    • In an automobile vehicle steering column including a steering shaft mounted in a tube-body by means of bearings and attached to a reinforcing member of the tube-body which is mounted on a support member fixed to the chassis of the vehicle and an adjustment system with an axle for locking the support member, an active retraction device in the steering column comprises two sloping wedges mounted on and having conjugate inclinations relative to the axle, and at least one fusible pin coupling the sloping wedges. The inside sloping wedge is disposed around the depthwise adjustment slide and the outside sloping wedge is attached to the axle of the adjustment system. In the event of an impact, the fusible pin is sheared by the triggering of an air-bag and allows the sloping wedges to move apart and to release the tension in the adjustment system axle in order to allow the steering shaft to move in a required direction.
    • 在一种汽车转向柱中,其包括通过轴承安装在管体中的转向轴,并且安装在安装在固定到车辆的底盘上的支撑构件上的管体的加强构件和具有 用于锁定支撑构件的轴,转向柱中的主动回缩装置包括相对于轴安装并具有共轭倾斜的两个倾斜楔,以及联接倾斜楔的至少一个熔丝。 内部倾斜的楔子设置在深度调节滑块周围,并且外部倾斜楔块附接到调节系统的轴。 在碰撞的情况下,通过触发气囊来剪切熔丝,并允许倾斜的楔形件移开并释放调节系统轴中的张力,以便允许转向轴以所需的方式移动 方向。

    • An energy-absorbing device for an automobile steering column adjustable in depth and/or inclination mounted on a support structure fixed to the vehicle body. The body-tube and steering shaft are clamped and locked in the support structure. A securing device with a rotatable elongate tightening element, such as a bolt or rod, and an operator for rotating the axis of the tightening element clamps the body-tube between coacting clamping elements and vertical sides of the support structure. Provision is made for depth adjustment and inclination of the steering column body-tube by slots in the clamping elements and support structure that allow positioning the tightening element axis at a selected position in accordance with a selected depth and inclination of the body-tube. An energy-absorbing element, in the form of a flat coiled band or a coiled wire, is fixed to an end of the body-tube facing the vehicle steering wheel so that an impact force applied at that end and parallel to the longitudinal axis of the body-tube effects axial translation of the body-tube relative to the support structure. Intermediate toothed elements of the securing device connect the energy-absorbing element to the body-tube and the securing device operator which translates in response to the body-tube translation. If the impact force reaches the value of the tightening or clamping forces, the energy-absorbing element absorbing element absorbs the energy of the impact force as the body-tube translates.
    • 一种用于可调节深度和/或倾斜度的汽车转向柱的能量吸收装置,其安装在固定到车体上的支撑结构上。 体管和转向轴被夹紧并锁定在支撑结构中。 具有可旋转细长紧固元件(例如螺栓或杆)的固定装置以及用于使紧固元件的轴线旋转的操作者将主体管夹在共同夹持元件和支撑结构的垂直侧之间。 通过夹紧元件和支撑结构中的狭槽进行转向柱体管的深度调节和倾斜,允许根据所选择的体管的深度和倾斜将紧固元件轴定位在选定位置。 形式为扁平卷绕带或螺旋线的能量吸收元件被固定到面向车辆方向盘的主体管的端部,使得在该端施加的冲击力平行于纵向轴线 体管相对于支撑结构影响体管的轴向平移。 固定装置的中间齿形元件将能量吸收元件连接到主体管和固定装置操作者,其响应于体管平移而转换。 如果冲击力达到紧固力或夹紧力的值,则能量吸收元件吸收元件吸收体管转换时冲击力的能量。
