Collapsible steering columns were introduced to reduce the number of serious injuries caused by the impact of the steering column and wheel on the driver’s body in the case of a frontal impact collision whilst driving.
Since the first vehicle was produced, the typical way to steer the vehicle was through a single piece steering column consisting of a long steel rod connecting the steering wheel to the steering gear box. Although this system was effective, it gave little protection to the driver in the case of a frontal impact collision.
Although the first collapsible steering column was invented in 1934, it was never brought to market. However, in recent years, the need for increased safety in vehicles has led to the development of innovative steering columns which collapse on frontal impact for all types of vehicles, including commercial ones.
How does a collapsible steering column work?
The steering column still consists of a long shaft connecting the steering wheel to the steering gear box. In simple terms, the column is comprised of an inner and outer sleeve with a number of bearings contained between each sleeve. On impact, the sleeves will compress much like a telescope. This means that on any frontal collision, the steering column will absorb the energy produced during impact by collapsing.
