Definitions

  • the invention relates to a Bowden cable connection arrangement for a motor vehicle lock and / or door module of a motor vehicle lock element arrangement with the features of the preamble of claim 1, a motor vehicle lock or door module according to claim 13, a motor vehicle lock element arrangement according to claim 14 and a method for assembling a motor vehicle lock or door module of a motor vehicle lock element arrangement according to claim 15 ,
  • the Bowden cable connection arrangement in question is used in all types of locking elements of a motor vehicle, such as side doors, tailgates, rear doors, trunk lids, sliding doors, bonnets or the like.
  • the known Bowden cable connection arrangement ( DE 10 2015 105 066 A1 ), from which the invention is based, is assigned to a motor vehicle lock, which in turn is assigned to a sliding door of a motor vehicle.
  • a Bowden cable connection arrangement can also be assigned to a door module, which likewise has a closure element such as a sliding door or the like.
  • a component carrier on which at least one functional component of a locking system, for example a motor vehicle lock, and / or another functional component of the motor vehicle is arranged.
  • the motor vehicle lock interacts with a locking part.
  • the motor vehicle lock can be arranged on the closure element side, that is to say as part of the closure element or door module, and the locking part can be arranged on a body-side counterpart or directly on the motor vehicle body.
  • the locking part is arranged on the closure element side and the motor vehicle lock is arranged on the counterpart or directly on the motor vehicle body.
  • Such a motor vehicle lock is equipped with locking elements such as a lock latch, a pawl, etc., which are each mounted on a lock housing. In a closed position of the lock latch, this interacts with the locking part, which is, for example, a locking bolt, locking wedge, locking bracket or the like. is.
  • the lock latch is usually used locked by the pawl against adjustment in its opening direction.
  • a Bowden cable is provided for the mechanical actuation of the closing elements, which connects, for example, an inside door handle or outside door handle to the pawl.
  • the Bowden cable is coupled to the motor vehicle lock via a Bowden cable connection piece.
  • An actuation of the Bowden cable then allows, for example, the pawl to be lifted out, which means that the lock latch can pivot in the opening direction and thereby releases the locking part.
  • the Bowden cable is fixed to a wall element of the lock housing.
  • the Bowden cable can also be fixed on the component carrier as a wall element.
  • the Bowden cable connector is inserted into a Bowden cable connector receptacle that is recessed at the edge of the wall element.
  • the wall element which is used for coupling the Bowden cable connection piece and for this purpose has the Bowden cable connection piece receptacle on the edge, usually extends in the direction from the outside of the motor vehicle or the outer surface of the closure element to the interior of the motor vehicle or to the inner surface of the closure element, the Bowden cable connection receptacle on the outer edge facing the inside of the motor vehicle of the wall element is provided.
  • an unwanted decoupling of the Bowden cable connection piece and thus of the Bowden cable from the wall element can occur, which can lead to an unwanted opening of the door or to a blocking of the door when the door handle is actuated.
  • the invention is based on the problem of designing and developing the known Bowden cable connection arrangement in such a way that operational safety is increased in the event of a crash.
  • the direction of force is orthogonal to the outer surface or inner surface of the closure element, for example in the event of a side impact on the outer surface of a side door or in the event of a rear impact on the outer surface of a tailgate.
  • the direction of the force action here means in particular the main directional component of the impact force of the impacting object that is orthogonal to the surface mentioned.
  • the wall element which serves to fix the Bowden cable via the Bowden cable connecting piece, also extends in a plane running parallel to this direction of force action or main direction component of the force.
  • the direction of insertion of the Bowden cable connector when it is coupled to the wall element via a Bowden cable connector receptacle provided therein is angled, in particular orthogonally, to the plane along which the wall element extends.
  • the direction of insertion is also angular, in particular orthogonal, to the direction of force in the event of a crash. Since the forces occurring in the event of a crash act transversely to the direction of insertion, unintentional decoupling of the Bowden cable from the wall element against the direction of insertion is reliably prevented.
  • the Bowden cable thus remains functional even in the event of a crash and prevents the door from being opened unintentionally, and also allows the door to be opened using the door handle.
