Abstract

A steering column assembly for a vehicle comprises a column jacket and an energy absorption system. The column jacket is configured to undergo a collapse event involving a translation of the column jacket along a longitudinal axis in response to application of a column compression force following the occurrence of a predefined event. The energy absorption system includes an anvil coupled to the vehicle and a strap coupled to the column jacket with the strap extending through the anvil such that the strap is drawn over the anvil in response to the collapse event. The strap is configured to cause a deformation force to be created between the strap and the anvil so as to resist relative movement between the strap and the anvil during the collapse event. The strap is configured such that the deformation force varies along the length of the strap.
