More and more automakers are recognizing the importance of “active head restraints” in preventing spinal/neck injuries and damages resulting from whiplash. New 2006 models from Honda and Mercedes Benz now feature restraint systems. This is a response to the growing demand for anti-whiplash safety equipments. Whiplash is the result of impulsive stretching of the spine, often the result of a rear-end collision between cars or trucks. The consequences of whiplash range from mild pain for a few days, to severe disability caused by restricted head movement and persistent pain.

The Insurance Institute for Highway Safety estimates that a total of $8.5 Billion are paid in whiplash claims annually. However, the frequency and depth of the claims are lower in states with laws limiting whiplash tests. The IIHS has also initiated an award and test for whiplash in 2005, bringing more focus to the issue. It’s “Top Safety Pick” award is based on combined scores that includes results for the whiplash test. Automakers are compelled redesign seats and headrests to address these tests.
