Abstract

A safety steering column assembly for automobiles, arranged to shorten under the effect of a predetermined force exerted during an impact accident, includes a steering column with a safety sleeve forming a part of the column. The safety sleeve is a grid tube made up of wound laterally spaced grid strands. Each grid strand consists of a plurality of plastics material impregnated fiber strands. The grid strands are located outwardly from and are wound angularly of and around the steering column axis. Adjacent grid strands having the same angular orientation relative to the axis are spaced laterally apart. Further, the grid strands are disposed in crossing relationship.
