Abstract
Abstract A protective helmet suitable for safe use by a person having long hair is disclosed. The helmet includes an outer dome-shaped shell of impact-resistant material configured to fit on the head of a wearer. A liner affixed to the inside of the shell snugly positions the helmet on the head and dissipates impact forces received by the outer shell. An aperture formed through the rear portion of the helmet is sized to enable the wearer's hair to be gathered and entrained therethrough, but is sized small enough to prevent harmful impact penetration of an object such as a ball, hockey puck or the like with the wearer's head.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
221 words
A protective helmet of a type suitable for use in a sport that uses a ball having a specified diameter, comprising: a. a generally dome-shaped impact resistant protective skull portion contoured to define an inner surface configured for protectively overlying a human head, having oppositely disposed front and rear surfaces and oppositely disposed sides intermediate said front and rear surfaces, said rear surface defining a lower rear edge; b. a visor portion extending outwardly from said front surface; c. foam padding mounted to the inner surface of said skull portion and selectively positioned for snugly engaging a wearer's head for positioning said skull portion relative to the head and for cushioning the wearer's head from impact forces received by the protective skull portion; and d. said skull portion defining a hair entraining aperture formed through said rear surface thereof, said aperture being sized and configured large enough to allow a gathered length of the wearer's hair to be entrained therethrough but having a maximum width significantly smaller than the specified diameter of the ball for preventing penetrable impact of the ball with the wearer's head through said aperture; and wherein said hair entraining aperture extends continuously upward from and through said lower rear edge such that the wearer's hair can be slid upwardly into said aperture from said lower rear edge.
