摘要： A tilt adjustable motor vehicle steering column having a mast jacket on a motor vehicle body structure, a tilt housing supported on the mast jacket for pivotal movement about a lateral centerline of the steering column, a steering wheel rotatably supported on the tilt housing, a tilt latch for immobilizing the tilt housing, and an inertia-actuated secondary restraint operative independent of the tilt latch to prevent upward pivotal movement of the tilt housing. The secondary restraint includes a spool rotatably supported on the mast jacket, a tether on the spool having an end attached to the tilt housing, and an inertia-actuated latch operative to block rotation of the spool in response to high negative acceleration of the motor vehicle. The inertia-actuated latch includes a plurality of radial abutments on the spool, a pawl engageable on the radial abutments, and a pendulum operative to pivot the pawl into engagement on the radial abutments.
摘要翻译：一种倾斜可调的机动车辆转向柱，其具有机动车身结构上的桅杆护套，支撑在桅杆护套上的倾斜壳体，用于围绕转向柱的横向中心线枢转运动;可转动地支撑在倾斜壳体上的方向盘，倾斜用于固定倾斜壳体的闩锁，以及独立于倾斜闩锁操作的惯性致动的次级限制器，以防止倾斜壳体向上的枢转运动。次级约束包括可旋转地支撑在桅杆护套上的线轴，线轴上的系绳具有附接到倾斜壳体的端部，以及惯性致动闩锁，用于响应于机动车辆的高负加速度阻止线轴的旋转。惯性致动的闩锁包括在卷轴上的多个径向邻接件，可接合在径向邻接部上的棘爪，以及可操作以将棘爪枢转成在径向基台上接合的摆锤。

摘要： An energy absorber for a motor vehicle steering column including a yoke pivotable about a lateral centerline of a motor vehicle body and an energy absorbing means between the yoke and the mast jacket responsive to linear translation of the mast jacket relative to the yoke. The mast jacket extends through a bore in the yoke and a plastic bushing in the bore prevents the mast jacket from tilting relative to the yoke before and during linear translation of the mast jacket. The energy absorbing means includes a flat metal strap attached at one end to the mast jacket and bent over a convex anvil on the yoke. The metal strap is pulled over the anvil parallel to a longitudinal centerline of the mast jacket and plastically deformed to convert into work a fraction of the kinetic energy of an impact on the steering column. Because the mast jacket pivots as a unit with the yoke, the metal strap is always parallel to the longitudinal centerline of the mast jacket and the vector force reaction on the mast jacket attributable to the energy absorber intersects the lateral centerline.
摘要翻译：一种用于机动车辆转向柱的能量吸收器，包括可围绕机动车体的横向中心线枢转的轭和响应于桅杆护套相对于轭的线性平移而在轭和桅杆护套之间的能量吸收装置。桅杆护套延伸穿过轭架中的孔，并且孔中的塑料衬套防止桅杆护套在桅杆护套的线性平移之前和之间相对于轭架倾斜。能量吸收装置包括在一端附接到桅杆护套并在轭上的凸砧上弯曲的平坦金属带。将金属带拉过砧座平行于桅杆护套的纵向中心线并塑性变形，以转换为转向柱上冲击动能的一部分。由于桅杆护套作为与轭的单元枢转，金属带总是平行于桅杆护套的纵向中心线，并且由能量吸收器引起的桅杆护套上的矢量力反作用于横向中心线。

摘要： An energy absorber for a motor vehicle steering column including a yoke pivotable about a lateral centerline of a body of the motor vehicle and an energy absorbing mechanism responsive to linear translation of a mast jacket of the steering column relative to the yoke. The mast jacket extends through a bore in the yoke and a plastic bushing in the bore prevents the mast jacket from tipping relative to the yoke. The energy absorbing mechanism includes flat metal strap wound into a spiral coil and cradled or otherwise captured in a flat recess in the yoke tangent to the mast jacket. A distal end of the flat metal strap parallel to the mast jacket is rigidly attached to the latter so that during linear translation of the mast jacket under impact, the distal end is pulled out of the flat recess and unrolls the spiral coil. As the spiral coil unrolls, the flat metal strap is plastically deformed to convert into work a fraction of the kinetic energy of the impact on the steering column.
摘要翻译：一种用于机动车辆转向柱的能量吸收器，包括可围绕机动车辆的车身横向中心线枢转的轭架，以及响应于转向柱的桅杆护套相对于轭架的线性平移的能量吸收机构。桅杆护套延伸穿过轭架中的孔，并且孔中的塑料衬套防止桅杆护套相对于轭架倾斜。能量吸收机构包括缠绕成螺旋线圈的扁平金属带，并且在与桅杆护套相切的轭架中的平坦凹槽中倾斜或以其他方式捕获。平行于桅杆护套的扁平金属带的远端刚性地连接到桅杆护套，使得在桅杆护套在冲击下的线性平移过程中，将远端从平坦凹槽拉出并展开螺旋线圈。当螺旋线圈展开时，平坦的金属带被塑性变形，以将其转化为转向柱上冲击动能的一部分。
