Definitions

  • 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 also with an actuating lever chain for the locking mechanism, which has at least one actuating lever and a securing element, the securing element closing the actuating lever chain in its “unlocked” position and opens in the “secured” position, and with at least one mass inertia element which, at least in the event of a crash, acts on the securing element to assume its “unsecured” position.

  • the actuating lever chain is additionally provided and ensures that the locking mechanism can be opened at least from the outside, for example if the electric motor drive fails.
  • the actuating lever chain for the locking mechanism is typically an external actuating lever chain. This enables redundant opening of the locking mechanism.
  • Such motor vehicle locks and in particular motor vehicle door locks are also and regularly in the locked state when an associated motor vehicle is in operation. This is usually done for reasons of safety for the passengers inside. However, if there is a crash and the acceleration associated with it, it is necessary for a motor vehicle door lock to be connected to the relevant motor vehicle door lock equipped motor vehicle door can be opened after the crash by, for example, arriving rescue personnel.
  • a kind of "emergency release” is implemented, which engages with a safety element designed as a locking lever.
  • the mass inertia element ensures, at least in the event of a crash, that the relevant securing element or the locking lever is transferred to its “unlocked” or “unlocked” position.
  • the associated motor vehicle door can then be opened as desired by arriving rescue personnel with the aid of the actuating lever chain that is then closed.
  • a motor vehicle lock is implemented for this purpose, in which the motor vehicle lock is unlocked and unlocked by rotating a driven pulley as part of an electric motor drive.
  • a blocking lever is provided, with the help of which unlocking of the locking mechanism can be prevented.
  • the mass inertia element upstream of the blocking lever now in turn prevents the blocking lever from being moved out of the blocking position, so that overall there is a high level of functional reliability because unintentional unlocking is prevented.
  • the invention is based on the technical problem of further developing such a motor vehicle lock and in particular a motor vehicle door lock in such a way that an emergency unlocking or emergency unlocking only takes place and takes place when the accelerations associated with the crash cannot (any longer) open the associated locking mechanism.
  • the inertia element does not act on the securing element immediately after the inertia element has been acted on, but with a time delay.
  • the delay element takes care of this.
  • the time delay is typically set and measured in such a way that the accelerations associated with the crash have subsided to such an extent that an unwanted deflection, for example of the outside door handle, can no longer take place as a result. It is conceivable in this context, with temporal Delays of the order of 1 to 10 seconds to work. Of course, this depends on the respective motor vehicle lock or motor vehicle door lock and the associated motor vehicle.
  • the invention is based on the assumption that a locking lever is typically acted upon by the mass inertia element or the interposed delay element as a locking element, namely in such a way that the locking element or the locking lever is “secured” or “locked” from its previously assumed position to the "unlocked position”. “ or “unlocked” position.

