Definitions

  • the invention relates to a motor vehicle door lock with the features of the preamble of claim 1.
  • the well-known motor vehicle door lock from which the invention is based (GB - A - 2nd 193 751), has a one-piece plastic housing in connection with a support plate made of metal, with all function levers of the Locking mechanism via corresponding bearing pins on the carrier plate or on the housing are stored.
  • An otherwise commonly used in motor vehicle door locks, metal end plate opposite the carrier plate (US Pat. No. 4,538, 845) is not provided here, so that this motor vehicle door lock is expensive is quite cheap.
  • motor vehicle door lock is operated purely mechanically, therefore has no actuator.
  • Motor vehicle door locks can, however, with actuators be provided, for example with a pneumatic actuator (DE - C - 42 05 269) or an electric actuator (GB - A - 2 033 954).
  • the invention has for its object to provide how a pneumatic or Electric actuator optimally integrated into the generic motor vehicle door lock can be.
  • the structural optimization of a pneumatic actuator is achieved by that the actuator cylinder, so to speak the outer skin of a pneumatic Actuator forms with the plastic housing in the molding Manufacturing process is made in one piece. For an electric actuator this applies to its actuator housing in a corresponding manner.
  • the motor vehicle door lock shown in Fig. 1 initially, only here indicated, a preferably angular, an inlet slot 1 for a locking block, not shown here, consisting of metal Carrier plate 2 on.
  • a preferably angular, an inlet slot 1 for a locking block not shown here, consisting of metal Carrier plate 2 on.
  • closing elements such as a designed as a rotary latch Lock latch 3 and a pawl 4 rotatably mounted.
  • the metallic bearing elements on the support plate 2 provide the required stability of the Storage, the support plate 2 overall ensures the resistance against high tear forces.
  • 1 and 2 further schematically indicate that a diverse function lever 5, whose function is not important here in detail, has locking mechanism is present.
  • One piece is also provided made of fiber-reinforced plastic, if necessary, in a molding process, especially manufactured by injection molding 6. This is firmly connected to the carrier plate 2, namely by means of Bolt screwed. You can see the openings 7 for the three of the Connection of the carrier plate 2 with the housing 6 and the motor vehicle door lock in total with a motor vehicle door serving bolt in Fig. 2.
  • FIG. 1 and 2 show in connection that the housing 6 without one the end plate arranged facing away from the backing plate 2 2 is made of metal and also all function levers 5 of the locking mechanism primarily on the housing 6, possibly also on or supported by the carrier 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 and for lock latch 3 and pawl 4, the housing 6 to in addition to the support plate 2 single structural element of the motor vehicle door lock overall, it takes on the functions of the existing ones End plate made of metal with. This brings considerable manufacturing technology Advantages and therefore significantly lower costs.
  • the actuator cylinder 8 usually consists of an injection molding process manufactured plastic.
  • the execution of the invention Motor vehicle door lock with a housing 6 that the function of Metal existing end plate with takes over creates the possibility that the actuator cylinder 8 with the housing 6 made of plastic is formed. In any case, this applies to the main part of the actuator cylinder 8, an end plate also made of plastic must of course also here be clipped into the actuator cylinder 8.
  • an electric actuator known as a conventional alternative would be an actuator housing made of plastic corresponding to the housing the door lock can be molded in one piece.
  • the metal end plate is often a has an angularly projecting support arm or is angled at an angle, so as to provide fastening points for function lever 5 of the locking mechanism.
  • Fig. 1 this is now taken into account in that at least one on the housing 6 Angularly protruding support arm 9 is provided, which, preferably, with an actuator 10 of the actuator cooperates.
  • a motor vehicle door lock according to the invention applies that the housing 6 with sockets 11th for plastic bearing mandrels and / or with integrally molded plastic bearing mandrels is provided. Again, some can be less mechanical loaded functional lever 5 itself made as plastic molded parts be. Overall, this results in a further cost optimization Motor vehicle door lock, which nevertheless meets all safety requirements enough.
