Safety helmet lockout system
First Claim
1. An equipment use-prevention lockout system comprising:
- an item of equipment rendered in a non-operational condition until enabled to an operational condition by an enabling means;
a protective apparatus separate from said item of equipment intended to be worn by a user during operation of said item of equipment and having a sensor system for determining that said user has properly secured said protective apparatus to said user; and
said sensor system communicating with said enabling means to permit said enabling means to alter the condition of said equipment from said non-operational condition to said operational condition only when said sensor system has determined that said user has properly secured said protective apparatus to said user, said protective apparatus comprising a protective safety helmet for wearing on a user head and having a chin strap, and a locking buckle lockable and unlockable with an enabling key;
said sensor system comprising a plurality of physio sensors disposed within said chin strap and intended to contact said user during wearing of said helmet when said chin strap is fastened, and a tension sensor for detecting tension within said chin strap;
said sensor system generating a pin or tumbler retracting signal adapted to release said enabling key from said locking buckle only when all of said plurality of physio sensors and said tension sensor indicate that said helmet is properly secured to the head of said user; and
said enabling means of said item of equipment adapted to receive said released enabling key to permit said user to render said item of equipment from said non-operational condition to said operational condition.

Abstract
The Safety Helmet Lockout System comprised of a safety helmet with a uniqely keyed system contained within its cranial webbing and chinstrap that has the ability to sense when said helmet is securely strapped upon the wearers head. The chinstrap contains a locking buckle which releases a uniqely keyed enabling key and/or a signal upon sensing that said safety helmet is securely strapped upon the wearers head. Several means of sensing are possible, but the preferred embodiment employs physio sensors located within the cranial webbing and chinstrap of said safety helmet. The locking buckle which is located on the chinstrap, releases said enabling key or signal after recieving signals from all the physio sensors, and sensing tension in the chinstrap. The released enabling key, or emitted signal, can then be used to access vehicles, sporting goods, industrial equipment, tools, passage locks, and the like. The access locks can range from simple ignition locks and passage locks, to retracting pin or keyed brake systems, keyed clutch systems, and specialty lockout systems for certain applications (such as, but not limited to, skiis, snowboards, and snowmobiles).
