US Patent 10444517 Telescoping strap adjuster

A telescoping strap adjuster is embodied as a gas spring that enables a head strap of a head mounted display system to be worn around an individual's head. The gas spring includes a piston rod that translationally displaces, which adjusts the size of an opening of formed by the head strap. In the default configuration, the piston rod of the telescoping strap adjuster is fully extended, thereby causing the head strap opening to be minimized. A user can provide a force input to enlarge the head strap opening and subsequently don the head mounted display system. Once the force input is ceased, the telescoping strap adjuster reverts towards its default configuration and tightens the head strap such that the opening is tailored for the user's head size.
