Finger 27d of the bolt 27 therefore prevents the tilting of the locking rod outside 22 towards its locked outside position when the lock is opened.
  • an external locking lever 30 cooperates with the external locking rod 22.
  • the locking lever outer 30 has a free end 30a intended to be connected to a locking cylinder, for a front door, and one end linked to the outer locking rod 22. This second end is pierced with a circular hole 30b allowing the nesting of the lever external locking 30 on the outside of the crown boss 22a of the external locking rod 22 and, on its underside, a pin (not visible) which engages in a 22nd slot of the connecting rod external locking 22, in an arc centered on the axis of rotation of the latter.
  • the external locking lever 30 bears on its part upper two fins 30d which cooperate with the contactor of detection of the external lockout 10 and the detection switch of the external unlocking 11 by coming into contact with the push buttons 10a and 11a respectively when switching the external locking lever 30 towards its respective positions of exterior condemnation and exterior unlocking.
  • the child locking lever 35 is inserted between base 2 and the pawl 36. As can be seen in figure 14, the locking lever child 35 has at one end a cylindrical axis 35a extending down to cross, the base 2 of the housing 1 through a circular hole 2j drilled in the latter, the retention compartment 7 of the lock, and against the plate 6 by the circular hole 23 drilled therein.
  • the child locking lever 35 can rotate around this axis between its child condemnation and child unlocking positions.
  • the lower end of the cylindrical axis 35a protrudes from the against plate 6 and has a rectangular diametrical slot 35b. In open door position, this end is accessible on the edge of the vehicle door on which the lock is mounted, and allows operate the child locking lever 35, for example using with a screwdriver or key tip, to lock or unlock child the lock.
  • the axis 35a has a radial tab 35f bent towards the high and which abuts against the underside of the base 2 to maintain the axis 35a in the circular hole 2j.
  • the edge of the circular hole 2j has a radial notch 21 of depth slightly less than the extension radial of the radial lug 35f, so as to allow the crossing elastic of this rim by the radial tab 35f during the assembly of the child locking lever 35 on the housing 1.
  • the lever child conviction 35 has a 35c clip inserted on the underside in a slot 2k from base 2 in an arc centered on the hole circular 2d. The clip 35c spans the edge of the slot 2k so as to allow the rotation of the child locking lever 35 but at prohibit its movement parallel to its cylindrical axis 35a.
  • the child locking lever 35 also has a tab bi-stability elastic 35d, the end of which slides along a rim comprising a material bridge 46 carried by the base 2, visible in the figure 5.
  • the tab bi-stability elastic 35d When passing from one side to the other of the material bridge 46, the tab bi-stability elastic 35d is pushed towards the cylindrical axis 35a, so that the two positions of the child locking lever 35 defined by positioning the end of the elastic bi-stability tab 35d are stable. These two positions correspond respectively to the child condemnation and child unlocking of the lock.
  • Child locking lever 35 cooperates with the false pawl 36 and the interior opening lever 33 via the child condemnation link 34.
  • Child condemnation link 34 inserted between the child locking lever 35 and the pawl 36, comprises at a first end a stud 34a extending towards the low and engaged in a 35th circular hole in the locking lever child 35 so as to link this end to the latter in translation circular around the cylindrical axis 35a, and at its other end a nipple 34b extending upward and engaged through the oblong lumen 36h of the false pawl 36 and in the light 33d substantially in L of the interior opening lever 33.
  • Child lock rod 34 forms a disengageable connection between the false-pawl 36 and the internal lever opening 33 during their rotation about their common axis 26.
  • the oblong light 36h ratchet 36 and the radial branch of the light 33d of the interior opening lever 33 allow the sliding of the pin 34b between a position close to the axis 26, visible in the figure 15, in which the child locking rod 34 is said to be disengaged position, and a position distant from axis 26, visible on the Figure 17, in which the child locking rod 34 is said to be engaged position.
  • the rotation of the child locking lever 35 according to arrow R7 in Figure 15 (respectively R8 in Figure 17) therefore allows, by driving the stud 34a, to move the connecting rod condemnation child 34 towards its engaged position (respectively towards its disengaged position).
  • the lock is unlocked child.
