    • 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 (β) 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 (β) to the rest position domain (a).
    • 本发明涉及一种用于车门把手的安全装置,特别是为了在侧面碰撞情况下避免所述门的主动打开。 车门手柄防止移动装置,包括: - 阻尼惯性! 系统(17),其围绕位于所述阻尼惯性系统(17)的机械装置(29)与打开机构(9)之间的锁定位置结构域(ß)之间的旋转轴线(A)移动,以防止致动 门把手(1)和休息位置区域(a),其中门把手(1)可以自由地启动; - 弹性装置(21),其构造成使阻尼惯性系统(17)回到其静止位置区域 a)在没有加速的情况下,其中所述阻尼惯性系统(17)包括: - 铰接在所述旋转轴线(A)上的圆柱体(23), - 固定到所述圆柱体(23)的臂(25) 从旋转轴线(A)径向延伸的惯性质量块(27),支撑在所述臂(25)的自由端的惯性质量块(27),其构造成当惯性系(17)由于由侧面引起的加速度引起的惯性力时使惯性系统 车辆的碰撞被施加在所述惯性质量块(27)上,并且阻尼惯性系统(17)进一步包括 旋转阻尼器(37)被构造成使惯性系统(17)从锁定位置域(ß)返回到 休息位置域(a)。
