Everybody knows what happens in an accident if you don’t wear a seatbelt. What you see in this accident looks really painful in slow motion. Modern seatbelts are not just mechanisms which arrest your motion; rather.
They cleverly allow enough movement to minimise internal injuries and help you land safely on an airbag. In this video, we won’t just learn the working of a seatbelt; we will learn why modern seatbelt mechanisms are designed the way they are. So buckle your seatbelt, and let’s start a design journey. Watch the video from Learn Engineering for more info:
When in motion, the driver and passengers are traveling at the same speed as the car. If the driver makes the car suddenly stop or crashes it, the driver and passengers continue at the same speed the car was going before it stopped.
A seatbelt applies an opposing force to the driver and passengers to prevent them from falling out or making contact with the interior of the car (especially preventing contact with, or going through, the windshield). Seatbelts are considered Primary Restraint Systems (PRS), because of their vital role in occupant safety.//wikipedia
