Abstract
An apparatus and method of operation dissipates energy associated with the telescopic collapse of preferably two steering column members. The first and second steering column members are moveable relative to one another along a collapse path. At least one anvil is fixed with one of the first and second steering column members. A strap extends along a bent path around the at least one anvil to first and second free ends. The apparatus also includes a lock device operative in a first condition to restrain the first free end with respect to the first steering column member and in a second condition to release the first free end of the strap.
