What is the round button on the seat belt called?
2 Answers
The round button on the seat belt is called the buckle. Here is an introduction to seat belt-related content: 1. Function: The seat belt functions to restrain movement and provide cushioning, absorbing impact energy and mitigating inertial forces to prevent or reduce the severity of injuries to drivers and passengers. Automotive accident investigations show that wearing a seat belt can reduce fatalities by 57% in frontal collisions, 44% in side collisions, and 80% in rollovers. 2. Principle: When a strong frontal collision occurs, due to inertia, the driver and passengers' bodies move forward rapidly. At this point, the seat belt will exert force to 'pull back' the bodies, absorbing some of the impact energy while the airbag inflates and fully deploys.
I've been driving for many years, and every time I get in the car, I can't do without that round buckle on the seat belt, which we usually call the seat belt buckle. It's the part you insert into the side buckle ring when fastening your seat belt, mainly made of metal, with a round shape that makes it easy to insert and remove. In critical moments, it locks you securely in place, preventing you from being thrown out during a collision. In daily life, I often encounter situations where it gets stuck, such as when dust accumulates and it doesn't work smoothly, requiring regular cleaning and maintenance with a soft cloth. Don't underestimate this little thing—if it fails, the entire seat belt becomes ineffective, which can be dangerous on the highway. I recommend having a mechanic check it during the annual vehicle inspection to avoid major issues caused by minor neglect. Safety devices need to be reliable, and regular checks can prevent accidents.
