Definitions

  • the invention relates to a motor vehicle door lock with a preferably angular, an inlet slot for a locking block, consisting of metal support plate, locking elements mounted on the support plate, such as a lock latch and pawl and a locking mechanism having various functional levers, and with an integral piece of fiber-reinforced plastic, if necessary, in one Manufacturing process manufactured, firmly connected to the support plate, in particular screwed housing.
  • the known motor vehicle door lock from which the invention is based (US Pat. No. 4,538,845) has a housing which is produced in one piece from plastic by injection molding and which is closed on the rear side facing away from the carrier plate with an end plate made of metal.
  • the housing forms a central, with some openings provided supporting wall, on one side in corresponding receptacles and with the formation of a catch bearing for the locking block the lock latch and the pawl are arranged, while on the other side bearing sleeves or bearing pins are formed, one Wear a series of function levers for storage purposes. Individual function levers are even made of plastic in a molding process.
  • the housing is designed without an end plate arranged on the rear side facing away from the carrier plate and also all the function levers of the locking mechanism are primarily on Housing, possibly also on or supported by the support plate. According to the metal end plate is completely eliminated, the bearings of all function levers are primarily relocated to the housing. Possibly. the bearings of the function levers are supported by formations on the carrier plate or connecting plates to the carrier plate.
  • the motor vehicle door lock known in the prior art can of course be provided with a pneumatic actuator known per se (DE - C - 42 05 269).
  • the motor vehicle door lock according to the invention is particularly cost-effective in that the actuator cylinder of the pneumatic actuator is now formed in one piece with the housing in plastic. This is a special feature of the solution according to the invention, which has become possible by eliminating the metal end plate.
  • the metal end plate in the motor vehicle door lock known from the prior art has at least one support arm which protrudes at an angle from a plane parallel to the plane containing the inlet slot. More precisely, the metal end plate of the prior art is bent at a corresponding angle.
  • a corresponding design is realized in a special embodiment of the invention in that at least one angularly projecting support arm is provided on the housing. This can, preferably, cooperate with an actuator of the actuator.
  • the housing is provided with sockets for plastic bearing mandrels and / or with integrally molded plastic bearing mandrels.
  • the motor vehicle door lock shown in FIG. 1 initially has, preferably only hinted at here, a carrier plate 2, preferably made of metal, which has an inlet slot 1 for a locking block, not shown here.
  • a carrier plate 2 preferably made of metal, which has an inlet slot 1 for a locking block, not shown here.
  • locking elements such as a lock latch 3 designed as a rotary latch and a pawl 4 are rotatably mounted.
  • the metallic bearing elements on the carrier plate 2 offer the required stability of the bearing, the carrier plate 2 as a whole ensures the resistance to high tearing forces.
  • a diverse function lever 5 the function of which is not important here in detail, has a locking mechanism.
  • a housing 6 which is made in one piece from fiber-reinforced plastic, if appropriate, in a molding process, in particular by injection molding. This is firmly connected to the carrier plate 2, namely screwed by means of screw bolts.
  • the openings 7 for the three screw bolts serving to connect the carrier plate 2 to the housing 6 and the motor vehicle door lock with a motor vehicle door can be seen in FIG. 2.
  • housing 6 is made without a metal end plate 2 arranged on the rear side facing away from the carrier plate 2 and also all the function levers 5 of the locking mechanism primarily on the housing 6, possibly also on or supported by the support plate 2 are stored. While maintaining the one-piece made of plastic Housing 6 as storage for the function lever 5 of the locking mechanism as well as for lock latch 3 and pawl 4, the housing 6 becomes the only structural element of the motor vehicle door lock as a whole in addition to the carrier plate 2, thus assuming the functions of the metal end plate previously available. This brings considerable advantages in terms of production technology and thus significantly lower costs.
  • the actuator cylinder 8 usually consists of a plastic produced by injection molding.
  • an actuator housing made of plastic would correspondingly be integrally formed with the housing of the door lock.
  • the end plate which is made of metal, often has an angularly projecting support arm or is angled at an angle, so as to provide fastening points for function levers 5 of the locking mechanism.
  • FIG. 1 this is now taken into account by the fact that at least one angularly projecting support arm 9 is provided on the housing 6, which preferably interacts with an actuating element 10 of the actuator.
  • the housing 6 is provided with sockets 11 for plastic bearing pins and / or with integrally molded plastic bearing pins. Again, some can be less mechanical loaded functional lever 5 itself be made as plastic molded parts. Overall, this results in a motor vehicle door lock which is further optimized in terms of cost and which nevertheless satisfies all safety requirements.
