Energy-absorbing device with axial holding for automobile vehicle steering columns |
摘要 |
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.
