<p>An energy absorbing device for a collapsible steering column (24) of a vehicle includes an M-shaped plastically deformable strap (12) for imposing a resistance to collapse of the steering column (24) when the steering column (24)collapses in a vehicle a collision. An anvil (18) adjusts the resistance to collapse imposed on the steering column (24) by the strap (12). A controller (56) produces a signal of a magnitude indicative of an amount of resistance needed to be imposed on the steering column (24) by the strap (12) to better protect from injury a driver seated behind the steering column (24) at the time of the collision. An actuator (54) receives the signal and actuates the anvil (18) to adjust the amount of resistance imposed by the strap (12) in accordance with the magnitude of the signal.</p> |
