Apparatus and method for retractable steering column

摘要

A retractable steering column is provided. The retractable steering column has a steering column and an outer tube. The outer tube has a first sealing member, and the steering column has a second sealing member. The steering column is sealed in the outer tube using the first and second sealing members. Thus, the first and second sealing members form a cavity between the steering column and the outer housing. The steering column is rotatable with respect to the outer tube and is slideable with respect to the outer tube from a first position to a second position. A gas generator generates a retraction pressure in the cavity to slide the steering column from the first position to the second position.
