Summary
Removing full-face helmets can be difficult. A new design with removable cheek pads significantly reduces the force needed for safe helmet removal in emergencies.
Area of Science:
- Trauma care
- Emergency medicine
- Helmet safety engineering
Background:
- The American College of Surgeons proposed helmet removal techniques.
- Full-face helmets present unique removal challenges due to their shape.
Purpose of the Study:
- To evaluate the force required for removing standard full-face helmets.
- To develop and test a modified full-face helmet design for easier removal.
Main Methods:
- A full-face helmet was secured to a dummy head in a supine position.
- Traction force was applied via a spring balance attached to the helmet's vertex.
- Maximum tension for complete helmet removal was measured.
Main Results:
- Standard helmet removal required 13.2 +/- 1.8 kg of tension.
- With removable cheek pads, tension decreased significantly to 1.7 +/- 0.2 kg.
Conclusions:
- A novel full-face helmet design incorporates removable cheek pads.
- This modification allows for safer and faster helmet removal in accident scenarios.
