Definitions

  • the invention relates to a device for locking a pivotable component of a motor vehicle in a closed position in which the component closes a body opening, in particular for locking a tailgate or a trunk lid, with a Zuziehysvoriques means of which the component from a provisional closed position in a final closed position adjustable and can be locked in this, wherein the device consists of a preferably electrically operable locking device with a pivotable pawl, a cooperating with this lock bracket and the preferably electrically actuated Zuziehtosvorraum.
  • the present invention seeks to provide a device of the generic type in which can be dispensed with electrical installations within the movable component and thus a simple installation of cables and the like necessary components in the solid body structure and not on can be made pivotable component.
  • the invention proposes in principle that the lock bracket is attached to the pivotable component, the locking device is attached to the body in the region of the edge of the body opening and the Zuziehysvorraum is part of the locking device.
  • the pivotable component has as a functional element of the device only the rigid lock bracket. Electrical wiring or other installation is not required in the pivotable component.
  • the locking device including Zuziehysvortechnisch is on the rigid body in the region of the edge of the Body opening attached. Corresponding cables, which are associated with the locking device and / or the Zuziehosvortechnisch or corresponding actuation factors for it are thus laid in the solid body structure, whereby the installation effort is considerably simplified.
  • a simplified construction of the device is achieved by integrating the Zuziehysvortechnisch in the locking device.
  • the locking device itself can be manually operated or actuated by an electric motor.
  • the Zuziehysvortechnisch is electrically operated in each case.
  • the component When the device is used as intended, the component can first be manually or automatically transferred to the closed position when the component is open, with the lock bracket initially engaging in the locking device. Subsequently, the closing device can be adjusted by motor with the Zuziehysvorraum in the end position, whereby the lock bracket further retracted into the body structure and the attached pivoting component can be firmly retracted into the seals of the body openings. To open the component, the Zuziehysvoriques is first moved from the closed position to an open position and subsequently released the lock bracket, so that the manual or automated opening of the component is possible.
  • the closure device has a flat housing which is fastened or attachable to the body, between which mutually parallel housing walls a rotary latch and a rotary lever is rotatably mounted, that the catch two legs and between them an insert gap for having the lock bracket, the housing walls have an open in the direction of the lock bracket engagement gap, the pivot bearing of the catch is disposed on a first side next to a plane which is spanned by the engagement gap and an imaginary extension of the engagement gap along the housing walls, wherein in an open position the catch is positioned with a first leg so that the leg end is seated in the engagement gap, and in a closed position of the insert gap between the legs the engagement gap is directed crossing and the second leg is the Eingriffsspal extends crossing into the housing area, which is arranged beyond the plane, wherein the rotary latch is preferably coupled to a return spring, that on the rotary lever on the one hand, the first end of the pawl is rotatably mounted, the second end in the closed position on the second leg

  • the rotary latch is aligned with the component open in a position in which the first leg of the rotary latch is located in the engagement gap of the housing parts. If the closed position is adjusted by appropriate pivoting of the movable component, then the lock bracket is inserted into the engagement gap and acts on the end of the first leg of the rotary latch, to this around their pivot bearing in to twist a closed position in which the lock bracket engages in the deployment gap of the rotary latch, which is formed between the legs of the rotary latch. The rotary latch is thus rotated, so that its legs is directed substantially crossing the engagement gap of the housing.
