Definitions

  • the present invention relates to a handle for doors or the like, and in particular to a lever handle which can be employed for unlocking and simultaneously opening the door of a motor vehicle and is provided with an inertial security device which prevents the accidental opening of this door in the event of an accident.
  • EP-A- 1556569 in the name of the same applicant discloses a handle comprising a lever which can rotate in a frame to be fixed to a door of a vehicle and is mechanically connected to a rocker which can rotate in the frame when the lever is pulled for unlocking the door, said rocker being provided with a shoulder suitable to be intercepted by a stop piece of a locking member comprising a pendulum provided with an inertial mass, so that the stop piece intercepts the shoulder during a strong oscillation of the pendulum caused by inertial thrusts acting on this mass.
  • the handle and thus the door, cannot open accidentally because of the inertial thrusts acting onto the lever during a side impact suffered by the motor vehicle.
  • the locking member of this known handle does not always work in a correct manner, since the pendulum can sometimes go back to its normal position during the impact, for example due to sudden changes of the acceleration acting on the inertial mass, or due to a bouncing of the pendulum. In other words, it is not always possible to synchronize the action of the inertial mass with the movement of the lever and/or to keep the pendulum in the handle locking position for a sufficient time.
  • the handle according to the present invention can be connected to a sensor which changes the shape of the elastic means, i.e. the force which they normally exert on the pendulum, when the sensor detects an acceleration corresponding to the impact suffered by the vehicle. With this arrangement, the handle is always locked during an impact and is automatically unlocked after the impact.
  • the elastic means contract during the impact, so as to exert a force which not only does not oppose but even assists the oscillation of the pendulum, so as to increase the force acting on the locking member.
  • the elastic means made of a shape memory material preferably comprise a helical spring arranged between the pendulum and the frame, so that also the known handles can be easily provided with the device according to the present invention.
  • - figure 1 shows a view in a longitudinal section of the handle in the normal position
  • - figure 2 shows a view sectioned along plane H-II of the handle of figure 1;
  • FIG. 3 shows a view in a longitudinal section of the handle in the impact position
  • figure 4 shows a view sectioned along plane IV-IV of the handle of figure 3.
  • the handle according to the present invention comprises in a known way a frame 1 suitable to be fixed for example behind the outer surface of a door 2 of a motor vehicle.
  • Frame 1 is provided with a transversal pin 3 acting as a fulcrum, around which a shaped extension 4 of a lever 5 suitable for being pulled outwards in the direction of arrow 6 for opening door 2 can rotate.
  • Lever 5 thus rotates around a first axis 7 substantially parallel to the rotation axis of door 2.
  • the other end of lever 5 is provided with an appendix 8 which protrudes into frame 1 and comprises a recess 9 in which a tongue 10 is engaged in a rotating manner.
  • rocker 11 which can rotate in frame 1 around a second axis 12 substantially perpendicular to axis 7.
  • lever 5 is mechanically connected to rocker 11, so that the latter rotates around axis 12 when lever 5 is pulled.
  • a helical spring 13 is arranged in a coaxial manner in rocker 11 for returning it to the original position, together with lever 5, when the latter is not pulled anymore.
  • Rocker 11 is in turn connected to the unlocking mechanism (not shown in the figures) of door 2, so that the latter can be opened by further pulling lever 5.
  • Said connection is for example carried out by means of a cable (not shown in the figures) which is pulled by rocker 11 during its rotation.
  • Rocker 11 is preferably provided with a cam surface 14 on which a tappet 15, arranged at an end of the arm of a locking member comprising in particular a pendulum 16 pivoted to frame 1 or to a body integral therewith, can slide.
  • Pendulum 16 therefore oscillates around a third axis 17 substantially parallel to axis 7 around which lever 5 rotates when rocker 11 rotates around axis 12.
  • the other end of pendulum 16 is provided with an inertial mass 18 which preferably has a flat shape and is arranged close to the centre of frame 1.
  • Rocker 11 is suitably provided with a shoulder 20 arranged at a distance from the cam surface 14 greater than the height of tappet 15 of pendulum 16. Tappet 15 therefore passes under shoulder 20 without contacting it if it slides on the cam surface 14, while it intercepts shoulder 20, so as to act as a stop piece and to prevent the rotation of rocker 11, when it moves away from this surface, in particular due to an oscillation of pendulum 16.
  • rocker 11 rotates in the direction of arrow 21, so that tappet 15 slides on the cam surface 14 without interfering with shoulder 20.
  • the elastic means 19 are made of a shape memory material and are connected through conductors 22 to an acceleration sensor 23 suitable for detecting an acceleration corresponding to an impact of the motor vehicle, in particular an acceleration in a direction substantially perpendicular to door 2. The same acceleration acts also on the inertial mass 18, thereby oscillating pendulum 16.
  • the elastic means 19 modify their shape when they receive a signal from sensor 23, which is preferably arranged in door 2.
  • the signal emitted by sensor 23 is an electric signal which heats the elastic means 19 by Joule effect, so as to activate their shape memory.
  • the elastic means 19 consisting of a helical spring, as in the present embodiment, contract due to said signal, so as to generate a force in an opposite direction with respect to the normal force of the spring, which would tend to expand in the absence of said signal.

Abstract

L'invention concerne une poignée de véhicule comportant un levier (5) qui peut tourner dans un cadre (1) fixé à la portière (2) d'un véhicule et mécaniquement relié à un élément de verrouillage. Ledit verrouillage comporte un pendule (16) doté d'une masse inertielle (18) et monté à pivotement au cadre (1) ou à un corps d'un seul tenant avec ce dernier, de telle sorte qu'une oscillation du pendule (16) peut empêcher la rotation totale du levier (5). Des moyens élastiques (19) exercent normalement sur le pendule (16) une force s'opposant à ladite oscillation ; lesdits moyens élastiques (19) sont faits d'un matériau à mémoire de forme, de telle sorte que leur forme peut changer sur réception d'un signal (25) provenant d'un capteur d'accélération (23).
