The Head Injury Criterion (HIC) - What Does it all Mean?

Generally, experts agree that HIC values above 1000 are life threatening.

Recent crash tests have HIC values as low as 142 (an Audi 8, with airbag, in 1995).

Conclusions:

You cannot hold a child firmly in your arms in a crash
Safety belts save lives
Airbags save heads
Areas under curves and average values have interesting applications.
