Dynamic Testing of the Strength of Helmet Chin Straps
View through CrossRef
Abstract
A dynamic test of-chin strap strength was introduced into the British Standard BS 2495 in 1980. This test has subsequently been adapted for bicycle and horse riding helmets without the same correlation between accident and test failures being established. The causes of force peaks and oscillations in the test traces have been identified, and a means was found of obtaining reliable chin strap force measurements. Recommendations are made for improving the test so that chain straps and buckles are adequately strong but not over-designed.
