Abstract

The invention relates to an handle arrangement comprising a handle, a latch lever for unlatching the door, a deploying system pivotally coupled with the handle, a blocking system comprising an inertial rotor configured to be driven in rotation by an inertial force from a rest position to a preventing position, wherein the blocking system further comprises a bridge moveable about a pivot axis between a disengaged position and an engaged position, wherein the bridge comprises an engagement arm that, in the disengaged position, is spaced apart from the latch lever and, in the engaged position, engages the latch lever to prevent the unlatching of the door, wherein the bridge further comprises an actuating arm configured to cooperate with the inertial rotor when the latter moves from the rest position to the preventing position, such cooperation moving the bridge from the disengaged position and the engaged position.

First claim

The invention claimed is:

1. A handle arrangement comprising:
a handle moveable between a stowed position, a deployed position and an operative position in which the handle causes the unlatch of a door;
a latch lever for unlatching the door;
a deploying system pivotally coupled with the handle and comprising a front lever and a rear lever each cooperating with an end of the handle, the rear lever comprising a first driving member that, in the stowed and deployed positions of the handle, is spaced apart from the latch lever and, in the operative position of the handle, actuates the latch lever to unlatch the door; and
a blocking system comprising an inertial rotor configured to be driven in rotation by an inertial force from a rest position to a preventing position,
wherein the blocking system further comprises a bridge moveable about a pivot axis between a disengaged position and an engaged position, wherein the bridge comprises an engagement arm that, in the disengaged position, is spaced apart from the latch lever and, in the engaged position, engages the latch lever to prevent the unlatching of the door, and
wherein the bridge further comprises an actuating arm configured to cooperate with the inertial rotor when the latter moves from the rest position to the preventing position, such cooperation moving the bridge from the disengaged position and the engaged position.

2. The handle arrangement according to claim 1 , wherein the inertial rotor comprises a second driving member cooperating with the actuating arm of the bridge.

3. The handle arrangement according to claim 2 , wherein the second driving member of the inertial rotor is formed by a curved arm configured to push onto the actuating arm of the bridge when the inertial rotor moves from the rest position to the blocking position.

4. The handle arrangement according to claim 2 , wherein the actuating arm of the bridge comprises a free end with a finger for cooperating with the second driving member of the inertial rotor.

5. The handle arrangement according to claim 1 , wherein the inertial rotor comprises a blocking member configured to engage, in the preventing position, the rear lever and preventing its rotation.

6. The handle arrangement according to claim 1 , wherein the inertial rotor is maintained in the rest position by a reversible deformable member.

7. The handle arrangement according to claim 1 , wherein the pivot axis of the bridge extends in parallel to a double axle mechanism of the rear lever.

8. The handle arrangement according to claim 1 , wherein the bridge is maintained in the disengaging position by a reversible deformable member.

9. The handle arrangement according to claim 1 , wherein bridge comprises a lower end facing the latch lever and an upper end facing the inertial rotor, the actuating arm extending from the upper end and the engagement arm extending from the lower end.

10. The handle arrangement according to claim 1 , wherein the engaging and actuating arms of the bridge extend parallel.

11. The handle arrangement according to claim 1 , wherein the bridge further comprises a counterweight disposed oppositely to the extension of actuating arm.

12. The handle arrangement according to claim 1 , wherein the bridge comprises a hollow cylindrical core about which the bridge pivot and to which extends the engaging and actuating arms.

13. The handle arrangement according to claim 1 , wherein the latch lever comprises a counter-engaging member arranged to cooperate with the engagement arm of the bridge in the engaged position.

14. The handle arrangement according to claim 13 , wherein the counter-engaging member is in form of an open mouth with two stoppers extending in different directions.
