess or moves back to its normal position and the normal functionality of the locking mechanism is then restored. This is where the main advantages can be seen.
  • FIG. 1A and 1B show the motor vehicle lock according to the invention in the form of a motor vehicle door lock in different views and
  • the figures show a motor vehicle lock, which according to the exemplary embodiment is a motor vehicle door lock. This is reduced to the elements essential to the invention.
  • 1A first of all shows a lock case 1 made of generally high-strength steel, in which a locking mechanism 2, 3 consisting of a rotary latch 2 and a pawl 3 is mounted.
  • the locking mechanism 2, 3 can interact with a locking bolt 4.
  • the overall design is such that the lock case 1 is connected to a motor vehicle door, not shown in detail.
  • the locking bolt 4 is found on the body side, i.e. it is connected to a motor vehicle body (not shown), for example screwed to it.
  • the design is such that the locking bolt 4 in the schematic sectional view according to FIG. 1 B moves in a longitudinal direction X hits an obstacle. Then high acceleration-related inertia forces occur in the said longitudinal direction X, which are shown in FIG. 1B by the relevant arrow
  • a locking element 5 is provided according to the invention.
  • the locking mechanism 2, 3 is equipped with a pin 6, which interacts with the locking element 5, as will be explained in more detail below.
  • the locking element 5 in the context of the invention is a recess 5 in the lock case 1 supporting the locking mechanism 2, 3.
  • the pin 6 can therefore dip into the recess 5 in question when the locking mechanism 2, 3 is deflected due to acceleration. This applies at least when the locking mechanism 2, 3 assumes its closed position - as shown.
  • the pin 6 is arranged on the rotary latch 2, as shown in the two exemplary embodiments in FIGS. 2A and 2B.
  • the pawl 3 can also be equipped with such a pin 6. It is also within the scope of the invention to equip both the pawl 3 and the rotary latch 2 with their own pin 6, which, however, is not shown.
  • the pin 6 and the locking element 2, 3 equipped with it, specifically the rotary latch 2 can be manufactured separately from one another and combined with one another. This can be seen in FIG. 2B in the variant shown there. At this point you can see that the pin 6 is manufactured separately from the rotary latch 2 and is combined with it. This can be done by riveting or welding the pin 6 to the rotary latch 2 or coupling it in some other way, as already described in the introduction.
  • the procedure is such that the pin 6 and the relevant locking element 2, specifically the rotary latch 2, are formed in one piece.
  • the pin 6 and the locking element in question or the rotary latch 2 are manufactured together. This can be done by stamping the pin 6 into the rotary latch 2.
  • the pin 6 is not only provided on the rotary latch 2 within the scope of the exemplary embodiment. But in addition, the design is such that the pin 6 is arranged on a load arm 2a of the rotary latch 2.

  • the rotary latch 2 like the pawl 3, can be made of high-strength steel.
  • the rotary latch 2 can be deformed with a corresponding deep-drawing die, which ensures that the pin 6 protrudes relative to a surface of the rotary latch 2 on the load arm 2a.
  • This surface of the rotary latch 2 is the one that is deformed or moved in the longitudinal direction X in the direction of the lock case 1 supporting the locking mechanism 2, 3 in the event of a crash. This is ensured by the locking bolt 4, which is also displaced in the relevant longitudinal direction X and is caught by the locking mechanism 2, 3 in the closed position.
