Abstract
A steering column assembly. The steering column assembly comprises an upper column member and a lower column member mounted to the upper column member such that the upper column member can move relative to the lower column member. A shock absorption assembly is interconnected between the upper column member and lower column member. The shock absorption assembly includes a piston member and a piston receiver, the piston receiver including absorbing material which, upon impact to the upper column member, is compressed by the piston member within the piston receiver and extruded from the piston receiver so as to absorb impact energy as the upper column member moves relative to the lower column member.
