Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism consisting essentially of pawl and rotary latch, further comprising a release lever for the locking mechanism, and with at least one actuating lever and a blocking element, wherein the blocking element in normal operation, a mechanical connection and in mechanical operation a mechanical separation between causes the operating lever and the release lever.
  • a blocking lever is provided, which is mounted on an external operating lever.
  • the blocking lever is deflected in accident mode against the force of a spring.
  • the external actuating lever is locked and ultimately causes the desired mechanical separation between the actuating lever or external actuating lever and an associated trigger lever.
  • normal operation corresponds to the fact that no excessive crash-induced accelerations are observed at the motor vehicle door lock in question. That is, in particular, a deflection of the actuating lever is carried out solely and solely in normal operation by applying, for example, an associated handle and mechanically connected to the actuating lever in question handle.
  • the external operating lever in the context of DE 196 24 640 C1 is mechanically connected in this context with an outside door handle.
  • a comparable motor vehicle door lock is described in WO 2012/013182 A2. Also in this case, an actuation of an actuating lever mechanism or of the actuating lever in normal operation ensures that the actuating lever operates directly or indirectly on the release lever, which In turn, usually located in engagement with a catch pawl lifts off the catch. This will open the locking mechanism. As a result, the mostly spring-assisted acted on catch rotates and a previously captured locking pin is released. The same applies to a motor vehicle door equipped with the motor vehicle door lock in question.
  • a locking lever which sets the actuating lever mechanism mechanically inoperative during accident operation.
  • the locking lever is associated with a blocking means which fixes the locking lever in its deflected position. Also in this case it comes - as in DE 196 24 640 C1 - ultimately to a blockage of the operating lever mechanism and consequently the operating lever.
  • the state of the art has basically proven itself when it comes to be able to differentiate between normal operation and accident operation and to effect an effective mechanical separation between the actuating lever and the release lever in accident mode.
  • the known solutions are often characterized by the fact that the operating lever is involved in the sequence of functions.
  • a spring assigned to the actuating lever is often designed to be relatively strong or the actuating forces for the actuating lever during normal operation are high. This is often perceived as disadvantageous for reasons of comfort.
  • the invention is based on the technical problem of further developing such a motor vehicle door lock in such a way that any actuation forces on the actuating lever are reduced during normal operation with an unchanged and functional distinction between normal operation and accident operation.
  • a generic motor vehicle door lock is characterized in the context of the invention in that the blocking element is designed as a clutch lever mounted on the actuating lever, which pivots independently of the actuating lever loaded by spring force during accident operation.
  • the actuating lever is initially not included in the sequence of functions during accident operation or practically not involved. Rather, it comes to an actuation of the actuating lever predominantly in normal operation.
  • the accident operation corresponds to the fact that the operating lever largely remains at rest and pivots only the clutch lever relative to the actuating lever and independently of the actuating lever as a result of the attacking inertial forces.
  • an actuating lever spring assigned to the actuating lever can be made weak by its spring force and typically has a significantly lower spring force compared with the prior art.
  • the actuating lever spring associated with the actuating lever only needs to be equipped with a spring force which ensures that the operating lever is properly returned to its rest position during normal operation.
  • the associated spring force is typically low.
  • the operating lever spring only, for example, together with the operating lever, a connecting means and optionally a end of the connecting means provided handle in normal operation reset.
  • the torques required for this purpose on the actuating lever or on an axis of rotation of the actuating lever are usually low, so that the operating lever spring can be equipped with relatively low spring force compared to the prior art.
  • any operating forces on the actuating lever or the actuating lever acting on the handle are reduced compared to the prior art.
  • main benefits are the main benefits.
  • the clutch lever is generally acted upon by spring force.
  • the clutch lever is typically equipped with its own clutch lever spring.
  • the design is such that the clutch lever pivots against the spring force of the clutch lever spring.
  • the interpretation is usually additionally made so that the clutch lever is formed on both sides pivotable in accident mode relative to the release lever.
  • the clutch lever can be pivoted in accident operation relative to its position in normal operation in two opposite directions, for example, forward / backward or right / left.
  • both positive and negative accelerations are converted into a corresponding movement of the clutch lever.
  • the clutch lever can strike, for example, with positive accelerations on a stop of a housing belonging to the motor vehicle door lock.
  • then may correspond to a movement of the clutch lever due to a negative acceleration to that of Clutch lever pivoted into the void.
  • the reverse can also be done. In both cases, it is ensured that the clutch lever is brought in any accident operation out of engagement with the release lever. Unintentional loading of the release lever, for example, by the still pivoted actuating lever is consequently not possible in accident operation in both cases.
  • the operating lever including the clutch lever mounted thereon, on the one hand, and the release lever, on the other hand are usually arranged at an angle to one another.
  • a right-angled arrangement has proven to be particularly favorable at this point.
  • the actuating lever, including the clutch lever mounted thereon is for the most part arranged in a vehicle transverse direction or X direction.
  • the release lever predominantly has an arrangement in a vehicle longitudinal direction or Y-direction.
  • the vehicle vertical axis direction belongs as well known to the Z direction. In the event of a side impact, corresponding acceleration forces thus act in the X direction and cause the clutch lever to pivot.
  • acceleration forces occurring in accident operation and in a side impact correspond for example to positive acceleration forces to an application in the X direction, whereas negative acceleration forces to belonging to an -X-direction.
  • the clutch lever interacts with a leading edge on the release lever in normal operation.
  • the leading edge on the release lever acted such that the release lever is pivoted about its associated axis of rotation.
  • the pivoting movement of the release lever about its axis of rotation has mostly indirectly or directly with the result that the pawl is lifted as part of the locking mechanism from substantially the pawl and the catch of the catch. In fact, the catch is held in the closed position of the motor vehicle door lock by means of the pawl.
  • the catch can spring-open open and release a previously captured locking pin.
  • the motor vehicle door lock is open.
  • an associated motor vehicle door can also swing open. This corresponds to a normal opening operation in normal operation.
  • the actuating lever remains predominantly at rest, whereas the clutch lever mounted on the actuating lever pivots independently of the actuating lever.
  • the casserole contour on the clutch lever can not (more) interact with the casserole on the trip lever.
  • the release lever and with him the locking mechanism remains at rest and it is expressly not an inadvertent opening of the vehicle door lock.
  • this is generally equipped with a stop element for a connecting means.
  • the connecting means in turn provides for a mechanical coupling of the actuating lever with a handle. If the handle is an external handle, the operating lever is designed as an external operating lever.
  • the connecting means may be a Bowden cable or the like. Also, a rod connection between the respective handle and the actuating lever is encompassed by the invention.
  • the stop element on the actuating lever now ensures the mechanical coupling of the connecting means with the actuating lever. As a result, an actuation of the handle via the connecting means is transmitted to the actuating lever.
  • the operating lever can be pivoted about its axis of rotation.
  • this process corresponds to the casserole contour interacts with the leading edge on the release lever on the clutch lever, so that the release lever is pivoted about its axis of rotation and thereby lifts the pawl of the catch.
  • the abutment element described above on the actuating lever is advantageously also designed as a stop for a spring leg of the actuating lever spring.
  • the operating lever spring is usually a leg spring.
  • the one spring leg of the actuating lever spring is applied to the stop in question, which takes over the described double function as a stop for the spring leg in question and at the same time mechanical coupling element for the connecting means.

