Summary: | A steering column assembly for a vehicle includes a housing defining a bore that extends along an axis. The steering column assembly includes a first shaft disposed in the bore and a second shaft telescopically engaged with the first shaft. The second shaft is movable along the axis relative to the housing. A wedge is fixed to the second shaft and is spaced from the housing. During frontal impact of the vehicle, an occupant may impact the steering column assembly. Relative telescopic retraction of the first shaft and the second shaft provides a first stage of energy absorption. As the first shaft and the second shaft telescopically retract, the wedge contacts the housing and deforms the housing in a second stage of energy absorption. |
