Position Head Restraints Properly!

Introduction
  While the number of traffic accident fatalities has been on the decline in recent years, that of injuries has been rising. A significant percentage of this increase is due to the surge of people injured by rear-end collisions.
A driver/passenger of a vehicle struck from behind often sustains a minor cervical injury, which is more commonly known as whiplash. How can we protect ourselves from such injuries?
This issue of ITARDA INFORMATION takes a look at head restraints, which are installed precisely for that purpose, and how to adjust them properly.

1. Rear-end collisions are common

2. Head restraint: protection for vehicle occupants

3. Properly positioned head restraint reduces whiplash risk

4. Case studies


Conclusion

  Rear-end crashes, which account for one-third of all traffic accidents, often cause whiplash injuries in the driver/passenger of the car hit from the rear. The analysis of traffic accident data in Japan clearly shows that a properly positioned head restraint effectively prevents this type of injury.

  The proper position of a head restraint is:
    - High enough so that the head will not tilt over the restraint
    - Forward and as close to the back of the head as possible


  A headrest, as it is called in Japanese, is not a head pillow for comfort, but a safety device that protects the vehicle occupant in the event of a rear-end collision. Remember this. If your car has an adjustable head restraint, adjust it immediately to fit your height!