  • the stud 34b is engaged in the radial branch of the light 33d of the interior opening lever 33.
  • the lever is actuated interior opening 20, for example by means of a rod connecting the interior door handle to a clip 61 and a branch 62 of the interior opening lever 20, the branch 20b coming to bear on the stop 33f of the interior opening lever 33 to rotate this last towards its opening position of the lock according to arrow R5 of the Figure 18, the stud 34b of the child locking rod 34 comes in abutment against the wall of the oblong light 36h of the false pawl 36 and against the wall of the radial branch of the light 33d of the inner lever opening 33, so that the false pawl 36 is linked in rotation to the interior opening lever 33.
  • the pawl 28 being linked in rotation to the false pawl 36, actuation of the interior opening lever 33 produces the rotation of the pawl 28 in the bolt release position and the opening of the lock.
  • the lock In the disengaged position of the locking rod child 34, as seen in figure 15, the lock is locked child.
  • the nipple 34b is engaged in the branch in an arc of the light 33d of the interior opening lever 33.
  • the interior opening lever 33 When actuated of the interior opening lever 33 to its open position of the lock according to arrow R5 in FIG. 16, the latter slides on the nipple 34b of the child condemnation link 34, without training the latter, which disengages the connection between the interior opening lever 33 and the false ratchet 36 and deactivates the interior opening function of the lock.
  • the tab 36d of the false pawl 36 automatically deactivates the lockout outside of the lock if it was activated. Indeed, when the pawn external locking device 32 is in the disengaged position near the finger 2e, and that the pawl 36 rotates about its axis 26 clockwise towards its opening position of the lock, the edge of the tab 36d comes into contact with the nipple 32c and causes the latter to slide in the radial branch of the light 29c towards the engaged position of the pin of external locking 32.
  • the tab 36d thus makes it possible to carry out the "override" function, ie external unlocking automatic opening inside.
  • the child locking lever 35 carries at one end a external toothed angular sector 35g in an arc centered on the axis 35a, which meshes on a gear train 47 connected to the shaft of the inner locking control motor 9, the gear train 47 possibly comprising only one pinion.
  • Activation of the interior locking control motor 9 in one direction causes the rotation of the child locking lever 35 in its position sentenced child and activation of the engine control inner locking 9 in the other direction causes the rotation of the lever child 35 sentence in its unlocked child position.
  • the lock has a automatic child unlocking during unlocking outside.
  • the child locking lever 35 then carries a tab 48 extending perpendicularly the end of which cooperates with a tab 49 of the outer locking rod 22.
  • the tab 49 is in the vicinity of lug 48.
  • the child locking lever 35 has a cam 50 which comes into contact with the push button 12a of the contactor detection of the child 12 conviction when the lever child condemnation 35 is in its child condemned position.
  • the child conviction detection switch 12 is open when the lock is unlocked as a child, and closed when the lock is condemned child.
  • the circuit internal electric lock is connected via pins electrical contact 15 to a central control unit, capable of control the power supply to the locking control motors exterior 8 and interior condemnation 9 independently one of the other, so as to be able to carry out the function of conviction / external unlocking by activation of the control motor external locking 8, the locking function / child unlocking, by activation of the control motor inner condemnation 9, and the function of super-conviction / desupercondamantion by combined activation of the two motors.
  • this central unit control unit Upon receipt of a super-conviction of the lock, sent for example via a remote control or hands-free access system, this central unit control unit acquires the electrical signal characteristic of the open or closed state of the conviction detection contactor child 12 before carrying out the deadlock, and memorize this signal characteristic throughout the duration of the state of super-conviction of the lock.
  • the central control unit Upon receipt of the next order from unlocking of the lock, for example via a remote control, the central control unit is programmed to activate the interior locking control motor 9 to bring the lock to the child unlocking position only if the memorized signal indicates that the child lock function of the lock was inactive before the execution of the order super-conviction.
  • the two motors 8 and 9 are powered so that they drive their respective links without the legs 48 and 49 coming in contact, because the power of the motor 9 is not sufficient to drive, via lugs 48 and 49, the rotation of the locking rod exterior 22.
  • the unit central does not send power to motor 9, or it supplies it with couple blocked.
