  • the secondary branch 20.2 is provided at the free end with a geometry preventing the inertial member 40 from adopting the irreversible mode when the handle lever 20 is in the ejected position.
  • the opening control device 10 provides, in this second embodiment, to block the kinematic chain 100 whatever the value of the intensity of the shock in the case where the handle lever 20 is in its ejected position, for example when the vehicle is stationary.
  • the geometry of the secondary branch 20.2 defines at the end a stepped or nose profile 27 to delimit the first 25 and second 29 positioning notches configured to cooperate with the blocking element 44 respectively in the flush position and in the ejected position of the handle lever 20.
  • the stepped profile forms for example a projecting nose 27.
  • the second notch 29 is provided with a circumferential contact surface 24 with the interception surface 46 of the inertial member 40, preferably in the region Z2 and with a radial stop surface 28 coming to block the rotation of the inertial member 40 in the reversible mode.
  • the first notch 25 has a circumferential bearing surface 26 with the interception surface 46 of the inertial member 40, preferably in the region Z1.
  • the safety member 40 is identical to the first embodiment as illustrated in figures 3 And 4 .
  • the safety member 40 comprises at least one secondary blocking element 64, here two secondary blocking elements 64A, 64B, the main blocking element 44 cooperating with the secondary branch 20.2 and the secondary blocking element 64 cooperating with the return member 30.
  • the two main blocking elements 44 and secondary 64 are spaced angularly from each other, in order to position themselves simultaneously face to face respectively with an end face of the secondary branch 20.2 and a face of the lever of return 30. The advantage of this arrangement is to ensure safer blocking of the kinematic chain of the opening control 10.
  • the inertial member 40 does not block the movement of the handle lever 20 in pivoting.
  • the inertial member 40 is in a rest position.
  • the handle lever is in a flush position, also known as “flush”.
  • the inertial member 40 When a user rotates the handle lever 20 in normal operation illustrated in Figure 12 , the inertial member 40 is maintained in its rest configuration by its elastic return member 60 and the surface terminal of the handle lever 20 of the secondary branch 20.2 does not intercept the interception surface 46 of the inertial member 40. However, preferably, the secondary branch 20.2 biases the inertial member 40 in a low amplitude tilting angular via the rocker foot 62 of this inertial member 40. Furthermore, the interior median surface 22 of the handle lever 20 engages with the radial fin 34 of the return member 30, driving the latter in pivoting until the lock is unlocked, in this case, by pulling the striker wire or a linkage known per se.
  • the inertial member 40 is driven in rotation by its moment of inertia against the restoring force of its elastic member 60 within the first angular pivoting range.
  • the inertial member 40 abuts with its lug flat 48E under the tongue 70 without having sufficient inertia to cross the tongue 70 and pass over the latter.
  • the inertial member 40 and more particularly its interception surface 46 is positioned on the trajectory of movement of the end of the secondary branch 20.2 and comes into engagement with an end surface of this branch, in the limit of region Z1 of interception surface 46.
  • the inertial member 40 has sufficient inertia to pivot until it crosses the tongue 70 and reaches the second pivoting range.
  • the end stop 58 abuts against a relief 59 of the base 12 to limit an angular amplitude of pivoting of the inertial member 40.
  • the tongue 70 is configured to block the crossing of the inertial member 40 in the opposite direction, the inertial member 40 is maintained in the irreversible operating mode.
  • the interception surface 46 engages with the end surface of the secondary branch 20.2, on the zone Z2 of the interception surface.
  • the blocking element 44 intercepts the secondary branch 20.2 in the first region Z1 of the interception surface 46.
  • the blocking element 44 cooperates with the first notch 25 of the secondary branch 20.2.
  • the interception surface 46 cooperates with the circumferential surface 26 of the first notch 25 with the first region Z1 of the surface 46.
  • the blocking element 44 intercepts the mobile element 20.2, still with the first notch 25, at least partially in the second region Z2 of its interception surface 46, located further downstream than the first region Z1.
  • the inertial member 40 operates only in reversible mode and whatever the value of the intensity of the shock.
  • the secondary branch 20.2 of the handle lever 20 is closer to the return lever 30, so that an untimely movement of the handle lever 20 following an impact can cause the member to move. return 30.
  • the secondary branch 20.2 has an end geometry provided with a radial abutment surface 28 configured to come into engagement with a radial surface of the blocking element 44 of the inertial member 40 and a circumferential contact surface 24. As described previously, this circumferential surface 24 and this radial abutment surface 28 together delimit the second notch 29.
  • the blocking element 44 then fits into place, by example, with its corner edge 45, inside the hollow relief delimited by the projecting nose 27 of the free end of the secondary branch 20.2 of the handle lever 20, in the second notch 29, as this is illustrated on THE figures 17 and 18 .
  • the inertial member 40 radially intercepts the movable element without involving the tongue 70.
  • the secondary blocking element 64 intervenes in the trajectory of the return lever 30, also blocking the movement of the latter.
