Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism consisting essentially of catch and pawl, further comprising a release element for lifting the pawl and thus open the locking mechanism, and with a spring loaded by a memory element which holds the pawl in the raised position until the Rotary latch is fully or almost completely open.
  • a so-called memory or memory lever function in motor vehicles is typically realized in the rear motor vehicle door lock, that is to say the tailgate lock.
  • the memory lever function is ultimately ensured that the pawl is not inadvertently brought back into engagement with the catch when the locking mechanism is open or can be brought.
  • Such situations are observed in practice, for example, when the tailgate associated with the tailgate lock is not fully opened due to snow load or other burdens or can be opened.
  • a memory element which is connected to a housing component.
  • the storage element has a stopper which interacts with a hook on the pawl to hold it in the open position.
  • a finger attached to the ratchet causes the storage element to be lifted off the pawl. Following this, the pawl slides along the catch and can not enter the pre-rest.
  • a generic motor vehicle door lock in the invention is characterized in that the spring and the storage element form a structural unit and are formed as the triggering element acting on spring lip. Most of the spring lip acts on the trigger element in the transverse direction. That is, the spring lip extends predominantly transversely to the longitudinal extent of the triggering element.
  • the spring lip and the triggering element are arranged substantially in a common plane.
  • the catch and the pawl additionally clamp a Gesperreibene, which is typically arranged parallel to the plane defined by the spring lip and the trigger element plane.
  • the spring and the storage element not only form a structural unit, but are regularly designed in one piece and together define the spring lip.
  • the questionable spring lip is connected to the relevant housing and / or a lock component.
  • the housing or the lock component is generally a plastic component.
  • the spring lip is integrally formed on the housing and / or the lock component.
  • the spring lip and the housing and / or the lock component be designed as a one-piece plastic molding. That is, the housing or the lock component and the spring lip are regularly produced in one go, for example by a plastic injection molding process. As a result, the cost of the spring lip can be set very low.
  • the housing is generally the so-called lock housing.
  • the lock housing regularly acts as a lid, by means of which a locking case storing the lock case is covered and closed.
  • the lock component can be a partition wall separate from the housing in the interior of the housing or lock housing.
  • other lock components typically made of plastic
  • the lock component is designed as a so-called electronic component carrier.
  • Such an electronic component carrier is a plastic plate or else a plastic plate which serves for holding electrical components to be arranged in the interior of the associated motor vehicle door lock, such as, for example, one or more motors, switches, electronic components, etc.
  • An example of an electronic component carrier in motor vehicle door closures is described in DE 20 2007 005 076 U1 of the Applicant, to which reference is expressly made.
  • DE 10 2008 057 478 A1 is mentioned in the name of the applicant.
  • the triggering element is advantageously a triggering lever, which is pivotably mounted in comparison to its axis of rotation.
  • This axis of rotation acts generally at the same time as a rotation axis for the pawl.
  • an actuation of the trigger element or release lever corresponds to the fact that the triggering element or the release lever performs a pivoting movement about the said axis of rotation. at In this process, the trigger element takes the pawl with, if this is to initiate an opening movement of the locking mechanism.
  • the spring lip typically interacts with a formation on the trigger element. Since the spring lip is arranged substantially tangentially to the circular arc-shaped pivoting movement of the triggering element described about its axis of rotation, it is sufficient in this process, when the spring lip engages behind the questionable formation on the trigger element or engages below. This functional position is maintained until the catch moves to its fully or nearly fully open position.
  • the rotary latch has an interacting with the spring lip contour.
  • the contour generally ensures that the catch raises the spring lip of their investment in the triggering element in the course of their opening movement. D. h., As soon as the contour on the rotary latch on the spring lip works, the spring lip is lifted from their investment in the formation of the trigger element, so that subsequently the trigger element and with him the pawl is not (more) held in the raised position or be. This may provide a spring, which acts on the trigger element and with him the pawl in a corresponding sense. Following this, the pawl is against an outer edge of the rotary latch, but can not (more) come into a Vorrastausnaturalung because the catch is open beyond this Vorrastausnaturalung.
  • the spring lip since the spring lip according to an advantageous embodiment of the housing and / or the lock component (made of plastic) is formed, it is recommended that the spring lip performs a substantially vertical deflection movement in comparison to its longitudinal extent. D. h., The spring lip is pivoted perpendicular to its longitudinal extent in order to interact with the formation of the trigger element, as soon as the triggering element in an admission learns the meaning that the pawl is lifted from the catch. Conversely, the spring lip is also deflected perpendicular to the longitudinal extent when the catch with its contour at the opening lifts the spring lip of their contact with the trigger element.
  • the spring lip is formed as formed on the housing or the lock component longitudinal web.
  • the longitudinal web can be equipped on the front with a crosspiece to increase the common contact surface between the formation of the release lever on the one hand and the spring lip on the other.
  • spring and storage element are combined to form a spring lip, which is advantageously a one-piece molding on the housing or lock component of the motor vehicle door lock.
  • the spring lip holds the release element and consequently indirectly the pawl in the raised position until the catch is opened.
  • the spring lip and the trigger element can be arranged in a common plane, moreover still in supervision of (or below) the scaffolding plane in question.
  • the associated motor vehicle door lock can be particularly compact and slim design.

  • the locking mechanism 3, 4 is mounted in a lock case not explicitly shown and spans an associated Gesperreebene.
  • the rotary latch 3 is mounted on an anchored in the lock case bolt 5, which also acts as a rotation axis 5 for the rotary latch 3.
  • For the storage of the pawl 4 is another and anchored in the lock case bolt 6 is available, which defines the axis of rotation 6 for the pawl 4.
  • a trigger element 7 is mounted. That is, the pawl 4 and the trigger element 7 are coaxially mounted with respect to the common axis of rotation 6 in the lock case.
