Effect of protective helmet mass on head/neck dynamics
Journal of Biomechanical Engineering
|February 1, 1981
Summary
Crash helmets can worsen whiplash injuries due to added mass. Restraining collars like airbags may mitigate this risk, enhancing head and neck protection during indirect impacts.
Area of Science:
- Biomechanics
- Injury Prevention
- Protective Equipment
Background:
- Crash helmets protect against direct head impacts.
- Helmet mass can exacerbate indirect head impact injuries (e.g., hyperflexion/hyperextension).
Purpose of the Study:
- To examine the potential for crash helmets to contribute to indirect head impact injuries.
- To evaluate the effectiveness of restraining collars in mitigating these risks.
Main Methods:
- Quantitative and qualitative analysis of helmet-induced injury hazards.
- Utilized the UCIN HEAD/NECK computer simulation model for analysis.
Main Results:
- Confirmed that helmet mass can increase hyperflexion/hyperextension injury risk.
- Demonstrated that proposed restraining devices can potentially reduce this hazard.
Conclusions:
- Crash helmets may increase whiplash injury risk.
- Restraining collars show potential for mitigating indirect impact injuries while maintaining direct impact protection.
