Definitions

  • the invention relates to a locking device for motor vehicles with a locking cylinder rotatably arranged from a locking position into an unlocking position.
  • Locking devices of this type are used, for example, to lock and unlock the lock of the tailgate of a vehicle.
  • the lock cylinder is connected via connecting parts to a lever housing which comprises a lock lever which, in the unlocked position, acts on a deflection lever assigned to the lock by pressure on the lock cylinder.
  • a servomotor is usually provided which is attached to the tailgate (housing) and which acts via a coupling part on a central locking lever arranged on the lever housing and this via a sliding movement pivoted from a first to a second end position.
  • a disadvantage of such locking devices which can be actuated via a central locking system is, inter alia, that the coupling part, which is generally made in one piece, must have a complicated shape so that the servomotor can be arranged on the locking device in a space-saving manner.
  • the production of these coupling parts is therefore associated with correspondingly high costs.
  • a relatively large engine stroke is required to perform the required pivoting movement of the central locking lever.
  • the known locking devices have the disadvantage that malfunctions often occur in winter, since sliding parts freeze relatively quickly.
  • FR-A-2 755 911 describes a locking device for motor vehicles in which the central locking function is ensured by means of a rotary motor which engages in a tooth segment via a tooth node.
  • FR-A-2 753 741 describes a linkage device for the automatic control of a child safety device of a knee vehicle for locksmiths.
  • the invention has for its object to provide a locking device of the type mentioned, by means of which both a space-saving arrangement of the servomotor is possible and malfunctions in winter are not to be feared.
  • the invention is essentially based on the idea of connecting the servomotor to the central locking lever via a rotatably mounted pivoting lever, the pivoting movement taking place about a rotational axis fixed to the housing.
  • the connection between the servomotor and the swivel lever is made using a very simple coupling part.
  • 1 denotes a locking device for the tailgate of a motor vehicle, which comprises a locking cylinder 3 which can be rotated by means of a key 2.
  • the locking cylinder 3 is connected to a e.g. made of plastic lever housing 4 rotatably connected.
  • a locking lever 5 is fastened, which acts in a known manner in the unlocking position of the locking cylinder 3 by pressing it in the direction of the arrow denoted by 6 on a bell crank of the vehicle lock, not shown.
  • a central locking lever 7 is also arranged on the lever housing 4 and, according to the invention, is connected to the coupling part 9 of a servomotor 10 via a pivot lever 8.
  • the servomotor is fastened to the door housing or the door frame of the corresponding vehicle door and the pivot lever 8 can be pivoted about an axis of rotation 11 fixed to the housing stored.
  • the pivot lever 8 To connect the pivot lever 8 to the central locking lever 7, the latter has a pin 13 (shown in broken lines in the direction of the longitudinal axis 12 of the locking device 1) which is gripped vertically by two pins 14, 15 arranged on the pivot lever 8.
  • the pivot lever 8 and the coupling part 9 are also pivotally connected to one another via a pin connection, the pin 16 being arranged on the central locking lever 7 and a recess 17 adapted to the pin being arranged in the coupling part 9.
  • the coupling part 9 connected to the servomotor 10 engages in a region of the pivoting lever 8 which lies between the axis of rotation 11 and the end of the pivoting lever 8 facing the central locking lever 7.
  • the pivoting lever 8 is provided with a cam 18 arranged in the region of the axis of rotation 11, which cam is only between two rotary stops 19, 20 which are fixed to the housing and are made of an elastic material can be pivoted.
  • pivot lever can also be used in an advantageous manner with locking devices that are not designed as a pressure lock.
  • the pin 16 can also be arranged on the coupling part.
  • cam 18 provided for limiting the pivoting movement of the pivoting lever from an elastic material and the rotary stops from metal, for example.
