Abstract
A steering column assembly includes a steering column having an upper steering column tube and a lower steering column tube which are telescopically connected at their lower and upper portions respectively, a stationary bracket fixed to a vehicle body and an energy absorption bracket fixed to the stationary bracket. The energy absorption bracket fixedly receives the upper steering column tube which extends therethrough. The energy absorption bracket gets plastically deformed in response to an impact load exceeding a predetermined value to allow the upper steering column tube to displace downward with respect to the lower steering column tube. The impact load is applied to the energy absorption bracket through the upper steering column tube in the direction along the axis of the steering column. The applied impact load is absorbed through the plastic deformation of the energy absorption bracket.
