## Abstract

A protective helmet, particularly used by children, is provided to include an enclosed, generally cylindrical helmet structure providing a plurality of layers of first and second density polymeric foam respectively, with a chin panel mounted to a first side of the helmet arranged for securement to a second side of the helmet.

## Claims

### Claim 1

A protective helmet, comprising,
a helmet body, having a cylindrical configuration including an outer rigid wall, with a polymeric foam first layer coextensive within the wall, with the first layer having a first density, and
a polymeric foam second layer having a second density less than said first density coextensive with the first layer, and
an inner flexible fibrous web mounted to the second layer, with the web positioned about a helmet cavity, with a plurality of ear openings directed through the helmet cavity on opposed sides of the helmet cavity, a facial opening directed through the outer wall in communication with the helmet cavity, with an elastomeric skirt projecting from the outer wall about the neck opening, and
a chin panel mounted between the facial opening and the neck opening, with the chin panel selectively mounted relative to the other wall, with the chin panel including a chin panel strap, a buckle mounted to the outer wall for securement to the chin panel strap, and
a reinforcing strap, having reinforcing strap connectors at opposed distal ends of the reinforcing strap and second connectors mounted to the outer wall, with an individual of said second connectors mounted adjacent to an individual of said ear openings, and
the first layer includes a plurality of first dye capsules having a first fluid dye of a layer, and a plurality of first conduits, each of said first conduits in communication with an individual one of said first dye capsules, and each of said first conduits projecting through the outer wall.

### Claim 2 (depends on 1)

A protective helmet as set forth in claim 1 including a plurality of second dye capsules directed throughout the second layer, and a plurality of second conduits, with each of said second conduits in communication with an individual one of said second dye capsules, and each of said second conduits extending through the outer wall.