  • the Bowden cable connection piece and the Bowden cable connection piece receptacle interact with one another or are designed in such a way that the Bowden cable connection piece can be inserted or introduced into the Bowden cable connection piece receptacle in an insertion direction, in particular orthogonally, to the plane along which the wall element extends.
  • the Bowden cable connector receptacle is thus shaped in the wall element or has a cross section such that the Bowden cable connector, in particular with a fastening element of the Bowden cable connector provided for this purpose, can be inserted, in particular inserted, at an angle, in particular orthogonally, to the wall element.
  • the direction of insertion is the same direction in which the Bowden cable extends in the area of the Bowden cable connector receptacle, or in which the Bowden cable core is guided in the Bowden cable jacket of the Bowden cable in the area of the Bowden cable connection piece receptacle.
  • the Bowden cable connection piece can be detached from the wall element only against the direction of insertion.
  • releasable is meant a non-destructive decoupling of the Bowden cable and wall element, particularly during regular disassembly.
  • the Bowden cable connection piece receptacle is preferably limited by the material of the wall element, so that there is a positive connection to the respective side or the respective sides. The material surrounds the Bowden cable connector receptacle in particular completely or over most of its circumference (claim 3).
  • Claims 4 to 9 define an embodiment with a gap which connects the Bowden cable connector receptacle, which is otherwise at least predominantly or completely surrounded by material, to the outer edge of the wall element.
  • a gap allows the Bowden cable core to be threaded into the Bowden cable connector receptacle from the side, i.e. parallel to the plane of the wall element, and then to couple the Bowden cable connector with the Bowden cable connector receptacle by an angular, in particular orthogonal, movement.
  • Such lateral threading of the Bowden cable core may be necessary if the Bowden cable end piece, which is coupled, for example, to a locking element, for example a pawl or the like in the interior of the lock, has a cross-sectional shape that does not allow the Bowden cable connector to be passed through the Bowden cable connector receptacle in the insertion direction ,
  • a locking element for example a pawl or the like in the interior of the lock
  • the Bowden cable core applies equally to an optional sealing grommet, in particular a bellows grommet, which serves to surround and seal the Bowden cable core, for example in the interior of the lock.
  • the gap can also be used to thread a corresponding sealing sleeve from the side into the Bowden cable connector receptacle before the Bowden cable connector is then inserted in the direction of insertion Bowden cable connector receptacle is coupled.
  • a corresponding sealing spout extends in particular from the Bowden cable connection piece or its fastening element in the direction of the Bowden cable end piece and, for example, into the interior of the housing.
  • the sealing sleeve is then connected on the one hand to the Bowden cable connection piece and on the other hand to the Bowden cable core. Since the Bowden cable core is guided so that it can move axially in the Bowden cable connection piece and the adjacent Bowden cable jacket, the sealing sleeve must be axially movable in itself, a sleeve in the form of a bellows (bellows sleeve) being particularly suitable for this case.
  • the Bowden cable connector is locked in the Bowden cable connector receptacle.
  • a positive connection is formed in and / or against the insertion direction.
  • the Bowden cable connection piece can have a latching lug or, on two of its opposite sides, a latching lug, which interacts with an undercut on or fixed to the wall element.
  • the Bowden cable connector is rotatably mounted in the Bowden cable connector receptacle, so it cannot be rotated relative to the Bowden cable connector receptacle. Accordingly, the Bowden cable connector is not rotated relative to the Bowden cable connector receptacle during assembly. Rather, it is preferred that the Bowden cable connection piece can be inserted into the Bowden cable connection piece receptacle by a purely linear movement in the insertion direction and - in the end position - can be fixed, in particular locked, in its end position.
  • a motor vehicle lock or door module of a motor vehicle closure element arrangement with a proposed Bowden cable connection arrangement is proposed, the wall element having the Bowden cable connection piece receptacle and / or a further wall element which, in particular, forming a housing cover according to Claim 6, being part of a Lock housing of the motor vehicle lock or a component carrier of the door module.
