Abstract
Strap buckles for headgear can be independently adjusted by single-handed operation while the headgear is worn. To tighten the straps, the wearer pulls a strap buckle toward the chin. The adjustment preferably involves a 1:1 length-adjustment ratio, such that the strap is shortened substantially by the amount the wearer pulls on the buckle.
