Abstract
The invention provides an energy absorbing apparatus for a steering column. The energy absorbing apparatus includes a first member having a telescoping end and a side wall. The energy absorbing apparatus also includes a second member having a telescoping end and a side wall. The second member is disposed for collapsing telescoping movement with the first member. The energy absorbing apparatus also includes a bushing extending annularly between the first member and the second member. The bushing is fixed to one of the first member and the second member. The energy absorbing apparatus also includes at least one projection integrally formed with the bushing and extending longitudinally and radially along the side wall of the one of the first member and the second member. The at least one projection is spaced from the telescoping end of the other of the first member and the second member for being sheared by the telescoping end of the other of the first member and the second member during the collapsing telescoping movement.
