What is the primary function of Active or Intelligent Head Restraints?

The primary function of Active or Intelligent Head Restraints is to reduce neck injuries from rear-end collisions. These systems are designed to move forward in the event of a crash to better support the occupant's head and neck. By doing so, they help decrease the distance that the head travels backward during a collision, which can significantly mitigate the force exerted on the neck and help prevent injuries such as whiplash.

While head restraints may also provide a degree of comfort and support during driving, their foremost purpose is safety in the event of a collision. The active design responds reactively to movement and impact, ensuring that the back of the head is supported immediately, adapting to the dynamics of the crash. This makes them a vital component of modern vehicle safety systems, particularly in rear-end accidents.
