Definitions

  • the present invention relates to a mechanical actuation unit of a lock for a door of a motor vehicle.
  • locks are mounted, generally, inside a relative door in a position suitable to interact with a lock striker, which is integral with a fixed upright delimiting the door compartment to be closed with said door.
  • the locks comprise a closing mechanism designed to couple in a releasable way with the lock striker to determine closing of the door, and a mechanical actuation unit actuated by an inside handle and by an outside handle of the door to cause release of the closing mechanism from the lock striker respectively from inside the passenger compartment and from outside the vehicle.
  • the mechanical actuation unit comprises a principal inhibiting device, which can be selectively activated from outside the motor vehicle by a key or remote control, or from inside the passenger compartment by means of a knob or by means of the inside handle, to make actuation ineffective on the outside handle to inhibit opening of the door from the outside, thereby producing an external safety function.
  • the mechanical actuation unit has an internal control lever, which is shaped in such as way as to interact with a relay element of the principal inhibiting device to activate and deactivate said principal inhibiting device by rotating respectively in opposite directions.
  • the mechanical actuation unit also comprises an auxiliary inhibiting device, which can be activated selectively to make actuation of the inside handle ineffective and thus inhibit opening of the door from the inside.
  • Actuation of the auxiliary inhibiting device also prevents deactivation of the principal inhibiting device, thus producing an internal safety function (commonly indicated with the name "dead lock") in addition to the external safety function, for the purpose of preventing fraudulent opening of the lock by tools inserted into the passenger compartment from the outside, for example between the window and the body of the door, when the vehicle is left unattended.
  • the elements of the inhibiting devices are subject to unavoidable breakages if the internal control lever is forced to deactivate the principal inhibiting device when the latter is blocked by the auxiliary inhibiting device.
  • the object of the present invention is to produce a mechanical actuation unit of a lock for a door of a motor vehicle, which enables the aforesaid problems to be solved in a simple and inexpensive way and, preferably, enables activation of the principal inhibiting device to be prevented when the door is open.

  • the projection 30 is disposed in a position adjacent to the connecting rods 36, 37 and aligned with the ends 38, 39 along the directions E and F, so that it is possible to control release of the mechanism 8 from the lock striker 3 by operating the levers 62 or 51 respectively by means of the inside or the outside handles of the door.
  • activation of the device 103 from outside the motor vehicle by rotation of the sector 108 causes rotation of the connecting rod 37 about the axis D to divert the trajectory of advance defined by the direction F, so that the opening travel path of the internal control lever 62 and translation of the connecting rod 37 are made ineffective, producing the internal safety function.
  • activation of the device 103 causes blocking of the device 73 by means of engagement of the tooth 107 in the seat 109 and thereby prevents deactivation of the internal safety function from inside the passenger compartment.
  • lever 62 and the end 89 of the lever 79 have a relatively simple shape, are hence relatively simple to produce and to mount and, in particular, are not subject to risks of interference or of disengagement during their movement during activation/deactivation of the device 73.
  • any forcing on the lever 62 merely causes the spring 71 to bend, without the risk of breakages of the components of the unit 1.
  • the configuration of the spring 71 and of the levers 62, 79 enables relatively low overall dimensions and a relatively low number of pieces to be obtained.
  • the presence of the portion 100 designed to cooperate with the projection 30 enables activation of the device 73 to be prevented when the door is open.
  • the lock 2 may be modular, or the unit 1 and the mechanism 8 may be mounted on separate supporting bodies.
  • the lock 2 may be fixed to the upright of the door compartment and interact with a lock striker carried by the door.
  • the unit 1 may be produced without the device 103, or the device 103 may be produced without the tooth 107 and perform a "child safety" function, instead of the "dead lock” function.
  • the movable manual control elements of the levers 62 and 51 may be defined by push-buttons of the door, rather than by handles.
  • the spring 71 may vary in type to and, in particular, the branch 97 may differ in shape from those shown purely by way of example.
