  • the main blocking element 44 preferably has bilateral operation and extends in the plane of symmetry.
  • the main blocking element 44 preferably has an orifice 43 capable of receiving the pivot rod 47 of the inertial member 44.
  • the elastic member 60 comprises two springs 60A, 60B mounted on either side 'other of the blocking element 44 around said rod 47. These two springs 60A, 60B can be connected together or not, for example.
  • 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 impact 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 step or nose profile 27 to delimit 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 abutment surface 28 which blocks 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 figure 3 And 4 .
  • the organ of safety 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 44 and secondary 64 blocking elements are angularly spaced from each other, in order to be positioned simultaneously face to face respectively with an end face of the secondary branch 20.2 and a face of the return lever 30.
  • the advantage of this arrangement is to ensure a 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 called "flush”.
  • the inertial member 40 When a user pivots 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 end surface 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 urges the inertial member 40 in a tilting of small angular amplitude via the rocker foot 62 of this inertial member 40. Furthermore, the inner median surface 22 of the lever handle 20 comes into engagement with the radial fin 34 of the return member 30, causing the latter to pivot until the lock is unlocked, in this case, by pulling the striker wire or a known linkage in itself.
  • the inertial member 40 In a low to medium amplitude shock, as shown in the figure 5 And 6 , 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 range of pivoting. Like the acceleration undergone is of low to medium intensity, the inertial member 40 abuts its lug flat 48E under the tongue 70 without having enough inertia to cross the tongue 70 and pass over the latter. By pivoting, the inertial member 40 and more particularly its interception surface 46 is positioned on the displacement path of the end of the secondary branch 20.2 and comes into engagement with an end surface of this branch, in the boundary of region Z1 of intercept surface 46.
  • the inertial member 40 has enough inertia to pivot until it crosses the tongue 70 and reaches the second pivot range.
  • the limit stop 58 comes into abutment 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 comes into engagement with the end surface of the secondary branch 20.2, on the zone Z2 of the interception surface.
  • the blocking element 44 comes to intercept in the first region Z1 of the interception surface 46 the secondary branch 20.2.
  • 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 element mobile 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 operation is substantially different when the handle lever 20 is in an ejected initial position, as may occur in certain situations, in particular when the vehicle is stationary. This is illustrated in figures 17 and 18 .
  • the inertial member 40 operates only in reversible mode, regardless of the value of the intensity of the impact.
  • 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 a shock can cause the drive member to move. reference 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 of 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 comes to fit, for 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 shown in the figures 17 and 18 .
  • the inertial member 40 radially intercepts the movable element without involving the tongue 70.
  • the secondary blocking element 64 is interposed on the trajectory of the return lever 30, also blocking the movement of the latter.
