Why do seatbelts stop when you pull them hard?

Question

EDIT: I understand that it’s supposed to be for safety. I’m asking because I’ve only experienced the stopping mechanism when I pull. I’ve hit the brakes very abruptly before but nothing. Should I get it looked at?

Answer 1

When you break, you know you’ll break and you most likely “hold” yourself instinctively not to be projected forward. You may not even notice this.

Try sitting in the passenger seat and ask someone else to drive and break abruptly when you least expect it. You’ll notice a different result, if they break abruptly enough.
