Definitions

  • the present invention relates to a security device for a command to open an opening leaf 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 a vehicle leaf are known, provided with a safety device making it possible, in the event of an accident, to avoid the opening of the leaf 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 keeper secured to the body.
  • the bolt is released from the striker by actuating a system known under the generic name of "exterior opening control” or also known under the sign "COE".
  • a system known under the generic name of "exterior opening control” or also known under the sign "COE”.
  • COE anterior opening control
  • Such a system comprises a handle which, when operated in traction by a user, causes the unlocking of the lock.
  • COI internal opening control
  • the stiffness of the return spring of the handle is of course very insufficient to oppose the opening force exerted by the inertial force applied to the handle.
  • a first safety device solution proposed in the state of the art consists of a counterweight device and return spring.
  • the counterweight is mounted on an axis to which the handle is also connected, so as to produce on the axis, during a side impact, an inertial torque contrary to that of the inertial force applied to the handle.
  • This safety device therefore acts by inertia compensation without, however, opposing the normal opening movement of the door because it is in this case slow movements with low acceleration.
  • a user pulls on the handle to open the door it simultaneously drives the counterweight of the safety device, which is then returned to its initial position by the return spring when the user releases the handle.
  • This first solution has the advantage of being relatively inexpensive, but it also has many other disadvantages.
  • the presence of the counterweight increases the size of the exterior opening control system in the thickness of the door and weighs down the vehicle with non-functional masses.
  • this known safety device does not work for very high accelerations due to the inertia of the counterweight.
  • a second security device solution proposed in the prior art is also an inertial solution, but this time operating by blocking the kinematic chain of the exterior opening control.
  • This second known safety device consists of a mass of inertia arranged so as to drive, during a side impact, a member capable of blocking for example the return lever of the kinematic chain thus preventing the release of the bolt from the lock out of the strike.
  • a return spring is present to return the mass of inertia to its rest position.
  • a motor vehicle door opening control comprising a handle pivotally mounted on a base comprising a gripping branch provided at the outer end with an actuating column acting on a transmission assembly.
  • the opening command includes a handle locking member in the event of accelerations caused by an accident and an elastic return member normally holding this member in the non-locking position. of the handle.
  • the locking member comprises a counterweight and two hooks connected to the counterweight and is mounted at the level of the actuation column.
  • the object of the invention is to remedy these drawbacks and to propose an opening control with an inertial safety lock having increased sensitivity to accelerations caused by an accident.
  • the resulting impact accelerates the movable elements of the opening control which results in a movement in a direction opposite to the impact.
  • the moving elements move and can transmit movement to the lock and thus cause the unintended opening of the door.
  • the inertia causes an inertial torque on the handle lever which has the effect of displacing the center of rotation of the inertial member kinematically coupled to the secondary branch of the lever.
  • the inertia of the handle on the inertial member added to the inertia proper of the inertial member causes the latter to rotate.
  • the inertial member then "takes off” from its rest position to immobilize the drive kinematic chain with its blocking element against the base or an element of the kinematic chain.
  • the positioning of the inertial member on a mobile element of the opening control increases the accelerations received by the inertial member which makes it more sensitive, even for low accelerations. It is possible to design this inertial member on board also with a reduced mass and dimensions.
  • the positioning of the inertial member at the level of an internal extension of the main gripping branch on the other side of the handle axis gives it increased reactivity.
  • the lever of the handle exerts on the inertial member a moment of inertia which has the effect of rotating the inertial member in the opposite direction to that of the secondary branch.
  • the inertial member reacts very quickly to the shock so that the inertial member immobilizes the kinematic chain before the handle has even been able to actuate it.
  • the inertial member In real use, in the absence of side impact, the inertial member is in the rest position and the blocking member of the inertial member preferably extends against a lower surface of the secondary branch of the lever or another movable element kinematically connected on the side of the secondary branch.
  • An opening command according to the invention may also include one or more of the following characteristics.
  • the inertial member defines a lower profile which forms an obtuse angle so that the blocking element extends in an oblique direction relative to the main body.
  • the advantage produced by this characteristic is to allow the inertial member by a small angle of rotation to block the kinematic chain.

  • the inertial member comprising a pivot axis to be pivotally mounted on the secondary branch, the pivot axis extends transversely to the predefined direction in an intermediate region located between the main body and the element blocker.

  • the inertial member is mounted movable directly on the secondary branch.
  • the inertial member has a configuration at rest folded against a lower surface of the secondary branch and an active configuration by inertia effect deployed projecting outside the secondary branch. Thanks to the folded configuration, the inertial member does not interfere with the normal operation of the opening control.

  • the main body 32 further comprises a housing 60 for guiding in rotation of a pivot shaft, the guide housing 60 consists of at least half a bearing with a semi-cylindrical recess.
  • a second variant is illustrated by the figures 20 to 24 which differs from the first variant only in that the handle system 14 provides an irreversible blocking of the drive train 100 after activation by inertia.
  • the handle system 14 and the inertial member 30 are returned to their original positions by their respective springs.
  • the secondary branch 20.2 comprises at its free end an elastic blade 62 forming a spring that can be biased along its longitudinal axis in buckling during the pivoting of the inertial member 30.
  • This elastic blade 62 extends in this example axially in end of the secondary branch 20.2.
  • the elastic blade 62 is fixed for example with an anchor pin 64 on the secondary branch 20.2.
  • the elastic blade 62 is made for example from a material such as steel.
  • the inertial member 30 and the elastic blade 62 are provided with complementary hooking means 66 and 68.
  • the complementary hooking means 66 and 68 are able to cooperate by the pivoting of the inertial member 30 to the against the action of its elastic return member.
  • the additional attachment means comprise in particular for example a protruding lug 66 or protrusion on the inertial member 30 and a notch 68 formed at the end of the leaf spring 62.
  • the main gripping branch 20.1 of the handle lever 20 comprises an active part 20.3 of the handle remote from the pivot axis of the handle X1 in the form of a hook which hooks to a return arm 102 to the Bowden cable of the lock 120.
  • One end of the lock strike wire is mounted on the deflection arm 102.
  • the secondary branch 20.2 does not form an element of the kinematic chain 100.
  • the inertial member 30 does not block the movement of the handle lever 20 in pivoting.
  • the inertial member 30 is in a rest position.
  • the inertial member 30 is rotated by its moment of inertia and prevents complete pivoting of the handle lever 20 which prevents actuation of the deflection arm 102.
  • the handle lever 20 comprises an active branch formed by the secondary branch of extension 20.2. This branch 20.2 actuates a deflection arm 102.
  • the inertial member 30 is mounted at the end of the secondary branch 20.2 so that it comes to cooperate by jamming effect on the deflection arm 102 in the event of an impact ( figure 26C ).
  • the inertial member can be mounted mobile on another mobile element than a return lever or a handle lever.
  • the invention is not limited to an inertial member pivotally mounted on a mobile element of the opening control.
  • the inertial member can be slidably mounted on a mobile element of the opening control, for example on the return lever, on the secondary branch or even on another mobile lever of the kinematic chain.
