Adjustable energy absorbing device for a collapsible steering column

A collapsible steering column assembly having an outer jacket and an inner jacket movable relative to the outer jacket is disclosed. The assembly includes an energy absorbing device having a support disposed on the outer jacket for supporting a first anvil and a second anvil in relative proximity to each other. An energy absorbing member is secured to the inner jacket and disposed adjacent the first and second anvils for transferring energy from the inner jacket to the first and second anvils during movement of the inner jacket relative to the outer jacket. The second anvil defines a longitudinal axis and includes a first locking member selectively engaging the support with the second anvil movable along the longitudinal axis and rotatable about the longitudinal axis between a plurality of positions for engaging and disengaging the first locking member with the support to facilitate the varied resistance of the second anvil.
