Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism consisting essentially of catch and pawl, also with an operating lever mechanism operating on the locking mechanism, and with a locking lever which blocks the locking mechanism at least when acceleration forces of a predetermined magnitude occur, for example in the event of an accident ("crash") wherein the locking lever is elastically coupled to the actuating lever mechanism.
  • a door closing device for motor vehicles which has a jack, one end of which is pivotally connected to an outside handle lever.
  • a counterweight is mounted to generate a force toward the outside of the door in the event of a vehicle collision, in such a way that the outer handle lever performs only a resilient movement.
  • the blocking lever acts on the locking pawl in the direction of its blocking position. Only in the opening normal operation of the locking lever allows the release position of the pawl and thus the locking mechanism. In this way, the reliability is to be increased at the same time simple structure, because the locking lever undergoes a deflection during normal operation of the operating lever mechanism. As a result, each normal actuation and release operation corresponds to the fact that the locking lever is moved and any corrosion, caking, etc. can not occur. That has proven itself.
  • DE 10 2011 010 816 A1 describes a motor vehicle door lock with a locking mechanism of the catch and pawl, working on the locking mechanism operating lever mechanism and a locking lever which blocks the locking mechanism occurring acceleration forces of a predetermined size, for example in an accident ("crash"), and a blocking unit for the locking mechanism.
  • the locking lever is elastically coupled to the operating lever mechanism and controls the blocking unit.
  • the blockade unit interacts with the pawl.
  • the invention enables a motor vehicle door lock, in which, with proper functioning of the mass lock or the locking lever additionally indifferent functional conditions and in particular the so-called "bouncing" can be prevented taking into account a simple structure.
  • the invention enables a motor vehicle door lock, in which, with proper functioning of the mass lock or the locking lever additionally indifferent functional conditions and in particular the so-called "bouncing" can be prevented taking into account a simple structure.
  • the invention relates to a motor vehicle door lock with a locking mechanism consisting essentially of catch and pawl, with an operating lever work operating on the locking mechanism, wherein the actuating lever mechanism has a release lever which is mechanically coupled to the pawl, with a locking lever which at least when the locking occurs Acceleration forces of a predetermined size, for example, blocked in an accident ("crash"), and with a blocking unit for the locking mechanism; which is formed in several parts with blocking lever, transmission lever and clutch lever, wherein the locking lever is elastically coupled to the actuating lever mechanism and controls the blocking unit; wherein the blocking unit interacts with the rotary latch and blocks the rotary latch in the closed state of the locking mechanism.
  • the locking lever in conjunction with the blocking lever ensures that the release lever and consequently the pawl are blocked and that the clutch lever engages the rotary latch.
  • the locking lever thus comes to a multiple and especially two-fold function.
  • the locking lever primarily and as usual ensures that at least in an accident or crash, the locking is blocked.
  • the invention is comparable, as this DE 10 2011 010 815 A1 describes. Because the locking lever is also acted upon or pivoted by the elastic coupling with the operating lever mechanism at each actuation of the operating lever mechanism in normal operation. This ensures that each normal actuation and release operation corresponds to a movement of the locking lever. Any corrosion, caking, etc. can not occur.
  • Actuation lever in normal operation now leads on the intermediate leg spring to the locking lever follows the movements of the external actuating lever or generally the movements of the operating lever mechanism and can follow.
  • the locking lever is transferred from a locking position blocking the position in a locking release position.
  • the locking mechanism spring-assisted
  • the locking lever remains in its locking position due to its inertia. This is true even if the operating lever mechanism or the external operating lever acts on the blocking lever via the already mentioned leg spring. Because the forces acting on the locking lever in the accident inertia forces are significantly larger than the force exerted by the spring on the locking lever spring forces.
  • the locking lever is elastically coupled to the operating lever mechanism, usually with the external operating lever as part of the operating lever mechanism.
  • the locking lever now takes on an additional secondary function to the effect that the locking lever controls the blocking unit for the locking mechanism. That is, depending on the position and movement of the locking lever, the blocking unit is acted upon for the locking accordingly. In fact, the blocking unit may ultimately be transferred by means of the locking lever into a blocking or releasing position.
  • the blockade unit interacts with the catch.
  • the blocking unit and the locking lever are separated from each other.
  • the previously blocked lock is released. That is, in normal operation, the locking lever follows the movements of the actuating lever mechanism via the elastic coupling with the actuating lever mechanism and at the same time the locking lever and the blocking unit are mechanically separated from one another.
  • the previously blocked lock is released in total.
  • the blocking unit and the blocking lever remain engaged with each other. Consequently, the locking mechanism remains in its locked position.
