ABSTRACT:
An energy-absorbing motor vehicle steering column including a structural housing, a releasable attachment between a body of the motor vehicle and a forward end of the structural housing, and a releasable attachment between an aft end of the structural housing and the vehicle body which restrains the aft end vertically and in the direction of a longitudinal centerline of the structural housing. The aft attachment includes a lateral rod on the vehicle body, a retainer on the structural housing which hooks over the lateral rod, a pair of blocks on the structural housing slidable in the direction of the longitudinal centerline of the latter, each having a ramp facing the lateral rod, and a pair of springs biasing the blocks toward the aft end of the structural housing. The springs wedge the ramps on the blocks under the lateral rod. Vector components of the force reactions between the blocks and the lateral rod perpendicular to and in the direction of the longitudinal centerline of the structural housing eliminate lash between the aft end of the structural housing and the vehicle body in the same directions.
