Abstract:

A portable helmet is disclosed that provides a level of protection at least comparable to conventional non-portable helmets, with the added function of being quickly portable for storage and transport. The helmet includes a series of interlocking curved wedges that can be rotated along pivot-points located on a center support. Wedges to the front of the center support rotate along a front pivot-point, while wedges to the rear of the center support rotate along a rear pivot-point. The curved wedges rotate to nest under the center support when in the closed position and form a wearable helmet when rotated into the extended position.
