GENERAL KNOWLEDGE

Detailed explanation-1: -A pretensioner is designed to retract some of the webbing of a seatbelt the instant a collision occurs, tightening the seatbelt to restrain occupants quickly and reducing the amount they are thrown forward in a moderate or severe frontal crash. Load limiters help protect occupants from seatbelt-inflicted injury.

Detailed explanation-2: -Although almost all new vehicles have this up front, based on our tally of 2022 model-year vehicles from the SaferCar database maintained by the National Highway Traffic Safety Administration, only about 51 percent of mainstream models have pretensioners and load limiters in the back seat.
