  • the arm 12 may be only in contact with the extended portion 56 of the return lever 5 in order to push said return lever 5 to its second position.
  • the electrical actuating device 100 may then rotate back to its initial position, freeing the contact with the return lever 5 and leaving it in its second position maintained by the damper 6. This single contact between the electrical actuating device 100 and the return lever 5 allows the second lever 5 rotating to its second position without the help of the electrical actuating device 100, for example by a push of the second extremity 23 of the handle 2 beyond its activation position.

  • the actuator 11 could stop rotating according to different means.
  • the actuator 11 may for example be connected to an electronic timer stopping the rotation of the actuator 11 when the return lever 5 is in its second position.
  • the actuator 11 may also be configured to measure the current draw in function of the resistance to the rotation. When the return lever 5 is in its second position it stops and the resistance increases due to the second 8 and third 9 levers and its link with the second lever 4. This increase of the resistance of rotation may lead to an increase of the electrical current of the actuator 11 and may generate a signal to stop its rotation in order to avoid stalling of the electric motor.
  • the actuating system may comprise one or both of these two means to determine when the second lever 5 is in its second position.
  • the figures 1a to 10 represent different positions and cinematic steps of the deployment, opening and retractation of the handle 2.
  • figures 1a to 2b are a representation of a rest position where the handle 2 is retracted into the bracket 10 in order to be at the same level of the door body when installed.
  • the first lever 3 is in its rest position and maintained in this rest position by its elastic mean.
  • the second lever 4 is in its rest position and the return lever 5 is in its first position.
  • the return lever 5 is maintained in its first position by its elastic mean.
  • the elastic mean of the return lever 5 is stronger than the elastic mean of the second lever 4 in order that the return lever 5 in its first position maintained the second lever 4 in its rest position.
  • the elastic mean of the return lever 5 is also stronger than the delay element 6 in order to maintain the return lever 5 in its first position.
  • Figures 5a to 6b represent an activation position of the handle 2 where the user activates the handle 2 by pushing the handle 2 into the bracket 10 through a short distance, for example inferior to 5mm, preferably 2mm or 3mm. Due to this push, the first 3 and second 4 levers rotate around their pivot connection 33 and 41 in a direction of rotation opposed to their deployed position. The push of the handle 2 is transmitted on both the first 3 and the second 4 levers due to the parallelogram configuration with the first rod 7. The rotation of the second lever 4 is not transmitted to the return lever 5 due to the contraction of the second rod 8 and the slide of the third rod 9 on its pivot-slide connection 45 between the second lever 4 and the third rod 9. The rotation of the second lever 5 activates the switch 47.
  • the activation of the switch 47 commands the rotation of the electrical actuating device 100.
  • the rotation of the electrical actuating device 100 causes the rotation of the return lever 5 around its pivot connection 55 with the bracket 10 from its first to its second position.
  • the rotation of the first 3 and second 4 levers is made against the torque of their elastic means and the rotation of the return lever 5 is made against the torque of its elastic mean.
  • the electrical actuating device 100 rotates back to its initial position (not represented in figures 5a to 6b ).
  • Figures 7a to 8b represent a deployed position of the handle 2 where the first lever 3 and the second lever 4 have rotated from their activation position to their deployed position, bringing the handle 2 in its deployed position outside the bracket 10.
  • the elastic mean of the second lever 4 allows the passive rotation of the second lever 4 to its deployed position.
  • the rotation of the second lever 4 is transmitted to the first lever 3 by the first rod 7, rotating the first lever 3 to its deployed position.
  • the rotation of the second lever 4 is not transmitted to the return lever 5 by any of the second 8 or third rod 9 which slide with their pivot-slide connections 52, 45.
  • the first lever 3 is maintained in its deployed position due to the first rod 7 which is in abutment with its pivot-slide connection.
  • the return lever 5 is still on its second position due to the delay element 6 or to the resistive torque of the electrical actuating device 100, especially the actuator 11.
  • the third rod 9 is in abutment in order to stop the rotation of the second lever 4 in its deployed position against the torque of its elastic mean.
  • Figures 9 and 10 represent an opening position of the handle 2 where the user can grab the handle 2 and pull it or has taken the handle 2 and pulled it in order to open the vehicle door.
  • the handle 2 rotates around the pivot connection 24 between the second extremity 23 of the handle 2 and the second lever 4.
  • the first extremity 22 of the handle 2 is pulled in an opening position rotating the first lever 3 from its deployed position to its opening position.
  • the rotation of the first lever 3 is not transmitted to the second lever 4 by the first rod 7 due to its pivot-slide connection.
  • the first lever 3 rotates back to its deployed position due to its elastic mean.
  • the return lever 5 rotates from its second to its first position, it also transmits its rotation to the second lever 4 in order to rotate the second lever 4 from its deployed position to its rest position.
  • the third rod 9 is in abutment in order to pull back the second lever 4 in its rest position against the torque of the elastic mean of the second lever4.
  • the rotation of the second lever 4 and the first lever 3 to their rest position are synchronous due to the first rod 7.
  • the handle 2 translates from its deployed position ( figures 7a to 8b ) to its rest position ( figures 1a to 2b ). This translation is slowed down and progressive thanks to the delay element 6.
