ABSTRACT:
The invention provides for a collapsible steering column assembly and method for applying a varying resultant force to resist the collapse of the steering column assembly during an emergency condition. The steering column assembly includes a column jacket adapted to be releasably coupled to the frame for movement along the longitudinal axis L in the emergency condition. The column jacket includes an anvil and is supported by a support bracket. An absorbing strap secured to the supporting bracket is routed around the anvil. The absorbing strap is plastically deformed as the column jacket moves along axis L and an actuator supported by the support bracket applies a force against the absorbing strap. The actuator selectively varies the applied for as the absorbing strap is drawn over the anvil in the emergency condition to optimize the resultant force for the emergency condition.
