1. A webbing adjuster selectively positionable and securable on a bight of webbing, the webbing having a width and a thickness, said adjuster comprising:
- a strap securing component comprising opposed sidewalls with a securing beam extending lengthwise between the sidewalls, the securing beam having a height in a direction perpendicular to the lengthwise direction; and
a strap guiding component movably received between said sidewalls adjacent the securing beam, the strap guiding component defining at least a first opening with a width sufficient to receive a width of webbing and a height sufficient to receive at least two thicknesses of webbing;
wherein said securing beam height is greater than said first opening height and said strap securing and guiding components are configured and dimensioned to slidably receive the bight of webbing around the securing beam and through said at least one opening, and to trap the bight of webbing between the securing beam and strap guiding component in response to a force applied to the strap guiding component when tensioned in a direction opposite the bight of webbing.

9. A helmet strap system, comprising:
-
a first helmet strap adapted to be secured at fore and aft positions on a helmet forming a bight therebetween, the strap having a width and a thickness; a strap securing component comprising opposed sidewalls with a securing beam extending lengthwise between the sidewalls; a strap guiding component movably received between said sidewalls adjacent the securing beam, the strap guiding component defining at least one opening with a height and a width sufficient to receive therethrough the bight of said first helmet strap, said bight passing through said at least one opening and around said securing beam; and a chin strap looped through said at least one opening in the strap guiding component in a direction away from said bight of helmet strap; wherein (i) said securing beam and strap guiding component trap the helmet strap bight therebetween when the chin strap is tensioned away from the helmet strap bight, and (ii) said securing component and said strap guiding component are slideable on the helmet strap bight when untensioned. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method of adjusting a helmet strap system wherein the system includes at least one helmet strap configured to be anchored at fore and aft positions on a helmet, a webbing adjuster slidable on the at least one helmet strap, and a chin strap secured to the webbing adjuster, the method comprising:
-
positioning the webbing adjuster at a desired position on the at least one helmet strap by sliding said adjuster along said helmet strap; and securing the webbing adjuster at the desired position by trapping the helmet strap between cooperating parts of the webbing adjuster in response to tension applied to the chin strap in a direction away from the helmet strap and webbing adjuster.
