What force triggers the helmet shell release system?

• A. 60 lbs
• B. 80 lbs
• C. 100 lbs
• D. 120 lbs

Answer: (B)

A force-activated mechanism is used to release the helmet shell once a substantial load is detected. The trigger value is about 80 pounds of force. This level is chosen to stay secure during normal movement yet disengage quickly in a high-load situation, such as a snag or heavy pull, so the helmet doesn’t stay attached and cause neck injury or prevent the wearer from freeing themselves. If the threshold were much lower, the shell might release too easily during routine activity; if it were much higher, the shell might not release when needed. That’s why 80 pounds is the designed trigger for the helmet shell release system.
