Abstract
Abstract In order to permit the quick release of a motorcycle rider's helmet when a bee or wasp is trapped inside the visor, a quick release arrangement for operation with only one hand is provided. The normal strap arrangements for a helmet include a first strap extending from one side of the helmet and carrying two D-Rings secured to the end of this strap. The other strap is threaded through the two D-rings, and then back through the outer one of the two D-rings so that friction between the two portions of the second strap holds the helmet tightly in place. The present disclosure involves the addition of a release member which extends around the second strap between the point where it is threaded through the two D-rings and the point where it extends back through the outer D-ring. By pulling on this release member, the strap assembly may be released with only one hand so that the motorcycle rider can continue guiding the motorcycle with his other hand. An additional stop member such as a ring may be secured to the end of the second strap so that the release member is not lost as a result of full separation of the two straps.
