The little button on a car seat belt might not seem like a big deal, but it actually plays an important role in keeping things convenient and safe.
Known as a stop button or retainer button, it’s that tiny plastic piece on the seat belt strap that stops the metal latch plate—the part you click into the buckle—from sliding too far down when you’re not using it.
Imagine if that button wasn’t there. The latch plate would just slide all the way down to the base of the seat belt, making it a pain to grab when you’re ready to buckle up.
Thanks to this simple button, the latch plate stays in an easy-to-reach spot, saving you time and frustration.
