<p>An actively variable energy absorber including a convex anvil (32) on a steering column housing, a flat metal strap (36) attached to a steering column support and slidably engaging the convex anvil (32) on an active surface area of the convex anvil (32), and a control apparatus for actively varying the geometric relationship between the flat metal strap (36) and the convex anvil (32) in response to changes in a control variable thereby to adjust the magnitude of the active surface area. Adjusting the magnitude of the active surface area changes the severity of plastic deformation of the flat metal strap (36) and the magnitude of the friction between the flat metal strap (36) and the convex anvil (32) thereby to adjust the force resisting linear translation of the steering column housing.</p> |