  • the plane spanned by the operating lever including the clutch lever mounted on it extends for the most part in the vehicle transverse direction or X-direction, because the actuating lever and the clutch lever are mostly arranged in precisely this vehicle transverse direction.

  • the end of the short L-leg of the L-shaped or vice versa L-shaped actuating lever is the axis of rotation for the clutch lever. Since the clutch lever is largely longitudinally formed, the overall predominantly U-shaped configuration of the operating lever with the clutch lever mounted thereon is explained.

It is also clear from this illustration that the stop element 8a is connected at the end to a long L-leg of the L-shaped or vice-versa L-shaped actuating lever 8.

  • the overall design is such that the operating lever spring 14 is equipped with a larger spring force than that of the clutch lever spring 15 is designed. Overall, however, the spring force built up by the actuating lever spring 14 does not need to withstand the acceleration forces during accident operation. Rather, the operating lever 8 remains in accident mode mostly at rest. In contrast, the blocking element or mounted on the actuating lever 8 clutch lever 12 experiences a pivoting movement due to the attacking inertial forces belonging to the two possible positions beyond the dot-dash line of the clutch lever 12 in normal operation. That is, the clutch lever 12 is formed in accident operation against the release lever 5 on both sides pivotable. The accident mode corresponds to a side impact with corresponding acceleration forces in the X direction.
  • the clutch lever 12 can pivot or swivel in the accident mode relative to the predominantly non-moving actuating lever 8 as shown in FIG. 2, it does not (more) engage the casserole contour 16 on the clutch lever 12 with the casserole edge 17 on the release lever 5. Rather, the casserole contour 16 and the leading edge 17 are disengaged during accident operation. Should there nevertheless be an actuation of the actuating lever 8 in the direction of opening, the coupling lever 12 pivoted into the dashed or solid position ensures that the mechanical connection between the actuating lever 8 and the triggering lever 5 is interrupted in any event during accident operation. The locking mechanism 1, 2 is therefore not applied. Thus, the illustrated motor vehicle door lock can not be opened unintentionally.
