Abstract
A protective helmet made from a resilient shell. The shell has a plurality of slits. Each slit has a first end located at a lower edge of the shell and has an adjustable width effective for adjusting the size of the shell. The helmet also has an energy absorbing liner disposed inside the shell. The shell is very stiff to effectively distribute an impact force.

A protective helmet comprising, a resilient shell having an elastic modulus of greater than 400,000 psi and a flexural strength of greater than 400,000 psi, the shell having a plurality of slits, each slit having a first end located at a lower edge of the shell and having an adjustable width effective for adjusting the size of the shell;
- and an energy absorbing liner disposed inside the shell.
A protective helmet comprising, a resilient shell having an elastic modulus of greater than 400,000 psi and a flexural strength of greater than 400,000 psi, the shell having a plurality of slits, each slit having a first end located at a lower edge of the shell and having an adjustable width effective for adjusting the size of the shell, each slit being defined by a pair of edges, the size of the shell being adjustable by bringing the edges of at least one slit closer together by means of a slit adjustment device;
- said slit adjustment device being a compression band assembly having a band, the band having a first end secured to the shell, the band crossing at least one slit and having a second end threadably secured to a fastener, the fastener being held by an anchor, the anchor being secured to the shell;
- an energy absorbing liner disposed inside the shell.
