Therefore can open the door even with self-locking drives or flap can be opened slightly, or the door jumps under the pressure of the Sealing rubbers on. This ensures that the door opens quickly, if there was a mishap.
  • the locking device according to the invention in a special way for doors, Flaps or hoods of motor vehicles, one use for others Doors, gates or flaps, for example in the field of building technology is conceivable.
  • the arrangement of the movable decoupling element directly on the Driver element or rotary latch offers the advantage of being very space-saving executable locking device that can easily adapt to individual circumstances can be adjusted in terms of space and also with a few additional Sharing gets along.
  • the driver element is rotatably mounted on the pivot axis of the rotary latch.
  • the decoupling element in essential radial direction with respect to the axis of rotation of the catch between its positions are movable.
  • the decoupling element is formed as a bracket, the one in the driving position
  • Driver pin clutched on the rotary latch preferably on the Brackets and / or sliding surfaces in the area of the driver pin on the rotary latch are provided, which are in the disengaged position with a relative rotation the elements to each other a snap back of the bracket behind the driver pin prevent.
  • the last measure excludes that the locking device comes into a position in which the basic functions would no longer be guaranteed.
  • the decoupling element is preferably against the load of a biasing spring movable into its disengaged position so that it is in certain relative positions after disengaging again automatically in its entraining Position returns.
  • the decoupling and opening mechanism is designed so that it has an actuating element that can be triggered manually and / or by motor, the pawl in its open position out of engagement with the rotary latch brings and disengages the decoupling element.
  • actuating element that can be triggered manually and / or by motor
  • pawl in its open position out of engagement with the rotary latch brings and disengages the decoupling element.
  • Such a structure of the decoupling and opening mechanism is in the sense of a simple construction with few parts and small footprint, taking it with regard to this
  • the objective is also preferred to the actuating element and the pawl to mount a common pivot axis rotatably, the pawl against a biasing spring is rotatable relative to the actuating element. Due to the relative rotatability between the actuator and the Rotary trap ensures that the decoupling element is only targeted Actuation of the actuating element can be triggered, so that incorrect positions be avoided.
  • Fig. 1 is a schematic locking device 10 for a tailgate Motor vehicle shown.
  • the locking device 10 has a Rotary trap 12, which is rotatably mounted about a pivot axis 14 and a receptacle 16 has a pin or striker (not shown) for Closing the door can accommodate.
  • the closed position is the Shown locking device 10, in which the rotary latch 12 with the aid of a Pawl 18 is locked.
  • the pawl 18 is about a second pivot axis 20 pivotally mounted, and has a locking lug 22, depending on the rotational position the catch 12 with a main catch 24 on the catch (see FIG. 1 and 6) or a pre-catch 26 (see FIGS. 3 and 4) cooperates.
  • a microswitch 28 detects the closed position of the locking device 10 and is at the illustrated embodiment triggered by the pawl 18.
  • the locking device 10 also has a motor-driven closing aid, which acts on a driver lever 30 which is around the first pivot axis 14 of the catch 12 is pivotally mounted.
  • a driver lever 30 On the driver lever 30 is a bow-shaped decoupling lever 32 rotatable about a pivot axis 34 stored, one designed in the example shown as a torsion spring Preload spring is provided, which strives to sense the decoupling lever to pivot the display counterclockwise.
  • the pivoting ability of the decoupling lever 32 is determined by a driver pin 38 limited, which is arranged on the catch 12 and for example in the closed position shown in FIG. 1 on a contact surface 40 abuts the bow-shaped decoupling lever 32.
  • the decoupling lever is located 32 in this driving position, can be done by pivoting the driving lever 30 the catch 12 are taken, which later will be discussed in more detail.
  • the locking device 10 has a decoupling and opening mechanism, the actuating lever that can be triggered manually and / or by motor 42 which, like the pawl 18, about the second pivot axis 20 is rotatably mounted.
  • the pawl 18 is carried along by the actuating lever 42 takes place via a driver cam 44, which in a recess in the pawl 18 engages a certain relative rotation of the operating lever 42 against the pawl 18 against the load of a second Preload spring 48 allows the torsion spring around the second pivot axis 20 is arranged.
  • On the operating lever 42 there is also an unlocking lever 50 integrally formed with an unlocking pin 52 on the decoupling lever 32 interacts, provided the actuating lever 42 in a corresponding Rotational position is brought.
  • the decoupling lever 32 radially inward against the load of the first To pivot biasing spring 36 and thereby the driver pin 38th and thus to release the catch 12.
  • a sliding element 54 which adapts to the Driver pin 38 connects, acts with a sliding surface 56 on the decoupling lever 32 together and prevents the decoupling element from snapping back 32 with large relative rotation of the driver lever 30 compared the catch 12 with the decoupling lever 32 disengaged.
  • an additional lever 58 is provided, by means of which the pawl 18 can be locked in the disengaged position to prevent that after a Opening and decoupling process when the rotary latch 12 is blocked, for example due to a snow load resting on the tailgate of the vehicle, prevents the pawl from snapping back and thus opening the Tailgate allowed.
  • the locking device 10 is now shown in its open position.
  • the catch 12 is clockwise by a corresponding angular amount twisted in the sense of the illustration and thereby gives the body side assembled pin or striker free.
  • the pawl 18 is located correspondingly in a position releasing the catch 12, the latching lug 22 under the load of a bias spring (not shown) on an outer surface 60 of the catch 12 is present.
