Abstract

BACKGROUND:

The American College of Surgeons proposed a method of removing helmets. But the problem with full-face-type helmets is that their shape makes them difficult to remove.

METHODS:

A dummy doll was fixed to a smooth bed surface in the supine position, and a full-face-type helmet with a hook attached to the vertex was placed on the doll's head. A spring balance was attached to the hook, traction was applied to the helmet through the spring balance, and the maximum tension needed to completely remove the helmet was measured.

RESULTS:

A tension of 13.2 +/- 1.8 kg was found. But when cheek pads were removed, the tension required to remove the helmet was 1.7 +/- 0.2 kg.

CONCLUSION:

We devised a full-face-type helmet that uses removable cheek pads so that helmet removal can be performed safely by removing only the cheek pads in the event of an accident.