  • the blocking unit is usually formed in several parts with a blocking lever, a transmission lever and a clutch lever.
  • the transmission lever is usually designed as the blocking lever connecting with the clutch lever transfer slider.
  • the blocking lever is in most cases elastically coupled with the transmission lever. For elastic coupling may be provided a prestressed spring or return spring.
  • the blocking lever as part of the blocking unit interacts with the locking lever.
  • the clutch lever is generally engaged with the catch.
  • the clutch lever releases the catch only when the locking lever in conjunction with the blocking lever exits the previously blocked operating lever mechanism.
  • the locking lever in conjunction with the blocking lever jointly ensure that a release lever is blocked as part of the operating lever mechanism.
  • the pawl and the actuating lever mechanism are mechanically connected to each other via at least one coupling element.
  • the pawl is mechanically connected to the previously mentioned release lever as part of the operating lever mechanism via the at least one coupling element.
  • the coupling element may be a foot protruding from the release lever or else a pin which engages in a recess on the pawl.
  • two more or less diametrically opposed feet or pins with respect to a common axis of rotation of the pawl and release lever are realized.
  • the feet or pins may also be formed on an additional plastic part, which is connected to the release lever.
  • the locking mechanism In normal operation and with the locking mechanism engaged (pawl located in the main catch), the locking mechanism is practically blocked twice.
  • the locking lever in conjunction with the blocking lever as part of the blocking unit ensures that the release lever and consequently the pawl mechanically coupled to the release lever are blocked.
  • the clutch lever acts as a further component of the blocking unit on the rotary latch.
  • the locking lever is now according to the invention not only elastically coupled to the operating lever mechanism, but also controls the blocking unit for the locking mechanism.
  • the locking lever from the previous already provides discussed closed position of the locking mechanism respectively the catch that in normal operation not only the operating lever mechanism or the previously blocked by means of the locking lever release lever is released.
  • the locking lever and the blocking unit are also separated from each other. As a result, the blockade unit leaves its previously occupied and the locking or the catch fixing position. This releases the previously blocked lock.
  • the locking lever and the blocking unit or the locking lever and the blocking lever are mechanically separated from each other.
  • the spring connected to the blocking lever and biased spring or return spring for the elastic coupling of the blocking lever with the transmission lever ensure that the transfer slider undergoes a linear application by means of the spring in question. Since the transfer slider is pivotally coupled to the clutch lever, which in turn holds the catch, the released from the locking lever in conjunction with the blocking lever and mechanically coupled to the pawl release lever not only the catch for (spring assisted) opening movements free. But this opening movement of the catch is simultaneously supported by the clutch lever respectively admitted, which in turn is acted upon by the transfer slider accordingly.
  • the locking mechanism In the event of a crash, the locking mechanism remains in its locked position. In this blocked position is in detail the trigger lever or the actuating lever end of the blockade lever, which in turn is held in this position by means of the locking lever. In the event of a crash, the locking lever remains in this position due to the attacking inertial forces, even if the operating lever mechanism or the external operating lever acting on the blocking lever by way of example is deflected. Such deflections lead in resting at rest locking lever only to the fact that the leg spring between the locking lever and the operating lever mechanism respectively the external operating lever in the example undergoes compression.
  • the blocking lever Since the locking lever in the event of a crash, the blocking lever is fixed in its blocking position and thus the release lever and with it the mechanically connected pawl are blocked, the locking mechanism can not open.
  • the blockade unit ensures that in the described Blockade too the catch and with it the locking mechanism are fixed.
  • the blockade unit thus ensures overall that the locking mechanism remains in the closed position or main latching position and, moreover, that the previously mentioned bouncing is prevented.
  • the position of the rotary latch is queried with the help of the blockade unit.
  • the locking lever controls the blocking unit for the locking mechanism. If the locking lever is in the blocking position, the clutch lever additionally ensures that the locking mechanism retains its main locking position. Only when the locking lever is disconnected from the blocking unit in normal operation, the clutch lever releases the then opening catch.
  • the locking lever controls the blocking unit for the locking mechanism. If the locking lever is in the blocking position, the clutch lever additionally ensures that the locking mechanism retains its main locking position. Only when the locking lever is disconnected from the blocking unit in normal operation, the clutch lever releases the then opening catch.

  • the blocking unit 13, 14, 15 interacts with the rotary latch 1 and ensures that the rotary latch 1 and the locking mechanism 1, 2 as a whole in the main locking position undergoes an additional backup.
  • the rotary latch 1 conveyed, for example, during a closing operation of the locking mechanism 1, 2 into the main latching position can not (more) be unintentionally loaded in the opening direction.
