US Patent 10183689 Steering column apparatus

Disclosed is a steering column apparatus including an impact energy absorbing mechanism for absorbing an impact energy at a secondary collision. The impact energy absorbing mechanism includes an energy absorbing section that serves as a load generating section for absorbing the impact energy. The energy absorbing section includes (a) a resistive member that extends along an axial direction of the middle jacket and is fixed to the middle jacket and (b) a wire having a bent portion that is wound around the resistive member to have a curvature and a front portion that is fixed to the upper jacket, the front portion being at a more forward position than the bent portion.
