The invention relates to a safety device for a vehicle door handle, in particular in order to avoid unsolicited opening of said door during a side crash scenario. Vehicle door handle movement prevention device, comprising : - a damped inertia! system ( 17), mobile in rotation around a rotation axis (A) between a locking position domain (ß) in which mechanical means (29) of said damped inertial system ( 17) interfere with an opening mechanism (9) to prevent actuating the door handle ( 1 ), and a rest position domain (a) in which the door handle ( 1 ) can be freely actuated, - elastic means (21 ) configured to bring the damped inertial system (17) back to its rest position domain (a) in absence of acceleration, Wherein the damped inertial system (17) comprises : - a cylindrical body (23) hinged on the rotation axis (A), - an arm (25) fixed to the cylindrical body (23), and extending radially from the rotation axis (A), - an inertial mass (27) supported at the free end of said arm (25), configured to bring the inertial system (17) in locking position when inertial forces due to accelerations caused by a side crash of the vehicle are applied on said inertial mass (27), and in that the damped inertial system (17) further comprises a rotational damper (37) integrated in the cylindrical body (23) around rotation axis (A), the rotational damper (37) being configured to temporize the return of the inertial system ( 17) from the locking position domain (ß) to the rest position domain (a). |
