Can the Seat Belt Be Opened When a Car Falls into Water?

[Leroy]

Automobiles have a certain degree of watertight performance. Once a car is submerged in water, the driver's first action should be to immediately unbuckle the seat belt and then quickly unlock the electronic central locking system to prevent the door circuits from malfunctioning. Below is a relevant introduction to car seat belts: Function: Car seat belts are safety devices designed to restrain occupants during a collision and prevent secondary impacts with the steering wheel, dashboard, etc., or to avoid injuries or fatalities caused by being ejected from the vehicle during a collision. Car seat belts, also known as safety harnesses, are a type of occupant restraint system. Working Principle: The retractor's function is to store the webbing and lock it when pulled out, making it the most complex mechanical component in the seat belt system. Inside the retractor is a ratchet mechanism. Under normal circumstances, occupants can pull the webbing freely and evenly while seated. However, when the webbing is continuously pulled out and suddenly stops or when the vehicle encounters an emergency, the ratchet mechanism engages to automatically lock the webbing, preventing it from being pulled out further.
