摘要： A one-piece adjustable headgear strap is constructed of lightweight material, for example plastic, and therefore is inexpensively manufactured and comfortable to wear. The strap is constructed with an adjustment mechanism that enables it to be easily adjusted around the head of wearer with just one hand. The adjustment mechanism is also integrally formed with the headband of the headgear support and is therefore inexpensive to manufacture due to its one-piece construction.
