Definitions

  • the present invention relates to a safety device for controlling the opening of an opening such as a door of a motor vehicle. More specifically but not exclusively, the invention applies particularly to the field of securing a motor vehicle against an impact caused by an accident.
  • Handles for vehicle doors are known, equipped with a safety device which, in the event of an accident, prevents the door from opening under the effect of the deceleration undergone by the gripping part of the handle.
  • a lock comprising a bolt secured to the door capable of cooperating with a strike plate secured to the bodywork.
  • the bolt is released from the strike plate by actuating a system known under the generic name of "external opening control” or also known under the sign "COE".
  • a system known under the generic name of "external opening control” or also known under the sign "COE”.
  • COE internal opening control
  • Such a system comprises a handle which, when operated in traction by a user, causes the lock to be unlocked.
  • the stiffness of the handle return spring is of course very insufficient to oppose the opening force exerted by the inertia force applied to the handle.
  • the currently known motor vehicle side handles are equipped with an inertial safety device.
  • This inertial safety device is triggered in the event of a side impact on the door and blocks the opening control to prevent any untimely opening of the side door which could cause the passenger to be ejected from the vehicle.
  • an inertial safety device is composed of an inertial mass and a locking lug or finger secured to the inertial mass, which cooperates with a mobile element of the transmission kinematic chain, generally the transmission or return lever.
  • the locking finger cooperates with said return lever to block it in a position preventing the unlocking of the lock.
  • an inertial safety system comprising two inertial masses, pivotally mounted between a rest position and an active position preventing rotation of the transmission lever, a first of the masses operating reversibly, the second of the masses operating irreversibly.
  • Such an inertial system makes it possible to prevent any untimely opening of the opening in the event of an impact, both for low accelerations and for higher accelerations.
  • the disadvantage of such an inertial system although very effective, is that it is particularly bulky, is not economical and, in addition, has a significant negative impact on the weight of the inertial safety system.
  • the present invention aims to overcome the drawbacks of the prior art by proposing an opening control with an optimized inertial safety system overcoming the aforementioned defects and drawbacks.
  • the invention relates in particular to a control device according to the main claim.

  • the control device combines the advantage of the small size and low weight of a conventional inertial system operating only in a single irreversible or reversible mode with the performance of an inertial system operating in both the reversible and irreversible modes. This effect is obtained by defining a spatial angular offset of two regions of the blocking surface of the inertial member which are different depending on the reversible blocking position in the first angular pivot range or the irreversible blocking position in the second angular range of the inertial member.
  • the blocking surface of the inertial member intercepts the movable element of the kinematic chain in two regions spatially offset from each other, this spatial offset being induced by the different angular pivot ranges of the inertial member respectively in the reversible and irreversible modes.

  • the opening control device 10 provides, in this second embodiment, to block the kinematic chain 100 regardless of 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 stepped 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 a radial stop surface 28 blocking 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 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 blocking elements 44 and secondary 64 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 more secure 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.
  • the inertial member 40 When a user pivots the handle lever 20 in normal operation illustrated in figure 12 , the inertial member 40 is held in its rest configuration by its elastic return member 60 and the terminal 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 into a tilting of small angular amplitude by means of the rocker foot 62 of this inertial member 40. Furthermore, the inner median surface 22 of the handle lever 20 engages 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 strike wire or a linkage known per se.
  • the inertial member 40 In a low to medium amplitude shock, as illustrated in the figures 5 And 6 , the inertial member 40 is rotated by its moment of inertia against the restoring force of its elastic member 60 within the first angular pivot range. As the acceleration undergone is of low to medium intensity, the inertial member 40 comes to abut with its flat lug 48E under the tab 70 without having sufficient inertia to cross the tab 70 and pass over the latter. By pivoting, the inertial member 40 and more particularly its interception surface 46 comes to position itself 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, within the limit of the region Z1 of the interception surface 46.
  • the inertial member 40 has sufficient inertia to pivot until it crosses the tab 70 and reaches the second pivot range.
  • the end-of-travel stop 58 abuts against a relief 59 of the base 12 to limit an angular amplitude of pivoting of the inertial member 40. Since the tab 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 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 comes to cooperate with the circumferential surface 26 of the first notch 25 with the first region Z1 of the surface 46.
  • the blocking element 44 comes to intercept 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 inertial organ 40 operates only in reversible mode and this regardless of 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, such that an untimely movement of the handle lever 20 following an impact can cause the return member 30 to be driven into motion.
  • the secondary branch 20.2 has an end geometry provided with a radial stop surface 28 configured to engage with a radial surface of the blocking element 44 of the inertial member 40 and a circumferential contact surface 24. As previously described, this circumferential surface 24 and this radial stop surface 28 together delimit the second notch 29.
  • the blocking element 44 then becomes embedded, for example, with its wedge-shaped edge 45, inside the relief in a hollow 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 illustrated in the Figures 17 and 18 .
  • the inertial member 40 radially intercepts the movable element without involving the tab 70.
  • the secondary blocking element 64 comes to interpose itself on the trajectory of the return lever 30, also blocking the movement of the latter.
