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, wherein the spring and the storage element form a structural unit and are formed as the triggering element acting on the spring lip and wherein the spring lip rests against the triggering element when holding the pawl in the raised position.
  • a so-called memory or memory lever function in motor vehicles is typically realized in the rear motor vehicle door lock, ie 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.
  • there is the danger that the locking mechanism will not open until it reaches the pre-rest position and the rotary latch will re-engage.
  • the associated motor vehicle door lock must be reopened to fully open the tailgate in the example.
  • EP 1 862 618 B1 in that the storage element is held by means of the spring when opening the locking mechanism in contact with at least one lock component. In this way, the overall functional reliability should be increased and a structurally simple design made available.
  • a memory element is provided, which is connected to a housing component.
  • the memory element has a stopper, which with a hook on the pawl interacts to keep them 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.
  • DE 103 61 168 A1 also describes a motor vehicle door lock with a catch of rotary latch and pawl, a trigger element for lifting the pawl and thus opening the locking mechanism and acted upon by a spring storage element, which the pawl as long held in the raised position until the catch is open.
  • the spring and the storage element form a structural unit and are designed as the rotary latch acting on the spring lip.
  • the spring lip is attached to the trigger element.
  • DE 103 61 168 A1 also describes a motor vehicle door lock with a locking mechanism of the catch and pawl, a triggering element for lifting the pawl and thus opening the locking mechanism and acted upon by a spring storage element which holds the pawl in the raised position until the catch is opened.
  • the spring and the storage element form a structural unit and are formed as the pawl acting on spring lip.
  • the spring lip is attached to a fishing camp or a supporting wall of the motor vehicle door lock.
  • EP 0 978 610 A1 also describes a motor vehicle door lock with a catch of catch and pawl, a trigger element for lifting the pawl and thus opening the locking mechanism and acted upon by a spring storage element which holds the pawl in the raised position until the catch is opened.
  • the spring and the storage element form a structural unit and are designed as the rotary latch acting on the spring lip.
  • the spring lip is formed on the triggering element.
  • the invention is based on the technical problem of further developing such a motor vehicle door lock in such a way that compact external dimensions are observed while at the same time a minimum of functional components and associated reduced costs.
  • a generic motor vehicle door lock in the invention is characterized in that the spring lip is connected to a housing or a lock component, that the lock component is a separate partition from the housing in the interior of the housing or is designed as an electronic component carrier that the Rotary latch has an interacting with the spring lip contour, and that the contour in the course of the opening movement of the rotary latch lifts the spring lip of their abutment on the trigger element.
  • the spring lip acts on the trigger element in the transverse direction. ie 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 Gesperreebene, which is typically arranged parallel to the plane defined by the spring lip and the trigger element plane.
  • This initially provides a compact design available.
  • the circumstance contributes to the fact that the pawl and the trigger element are generally coaxially mounted to each other, thus pawl and trigger element are pivotally mounted about the same axis or axis of rotation.
  • the design can be further made so that the triggering element and the spring lip acting on the triggering element can be placed in plan view above the locking mechanism (or also below).
  • the spring lip can also be mounted in overlap with the locking mechanism in a housing.
  • 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 housing or the lock component is generally a plastic component.
  • the spring lip is formed on the housing or the lock component.
  • the spring lip and the housing or the lock component can be designed overall as a one-piece plastic molded part. 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 is a partition wall separate from the housing in the interior of the housing or lock housing.
  • the lock component is alternatively 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 disclosed in US Pat DE 20 2007 005 076 U1 described by the applicant, to which reference is expressly made.
  • the triggering element is advantageously a release 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.
  • 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 a contour interacting with the spring lip. The contour ensures that the catch lifts off the spring lip from its abutment on the trigger element in the course of its opening movement. D.
  • 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.
  • a motor vehicle door lock which first of all manages with a minimum of functional components.
  • 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. In this way, the associated motor vehicle door lock can be particularly compact and slim design.
  • main benefits are the main benefits.
