Which safety feature helps in reducing whiplash injuries during a collision?

The head-restraint is designed specifically to reduce the risk of whiplash injuries during a rear-end collision. Whiplash occurs when the head is suddenly jolted backward or forward, causing strain to the neck muscles and ligaments. The head-restraint acts as a support for the head, minimizing excessive movement during an impact and keeping the head closer to the back of the seat. This design helps to absorb some of the forces associated with a collision and reduces the likelihood of neck injury by preventing the head from being thrown back too far. By ensuring that the head is kept aligned with the spine during such events, head-restraints play a crucial role in enhancing occupant safety in vehicles.
