Helmet retention system with improved stability
DCFirst Claim
1. A mounting buckle for a safety helmet, the buckle comprising first and second mating members each having an abutment surface, joinder of the first and second mating members bringing the abutment surfaces substantially into contact with each other, each of the mating members being configured for attachment to a respective V-shaped strap having an apex edge, each mating member comprising means for affixing the apex edge of an attached V-shaped strap substantially flush with the abutment surface of the mating member such that joinder of the first and second mating members brings the apices of the V-shaped straps substantially into contact with each other.

Abstract
A mounting buckle for a safety helmet includes at least one mating member configured for attachment to a V-shaped strap having an apex, the apex of the strap being substantially flush with the abutment surface. This configuration channels the tension in the straps along continuous lines, rather than allowing the tension to dissipate in an intervening length of strap.
