What is the purpose of the seatbelt button?

You’ve already gotten into your car, ready to go, when suddenly… you can’t find the seatbelt buckle? You search, you fumble, you sigh. What if the solution was hidden in a detail you see every day without ever paying attention? On the strap, right there, that small, discreet button seems insignificant, almost decorative. Yet, it plays a key role in your comfort and the proper use of the seatbelt. And you’ll see that without it, everything would be much less convenient…
This little button on the belt: what is it really for?
This famous button, sometimes called a seatbelt stopper, is a small plastic piece attached directly to the webbing. It’s usually located under the metal buckle when the seatbelt is at rest. Its role is simple but essential: to prevent the buckle from sliding completely down when the seatbelt retracts.
