Abstract: The lower bracket assembly for a vehicle steering column includes a lower column support bracket with a central passage. A lower bearing adapter slides into the central passage from the rear. A pair of energy absorption straps engage the column support bracket and the column support bracket and resist further forward movement of the lower bearing adapter. During a collision, the energy absorption straps absorb energy while permitting the lower bearing adapter to move forward and out of the central passage through the column support bracket.

Abstract: An energy absorbing device includes a plastically deformable metal strap for resisting the collapse of a steering column. The strap is initially deformable into one or more V-shaped wave formations by anvils to increase the energy required to advance the strap, thereby increasing the resistance to collapse of the steering column. One of the anvils may be removed to eliminate one of the wave formations and thereby reduce the amount of resistance to collapse of the steering column. Alternatively, the position of an anvil may be varied to vary the shape of a wave configuration from a deep V to a shallow V.

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