1. Telescopic Design: The collapsible steering column is made up of several telescoping tubes or segments that fit inside each other. It is typically located between the steering wheel and the dashboard.
2. Collapse Mechanism: Inside the steering column, there's a locking mechanism or a series of spring-loaded pins. These pins are designed to release when a certain amount of force is applied.
3. Impact Detection: When the car experiences a frontal impact, the force of the collision is transferred to the steering column. As the column absorbs this energy, it reaches a predetermined threshold.
4. Pin Release: Once the threshold is reached, the locking mechanism or pins are released, allowing the telescoping tubes to slide smoothly within each other.
5. Controlled Collapse: The steering column begins to collapse, effectively shortening its length. This controlled compression helps reduce the impact force transmitted to the driver's chest, neck, and head.
6. Energy Absorption: The telescoping tubes and the crumple zones of the steering column absorb the energy from the impact, reducing the potential for serious injuries.
7. Driver Protection: By reducing the forward movement of the steering column during a collision, it creates more space between the driver's body and the steering wheel. This helps prevent the driver from sustaining severe chest and abdominal injuries.
8. Safety Features: Collapsible steering columns work in conjunction with other safety features in modern vehicles, such as airbags and seatbelts, to enhance overall occupant protection during accidents.
Overall, the collapsible steering column is a vital safety feature in cars. Its ability to buckle and absorb energy reduces the risk of serious injuries to drivers involved in frontal collisions.
