ABSTRACT:
A length adjustable motor vehicle steering column including a tubular first mast jacket element, a tubular second mast jacket element telescopically overlapping the first mast jacket element, a plurality of elastic rolling elements squeezed between linear tracks on the first and second mast jacket elements, a separator having a plurality of cells loosely receiving the elastic rolling elements and maintaining relative spacing therebetween, and a plurality of smaller inelastic rolling elements suspended by the separator between the linear tracks on the first and second mast jacket elements. The elastic rolling elements eliminate lash between the first and second mast jacket elements and support the first mast jacket element on the second mast jacket element for low friction relative linear translation. The inelastic rolling elements define positive stops which limit deformation of the elastic rolling elements and flexure of the steering column perpendicular to the longitudinal centerline thereof.
