Automobile steering column coil energy absorber

摘要

The automobile steering column comprises a steering shaft (1) mounted in a hollow sleeve (2) connected to a support (6) fixed to the chassis (10). The energy absorber consists of a metal coil (5). A movable support (9) is connected to a fixed support (8) integral with the chassis. The movable support is locked on the fixed support with a pre-specified value. The coil is mounted on a rotating sleeve (53) located on a fixed spindle (54). The coil has its end mounted in the movable support connected to the tube so that in the event of shock the movable support can push the double coil and unwind it and absorb the energy.