  • the inertia element alone, if necessary i. V. m. an associated control lever so that in the event of a crash, the delay element is first acted upon. Due to the time delay of this application achieved with the aid of the delay element, the delay element ensures after the previously mentioned period of time - and only then - that the securing element leaves its previously assumed “secured” position and is transferred to the "unsecured” position. This happens at least when the securing element has not previously taken up its “unsecured” position. In this way, the invention ensures that the mentioned and necessary “emergency unlocking” takes place and is carried out with an adjustable delay, as it were, after the crash. As a result, according to the invention, there is no longer (any longer) the risk that the emergency unlocking has taken place too early.
  • the actuating lever chain is not unlocked or unlocked in an emergency until the acceleration forces associated with the crash have subsided, so that an unwanted opening of the associated motor vehicle door is no longer observed.
  • the motor vehicle occupants optimally protected and, at the same time, given the possibility for arriving rescue personnel to open the associated motor vehicle door lock without any problems due to the delayed emergency unlocking. This is where the main advantages can be seen.
  • the delay element is not designed electrically or electronically. Instead, the delay element is advantageously a mechanical timer.
  • the invention is based on the finding that the function of an electrically or electronically operating delay element, like that of the previously mentioned electromotive drive, is not necessarily guaranteed or cannot be guaranteed in the event of a crash or afterwards. This is because the electrical energy supply is typically interrupted during or after such a crash. Although it is conceivable, the electric motor drive with an emergency energy source independently of the motor vehicle power supply to equip. If, however, according to the invention the delay element is designed as a mechanical timer, such an emergency energy source can be dispensed with.
  • the mechanical timer can be a rotary damper.
  • This rotary damper ensures that any rotary or pivoting movements of the mass inertia element or the control lever assigned to it are transmitted to the securing element or the locking lever with a time delay in the event of a crash.
  • the rotary damper can be filled with a viscous liquid, which causes a time delay in the rotary or pivoting movement performed by the mass inertia element and thus the rotary damper acts on the safety element with the desired time delay on the output side.
  • the rotary damper can also work against the force of a spring.
  • the spring may be a metal strip that can be wound up, for example. So it is conceivable that the rotational movement of the mass inertia element or the control lever is transmitted, for example, to a shaft of the rotary damper. If the spring or the metal strip that can be wound up encloses the shaft in question at a distance and is connected to it with one end, an optionally gear-assisted rotational movement of the shaft initially causes the metal strip or the spring to be wound up on the shaft in question.
  • the securing element can in turn and advantageously work on a coupling element as a further component of the actuating lever chain.
  • the safety element generally ensures that the coupling element "engages” in its "unlocked” position.
  • the securing element in its “secured” position ensures that the coupling element is “disengaged”.
  • the coupling element ensures that the actuating lever chain is mechanically closed, so that any action on the actuating lever chain using an outside door handle or an inside door handle can ultimately be transferred to the locking mechanism.
  • the actuation of the actuating lever chain corresponds to a release lever as a further component of the actuating lever chain lifting the pawl from its latching engagement with the rotary latch.
  • the rotary latch then opens with the help of a spring and releases a previously caught locking bolt. Accordingly, the associated motor vehicle door can be opened.
  • the clutch member is typically spring biased toward its engaged position. That is, the spring associated with the coupling element ensures that the coupling element assumes its engaged position without being acted upon by the securing element. Consequently, the securing element must work against the force of the spring assigned to the coupling element during the transition from its “unlocked” position to the “secured” position in order to be able to disengage the coupling element as a whole.
  • the overall design is such that the inertia element interacts with the energy store, which in turn is connected upstream of the delay element.
  • the invention thereby ensures that the spring relaxing, for example in the event of a crash, as part of the energy store, first acts on the delay element, which only then transfers the securing element from its secured position to the unsecured position with the set time delay.
  • the mentioned inertia element or the energy store can also work on the clutch element in general and without delay, as is described in detail in the previously referred to prior art according to DE 10 2017 102 549 A1.
  • the mass inertia element (supplementary) ensures that the clutch element is directly transferred from its engaged to the disengaged state.
  • the transition from the secured position of the securing element to its unsecured position and the emergency release or emergency unlocking associated therewith still takes place with a time delay that is unchanged.
  • This variant has an even higher level of crash safety because the event of a crash corresponds directly to the actuating lever chain being interrupted. This is because the inertia element ensures that, in the event of a crash, the clutch element is transferred from its engaged state to its disengaged state. In the disengaged state of the coupling element, the actuating lever chain is mechanically interrupted.
  • the securing element or the locking lever is then transferred into the unlocked or unlocked state.
  • the securing element retains the unlocked or unlocked state even after the crash.
  • the clutch element returns to the engaged position after the end of the crash State back again because the coupling element is spring-biased towards the engaged position.

  • this variant works in such a way that the mass inertia element 11 in turn causes the shaft 10a to rotate as indicated in FIG. 3 via, for example, an interposed gear.

  • the locking lever 6 Since the mass inertia element 11 acts on the locking lever 6 via the delay element 10 with the time delay already described above, the locking lever 6 goes from its locked position V to the unlocked position E after the associated time period.

Since the locking lever 6 has assumed its unlocked position E in the meantime or after the crash, the locking lever 6 then no longer ensures that the coupling element 3 is acted upon in the disengage direction with the aid of the locking lever 6 .

  • the mass inertia element 11 or the associated control lever is deflected. This deflection results in the inertia element 11 releasing the energy storage device 12, which means that it changes from its blocking position B to the release position F. As a result of this, the energy store 12 can act on the delay element 10, which in turn acts on the locking lever 6 after the associated time period, as was previously described in detail.
