Abstract
The invention provides a steering column assembly for a vehicle. The steering column assembly includes a steering column operable to adjustably support a steering wheel in the vehicle. The steering column is moveable along a path for collapsing movement relative to a vehicle in response to an impact situation. The steering column assembly also includes an energy absorber for dissipating energy associated with the collapsing movement of the steering column along the path. The energy absorber includes an anvil fixedly disposed relative to one of the steering column and the path. The energy absorber also includes a strap drawable over the anvil and substantially fixedly disposed relative to the other of the steering column and the path. The steering column assembly also includes a second strap fixedly disposed relative to one of the steering column and the path for dissipating energy associated with the collapsing movement of the steering column along the path. The steering column assembly also includes at least one quick release bolt engaged with the strap to selectively release the strap relative to the other of the steering column and the path. The at least one quick release bolt e…
