Buckle Crunch — Europe vs. North America
Buckle crunch is not a candy bar. It’s a situation where the vehicle seat belt’s buckle is pulled up into the belt path of a car seat. Instead of the seat belt webbing doing all the work of restraining the car seat, the hard plastic of the buckle is pulled inside the belt path. This makes for an insecure installation because the plastic of the buckle can shatter or the car seat can shift along the plastic portion of the buckle instead of being held back by the webbing.
