How do seat belts work? | Skill-Lync

Seat belts have been instrumental in saving countless lives over the years. However, early seat belts were totally different from the current design.

In this video, we have explained the 2-point support system and the current 3 point support system. The key notion of 3 point seat belts is to help the persons to avoid all 3 types of collision.

There is a specific component called retractors which locks the seat belt right when a collision occurs.

There are 3 types of retractors,

Inertia/Non-Locking Retractors - This is a passive system that locks your seatbelts when a collision occurs but does not lock under normal circumstances.

Centrifugal/Emergency Locking System - It is a locking mechanism that uses centrifugal force to lock the seat belt. Hence you can’t pull the seat belt forcefully as centrifugal locks the frame.

Pretensioners - The pretensioner system has a small explosive charge. When a collision occurs, the explosive will also trigger the airbag module pulling the seat belt backwards preventing the passenger from being flung forward.
